This article presents a model of the emergent class structure, in which a society inhabited by inherently identical households may be endogenously split into the rich bourgeoisie and the poor proletariat. For some parameter values, the model has no steady state where all households remain...

The welfare analysis of P. A. Diamond's overlapping generations model is often restricted to a steady-state comparison. This paper demonstrates that a simple diagrammatic technique is useful for a Pareto welfare analysis. In particular, it shows that capital saving technological progress could...

We propose a new approach to model costly international trade, which includes the standard approach, the "iceberg" transport cost, as a special case. The key idea is to make the technologies of supplying the good depend on the destination of the good. To demonstrate our approach, we extend the...

This paper extends Diamond's OG model by allowing the agents to make the retirement decision. Earning a higher wage income when young not only enables the agents to save more. It also induces more agents to retire early and gives an additional incentive to save more for retirement. This leads to...

This paper investigates the effects of financial market globalization on the inequality of nations. The world economy consists of inherently identical countries, which could differ only in their levels of capital stock. Each country is represented by the standard overlapping generations model,...

In a world where credit relationships are subject to a variety of agency problems, corporate governance, contractual enforcement, and the balance sheet condition of the business sector are among many factors that can play an important role in the allocation of resources. This paper offers two...

This paper develops a theoretical framework to understand mechanisms behind the rise and fall of class societies. The dynamics is described by the joint evolution of the wage rate, the vertical division of labor between employers and workers, and the distribution of household wealth. The model...

This paper builds models of nonlinear dynamics in the aggregate investment and borrower net worth and uses them to study the causes and nature of endogenous credit cycles. The basic model has two types of projects: the Good and the Bad. The Bad is highly productive, but, unlike the Good, it...

This paper develops models of endogenous credit cycles. The basic model has two types of profitable investment projects: the Good and the Bad. Unlike the Good, the Bad contributes little to improve the net worth of other borrowers. Furthermore, it is relatively difficult to finance externally...
