This article questions the slope homogeneity in a gravity equation and proposes a partially heterogeneous framework for its estimation using panel data. We suggest to employ K-mean clustering to group countries according to the gravity equation variables. Further, the gravity model is estimated...

The paper applies the gravity model of international trade in its analysis of German exports. The added value of our research is derived from the innovative shift in focus from the traditional gravity model specifications to the national level in order to interpret its estimations in a...

The paper re-examines the validity of the hysteresis hypothesis by applying it to the UK import volume from the world's five largest economies: Germany, France, Italy, Japan and the USA, over the period 1975 to 1994. Disaggregated bilateral data (4- digit ISIC) are used and hysteresis is...

The paper tests for potential pricing-to-market for a wide range of export industries in selected transition economies, namely Poland, Hungary and Bulgaria, at the four-digit level over the period 1990-1998. Panel estimation is undertaken and a fixed-effects linear model is estimated. The...

The paper initiates a new area of research: both concepts of hysteresis and pricing-to-market are simultaneously investigated in relation to German exports into Belgium, France, Italy, UK, Spain and Sweden over the period 1975 to 1994 at 4-digit ISIC level. There is abundant empirical evidence...

An emerging literature on international activities of heterogeneous firms documents that exporting firms are more productive than firms that only sell on the national market. This positive exporter productivity premium shows up in a large number of empirical studies after controlling for...

This paper makes three contributions. (1) It summarizes in tabular form a recent literature made of 36 micro-econometric studies for 16 different countries on the relationship between export destination and firm performance. (2) It reports estimates of the productivity premium of German firms...

In empirical studies it often happens that some variables for some units are far away from the other observations in the sample. These extreme observations, or outliers, often have a large impact on the results of statistical analyses – conclusions based on a sample with and without these...
