We examine the impact of incomplete risk-sharing on growth and welfare. The source of market incompleteness in our economy is private information: a household's idiosyncratic productivity shock is not observable by others. Risk-sharing between households occurs through long- term contracts with...

We develop a model of costly technology adoption where the cost is irrecoverable and fixed. Households must decide when to switch from an existing technology to a new, more productive technology.

We study the impact of a minimum consumption requirement on the rate of economic growth and the evolution of wealth distribution.

We conduct Monte Carlo experiments to examine whether the Hansen and Jagannathan (1991) bound is a useful device for evaluating asset pricing models. Specifically, we use recently developed statistical tests, which are based on a 'distance' between the model and the Hansen-Jagannathan bound, to...

In this paper, the conventional test of the Sharpe-Lintner version of the Capital Asset Pricing Model (CAPM) are reconsidered. The CAPM is formulated as a Seemingly Unrelated Regression (SUR) system with an adding-up restriction. A statistical framework for conducting the conventional tests is...

This paper models a family business as a closely-held technology that cannot be contracted upon. Each generation can either bequeath the business to the next generation, or it could sell it through a financial intermediary and bequeath the revenue.

We explore how the introduction of habit preferences into the simple intertemporal consumption-based capital asset pricing model "solves" the equity premium and risk-free rate puzzles. Our exploration employs spectral utility functions that decompose agents' preferences for consumption...

In this paper, we examine the robust Wald test statistic for SUR systems with adding up restrictions where the same explanatory variables are present in all equations and where heteroskedasticity and/or autocorrelation of unknown forms may be present. For this case, the coefficients are usually...
