Access to OECD agricultural market: A gravity border effect approach

This paper uses the border effect estimate from a gravity model to assess the level of trade integration in agricultural markets between 22 OECD countries, over the 1995-2002 period. The empirical analysis shows that using a gravity equation derived from theory, in the estimation of the border effect, matters. A representative estimate of the border effect shows that crossing a national border into the OECD countries induces a trade-reduction effect by a factor of 8. This average value masks substantial differences in market access across the country groups considered, with higher value in trade between EU countries and lower in trade between CEEC countries. However, the trade integration between CEECs and others OECDs increases substantially in the observed period. Finally, the equivalent tariffs implied by the estimated border effects are not implausible when compared to the actual range of direct protection measures.
