Distress propagation in complex networks: the case of non-linear DebtRank
pub
- H1
- EIC
public
We consider a dynamical model of distress propagation on complex networks, which we apply to the study of financial contagion in networks of banks connected to each other by direct exposures. The model that we consider is an extension of the DebtRank algorithm, recently introduced in the literature. The mechanics of distress propagation is very simple: When a bank suffers a loss, distress propagates to its creditors, who in turn suffer losses, and so on. The original DebtRank assumes that losses are propagated linearly between connected banks. Here we relax this assumption and introduce a one-parameter family of non-linear propagation functions. As a case study, we apply this algorithm to a data-set of 183 European banks, and we study how the stability of the system depends on the non-linearity parameter under different stress-test scenarios. We find that the system is characterized by a transition between a regime where small shocks can be amplified and a regime where shocks do not propagate, and that the overall the stability of the system increases between 2008 and 2013.

(a cura di) Policies for Happiness
pub
- HB
- HJ
- EIC
none
Curatela
In recent years, debates on the economics of happiness have shown that, over the long-term, well-being is influenced more by social and personal relationships than by income. This evidence challenges the traditional economic policy paradigm that has emphasized income as the primary determinant of well-being. This volume brings together contributions from leading scholars to ask: What should be done to improve the quality of people's lives? Can economic and social changes be made which enhance well-being? What policies are required? How do policies for well-being differ from traditional ones targeted on redistribution, the correction of market inefficiencies, and growth? Are there dimensions of well-being that have been neglected by traditional policies? Is happiness a meaningful policy target? The volume presents reflections and proposals which constitute a first step towards answering these questions.

Social Capital Predicts Happiness Over Time
pub
- HB
- HJ
- EIC
none
The evidence summarized in this chapter documents that GDP is associated with well-being over the business cycle, while this correlation tends to wane over longer periods. Instead, the relationship between social capital and well- being tends to set slowly and to be persistent. This is consistent with both the notion that income is affected by adaptation and social comparisons and, conversely, with the notion that social capital is not affected by these same forces. Moreover, we sum up studies concerning the world-wide most striking cases of the Easterlin paradox, the American, Chinese, and Indian ones. These three countries—amounting to almost half of the world population—exhibit a decline in subjective well-being (SWB), despite a more or less outstanding economic growth in the past few decades. We document that the decline of social capital plays a major role in predicting the decline of happiness in these countries—besides the well-known role of social comparisons. This suggests that the decline of social capital may be a part of the explanation of the Easterlin paradox. Overall, our findings support the view that the basic message of happiness economics should not change, i.e., the centrality of GDP should be reduced. Indeed, social capital—as well as economic growth— can be the target for policies aimed at preserving/fostering it (Helliwell, 2011a; Helliwell, 2011b; Rogers etal., 2011; Bilancini and D’Alessandro, 2012).

JEL Classification: C1, G01.
The two large scale crises that hit the world economy in the last century, i.e. the Great
Depression and the Great Recession, have similar outbreak and recovery patterns with
respect to several macroeconomic variables. In particular, the largest depressions are
likely to be accompanied by stock-market crashes. This study investigates the behavior
of the U.S. stock market before, during and after deep downturns, focusing particularly
on the tails of the return distribution. We develop two automatic procedures to identify
multiple change-points in the tail of financial time series as well as in the co-crash and
co-boom probabilities of different markets. We then apply our methodology to twelve
time series representative of the sectors of the U.S. economy. We find that regime
shifts in the lower tail of the distribution tend to co-occur before deep downturns. Our
results contribute to a better understanding of the origin and systemic nature of large
scale events to make policy interventions more timely and effective.

Keywords: Ethnic diversity, Decentralization, Tax morale, Risk-aversion. JEL Classification: J15, H26, H73
This paper analyzes the relationship between individuals' aversion to ethnic diversity, the degree of fiscal and political decentralization, and tax morale. Our theory is based on the assumption that individuals are risk averse in contributing to the provision of public goods benefiting other ethnic groups, and threfore display a lower tax morale. We find scope for policy intervention-specifically, our model predicts that the effect of individuals' aversion to ethnic diversity on taxmorale is smaller or null in decentralized political and fiscal systems relative to centralized ones. The theory highlights the role of decentralization reforms to cut down inter-ethnic redistribution in con icting environments. We test our results by using individual data from the World Value Survey, and several decentralization measures from Fan et al. (2009). According to our most preferred estimation, a one-scale change in the attitude toward ethnic diversity reduces tax morale of 0.03 in centralized system. We rather find no impact in decentralized states.

La Casa di Giulietta di Antonio Avena. Quando l’architettura diventa coup de théȃtre

Antonio Avena’s House of Juliet. When architecture becomes a coup de théâtre.
This paper will discuss the “restoration” of the so-called House of Juliet in Verona, which was influenced by Antonio Avena and was finally conducted between November 1939 and April 1941. The data from topographical, archaeological and archival sources, together with the historical guide books and postcards, reveal that, up until the 20th century, the location of Juliet’s House was understood to be the casa torre facing via Cappello. After a long series of proposed restoration projects dating back to the early 20th century, the restoration conducted by A. Avena created Juliet’s House as we know it today in the building facing the inner courtyard. Through the study of the archival sources, old photographs and the archaeological analysis of the facies of the building, it is possible to acquire an idea of how the restoration was made and the underlying ideas of the project. The restoration consisted in a combination of recycled fragments, “antiqua spolia”, and architectonical elements emulating ancient ones, in order to create an evocative pastiche. It was meant to recreate a medieval atmosphere and to create a backdrop to the Shakespearian drama.

La gestualità del dolore rituale tra parole e immagini
pub
- N1
- EIC
none
This paper deals with mourning gestures in Roman literary and iconographic productions. Both literature and iconography are thought to be the product of a shared cultural background but, at the same time, they show differences in the way each of them expresses this background: the literary form is dynamic, while the iconographic form seems to be static. Hence, ritual mourning scenes are analyzed either in literature (where some vivid details allow the reader to visualize what is being said through words) or in iconography (where an aoristic image stands for a durative narration). In particular, the analysis focuses on a selection of literary sources that contain vivid descriptions of ritual mourning scenes and date back to a period between the I century BC and the II century AD. They are compared to the conclamatio scenes that are portrayed on some groups of Urban sarcophagi, i.e. children sarcophagi and some mythological ones (depicting the death of Patroclus, Meleager, or Alcestis), all of which date back to the middle Imperial Age. Thus, this paper aims at decoding mourning gestures as well as drawing attention to the similarities and differences that can be detected between the literary horizon and the iconographic one in regard to this particular theme.

Images, Invisibility, and Motion: Brief Essay on Chronophotography, Cinema, and Optical Unconscious
unpub
- BH

paper
This paper is based on an analysis of the notion of “Optical Unconscious” by Walter Benjamin.
It seeks to present an interpretation of this notion in connection with the historical relationship between the birth of cinematic technology on the one hand and, and research conducted during the same period in the field of physiology investigating human and animal movement on the other hand.
To this end I will analyze the following three concepts: (a) alienation, (b) automatism and (c) invisibility.
(a) In Minutiae, Close-up, Microanalysis, Carlo Ginzburg formulates an analogy to describe the “optical unconscious” and juxtaposes it with a page from Marcel Proust in which the alien gaze of the narrator parallels the imperturbable lens of a camera and he experiences the physiognomy of the objects in their anonymous being.
Through reference to this passage, I seek to prove that the meaning of the photographic image does not reside in its ability to reflect its object as something real and familiar, but rather in its ability to alienate this object and make it foreign to the observer.
(b) This paper will link this impersonality of the subject to the concept of automatism and analyze this link through William K.L. Dickson’s Kinetoscopic Record of a Sneeze (1894) as an example of the many images of the time that depicted an involuntary movement on the part of the represented subject, namely an action or series of actions beyond the subject’s control.
I assert that this idea of displaying the ordinariness of an involuntary action constitutes a specificity that both photographic and cinematographic technology are based on.
(c) The comprehensive meaning of the represented subject therefore depends on the device, otherwise it would have been doomed to invisibility. In order to clarify what kind of invisibility is at stake here, my study will take a step back to examine the historical origins of the photo-cinematographic tools used in experimental physiology and the role that representation came to have (the idea of the autonomy of the representation).
Finally, in order to clarify these hypotheses, I shall analyze the case of the French physiologist Étienne-Jules Marey.
By studying physiological theories on motion at the end of XIX Century, this paper will bring the relationship between photography and cinema back to its historical origins and highlight moments of intersection.

Towards an Economy of the Body
unpub

paper
This paper focuses on three main cases: Étienne-Jules Marey (1830-1904), Georges Demeny (1850-1917) and the Gilbreths (Frank B. Gilbreth, 1868-1924 and Lillian M. Gilbreth, 1878-1972), and their respective studies of movement.
More specifically, it investigates Marey’s and Demeny’s experiments with fix plate chronophotography (1883-1886) focused on human locomotion, Demeny’s research with chronophotography on sensitive strip and celluloid film studying gymnastics (1888-1892), and Frank and Lillian Gilbreth’s work on the cyclograph (as expounded in Fatigue Study and Applied Motion Study).
Firstly, the paper analyzes the three different procedural protocols of these experiments in order to identify their similarities and differences and to understand what, if any, experimental model they give rise to. It scrutinizes in particular: a) the position of the scientist’s body in the experimental field and its role in theory (the training of the observer’s/scientist’s body); b) the preparation of the body of the subjects to be analyzed (before the experiments) and the way these bodies were posed in the experimental field (during the experiments); c) the status of the camera’s mechanical body.
Secondly and finally, the paper aims to show how all these regulatory norms serve and enable a certain economy of the body in two interconnected senses: a) economy as a form of reduction. The paper analyzes different ways the body inside the experimental field is isolated/deleted depending on whether it is the scientist’s body, the subject’s body under analysis or the body of the camera; b) economy as a system of efficiency. Beginning from M. Mauss’s notion of “techniques du corps” as a general theoretical framework as well as specific examples of disciplining effects on individuals (See Phéline, Christian. L'image accusatrice. Laplume, France: Association de critique contemporaine en photographie, 1985), this paper seeks to outline the historical role played by the abovementioned studies of the body in developing efficiency (and its relationship with work) as an object of knowledge.

If bn is black and Zn-1<U, then bn is replaced together with a random number Bn of black balls. If bn is red and Zn-1>L, then bn is replaced together with a random number Rn of red balls. Otherwise, no additional balls are added, and bn alone is replaced. In this paper we assume that Rn=Bn.

Dynamic Adverse Selection and the Supply Size

Dynamic adverse selection; Supply size; Frequency of exchanges; Asymmetric information
In this paper we examine the problem of dynamic adverse selection in a stylized market where the quality of goods is a seller's private information while the realized distribution of qualities is public information. We obtain that full trade occurs in every dynamic competitive equilibrium. Moreover, we show that if prices can be conditioned on the supply size then a dynamic competitive equilibrium always exists, while it fails to exist if prices cannot be conditioned on the supply size and the frequency of exchanges is high enough. We conclude that the possibility to condition prices on the supply size allows to reach efficiency in the limit for exchanges becoming more and more frequent, while otherwise the welfare loss due to delays of exchanges remains bounded away from zero.

Under an additional assumption of quasisupermodularity in actions of payoff functions and mild assumptions on the type space - partially ordered and with sets of uncomparable types having negligible size - and on the action space - lattice, second countable and satisfying a separation property with respect to the ordering of actions - we prove that every Nash equilibrium is essentially strict. Further, by building on McAdams (2003, Theorem 1), we prove existence of a strict Nash equilibrium and an evolutionarily stable strategy in a general class of incomplete information games satisfying strict single crossing in types and actions.

Big data, social media, Twitter, hierarchical clustering, unemployment.

The widespread adoption of highly interactive social media like Twitter, Facebook and other platforms allow users to communicate moods and opinions to their social network. Those platforms represent an unprecedented source of information about human habits and socio-economic interactions. Several new studies have started to exploit the potential of these big data as fingerprints of economic and social interactions.
The present analysis aims at exploring the informative power of indicators derived from social media activity, with the aim to trace some preliminary guidelines to investigate the eventual correspondence between social media indices and available labour market indicators at a territorial level. The study is based on a large dataset of about 4 million Italian-language tweets collected from October 2014 to December 2015, filtered by a set of specific keywords related to the labour market. With techniques from machine learning and user’s geolocalization, we were able to subset the tweets on specific topics in all Italian provinces. The corpus of tweets is then analyzed with linguistic tools and hierarchical clustering analysis. A comparison with traditional economic indicators suggests a strong need for further cleaning procedures, which are then developed in detail. As data from social networks are easy to obtain, this represents a very first attempt to evaluate their informative power in the Italian context, which is of potentially high importance in economic and social research.

A Network Model characterized by a Latent Attribute Structure with Competition

technical_report
Complex systems, social networks, Indian Buffet process
The quest for a model that is able to explain, describe, analyze and simulate real-world complex networks is of uttermost practical, as well as theoretical, interest. In fact, networks can be a natural way to represent many phenomena; often, they arise from a complex interweaving of some features of the nodes. For example, in a co-authorship network, a link stems more easily between authors with similar interests; similarly, in a genetic regulatory network, links are affected by the different biological functions of the regulators.
In this paper we introduce and study a novel network model that is based on a latent attribute structure: this model, inspired by a generalization of the Indian Buffet process, is simple and contains a small number of parameters, with a clear and intuitive role. Each node is characterized by a number of features and the probability of the existence of an edge between two nodes depends on the features they share; the number of possible features is not fixed a priori and can grow indefinitely. Moreover, a random fitness parameter is introduced for each node in order to determine its ability to transmit its own features to other nodes; this behavior is added on top of a process of Indian-Buffet type. Because of the fitness property, a node’s connectivity does not depend on its age alone, so that also
“young but fit” nodes are able to compete and succeed in propagating their features and acquiring links. We also show how, considering the resulting bipartite node-attribute network, it is possible to gain some insight about which nodes were originally the most “fit”.
Our model for this bipartite network depends on few parameters, that are characterized by their straightforward interpretation and by the availability of proper estimators. Even if the parameters are easy to interpret and tune, the model is general enough to represent
complex phenomena—e.g., homophily, heterophily, or any interplay between features. We provide some theoretical as well as experimental results regarding the power-law behavior of the model and the proposed tools for the estimation of the parameters. We also show, through a number of experiments, how the proposed model naturally captures most local and global properties (e.g., degree distributions, connectivity and distance distributions)
real networks exhibit.

Assessing financial distress dependencies in OTC markets: a new approach using trade repositories data

Financial distress interdependence, Joint probability of distress, Interest rate swaps, Systemic risk, Micro-founded trade repositories’ data
In this paper, we study the relationships among financial market sub-segments as a way to identify potential financial distress through increased co-movements among them. To study how sub-markets are mutually co-dependent, we combine granular data on over-the-counter derivatives by trade repositories and the joint probability of distress (JPoD) approach introduced by the International Monetary Fund. We define an indicator that combines several distress drivers and observe that results on co-dependencies are similar to those that would be expected: similarities between financial and contractual terms seem to be responsible for stronger co-movements among sub-markets. However, high values for JPoD even in correspondence of quite dissimilar sub-markets suggest the presence of other drivers that should be investigated in future research. To the best of our knowledge, this is the first empirical study on systemic risk assessment based on micro-founded trade repositories’ data on interest rate swaps.

Bridging or bonding? Preferences for redistribution and social capital in Russia

Keywords: preferences for redistribution; inequality; social capital; trust; corruption; Russia
JEL-codes: Z13, H10
Does bridging or bonding social capital matter for redistribution preferences? Existing literature demonstrates causal link between measures of social capital and such preferences but does it mostly for developed countries with good enforcement of formal rules and without a distinction between two completely different types of social capital. We argue that welfare state relies on contributions from an immense number of anonymous citizens, thus attitudes towards strangers, i.e. generalized trust and solidarity should be salient. Using two surveys of about 34,000 and 37,000 Russians we prove this proposition showing the importance of the bridging type but not the bonding one. Instrumenting social capital with education, climate and distance from Moscow we deal with endogeneity concerns. Additionally we claim that connection between social capital and redistribution preferences for less developed countries such as Russia could be similar to developed countries.

Ereditare il futuro: dilemmi sul patrimonio culturale
pub
- K1
- EIC
none
Il libro ricostruisce le regole, le prassi e i problemi della gestione del patrimonio culturale, soffermandosi su quattro dilemmi che segnano le politiche di questo settore: pubblico vs privato (cosa è davvero la valorizzazione?); «retenzione» vs esportazione (come circolano le opere d’arte?); in-house vs outsourcing (chi progetta le mostre?); natura vs cultura (qual è il rapporto tra ambiente, paesaggio e cultura?). I dilemmi si intrecciano con l’assetto delle istituzioni chiamate a risolverli, con l’emergere di interessi globali e con la necessità di adottare misure oltre il presente: il patrimonio culturale non è solo memoria del passato, ma anche eredità del futuro.

The article deals with the 2014 Reform of the Italian Ministry for Culture and Tourism, which has triggered controversial responses from scholars, media and public opinion. Moving from the actual legal and institutional context, the author aims at demonstrating the weaknesses of the main critiques formulated against the reform. This will allow him to address the main problems that still affect the Ministry and to illustrate the next steps that must be taken in order to help and improve the reformation process.

SCOPUS ID: 2-s2.0-84953209929; WOS Accession Number: WOS:000374576900002
In this paper, we build a cumulative innovation model to understand the role of both success and failure in the learning dynamics that characterize pharmaceutical R&D. We test the prediction of our model by means of a unique dataset that combines patent information with R&D projects, thus distinguishing patents related to successfully marketed products from those covering candidate drugs that failed in clinical trials. Results confirm model predictions showing that patents associated with successfully completed projects receive more citations than those associated with failed projects. However, we also show that failed projects can be in turn cited more often than patents lacking clinical or preclinical information. We further explore the `black box' of innovation, providing evidence that both successes and failures contribute to R&D investment decisions and knowledge dynamics in science-driven sectors.

Entangling Credit and Funding Shocks in Interbank Markets
pub
- HA
- HB
- HG
- EIC
public
Credit and liquidity shocks represent main channels of financial contagion for interbank lending markets. On one hand, banks face potential losses whenever their counterparties are under distress and thus unable to fulfill their obligations. On the other hand, solvency constraints may force banks to recover lost fundings by selling their illiquid assets, resulting in effective losses in the presence of fire sales—that is, when funding shortcomings are widespread over the market. Because of the complex structure of the network of interbank exposures, these losses reverberate among banks and eventually get amplified, with potentially catastrophic consequences for the whole financial system. Inspired by the recently proposed Debt Rank, in this work we define a systemic risk metric that estimates the potential amplification of losses in interbank markets accounting for both credit and liquidity contagion channels: the Debt-Solvency Rank. We implement this framework on a dataset of 183 European banks that were publicly traded between 2004 and 2013, showing indeed that liquidity spillovers substantially increase systemic risk, and thus cannot be neglected in stress-test scenarios. We also provide additional evidence that the interbank market was extremely fragile up to the global financial crisis, becoming slightly more robust only afterwards.

Science of science policy; Scientific impact; R&D funding; International collaborations
Abstract We discuss, at the macro-level of nations, the contribution of research funding and rate of international collaboration to research performance, with important implications for the “science of science policy”. In particular, we cross-correlate suitable measures of these quantities with a scientometric-based assessment of scientific success, studying both the average performance of nations and their temporal dynamics in the space defined by these variables during the last decade. We find significant differences among nations in terms of efficiency in turning (financial) input into bibliometrically measurable output, and we confirm that growth of international collaboration positively correlate with scientific success—with significant benefits brought by {EU} integration policies. Various geo-cultural clusters of nations naturally emerge from our analysis. We critically discuss the factors that potentially determine the observed patterns.

Comparative Regional Integration: Governance and Legal Models
pub
- K1
- EIC
none
Comparative Regional Integration: Governance and Legal Models is a groundbreaking comparative study on regional or supranational integration through international and regional organizations. It provides the first comprehensive and empirically based analysis of governance systems by drawing on an original sample of 87 regional and international organizations. The authors explain how and why different organizations select specific governance processes and institutional choices, and outline which legal instruments – regulatory, organizational or procedural – are adopted to achieve integration. They reveal how different objectives influence institutional design and the integration model, for example a free trade area could insist on supremacy and refrain from adopting instruments for indirect rule, while a political union would rather engage with all available techniques. This ambitious work merges different backgrounds and disciplines to provide researchers and practitioners with a unique toolbox of institutional processes and legal mechanisms, and a classification of different models of regional and international integration.

Central limits; Polya urn; Randomly reinforced urn; stable convergence
We consider a variant of the randomly reinforced urn where more balls can be simultaneously drawn out and balls of different colors can be simultaneously added. More precisely, at each time-step, the conditional distribution of the number of extracted balls of a certain color given the past is assumed to be hypergeometric. We prove some central limit theorems in the sense of stable convergence and of almost sure conditional convergence, which are stronger than convergence in distribution. The proven results provide asymptotic confidence intervals for the limit proportion, whose distribution is generally unknown. Moreover, we also consider the case of more urns subjected to some random common factors.

Fluctuation Theorems for Synchronization of Interacting Polya's urns

technical_report
Fluctuation theorem, Interacting system, Stable convergence, Synchronization, Urn model
Available online 23 October 2015
We consider a model of N two-colors urns in which the reinforcement of each urn depends also on the content of all the other urns. This interaction is of mean-field type and it is tuned by a parameter \alpha in [0,1]; in particular, for \alpha=0 the N urns behave as N independent Polya's urns. For \alpha>0 urns synchronize, in the sense that the fraction of balls of a given color converges a.s. to the same (random) limit in all urns. In this paper we study fluctuations around this synchronized regime. The scaling of these fluctuations depends on the parameter \alpha. In particular, the standard scaling t^{-1/2} appears only for \alpha>1/2. For \alpha\geq 1/2 we also determine the limit distribution of the rescaled fluctuations. We use the notion of stable convergence, which is stronger than convergence in distribution.

Basis Risk in Static versus Dynamic Longevity Risk Hedging

Keywords: longevity risk, basis risk, static vs. dynamic hedging, longevity swaps, longevity bonds
JEL Classification: G22, G32
This paper provides a simple model for basis risk in a longevity framework, by separating common and idiosyncratic risk factors. Basis risk is captured by a single parameter, that measures the co-movement between the portfolio and the reference population. In this framework, the paper sets out the static, swap-based hedge for an annuity, and compares it with the dynamic, delta-based hedge, achieved using longevity bonds. We assume that the longevity intensity is distributed according to a CIR-type process and provide closed-form derivatives prices and hedges, also in the presence of an analogous CIR process for interest rate risk.

We present new evidence about the relationship between military conflict and city
population growth in Europe from the fall of Charlemagne’s empire to the start of
the Industrial Revolution. Military conflict was a main feature of European history.
We argue that cities were safe harbors from conflict threats. To test this argument,
we construct a novel database that geocodes the locations of more than 800 conflicts
between 800 and 1799. We find a significant, positive, and robust relationship that
runs from conflict exposure to city population growth. Our analysis suggests that
military conflict played a key role in the rise of urban Europe.

Technology Diffusion on the International Trade Network
pub

- EIC
public
Keywords: Technology diffusion, Trade network, Average geodesic distance - JEL Codes: F10, O33
Technological innovations generate knowledge spillovers—non-innovators benefit through the adoption, imitation, and extension of new technologies. International trade facilitates technology diffusion by providing importing countries access to technical knowledge that they can potentially internalize. Previous studies of the effect of trade on technology diffusion typically only consider the impact of direct (bilateral) trade on indirect measures of technology (e.g., total factor productivity). We contend that the analysis of trade's impact on technology diffusion would be more accurately assessed by using direct measures of specific technologies (e.g., intensity levels) and by allowing for the influence of both the direct and indirect effects of trade in the analysis. The latter is accomplished by modeling the international trade system as a weighted network, which quantifies both direct and indirect trade linkages. Combining trade data with data on the adoption of specific technologies, we find that the network effects of trade play a significant role in technology diffusion. In most cases, countries that are better-connected on the trade network have higher technology intensities. Further support for the importance of trade is provided by the finding that for “outdated” technologies, better-connected countries have lower technology intensities because of their adoption of newer, substitute technologies.

The paper looks at the importance of the true business model in shaping the risk profile of
financial institutions. We adopt a novel indirect clustering approach to enrich the classic bank
business model classification on a global data set including about 11,000 banks, both listed and
non-listed representing more than 180 countries over the period 2005-2014. A comprehensive
list of global distress events, which combines bankruptcies, liquidations, defaults, distressed
mergers, and public bailouts, is regressed against financial statement ratios (i.e. proxies for
CAMELS) and controlling for macro and sectoral effects using a rare-event logit model. Our
findings suggest that individual characteristics along with macro and sectoral factors contribute
differently, sometimes with opposite sign, to the likelihood of distress and to the volatility
of business models with the exception of liquidity whose contribution appears exogenous to
business model choice. By capturing the switching behaviour across groups, we find that
business model volatility exacerbates vulnerability and distress, especially if moving from
wholesale-oriented to deposit oriented groups.

Statistically validated network of portfolio overlaps and systemic risk
pub
- HA
- EIC
public
Common asset holding by financial institutions (portfolio overlap) is nowadays regarded as an important channel for financial contagion with the potential to trigger fire sales and severe losses at the systemic level. We propose a method to assess the statistical significance of the overlap between heterogeneously diversified portfolios, which we use to build a validated network of financial institutions where links indicate potential contagion channels. The method is implemented on a historical database of institutional holdings ranging from 1999 to the end of 2013, but can be applied to any bipartite network. We find that the proportion of validated links (i.e. of significant overlaps) increased steadily before the 2007–2008 financial crisis and reached a maximum when the crisis occurred. We argue that the nature of this measure implies that systemic risk from fire sales liquidation was maximal at that time. After a sharp drop in 2008, systemic risk resumed its growth in 2009, with a notable acceleration in 2013. We finally show that market trends tend to be amplified in the portfolios identified by the algorithm, such that it is possible to have an informative signal about institutions that are about to suffer (enjoy) the most significant losses (gains).

A continuous-time stochastic model for the mortality surface of multiple populations
pub
- HB
- EIC
public
imt_eic_working_paper
Keywords: multi-population mortality, mortality surface, continuous-time
stochastic mortality, Kalman filter estimation, centralized data fusion.
JEL classification: C13, C38, G22, J11.
We formulate, study and calibrate a continuous-time model for
the joint evolution of the mortality surface of multiple populations. We model
the mortality intensity by age and population as a mixture of stochastic latent
factors, that can be either population-specific or common to all populations.
These factors are described by affine time-(in)homogenous stochastic processes.
Traditional, deterministic mortality laws can be extended to multi-population
stochastic counterparts within our framework. We detail the calibration pro-
cedure when factors are Gaussian, using centralized data-fusion Kalman filter.
We provide an application based on the mortality of UK males and females.
Although parsimonious, the specification we calibrate provides a good fit of
the observed mortality surface (ages 0-99) of both sexes between 1960 and
2013.

Neuroscience Evidence for Economic Humanism in Management Science: Organizational Implications and Strategy
pub
- HD28

Neuroeconomics; fMRI, Organizational Neuroscience; Social Neuroscience
Globalization phenomena and Information & Communication Technology (ICT) are producing deep changes worldwide. The economic environment and society where firms both cooperate and compete with each other are rapidly changing leading firms towards recognizing the role of intangible resources as a source of fresh competitive advantage. Experience, innovation and the ability to create new knowledge completely arise from the act of human resources inviting firms to focus on how to generate and shape knowledge. Therefore, the future of firms depends greatly on how managers are able to explore and exploit human resources. However, without a clear understanding of the nature of human beings and the complexity behind human interactions, we cannot understand the theory of organizational knowledge creation. Thus, how can firms discover, man- age and valorize this “human advantage”? Neuroscience can increase the understanding of how cognitive and emotional processes work; in doing so, we may be able to better understand how individuals involved in a business organization make decisions and how external factors influence their behavior, especially in terms of commitment activation and engagement level. In this respect, a neuroscientific approach to business can support managers in decision-making processes. In a scenario where economic humanism plays a central role in the process of fostering firms’ competitiveness and emerging strategies, we believe that a neuroscience approach in a business organization could be a valid source of value and inspiration for manager decision-making processes.

Abstract in Atti di convegno
As the effects of climate change unfold and become more visible, infrastruc- tures, especially those related to the distribution of water are the most exposed to the deep changes expected in the next years. Water is fundamental for peo- ple, and for infrastructures like energy, waste, and food production. Water sus- tainability is then a fundamental aspect to address by an efficient use of the resources and the maintenance of quality standards adopting a management science perspective. Therefore, water industry and infrastructure need a deep transformation, and we claim that this transformation is the result of a synergy between different fields or research. Our paper presents a managerial framework based on a complex systems used to reshape and optimize in different meanings the performance of the water infrastructure through the development of a case study in Italy. Our framework, called Acque 2.0 (Water 2.0) is based on these pillars: 1. The current and future scenarios for water management 2. Management science and water 3. Digitalization of water infrastructure 4. Increase the network resiliency and quality of service using complex networks 5. Use of predic- tive maintenance methods based on network simulations and big data 6. Involve utilities, regulators, policy makers, and citizens 7. Remarks and conclusion. The case study will be developed in the municipality of Viareggio, characterized by old infrastructures, seasonal variation of population, and water scarcity.

Oskar Kokoschka (1886-1980) engraved the two drypoints Das Streitgespräch and Das Tribunal between 1967 and 1968, within a series of 12, to illustrate Aristophanes’ The Frogs (Βάτραχοι, 405 BC). These two artworks comment on the concept of justice, stress the artist’s political engagement and directly refer to the political turmoil which struck Greece in the second half of 1960s.

Modularities maximization in multiplex network analysis using Many-Objective Optimization
pub
- QA75
- QC
- EIC

paper
Nowadays, social network analysis receives big attention from academia, industries and governments. Some practical applications such as community detection and centrality in economic networks have become main issues in this research area. Community detection algorithm for complex network analysis is mainly accomplished by the Louvain Method that seeks to find communities by heuristically finding a partitioning with maximal modularity. Traditionally, community detection applied for a network that has homogeneous semantics, for instance indicating friend relationship between people or import-export relationships between countries etc. However we increasingly deal with more complex network and also with so-called multiplex networks. In a multiplex network the set of nodes stays the same, while there are multiple sets of edges. In the analysis we would like to identify communities, but different edge sets give rise to different modularity optimizing partitions into communities. We propose to view community detection of such multilayer networks as a many-objective optimization problem. For this apply Evolutionary Many Objective Optimization and compute the Pareto fronts between different modularity layers. Then we group the objective functions into community in order to better understand the relationship and dependence between different layers (conflict, indifference, complementarily). As a case study, we compute the Pareto fronts for model problems and for economic data sets in order to show how to find the network modularity tradeoffs between different layers.

Model-based evaluation of scientific impact indicators
pub
- QC
- EIC
public
Using bibliometric data artificially generated through a model of citation dynamics calibrated on empirical data, we compare several indicators for the scientific impact of individual researchers. The use of such a controlled setup has the advantage of avoiding the biases present in real databases, and it allows us to assess which aspects of the model dynamics and which traits of individual researchers a particular indicator actually reflects. We find that the simple average citation count of the authored papers performs well in capturing the intrinsic scientific ability of researchers, regardless of the length of their career. On the other hand, when productivity complements ability in the evaluation process, the notorious h and g indices reveal their potential, yet their normalized variants do not always yield a fair comparison between researchers at different career stages. Notably, the use of logarithmic units for citation counts allows us to build simple indicators with performance equal to that of h and g. Our analysis may provide useful hints for a proper use of bibliometric indicators. Additionally, our framework can be extended by including other aspects of the scientific production process and citation dynamics, with the potential to become a standard tool for the assessment of impact metrics.

The Water Suitcase of Migrants: Assessing Virtual Water Fluxes Associated to Human Migration
pub
- HA
- HC
- EIC
public
Economics of migration; Water resources; Economic geography; China; National security; International trade
Disentangling the relations between human migrations and water resources is relevant for food security and trade policy in water-scarce countries. It is commonly believed that human migrations are beneficial to the water endowments of origin countries for reducing the pressure on local resources. We show here that such belief is over-simplistic. We reframe the problem by considering the international food trade and the corresponding virtual water fluxes, which quantify the water used for the production of traded agricultural commodities. By means of robust analytical tools, we show that migrants strengthen the commercial links between countries, triggering trade fluxes caused by food consumption habits persisting after migration. Thus migrants significantly increase the virtual water fluxes and the use of water in the countries of origin. The flux ascribable to each migrant, i.e. the "water suitcase", is found to have increased from 321 m3/y in 1990 to 1367 m3/y in 2010. A comparison with the water footprint of individuals shows that where the water suitcase exceeds the water footprint of inhabitants, migrations turn out to be detrimental to the water endowments of origin countries, challenging the common perception that migrations tend to relieve the pressure on the local (water) resources of origin countries.

Keywords: Economic integration, Price convergence, Product launches, European Single Market, Healthcare, Pharmaceutical industry, Pricing.
JEL codes: F15; I11; L65; L11; L51
In this paper we document a process of price convergence in the European market for pharmaceuticals and relate it to access to innovative medicines in individual countries. The EU is a peculiar case study, where free circulation of goods exists, but pricing policies are designed and implemented by Member States. Thanks to a unique census database on product sales and launches
for fifteen EU countries, we detect a process of price convergence, both in nominal and in real
terms. Therefore, we find that a faster rate of price convergence and a lower income per capita are
associated with stronger delays in launches of new medicines. Moreover, country delays tend to
be higher for innovative and first in class chemical compounds. Our results suggest that inefficiencies arise from drugs regulation, when countries widely differ in income per capita, public finance
sustainability conditions, and regulatory frameworks. Policies of external reference pricing tend to
exacerbate welfare losses. A policy of differential pricing is suggested, in order to take into account
both therapeutic value and willingness to pay.

The Accounting Network: How Financial Institutions React to Systemic Crisis
pub
- HB
- HG
- EIC
public
The role of Network Theory in the study of the financial crisis has been widely spotted in the latest years. It has been shown how the network topology and the dynamics running on top of it can trigger the outbreak of large systemic crisis. Following this methodological perspective we introduce here the Accounting Network, i.e. the network we can extract through vector similarities techniques from companies’ financial statements. We build the Accounting Network on a large database of worldwide banks in the period 2001–2013, covering the onset of the global financial crisis of mid-2007. After a careful data cleaning, we apply a quality check in the construction of the network, introducing a parameter (the Quality Ratio) capable of trading off the size of the sample (coverage) and the representativeness of the financial statements (accuracy). We compute several basic network statistics and check, with the Louvain community detection algorithm, for emerging communities of banks. Remarkably enough sensible regional aggregations show up with the Japanese and the US clusters dominating the community structure, although the presence of a geographically mixed community points to a gradual convergence of banks into similar supranational practices. Finally, a Principal Component Analysis procedure reveals the main economic components that influence communities’ heterogeneity. Even using the most basic vector similarity hypotheses on the composition of the financial statements, the signature of the financial crisis clearly arises across the years around 2008. We finally discuss how the Accounting Networks can be improved to reflect the best practices in the financial statement analysis.

Detecting early signs of the 2007–2008 crisis in the world trade
pub

- EIC
public
Since 2007, several contributions have tried to identify early-warning signals of the financial crisis. However, the vast majority of analyses has focused on financial systems and little theoretical work has been done on the economic counterpart. In the present paper we fill this gap and employ the theoretical tools of network theory to shed light on the response of world trade to the financial crisis of 2007 and the economic recession of 2008–2009. We have explored the evolution of the bipartite World Trade Web (WTW) across the years 1995–2010, monitoring the behavior of the system both before and after 2007. Our analysis shows early structural changes in the WTW topology: since 2003, the WTW becomes increasingly compatible with the picture of a network where correlations between countries and products are progressively lost. Moreover, the WTW structural modification can be considered as concluded in 2010, after a seemingly stationary phase of three years. We have also refined our analysis by considering specific subsets of countries and products: the most statistically significant early-warning signals are provided by the most volatile macrosectors, especially when measured on developing countries, suggesting the emerging economies as being the most sensitive ones to the global economic cycles.

Economic cycles and their synchronization: a
comparison of cyclic modes in three European countries
pub
- HB

none
Advanced spectral methods; Business cycles;European Union; Frequency domain; Time domain
The present work applies singular spectrum analysis (SSA) to the study of
macroeconomic
uctuations in three European countries: Italy, The Netherlands,
and the United Kingdom. This advanced spectral method provides valuable
spatial and frequency information for multivariate data sets and goes far
beyond the classical forms of time domain analysis. In particular, SSA enables
us to identify dominant cycles that characterize the deterministic behavior of
each time series separately, as well as their shared behavior. We demonstrate its
usefulness by analyzing several fundamental indicators of the three countries'
real aggregate economy in a univariate, as well as a multivariate setting. Since
business cycles are international phenomena, which show common characteristics
across countries, our aim is to uncover supranational behavior within the
set of representative European economies selected herein. Finally, the analysis
is extended to include several indicators from the U.S. economy, in order to
examine its in
uence on the European economies under study and their interrelationships.

Developing sustainable cultural policies in Turkey: an investigation of public opinion on the theatre scene

Published online 27 Jan 2015
The arts scene in Turkey has been witnessing many discussions with the revealing of the governmental reform agenda on the state support model for the arts that includes establishment of an arts council type institution, the closure of the State Theatres and, the State Opera and Ballet. Nevertheless, despite strong public criticism on this reform agenda, there has never been any comprehensive research to reflect the public opinion. Therefore, this study aims to contribute to recent discussions by providing data on public opinion regarding such a fundamental change, with a particular focus on theatre. Towards this end, a survey was conducted in Istanbul. The findings demonstrate that the majority, including both users and non-users of theatre, value the State Theatres and are in favour of sustaining it. There is also a common belief that in case of the State Theatres’ closure, the private theatres cannot undertake its public mission.

A generation-attraction model for renewable energy flows in Italy: A complex network approach

network filterin
In recent years, in Italy, the trend of the electricity demand and the need to connect a large number of renewable energy power generators to the power-grid, developed a novel type of energy transmission/distribution infrastructure. The Italian Transmission System Operator (TSO) and the Distribution System Operator (DSO), worked on a new infrastructural model, based on electronic meters and information technology. In pursuing this objective it is crucial importance to understand how even more larger shares of renewable energy can be fully integrated, providing a constant and reliable energy background over space and time. This is particularly true for intermittent sources as photovoltaic installations due to the fine-grained distribution of them across the Country. In this work we use an over-simplified model to characterize the Italian power grid as a graph whose nodes are Italian municipalities and the edges cross the administrative boundaries between a selected municipality and its first neighbours, following a Delaunay triangulation. Our aim is to describe the power flow as a diffusion process over a network, and using open data on the solar irradiation at the ground level, we estimate the production of photovoltaic energy in each node. An attraction index was also defined using demographic data, in accordance with average per capita energy consumption data. The available energy on each node was calculated by finding the stationary state of a generation-attraction model.

The new digital revolution of big data is deeply changing our capability of understanding society and forecasting the outcome of many social and economic systems. Unfortunately, information can be very heterogeneous in the importance, relevance, and surprise it conveys, affecting severely the predictive power of semantic and statistical methods. Here we show that the aggregation of web users’ behavior can be elicited to overcome this problem in a hard to predict complex system, namely the financial market. Specifically, our in-sample analysis shows that the combined use of sentiment analysis of news and browsing activity of users of Yahoo! Finance greatly helps forecasting intra-day and daily price changes of a set of 100 highly capitalized US stocks traded in the period 2012–2013. Sentiment analysis or browsing activity when taken alone have very small or no predictive power. Conversely, when considering a news signal where in a given time interval we compute the average sentiment of the clicked news, weighted by the number of clicks, we show that for nearly 50% of the companies such signal Granger-causes hourly price returns. Our result indicates a “wisdom-of-the-crowd” effect that allows to exploit users’ activity to identify and weigh properly the relevant and surprising news, enhancing considerably the forecasting power of the news sentiment.
