Diskussionspapiere 1937 / 2021
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: ...

Diskussionspapiere 1934 / 2021
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 ...

Diskussionspapiere 1972 / 2021
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 ...

SOEP Brown Bag Seminar
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...

DIW Applied Micro Seminar
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...

The Federal Agency for Cartography and Geodesy (BKG) provides 3D-Building models for Germany. The data come in a City-GML (geographical markup language) format, locating every building throughout Germany and providing information such as its ground plan, height, and the building’s purpose. I will provide an overview on the data, its coverage and limitations, as they are available for...

Sind Daten das neue Gold? Man hat den Eindruck, dass wir alle technischen Finessen ausloten, um an das wertvolle Gut heranzukommen. Was auch immer mit dem Begriff „Daten“ assoziiert wird, scheint diesem Vorhaben Glanz zu verleihen. Entscheidungen, Politik, Management und vieles mehr sollten jetzt „datengesteuert“ sein. Big Data, Machine Learning, Algorithmen und kü...
