This paper studies the properties of the solution to the heterogeneous agents model in Den Haan, Judd and Juillard (2008). To solve for the individual policy rules, we use an Euler-equation method iterating on a grid of prespecified points. To compute the aggregate law of motion, we use the...

This paper examines the empirical relevance of an intertemporal model of consumption with dynamically inconsistent decision makers. The model has testable implications concerning the relation between the consumers' degrees of short-run patience (self-control) and their consumption-saving...

We study the determinants of Downward Nominal Wage Rigidity(DNWR) in the context of a new-Keynesian heterogeneous-agent model. Laborproductivity of agents is subject to perfectly insurable idiosyncratic shocks.Wage contracts are signed one period ahead and specify the minimum wagethat the firm...

This paper studies the effect of sovereign risk on capital flows from rich to poor nations in the context of a two-country model where Foreign Direct Investment (FDI) creates positive externalities in domestic production. We show that if externalities are large, a developing country never...

This paper extends the indivisible-labor model by Hansen (1985) and Rogerson (1988) to include multiple consumers who differ in initial wealth and whose labor productivities are subject to idiosyncratic shocks. In the presence of idiosyncratic uncertainty, the optimal allocations for the...

This paper studies the properties of the social utility function defined by the planner's problem of Constantinides (1982). We show one set of restrictions on the optimal planner's policy rule, which is sufficient for constructing the social utility function analytically. For such well-known...

This paper studies the properties of solutions to a log-linearized version of the neoclassical growth model with quasi-geometric discounting. We show that after the log-linearization, the model has indeterminacy and multiplicity of equilibria even though the original non-linear model has a...

This paper presents a computable general equilibrium model of endogenous (stochastic) growth and cycles that can account for two key features of the aggregate data: balanced growth in the long-run and business cycles in the short-run. The model is built on Schumpeter's idea that economic...

This paper studies how the assumption of quasi-geometric (quasi-hyperbolic) discounting affects the individual consumption-savings behavior in the context of the standard one-sector neoclassical growth model with heterogeneous agents. The agents are subject to idiosyncratic shocks and face...

This paper studies the implications of a dynamic general equilibrium model with three production sectors, which are agriculture, industry and services. Due to the assumption of increasing returns in industry and services, our model has multiple equilibria. Two equilibria are stable: one, in...
