Since the seminal work of Oates (1972) on scal federalism, a central question of public finance has been which level of a federation should be as- signed the provision of public goods. In this paper we study the problem of a government that is to choose the optimal...

In this note we explore the welfare properties of the cost effectiveness criterion as an instrument to improve the appropriateness of health care. We show that such instrument is optimal only under specific assumptions relating to the shape of the welfare function and the utility of health care.

Public service provision has undergone a significant process of reform through the reduction of vertical integration in its supply and the introduction of competition. The aim of these reforms is to increase efficiency and ultimately to improve welfare, but these goals can be reached only if the...

In this note we explore the welfare properties of access restrictions to health care based on cost effectiveness. We show that such instrument can improve the average effectiveness of health care, but it is optimal only under specific assumptions relating to the shape of the welfare function and...

Two ingredients seem essential in understanding the patient-physician relationship: (i) the physician's informational advantage and (ii) the relevance of the patient's emotions. Health economics has placed great emphasis on the first phenomenon, whereas the second has been considered only...

An abnormal expansion of the public sector may create serious problems to the market economy, as the literature suggests. This issue is quite important in countries such as Italy where the size of the public sector and of its debt are quite relevant. In this paper a model, in the microeconomic...

In this article, we analyse the optimal investment decision in a new health care technology of a representative hospital that maximises its surplus in an uncertain environment. The new technology allows the hospital to increase the quality level of the care provided, but the investment is...

In a recent article Davidson, Lawrence and Wilson propose a model showing that, in the presence of distortionary taxations and goods of different quality, tax evasion can be an optimal device. Here, we show that this result, although quite interesting, cannot be generalised to a framework where...

This paper examines the effects that tax evasion has on the cost to produce goods and service in an environment where input prices are homogenously taxes, but evasion is intersectorially differentiated. Tax evasion raises the relative cost of producing goods and services in the sectors where...
