An exploratory analysis of the relationship between social interactions, income and health in Italy

This paper carries out an exploratory investigation into the effect of various types of social interaction on health in Italy. After controlling for household income, education, work status and a number of socio-demographic variables, we find that the frequency of meetings with friends is significantly and positively associated with self-perceived health. The frequency of visits with relatives has a significant, but weaker effect. Membership in voluntary organizations is a significant and weakly negative predictor of good health. Other relevant explanatory variables are education and work status.Statistical matching, well-being, social interactions, social capital, health, Italy

Structural social capital and health in Italy

This paper presents the first empirical assessment of the causal relationship between social capital and health in Italy. The analysis draws on the 2000 wave of the Multipurpose Survey on Household conducted by the Italian Institute of Statistics on a representative sample of the population (n = 50,618). Our measure of social capital is the frequency of meetings with friends. Based on probit and instrumental variables estimates, we find that higher levels of social capital increase perceived good health.health; instrumental variables; income; social interactions; social capital; Italy

Quality and quantity: The role of social interactions in individual health

The public health literature focusing on the detrimental effects of social isolation has shown that the quantity of social connections is positively correlated with individual health. Drawing on pooled cross-sectional data, we test this hypothesis on a representative sample of the Italian population. Our findings show that, besides the quantity of interactions, it is their quality – as measured by subjective satisfaction derived from relationships with friends – that works as the best predictor of health. We point out the existence of health disparities based on socio-economic status. Poorer and less educated individuals are exposed to a higher probability of reporting poor health conditions. The risk is even worse for unemployed and retired workers. This paper contributes to the literature in two substantive dimensions. This is the first empirical study of the relationship between social interactions and health in Italy. Second, we add to previous studies by carrying out the first assessment of the role of satisfaction in interpersonal relations.Health, well-being, satisfaction, social interactions, social capital, family, Italy

The Political Economy of the Standard Level of Services: The Role of Income Distribution

The theory of fiscal federalism points out that decentralisation should be pursued in order to fit differences in individual preferences. However, the presence of externalities and the need of providing merit goods to citizens suggest that centralisation is likely to produce more efficient results. Moreover, in a political economy framework, each decision - including the possibility to fix a standard level of services - mainly depends on the objective function of the policymakers. Adopting this approach, the aim of this paper is to compare the individual convenience of a common standard level defined under a centralised system versus different provisions of public services when decisions are decentralised. Income heterogeneity across individuals is assumed.standard level of services, income concentration, decentralization, cooperative legislature

On Local Environmental Protection

We hereby propose a model to analyze the provision of environmental protection activities (United Nation 2005) with positive interregional externalities in order to verify - at least in theory - whether this kind of policy is better accomplished through centralized policymaking, which implies a coordinated solution among local representatives, or a decentralized system, whereby local authorities independently finance and implement their environmental protection policy. The research question concerns the identification of criteria on how to allocate powers and functions to environmental management at different tiers of government. Moreover, modelling interregional externalities as a mechanism contributing to lowering the cost of financing environmental policy in each region (production externality), we can assume that different environmental policies are allowed across regions. Given this general framework, considerations favouring either institutional setting in terms of individuals’ welfare seem to involve interaction among these key elements: the extent of the inter-jurisdictional spillovers, the size of local jurisdictions and the regional preferences for environmental protection policy.Environmental protection activities; Environmental federalism; Externalities; Local government

Free-riding or Internalizing? An Opportunistic View on Decentralization versus Centralization

The aim of the paper is to analyze a model of local public good provision with positive interjurisdictional spillovers comparing decentralized and centralized system. As in the recent Second Generation Theory (SGT) of fiscal federalism (Seabright 1996; Lockwood 2002, 2006; Besley and Coate 2003; Weingast 2009), we also adopt a political economy approach, assuming different behaviours of political leaders (Leviathan and non-Leviathan). The main contribution of the paper is to consider two relevant aspects neglected by the political economy models: the size of local jurisdictions and the explicit definition of the rent-seeking behaviour. Moreover, modelling interregional externalities as a mechanism contributing to lowering the production cost of the public good in each region, a different trade-off - from the traditional and new theory of fiscal federalism - is proposed in order to compare decentralized versus centralized solution: the gains from internalizing externalities and the losses of freeriding advantages, which may differ with regional size and preferences for the public good. Given this general framework, the convenience of decentralization versus centralization mainly depends on the interaction among these factors: i) the free-riding gains exploiting positive externalities; ii) the gains of internalizing externalities; iii) the degree of preferences heterogeneity; iv) the implicit transfers (“cross subsidization”) across different regions. To summarize, from a positive viewpoint, decentralization should not be necessarily pursued only in the absence of externalities, but also with high spillovers. The key insight of this result is represented by different size of regions, which may determine an asymmetry among citizens’ responses concerning the best institutional setting.decentralization, spillovers, free-riding, rent-seeking behaviour, local public goods

Can Market Power influence Employment, Wage Inequality and Growth ?

We introduce an efficiency-wage mechanism into an innovation-driven growth model. Due to informational problems, the labour market is segmented and homogeneous workers may be employed either in a non-competitive intermediate sector or in a competitive research one. We analyse the impact that variations in the monopoly power of the intermediate firms may have on unemployment, wage inequality and growth. We find that the lower the product market competition in the intermediate sector, the higher the research employment, the lower the intermediate sector employment, the higher the aggregate growth rate. Growth and inequality are negatively correlated whereas growth and unemployment are positively correlated. The last two results are obtained through numerical simulations.Efficiency wages; research and development; endogenous growth; market power
