Is there a "Race-to-the-Bottom" in the Setting of Welfare Benefit Levels? Evidence from a Policy Intervention

In this paper we investigate whether local governments react on the welfare benefit levels in neighboring jurisdictions when setting their own benefit levels. We solve the simultaneity problem arising from the welfare game by utilizing a policy intervention; more specifically, we use a centrally geared exogenous placement of a highly welfare prone group (refugees) among Swedish municipalities as an instrument. The IV estimates indicate that there exists a "race-to-the-bottom" and that the effect is economically as well as statistically significant; if the neighboring municipalities decrease their welfare benefit level with 100 SEK, a municipality decreases its benefit level with approximately 59 SEK. This result is robust to several alternative model specifications.Welfare benefit level; Strategic interactions; Race-to-the-bottom; Policy intervention

Ethnic Diversity and Preferences for Redistribution

In recent decades, the immigration of workers and refugees to Europe has increased substantially, and the composition of the population in many countries has consequently become much more heterogeneous in terms of ethnic background. If people exhibit in-group bias in the sense of being more altruistic to one's own kind, such increased heterogeneity will lead to reduced support for redistribution among natives. This paper exploits a nationwide program placing refugees in municipalities throughout Sweden during the period 1985{94 to isolate exogenous variation in immigrant shares. We match data on refugee placement to panel survey data on inhabitants of the receiving municipalities to estimate the causal effects of increased immigrant shares on preferences for redistribution. The results show that a larger immigrant population leads to less support for redistribution in the form of preferred social benefit levels. This reduction in support is especially pronounced for respondents with high income and wealth. We also establish that OLS estimators that do not properly deal with endogeneity problems - as in earlier studies - are likely to yield positively biased (i.e., less negative) effects of ethnic heterogeneity on preferences for redistribution.income redistribution, ethnic heterogeneity, immigration

Analysis of polycyclic aromatic hydrocarbons (PAHs) and their derivatives in biochar treated stormwater

Polycyclic aromatic hydrocarbons (PAHs), oxygenated PAHs (oxy-PAHs) and nitrogen heterocyclic polycyclic aromatic compounds (N-PACs) are persistent and semi-volatile organic compounds primarily formed due to incomplete combustion of organic material or, in the case of the derivatives, through transformation reactions of PAHs. Their presence in the environment is ubiquitous and many of them have been proven carcinogenic, teratogenic, and mutagenic. These toxic pollutants can therefore pose a threat to both ecosystem and human health and urges for remediation strategies for PAHs and derivatives from water bodies. Biochar is a carbon-rich material resulting from the pyrolysis of biomass resulting in a very porous matter with high surface area for an enhanced interaction with chemicals. This makes biochar a promising alternative for filtering micropollutants from contaminated aquatic bodies. In this work, a previously developed and validated methodology for the analysis of PAHs, oxy-PAHs and N-PACs in surface water samples was adapted for its utilization in biochar treated stormwater with special emphasis on scaling down the solid-phase extraction as well as including an additional filtering step for the removal of particulate matter in the media. & BULL; Optimized extraction method for PAHs, oxy-PAHs and N-PACs from stormwater treated with biochar. & BULL; Biochar strongly impacts the stormwater matrix and, therefore, additional steps are required in the extraction methodology. & BULL; Solid-phase extraction combined with GC-MS have been used to analyse PAHs, oxy-PAHs and N-PACs in stormwater treated with biochar
