Die LOHAS im Kontext der Sinus-Milieus

Aktuelle Diskussionen im Kontext des nachhaltigen Konsums sind ohne den LOHAS (Lifestyle of Health and Sustainability) als neuartige Zielgruppe kaum noch denkbar. Auch wenn der LOHAS die zentralen Anforderungen an das Lebensstilkonzept erfüllt, so lassen sich die abgeleiteten Implikationen nur schwierig in ein operativ erfolgreiches Nachhaltigkeitsmarketing übertragen. Die Verortung des LOHAS innerhalb der Sinus-Milieus kann die Unsch?rfe dieses Ansatzes reduzieren und so zus?tzlich Informationen für das Marketing bereitstellen.     

Combination of evidence from multiple administrative data sources: quality assessment of the Austrian register‐based Census 2011

This article investigates the quality of register data in the context of a standardized quality framework. The special focus of this work lies on the assessment of census data and how to deal with uncertainty that arises from multiple sources (registers). To take the uncertainty associated with support and conflict between several registers into account, Dempster–Shafer's theory of evidence is applied. This ‘fuzzy’ approach allows us to investigate the quality of databases with multiple underlying sources for a single attribute and to provide both quality measures and plausibility intervals.     

Dynamic Harmonic Regression Methods in the Analysis of Stochastic Time Series Exhibiting Strong Trigonometric Components

Bounded Rationality in Principal‐Agent Relationships

We conducted six treatments of a standard moral hazard experiment with hidden action. The behavior in all treatments and periods was inconsistent with established agency theory. In the early periods, behavior differed significantly between treatments. This difference largely vanished in the final periods. We used logit agent quantal response equilibrium (LAQRE) as a device to grasp boundedly rational behavior and found the following: (1) LAQRE predictions are much closer to subjects' behavior in the laboratory; (2) LAQRE probabilities and experimental behavior show remarkably similar patterns; and (3) including social preferences in LAQRE does not better explain the experimental data; (4) LAQRE cannot explain the contract offers of some players who seem to choose some focal contract parameters.     

Peak-load pricing with different types of dispatchability

Structural changes in EC trade intensities

The European Economic Community has now been in existence for about 20 years. Five years have elapsed since it was enlarged. What progress have the member countries made in the integration of their foreign trade? What would be the repercussions of a southward extension of the EC to take in Greece, Portugal and Spain?

Comparing inequality aversion across countries when labor supply responses differ

We analyze to which extent social inequality aversion differs across nations when controlling for actual country differences in labor supply responses. Towards this aim, we estimate labor supply elasticities at both extensive and intensive margins for 17 EU countries and the US. Using the same data, inequality aversion is measured as the degree of redistribution implicit in current tax-benefit systems, when these systems are deemed optimal. We find relatively small differences in labor supply elasticities across countries. However, this changes the cross-country ranking in inequality aversion compared to scenarios following the standard approach of using uniform elasticities. Differences in redistributive views are significant between three groups of nations. Labor supply responses are systematically larger at the extensive margin and often larger for the lowest earnings groups, exacerbating the implicit Rawlsian views for countries with traditional social assistance programs. Given the possibility that labor supply responsiveness was underestimated at the time these programs were implemented, we show that such wrong perceptions would lead to less pronounced and much more similar levels of inequality aversion.     

Number,Age Composition and School Achievements of Siblings in Two African Capital Cities

This paper uses biographical data from Dakar and Yaoundé, two large African cities, to study the link between number of siblings and school attainment. The data describe all fertility events experienced by parents and the number of siblings of each child over time. The average family size effect is estimated first. The family size effect at different ages is then estimated. The results show that, in Dakar, both the overall and age-specific effect of family size on education are negative and statistically significant. In Yaoundé, the overall effect is not significant, but negative effects at some schooling ages (between 14 and 17) are observed in this study. Finally, the negative impact of family size on school achievement seems to be driven more by elder siblings than by younger ones.     

Funding liquidity risk: Definition and measurement

Funding liquidity risk has played a key role in all historical banking crises. Nevertheless, a measure for funding liquidity risk based on publicly available data remains so far elusive. We address this gap by showing that aggressive bidding at central bank auctions reveals funding liquidity risk. We can extract an insurance premium from banks’ bids which we propose as a measure of funding liquidity risk. Using a unique data set consisting of all bids in all auctions for the main refinancing operation conducted at the ECB between June 2005 and October 2008 we find that funding liquidity risk is typically stable and low, with occasional spikes especially around key events during the recent crisis. We also document downward spirals between funding liquidity risk and market liquidity. As measurement without clear definitions is impossible, we initially provide definitions of funding liquidity and funding liquidity risk.
