This paper develops a tractable overlapping generations model that is useful for analyzing both the short and long run impact of fiscal policy and social security. It modifies the Blanchard (1985)/Weil (1987) framework to allow for life/cycle behavior. This is accomplished by introducing random...

Linear RE models typically possess a multiplicity of solutions. Consider, however, the requirement that the solution coefficients must not be infinitely discontinuous in the model's structural parameters. In particular, we require that the solutions should be continuous in the limit as those...

Consider a rational expectations (RE) model that includes a relationship between variables x_t and z_t+1. To be considered structural and potentially useful as a guide to actual behavior, this model must specify whether x_t is influenced by the expectation at t of z_t+1 or, alternatively, that z_t+1...

Recent mainstream monetary policy analysis focuses on rational expectation solutions that are uniquely stable. A number of recent studies have examined the question of whether typical New Keynesian (NK) models, with policy rules that satisfy the Taylor principle, also exhibit solutions with...

What determines the technology that a country adopts? While many factors affect technological adoption, the efficiency of the country's financial system may also play a significant role. To address this question, a dynamic contract model is embedded into a general equilibrium setting with...

Intangible capital is an important factor of production in modern economies that is generally neglected in business cycle analyses. We demonstrate that intangible capital can have a substantial impact on business cycle dynamics, especially if the intangible is complementary with production...

We study the wealth distribution in Bewley economies with idiosyncratic capital income risk. We show analytically that under rather general conditions on the stochastic structure of the economy, a unique ergodic distribution of wealth displays a fat tail; more precisely, a Pareto distribution in...

James A. Schmitz (2005) documents, in a well-known case study, a dramatic rise in productivity in the U.S. and Canadian iron-ore industry following an increase in competition from Brazil. Prior to the increased competition, the industry was not competitive. Surplus in profits was divided between...

This paper provides estimates of the economic impact of non-communicable diseases (NCDs) in China and India for the period 2012-2030. Our estimates are derived using WHO's EPIC model of economic growth, which focuses on the negative effects of NCDs on labor supply and capital accumulation. We...

In recent decades, advanced economies have experienced low and stable inflation and long periods of liquidity trap. We construct an alternative business-cycle model capturing these two features by adding two assumptions to a money-in-the-utility-function model: the labor market is subject to...
