This paper provides a full technical description of a variant of the Italian General Equilibrium Model (IGEM), a dynamic general equilibrium model used as a laboratory for policy analysis at the Department of the Italian Treasury. This version of IGEM presents four specific key features: (i) imperfectly competitive final good sector; (ii) involuntary unemployment; (iii) a business tax bearing on firms; (iv) market frictions in
the labor market of atypical workers.
The paper presents some simulation scenarios of structural and fiscal reforms.
