Abstract

An emerging literature has demonstrated some unique characteristics of trade in differentiated products. This paper contributes to the literature by postulating that differentiated products may be subject to greater tariff evasion due to the difficulties associated with assessing their quality and price. Using product-level data on trade between Germany and 10 Eastern European countries during 1992-2003, we find empirical support for this hypothesis. We show that the trade gap, defined as the discrepancy between the value of exports reported by Germany and the value of imports from Germany reported by the importing country, is positively related to the level of tariff in 8 out of 10 countries. Further, we show that the responsiveness of the trade gap to the tariff level is greater for differentiated products than for homogenous goods. A one-percentage-point increase in the tariff rate is associated with a 0.4% increase in the trade gap in the case of homogenous products and a 1.7% increase in the case of differentiated products. Finally, the data indicate that while underreporting of quantities takes place for all products, only differentiated products are subject to misrepresentation of the import prices. There is no evidence of tariff evasion taking place through product misclassification.
