3 Basic Conclusions 1. No such thing as a simple scal multiplier! The response of the economy to discretionary scal stimulus depends on a number of factors.. The model simulations based on the Global Integrated Monetary Fiscal Model (GIMF) suggests that the G stimulus will have important e ects on global. Without this stimulus, the model suggests that global would be signi cantly weaker in 9 and 1. Same conclusions when we look at other structural models from the Fed, ECB, EC, OECD, and Bank of Canada.

4 Strengths of GIMF OLG set up means that increases in government debt will have permanent e ects on net foreign liabilities and real interest rates Large menu of scal instruments Can study scal and monetary policy issues in the same model; good for short-run and long-term analysis which is essential for understanding scal issues

6 Multipliers from Temporary Changes in Fiscal Instruments The change in the scal instrument is calibrated to generate a change in expenditures or revenues equal to 1% of baseline in year 1 and.5% in year. The multiplier is measured simply in terms of real as a percent deviation from the baseline. It is assumed there is a coordinated global monetary policy response. Monetary policy is determined by an interest rate reaction function, where interest rates are allowed to either adjust freely, or are held xed for two years.

7 Why is it Critical to Examine the Multipliers under Monetary Accommodation? Timely scal expansions are critical when there are risks of de ation and the policy rate is at the zero interest rate oor. In a situation where scal stimulus is designed to help exit from a recession, scal multipliers should be expected to be larger than during periods when monetary and scal policies are working at cross purposes and central banks are raising interest rates to o set the expansionary and in ationary implications of a scal expansion.

8 The Seven Fiscal Instruments 1. increase in government consumption.. increase in government investment. 3. increase in general lumpsum transfers.. increase in transfers targeted to hand-to-mouth consumers. 5. decrease in labour tax revenue collection.

9 . decrease in consumption tax revenue collection. 7. decrease in corporate income tax revenue collection.
