An Anatomy of Firms’ Political Speech
We study the distribution of political speech across U.S. firms. We develop a measure of political engagement based on firms’ communications (earning calls, regulatory filings, and social media) by training a large language model to identify statements that contain political opinions. Using these data, we document five facts about firms’ political engagement. -
Markups and Inflation in Oligopolistic Markets: Evidence from Wholesale Price Data
We study how the interaction of market power and nominal price rigidity influences inflation dynamics. We find that pass-through declines with price stickiness when markets are concentrated, which implies a lower slope of the New Keynesian Phillips curve. -
Decomposing Systemic Risk: The Roles of Contagion and Common Exposures
We examine systemic risks within the Canadian banking sector, decomposing them into three contribution channels: contagion, common exposures, and idiosyncratic risk. Through a structural model, we dissect how interbank relationships and market conditions contribute to systemic risk, providing new insights for financial stability. -
Pricing behaviour and inflation during the COVID-19 pandemic: Insights from consumer prices microdata
Using the microdata underlying the Canadian consumer price index, we study how often and by how much firms changed their prices during the COVID-19 pandemic. We find that the surge in inflation was mainly associated with retailers raising prices much more often than before. We also find that more recently, corporate price-setting behaviour appears to be approaching pre-pandemic norms. -
The Role of Long-Term Contracting in Business Lending
This paper examines inefficiencies arising from a lack of long-term contracting in small business lending in China. -
Market structure of cryptoasset exchanges: Introduction, challenges and emerging trends
This paper provides an overview of cryptoasset exchanges. We contrast their design with exchanges in traditional financial markets and discuss emerging regulatory trends and innovations aimed at solving the problems cryptoasset exchanges face. -
Testing Collusion and Cooperation in Binary Choice Games
This paper studies the testable implication of players’ collusive or cooperative behaviour in a binary choice game with complete information. I illustrate the implementation of this test by revisiting the entry game between Walmart and Kmart. -
Digitalization: Prices of Goods and Services
This paper outlines and assesses the various channels through which digitalization can affect prices of goods and services. -
Intermediary Market Power and Capital Constraints
We examine how intermediary capitalization affects asset prices in a framework that allows for intermediary market power. We introduce a model in which capital-constrained intermediaries buy or trade an asset in an imperfectly competitive market, and we show that weaker capital constraints lead to both higher prices and intermediary markups.
