An increasing body of empirical evidence is documenting trends toward rising concentration, profits, and markups in many industries around the world since the 1980s. Two major criticisms of these studies is that concentration and market shares are poorly measured at the national industry level while firm level revenues are a poor indicator of product sales. We use a novel database that identifies over ...
Welfare is traditionally understood through social security decommodifying labor markets or social investment policies. In the domain of housing, however, welfare for homeowners is largely hidden in the tax codes’ fiscal exemptions. Based on a content analysis of legislation, this paper introduces a novel yearly database of 37 countries between 1910 and 2020 to uncover the “hidden welfare state” of ...
We study the relationship between crowding and performance in the active mutual fund industry. We construct a fund-specific measure of crowding using the equity holdings overlap of 17,364 global funds. Funds in the top decile of crowding underperform passive benchmark funds by 1.4% per year. The impact of crowding on performance cannot be attributed to diseconomies of scale. We explore several mechanisms: ...
We investigate patterns in common ownership networks between firms that are active in the U.S. pharmaceutical industry for the period 2004–2014. Our main findings are that “brand firms”—that is, firms that have research and development capabilities and launch new drugs—exhibit relatively dense common ownership networks with each other that further increase significantly in density over time, whereas ...
This paper analyzes two dimensions of factors of political trust in Russia. The first dimension is the target dimension (sociotropic vs. egocentric), the second dimension is the time dimension (retrospective vs. perspective). The study is based on the microdata of 2016 Life in Transition Survey (LiTS) of the European Bank for Reconstruction and Development. We find a robust evidence in favor of the ...
This is an online seminar using Webex. You will receive the login data with the invitation to the talk. Abstract: There is an ongoing debate both in academia and in policy circles about the effects of takeovers of small, young firms by large incumbents in innovative industries. Many argue that such takeovers are anticompetitive and harm innovation by killing off nascent competition....
On 2 June 2020 DG Competition of the European Commission published several support studies on the retrospective evaluation of State aid rules. This “Fitness check” will serve as a basis for future Commission’s decisions about whether to further prolong or update the rules expiring in 2020. The consortium of DIW Berlin, Lear, Sheppard Mullin and UEA Consulting under the leadership ...
In this study we estimate the hidden cost of restrictive migration policies and highlight the need for health-related support among refugees. The traumatic events asylum seekers experience at origin due to exposure to violent conflict and during the journey to the EU may have lasting negative effects on their economic and social integration in the destination country. We hypothesize that...
Summary: This talk will provide a survey of several papers on the theory and practice of experimental design. I will compare different objectives (estimator precision, outcomes of participants, informing policy choice to maximize average outcomes, and informing policy choice to maximize utilitarian welfare), and their implications for experimental design. I will consider heuristic...
