This paper analyzes the consequences of the change in the presentation mode of economics seminars triggered by the COVID-19 pandemic. The composition of seminar speakers changed significantly. The leading economists gained shares. The share of seminars held by women also increased. The geography of knowledge dissemination shifted significantly as the distance between host and speaker institutions increased on average by 32 percent. The growing inequality in presentations among speakers is correlated with an increase in inequality in terms of citations. The results imply that virtual presentations instead of traveling can decrease gender-specific inequality and increase inequality by productivity in the profession.

This paper shows that idiosyncratic shocks to individual firms can affect growth all over the world, even if shocked firms have no direct foreign connections and no operations abroad. We identify an idiosyncratic shock to a German bank, which caused the bank to cut lending to German borrowers. Multinational parent firms located in Germany became financially constrained. In response, international affiliates of affected parents supported their parent by lending through internal capital markets and became constrained themselves. The real growth of affiliates fell sharply and took three years to fully recover. Though the initial shock only hit the domestic activities of a firm in Germany, the impact in other countries was sizable (for instance, around 0.4 percent of aggregate sales in Austria and the Czech Republic). The findings reveal that idiosyncratic shocks to individual firms influence economic outcomes far beyond firms’ direct scope of operation.

The Quarterly Journal of Economics (QJE) managed by Harvard University and the Journal of Political Economy (JPE) managed by the University of Chicago are two of the top five journals in the economics profession. Drawing on the acknowledgements of about 2,300 publications in the top five journals, this article documents a robust and significant correlation between presenting at Harvard University and publishing in the QJE and between presenting at the University of Chicago and publishing in the JPE. Articles presented at Harvard (Chicago) and published in the QJE (JPE) have a similar impact in terms of citations as other articles published in the QJE (JPE).
