The construction industry remains a key pillar of the German economy. According to the latest construction volume calculations by DIW Berlin, the value of construction in 2014 and 2015 is forecast to grow far more rapidly than the economy as a whole: by a price-adjusted 3.3 percent and 2.1 percent in 2014 and 2015, respectively. Currently, new residential construction is an important engine for growth ...
This study examines the causal link between individuals' occupational knowledge, educational choices, and labor market outcomes. We proxy occupational knowledge with mandatory visits to job information centers (JICs) in Germany while still attending school. Exogenous variation in the location and timing of JIC openings allow estimating causal effects in a difference-in-difference setup. Combining linked ...
This paper studies the causal effect of student internship experience on labor market choices and wages later in life. We use variation in the introduction and abolishment of mandatory internships at German universities as an instrument for completing an internship while attending university. Employing longitudinal data from graduate surveys, we find positive and significant wage returns of about six ...
This paper investigates the short-term effects of a reduction in the length of high school on students' personality traits using a school reform carried out at the state level in Germany as a quasi-natural experiment. Starting in 2001, academic-track high school (Gymnasium) was reduced from nine to eight years in most of Germany's federal states, leaving the overall curriculum unchanged. This enabled ...
Based on representative micro data for Germany, we compare the incomes of self-employed with those of wage workers. Our results show that the median self-employed entrepreneur with employees earns significantly more than the median salaried employee, while the median solo entrepreneur earns less. However, solo entrepreneurship pays for those with a university entrance degree but no further professional ...
This paper experimentally investigates the nature of image concerns in gift giving. For this, we test variants of dictator and impunity games where the influences of social preferences on behavior are kept constant across all games. Givers maximize material payoffs by pretending to be fair when receivers do not know the actual surplus size, implying that portraying an outward appearance of norm compliance ...
To counteract the financial pressure emerging in aging societies, statutory pay‐as‐you‐go pension schemes are undergoing fundamental reforms in many Western countries. Starting with cohort 1937, Germany introduced permanent pension deductions for early retirement. This paper examines the evolution of the profitability of pension contributions against the background of this reform for cohorts 1935‐1945. ...
This paper studies the bank-sovereign link in a dynamic stochastic general equilibrium set-up with strategic default on public debt. Heterogeneous banks give rise to an interbank market where government bonds are used as collateral. A default penalty arises from a breakdown of interbank intermediation that induces a credit crunch. Government borrowing under limited commitment is costly ex ante as bank ...
This paper explores the long run relationship between public and private investment in the euro area in terms of capital stocks and gross investment flows. Panel techniques accounting for international spillovers are employed. While private and public capital stocks are cointegrated, the evidence is quite fragile for public and private investment flows. They enter a long run relationship only after ...
