Housing property is the most important position in a household's wealth portfolio. Even though there is strong evidence that house price cycles and saving patterns behave synchronously, the underlying causes remain controversial. The present paper examines if there is a wealth effect of house...

Der Frauenanteil in den Vorständen und Aufsichtsräten der 100 größten Banken in Deutschland ist im vergangenen Jahr jeweils leicht auf knapp neun beziehungsweise 23 Prozent gestiegen. Bei den 60 größten Versicherungen ist die Dynamik hingegen zum Erliegen gekommen: In beiden Gremien ging...

Die Geschlechterquote für Aufsichtsräte in Deutschland greift: In den Kontrollgremien der gut 100 Unternehmen, die an die Quote gebunden sind, ist der Frauenanteil bis Ende 2017 auf durchschnittlich gut 30 Prozent gestiegen - das waren knapp drei Prozentpunkte mehr als im Jahr zuvor. Fast zwei...

This paper investigates the influence of industrial relations on firm wage premia in Germany. OLS regressions for the firm effects from a two-way fixed effects decomposition of workers' wages by Card, Heining, and Kline (2013) document that average premia are larger in firms bound by collective...

In diesem Bericht wird ein umfangreicher Datensatz von über sechs Millionen Haushaltsstromtarifen für alle Postleitzahlgebiete Deutschlands analysiert. Die Entwicklung der Einzelhandelsstrompreise zwischen Januar 2007 und August 2014 unterscheidet sich je nach Anbieter und Tarif stark....

Given theoretical premises, gender wage gap adjusted for individual characteristics is likely to vary over age. We extend DiNardo, Fortin and Lemieux (1996) semi-parametric technique to disentangle year, cohort and age effects in adjusted gender wage gaps. We rely on a long panel of data from...

Wegen fehlender amtlicher Statistiken schätzt das IfM Bonn seit Mitte der 1990er Jahre die Anzahl der Unternehmen in Deutschland, die vor der Übergabe stehen. Die vorliegende Schätzung für den Zeitraum 2018 bis 2022 kommt zum Ergebnis, dass etwa 150.000 Unter-nehmen mit rund 2,4 Mio....

Die Mietpreisbremse ist das zentrale wohnungsmarktpolitische Projekt der vergangenen Jahre. Umso größer war die Ernüchterung, als erste empirische Studien - auch des DIW Berlin - darauf hindeuteten, dass die Mietpreisbremse den Anstieg der Mieten insgesamt nicht spürbar verlangsamt. Dieses...

Over the past year, the proportion of women serving on the executive and supervisory boards of the top 100 largest banks in Germany rose slightly to almost nine and 23 percent, respectively. However, growth has come to a halt in the 60 largest insurance companies: on both executive and...

The gender quota for supervisory boards in Germany is effective: by the end of 2017, the proportion of women on the supervisory boards of a good 100 companies that are subject to the quota had risen to 30 percent-three percentage points more than in the previous year. Almost two-thirds of the...

This paper investigates the influence of industrial relations on firm wage premia in Germany. OLS regressions for the firm effects from a two-way fixed effects decomposition of workers’ wages by Card, Heining, and Kline (2013) document that average premia are larger in firms bound by...

We estimate the spatially differential effects of a nationally uniform minimum wage that was introduced in Germany in 2015. To this end, we use a micro data set covering the universe of employed and unemployed individuals in Germany from 2011 to 2016 and a difference‐in‐differences based...

We evaluate the impact of a major European state aid programme for broadband deployment applied to rural areas in the German state of Bavaria in the years 2010 and 2011. Using matched difference-in-differences estimation strategies, we find that aided municipalities have – depending on...

Ausländer haben das Existenzgründungsgeschehen in den Jahren 2007 bis 2016 sowohl in Deutschland als auch Nordrhein-Westfalen in erheblichem Maße mitgeprägt. Eine besonders große Rolle haben ausländische Gründer im gewerblichen Bereich gespielt. Differenzierende Analysen auf Basis der...

Der Bericht analysiert die Inanspruchnahme von Freiflächen, insbesondere Landwirtschaftsfläche, durch Photovoltaik-Anlagen, die im Rahmen des Gesetzes für den Ausbau erneuerbarer Energien (EEG 2017) eine Förderberechtigung erhielten. Die Analyse beruht auf Einzeldaten der in neun...

Das Marktforschungsunternehmen GfK SE erfasste von Juli 2016 bis Juni 2017 erstmals im Rahmen einer repräsentativen Tagebuchstudie systematisch die Lebensmittelabfälle in deutschen Privathaushalten. Fast 7.000 Haushalte wurden über einen Zeitraum von je 14 Tagen über ihren Umgang mit...

We investigate the role of individual labor income as moderator of the parental subjective well-being trajectories around the first childbirth. By analyzing the German Socioeconomic Panel Survey data, we find that high-income parents enjoy their first child less than low-income ones. In a low...

This paper investigates the effect of the refugee crisis, and the related government's asylum policy, on concerns about immigration of the German population. Exploiting exogenous variation in survey interview timing of the German Socio-Economic Panel (SOEP), I employ a difference-in-differences...

German public sector wage restraint has been explained through the presence of a specific type of inter-sectoral wage coordination in the industrial relations system - i.e., export sector-led pattern bargaining. This paper has a twofold ambition. First, as a literature-assessing exercise, I...

This paper uses information on all export transactions of goods by German firms with countries outside the European Union from 2009 to 2014 to document for the first time the patterns of export participation at the firm-good-destination level over time and to investigate the link between the...

Over the 2000s, many federal states in Germany shortened the duration of secondary school by one year while keeping the curriculum unchanged. Exploiting quasi-experimental variation due to the staggered introduction of this reform allows me to identify the causal effect of increased learning...

We propose the so-called domestic "embodied unit labor costs" (EULC) at the country-sector level as a new cost-related basis for measures of international competitiveness. EULC take into account that a sector's labor costs constitute only a small share of its total cost which to a large extent...

Vertragsnaturschutz bzw. Naturschutz gegen Entgelt wird im Wald bisher nur vereinzelt umgesetzt. Vor diesem Hintergrund analysiert das Verbundforschungsprojekt 'Vertragsnaturschutz im Wald (WaVerNa)' den gegenwärtigen Umsetzungsstand sowie die Potenziale und Hemmnisse von Vertragsnaturschutz im...

This study estimates the causal effect of working hours on health. We deal with the endogeneity of working hours through instrumental variables techniques. In particular, we exploit exogenous variation in working hours from statutory workweek regulations in the German public sector as an...

This paper studies the research interests, paradigmatic orientation and political orientation of about 700 full professors of economics at universities located in German-speaking countries. In doing so, we captured biographical and institutional information on these professorships by collecting...

We use data from six cohorts of university graduates in Germany to assess the extent of gender gaps in college and labor market performance twelve to eighteen months after graduation. Men and women enter college in roughly equal numbers, but more women than men complete their degrees. Women...

This paper investigates whether the stepping-stone effect of temporary agency employment varies over the business cycle. Using German administrative data for the period 1985-2012 and an estimation framework based on the timing-of-events model, we estimate in-treatment and post-treatment effects...

This study examines the potential impact of works councils and unions on the deployment of fixed-term contracts and agency temps. We report inter al. that works councils are associated with a higher number of temporary agency workers when demand volatility is high while the opposite holds for...

Die Digitalisierung der Industrie, die im Konzept der Industrie 4.0 ihren Niederschlag findet, weist auf eine Entwicklung hin, die mit dem Konzept der „Informatisierung“ eingeführt und weiterentwickelt wurde. Die Einführung informationstechnologischer Innovationen wurde in benachbarten...
