In this article, we show how to analyze analytically the equilibrium policies and prices in an economy with a stochastic investment opportunity set and incomplete financial markets, when agents have power utility over both intermediate consumption and terminal wealth, and face portfolio...

In this article, our objective is to determine efficient allocations in economies with multiple agents having recursive utility functions. Our main result is to show that in a multiagent economy, the problem of determining efficient allocations can be characterized in terms of a single value...

Our objective is to identify the trading strategy that would allow an investor to take advantage of quot;excessivequot; stock price volatility and quot;sentimentquot; fluctuations. We construct a general-equilibrium model of sentiment. In it, there are two classes of agents and stock prices are...

Our objective is to understand how financial innovation affects investors' optimal asset-allocation decisions and the economic mechanisms through which these decisions influence financial markets, welfare, and wealth inequality. We show that when some investors, such as households, are less...
