Despite a growing interest in cooperatives, the knowledge of real economic, occupational and social dimensions of the cooperative enterprises is still little and fragmentary, at both a national and an international level. This is also the case of Italy, a country with one of the most widespread...

Despite the growing interest in cooperative enterprise, our knowledge of the real economic, social, and employment size of the cooperative movement, both internationally and within individual countries, is scarce and fragmentary. In Italy over the years, a number of public bodies, institutions,...

This paper describes the role of social cooperatives in Italy as a type of economic, nonprofit organization that is assuming an increasingly central role in the country, by contributing to its economic and social growth. In the last decade many agencies, institutions and research centres (Istat...

In Italy, social cooperatives are an economic reality that is constantly expanding and plays an increasing role in the national economy. Social cooperatives are economic organizations of small-to-medium size that are strongly integrated into the local environment where they happen to develop....

This paper reviews a class of multifractal models obtained via products of exponential Ornstein-Uhlenbeck processes driven by L«evy motion. Given a self-decomposable distribution, conditions for constructiong multifractal scenarios and general formulas for their Renyi functions are provided....

We propose a stochastic model for the probability of default based on diffusions with given marginal distribution and autocorrelation function. The model tries to capture stylized features observed in historical default rates and is analytically tractable. Estimation procedures and expressions...

Continuous non-Gaussian stationary processes of the OU-type are becoming increasingly popular given their flexibility in modelling stylized features of financial series such as asymmetry, heavy tails and jumps. The use of non-Gaussian marginal distributions makes likelihood analysis of these...

Questo studio prende l'avvio da un'iniziativa di ricerca il cui obiettivo consisteva nella costruzione di un indice sintetico di dipendenza dell'anziano dalla struttura in cui è ospitato, veloce da calcolare e a basso costo. La variabile fondamentale usata nell'analisi è la quantità di tempo...

We provide a simulation procedure for obtaining discretely observed values of Ornstein-Uhlenbeck processes with given (self-decomposable) marginal distribution. The method proposed, based on inversion of the characteristic function, completely circumvent problems encountered when trying to...
