This paper explores the equilibrium correspondence of a dynamic quality ladder model with entry and exit using the homotopy method. The homotopy method facilitates exploring the equilibrium correspondence in a systematic fashion; it is ideally suited for investigating the economic phenomena that...

This paper shows in an economy with search on credit and labor markets that a financial multiplier raises the elasticity of labor market tightness to productivity shocks, and that this multiplier is an increasing function of total financial costs in the economy. Under a credit market...

The propagation properties of the standard search and matching model of equilibrium unemployment are significantly altered when vacancy costs require some external financing on frictional credit markets. The latter induce variation in the shadow cost of external funds of the cycle that greatly...

This paper provides a step-by-step guide to solving dynamic stochastic games using the homotopy method. The homotopy method facilitates exploring the equilibrium correspondence in a systematic fashion; it is especially useful in games that have multiple equilibria. We discuss the theory of the...

Learning-by-doing and organizational forgetting have been shown to be important in a variety of industrial settings. This paper provides a general model of dynamic competition that accounts for these economic fundamentals and shows how they shape industry structure and dynamics. Previously...

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...
