Nonparametric Identification of Incomplete Information Discrete Games with Non-equilibrium Behaviors
This paper jointly relaxes two assumptions in the literature that estimates games. These two assumptions are the parametric restriction on the model primitives and the restriction of equilibrium behaviors. Without imposing the above two assumptions, this paper identifies the primitives of the game. -
Expectation-Driven Term Structure of Equity and Bond Yields
Recent findings on the term structure of equity and bond yields pose serious challenges to existing models of equilibrium asset pricing. This paper presents a new equilibrium model of subjective expectations to explain the joint historical dynamics of equity and bond yields (and their yield spreads). -
More Than Words: Fed Chairs’ Communication During Congressional Testimonies
We measure soft information contained in the congressional testimonies of U.S. Federal Reserve Chairs and analyze its effect on financial markets. Increases in the Chair’s text-, voice-, or face-emotion indices during these testimonies generally raise stock prices and lower their volatility. -
Asymmetric Systemic Risk
Bank regulation presumes risks spill over more easily from large banks to the banking system than vice versa. Interestingly, we observe this is not the case. We find that the capacity to transmit risk is larger in the system-to-bank direction, leading to an increased default risk. -
Exports and the Exchange Rate: A General Equilibrium Perspective
How do a country’s exports change when its currency depreciates? Does it matter which forces drive the exchange rate deprecation in the first place? We find that this relationship varies greatly depending on what drives exchange rate movements, and we conclude that the direct relationship between the exchange rate and exports is weak for Canada. -
What COVID-19 May Leave Behind: Technology-Related Job Postings in Canada
COVID-19 affects technology adoption: online job postings for technology-related occupations fall less during pandemic lockdowns and pick up faster during reopenings than postings for more traditional occupations. -
Addictive Platforms
We study competition for consumer attention, in which platforms can sacrifice service quality for attention. A platform can choose the “addictiveness” of its service. -
Equilibrium in Two-Sided Markets for Payments: Consumer Awareness and the Welfare Cost of the Interchange Fee
We construct and estimate a structural two-stage model of equilibrium in a market for payments in order to quantify the network externalities and identify the main determinants of consumer and merchant decisions. -
Job Ladder and Business Cycles
During downturns, workers get stuck in low-productivity jobs and wages remain stagnant. I build an heterogenous agent incomplete market model with a full job ladder that accounts for these facts. An adverse financial shock calibrated to the US Great Recession replicates the period’s slow recovery and missing disinflation.
