Uncertainty has qualitatively different implications than risk in studying executive incentives. We study the interplay between profitability uncertainty and moral hazard, where profitability is multiplicative with managerial effort. Investors who face greater uncertainty desire faster learning,...

We propose a unified model of limited market integration, asset-price determination, leveraging, and contagion. Investors and firms are located on a circle, and access to markets involves participation costs that increase with distance. Despite the ex-ante symmetry of investors, their strategies...

My dissertation aims at understanding the economic force behind the success of long-run consumption-based asset pricing models, it consists of three chapters. It also provides us a new approach to test consumption-based asset pricing models. Chapter one provides a brief summary of the...

This paper introduces profitability uncertainty into an infinite-horizon variation of the classic Holmstrom and Milgrom (1987) model, and studies optimal dynamic contracting with endogenous learning. The agent's potential belief manipulation leads to the hidden information problem, which makes...

expected returns to the cyclical fluctuations in consumption. The models by Bansal and Yaron (2004) and Panageas and Yu (2005) provide examples of such models.

Online appendix for the Review of Economic Dynamics article

We introduce uncertainty into Holmstrom and Milgrom (1987) to study optimal long-term contracting with learning. In a dynamic relationship, the agent's shirking not only reduces current performance but also increases the agent's information rent due to the persistent belief manipulation effect....

The size and style of referencing for a large sample of 60 years of publications of the Cowles Foundation are examined. The influence of computerization is considered. Self-referencing is noted and some observations are made on the costs and distribution of research papers.
