Paying for Safety: Preferences for Mortality Risk Reductions on Alpine Roads

This paper presents a choice experiment, which values reductions in mortality risk on Alpine roads. These roads are on one hand threatened by common road hazards, on the other hand they are also endangered by natural hazards such as avalanches and rockfalls. Drawing on choice data from frequently exposed and barely exposed respondents, we are not only able to estimate the VSL but to explore how the respondents differ in their individual willingness-to-pay depending on personal characteristics. To address heterogeneity in preferences for risk reduction, we use a non-linear conditional logit model with interaction effects. The best estimate of the VSL in the context of fatal accidents on Alpine roads is in the range of €4.9–5.4 million with distinct differences between the urban and the mountain sample groups. We find the VSL to be significantly altered by socio-economic factors but only marginally altered by the type of hazard.Value of Statistical Life, Choice Experiment, Natural Hazard Mitigation, Traffic Safety

Policy Evaluation and Economic Policy Advice

Arguably, one of the most important developments in the field of applied economics during the last decades has been the emergence of systematic policy evaluation, with its distinct focus on the establishment of causality.By contrast to the natural sciences, the objects of our scientific interest typically exert some influence on their treatment status under the policy to be evaluated and on their economic outcomes. Thus, economic policy advice can only be successful, if it is based on an appropriate study design, experimental or observational. It will strive in societies that provide liberal access to data, accept the merits of randomized assignment and guard the independence of research institutions.Policy evaluation, applied economics, causality, policy advice

Electroweak symmetry breaking and collider signatures in the next-to-minimal composite Higgs model

We conduct a detailed numerical analysis of the composite pseudo-Nambu-Goldstone Higgs model based on the next-to-minimal coset $\text{SO}(6)/\text{SO}(5)\cong\text{SU}(4)/\text{Sp}(4)$, featuring an additional SM singlet scalar in the spectrum, which we allow to mix with the Higgs boson. We identify regions in parameter space compatible with all current experimental constraints, including radiative electroweak symmetry breaking, flavour physics, and direct searches at colliders. We find the additional scalar, with a mass predicted to be below a TeV, to be virtually unconstrained by current LHC data, but potentially in reach of run 2 searches. Promising indirect searches include rare semi-leptonic $B$ decays, CP violation in $B_s$ mixing, and the electric dipole moment of the neutron.Comment: 32 pages + appendices, 9 figures. v2: minor clarifications, matches the JHEP versio

Polar codes in network quantum information theory

Polar coding is a method for communication over noisy classical channels which is provably capacity-achieving and has an efficient encoding and decoding. Recently, this method has been generalized to the realm of quantum information processing, for tasks such as classical communication, private classical communication, and quantum communication. In the present work, we apply the polar coding method to network quantum information theory, by making use of recent advances for related classical tasks. In particular, we consider problems such as the compound multiple access channel and the quantum interference channel. The main result of our work is that it is possible to achieve the best known inner bounds on the achievable rate regions for these tasks, without requiring a so-called quantum simultaneous decoder. Thus, our work paves the way for developing network quantum information theory further without requiring a quantum simultaneous decoder.Comment: 18 pages, 2 figures, v2: 10 pages, double column, version accepted for publicatio

Mobility within Europe – The Attitudes of European Youngsters

Intensified European integration, enlargement of the EU, and increasing migration activity worldwide have pushed migration and migration policy to the forefront of the European agenda. While many observers hesitate to embrace immigration emanating from outside Europe, sectoral skill shortages and social security systems under demographic pressure have fostered an almost unanimous call for larger mobility within Europe. Yet, neither does intra-European migration respond to this request, nor are the possible consequences of increased migration activity well understood. This paper embeds this discussion into a systematic classification of economic migration research according to its major conceptual and applied questions. The state of theoretical and empirical research in this literature is reviewed briefly, with a focus on intra-European migration. We conclude that the relatively positive assessment of this type of migration mainly derives from its high skill content. To prepare the prediction of future developments, we offer empirical evidence on the determinants of intra-EU-migration by an analysis of the Eurobarometer survey. Unless information deficits, traces of xenophobic tendencies, and the perception of prohibitively high levels of bureaucratic red tape are overcome, intra-European migration will not play the role it is hoped for.Labor mobility, migration intention, intra-EU-migration

Gerontocracy in Motion? – European Cross-Country Evidence on the Labor Market Consequences of Population Ageing

Taking a European cross-country perspective, this paper addresses the most important issues in the nexus of population ageing and labor markets.We start from a descriptive overview of the demographic change currently shaping European societies.The subsequent section intensively discusses the potential consequences of these demographic processes for and interdependencies with the labor market situation in Europe.We place particular emphasis on the issue of non-competitive wage setting. In our empirical application we demonstrate that moderately large birth cohorts seem to experience lower employment rates, but also that education investments might be able to mitigate these consequences, and that the relative economic success of large cohorts might even be disproportionately positive. Finally, in the concluding section we review possible policy options for coping with the consequences of population ageing.Demographic change, cohort size, unemployment

Smoking in Germany: Stylized Facts, Behavioral Models, and Health Policy

It is well known that smoking causes severe adverse health effects, and it seems evident that governments are justified or even obliged to implement measures of tobacco control to mitigate these effects.Yet, as this paper argues with a distinct focus on Germany, the three most important and still largely open questions in the design and implementation of economic and health policy are, whether government action is justified at all, what behavioral patterns this policy should try to alter, and whether the policy measures chosen indeed exert any substantial effects on the targeted outcomes.We conclude that the case for control measures aiming at the prevention of smoking initiation among adolescents is indeed strong, but also that their proper design would benefit from a better understanding of behavioral issues and that their empirical evaluation requires (non-experimental) study designs that facilitate the identification of causal effects.Tobacco, tobacco control, rational addiction
