We study a pure exchange economy under incomplete markets where households have heterogeneous homothetic recursive preferences and lending and borrowing are precluded. We fully characterize the properties of the efficient allocations and the equilibrium asset price. The ownership distribution...

We study the consumption-portfolio problem with realized capital gain taxation. The distinguishing feature of our analysis is that we impose on the model an important element of the tax code that has received little attention in the academic literature: the limited use of capital losses....

We consider the impact of "large" changes in asset prices on intra-market correlations in domestic and international markets. Assuming normally distributed asset returns, we show that the absolute magnitude of the correlation, conditional on a change is greater than or equal to a given absolute...

In this paper, we study the consumption-portfolio problem of an investor who faces realized capital gain taxes in a two stock setting with short sales. The investor finances consumption and a time of death bequest by trading in a money market and two stocks that he can short sell subject to...

We present a class of multi-factor stochastic models for energy futures prices, similar to the interest rate futures models recently formulated by Heath. We do not postulate directly the risk-neutral processes followed by futures prices, but define energy futures prices in terms of a spot price,...

This paper develops a structural model that determines default spreads in a setting where the debt's collateral is endogenously determined by the borrower's investment choice, and a demand variable with permanent and temporary components. We also consider the possibility that the borrower cannot...

In the energy markets, in particular the electricity and natural gas markets, many contracts incorporate flexibility-of-delivery options known as "swing" or "take-or-pay" options. Subject to daily as well as periodic constraints, these contracts permit the option holder to repeatedly exercise...

We present a numerical algorithm for pricing derivatives on electricity prices. The algorithm is based on approximating the generator of the underlying price process on a lattice of prices, resulting in an approximation of the stochastic process by a continuous time Markov chain. We numerically...
