The Efficiency of the Macroeconomic Policies


In the present work, the authors aim to determine the efficiency of the macroeconomic policies by determining the effects of the application of the instruments (revenue change) and finding out the instrument having the highest efficiency.

In today’s macroeconomic theory and practice, the efficiency level of the macroeconomic policy instrument is measured using multipliers. The different nature of the measurement units used when calculating the multipliers makes it impossible to compare the multipliers in order to establish the more efficient instrument, and for this reason it becomes necessary to use elasticity as an efficiency indicator.
