The aim of this study was to analyze the impact of the 2008 financial crisis on Paraná´s exports through Gravity Model. The Gravity Equation estimated used as the dependent variable the exports of Paraná and as independent variables the Gross Domestic Product (GDP) and population of the state, GDP and population of importers countries of products from Paraná, the distance in kilometers between the state´s capital and the capital of the importer country, commodities prices in the international market, the area of importers countries and the dummies crisis, China, NAFTA, European Union and MERCOSUR. The Equation was estimated using panel data models by Pooled, Fixed Effects and Random Effects. The tests of Chow, Hausman and Breusch-Pagan LM indicated that the best model to be analyzed is the Random Effects. The tests of Breusch -Pagan and Wooldridge indicated, respectively, the presence of heteroscedasticity and autocorrelation. Thus, the Random Effects model was estimated with heteroscedasticity correction, with correction for autocorrelation and both fixes. According to the Equation estimated by the Random Effects model with heteroscedasticity and autocorrelation correction, the variables GDP and population of Paraná, GDP and population of importers countries and commodities prices were statistically significant and their coefficients showed, with the exception of the Paraná´s GDP, a positive relationship with the Paraná´s exports. The variables distance and area of importers countries were statistically insignificant and their coefficients showed an inverse relationship with exports of Paraná. The dummies China, NAFTA, European Union and MERCOSUR were statistically insignificant. Their coefficients showed a positive relationship between the Paraná´s exports and China and MERCOSUR and negative with NAFTA and the European Union. The dummy crisis was statistically significant, indicating that reduction in demand caused by the global financial crisis led to a reduction of 11,68% in Paraná´s exports. However, between 2008 and 2009, the Paraná´s exports fell by 26,3%. Thus, the occurrence of crisis partially explained the drop in exports of Paraná between 2008 and 2009. This can be explained by non-tariff barriers imposed by countries in response to the financial crisis.
