Term impact lag Definition: 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 four lags in the use of economic policies. The others are recognition lag, decision lag, and action lag. The length of the impact lag, also termed outside 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 policy lags is one argument against the use of discretionary policies to stability business cycles.
