Associate Professor of Finance, Saïd Business School, University of Oxford, UK
I am a financial economist interested in how finance interacts with other fields of economics, including industrial organization, labor economics, behavioral economics, monetary economics, and micro-economic theory. Recent projects, categorized below, examine how
(A1) financial constraints, transactions costs, monetary conditions, and heterogeneous beliefs,
(A2) imperfect competition, and
(A3) political economy considerations
affect corporate financial choices, entrepreneurship, firm strategy and market outcomes, as well as central bank behavior.
I also care about how non-standard beliefs (B1) and preferences (B2) affect individual investor behavior and asset prices.
I teach Big Data, Artificial Intelligence, and Machine Learning applications in finance.

Working Papers (by topic)
(A1) Corporate Finance and Security Design
Unionization, Cash, and Leverage uses a regression discontinuity design on unionization elections to identify the causal effect of unionization on firms' financial policies.
(A2) Common Ownership, Firm Behavior, and Market Outcomes
Common Ownership, Competition, and Top Management Incentives (with Miguel Antón, Florian Ederer, and Mireia Giné) shows that managers in more commonly owned industries have reduced incentives to maximize their own firms' value. [Fall 2016 NBER OE] [Slides]
Ultimate Ownership and Bank Competition (with José Azar and Sahil Raina) develops an index of ultimate ownership concentration and relates it to market-level prices of deposit banking products. [2016 NBER SI IO]
(A3) Political Economy of Central Banking & Monetary Economics
(Why) Do Central Banks Care About Their Profits? (with Igor Goncharov and Vasso Ioannidou) shows that central banks care about their profitability, especially when political pressure or career concerns are more pronounced, and when the population is more susceptible to populism and thus perhaps attacks on central bank independence. These findings have implications for the effectiveness and sustainability of non-traditional monetary policy, central bank design, and theoretical modeling in macroeconomics. [Slides] [R&R, Journal of Finance]
(B2) Behavioral Finance and Asset Pricing
Anxiety and Pro-Cyclical Risk Taking with Bayesian Agents (with Thomas Eisenbach) provides an explanation why some people sometimes become overconfident and take excessive risks.
Horizon-dependent Risk Aversion and the Timing and Pricing of Uncertainty (with Marianne Andries and Thomas Eisenbach) reconciles long-run risk models with a downward-sloping term structure of risk prices without requiring a preference for the early or late resolution of uncertainty. [Fall 2014 NBER AP] [R&R, Review of Financial Studies]
The Term Structure of the Price of Variance Risk (with Marianne Andries, Thomas Eisenbach, and Yichuan Wang) finds that the price of variance risk decreases with maturity, and thus helps distinguish between alternative asset pricing models.
