Abstract
ABSTRACT Lack of interregional trade data is often a major obstacle when doing economic analysis at the subnational level. This paper discusses a calibration procedure for estimating bilateral trade between the regions of a country. Our approach can be equivalently characterized as an application of the gravity-RAS or the doubly constrained gravity model method. Either way, a crucial element is represented by the distance elasticity parameter, which the user is expected to provide exogenously. We propose a way of estimating that parameter using standard econometric methods with readily available data and demonstrate our calibration procedure in a case study of Italy.
期刊介绍:
Spatial Economic Analysis is a pioneering economics journal dedicated to the development of theory and methods in spatial economics, published by two of the world"s leading learned societies in the analysis of spatial economics, the Regional Studies Association and the British and Irish Section of the Regional Science Association International. A spatial perspective has become increasingly relevant to our understanding of economic phenomena, both on the global scale and at the scale of cities and regions. The growth in international trade, the opening up of emerging markets, the restructuring of the world economy along regional lines, and overall strategic and political significance of globalization, have re-emphasised the importance of geographical analysis.
