Testing the Model of Endogenous Growth in the Economy of Republic of Croatia (1960-2002)

Abstract

In this paper relevant time series are study for empirical test of AK model of endogenous growth of the economy of Republic of Croatia. We used contemporary method of time series, testing of unit root and analyses of cointgration regressions. For that purpose research give consideration to characteristics of time series of growth of gross investments, rate of openness and economic growth of Republic of Croatia in the long period (1960-2002). The aim of article is to demonstrate that evidence of stationary in the time series exists. By this it could be accepted AK model of endogenous growth which predicted that the growth of active fixed assets (or physical capital) in the economy is perpetuating the economy growth in Croatia. The results indicating that the permanent changes in the rate of economic growth and rates of investments of Croatia exist because the rates of growth in given time intervals is stationary. The essential conclusion of the paper is that the presence of cointegration through the cointegration equations of regressions and relevant variables in the long term is not proved. Because of this validity of basic AK model of endogenous growth can be denied in a way that the growth of gross investment in Croatia will cause the permanent growth of output.
