Do Science Kardashians Get Citation Premium? Self‐Fulfilling Effects of Social Media on Scientific Impact
We analyze whether the visibility of scientists on social media affects the number of academic citations. We use the global COVID‐19 pandemic as a quasinatural experiment that exogenously increased public attention and the demand for expertise. Using publications on COVID‐related topics by social media stars and their coauthors prior to the outbreak of the pandemic, we find that social media stars' pre‐COVID‐era papers received about – more citat…
Women in STEM graduate education
Are public policies effective in enhancing gender balance in science, technology, engineering, and mathematics (STEM) graduate education? Although the literature is rich in studies that prescribe micro‐level interventions to promote gender balance in specific STEM areas or institutions, there are surprisingly few studies that quantitatively evaluate existing macro‐level policies. Using Germany's Excellence Initiative as an event study, I analyse …
Leadership in Scholarship
Academic journals disseminate new knowledge and therefore can influence the direction and composition of ongoing research by choosing what to publish. We study the change in the topic structure of papers published in the American Economic Review (AER) after the appointments of editors and coeditors of the AER between 1985 and 2011 using a textual analysis of accepted publications. The change due to the appointment of new AER editors, we find, is …
German-Jewish Scholars in Turkish Exile
This paper documents the migration experiences of German-Jewish scholars who fled from the Nazi regime and sought refuge in Turkey in 1930s. Reflecting on the historical narratives originating from the memoirs of renowned scientists, their relatives, or their Turkish colleagues –e.g., a 1986 interview with renowned economist Fritz Neumark, memoirs of Klaus Eckstein --son of famous pediatrician and public health expert Albert Eckstein-- and narrat…
The Role of Outgroup Network in the Choice of Migration Destination
We analyse the association between cultural contact and international migration decision drawing on the inter-group contact hypothesis. Using data on Turkish migrant stock in 22 countries and immigration from these countries to Turkey between 2000 and 2015, we find a strong association between the Turkish community's size and migration flow of host country nationals to Turkey. Our results are robust to country-specific and year-specific effects a…
Ebola and State Legitimacy
We exploit the West African Ebola epidemic as an event that necessitated the provision of a common-interest public good, Ebola control measures, to empirically investigate the effect of public good provision on state legitimacy. Our results show that state legitimacy, measured by trust in government authorities, increased with exposure to the epidemic. We argue, supported by results from SMS-message-based surveys, that a potentially important cha…
No place like home
We set up an opinion diffusion model with a local opinion leader, and using simulations we show the possibility of driving a significant wedge between the opinions of two groups that exhibit homophily although individuals are highly conformist. There exists an opinion gap between the group to which the opinion leader belongs and the other group. This opinion gap increases according to the relative size of the residence community. We show empirica…
The Research Productivity of New PhDs in Economics
We study the research productivity of new graduates from North American PhD programs in economics from 1986 to 2000. We find that research productivity drops off very quickly with class rank at all departments, and that the rank of the graduate departments themselves provides a surprisingly poor prediction of future research success. For example, at the top ten departments as a group, the median graduate has fewer than 0.03 American Economic Revi…
