The authors’ dynamic equilibrium model guides their quantitative investigation of the major determinants of property-crime patterns in the U.S. The model is capable of reproducing the drop in property crime that occurred between 1980 and 1996. The most important influences on the decline are a...

Latin American countries have long exhibited low levels of saving rates when compared to other countries in relatively similar stages of economic development (e.g., Asian economies). Motivated by this fact, this paper examines the time path of the saving rates between 1970 and 2010 in three...

We develop an applied general equilibrium model to examine the optimal social security replacement rate and the welfare benefits associated with it. Our setup consists of overlapping generations of 65-period lived individuals facing mortality risk and individual income risk. Private credit...

Despite much work, economists have not been able to quantitatively account for the differences in the Japanese and U.S. saving rates after World War II. In this paper, we show that the use of actual Japanese total factor productivity growth rates in a standard growth model generates saving rates...

The aging of the populations in the OECD countries has prompted various calls for reforming the existing pay-as-you-go (PAYG) pension systems. Currently, there is renewed discussion in the United States about partial privatization where a fraction of the social security payroll tax would be...

Low frequency changes in the U.S. current account can be understood in terms of the influence of differences in productivity growth rates across time and across countries using standard growth theory. In particular, the secular decline is primarily driven by the increase in the U.S. TFP growth...

In this paper we study the welfare effects of eliminating social security in a model with two sided altruism where social security provides insurance against lifetime and individual income uncertainty. Our findings indicate that households are able to shift the efficiency gains, generated...

In this paper we analyze the efficacy of seignorage as a tax associated with various monetary arrangements in a computable general equilibrium model. For the economies examined, we find that seignorage tax is not a good one relative to a tax on labor income. If the after-tax real return is –5...

We study a one-sector growth model which is standard except for the presence of an externality in the production function. The set of competitive equilibria is large. It includes constant equilibria, sunspot equilibria, cyclical and chaotic equilibria, and equilibria with deterministic or...

In this paper, we reexamine the question "Why doesn't capital flow from rich to poor countries?" posed, most recently, by Lucas (1990). We build a simple contracting framework where costly intermediation together with an adverse selection problem have quantitatively important effects on capital...
