This paper deals with credit market imperfections and idiosyncratic risks in a two–sector heterogeneous agent dynamic general equilibrium model of occupational choice. We focus especially on the effects of tightening financial constraints on macroeconomic performance, entrepreneurial...

This paper examines the effects of credit market imperfections and idiosyncratic risks on occupational choice, capital accumulation, as well as on the income and wealth distribution in a two sectore heterogeneous agent general equilibrium model. Workers and firm owners are subject to...

This paper studies optimal dynamic tax policy under the threat of political reform. A policy will be reformed ex post if a large enough political coalition supports reform; thus, sustainable policies are those that will continue to attract enough political support in the future. We find that...

This paper examines the pattern of international capital flows in a two–sector dynamic general equilibrium heterogeneous agent model with financial frictions and idiosyncratic entrepreneurial risk. Countries differ only with respect to the tightness of constraints on the domestic credit...

The wealthy hand-to-mouth are households who hold little or no liquid wealth (cash, checking, and savings accounts), despite owning sizable amounts of illiquid assets (assets that carry a transaction cost, such as housing or retirement accounts). We use survey data on household portfolios for...

We develop a simple dynamic model of decision making in the presence of moral constraints. Norm violations induce a temporal feeling of guilt that depreciates with time. Due to endogenous fluctuations of guilt, people exhibit a dynamic inconsistency in social preferences—a behavior we term...

Do asset prices affect real activity? This question has taken on a new importance in recent years, as asset values first surged at the end of 1990s and, thereafter, dramatically retreated. This report reviews the available theoretical and empirical evidence regarding asset price and wealth...

The OLG model of Allais and Samuelson retains the methodological assumptions of agent optimization and market clearing from the Arrow-Debreu model, yet its equilibrium set has different properties: Pareto inefficiency, indeterminacy, positive valuation of money, and a golden rule equilibrium in...
