As our understanding of genetics has increased, so has the number of genetic tests that have entered clinical practice. Given the need of many European health care systems to contain costs, the question of how to prioritise genetic tests fairly has become an emerging concern.

When analyzing panel data using regression models, it is often reasonable to allow for time-varying covariate effects. We propose a novel approach to modelling timevarying coefficients in panel data regressions, which is based on penalized regression techniques. To illustrate the usefulness of...

We employ spatial econometrics techniques to investigate to what extentcountries’ economic and geographical relations affect their stock market comovements.We propose an econometric model that is particularly suitable for financial data, where common time trends prevail. In general, among the...

Multi-state transition models are widely applied tools to analyze individual event histories in the medical or social sciences. In this paper we propose the use of (discrete-time) competing-risks duration models to analyze multi-transition data. Unlike conventional Markov transition models,...

The recent literature on the duration of trade has predominantly analyzed the determinants of trade flow durations using Cox proportional hazards models. The purpose of this article is to show why it is inappropriate to analyze the duration of trade with continuous-time models such as the Cox...

In the existing literature, the duration of trade has typically been analyzed using either descriptive Kaplan-Meier methods or a Cox regression approach. While the latter has the advantage of allowing for explanatory variables, it is designed for the analysis of continuous duration times,...

This paper proposes a discrete-time hazard regression approach based on the interrelation between hazard rate models and excess over threshold models, which are frequently encountered in extreme value modelling. The proposed duration model incorporates a grouped-duration analogue of the...

Aiming to explore how the survival of trade flows has evolved over time, we analyze a rich data set of detailed imports to individual EU15 countries from 140 non-EU exporters, covering the period 1962–2006. We find that short duration is a persistent characteristic of trade throughout the...
