We introduce a model of proportional growth to explain the distribution $P(g)$ of business firm growth rates. The model predicts that $P(g)$ is Laplace in the central part and depicts an asymptotic power-law behavior in the tails with an exponent $\zeta=3$. Because of data limitations, previous...

We study size and growth distributions of products and business firms in the context of a given industry. Firm size growth is analyzed in terms of two basic mechanisms, i.e. the increase of the number of new elementary business units and their size growth. We find a power-law relationship...

SaniRegio is an econometric model, based on fixed effects panel techniques, that investigates the level of efficiency of Italian Regions in governing their health care systems. As a result of the model, we obtain a measure of the efficient or standardized expenditure that may be compared to the...

CeRM recommendation for creating a new tool, the Open Welfare Funds: open funds based on real capitalisation of contributions, dedicated to both pension and health care provisions, and linked to collective insurance coverage against major health risks (first of all lack of self-sufficiency)...

The paper first develops Region-based mid-long term projections of public health care expenditure for Italy; then wonders about the most appropriate rule for financing it, distinguishing between its efficient part and the part absorbed by inefficiencies of regional governments. The first part...
