The development of algorithmic pricing has led to a growing market in the supply of pricing algorithms by data analytic companies. While there is an efficiency rationale for a firm outsourcing its pricing decision, anticompetitive concerns have been expressed when competitors in a market adopt a...

Significant progress reconciling economic activities with a stable climate requires radical and rapid technological change in multiple sectors. Here, we study the case of the automotive industry's transition to electric vehicles, which involved choosing between two different technologies: Fuel Cell...

It was established in the 90's by Pemantle, Brandière and Duflo that stochastic gradient descent (SGD) escapes saddle points of smooth function. Knowing that critical points of a typical/generic smooth function are either local minima or saddle points, we can interpret this result as a generic...

We study the quantitative stability of the mapping that to a measure associates its pushforward measure by a fixed (non-smooth) optimal transport map. We exhibit a tight Hölder-behavior for this operation under minimal assumptions. Our proof essentially relies on a new bound that quantifies the...

Empirical research typically involves a robustness-efficiency tradeoff. A researcher seeking to estimate a scalar parameter can invoke strong assumptions to motivate a restricted estimator that is precise but may be heavily biased, or they can relax some of these assumptions to motivate a more...
