The Aggregate Effects of the Decline of Disruptive Innovation

Abstract
This paper proposes a model that explains both recently documented facts about the decline of disruptive innovation and the decline in productivity growth as the result of large firms trying to monopolize technologies by poaching inventors from disruptive activities. To come to this conclusion, the paper builds an endogenous growth model with inventor labor markets on which firms can interact strategically. To inform this model, I perform an event study of the effect of disruptive inventions on their technology fields using PATSTAT (1980-2010). I document that technology classes without disruption slowly trend towards incrementalism and that after a disruption, more patents get registered and research becomes less incremental.

Safety Net or Helping Hand? The Effect of Job Search Assistance and Compensation on Displaced Workers

Nr. 18,

Abstract
We provide the first systematic evidence on the effectiveness of a contested policy in Germany to help displaced workers. So-called “transfer companies” (Transfergesellschaften) employ displaced workers for a fixed period, during which time workers are provided with job-search assistance and are paid a wage which is a substantial fraction of their pre-displacement wage. Using rich and accurate data on workers’ employment patterns before and after displacement, we compare the earnings and employment outcomes of displaced workers who entered transfer companies with those that did not. Workers can choose whether or not to accept a position in a transfer company, and therefore we use the availability of a transfer company at the establishment level as an IV in a model of one-sided compliance. Using an event study, we find that workers who enter a transfer company have significantly worse post-displacement outcomes, but we show that this is likely to be the result of negative selection: workers who lack good outside opportunities are more likely to choose to enter the transfer company. In contrast, ITT and IV estimates indicate that the use of a transfer company has a positive and significant effect on employment rates five years after job loss, but no significant effect on earnings. In addition, the transfer company provides significant additional compensation to displaced workers in the first 12 months after job loss.

Stadtfrust und Landlust? Über regionale Präferenzen von hochqualifizierten Individuen

Abstract
Die Verfügbarkeit von qualifizierten Arbeitskräften ist eine zentrale Voraussetzung für den Erfolg eines Unternehmens. Eine städtische Lohnprämie zieht Beschäftigte an und verstärkt den Urbanisierungstrend. In unserer Studie untersuchen wir, ob nicht nur die Lohnprämie, sondern auch der Unternehmensstandort selbst die Attraktivität eines Arbeitsplatzes beeinflusst. Mittels eines experimentellen Untersuchungsdesigns zeigen wir, dass hochqualifizierte Arbeitnehmer unabhängig vom gezahlten Lohn eine Präferenz für städtische Standorte haben, selbst wenn ländliche Standorte attraktive regionale Eigenschaften aufweisen. Der beobachtete Effekt ist allerdings getrieben von Personen, die in städtischen Gebieten aufgewachsen sind. Personen, die in ländlichen Gebieten aufgewachsen sind, zeigen dagegen keine regionalen Präferenzen, weder für noch gegen städtische Gebiete.

Where STEM Graduates Stem From: The Intergenerational Transmission of Comparative Skill Advantages

Abstract
The standard economic model of occupational choice following a basic Roy model emphasizes individual selection and comparative advantage, but the sources of comparative advantage are not well understood. We employ a unique combination of Dutch survey and registry data that links math and language skills across generations and permits analysis of the intergenerational transmission of comparative skill advantages. Exploiting within-family between-subject variation in skills, we show that comparative advantages in math of parents are significantly linked to those of their children. A causal interpretation follows from a novel IV estimation that isolates variation in parent skill advantages due to their teacher and classroom peer quality. Finally, we show the strong influence of family skill transmission on children’s choices of STEM fields.

Ostdeutsche Wirtschaft bisher gut durch Energiekrise gekommen – Implikationen der Gemeinschaftsdiagnose Frühjahr 2023 und amtlicher Länderdaten für die ostdeutsche Wirtschaft
Im Jahr 2022 hat die ostdeutsche Wirtschaft mit 3,0% deutlich stärker expandiert als die Wirtschaft in Westdeutschland (1,5%). Hintergrund ist eine robustere Entwicklung der Arbeitnehmer- und Rentnereinkommen. Auch für das Jahr 2023 prognostiziert das Leibniz-Institut für Wirtschaftsforschung Halle (IWH) deshalb mit 1% eine höhere Zuwachsrate des Bruttoinlandsprodukts in Ostdeutschland als in Deutschland insgesamt (0,3%). Die Arbeitslosenquote dürfte mit 6,8% im Jahr 2023 und 6,7% im Jahr darauf in etwa stagnieren.
