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....

This paper empirically analyzes how exchange rate policy affects the issuance and pricing of international bonds for developing countries. We find that countries with less flexible exchange rate regimes pay higher sovereign bond spreads and are less likely to issue bonds. Quantitatively,...

This paper offers an ambiguity-based interpretation of variance premium --- the difference between risk-neutral and objective expectations of market return variance --- as a compounding effect of both belief distortion and variance differential regarding the uncertain economic regimes. Our...

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,...

I construct a dynamic rational expectations equilibrium model to unify open-end fund flows and closed-end fund discounts based on managerial ability. The model features both endogenous portfolio management of fund managers and endogenous fund purchase decisions of fund investors. The fully...

We document stylized facts about China's recent exchange rate policy for its currency, the Renminbi (RMB). Our empirical findings suggest that a "two-pillar policy" is in place, aiming to balance RMB index stability and exchange rate flexibility. We then develop a tractable no-arbitrage model of...

We generalize the long-run risks (LRR) model in Bansal and Yaron (2004) by incorporating the recursive smooth ambiguity aversion preferences of Klibanoff, Marinacci, and Mukerji (2005, 2009) and time-varying ambiguity. Relative to the Bansal-Yaron model, the generalized LRR model remains...
