This paper explores optimal fiscal policy in an overlapping-generations general-equilibrium model under uncertainty and the impact on optimal policy of the introduction of a type of policy stickiness intended to account for the stylized fact that major reforms happen infrequently. In general,...

Many recent theoretical papers have come under attack for modeling prices as Geometric Brownian Motion. This process can diverge over time, implying that firms facing this price process can earn infinite profits. We explore the significance of this attack and contrast investment under Geometric...

We investigate the empirical relationship between company investment and measures of uncertainty, controlling for the effect of expected future profitability on current investment decisions. We consider three measures of uncertainty derived from (1) the volatility in the firm's stock returns;...

This paper assesses the economics literature on policy uncertainty, addresses puzzles in that literature, and highlights pertinent empirical regularities. Although much progress has been made in identifying important correlations between uncertainty and economic activity, concerns about causal...
