Inefficiency in the German Mechanical Engineering Sector

Schiersch, Alexander - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2009

This paper aims to examine the relative efficiency of German engineering firms using a sample of roughly 23,000 observations between 1995 and 2004. As these firms had been successful in the examination period in terms of output- and export-growth, it is expected that a majority of firms is...

Next Stop: Restructuring?: A Nonparametric Efficiency Analysis of German Public Transport Companies

Hirschhausen, Christian von; Cullmann, Astrid - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2008

In this paper, we present a nonparametric comparative efficiency analysis of 179 communal public transport bus companies in Germany (1990-2004). We apply both deterministic data envelopment analysis (DEA) and bootstrapping to test the robustness of our estimates and to test the hypothesis of...

Well-Being over the Life Span: Semiparametric Evidence from British and German Longitudinal Data

Wunder, Christoph; Wiencierz, Andrea; Schwarze, Johannes; … - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2009

This paper applies semiparametric regression models using penalized splines to investigate the profile of well-being over the life span. Splines have the advantage that they do not require a priori assumptions about the form of the curve. Using data from the British Household Panel Survey (BHPS)...

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

Nieswand, Maria; Cullmann, Astrid; Neumann, Anne - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2009

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...

Assets, Shocks, and Poverty Traps in Rural Mozambique

Giesbert, Lena; Schindler, Kati - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2010

Using a micro-level approach to poverty traps, this paper explores welfare dynamics among households in post-war rural Mozambique. Conceptually, the paper builds on an asset-based approach to poverty and tests empirically, with household panel data, for the existence of a poverty trap. Findings...

Are People Inequality Averse, and Do They Prefer Redistribution by the State?: Evidence from German Longitudinal Data on Life Satisfaction

Schwarze, Johannes; Härpfer, Marco - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2002

We link life-satisfaction data to inequality of the pre-government income distribution at the regional level, to … estimate the degree of inequality aversion. In addition, we investigate whether a reduction in inequality by the state … increases individual well-being. We find that Germans are inequality averse over the entire income distribution. However …
