Immigration is a crucial issue in contemporary politics, and attitudes towards immigration are highly dispersed in many countries. We treat individuals' immigration friendliness (IF) as a feature of their self-image or identity and hypothesize that, similar to other pro-social self-images,...

This paper hypothesizes and empirically establishes the persistent effects of novelty-seeking traits on crosscountry differences in scientific knowledge creation. I use data on the prevalence of specific allele variants of the human DRD4 exon III gene, which population geneticists have linked to...

In spite of scientific agreement on the negative effects of anthropogenic climate change, efforts to find cooperative solutions on the international level have been unsatisfactory so far. Trade sanctions in the form of import tariffs are one principal measure discussed as a means to foster...

Shall investments become more robust or more short-lived if unfavorable exogeneous conditions become more uncertain? What if the investments' design is irreversible for its whole life time? Such decision problems are frequently encountered, for example in infrastructure construction. We analyze...

Using subjective well-being data for more than 91,000 individuals in 30 OECD countries, 1990-2008, we study how people's implicit aversion towards inflation varies with income and other socio-economic characteristics. While inflation aversion decreases with income, it increases with the...

We use data on the subjective well-being (SWB) of more than 91,000 individuals in 30 member countries of the Organization for Economic Cooperation and Development (OECD) to assess the well-being effects of unemployment, inflation and national income growth. The relationships found are used to...

Given the bleak prospects for a global agreement on coordinated policies to mitigate climate change, political pressure is increasing among industrialized countries for unilateral abatement. A major challenge thereby is the appropriate response to the threat of emissions leakage. Border carbon...

This paper explores transnational environmental agreements on climate change. As the Paris agreement of 2015 contains no binding emission reduction targets for nation states, understanding other forms of cooperation as complements to the United Nations Framework Convention on Climate Change...

Carbon-based import tariffs are discussed as policy measures to reduce carbon leakage and increase the global cost-effectiveness of unilateral CO2 emission pricing. We assess how the potential of carbon tariffs to increase cost-effectiveness of unilateral climate policy depends on the magnitude...
