ARC ELASTICITY: The average elasticity for discrete changes in two variables, A and B. The distinguishing characteristic of arc elasticity is that percentage changes are calculated based on the average of the initial and ending values of each variable, rather than only initial values. Arc elasticity is generally calculated using the midpoint formula. Arc elasticity should be compared with point elasticity. For infinitesimally small changes in variables A and B, arc elasticity is the same as point elasticity.

POLICY LAGS Time lags that occur between the onset of an economic problem and the full impact of the policy intended to correct the problem. Policy lags come in two broad categories--inside lag (getting the policy activated) and outside lag (the subsequent impact of the policy). The three specific inside lags are recognition lag, decision lag, and implementation lag. The one specific outside lag is termed impact lag. Policy lags can reduce the effectiveness of business-cycle stabilization policies and can even destabilize the economy. Policy lags, especially inside lags, are often different for monetary policy than for fiscal policy.

Be on the lookout for vindictive digital clocks with revenge on their minds.
