Social sciences and neuroscience: a circular integration

Social phenomena can be described and explained through different levels of analysis, which correspond to the theoretical and methodological domains of different disciplines. According to a hierarchy of disciplines which moves from high-order to low-order levels, collective phenomena should be grounded on individual mental processes which, in turn, should rely on brain processes. The crucial question is whether the neuroscientific account of brain processes can be conceived as equivalent to the psychological account of mental processes. It is argued against the complete equivalence of the two kinds of accounts. However, it is maintained that a specific contribution can derive from each discipline so to provide an advance in understanding. It is questioned which could be the better way for psychology and neuroscience to inform each other. It is suggested that knowledge coming from the two disciplines, rather than being simply juxtaposed, should be integrated so to allow each discipline to give and receive insight to/from the other one.     

Alliances and negotiations

Negotiations often occur not between individuals but among groups (companies, trade unions, political parties, etc.) each representing composite interests, whose bargaining behaviour is regulated by some collective decision mechanism. In this paper we provide a natural model of such circumstances. We formalise the notion of ‘alliance’ and show how different preference aggregation procedures within the alliance affect the bargaining outcome. In particular, we find that unanimity procedures lead to ‘more aggressive’ negotiating tactics than majority procedures.     

The relationship between food consumption, age and gender over time in Britain

This paper investigates the relationship between nutrition and socio-economic status among British youths. It describes the dynamics of consumption over age and time using data from the British National Food Survey (NFS) covering the period 1975-2000. Daily calories-age relationships for men and women are estimated by solving a non-linear least square model with a roughness penalty function approach. Focusing on young age groups, trends of consumption over the 25-year period of study and the cohorts effect have been explored across three classes of age. Finally, an exploration of specific trend variations in eating habits has been implemented controlling for income distribution.     

TRUST,VALUES, AND FALSE CONSENSUS

Individuals’ beliefs about the trustworthiness of a generic member of the population are both heterogeneous across individuals and persistent across generations. We investigate one mechanism yielding these dual patterns: false consensus. In the context of a trust game experiment, we show that the relationship between behavior and beliefs is consistent with individuals extrapolating their trust beliefs from their own trustworthiness and that this tendency continues even after substantial learning opportunities. We go on to provide evidence suggesting that one's own trustworthiness can be traced back to the values parents transmit to their children during their upbringing.     

Efficient monetary allocations and the illiquidity of bonds

We construct a monetary economy with heterogeneity in discounting and consumption risk. Agents can insure against this risk with money and nominal government bonds, but all trades must be monetary. We demonstrate that a deflationary policy à la Friedman cannot sustain the constrained-efficient allocation as no-arbitrage imposes too stringent a bound on the return money can pay. The constrained-efficient allocation can be sustained when bonds have positive yields and, under certain conditions, only if they are illiquid. Illiquidity, meaning that bonds cannot be transformed into consumption as easily as cash, is necessary to eliminate arbitrage opportunities due to disparities in shadow interest rates.     

ON THE LONG-TERM EFFECTS OF FISCAL POLICY IN THE UNITED KINGDOM: THE CASE FOR A GOLDEN RULE

This paper uses the SVAR methodology to investigate the effects of public investment on GDP and, more specifically, the effects of the introduction of a golden rule of public finance. We extend the existing literature by estimating a model for the British economy that takes into account long-run factors such as public debt accumulation and policy interactions. We find that in such a long-run framework, public investment has a significant and permanently positive effect on GDP; this result runs counter to the most recent literature on the topic using SVAR, which was limited to a short-run specification. We further find, by comparing different subsamples, that the introduction of the golden rule in 1997 strengthened the positive effect of public investment.     

BRAZILIAN POVERTY BETWEEN AND WITHIN GROUPS: DECOMPOSITION BY GEOGRAPHICAL, GROUP-SPECIFIC POVERTY LINES

This study investigates Brazilian poverty by exploiting geographical differences in the cost of living. We apply the reformulation of the FGT class of poverty measures proposed by Chiappero and Civardi (2006) . This decomposition aims to compute poverty within groups, using group-specific poverty lines, and poverty between groups by adopting a community-wide poverty line. Our findings suggest that the analysis of poverty between and within groups is more exhaustive than the standard methodology when differentiated poverty lines are exploited.     

Emerging models of public–private interplay for European broadband access: Evidence from the Netherlands and Italy

The paper examines the role and function of public–private interplay in the development of municipal initiatives in the broadband sector. The analysis of initiatives in the Netherlands and Italy shows how the interaction between public and private stakeholders can facilitate local broadband initiatives. This interaction has been vital in aligning the interests of different private and (semi-)public parties, in designing the network and in aggregating sufficient demand for broadband services. The comparative analysis examines the steps involved in these initiatives and the strengths and weaknesses of joint public–private activities. The paper shows that the challenge for cooperating stakeholders has been to foster further investment in the upgrading of the network and in the provision of advanced broadband services.     

Mortality Inequality in the Czech Republic*

We examine the evolution of mortality and mortality inequality among the 77 districts of the Czech Republic ranked by a new poverty index, from 1994 to 2016. The country experienced dramatic improvements in mortality for all age categories and both genders, but with very little variation in inequality. Inequality in mortality has remained substantially stable, increasing only for females aged 20–64.     

A survival analysis of de novo co-operative credit banks

This paper studies the features of de novo Co-operative Credit Banks (CCBs) established in Italy during the 1990s. It shows that de novo CCBs in the start-up period are endowed with a higher default risk than long-run incumbent CCBs. Split-population duration models distiguish the determinants of duration and probability of default. The focus is on those determinants related to market structure. We find that duration is positively related to the market share of large banks. Conversely, duration is higher when there are no incumbent CCBs in the same market. Survival probability is directly related to the local level of GDP.All correspondence to Paolo Emilio Mistrulli.
