In particular, After World War II, increasing public expenditure and budget deficits led countries to find permanent solutions. This need has been intensified with crises from Stagflation and budget deficits. First, the theory of financial rules emerged and applied in many countries. Following this, a stable public financial administration and independent financial institutions to ensure sustainable debt and deficits came up. Both methods have pros and cons. The aim of this study is to draw up an analysis by comparing these two methods and to develop a useful strategy for stabilising countries' long-term macro-physical dynamics.
