Higher Seminar in Economics | Imposing equilibrium restrictions in the estimation of dynamic discrete games

5/19/2021, 3:30 PM - 4:45 PM
Department of Economics is welcoming you to online seminar with Mathieu Marcoux, Assistant Professor of Economics, Université de Montréal. We study the asymptotic properties of the NPL algorithm treating the iterative procedure as performed in finite samples. We find that there are always samples for which the algorithm fails to converge, and this introduces a selection bias. We also propose a spectral algorithm to compute the NPL estimator. This algorithm satisfies local convergence and avoids the approximation of Jacobian matrices. We present simulation evidence illustrating our theoretical results and the good properties of the spectral algorithm. This is an online seminar which will take place via Zoom.

Higher Seminar in Economics | The Effects of Advertising Disclosure Regulations on Social Media: Evidence From Instagram

5/12/2021, 3:30 PM - 4:45 PM
Department of Economics is welcoming you to online seminar with Daniel Ershov, Toulouse School of Economics. We study the effects of advertising disclosure regulations in social media markets. Using data from a large sample of Instagram influencers in Germany and Spain and a difference-in-differences approach, we empirically evaluate the effects of German disclosure regulations on post content and follower engagement. This is an online seminar which will take place via Zoom.
