Do Digital Information Technologies Help Unemployed Job Seekers Find a Job? Evidence from the Broadband Internet Expansion in Germany
Nicole Gürtzgen, André Diegmann, Laura Pohlan, Gerard J. van den Berg
European Economic Review,
February
2021
Abstract
This paper studies effects of the introduction of a new digital mass medium on reemployment of unemployed job seekers. We combine data on broadband internet availability at the local level with German individual register data. We address endogeneity by exploiting technological peculiarities that affected the roll-out of broadband internet. Results show that broadband internet improves reemployment rates after the first months in unemployment for males. Complementary analyses with survey data suggest that internet access mainly changes male job seekers’ search behavior by increasing online search and the number of job applications.

The Internet Effects on Sex Crime Offenses – Evidence from the German Broadband Internet Expansion
André Diegmann
Journal of Economic Behavior and Organization,
September
2019
Abstract
This paper studies the effects of the introduction of a new mass medium on sex crime in Germany. I use unique data on criminal offenses and broadband internet measured at the municipal level to shed light on this issue. In order to address endogeneity in broadband internet availability, I exploit technical peculiarities at the regional level that determine the roll-out of high-speed internet. Results provide evidence of a substitution effect of internet exposure on sex crime. The substitution effect is neither driven by differences in reporting behavior, nor by matching processes at the victim and offender side. This suggests that the consumption of extreme media plays an important role in explaining the documented high-speed internet effect.

Abstract
This paper studies effects of the introduction of a new digital mass medium on reemployment of unemployed job seekers. We combine data on high-speed (broadband) internet availability at the local level with German individual register data. We address endogeneity by exploiting technological peculiarities that affected the roll-out of high-speed internet. The results show that high-speed internet improves reemployment rates after the first months in unemployment. This is confirmed by complementary analyses with individual survey data suggesting that internet access increases online job search and the number of job interviews after a few months in unemployment.

Paternal Unemployment During Childhood: Causal Effects on Youth Worklessness and Educational Attainment
Steffen Müller, Regina T. Riphahn, Caroline Schwientek
Oxford Economic Papers,
Nr. 1,
2017
Abstract
Using long-running data from the German Socio-Economic Panel (1984–2012), we investigate the impact of paternal unemployment on child labour market and education outcomes. We first describe correlation patterns and then use sibling fixed effects and the Gottschalk (1996) method to identify the causal effects of paternal unemployment. We find different patterns for sons and daughters. Paternal unemployment does not seem to causally affect the outcomes of sons. In contrast, it increases both daughters’ worklessness and educational attainment. We test the robustness of the results and explore potential explanations.

Effects of Incorrect Specification on the Finite Sample Properties of Full and Limited Information Estimators in DSGE Models
Sebastian Giesen, Rolf Scheufele
Journal of Macroeconomics,
June
2016
Abstract
In this paper we analyze the small sample properties of full information and limited information estimators in a potentially misspecified DSGE model. Therefore, we conduct a simulation study based on a standard New Keynesian model including price and wage rigidities. We then study the effects of omitted variable problems on the structural parameter estimates of the model. We find that FIML performs superior when the model is correctly specified. In cases where some of the model characteristics are omitted, the performance of FIML is highly unreliable, whereas GMM estimates remain approximately unbiased and significance tests are mostly reliable.

Vererbung von Arbeitslosigkeit: Wie der Vater, so der Sohn?
Steffen Müller
Wirtschaft im Wandel,
Nr. 2,
2016
Abstract
Jugendarbeitslosigkeit und mangelnde Chancen sozialen Aufstiegs gehören zu den wichtigsten sozialpolitischen Herausforderungen in vielen Ländern. Die Probleme erweisen sich als so hartnäckig, dass die These naheliegt, sie würden innerhalb der Familien „vererbt“. Eine Studie des IWH und der Friedrich-Alexander-Universität Erlangen-Nürnberg hat jetzt erstmals für Deutschland untersucht, wie lange junge Männer, die als Kinder einen zeitweise arbeitslosen Vater hatten, später selbst arbeitslos gewesen sind. Zudem wurde geprüft, ob die Ursache für die Arbeitslosigkeit der Söhne in der Arbeitslosigkeit der Väter selbst oder in gemeinsamen familiären Faktoren zu suchen ist, die zu einer höheren Arbeitslosigkeit von Vätern und Söhnen führen.
