Many economic decisions can be described as an option exercise or optimal stopping problem under uncertainty. Motivated by experimental evidence such as the Ellsberg Paradox, we follow Knight (1921) and distinguish risk from uncertainty. To afford this distinction, we adopt the multiple-priors...

This paper analyzes a risk averse entrepreneur's real investment decision under incomplete markets. The entrepreneur smoothes his intertemporal consumption by investing in both a risk-free asset and a risky asset, which allows him to partially hedge against the project cash flow risk. We show...

This paper studies consumption/saving problem under Knightian uncer- tainty in a two period setting. The multiple-priors utility model is adopted. The e®ects of income uncertainty and capital uncertainty on optimal savings are analyzed by deriving closed form solutions.

What is the long-run effect of dividend taxation on aggregate capital accumulation? To address this question, we build a dynamic general equilibrium model in which there is a continuum of firms subject to idiosyncratic productivity shocks. This firm heterogeneity generates a cross-sectional...

Conflicts of interest between insiders (e.g, controlling shareholders) and outsiders (e.g., minority shareholders) are central to the analysis of modern corporation. In an integrated continuous-time contingent claims framework with imperfect corporate governance, we examine a controlling...

In this paper we present a recursive method for the computation of dynamic competitive equilibria in models with heterogeneous agents and market frictions. This method is based on a convergent operator over an expanded set of state variables. The fixed point of this operator defines the set of...
