Mitigating Environmental and Public-Safety Risks of United States Crude-by-Rail Transport

We present a medium-term market equilibrium model of the North American crude oil sector via which we develop a scenario analysis to investigate strategies to mitigate the environmental and public-safety risks from crude-by-rail transportation across the United States. The model captures crude oil movements across rail- roads, pipelines and waterways, while distinguishing between light and heavy crude ...

Assessing the Impact of Payment Card Fee Regulation

Genome-Wide Association Study Identifies 74 Loci Associated with Educational Attainment

Educational attainment is strongly influenced by social and other environmental factors, but genetic factors are estimated to account for at least 20% of the variation across individuals1. Here we report the results of a genome-wide association study (GWAS) for educational attainment that extends our earlier discovery sample1, 2 of 101,069 individuals to 293,723 individuals, and a replication study ...

Coordination of Renewable Energy Remuneration Schemes through Information Exchange

The increasing scale and dynamics of the global market for renewable energy technologies has often resulted in unexpected high deployment volumes in EU Member States. These deployment peaks were particularly strong for solar photovoltaic (PV) technologies in countries using feed-in tariff remuneration mechanisms. In this paper, we develop an analytic model to capture the interactions of national remuneration ...

Typical Employment Subject to Mandatory Social Security Contributions Remains the Norm

This increase in employment figures primarily benefited those in marginal employment or solo entrepreneurs and had less of an impact on those in typical employment. In fact, the present analysis ...

Employment Subject to Mandatory Social Security Contributions Is Anything but Outdated: Eight Questions to Gert G. Wagner

The Link between R&D, Innovation and Productivity: Are Micro Firms Different?

"Employment subject to mandatory social security contributions is anything but outdated": Eight Questions to Gert G. Wagner

Professor Wagner, in the 1980s, sociologist Ulrich Beck posited in his book Risikogesellschaft (published in English as “Risk Society” in 1992) that working conditions would become increasingly complex. Employment subject to mandatory social security contributions would decline and precarious employment would increase. Has this happened? No, it hasn’t. Although precarious jobs have ...
