We study individual behaviour in a repeated linear public good experiment in which, in each period, subjects are required to contribute a minimum level and face a certain probability to be audited. Audited subjects who contribute less than the minimum level are convicted to pay the difference...

We develop a model where heterogeneous agents maximize their individual utility based on (after tax) income and on the level of public expenditure (as in Cowell, Gordon, 1988). Agents are different in risk aversion and in the relative preference for public expenditure with respect to personal...

Cost sharing represent a well-established tool for the control of health care demand in many Oecd countries, even though it is used with caution, and in combination with other instruments, in order to avoid potential negative impacts on access to essential health care services. Waiting lists and...

In this paper we show how both the choice of specific constraints on input and output weights (in accordance with health care policy-makers’ preferences) and the consideration of exogenous variables outside the control of hospital management (and linked to past policy-makers’ decisions) can...

This paper uses data from the Health and Retirement Study (HRS) to study the relationship between health status and economic welfare at household level. We develop a model to estimate the welfare cost of ill health by exploiting the methodology of the equivalence scales. The crucial variables in...

In this paper we present a model of tax compliance with heterogeneous agents who maximize their individual utility based on income and the conjectured level of per capita public expenditure. We formally include psychological drivers in this model. These drivers affect individual behavior, such...

The aim of the paper is to apply definitions and graphical devices currently used in the economic literature on poverty to individual data on tax evasion. Starting from simple indices, the paper presents composite indices and profiles of tax evasion and compliance, based on the three I’s of...

We study various methods of aggregating individual judgments and individual priorities in group decision making with the AHP. The focus is on the empirical properties of the various methods, mainly on the extent to which the various aggregation methods represent an accurate approximation of the...

The Analytic Hierarchy Process (Saaty 1977, 1980) is a decision-making procedure for establishing priorities in multi-criteria decision making. Underlying the AHP is the theory of ratio-scale measures developed by psychophysicist Stanley S. Stevens (1946, 1951) in the middle of the last century....

The Analytic Hierarchy Process (AHP) ratio-scaling approach is re-examined in view of the recent developments in mathematical psychology based on the so-called separable representations. The study highlights the distortions in the estimates based on the maximum eigenvalue method used in the AHP...
