The paper provides a unifying framework for conducting Bayesian inference on the presence of seasonal and zero frequency unit roots in quarterly data. The main technique used is the analysis of posterior odds ratios. A new parameterization is provided for the model and the prior distributions...

Unemployment durations are generally modelled by specifying the conditional probability of leaving unemployment (the hazard function). Existing studies for Britain all use very restrictive parametric specifications of the hazard function, mostly commonly Weibull in form. These restrictions...

From individual-level longitudinal data for two entire cohorts of medical students in UK universities, we analyze the probability that an individual student will ‘drop out’ of medical school prior to the successful completion of their studies. We examine the cohort of students enrolling for...

In this paper we set up a general duration model of technology adoption which incorporates the main factors discussed in the different side theories if diffusion of new process technologies. The model is applied to the data on diffusion of CNC in the UK engineering industry. It is found that...
