I) Welfare Economics and Keynesian Macroeconomics
a) A general theory of welfare under uncertainty
b) The philosophical aspect of Keynesian macroeconomics
c) The rational behaviours of a policy-maker
The different theories of Welfare Economics are analysed according to their ethical aspects and uncertainty. By considering competitive moral and social systems, the main aim is to give an answer to the following question: From the point of view of rationality, what characteristics should a general theory of welfare have?
The philosophical aspect of J. M. Keynes macroeconomics are analysed in order to understand why his theory cannot be represented by models which consider a social welfare function to be maximised.
The different rational behaviours of economic agents are analysed according to the quantity of information available. Specific attention has been given to the rational behaviour of a policy-maker.
II) Natural resources management: Cost-Benefit Analysis; Contingent valuation method
d) The sustainable management of natural resourses
e) Estimate of a tourist demand for a coastal site in
the Emilia-Romagna region
f) Estimate of the willingness to pay (WTP) for a
biodiversity conservation project of two parks in the
g) Estimate of the WTP for a project about the reduction of
flooding risk in Venice (Italy)
h) Estimate of the WTP for a defence project from erosion of
the Riccione and Misano Adriatico beaches
i) Estimate of the willingness to pay for the conservation of eroded beaches according to the Integrated Coastal Zone management approach.
l) Estimate of the willingness to pay for benefits about the implementation of projects for reducing the risk of flooding
The study of natural resourses management has been conducted by applying the theory of Cost-Benefit Analysis which asks that social benefits and costs are evaluated by valuation methods such as the Contingent valuation method. In some researches funded by the EU and the Ministero della Ricerca e Istruzione the Contingent valuation method has been applied in order to estimate social benefits from the implementation of public projects. A multidisciplinary approach has been applied. This method has been applied to population samples of national and international sites. Regression models are applied according to the different characteristics of the data so obtained in order to find out the main determinants of these social benefits. The main models used are: Tobit
model, Probit and ordered probit, and the Amemyia model.
A research about the willingness to pay of populations living in sites under risk of flooding and emission of pollution is in progress.
