In this equation, is the target short-term nominal policy interest rate (e.g. the federal funds rate in the US, the Bank of England base rate in the UK), is the rate of inflation as measured by the GDP deflator, is the desired rate of inflation, is the assumed natural/equilibrium interest rate, [9] is the actual GDP, and ¯ is the potential ...
The main policy to be avoided is countercyclical monetary policy, the standard Keynesian policy recommendation at the time. For this reason, the central bank should be forced to expand the money supply at a constant rate, equivalent to the rate of growth of real GDP.
Every level of the real interest rate will generate a certain level of investment and spending: lower interest rates encourage higher investment and more spending. The multiplier effect of an increase in fixed investment resulting from a lower interest rate raises real GDP. This explains the downward slope of the IS curve.
One such reaction function is the Taylor rule.It specifies the nominal interest rate set by the central bank in reaction to the inflation rate, the assumed long-term real interest rate, the deviation of the inflation rate from its desired value, and the log of the ratio of real GDP (output) to potential output.

Real GDP growth on an annual basis is the nominal GDP growth rate adjusted for inflation. It is usually expressed as a percentage. "GDP" may refer to "nominal" or "current" or "historical" GDP, to distinguish it from real GDP. Real GDP is sometimes called "constant" GDP because it is expressed in terms of constant prices.
As part of the decision, the Bank of Japan (BOJ) raised interest rates for the first time in 17 years, lifting its short-term rate to “around zero to 0.1%” from minus 0.1%, according to a ...
A social optimum occurs when the nominal rate is zero (or deflation is at a rate equal to the real interest rate), so that the marginal social benefit and marginal social cost of holding money are equalized at zero. Thus, the Friedman rule is designed to remove an inefficiency, and by doing so, raise the mean of output.
