    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 ...

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

    This paper provides an empirical demonstration for a practical approach of efficiency evaluation against the background of limited data availability in some regulated industries. Here, traditional DEA may result in a lack of discriminatory power when high numbers of variables but only limited observations are available. We apply PCA-DEA for radial efficiency measurement to US natural gas transmission ...

    Duration of Maternity Leave in Germany: A Case Study of Nonparametric Hazard Models and Penalized Splines

    The paper investigates maternity leave behavior in West Germany for females being employed between 1995 and 2006 using data from the German Socio Economic Panel. The observational study focuses on the investigation of individual and family-related covariate effects on the duration of maternity leave following first or second childbirth, respectively. Dynamic duration time models are used in which covariate ...

    Produktdiversifizierung: Konvergenz zwischen ost- und westdeutschen Unternehmen: eine Dekomposition mit Mikrodaten der amtlichen Statistik

    In the aftermath of Germany's reunification, redesigning their product range was a major challenge for East-German enterprises. At the same time, there were growing signs that Western enterprises reacted to globalization and European integration by increasingly pursuing strategies of specialization. Using representative micro data from Germany's system of register based, official firm surveys, this ...

    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 Marginal Utility of Income

    In normative public economics it is crucial to know how fast the marginal utility of income declines as income increases. One needs this parameter for cost-benefit analysis, for optimal taxation and for the (Atkinson) measurement of inequality. We estimate this parameter using four large cross-sectional surveys of subjective happiness and two panel surveys. Altogether, the data cover over 50 countries ...

    Where Are the Industrial Technologies in Energy-Economy Models? An Innovative CGE Approach for Steel Production in Germany

    Top-down computable general equilibrium (CGE) models are used extensively for analysis of energy and climate policies. Energy-intensive industries are usually represented in top-down economic models as abstract economic production functions, commonly of the constant-elasticity-of-substitution (CES) or translog functional form. This study explores methods for improving the realism of energy-intensive ...

    Quality of Life in Rural Areas: Processes of Divergence and Convergence

    In Germany, processes can be observed that have long been out of keeping with the principle of equality of opportunity. Unemployment is concentrated in the structurally weak peripheral areas, in Eastern Germany in particular; emigration of young and better-educated people to the West is not diminishing, but contrary to expectation is again on the increase; aging processes have set in already, and when ...

    Does Job Satisfaction Improve the Health of Workers? New Evidence Using Panel Data and Objective Measures of Health

    This paper evaluates the relationship between job satisfaction and measures of health of workers using the German Socio-Economic Panel (GSOEP). Methodologically, it addresses two important design problems encountered frequently in the literature: (a) cross-sectional causality problems and (b) absence of objective measures of physical health that complement self-reported measures of health status. Not ...
