We study a simple exogeneity test in count data models with possibly endogenous multinomial treatment. The test is based on Two Stage Residual Inclusion (2SRI). Results from a broad Monte Carlo study provide novel evidence on important features of this approach in nonlinear settings. We find...

We investigate whether people enrolled into voluntary health insurance (VHI) substitute public consumption with private (opt out) or just enlarge their private consumption, without reducing reliance upon public provisions (top up). We study the case of Italy, where a mixed insurance system is in...

In this paper we assess the relative effectiveness of user charges and administrative waiting times as a tool for rationing public healthcare in Italy. We measure demand elasticities by estimating a simultaneous equation model of GP primary care visits, public specialist consultations and...

Each year about 20% of the 10 million hospital inpatients in Italy get admitted to hospitals outside the Local Health Authority of residence. In this paper we carefully explore this phenomenon and estimate gravity equations for "trade" in hospital care using a Poisson pseudo maximum likelihood...
