ECONOMETRIC ESTIMATION OF THE GRAVITY MODEL OF EXPORTS: A CASE OF THE REPUBLIC OF UZBEKISTAN

In this article, the authors critically analyze the existing econometric approaches to estimating gravity models of exports from the point of view of solving such problems as taking into account zero observations, bias, inconsistency and inefficiency of estimates. As a result, the authors come to the conclusion that the method of Poisson pseudo-maximum-likelihood estimation (Poisson pseudo-maximum-likelihood, PPML) is the most preferable method for estimating the gravity export model of the Republic of Uzbekistan.
