In International Relations the canonical model of inter-estate interactions is a one-shot security competition game. The model has the structure of a prisoners dilemma, which results in an equilibrium with two sources of inefficiency: excessive arming and possibly the destruction associated with...

We propose an overlapping-generations model in which established researchers evaluate the research of new researchers. All researchers are differentially endowed with equally desirable research characteristics and belong to two groups, M or F, which have identical ex-ante productivity...

We compare how well agents aggregate information in two repeated social learning environments. In the first setting agents have access to a public data set. In the second they have access to the same data, and also to the past actions of others. Despite the fact that actions contain no...

The experimental literature on repeated games has largely focused on settings where players discount the future identically. In applications, however, interactions often occur between players whose time preferences differ. We study experimentally the effects of discounting differentials in...

Worldwide, dependency ratios are forecast to increase dramatically in the next 50 years. A great deal of attention has been devoted to understanding the changes in fiscal policies that must' take place to accommodate these changes. In contrast, less effort has been concentrated on studying the...

This paper develops a theory of intergenerational exchange for generations that are either selfish or have non-dynastic altruism. The main building blocks of the theory are forward and backward intergenerational goods (FIGs and BIGs) and the relationship between them. A FIG is a transfer from...

This paper develops, calibrates, and simulates a dynamic 88-period OLG model to study the intergenerational transmission of U.S. wealth inequality via bequests. The model features marriage, realistic fertility patterns, random death, assortative mating based on skills, heterogeneous skill...

As the U.S. population ages, the growing retiree-worker ratio increases the burden of public retirement systems. Is it efficient to maintain a defined benefit social security system? Should PAYGO benefits be reduced and private retirement savings be encouraged? The paper examines these questions...

In a static setup, migration of unskilled labor may be resisted by the entire native-born population because, being relatively low earners, migrants are net beneficiaries of the fiscal system. However, the paper shows that with a pay-as-you-go pension, an important pillar of the welfare state,...

This paper develops a tractable stochastic overlapping generations model to analyze the equilibrium equity premium and growth rate of the capital stock in the presence of a defined-benefit Social Security system. If the Social Security Trust Fund increases the share of its portfolio held in...
