Price relations analysis of export in the Czech republic

A common export equation is used to describe the Czech export of machinery, tradable goods, agricultural and food products, and income from the tourist industry. Four important export regions are distinguished: Slovakia, Poland, Germany and USA. The problem of small data sample, which is a characteristic one for most time series of the Czech economy, is solved here by using the seemingly unrelated regression. The results confirm the theoretical expectation of more efficient estimates in comparison with the OLS variant. The basic characteristics of export are given with regard to the commodities and to the regions in question.
