Exploring the Long-Term Evolution of Trade Survival Wolfgang Hess and Maria Persson


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 extended time period that we study: in general only 40 percent of trade flows survive the first year of service, and this share has not changed much since the 1960s. However, this observed constancy is the result of two underlying trends that work in opposite directions. On the one hand, positive trends in several of the observed explanatory variables – which in turn influence the hazard of trade flows dying in a negative direction – imply that the hazard tends to decrease over calendar time. On the other hand, there is also a positive trend in the hazard due to calendar year-specific unobserved factors. Holding all observed determinants constant, the probability of a trade flow dying in its first year increases from 34% at the beginning of the period to 90% at the end.

The European Union in a Changing World Order

This book explores how the European Union responds to the ongoing challenges to the liberal international order. These challenges arise both within the EU itself and beyond its borders, and put into question the values of free trade and liberal democracy. 

About the book

Events

Seminars organized by IFN

 

To present ongoing research informal brown-bag seminars are held on Mondays at 11:30 am. This is an opportunity for IFN researchers to test ideas and results.

Academically oriented seminars are most of the time held on Wednesdays at 10 am. At these events researchers from IFN and other institutions present their research.

In addition, IFN organizes seminars open to the public. Topics for these are derived from the IFN research.
