OUTSIDE LAG: In the context of economic policies, the time between corrective government action responding to a shock to the economy and the resulting affect on the economy. This is one of two primary lags in the use of economic policies. The other is inside lag, the time between a shock to the economy and corrective government action responding to the shock. The length of the outside lag, also termed impact lag, is primarily based on the speed of the multiplier process and is essentially the same for both fiscal and monetary policy. The length of the inside and outside lags is one argument against the use of discretionary policies to stability business cycles.

Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.
