Due to recent conflicts and humanitarian issues, millions of people have sought asylum in countries in Europe. The influx of asylum seekers has sparked debates about the impacts of such migratory flows on resident populations. We study how the recent migration of these forcibly displaced people into Europe affects the mental health of the receiving country residents in Switzerland and Germany. We exploit ...

Hochschulen in Deutschland bieten zunehmend Orientierungsstudienprogramme an, um Studieninteressierte bei ihrer Studienwahl zu unterstützen. Wen Hochschulen mit solchen Programmen erreichen, ist bislang jedoch weitgehend unklar. Unser Beitrag vergleicht die Ausgangslagen Studierender eines Orientierungsstudiums (N = 512) an einer deutschen Universität mit denen regulärer Bachelorstudierender zu Studienbeginn ...

Residential electricity consumers equipped with photovoltaic (PV) systems and battery storage, also referred to as solar prosumers, are transforming electricity markets. While previous research has dealt with various aspects of solar prosumage, dedicated analyses of their interactions with the transmission grid under varying tariff designs are sparse. We explore the influence of different pricing regimes ...

Many governments consider new nuclear power plants to promote decarbonization. On the one hand, dispatchable nuclear plants can complement fluctuating generation from wind and PV. On the other hand, escalating construction costs and times raise economic concerns. This paper investigates the economic threshold at which nuclear plants are an efficient decarbonization option. Building on an extensive ...

Forced migration has intensified in the 21st century, driven by conflicts, persecution, and political instability in regions such as the Middle East, Afghanistan, the Horn of Africa, South-East Asia, Latin America and, most recently, Ukraine. Germany has become a primary destination for refugees within the European Union and one of the largest among the OECD countries. The IAB-BAMF-SOEP Refugee Survey, ...

This paper outlines two studies on education bias in German probability-based surveys. Study 1 reviews data from 67 surveys across 19 survey programs conducted in Germany from 2000 to 2023. We found a consistent underrepresentation of individuals with a low level of formal education. We also found that the transition to self-administered modes due to rising survey costs may exacerbate this bias in ...

Using linked data from the Millennium Cohort Study and National Pupil Database (N = 8,139), this study examined how the timing of school absences (years 1 to 11 between 2006 and 2017) affects achievement at the end of compulsory schooling in England. Absences during any school year are harmful to student achievement. However, absences in years 1 and 6 (the final year of primary school), and between ...

We propose a novel method to detect and disentangle moderate and severe health shocks in a general population survey based on a data-driven classification of sickness absences and hospitalizations. Both types of shocks are widespread with an annual incidence of about 1.7%, which rises steeply with age. We estimate the effects of both shocks on labor market outcomes and find that severe shocks have ...

In conventional proxy VAR analysis, the shocks of interest are identified by external instruments. This is typically accomplished by considering the covariance of the instruments and the reduced-form residuals. Alternatively, the instruments may be internalized by augmenting the VAR process by the instruments or proxies. These alternative identification methods are compared and it is shown that the ...

Existing research has demonstrated that wealthier individuals differ in family formation. Potential explanations draw on wealth’s use and symbolic value as well as the relative economic bar of family formation. This study examines the relationship between wealth and three family formation events in Germany: first cohabitation, marriage, and birth. Data from the German Socio-Economic Panel Study (2002–2017) ...

We employ a control function methodology, complemented by various identification strategies, to causally estimate the heterogeneous effects of broadband availability on firms’ total factor productivity (TFP) across 46 two-digit manufacturing and service industries in Germany from 2010 to 2015. Throughout this period, the availability of broadband, defined as access to transmission rates of at least ...

Individuals vary considerably in how much they earn during their lifetimes. This study examines the role of the tax‐and‐transfer system in mitigating such inequalities, which could otherwise lead to disparities in living standards. Utilizing a life‐cycle model, we determine that the tax‐and‐transfer system offsets 45% of lifetime earnings inequality attributed to differences in productive abilities ...

We show that in a New Keynesian model with household heterogeneity, fiscal policy can be a perfect substitute for monetary policy: three simple conditions for consumption taxes, labor taxes, and the government debt level are sufficient to induce the same consumption and labor supply of each household and, thus, the same allocation as interest rate policies. When monetary policy is constrained by a ...

Who makes it to the top? We use the leading socio-economic survey in Germany, supplemented by extensive data on the rich, to answer this question. We identify the key predictors for belonging to the top 1 percent of income, wealth, and both distributions jointly. Although we consider many, only a few traits matter: Entrepreneurship and self-employment in conjunction with a sizable inheritance of company ...

Background: Populations experiencing precarity face heightened mental health inequities, especially during crises. In this regard, it is established that socio-economic status (SES) and social isolation are critical factors influencing mental health outcomes, which interact syndemically. Understanding their interrelated mechanisms is crucial for developing effective public health strategies to support ...

BackgroundHealth system resilience, the ability of a health system to maintain its functions under stress, has received increasing attention in recent years. Shortcomings in health system resilience are often most visible in the most vulnerable settings, including the care for asylum seekers and refugees. We therefore examined how the German health system responded to challenges and uncertainties during ...

Earnings are often top-coded (right-censored) in administrative registers. The censoring threshold in the case of Germany is the limit value for social security contributions, leading to a substantial fraction of censoring: For example, about 12%of male workers inWest Germany are affected, rising to above 30% for highly educated prime-aged workers. This missing right tail of the earnings distribution ...

During the 2022 energy crisis, electricity prices across Europe have risen to unprecedented heights. In a case study for Germany, this work investigates to which extent price spikes can be attributed to changes in upstream commodity prices, and to which degree strategic behavior by generators may have contributed to the situation. Electricity markets are more prone to the effects of such behavior if ...

We show that in school systems with grade retention or redshirting birth cohort size is negatively related to the grade-level share of students who are too old for their grade. This compositional effect gives rise to an upward bias in estimates of class size effects based on commonly used research designs exploiting within-school variation in birth cohort size. Using data for all primary schools in ...
