This paper proposes a new coefficient for measuring economic valuation based on utility scores and attribute importance values derived from standard conjoint analysis. The coefficient allows to quantify the impact of a change in an attribute of a good or service in monetary terms. We utilize the suggested coefficient for the economic valuation of a worldwide cultural event to reveal the trade-offs among its attributes in terms of total revenue variation. In addition, our findings indicate how the user degree of satisfaction affects the determinants of demand in generating an economic surplus or shortfall

When close equals groups are used for decomposing the redistributive effect of taxation, it arises the issue related to the choice of a proper bandwidth. Recent literature (Kim and Lambert, 2008; Urban and Lambert, 2008) suggests to set the bandwidth for close equals groups to maximize the vertical effect measure in accordance with van de Ven, Creedy and Lambert’s suggestion (van de Ven et al., 2001). But the close equals methodology proposed by Urban and Lambert differs from the van de Ven, Creedy and Lambert’s one. Then the choice of the bandwidth still involves a sensitivity analysis of the decomposition results. In this work we recall the various decomposition methods and, following Vernizzi and Pellegrino (2007) approach, we select the bandwidth by comparing the behaviours of the alternative vertical components over a wide bandwidths range. We consider a micro data set derived from AMeRIcA Data Warehouse which collects pre-tax and post-tax incomes of residents in the Milanese area. Our findings show that for the selected bandwidth all the alternative measures of vertical effect explain a potential redistribution.

This paper presents the opportunities for measuring taxation effects by using combined administrative data from AMeRIcA Data Warehouse. Data combination provides demographic and income information on individuals and families resident in the Milanese area thereby permitting the evaluation of the impact of tax reforms on a specific taxpayer type as well as the simulation of the application of various tax systems. In our analysis we shall concentrate on Milanese families and we measure the impact of five different tax systems in force during 2005 from various European countries (France, Germany, Ireland, Italy and Spain).
