I generalize the long-run risks (LRR) model of Bansal and Yaron (2004) by incorporating recursive smooth ambiguity aversion preferences from Klibanoff et al. (2005, 2009) and time-varying ambiguity. Relative to the Bansal-Yaron model, the generalized LRR model is as tractable but more flexible...

How many interest rate hikes is quantitative tightening (QT) equivalent to? In this paper, I examine this question based on the preferred-habitat model in Vayanos and Vila (2021). I define the equivalence between rate hikes and QT such that they both have the same impact on the 10-year yield....

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....

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...

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,...

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...

In this paper, we study the interplay between sovereign risk and global financial risk. We show that a substantial portion of the comovement among sovereign spreads is accounted for by changes in global financial risk. We construct bond-level sovereign spreads for dollar-denominated bonds issued...
