This paper develops a simple model of macroeconomic behavior which incorporates the impact of financial market "imperfections," such as those generated by asymmetric information in financial markets. These information asymmetries may lead to breakdowns in markets, like that for equity, in which...

In this paper, we investigate the descriptive and normative properties of competitive equilibrium with moral hazard when firms offer "price contracts" which allow clients to purchase as much insurance as they wish at the quoted prices. We show that a price equilibrium always exists and is one of...

When Russia launched mass privatization, it was widely believed that it would create a powerful constituency for the rule of law. That didn't happen. We present a dynamic equilibrium model of the political demand for the rule of law and show that beneficiaries of mass privatization may fail to...

This paper reviews and puts into perspective recent work reassessing the first and second Fundamental Theorems of Welfare Economics. It assesses the implications of the Greenwald-Stiglitz theorem establishing the (constrained) Pareto inefficiency of market economies with imperfect information...

In this paper we propose an Open Economy Financial Accelerator model along the lines of Greenwald-Stiglitz (1993) close in spirit but different in many respects from the one proposed by Greenwald (1998.) The first goal of the paper is to provide a taxonomy of the effects of a devaluation in this...

This paper formulates a simple model of "perfect community competition." It is shown that (1) the equilibrium is Pareto optimal; (2) communities will, in general, be heterogeneous; not all individuals will have the same tastes; but (3) all individuals of a given skill within the community will...

This paper considers two sets of theories attempting to explain wage rigidities and unemployment: implicit contract theory and the efficiency wage theory. The basic thesis of the paper is that the former set of theories do not provide a convincing explanation of the kind of wage rigidity which...

In the last few years, there has developed a large literature, sometimes referred to as the new "public finance," providing a quantitative analysis of a number of traditional problems within the field. This paper is concerned with surveying, or interpreting, what can be learned from this...
