The paper proposes a dynamic partial equilibrium model where competitive firms with constant return to scale technology are risk averse. Firms are subject to output price uncertainty. We show that it is possible that the investment-uncertainty relationship is positive even when firms have a high degree of risk aversion. Indeed, the paper shows that risk aversion can explain the negative relationship between investment and uncertainty only in a static context. In a dynamic framework, the linkage between periods can lead risk aversion to have a positive effect on investment when uncertainty increases. Moreover, the paper shows that investment should be positively correlated with uncertainty for reasonable values of the preference and technological parameters.
