An alternative assessment of global climate policies

This paper analyzes alternative pricing schemes for funding investment in climate policies. This paper proposes a new policy scenario, explicitly disentangling the issue of burden sharing of financing new investments from the issue of taxation energy consumption and therefor emissions. We compare traditional allocation schemes with an optimal Ramsey pricing by applying demand elasticity values, derived from empirical estimations of household behavior for the 106 leading countries in the world, representing around 90% of total world energy consumption and carbon emissions in 2014. We calculate country-specific alternative taxation options: uniform, equitable and Ramsey pricing schemes, applied to households, assessing the related welfare effects. Our results show that the optimal pricing scheme, for a given investment need, can improve world welfare at the expenses of equitable considerations. In addition, the aggregate societal benefit outweighs the losses associated with specific group of countries, paving the way for easier political agreement, using compensation schemes to redistribute the proceeds.

Temporary Workers in Italy: Who Are They and Where They End Up

Abstract. Temporary work has been an important component of employment growth in Italy since the early 1990s. This paper focus upon labour market transitions of temporary workers in order to test whether temporary work enhances the subsequent labour market chances. We use propensity score matching to compare subsequent employment outcomes of people who have recently acquired a temporary job with those of people who remained unemployed. Individuals' hetero geneity explains a good amount of the raw differences in the subsequent labour market status of temporary workers and the comparison group. Yet there appears to be a sizable net gain from experiencing a temporary work. Our benchmark average estimate is a 30 percentage points rise in the ‘satisfactory employment’ chances 1 year after the start of the temporary work experience. The net gains are the largest for females and adult people and the areas with low unemployment; moreover, gains are the largest for the most recent years in our sample and for those people who were (according to the propensity score estimates) either least or most likely to exit from unemployment.     

Homocysteine, menopause and cardiovascular disease

A high plasma concentration of total homocysteine (tHcy) and a deficiency of vitamins related to its metabolism, such as vitamin B12 and folate, have been associated with cardiovascular disease. Postmenopausal women have higher concentrations than age-matched premenopausal women, and plasma concentrations of homocysteine in postmenopausal women taking hormone replacement therapy are significantly lower than they are in those who do not take estrogen supplements. Because of the possible mixed effects of HRT on cardiovascular events, surrogate end-points must be evaluated with caution. While measuring homocysteine levels is relatively simple, evidence from well designed trials is awaited before population screening can be advocated. Also, the benefits of reducing homocysteine levels with folic acid and vitamin B6 and B12 supplements are highly debated.     

Supply chain coordination with information design

We consider the coordination of a supplier–retailer supply chain where, in addition to classical contract considerations, a supplier decides the adoption of an information structure (IS) for the supply chain, with a higher-quality IS allowing the supply chain parties to obtain a more accurate demand forecast. Because a wholesale price contract cannot coordinate the supply chain due to misaligned incentives of supply chain parties, we explore what common coordinating contracts in the classical coordination literature can continue coordinating the supply chain with the IS adoption. Interestingly, our analysis appears to reveal the power of simplicity: some simple classical coordinating contracts (e.g., the buy-back and revenue-sharing contracts), though not designed with the IS consideration, still coordinate the supply chain, whereas other more complicated classical contracts (e.g., the quantity flexibility and sales rebate contracts) fail to do so. We derive a general condition for supply chain coordination and show that any contract with a newsvendor-like transfer payment can coordinate the supply chain.     

Vanishing financial contagion?

While a number of crises in emerging markets generated widespread contagion in financial markets during the 1990s, more recent crises (notably, in Argentina) have been mostly contained within national borders. This has led some observers to wonder whether contagion might have become a feature of the past, with financial markets now better discriminating between emerging countries with good and bad fundamentals. Available data suggest that the main channels that contribute to transmitting financial crises across countries are – if anything – even stronger today than in the 1990s. Moreover, anticipation by international investors may help to explain the near-absence of contagion in the context of the Argentine crisis. This paper argues that a prudent working assumption is that financial contagion has not vanished.     

Examining the Incidence and Clients’ Experiences of Single Session Therapy in Italy: A Feasibility Study

Single session therapy (SST) postulates that one session can be sufficient for a client to take charge of the process and work toward their own solutions. Research has been conducted worldwide corroborating SST assumptions with several mental health conditions, but not in Italy. For the first time in Italy, this paper aims to explore: (1) if the most frequent number of sessions in traditional psychotherapy (not SST) is one (Study 1); and (2) the satisfaction of clients who attend SST services and the number who consider one session sufficient to address their presenting problem (Study 2). In Study 1, the records of 476 voluntary clients referred to three different traditional (not SST) psychological services in the west-central region of Latium, Italy, were retrospectively screened, and the number of sessions attended by each client recorded. In Study 2, 85 consecutive clients who voluntarily asked for SST with seven mental health professionals across Italy received a link to an online ad hoc survey, 1–3 weeks after the consultation, evaluating their experience. Study 1 found that the most frequent number of traditional psychotherapeutic (not intentionally SST) sessions was one (124 out of 476 clients (26%). Study 2 found that 44 out of 85 clients (52%) considered one session to be enough, as they felt better or much better and chose not to attend further sessions. Of those who asked for a second session (41 clients), 33 clients (80.5%) indicated that the first session was not enough and 8 clients (19.5%) wanted to address a new problem. These results converge with previous international studies and provide encouragement for the use of SST in both private and public psychological services to address the demand for timely mental health services in Italy. Further research is needed to support the efficacy of SST and to evaluate its cost-effectiveness.     

Doing Sociology in the Age of ‘Evidence-Based Research’: Scientific Epistemology versus Political Dominance

Social science history from its beginnings has witnessed periods of confrontation between – generally speaking – qualitative and quantitative paradigms, even talking of ‘war’, ‘wrestlers’ and ‘warriors’. And, again from the very beginnings, our discipline has been forced to relate with funding agencies. Sometimes, the two paths – the scientific one and the financial one – cross: we may think at the role of the private foundations in financing a certain type of investigation, notably surveys against case studies or qualitative research. Nowadays, we see an increased attention by federal agencies and private foundations on a particular sector of research, randomized controlled trials (RCTs), focusing on techniques seen intrinsically superior from the methodological and epistemological point of view. This article will analyze the recent increase of the randomized controlled trials as the new “gold standard” for social research; the call for the “experimenting society” (Campbell American Psychologist, 24(4), 409–429, 1969), willing to import the randomized controlled trials approach into the field of social policy and planning, is not new, if we think that yet in 1963 Campbell and Stanley wrote that “a wave of enthusiasm for experimentation dominated the field of education in the Thorndike era, perhaps reaching its apex in the 1920s” (Campbell and Stanley 1963/1966: 2). Many problems of validity with RCTs soon came to be recognized – even by Campbell, who stated that he has “held off advocating an experimenting society until they can be solved” (Campbell Evaluation Practice, 15(3), 291–298, 1994: 294). In the following years a different set of evaluation strategies were developed, but today there’s a new effort to re-introduce the experimental approach in the academic arena. What is the difference? As we will see, the scientifically-based research is now established and codified by law, funding is linked to a particular way of doing research, and the consequences on scientists work are yet to be explored.
