This paper analyses the relationship between past innovation output, competition, and future innovation input in a dynamic econometric setting. We distinguish two dimensions of competition that correspond to the concepts of product substitutability and entry barriers due to fixed costs. Based on...

This paper exploits the introduction of the right of referenda at the local level in the German state of Bavaria in 1995 to study the fiscal effects of direct democracy. In the first part of the paper, we establish the relationship between referenda activity and fiscal performance by using a new...

Dieser Beitrag nimmt aus theoretischer und ökonometrischer Sicht zu der Kontroverse über die Bedeutung der qualifikatorischen Lohnstruktur zur Erklärung der Beschäftigungsstruktur Stellung. Basierend auf einer Einteilung in drei Qualifikationsgruppen zeigt sich empirisch, dass die Entlohnung...

In order to reduce unemployment, it is often recommended that industry-level wage bargaining in Germany should be replaced by a more decentralized system. This paper provides a critical assessment of the current wage bargaining institutions and reexamines the case for a more decentralized...

We develop a simple model of competition for the market that shows that, contrary to the Arrow view, endogenous entry threat in a market induces the average firm to invest less in R&D and the incumbent leader to invest more. We test these predictions with a Tobit model based on a unique dataset...

Quantile regression methods are emerging as a popular technique in econometrics and biometrics for exploring the distribution of duration data. This paper discusses quantile regression for duration analysis allowing for a flexible specification of the functional relationship and of the error...
