Heterogeneity of trade patterns in high-tech goods across established and emerging exporters: A panel data analysis

Abstract
This study aims to identify underlying fundamental factors behind high-tech exports by the established and emerging countries, separately. The author also examines whether the two export patterns converge over time. Based on the gravity approach, a generalized method of moments panel estimator is applied to rigorously address the endogeneity problem in both static and dynamic versions of the model. In addition, the nonstationary and cointegrating features of variables are discussed. The author finds that high-tech exports from the emerging countries are mainly based on foreign direct investment inflows and participation in the international production chain, as well as a high degree of...

Abstract
The extended gate concept aims to reduce the pressure on international ports by postponing administrative processes from these border gates to inland terminals. At present, this approach is used mainly in the container transport industry in European and Asian ports. In this paper we study an extended gate concept, where inland customs services are made available from all entry points of a country. Our aim is to predict the portion of the current flow through border gates that is diverted to these inland customs zones. We propose a time-series gravity models to predict these changes and estimate the parameters of this model using publicly available data for different cargo groups. The focus...
