Since its introduction to a wondering public in 1972, the Cox proportional hazards regression model has become an overwhelmingly popular tool in the analysis of censored survival data. However, some features of the Cox model may cause problems for the analyst or an interpreter of the data. They...

Using a proportional hazard model with multiple exits, this paper analyzes whether immigrants' unemployment spells differ from natives', and if so, how the difference vary with time spent in Sweden and across immigrant cohorts. A unique data set taken from the Swedish unemployment registers is...

The paper presents a discussion how firms rationally adjust the level of their recruitment effort in relation to the ease of filling the vacancy through public unemployment offices. This induces dependence between the durations in the two channels of recruitment. Multivariate models with random...

In this paper, we provide new evidence on how to model unemployment durations in the presence of temporary layoffs. Two different types of econometric models are used: the multiple phase duration model and the competing risks model. Special attention is paid to the possibility of time-varying or...

In the evaluation of efficacy of a vaccine to protect against disease caused by finitely many diverse infectious pathogens, it is often important to assess if vaccine protection depends on variations of the exposing pathogen. This problem can be formulated under a competing risks model where the...

This paper examines the determinants of exchange rate regime of a country. A competing risks model (CRM) is estimated. It is found that the way a country exits a fixed exchange rate regime is affected nonlinearly by the duration of the peg. In addition, countries with a lower growth rate of...

This paper examines the effect of innovation on the risk of exit of a firm, distinguishing between different modes of exits. Innovation represents a resource and a capability that helps a firm to build competitive advantage and remain in the market. At the same time, the resources and...
