This paper analyzes how ambiguity affects the tournament outcome and the project selection of a multi-business-unit organization. We consider a tournament model where business unit managers compete against each other for a promotion reward but are ambiguous about how relatively well their skills...

We consider long-run behavior of agents assessing risk in terms of dynamic convex risk measures or, equivalently, utility in terms of dynamic variational preferences in an uncertain setting. By virtue of a robust representation, we show that all uncertainty is revealed in the limit and agents...

This paper studies optimal equity portfolios with long-term horizon under heterogeneous risk aversion levels. We focus on European stocks and empirically show that contemporaneous excess returns of semi-active strategies are negatively associated with market conditions and sentiment. Consistent...

We analyze a continuous-time stochastic control problem that arises in the study of several important issues in financial economics. An agent controls the drift and volatility of a diffusion output process by dynamically selecting one of an arbitrary (but finite) number of projects and the...

We provide a preference-based rationale for endogenous overconfidence. Horizon-dependent risk aversion, combined with a possibility to forget, can generate overconfidence and excessive risk taking in equilibrium. An "anxiety prone" agent, who is more risk-averse to imminent than to distant...

We study how managers respond to hurricane events when their firms are located in the neighborhood of the disaster area. We find that the sudden shock to the perceived liquidity risk leads managers to increase corporate cash holdings and to express more concerns about hurricane risk in...

We explore a satisficing approach (Simon, 1955) to measure risk preference, which suggests cognitive limitations to decision making. In an experiment, subjects invest in a portfolio that contains a risk-free bond and a risky asset which has high or low return states with equal probability. The...
