Price freezes on essential energy commodities are widely used to curb inflation expectations and protect low-income households from price volatility. Yet these interventions often become persistent subsidies that distort markets and hinder climate policy goals. We study this dynamic by analyzing...

The relationship between competition and innovation is difficult to disentangle, as exogenous variation in market structure is rare. The 1952 breakup of Germany’s leading chemical company, IG Farben, represents such a disruption. After the Second World War, the Allies occupying Germany imposed the...

As platforms collect more user data, they can tailor algorithms to better match users. At the same time, on matching platforms, users pay to be matched by the platform, while the platform makes money as long as it does not match them. This paper analyzes the matching rule of a profit-maximizing...

In this talk we introduce the semi-discrete optimal transport (OT) problem with entropic regularization. We characterize the solution using a governing, well-posed ordinary differential equation (ODE). This naturally yields an algorithm to solve the problem numerically, which turns out to be...

We document pervasive frictions in news consumption on social media, and test interventions designed to address them through a large field experiment on Facebook. We find that a simple, platform-integrated interface prompting active choice significantly and persistently reduces the partisan slant...

This paper highlights the importance of finding all roots for the Continuously Updating Generalized Method of Moments (CU-GMM) estimator and Likelihood Ratio (LR)-based tests. Traditional numerical optimization methods often fail to locate global minima due to the non-convexity of objective...

With the monetary policy lower bound a re-emerging concern in some locations, we present new insights on the impact of negative policy rates. We develop a new theoretical model to match the empirical evidence on their effects. It features a heterogeneous, oligopolistic banking sector where loan...
