This paper estimates the effects on the Greek export performance that caused by the EU
accession. A simultaneous equations model of export demand and export supply has been
used in order to avoid the simultaneity problem. Comparative static analysis and the residuals
approach have been implemented. The results indicate that the EU accession and the
consequent abolition of the export subsidies had a negative effect on the country?s export
performance, instead of improving it. The main reason for this effect is that the export
subsidies, during the time period that were valid, were just improved the exporters? revenues
and not used for creating new comparative advantages for the Greek products.
