While the literature has established that there is substantial and highly selective return migration, the growing importance of repeat migration has been largely ignored. Using Markov chain analysis, this paper provides a modeling framework for repeated moves of migrants between the host and...

This paper investigates the time between transactions on financial markets. It is assumed that the interval between transactions is a random variable and the relationship between the probability to observe a transaction at each instant of time and the type of the previous trade is investigated....

We investigate executive turnovers with focus on different kinds of outside board memberships of supervisory board members. The analysis is based on all management board members of the largest German corporations during the period from 1996 to 2008. Cox proportional hazard estimations suggest...

We apply various refinements of survival regression to assess the results of some basic specifications based on product life cycle theory for the case of a data set of the German automobile industry. The methods applied pay attention to biases in the coefficient estimates and the standard...

The real options investment theory shows that greater uncertainty about market revenues reduces current Ramp;D investment by increasing the value of waiting. This paper presents empirical evidence that patent protection mitigates the effect market uncertainty on Ramp;D investment

Most of the empirical literature on the relationship between firm value and knowledge capital is based on the stock market valuation. We use a credit rating score as an alternative measure. Innovative firms with a reasonable knowledge stock achieve a better rating, whilst too many innovative...

Current literature argues that firms should have strong ties to customers to benefit from increased customer retention and loyalty. Strong ties, however, have also been shown to prevent innovation, suggesting that firms should also develop weak ties to other customer groups. This paper focuses...

This paper investigates the determinants of German long-term unemployment. In particular a microeconometric event history analysis will be carried out to examine what impact personal characteristics such as age, gender, education, etc. or factors such as receiving unemployment benefits have on...

This paper builds on the Empirical Monte Carlo simulation approach developed by Huber et al. (2013) to study the estimation of Timing-of-Events (ToE) models. We exploit rich Swedish data of unemployed job-seekers with information on participation in a training program to simulate placebo...

We use administrative social security records and event history methods to investigate graduate migration in Germany. The results indicate that most migration events happen up to seven years after graduation. Work experience gathered before and during the studies influences the migration...
