The Future Flow of Goods in the Enlarged EU Ole Kveiborg & Stéphanie Vincent Lyk-Jensen Danish Transport Research Institute The future flow of goods in the enlarged EU
Contents • Motivation • Overall methodology • From trade flows to freight flows • Data • Empirical specification of the model • Results • For Western European countries • For Central and Eastern European countries • Conclusion The future flow of goods in the enlarged EU
Motivation • Globalisation, EU enlargement • Congestion, optimisation of public investments, Road pricing, sustainable transport • Research project for the Danish Ministry of Transport and Energy The future flow of goods in the enlarged EU
Objective of the project • Prediction of bilateral freight flows between all European Countries • Method? The future flow of goods in the enlarged EU
Existing Freight Flows (tons/year) European Trade Flows (US $ / year) Gravity Model 1967 - 2002 Transport Forms and Route Choice( SENEX ) 2000 Conversion Growth Rates 2000 - 2025 US $ tons Commodity Group. Scenario Analysis 2025 Transport Form and Route Choice( SENEX ) 2025 The principle The future flow of goods in the enlarged EU
Growth in trade vs. growth in tons The future flow of goods in the enlarged EU
Growth per commodity s.t. The future flow of goods in the enlarged EU
Data • Sample: EU15 + 2 EFTA countries : 16 countries • Period 1967-2002 • All economic variables are in constant prices (USD 1995) • Distance: great circle distance from capital to capital • Source: CHELEM, CEPII The future flow of goods in the enlarged EU
Growth in real GDP and trade 550 250 Source CHELEM database The future flow of goods in the enlarged EU
Econometric approaches • Error Component Model • Fixed Effects Model (FEM) • Three-way model with time and country effects (3-way) • Dynamic The future flow of goods in the enlarged EU
Econometric Approaches • Fixed Effects Model (FEM) Trade flow effect Time effect • 3-way model with time and country effects Mátyás (1997): Export country effect Import country effect Time effect The future flow of goods in the enlarged EU
Econometric approaches Static vs. dynamic • Problem: • Model with lagged value of the dependent variable is biased • Order of the bias for a FEM is 1/T Baltagi (1995) • Solution (Judson and Owen, 1999): • For T<30 years ; Use Generalized Method of Moment (GMM) instead of the Least Squares (LS) estimation to correct for the bias The future flow of goods in the enlarged EU
Results for EU15-EFTA countries The future flow of goods in the enlarged EU
Central and East European Countries (CEEC) • Problems: • Not relevant to estimate a model with the CEECin the period 1993-2002 • How to take the integration process into account? • Solutions: • Use the estimation based on the ”EUEFTA” sample • Keep the dynamic formulation • Estimate fixed effects for these countries The future flow of goods in the enlarged EU
Trade in 2025 Regional distribution of trade The future flow of goods in the enlarged EU
Changes in import and export (tons) The future flow of goods in the enlarged EU
Import by region and goods type (ton) The future flow of goods in the enlarged EU
Total increase in tons on the road network Total change on the road network(tons per year) The future flow of goods in the enlarged EU
Tons in transport to CEEC The future flow of goods in the enlarged EU
Conclusion • Method for forecasting future freight flows • From volume of trade to tons • Allocatethe growth per commodity group • Introduce the growth rates into the freight model • Results similar to TEN STAC (2003) • Show the changes in road network • Indications of future capacity problems The future flow of goods in the enlarged EU
