A Choice Modelling (CM) experiment is designed to analyze the relation between Non-Use Values (NUVs) and distance. This issue is relevant in environmental valuation as it can help to identify the relevant market for a given environmental asset and improve individual benefit estimates. The CM...

This paper describes a Choice Modelling experiment set up to investigate the relationship between distance and willingness to pay for environmental quality changes. The issue is important for aggregation and transfer of benefits. So far the problem has been analysed though the use of Contingent...

Mutual funds classifications, often made by rating agencies, are very common and sometimes criticized. In this work, a three-step statistical procedure for mutual funds classification is proposed. In the first step time series funds are characterized in terms of returns. In the second step, a...

One of the main problems in modelling multivariate conditional covariance time series is the parameterization of the correlation structure because, if no constraints are imposed, it implies a large number of unknown coefficients. The most popular models propose parsimonious representations,...
