Tropospheric Ozone and Skin Aging: Results from Two German Cohort Studies

During the last two decades, it has been well established that a short-term exposure to ozone (O3) elicits an oxidative stress response in human and mouse skin, which leads to aberrant transcriptional expression of genes consistent with increased skin aging. Whether a long-term exposure to ambient O3 is associated with any skin aging traits, has remained unclear. We addressed this question in two elderly ...

Does Residential Segregation Matter for the Labor Market Performance of Immigrants? Evidence from Germany

With the arrival of over one million asylum seekers in Germany in 2015, policy discussions opened whether refugees should be spread across the country or spatially concentrated in order to facilitate their integration in society. When an immigrant locates in a residential area with many natives or many foreigners he has access to different respective social networks which are important for the labor ...

Housing Rent Dynamics and Rent Regulation in St. Petersburg (1880-1917)

This article studies the evolution of housing rents in St. Petersburg between 1880 and 1917, covering an eventful period of Russian and world history. We collect and digitize over 5,000 rental advertisements from a local newspaper, which we use together with geo-coded addresses and detailed structural characteristics to construct a quality-adjusted rent price index in continuous time. We provide the ...

Language Skills and Employment Rate of Refugees in Germany Improving with Time

Asylum seekers migrating to Germany remains a hotly debated topic. The second wave of a longitudinal survey of refugees shows that their integration has progressed significantly, even though some refugees came to Germany in poor health and with little formal education. Compared to the previous year, refugees’ German skills have improved, as have their participation rates in the workforce, education, ...

What Determines the Elasticity of Substitution between Capital and Labor? A Literature Review

This paper provides the first comprehensive review of the empirical and theoretical literature on the determinants of the elasticity of substitution between capital and labor. Our focus is on the two-input constant elasticity of substitution (CES) production function. By example of the U.S., we highlight the distinctive heterogeneity in empirical estimates of σ at both the aggregate and industrial ...

Net Neutrality and CDN Intermediation

We analyze competition between Internet Service Providers (ISPs) where consumers demand heterogeneous content within two Quality-of-Service (QoS) regimes, Net Neutrality and Paid Prioritization, and show that paid prioritization increases the static efficiency compared to a neutral network. We also consider paid prioritization intermediated by Content Delivery Networks (CDNs). While the use of CDNs ...

How Do Households Allocate Risk?

Individuals often have to decide to which degree of risk they want to expose others, or how much risk to accept if their choice has an externality on third parties. One typical application is a household. We run an experiment in the German Socio-Economic Panel with two members from 494 households. Participants have a good estimate of each other’s risk preferences, even if not explicitly informed. They ...

Do Justice Perceptions Support the Concept of Equal Sacrifice? Evidence from Germany

The ability-to-pay approach assesses taxes paid as a sacrifice by the taxpayers. This raises the question of how to define and how to measure it: in absolute, relative, or marginal terms? U.S. respondents prefer a tax schedule that is either a pure (absolute) Equal Sacrifice or a mixture of Equal Sacrifice and Utilitarianism [Weinzierl, 2014]. To determine whether Germans prefer absolute, relative, ...
