This paper quantifies the effect of time-varying employment risks on the fluctuations of aggregate consumption in a dynamic general equilibrium with incomplete markets. A government's redistribution policy through provision of unemployment insurance can cause a positive correlation between...

This paper demonstrates endogenous fluctuations of aggregate investments when firm-level investments follow an (S,s) policy and exhibit strategic complementarity. We present a method to characterize the aggregate fluctuations that arise from the interaction of the (S,s) policies. A closed-form...

This paper investigates the aggregate fluctuations in production and demand components when a firm's investment decision takes the form of (S,s) policies. In the field of large-dimensional non-linear dynamical systems, it is a commonly accepted view that a system of coupled non-linear...

This paper proposes a model of endogenous fluctuations in investment. A monopolistic producer has an incentive to invest when the aggregate demand is high. This causes a propagation of investment across sectors. When the investment follows an (S,s) policy, the propagation size can exhibit a...

This paper analytically demonstrates that the tails of income and wealth distributions converge to a Pareto distribution in a variation of the Solow or Ramsey growth model where households bear idiosyncratic investment shocks. The Pareto exponent is shown to be decreasing in the shock variance,...

This paper studies the effect of strategic complementarity among firms' lumpy investments on the fluctuations of aggregate investments. We investigate an extensive panel data set on Italian manufacturing firms. We first show that the fluctuations of fraction of firms that experience large...

This paper presents a model of endogenous fluctuations of investment and output at the business cycles frequencies. Aggregate investments fluctuate endogenously due to the strategic complementarity of micro-level lumpy investments. The investment fluctuations are transmitted to the output via...
