This paper explores the implications for less developed countries the hypothesis that workers' productivity depends on the wages they receive. In particular, we show that this hypothesis may explain the high urban wages and unemployment found in many such countries. The market equilibrium is...

We characterize the evolution over time of a network of credit relations among financial agents as a system of coupled stochastic processes. Each process describes the dynamics of individual financial robustness, while the coupling results from a network of liabilities among agents. The average...

There is a widespread belief that when significant market failure occurs, there are strong incentives for non-market institutions to develop which go at least part of the way to remedying the deficiency. We demonstrate that this functionalist position is not in general valid. In particular, we...

While bankers and businessmen have long recognized the importance of finance. financial constraints, and financial institutions, they have played a secondary role in neoclassical economic theory. This paper identifies the economic functions with which financial institutions have been concerned,...

Schumpeter argued that economic downturns had positive effects, in the incentives that it provided for firms to increase their efficiency. Part 1. provides a simple model confirming Schwnpeter's insight At thesame time, the model shows that there are real costs to economic fluctuations which...

This paper presents a simple but quite general framework for analyzing the impact of informational externalities. By identifying the traditional pecuniary effect of these externalities which nets out,the paper greatly simplifies the problem of determining when tax interventions can be Pareto...

This paper focuses on two separate problems. The first is that frequently, the most profitable use of funds involves long-term investments, which militiates for long-term debt contracts. The second problem is to monitor the investor's use of funds, as exemplified by the U.S. S&L saga, and we...

In this paper we investigate the macro-economic equilibria of an economy in which credit contracts have both adverse selection and incentive effects. The terms of credit contracts include both an interest rate and a collateral requirement. We show that in this richer model all types of borrowers...

We analyze consequences of changing the terms of trade between agriculture and industry on capital accumulation and on welfare of workers in different sectors. The issue was central to Soviet industrialization debate and it remains important in today's developing world. Through a simple general...

This paper analyzes equilibrium in labor markets with costly search. Even in steady state equilibrium, identical labor may receive different wages; this may be the case even when the only source of imperfect information is the inequality of wages which the market is perpetuating. When there are...
