On a Gravity Equation of Trade: A Case of Germany and the Czech Republic

Popis výsledku v původním jazyce

Since 1960s gravity models or equations (economic analogies of Newtons Law of gravity) of various kinds are used in modeling volumes of international trade with a significant statistical success. These models assume that a volume of a bilateral trade ispositively proportional to sizes of trading economies and negatively proportional to their distance. The aim of the paper is to evaluate exports from Germany (the 3rd world exporter) and the Czech Republic (small and open post-transition economy used fora comparison) to their international partners via frictionless aggregate gravity equation with the use of the latest (2012) export data. Results of linear regression with corrected heteroscedasticity (for both countries separately) indicate that the model predicts exports successfully with adjusted determinacy coefficients around 0.75 (GER) and 0.98 (CZE) respectively. Also, coefficients associated with the gross domestic product (0.60 and 0.65) and distance between countrie s (1.24 and
