A derivative asset is a security whose payoff is entirely determined by the prices of one or more underlying securities. Call and put options on stocks are simple examples. Since 1973, when Black and Scholes published their path-breaking option price formula, a rapidly growing literature has...

Many practitioners point out that the speculative profits of institutional traders are eroded by the difficulty in gauging the price impact of their trades. In this paper, we develop a model of strategic trading where speculators face such a dilemma because of incomplete information about...

We develop a dynamic stochastic equilibrium model of two locations within a city where heterogeneous households make joint location and tenure mode decisions. To investigate the effect of homeownership on equilibrium prices and allocations, we compare the response of this model economy to a...

Several authors have derived closed-form option prices in models where the underlying financial variable follows a diffusion process with the following two charactieristics: (i) the process has natural upper and lower boundaries; (ii) its diffusion coefficient is quadratic in the current value...

This paper presents a dynamic theory of housing market fluctuations. It develops a life-cycle model where households are heterogeneous with respect to income and preferences, and mortgage lending is restricted by a down-payment requirement. the market interaction of young credit-constrained...

This paper presents a first step towards a new theory of housing market fluctuations. We develop a life-cycle model where agents face credit constraints and their housing consumption is restricted to a discrete set of possibilities. The market interaction of young credit constrained agents...

We investigate how business ties with portfolio firms influence mutual funds’ proxy voting using a comprehensive dataset spanning 2003 to 2011. In sharp contrast to the prior literature, we show that the proxy voting of mutual funds is significantly influenced by their business ties with...

This paper shows that product market competition has two opposing effects on asset returns. The first relates to the procyclical nature of the value destruction from expansion of competitors, which lowers exposure to systematic risk in more competitive industries. The second is related to the...

We develop a dynamic model of liquidity provision, in which hedgers can trade multiple risky assets with arbitrageurs. We compute the equilibrium in closed form when arbitrageurs’ utility over consumption is logarithmic or risk-neutral with a non-negativity constraint. Liquidity is increasing...

We provide a theoretical framework to study blockholder activism by funds who com- pete for investor ?ow. In our model, activists are intrinsically able to raise the value of target ?rms through monitoring. Competition for investor ?ow induces them to enhance the returns generated by monitoring...
