We revisit the group size paradox in a simple model where two groups of different sizes compete for a prize exhibiting a varying degree of rivalry and where group effort is given by a CES function of individual efforts. We show that the larger group can be more successful than the smaller group if...

Nowadays, a common practice to forecast integrated variance is to do simple OLS auto-regressions of the observed realized variance data. However, non-parametric estimates of the tail index of this realized variance process reveal that its second moment is possibly unbounded. In this case, the...

This paper provides a quantitative analysis of the effects of the law and economics movement on the U.S. judiciary using the available universe of opinions in U.S. Circuit Courts and 1 million District Court criminal sentencing decisions linked to judge identity. We estimate the effect of...

In empirical studies about strategic interactions, often it is assumed that all the parameters of interest are commonly known by the players of the interactions (and only the analyst does not know them). However, in some cases, such a ``complete information'' assumption may not seem so reasonable....

The fraction of women in economics has grown significantly over the last forty years. In spite of this, the differences in research output between men and women are large and persistent. These output differences are related to differences in the co-authorship networks of men and women: women have...

We study the implications of consumer switching costs on prices when price adjustments are costly. We develop a dynamic pricing model in a multiproduct oligopoly setting, in which consumers exhibit inertia in their choices and firms face costly price adjustments. Motivated by the empirical...

This paper is devoted to the non-asymptotic control of the mean-squared error for the Ruppert-Polyak stochastic averaged gradient descent introduced in the seminal contributions of [Rup88] and [PJ92]. In our main results, we establish non-asymptotic tight bounds (optimal with respect to the Cramer-...
