    Adaptation to Income over Time: A Weak Point of Subjective Well-Being

    This article holds the view that intertemporal comparisons of subjective well-being measures are only meaningful when the underlying standards of judgment are unaltered. This is a weak point of such measures. The study investigates the change in the satisfaction judgments resulting from adaptation to income over time. Adaptation is defined to be desensitization (sensitization) to the hedonic effect ...

    Time and Income Poverty: An Interdependent Multidimensional Poverty Approach with German Time Use Diary Data

    Income as the traditional one dimensional measure in well-being and poverty analyses is extended in recent studies by a multidimensional poverty concept. Though this is certainly a progress, however, two important aspects are missing: time as an important dimension and the interdependence of the often only separately counted multiple poverty dimensions. Our paper will contribute to both aspects: First, ...

    The Contribution of Local Public Infrastructure to Private Productivity and Its Political Economy: Evidence from a Panel of Large German Cities

    This paper proposes a simultaneous-equation approach to theestimation of the contribution of infrastructure accumulationto private production. A political economy model for theallocation of public infrastructure investment grants isformulated. Our empirical findings, using a panel of largeGerman cities for the years 1980,1986, and 1988, suggest thatcities ruled by a council sharing the State (`Bundesland')government's ...

    Entry Regulation and Entrepreneurship: Empirical Evidence from a German Natural Experiment

    The amendment to the German Trade and Crafts Code in 2004 offers a natural experiment to asses the causal effects of this reform on the probabilities of being self-employed and transition into and out of self-employment, using cross-sections (2002-2006) of German microcensus data. This study applies the difference-in-differences technique in logit models for four occupational groups. Easing the educational ...

    Occupational Affiliation Data and Measurement Errors in the German Socio-Economic Panel

    This paper shows that there are severe measurement errors regarding the occupational affiliations in the German Socio-Economic Panel. These errors are traced back to the survey structure: in years where occupational information is gathered from the entire employed population instead of only from those declaring job or labor market status changes, average occupational mobility is around five times higher. ...

    Estimating Income Poverty in the Presence of Missing Data and Measurement Error

    Reliable measures of poverty are an essential statistical tool for public policies aimed at reducing poverty. In this paper we consider the reliability of income poverty measures based on survey data which are typically plagued by missing data and measurement error. Neglecting these problems can bias the estimated poverty rates. We show how to derive upper and lower bounds for the population poverty ...

    The Cross-Section of Output and Inflation in a Dynamic Stochastic General Equilibrium Model with Sticky Prices

    In a standard dynamic stochastic general equilibrium framework, with sticky prices, the cross sectional distribution of output and inflation across a population of firms is studied. The only form of heterogeneity is confined to the probability that the ith changes its prices in response to a shock. In this Calvo setup the moments of the cross sectional distribution of output and inflation depend crucially ...

    Overcoming Data Limitations in Nonparametric Benchmarking: Applying PCA-DEA to Natural Gas Transmission

    We empirically demonstrate a practical approach of efficiency evaluation with limited data availability in some regulated industries. We apply PCA-DEA for radial efficiency measurement to U.S. natural gas transmission companies in 2007. PCA-DEA reduces dimensions of the optimization problem while maintaining most of the variation in the original data. Our results suggest that the methodology reduces ...

    SOEP as a Source for Research on Ageing: Issues, Measures and Possibilities for Improvement

    Demographic change is a key consequence of the development of modern societies. The prolongation of life expectancy, shifts of mortality into later life and long-term low fertility rates cause essential changes in population structures - with an increase in the number and proportion of older people as a key feature. The changes in mortality patterns can be seen as a success of modern society. But demographic ...
