Relation to inflation

The theories behind the Phillips curve point to the inflationary costs of lowering the unemployment rate. That is, as unemployment rates fell and the economy approached full employment, the inflation rate would rise. But this theory also says that there is no single unemployment number that one can point to as the "full employment" rate. Instead, there is a trade-off between unemployment and inflation: a government might choose to attain a lower unemployment rate but would pay for it with higher inflation rates. In essence, in this view, the meaning of “full employment” is really nothing but a matter of opinion based on how the benefits of lowering the unemployment rate compare to the costs of raising the inflation rate.
