An effective government initiative to lower the unemployment rate should be designed...

Past experience seems to show that when unemployment goes below the range we're in right now (click on the box) that prices go up because employers have too much difficulty in finding workers to meet demand.  Lower unemployment now will mean inflation and higher interest rates.

Maximum Employment
Maximum employment doesn't necessarily mean that everyone is working. Economists have a "natural rate" of unemployment that is ultimately the goal. If the unemployment rate is pushed too low -- below 5% or so -- inflation rises because more money is in the economy, and that goes against the long-term Fed goal of stable prices.
