Consolidating the Water Industry: An Analysis of the Potential Gains from Horizontal Integration in a Conditional Efficiency Framework

Zschille, Michael - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2012

The German potable water supply industry is regarded as being highly fragmented, thus inhibiting high potentials for efficiency improvements through consolidation. Focusing on a hypothetical restructuring of the industry, we apply Data Envelopment Analysis (DEA) to analyze the potential...

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)...

Potential Gains from Mergers in Local Public Transport: An Efficiency Analysis Applied to Germany

Walter, Matthias; Cullmann, Astrid - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2008

We analyze potential gains from hypothetical mergers in local public transport using the non-parametric Data Envelopment Analysis with bias corrections by means of bootstrapping. Our sample consists of 41 public transport companies from Germany's most densely populated region, North...

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 …
