A model of optimal accumulation of capital and portfolio choice over an infinite horizon in continuous time is formulated in which the vector process representing returns to investments is a general semimartingale. Methods of stochastic calculus and calculus of variations are used to obtain...

We develop an incomplete contract model to analyze the enlargement strategy of a club. An applicant is characterized by his wealth and the degree of conformity with the club standard. The club gains only from a fully reformed new members, but reforms is costly. The club chooses between early...

This paper considers a two country economy similar to that in Obstfeld and Rogoff (1995). We build on their model by distinguishing between sticky retail prices, sticky wholesale prices and sticky wages. We find that conclusions about whether monetary shocks lead to exchange rate overshooting...

This paper considers optimal monetary in the context of the central bank adopting a asymmetric objective function. We exploit a procedure, due to Varian and Zellner, to derive policies under commitment and discretion. Our results show that under asymmetric preferences, many of the extant results...

The purpose of this paper is to quantify and test for the existence of inventory control and asymmetric information in stock market price quotes, extending the time series work of Hasbrouck (1988,1991) to the institutional setting of the London Stock Exchange. In contrast to the NYSE work our...

We propose a procedure for estimating the critical values of the Klecan, McFadden, and McFadden (1990) test for first and second order stochastic dominance in the general k-prospect case. Our method is based on subsampling bootstrap. We show that the resulting test is consistent. We allow for...

We study the dynamics of the spread between US corporate and Treasury bonds. We focus on Aaa and Baa corporate yield indices and estimate nonparametrically the dynamics of the spreads assuming that they follow a univariate diffusion process. Using technique developed for interest rate processes...

Traditional empirical strategies for studying convergence - more generally, the dynamics and determinants of economic growth, can be misleading if important, underlying permanent or growth components are stochastically time-varying. This paper documents the degree to which this instability...

This paper surveys asset allocation methods that extend the traditional approach. An important feature of the the traditional approach is that measures the risk and return tradeoff in terms of mean and variance of final wealth. However, there are also other important features that are not always...

Recent imperfect capital market theories predict the presence of asymmetries in the variation of small and large firms risk over the economic cycle. Small firms with little collateral should be more strongly affected by tighter credit market conditions in a recession state than large, better...
