Alternative Recipes for Life Satisfaction: Evidence from Five World Regions

In most cross-national research on Life Satisfaction (LS) an implicit assumption appears to be that the correlates of LS are the same the world over; ‘one size fits all’. Using data from the World Values Survey (1999–2014), we question this assumption by assessing the effects of differing personal values/life priorities on LS in five world regions: the West, Latin America, the Asian-Confucian region, ...

DIW Konjunkturbarometer März: Industrie stark, Lockdown belastet Dienstleister

Das Konjunkturbarometer des Deutschen Instituts für Wirtschaftsforschung (DIW Berlin) ist im März um etwa sieben Punkte auf nun 104 Punkte gefallen. Im ersten Quartal dieses Jahres dürfte die deutsche Wirtschaft nach bisherigen Erkenntnissen um rund anderthalb Prozent geschrumpft sein. Zwar setzt die Industrie ihren Aufwärtstrend vom Lockdown weitestgehend unbeeindruckt fort – ...

The Value of Data for Prediction Policy Problems: Evidence from Antibiotic Prescribing

Large-scale data show promise to provide efficiency gains through individualized risk predictions in many business and policy settings. Yet, assessments of the degree of data-enabled efficiency improvements remain scarce. We quantify the value of the availability of a variety of data combinations for tackling the policy problem of curbing antibiotic resistance, where the reduction of inefficient antibiotic ...

Der gesellschaftliche Mehrwert verknüpfter Daten: Algorithmen als Entscheidungshilfen bei Antibiotikaverschreibungen

Personendaten aus der Verwaltung (Administrativdaten) haben sich in den letzten Jahrzehnten als wichtige Basis zur Evaluierung von Politikmaßnahmen erwiesen. Durch maschinelles Lernen können basierend auf diesen Daten auch Vorhersagen getroffen werden, die zur Lösung gesellschaftlicher Problemstellungen beitragen. Hierzu gehören beispielsweise das Aufspüren von Steuerbetrug und eine bessere medizinische ...

25 Years of European Merger Control

We study the determinants of common European merger policy over its first 25 years, from 1990 to 2014. Using a novel dataset at the level of the relevant antitrust markets and containing all relevant merger cases notified to the European Commission, we evaluate how consistently arguments related to structural market parameters – dominance, rising concentration, barriers to entry, and foreclosure – ...

Testing Identification via Heteroskedasticity in Structural Vector Autoregressive Models

Tests for identification through heteroskedasticity in structural vector autoregressive analysis are developed for models with two volatility states where the time point of volatility change is known. The tests are Wald-type tests for which only the unrestricted model, including the covariance matrices of the two volatility states, has to be estimated. The residuals of the model are assumed to be from ...

On the Difficulties to Calculate Infrastructure Charges for Heavy Goods Vehicles: A Review of 15 Years’ Experience in Germany

This paper analyses the calculation principles used for determining the level and differentiation ofHGV charges in Germany. It demonstrates that calculating average cost-based charges is far fromstraightforward, even with an agreed methodology, and involves sensitive methodological choices.Based on a review of available studies, the paper argues that estimating marginal costs does notnecessarily involve ...

Heterogeneous Mortality - Empirical Analyzes based on the SOEP

The aim of the project is the empirical investigation of the differential life expectancy of different socio-economic groups. In particular, it will be analyzed whether there are systematic differences in life expectancy according to occupation, industry or position in the occupation. The study will also work out the heterogeneous effects within the groups according to different individual...
