Statistical Analysis in surveys is often facing missing data. As case-wise deletion and single imputation prove to have undesired properties, multiple imputation remains as a measure to handle this problem. In a longitudinal study, where for some missing values past or future data points might be available, the question arises how to successfully transform this advantage into better imputation...

Lack of transmission capacity hampers the integration of the European electricity market, and thereby precludes reaping the full benefits of competition. We investigate the extent to which transmission grid expansion promotes competition, efficiency and welfare. This work proposes a three-stage model for grid investment: a benevolent planner decides on network upgrades, considering welfare...

We estimate the deterrence effects of EU merger policy instruments over the 1990-2009 period. Our results suggest that phase-1 remedies uniquely involve robust deterrence in the European context, as they lead to fewer merger notifications in subsequent years. Furthermore, merger-policy actions as a whole – as well as preventions, phase-2 remedies, and phase-1 withdrawals – do not appear to yield...

In recent years several German large-scale panel studies demonstrated the demand for the coding of open-ended survey questions on respondents’ occupations (e. g. the National Education Panel Study (NEPS), the German Socio-Economic Panel (SOEP), and the Panel Study “Labour Market and Social Security” (PASS)). So far occupational coding in Germany is mostly done semi-automatically, employing...

A growing proportion of employees are working under fixed-term contracts. This paper empirically analyzes whether this strategy actually improves firm productivity. To this end, a largedata set of German manufacturing firms and various panel data models are used in order to reveal the expected non-linear effect. Thereby the analysis also takes into account distortions that may result from...

This paper proposes a theoretical framework of strategic alliances that includes two observable dimensions of participating partners which have been identified in the literature as critical for success or failure. In particular, we first propose a simple static theory that links the degree of alliance partners' complementarities with the intensity of their competition in product markets. We show...
