Concerning: unemployment and inflation

Dear professors,

It takes time to get things published, so I overcome my hesitations and send you enclosed paper. It is one of the fruits of 15 years of econometric research, including long term projections with 2000 equations models.

The paper gives a structural analysis of unemployment, regardless the state of inflation. The analysis can be extended on the time path of inflation.

You should read it with a good intuition of the importance of heterogeneous labour and a reduced form analysis.
