Decision Lag is the time lag that it takes government leaders and policy makers to determine the appropriate government action needed to address an economic problem. The decision lag arises because it takes time for policy makers to chose among the array of possible policy actions, each with assorted consequences that appeal differently to different political constituencies. This "inside lag" is one of four policy lags associated with monetary and fiscal policy. The other two "inside lags" are recognition lag and implementation lag, and one "outside lag" is implementation lag. All four policy lags can reduce the effectiveness of business-cycle stabilization policies and can even destabilize the economy.
