Behavior of Brazilian Commercial Relationship for Hardwood Lumber Explained With Gravitational Equation

Abstract

The aim of this study was to explain the dynamics of Brazil's hardwood lumber exports. The database containing information regarding the sales of hardwood lumber between 1997 and 2010, distance between Brazil and its hardwood lumber importers, a dummy variable indicating the contiguity, GDP and GDP per capita of the countries that bought hardwood lumber from Brazilian was analyzed. The fitted equation showed r 2 =63.65% and all the variables were significant. This equation showed that countries with bigger economies import more Brazilian hardwood lumber than countries with small economies. Besides, the negative signal on the adjusted parameter associated with the distance shows that the imported quantity for the countries is inversely proportional to distance. The gravitation model explained Brazil's sawn hardwood exports. KEYWORDS: Exports of sawn timber. International commerce. Brazil.
