The impact of consumer health information on the demand for health services

This paper empirically examines whether consumers use health information, from non-physician information sources, as a substitute or complement for health services – namely for physician visits and emergency room (ER) visits. An indicator of patient trust in physicians is developed and used as a proxy for potential unobserved heterogeneity that may drive both consumers’ propensity to seek information and to use physician services. The results, after correcting for sample selection bias and controlling for unobserved heterogeneity, concur with the literature, that consumer health information increases the likelihood of visiting a physician as well as the frequency of visits on average. However, low-trust consumers tend to substitute self-care through consumer health information for physician services. Further, better-informed consumers make significantly fewer ER visits suggesting that information may be improving efficiency in the market.     

Social cooperatives,social welfare associations and social networks

We use an original data-set to study how participation in two types of non-profit organizations – i.e. social welfare associations and social cooperatives – affects individual social capital, understood as a network of cooperative relationships. Participation in both the types of organization allows members to start new social relations. However, social welfare associations seem to play a significantly greater role in the development of volunteers’ social capital, favouring the creation of weak ties that are used to exchange information and advice, and offering the opportunity to establish stronger ties entailing concrete mutual support. Within social cooperatives, workers appear to develop their individual social capital to a greater extent than volunteers. Our results suggest that the composition of the workforce, the depth of members’ involvement in the organization’s activities and the human resources strategies adopted by the management influence the creation of cooperative relations through on-the-job interactions.     

Bowling alone but tweeting together: the evolution of human interaction in the social networking era

The objective of this paper is to theoretically analyze how human interaction may evolve in a world characterized by the explosion of online networking and other Web-mediated ways of building and nurturing relationships. The analysis shows that online networking yields a storage mechanism through which any individual contribution—e.g. a blog post, a comment, or a photo—is stored within a particular network and ready for virtual access by each member who connects to the network. When someone provides feedback, for example by commenting on a note, or by replying to a message, the interaction is finalized. These interactions are asynchronous, i.e. they allow individuals to relate in different moments, whenever they have time to. When the social environment is poor of participation opportunities and/or the pressure on time increases (for example due to the need to increase the working time), the stock of information and ties stored in the Internet can help individuals to defend their sociability.

Do cooperative enterprises create social trust?

This article contributes to the literature by carrying out the first empirical investigation into the role of different types of enterprises in the creation of social trust. Drawing on a unique data set collected through the administration of a questionnaire to a representative sample of the population of the Italian Province of Trento in March 2011, we find that cooperatives are the only type of enterprise where the work environment fosters the social trust of workers.     

Fairness and the Unselfish Demand for Redistribution by Taxpayers and Welfare Recipients

We theoretically illustrate how the aversion to unfairness triggers an unselfish though rational demand for redistribution. This leads the well-off to demand positive tax rates and the “poor” to reject extreme progressivity. We prove that the “rich” and the “poor” adjust their demand for redistribution in opposite ways when their sensitivity to fairness increases: while agents with above average expected income raise their demand for redistribution, agents with below average income lower it. We then provide empirical evidence of these behaviors using a nationally representative survey from Italy. The estimates confirm that a stronger aversion to unfair distributive outcomes is associated with a higher support for redistribution by individuals with high income and to a lower demand for redistribution by those with low income.     

Economic Growth,Technological Progress and Social Capital: The Inverted U Hypothesis

We set up a theoretical framework to analyse the role of economic growth and technological progress in the erosion of social capital. Under certain conditions on parameters, the relationship between technological progress and social capital can take the shape of an inverted U curve. Furthermore, we show the circumstances that allow the economy to follow trajectories where the stock of social capital grows endogenously and unboundedly.     

Online networks,social interaction and segregation: an evolutionary approach

There is growing evidence that face-to-face interaction is declining in many countries, exacerbating the phenomenon of social isolation. On the other hand, social interaction through online networking sites is steeply rising. To analyze these societal dynamics, we have built an evolutionary game model in which agents can choose between three strategies of social participation: 1) interaction via both online social networks and face-to-face encounters; 2) interaction by exclusive means of face-to-face encounters; 3) opting out from both forms of participation in pursuit of social isolation. We illustrate the dynamics of interaction among these three types of agent that the model predicts, in light of the empirical evidence provided by previous literature. We then assess their welfare implications. We show that when online interaction is less gratifying than offline encounters, the dynamics of agents’ rational choices of interaction will lead to the extinction of the sub-population of online networks users, thereby making Facebook and similar platforms disappear in the long run. Furthermore, we show that the higher the propensity for discrimination of those who interact via online social networks and via face-to-face encounters (i.e., their preference for the interaction with agents of their same type), the greater the probability will be that they all will end up choosing social isolation in the long run, making society fall into a “social poverty trap”.     

Media negativity bias and tax compliance: experimental evidence

We study the impact of the media negativity bias on tax compliance. Through a framed laboratory experiment, we assess how the exposure to biased news about government action affects compliance in a repeated taxation game. Subjects treated with positive news are significantly more compliant than the control group. Instead, the exposure to negative news does not prompt any significant reaction compared to the neutral condition, suggesting that participants may perceive the media negativity bias in the selection and tonality of news as the norm rather than the exception. Overall, our results suggest that biased news provision is a constant source of psychological priming and plays a vital role in taxpayers’ compliance decisions.
