This paper discusses the use of optimization software to solve an optimal control problem arising in the modeling of technology transition. We set up a series of increasingly complex models with such features as learning-by-doing, adjustment cost, and capital investment. The models are written...

Abstract I estimate a return distribution of an equity index from equity index option prices. I evaluate nonparametrically the option price function and a state price density at each 1-year return. Based on a model for dynamics of consumption growth and dividend growth, a real-world probability...

Asset pricing models have largely overlooked the role of labor income dynamics despite it representing two thirds of disposal income. In this paper, we solve a general equilibrium model which can both rationalize important feature of labor markets as well as financial markets. To this end, we...

We study the quantitative properties of constrained e¢ cient allocations in an environ- ment where risk sharing is limited by the presence of private information. We consider a life cycle version of a standard Mirrlees economy where shocks to labor productiv- ity have a component that is public...

This paper analyzes the equilibrium effects of investment commitment on asset prices when the representative consumer has Epstein-Zin utility. Investment commitment captures the idea that long-term investment projects require not only current expenditures but also commitment to future...

We study how the presence of non-exclusive contracts limits the amount of insurance provided in a decentralized economy. We consider a dynamic Mirrleesian economy in which agents are privately informed about idiosyncratic labor productivity shocks. Agents sign privately observable insurance...

I estimate a return distribution of an equity index from equity index option prices. I evaluate nonparametrically the option price function and a state price density at each 1-year return. Based on a model for dynamics of consumption growth and dividend growth, a real-world probability density...

This paper provides new evidence on the failure of the Q-theory of investment. The Q-theory implies the state-by-state equivalence of stock and investment returns---an important implication of many asset pricing models. Using aggregate data, I find there exists a realistic parameterization of...
