Uobičajena je praksa da se prilikom iskazivanja uspešnosti nacionalne ekonomije, kao mera privredne aktivnosti koristi stopa ekonomskog rasta. Sa tim u vezi, postizanje visokih i stabilnih stopa privrednog rasta nameće se kao ultimativni cilj, naročito u zemljama u razvoju. Kako bi se unapredila dinamika rasta, neophodno je adekvatno upravljanje faktorima koji ga determinišu. Modeliranje povezanosti ključnih makroekonomskih varijabli je od višestrukog značaja, u kontekstu dinamiziranja stopa privrednog rasta. Predmet doktorske disertacije odnosi se na ispitivanje ključnih faktora koji generišu privredni rast. Predmet istraživanja je usmeren i na utvrđivanje potencijalnih veza makroekonomskih varijabli i ekonomskog rasta. U fokusu pažnje se nalaze instrumenti monetarne i fiskalne politike, odnosno njihova uloga u postizanju makroekonomske stabilnosti i osnaživanju performansi rasta. Osnovni cilj istraživanja jeste da se na bazi relevantne teorijsko-metodološke i empirijske analize, ispita statistička značajnost i jačina uticaja odgovarajućih determinanti privrednog rasta na ukupnu ekonomsku aktivnost. Teorijskom analizom i empirijskim testiranjem osnovnih modela privrednog rasta, ustanovljeno je da humani kapital, reprezentovan u vidu ulaganja u obrazovanje, kao i sektor za istraživanje i razvoj, predstavljaju generatore privrednog rasta kako u razvijenim, tako i u zemljama u razvoju. Pored toga, na primeru Republike Srbije je pokazano da je održivi ekonomski rast u dugom roku, moguć na bazi povećanog udela investicija u strukturi agregatne tražnje, pri čemu veći udeo istih treba da bude baziran na domaćim izvorima finansiranja. Imajući u vidu da ekonomska politika predstavlja neophodan instrument za postizanje makroekonomske stabilnosti, na primeru Republike Srbije su ispitani efekti monetarne i fiskalne politike na privredni rast, dok je na primeru zemalja Jugoistočne Evrope ispitana međuzavisnost ključnih makroekonomskih pokazatelja. Ključni rezultat modeliranja m, It is a common practice to use economic growth rates as a measure of economic activities when the performance of a national economy is to be presented. Thus, the ultimate goal, especially for developing countries, has been to achieve high and stable economic growth rates. Such goals can be reached only by adequately managing the factors which determine the growth. The modelling of relations among key macroeconomic variables has numerous advantages. The doctoral dissertation aims at examination of key macroeconomic variables which influence economic growth and to determine their potential links. The main emphasis is on the instruments of monetary and fiscal policy and their role in achieving macroeconomic stability and enhancing growth performances. The main goal of the research is to determine statistical significance and strength of impact which the determinants of economic growth have based on the overall economic activity with relevant theoretical, methodological and empirical analysis. Theoretical analysis and empirical testing have shown that human capital, represented as investments in education, research and development sector, are generators of economic growth in both developed and developing countries. In addition, the research has shown that in case of the Republic of Serbia sustainable long-term economic growth is possible with an increased share of investments in the structure of aggregate demand when such an increase is based on domestic sources of financing. Since economic policy is a necessary instrument for achieving macroeconomic stability, the study has examined the effects of monetary and fiscal policy on economic growth on the example of the Republic of Serbia while the interdependence between macroeconomic indicators has been examined in case of the countries of Southeast Europe. The main finding of the modeling of macroeconomic variables is the positive impact of inflation on economic growth both in short and long term. Thus the monet

Poslednje decenije ovog veka obeležile su promene pa rticipacije sektrora u ekonomskom razvoju kojima je tercijarni sektor do bio na značaju. Sektor koji je permanentno bio zapostavlj en i čiji je uticaj bio minimiziran, postao je lokomotiva ekonomsko g prosperiteta, naročito u razvijenim tržišnim ekonomijam a. Međusektorska preraspodela ekonomskog uticaja dinamičkog j e karaktera. Na početku ljudskog razvoja najznačajniji je b io primarni sektor sa poljoprivredom kao dominantnom gran om delatnosti. Prva industrijsko - tehnološka revolucija uslovi la je da na značaju dobije sekundarni sektor sa teškom industrijom kao vodećom granom, a najnovija, treća tehnološka revolucij a gde su nosioci razvoja kompjuterska tehnologija sa informacijom ka o osnovnim razvojnim resursom, doprinela je prosperite tu servisnog sektora koji se direktno bavi proizvodnjom, obradom i ra zvojem informacija. Tehnološki napredak nije pozitivno delovao isključivo n a razvoj tercijarnog sektora, jer ne postoji delatnost u svakom o d tri sektora koja u sebi ne uključuje informaciju kao resurs. Stoga ne postoji bojazan da će razvijene tržišne ekonomije postati servi sna, uslužna društva sa zapostavljenim primarnim i sekundarni m sektorom. Pre bi se moglo govoriti o novim načinima zaj edničkog tržišnog delovanja i sektora međuzavisnosti koja je dan as izraženija nego ikada, bez obzira na povećani uticaj tercijarnog sektora., Last decades of this century have brought about chang es in the sectors participation in economic development by which t ertiary sector assumed greater importance. The sector which has b een permanently neglected, and whose influence has been mi nimized, became a locomotive of the economic prosperity, part icularly in developed market economies. Intersectoral redistribution of economic influence has dynamic characteristic. In the very beginning of the human deve lopment the primary sector with agriculture as dominant activit y was the most important one. First industrial and technological revolution attributed greater importance to the secondary (indus trial) sector with heavy industry as a leading branch, and new third technology with information as a main development resource has b rought prosperity to the tertiary sector which directly produces, processes and develops information. Tehnological progress has not positively influenced o nly the tertiary sector but the others as well since there is no activity in either of the three sectors which does not include info rmation as a resource. Therefore there is no worry that developed market economies will become service producing societes that disr egard the primary and secondary sectors. It is rather a quest ion of new methods of the joint market action and sectoral interd ependence which is today more expressed than ever, regardless of an increased impact made by tertiary sector.
