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.
