This article argues that the consequences of the ‘fragmentation’ of the European patent system are more dramatic than the mere prohibitive costs of maintaining a patent in force in many jurisdictions.

Data envelopment analysis and panel data stochastic frontier models are used to evaluate the impact of the 1995 renewal of regional political institutions and the 1998 tax reform (introduction of IRAP) on the efficiency of Italian regional governments.

A coalition within the Parliament,...

This paper explores for the first time the consequences of centrally imposed local tax limitations on the modelling and estimation of spatial auto-correlation in local fiscal policies, and compares three spatial interaction estimators: a) the conventional maximum likelihood estimator that ignores censoring; b) a spatial Tobit estimator; c) a discrete...
