We solve for the equilibrium dynamics of information sharing in a large pop-ulation. Each agent is endowed with signals regarding the likely outcome of arandom variable of common concern. Individuals choose the effort with whichthey search for others from whom they can gather additional...

We study utility indifference pricing of claim streams with intertemporalconsumption and power (CRRA) utilities. We derive explicit formulasfor the derivatives of the utility indifference price with respect toclaims and wealth. The simple structure of these formulas is a reflectionof surprising...

We analyze an equilibrium model in which agents exposed to idiosyncraticrisk can purchase insurance policies in addition to financialassets. The price of an insurance contract depends nonlinearly on theclaims and explicitly contains safety loadings, proportional to variance.We consider random...

We study the exponential utility indifference valuation of a contingentclaim H when asset prices are given by a general semimartingale S. Under mildassumptions on H and S, we prove that a no-arbitrage type condition is fulfilled ifand only if H has a certain representation. In this case, the...

We conduct a laboratory experiment to study whether people in-tuitively use real-option strategies in a dynamic investment setting.The participants were asked to play as an oil manager and make pro-duction decisions in response to a simulated mean-reverting oil price.Using cluster analysis,...

This paper develops a liquidity measure tailored to the foreign exchange (FX) market, quanties the amount of commonality in liquidity across dierent exchange rates, and determines theextent of liquidity risk premiums embedded in FX returns. The new liquidity measure utilizesultra high frequency...

This chapter surveys theoretical research on the long-term performanceof xed-mix investment strategies. These self-nancing strategies rebalancethe portfolio over time so as to keep constant the proportionsof wealth invested in various assets. The main result is that wealthcan be grown from...

We develop a method that allows one to compute incomplete-market equilibria routinely forMarkovian equilibria (when they exist). The main difficulty to be overcome arises from the setof state variables. There are, of course, exogenous state variables driving the economy but, in anincomplete...

We study an equilibrium asset pricing model with several Lucas (1978) trees subject toevent risk, that is, the possibility that trees experience unexpected disasters. We exploit themarket clearing mechanism, in the presence of multiple positive net supply assets, to showthat the implications of...

This paper examines the effects of capital gains taxation on firms’ investmentand financing decisions. We develop a real options model in which the timing ofinvestment, the decision to default, and the firm’s capital structure are endogenouslyand jointly determined. Our analysis demonstrates...
