Compare between the cost of inflation, and the cost of unemployment, and it's effect to the economy ?

Answer 1

The cost of inflation is mostly a theoretical concept and attempts to estimate it empirically give inconsistent results which depend on the time period. Here is a recent paper on the subject. http://fmwww.bc.edu/ec-p/wp662.pdf
Most economist think that deflation is more costly in terms of real output and the fed tries to keep the inflation level a small positive number.
The cost of unemployment is the number of unemployed X productivity per worker, where the productivity can be estimated to be 1.5 to 2 times the median wage.
