This paper analyzes the empirical literature that examines the effects of fiscal policy shocks on economic activity. Discussion related to fiscal policy is related to the impacts on economic growth is quite current, because the development of appropriate fiscal instruments can lead to steady and sustainable economic growth in the countries. The role of fiscal policy and the impact on economic activity are among the most controversial issues among academics and policymakers. In the absence of any "active" intervention in government expenses, tax revenues move automatically with the economic cycle. I can also say that government transfers can be considered as help for the unemployed, they grow as the economy slows down and unemployment rises, while labor tax returns, capital and consumption flows are declining. Resistive actions occur when the business cycle improves. In recent years, empirical studies have shown that private consumption and GDP have increased significantly, while government expenses have been severely reduced. Most empirical evidence suggests that fiscal expansion increases production and consumption and worsens the trade balance.The Kenzie and Neoclassical schools have different views on the impact of public spending on economic activity. This study has completed a detailed review of many important, relevant scientific havepapersthat empirically document these impacts. As a conclusion, we can state that although the fiscal policy theory is well developed, until recently has not received much attention from the (applied) economic practice. The first category is aimed at assessing macroeconomic impact from major reductions in the budget deficit, and the second study, in general, analyzes the stabilizing capabilities of fiscal policy variables. According to Blanchard and Perotti, the dynamic effects of the discretionary fiscal policy of macroeconomic variables have recently focused on the omissions of autoregressive vectors (2002). Some empirical studies have found a link between budget deficits, money growth and inflation, both in industrialized economies as well as in growing economies. For industrial economies most of these studies have come to the conclusion that there is little evidence that government debt affects the growth of money and inflation. In developing countries, it is often argued that high inflation is realized when governments face large and ongoing deficits financed by money emission. A change in taxes or public expenses (the so-called “fiscal shocks”) at any time prevents their development.
