In an earlier paper we presented a variable dimension algorithm for solving the linear complementarity problem (LCP). We now extend the class of LCP's that can be solved by this algorithm to include LCP's with copositive plus coefficient matrices. The extension, inspired by Lemke [1965], is...

This paper explores a model of warranties in which moral hazard problems play a key role. The goal is to understand the important characteristics of warranties including their provision of incomplete insurance and the relationship between product quality and coverage. We analyze a model in which...

This paper considers non-contingent trades through either forward markets or simple contracts. The point of the inquiry is to understand the costs and benefits of trades of this nature. We focus on the tradeoff between insurance (a benefit) and the loss of flexibility in decisions (a cost) as...

The Invisibility Hypothesis holds that the job skills of disadvantaged workers are not easily discovered by potential new employers, but that promotion enhances visibility and alleviates this problem. Then, at a competitive labor market equilibrium, firms profit by hiding talented disadvantaged...

The optimal capital income tax is analyzed in the framework of intertemporal efficient taxation. The relation between the zero tax in the long-run and the equality between private and social discount rates is emphasized. The properties of the dynamic second best path described for a specific...

This paper extends the results of Andrews (1984) which considers the problem of robust estimation of location in a model with stationary strong mixing Gaussian parametric distributions. Three neighbourhood systems are considered, each of which contains the Hellinger neighbourhoods used in...

A model is presented which is derived from some observations of Keynes on the nature of capital. The allocation of investment is analyzed in two economies with random demand shocks which are identical except for the types of markets. In the first, the combination of an asset and forward markets...
