Introduction. Economic cycles, the periodic emergence of economic imbalances, deep economic crises, the need for effective management of economic fluctuations have created the need to develop an effective mechanism for anti-cyclical economic regulation. As a result of the in-depth study of these problems, it has been established that the most effective instruments of anti-cyclical economic regulation are financial instruments owned by the state and divided into monetary and fiscal ones. They in turn are divided into discretionary and non-discretionary, and regulated by legislative acts and regulatory documents.
As a result of a retrospective analysis of management of economic cycles through the use of financial means of the state, it has been proved that monetary policy is less sustainable than economic fiscal policy. On the contrary, for the last century, precarious monetary policy has caused many financial and economic upheavals; the world has seen at least three monetary and monetary systems that have been subject to a downturn every time. Therefore, it is not worth considering monetary policy sufficiently effective in the implementation of anti-cyclical regulation.
While fiscal policies each time, in all economic crises, have played the role of a "lifeline" for countries that have taken anti-cyclical economic regulation measures.
That is why the study of the problem of effective state management of socio-economic fluctuations is one of the most urgent issues of economic science.
The goal of the work. To investigate the essence of monetary and fiscal instruments of counter-cyclical regulation of the economy, to identify their strengths and weaknesses, to propose effective mechanisms of counter-cyclical regulation of the economy, which would ensure economic development in the country.
Methods. In the course of the research, general scientific and empirical methods of economic science based on a systematic approach are used, in particular: methods of scientific knowledge: dialectical and logical, analysis and synthesis, generalization, graphical, scientific abstraction - in the study of state financial policy in the field of anti-cyclical regulation of the economy.
Results. The article deals with the essence of monetary and monetary systems, analyzes their weak and strong sides, identifies the causes of their decline. It was established that monetary factors influenced the emergence of centers of economic crises.
The essence of fiscal policy, its types and models, and the way in which its instruments influence the course of the economic cycle are considered and deeply analyzed. The mechanisms of fiscal policy, which should be used by the state at different stages of the economic cycle, are singled out. It is proved that in economically developed countries during the economic crisis it is expedient to use a socially-oriented model of fiscal policy of acyclic nature that most effectively influences the overcoming of economic imbalances and is capable of ensuring the economic equilibrium in the country as soon as possible. Countries that effectively applied the liberal model of fiscal policy, in the conditions of the economic crisis, were forced to resort to transformation towards a more rigid fiscal intervention by the state in economic processes-they were forced to use socially-oriented, acyclic fiscal policies. Only the wider participation of the state in the regulation of economic processes have ensured the rapid and effective overcoming of economic crises, and contributed to the achievement of economic development in most countries of the world.
Perspectives. The results of scientific research can be useful for scientists and practitioners who are engaged in research on problems of anti-cyclical regulation of the economy, state financial policy and, in particular, fiscal policy.
