The effectiveness of fiscal policies implemented in financial crises

Economic policies, which led to different grouping of economic ideas within the economic system and had a share in the separation of the economic literature into branches, gained the field of implementation in fluctuation circuits in the economic conjuncture. The fiscal policies, which are used as the most intervention tools in the global market from economic policies, have begun to be questioned by successive doctrines of the Vietnam War and Oil Crises, which began to be used in the Great Depression and the subsequent process. Fiscal policies, which were met with great doubt until the 2008 Crisis, have been widely used in many countries' economies to this day as the global crisis demonstrates the necessity of a social state. The financial and financial structure of the countries of the financial crisis, the consumption habits of the individuals in the economy, the expectations of actors involved in production and consumption, and the responses to the effectiveness of fiscal policy due to many factors such as risk management of sectors differ. It is determined that the effective fiscal policy tool differs in the example of each country in the literature, whether it is a public spending policy or tax revenues policy; In the study, finance policy was tested by taking advantage of Turkey's real GDP, total public expenditures and total tax revenues data for the period 2006:1-2019:4 as a country example. In the analysis conducted, it was determined that both the model in which the crisis effect was ignored and the model where the crisis effect was included, the fiscal policy was effective and the most effective fiscal policy tool for Turkey as the sample country is the government spending policy.
