This paper proposes a new bivariate competing risks model in which both durations are the first passage times of dependent Lévy subordinators with exponential thresholds and multiplicative covariates effects. Our specification extends the mixed proportional hazards model, as it allows for the...

Studies about innovation find evidence of a positive relationship between technological advancement and firm performance, in particular when the innovative effort is continuous. This paper aims to further the analysis on the duration of R&D investment at the firm level. The contribution of this...

Our analysis of the survival of firms leads to the important result that the hypotheses about differences between various industries in the life duration of new firms and about the importance of the region of location for the probability of survival are confirmed. Many more enterprises are...

In diesem Beitrag werden die Auswirkungen sektoraler, regionaler sowie betrieblicher Determinanten auf das Scheitern junger Betriebe mit Hilfe eines ökonometrischen Überlebensdauer-Ansatzes analysiert. Dabei findet ein accelerated failure time model mit zugrunde liegender log-logistischer...

Measuring economic uncertainty is challenging, but it is important for policymakers to address it, especially in countries for which there are virtually no uncertainty indices. This article proposes an index of economic uncertainty for Poland, EURQPL, based on Internet searches for specific...

This paper examines the determinants of mergers and bankruptcies, using firm level data from the Swiss Business Census and the Dun & Bradstreet exit database for Switzerland (1995-2000). Employing duration analysis, we find considerable differences in the determinants of mergers and...
