This correspondence varies across states and time periods. In the article by means of econometric analysis it is shown that in 2006-2017 years marginal propensity of households to consume exceeded marginal propensity for goverment purchases in economy of Georgia. Because of this, aggregate demand was negatively dependent on avarage tax rate in Georgia during the discussed period of time.geaggregate demand; marginal propensity for goverment purchases; marginal propensity to consume; avarage tax rateEconometric analysis of the peculiarities of the impact of fiscal and monetary instruments on aggregate demand in the Georgian economyArticle
