    Low Emission Zones Improve Air Quality and Health but Temporarily Decrease Life Satisfaction

    Air pollution results in high economic costs arising from its negative impacts on human health, especially in urban areas. Driving restriction policies such as low emission zones (LEZs) are designed to improve air quality. Indeed, empirical analyses in this Weekly Report confirm that LEZs reduce traffic-related air pollution. However, the analyses also reveal unintended adverse effects on secondary ...

    Facebook Shadow Profiles

    Data is often at the core of digital products and services, especially when related to online advertising. This has made data protection and privacy a major policy concern. When surfing the web, consumers leave digital traces that can be used to build user profiles and infer preferences. We quantify the extent to which Facebook can track web behavior outside of their own platform. The network of engagement ...

    Sustainable Financial Literacy and Preferences for Sustainable Investments among Young Adults

    In diesem Beitrag verwenden wir ein Auswahlexperiment bzgl. der Auswahl von Aktienfonds, um die Präferenzen junger Erwachsener für nachhaltige Anlagen im Vergleich zu konventionellen Investmentfonds zu schätzen. Unsere Ergebnisse deuten darauf hin, dass der traditionelle Trade-Off zwischen dem Risiko und der Rendite von Aktienfonds auch bei der Auswahl nachhaltiger Investmentfonds Bestand hat. Der ...

    Comparison of Local Projection Estimators for Proxy Vector Autoregressions

    Different local projection (LP) estimators for structural impulse responses of proxy vector autoregressions are reviewed and compared algebraically and with respect to their small sample suitability for inference. Conditions for numerical equivalence and similarities of some estimators are provided. A new LP type estimator is also proposed which is very easy to compute. Two generalized least squares ...

    Using Mathematical Graphs for Questionnaire Testing in Large-Scale Surveys

    In this article, we present an automated test procedure for examining the filter structure and instructions implemented in electronic questionnaires, and for checking the fit of a questionnaire to the targeted sample. With our approach, we can represent and describe questionnaires using mathematical graphs and specify questionnaire properties in a formal and standardised way. It also allows us deriving ...

    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 ...

    Qualitative versus Quantitative External Information for Proxy Vector Autoregressive Analysis

    A major challenge for proxy vector autoregressive analysis is the construction of a suitable external instrument variable or proxy for identifying a shock of interest. Some authors construct sophisticated proxies that account for the dating and size of the shock while other authors consider simpler versions that use only the dating and signs of particular shocks. It is shown that such qualitative (sign-)proxies ...

    The German Socio-Economic Panel Study is a representative panel study for the German population, collecting data on a broad variety of topics of everyday life, including general wellbeing, household composition, educational aspirations and educational status, income and occupational biographies, leisure time activities, housing, health, political orientation and more. With its long running panel...
