Growth and social capital: an evolutionary model

In this paper, we analyze the role of cooperation between firms through a model of growth and social capital. In a growth model à la Solow we incorporate the set of resources that a relational network has at its disposals, as a distinct production factor, and thus examine its dissemination through evolutionary type processes in firm interactions. Dynamic analysis of the model demonstrates that cooperation is able to increase the productivity of factors, fostering a higher rate of growth in the long term. The most significant result is that scarcity of social capital can produce a general collapse of the economic system in areas in which long term growth is usually sustained by the learning by doing and spillover of knowledge phenomena. This conclusion leads to reconsider the role of local development economic policies that should concentrate on activities that promote repeated interaction between firms proven to be cooperative or that encourage the formation of technological consortia.     

Corporate governance and sustainability in water utilities. The effects of decorporatisation in the city of Naples,Italy

The recent economic literature has largely investigated sustainability in the provision of public utilities, highlighting the role of governance models in the determination of economic results. Little attention however has been devoted to the social and environmental dimensions of sustainability. In Italy, a long-lasting debate on governance structures in the water sector has been fuelled by scholars and policymakers for more than 30 years, whereas the first (and unique) experiment involving the return of full public management in water provision is taking place in the city of Naples. The present work analyses this peculiar case study, aiming to assess the effects of a major governance shift that occurred in the early 2010s—that is, decorporatisation—in terms of economic, social and environmental sustainability. We resort to a bundle of qualitative and quantitative techniques to address the research question and our exploratory results suggest that decorporatisation was overall beneficial: Although little changed in terms of economic sustainability, the social and environmental dimensions benefitted from the shift in governance.     

Political budget cycles and voting within a federal country: The influence of political alignment

We study how distributive politics affects political budget cycles and voting within a federal country. Our model predicts not only that the president favors politically aligned governors with larger transfers, but also that voters favor gubernatorial candidates aligned with the expected presidential incumbent because larger transfers are expected in the future. These predictions are upheld by the data from Argentinean provinces during the 1984–2014 period. Our findings imply that political alignment can trump the selection effect of voting the most competent candidate. This can help explain in particular coattail effects when gubernatorial and presidential elections are concurrent.     

Skills and labour incomes: how unequal is Italy as part of the Southern European countries?

This paper performs a comparative investigation of the effects of the Great Recession on the labour market structure and wage inequality in certain countries in Southern Europe (Greece, Italy, Portugal, and Spain). By exploring the intensity of the decline of middle-skill jobs during the years 2005–2013, which makes it possible to sketch what the labour market structure has set for itself (i.e., job polarisation, upgrading or neither), the objective is to relate these changes to wage inequality and its leading determinants. Through the Recentered Influence Function regression of the Gini index on EU-SILC data, Italy is compared to each selected country in order to evaluate how much of the spatial inequality gap is accounted for by the endowment in employee characteristics (composition effect) rather than the capability of each country’s labour market to reward these characteristics (wage structure) and, second, to identify those factors that are quantitatively more significant in making differentials. In brief, Italy is less unequal than the other Southern European countries. A larger amount of its “inequality advantage” depends on the wage structure. That is, the capacity of the country’s labour market in rewarding individual endowments is more important than the ways in which they are distributed across space.     

Gender pairings and accountability effects

We conduct an experiment to investigate how the gender composition of an audience interacts with the gender of a player thereby shaping her/his degree of responsibility in decision-making. Together with the measures of accountability based on decision theory, we employ two physiological measures, blood pressure and heart rate variability, which allow us to disentangle the separate effects of stress and accountability. Our results show that men are more sensitive to changes in the gender composition of the audience; specifically, men lower their accountability when paired with a female audience. By contrast, women display a level of accountability that does not change with gender pairing. Finally, we find that the variation in blood pressure has a significant but small effect only on men's behavior.     

The Chicago School after the crisis of the new millennium

After the self-criticism of Richard Posner (A failure of capitalism. The crisis of ’08 and the descend to depression. Harvard University Press, Cambridge, 2009a and some later papers), a position shared in part by Gary Becker, it is right to ask what exactly remains of the Chicago School, which came into being in the early 1930s with Knight and made a name for itself in the 1980s as the new orthodoxy with Lucas (Reh) and Fama (Emh). The financial crisis has, in this sense, cast the debate between the Saltwater school (the American universities on the coast) and the Freshwater school (the universities near the Great Lakes, including Chicago) in a new light. This article traces the development of the Chicago School, the consolidation of conservative think-tanks (especially the Mont Pelerin Society whose members have included, among others, von Hayek and Friedman) and the more recent positions of the School, including some that are less organic (Diamond, Kashyap, Rajan, Zingales). At the centre of the debate is the question of the failures of the State vs the failures of the market and the role of institutions. On a methodological level the relationship between law and economics (L&E) is also in discussion, which leads to an interesting comparison between Chicago (again Posner, past and present) and Yale (Calabresi). After having described the echoes of the debate across the Atlantic (with particular reference to Italy), it will be asked if the anomalies that can be found in the consolidated paradigm (Reh, Emh, but also L&E) will lead to the abandonment of pre-constituted models in favour of a less rigid theoretical framework (Ike together with Keynes and the Chicagoan Knight, but also to a certain extent, von Hayek) or simply a pause for reflection.     

Do institutions affect the matching process of disabled people? The Italian case

The aim of this paper is to investigate whether the various Italian regions’ efficiency in providing employment for disabled people under Law 12 March n.68 1999, “Regulation on the right to work of disabled people” (Law 68/99) can be affected by their institutional quality. For this reason, a Stochastic Frontier Approach is used for estimating the regional matching function, where the flow of disabled people who found a job is produced by the combination of unemployment and vacancies. The matching equation is estimated using regional data from ISFOL, from 2006 to 2011. Results show the presence of a territorial dualism with regard to the matching process. The Southern regions of Italy have the lowest efficiency scores due to their lower institutional quality. The empirical analysis confirms that a good institutional quality is able to reduce the inefficiency of the matching process of disabled people. Therefore, it requires the implementation of policies aimed at improving the level of institutions, particularly in Southern Italy, in order to improve the efficiency of Law 68/99.

     

Irreducible complexities: from Gödel and Turing to the paradigm of Imperfect Knowledge Economics

The paper discusses synthetically an epistemological question in the field of economics: how to translate a real problem into formal terms without a substantial loss of significance for its solution in policy making. The discussion will challenge the plausibility of the basic assumption of ultra-rational subjects who act independently of each other and will propose a research programme in Imperfect Knowledge Economics (in an Appendix the latter is compared with the mainstream model founded on Rational Expectation Hypothesis). References to some results of the debate in mathematics, but also in computer science, are produced in support.     

Analysis of regional productivity with capital as a quasi-fixed factor

Most existing studies of regional productivity growth do not incorporate the effect of variations in capacity utilization on changes in output. By failing to do so, their factor productivity estimates are biased. To overcome this shortcoming, we adjust multifactor productivity growth measure for changes in capacity utilization. Our technique recognizes that capital is a quasi-fixed factor which implies that capital in the short run can be either under- or over-utilized by a firm. Our results from 1974 to 1978 show that capacity adjusted multifactor productivity growth measure exceeds capacity unadjusted multifactor productivity growth measure for the nine census divisions. The bias in the capacity unadjusted measure of multifactor productivity growth is approximately 8 percent in East North Central and over 33 percent in Mountain. We find that the aggregate factor productivity growth is slowest in the traditional manufacturing belt (Middle Atlantic and East North Central divisions). The level of aggregate factor productivity in the manufacturing belt, however, is almost 33 percent higher than in regions in the south.
