We explore origin–destination forecasting of commodity flows between 15 Spanish regions, using data covering the period from 1995 to 2004. The 1-year-ahead forecasts are based on a recently introduced spatial autoregressive variant of the traditional gravity model. Gravity (or spatial...

The existence of a large border effect is considered as one of the main puzzles of international macroeconomics. We show that the border effect is, to a large extent, an artefact of geographic concentration. In order to do so we combine international flows with intranational flows data...

The Heckscher-Ohlin-Vanek (HOV) model in its strict form has been strongly rejected by the data. Relaxing some assumptions of the standard HOV model is key to find improvements in its performance. We apply the Davis and Weinstein (2001) methodology to analyse the validity of the HOV model using...

Recent empirical papers testing the performance of the Heckscher-Ohlin-Vanek (HOV) model suggest the need to relax its restrictive assumptions in order to reconcile the theory with the data. This paper examines whether introducing factor productivity differences could help to improve the...
