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...

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...

The objective of this paper is twofold. First, against the background of an existing empirical literature on the duration of trade which has found that international trade is often of strikingly short duration, we aim to establish whether or not EU imports from the rest of the world also are...

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...

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 paper is to show why it is inappropriate to analyze the duration of trade with continuous-time models such as the Cox...

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...

The objective of the paper is to explore and give an overview of two central policy alternatives to improve the integration between the European Union and developing countries by removing barriers to trade: trade preferences and trade facilitation. After reviewing the relevant literatures and...

Since at least the 1960s, the European Union (EU) has offered various kinds of non-reciprocal trade preferences for developing countries. Originally, these trade preferences had at least two policy goals: (i) to increase export volumes for developing countries and thereby boost their export...

Since the 1960's, the EU has offered trade preferences to developing countries in a complex set of systems. Broadly these systems can be divided into preferences for African, Caribbean and Pacific (ACP) countries, Mediterranean preferences and the Generalised System of Preferences (GSP). We...

Exploring the link between trade facilitation and the extensive and intensive margins of trade, the paper has two aims. The first and main objective is to investigate whether the extensive margin of trade in homogeneous and differentiated goods is affected in the same way by cross-border trade...
