To offer a possible interpretation for recent empirical findings on earnings growth, this paper constructs a simple model with endogenous human capital investment, a distribution of natural abilities, and unbiased technological progress. The model predicts that in the long run, average earnings...

The evidence continues to mount. As our industrial economy continues to dump large amounts of carbon into the atmosphere, we are affecting the atmospheric chemistry of the global climate. This has led prominent physicist and climate scientist James Hansen to reach the “startling conclusion”...

This paper proposes and analyzes a Social Security reform in which individuals no longer face the OASI payroll tax after, say, age 54 or a career of 34 years, and their subsequent earnings have no bearing on their benefits. We first estimate parameters of a life-cycle model. Our specification...

We introduce a tractable model of post-retirement saving behavior in which households have a precautionary motive arising from uninsured health status risks. The model distinguishes between annuitized and non-annuitized wealth, emphasizes the importance of asset composition in determining...

The literature evaluating tax changes within an intertemporal general equilibrium framework subdivides into representative agent and overlapping generations formulations. Papers in the former class have developed techniques analogous to those routine for static analyses. The author shows that...

This article constructs a decentralized growth model with two production sectors, one having competitive firms and the other oligopolists. Since capitalized pure profits for the latter sector constitute an asset which household savings must finance, we show that imperfect competition can reduce...
