Neoclassical versus Technological Convergence: Some Evidence from the Recent Experience of the Italian Regions
by Carluccio Bianchi, Mario Menegatti pages: 17 € 6.00
This paper tests for the existence of neoclassical and/or technological catching up across Italian regions in the last three decades. The test is performed making use of a model based on the decomposition of output growth, similar to that proposed by Dowrick - Rogers (2002). The results imply that while the neoclassical convergence mechanism has occurred, the technological mechanism has failed. A possible explanation of the evidence found is that the regions initially endowed with better technology were subsequently characterised by a greater number of innovations and a higher share of GPD spent on research expenditure, which enabled them to maintain a substantial technological gap. These results suggest the policy conclusion that complete convergence across Italian regions requires the promotion of technological transfers and an increase in R&D expenditure in the least developed regions.
Aspettando il 2011: riflessioni su qualita` e uso dei risultati del Censimento demografico
by Gian Carlo Blangiardo pages: 16 € 6.00
After reviewing the novel aspects characterising the last four population censuses and how researchers have exploited their results, we present some thoughts about the 2011 Italian population census. Whilst calling for more accurate and accessible contents and results of the survey, we focus our attention on the rather controversial issue regarding the procedure and mode of data acquisition. Do we need to confirm the traditional (universal and simultaneous) survey, or can we try new procedures, even if this means to combine information from administrative registries and surveys? This is a dilemma that calls for an accurate evaluation of the advantages and drawbacks related to the different hypothesis in each of the two cases. The experiences of 1991 and 2001, which included surveys of foreigners and the temporary residents, demonstrated that results do not always follow the effort and reflect the expectations. Innovations are welcome, but only if they do not compromise the quality and details of the census information gathered.
Measuring poverty within and between population subgroups
by Enrica Chiappero-Martinetti, Marisa Civardi pages: 16 € 6.00
In this paper we propose a decomposition of the Foster, Greer, Thorbecke (FGT) class of poverty indices into two components (namely, poverty within groups and poverty between groups) when both a community-wide threshold and a specific poverty line for each subgroup of population is used. The aim is to suggest an integrated perspective that takes into account both poverty within a specific subgroup of the population and poverty between different subgroups. This allows us to throw light on the relative well-being conditions of specific subgroups of the population as well as of society as a whole. The paper also includes an empirical application of the suggested methodology based on the European Community Household Panel.
Human Development in the EU
by Flavio Delbono, Diego Lanzi pages: 11 € 6.00
In its present formulation the Human Development Index (HDI) is a measure of the well-being of nations considering two fixed reference values for each indicator, the so-called fixed goals of development, as normalization parameters. As is well known, the HDI is insensitive to the relative performance of a country with respect to those of a reference group of nations. Nevertheless, several recent works on individuals’ perception of their well-being reveal that subjective well-being is positively correlated with upward mobility opportunities and negatively correlated with the persistency of well-being inequalities within a reference group. Therefore, in this paper, we suggest an easy-tohandle extension of the HDI aimed at integrating the «absolute» perspective implicit in the traditional index with a relative one. Finally, as an application of our index, we assess the well-being of nations in the EU.
A closed form Ramsey path
by Massimiliano Ferrara, Luca Guerrini pages: 8 € 6.00
In this paper we generalize the result obtained by Mehlum (2005) by deriving an explicit solution for the path within a Ramsey model with fixed-proportion technology, CIES utility function and logistic-type population growth.

Concorrenza di prezzo, essenzialita` ed esternalita` di rete in presenza di beni complementari: nuove soluzioni alla «Tragedia degli Anticommons
by Matteo Alvisi pages: 24 € 6.00
The presence of multiple sellers in the provision of (non-substitutable) complementary goods leads to outcomes that are worse than those generated by an integrated monopoly, a problem also known as the «tragedy of the anticommons». In this paper we identify some conditions under which the tragedy is resolved and under which a complementary oligopoly is preferable to a multiproduct monopoly. First, we introduce several substitutes for each complement and determine their minimum number for the result to hold. Second, we study asymmetric complementarity and the presence of essential goods, stressing the role of the degree of differentiation across substitutes for the persistence of the «double mark-up» problem. Third, we verify whether the inefficiency result holds in dynamic terms, discussing the adoption of new technological standards in complementary oligopolies. The focus will be on indirect network externalities, checking under which conditions an inefficient standard emerges or the market becomes «locked in» in an old standard.
