This paper compares different versions of the simulated counterparts of the Wald test, the score test, and the likelihood ratio test in the multiperiod multinomial probit model. Monte Carlo experiments show that the simple form of the simulated likelihood ratio test delivers the most favorable...

A problem statistical offices and research institutes are faced with by releasing micro-data is the preservation of confidentiality. Traditional methods to avoid disclosure often destroy the structure of data, i.e., information loss is potentially high. In this paper I discuss an alternative...

Für Unternehmensdaten existieren im Gegensatz zu Personendaten keine einheitlichen Regeln zur Erstellung von Scientific-Use-Files, d.h. eines anonymisierten Datenfiles zur wissenschaftlichen Nutzung. Verschiedene Anonymisierungsmethoden werden hier vorgestellt. Um Mikrodaten einer breiten...

Although explanations of the persistence of high unemployment in Germany, in particular long-term unemployment, have increasingly focused on structural factors, there is only very limited evidence on their empirical importance so far. In this paper, these factors are analyzed based on a...

Academic spin-offs are one way in which employability of university graduates is reflected. Using the ZEW spinoff-survey, this paper studies empirically the impact of human capital on the success of academic spinoffs founding in knowledge and technology intensive sectors. The focus is thereby on...
