WHY DO UNDERGROUND REDUCING POLICIES OFTEN FAIL THEIR SCOPE? SOME ANSWERS FROM THE ITALIAN EXPERIENCE

Several European countries, facing a sizeable underground economy, often adopt underground reducing policies mainly based on incentives in the tax-benefit system. Since empirical evidence manifests a substantial failure of such policies, we construct a simple model to indicate the crucial aspects of this failure. To this end we consider a tax-evading firm, allocating work in the official and underground sector, where it is not taxed. With a view to reducing underground employment, the government may decide to launch an amnesty for past social security noncompliance, while providing fiscal incentives for new hiring in order to encourage a process of worker regularization. Allowing for endogenous enforcement, we find that the reputation of policy-makers in combating tax evasion proves crucial in determining the success of such a policy.
