We present a model of the labor market with asymmetric information in which the equilibrium of the' market generates unemployment and job queues so that wages may serve as an effective screening device. This happens because more productive workers -- within any group of individuals with a given...

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...

A significant amount of the increase in the wealth income ratio in recent decades is due to an increase in the value of land. We present a series of models that explain why land prices may have increased. These models help us understand the increase in both the wealth income ratio and wealth...

This paper extends the standard life cycle model to a world in which there are also capitalists. We obtain simple formulae describing the equilibrium fraction of wealth held by life-cycle savers. Using these formulae, we ascertain the effects of tax policy or changes in the parameters of the...

This paper investigates the determination of the equilibrium distribution of income and wealth among individuals within a simple equilibrium growth model, where there is consistency between the movements of aggregate variables and the savings, bequest, and reproduction behavior of individuals....

The paper identifies, and then resolves, a number of seeming puzzles in a newly identified set of stylized facts entailing movements in factor returns and shares and the wealth-income ratio. Standard data on savings cannot be reconciled with the increase in the wealth-income ratio: there is a...

Inequality is one of the main challenges posed by the proliferation of artificial intelligence (AI) and other forms of worker-replacing technological progress. This paper provides a taxonomy of the associated economic issues: First, we discuss the general conditions under which new technologies...
