Conceptul modelului econometric al economiei naționale a Republicii Moldova

Abstract

The elaboration of the econometric model is an iterative process that includes several steps. The model that is used to analyze and forecast the main macroeconomic indicators of the economy of the Republic of Moldova is a system of simultaneous equations; there the endogenous factors in some regression of the model can serve as exogenous factors. This leads to failure of basic assumptions of LS estimation method of each regression in part and that leads to inefficient, inconsistent and biased estimators. In the article is presented a general scheme of the macroeconometric model of the national economy and the methods that is used to overcome problems of estimating the model’s regression. The process of research simplifies, if the model is divided into blocks of simultaneous equations and blocks with recursive equations.
