PARENTS KNOW THEM BETTER: THE EFFECT OF OPTIONAL EARLY ENTRY ON PUPILS' SCHOOLING ATTAINMENT

The effect of optional early school entry on pupils' educational outcomes is investigated using data covering the entire population of Italian primary school students and exploiting exogenous thresholds imposed by norms regulating first enrollment. Results highlight the fact that pupils whose parents can choose when their children start school perform better than those who are bounded by terms imposed by law. These findings suggest that parental choice leads to a better match between pupils' characteristics and the beginning of formal learning. Results show that giving parents the option to anticipate or delay school entry could be a beneficial measure. (JEL I20, H52)     

Product defects are not created equal: prioritizing production process improvements

Abstract

Despite manufacturers’ efforts to improve quality, customers frequently experience product defects. Based on expectation confirmation theory, hypotheses concerning the effects of experiencing product defects on overall quality perceptions and loyalty to the product manufacturer have been developed and tested. Our results show that experiencing product defects related to performance, ease of use, prestige and versatility damages overall quality perceptions and decrease customer loyalty to the product manufacturer, either fully or partially mediated through overall quality perceptions. Contrary to frequent claims in the literature, experiencing even a single product defect per quality dimension damages customers’ quality perceptions. Furthermore, different types of product defect damage customer perceptions of product quality and loyalty to the manufacturer differently. Building on these results, we develop a defect typology and a portfolio visualization that allows operations managers to prioritize production process improvements.     

Schengen's Soft Underbelly? Irregular Migration and Human Smuggling across Land and Sea Borders to Italy

La migration illégale à destination de l'Italie ou passant par ce pays est généralement associée dans l'esprit des gens à l'image de centaines, voire de milliers de migrants traversant la Méditerranée entassés dans de vieux rafiots se maintenant tout juste à flot. On considère souvent que les traversées de ce type sont la preuve de l'existence de cartels criminels qui seraient structurés hiérarchiquement, centralisés, extrêmement bien organisés et actifs au niveau mondial. Le seul problème avec de telles idées reçues est qu'elles ne concordent absolument pas avec les faits dont on dispose et n'ont pas grand chose à voir avec la réalité concrète des systèmes de migration illégale. Cette étude passe en revue un certain nombre de dossiers de tribunaux italiens concernant diverses organisations qui opèrent aussi bien au travers des frontières terrestres que maritimes. Elle montre comment de telles organisations opèrent en tenant compte de diverses spécificités locales et contraintes structurelles.     

Lottery- and survey-based risk attitudes linked through a multichoice elicitation task

We analyze the results from three different risk attitude elicitation methods. First, the broadly used test by Holt and Laury (2002), HL, second, the lottery-panel task by Sabater-Grande and Georgantzis (2002), SG, and third, responses to a survey question on self-assessment of general attitude towards risk (Dohmen et al. 2011). The first and the second task are implemented with real monetary incentives, while the third concerns all domains in life in general. Like in previous studies, the correlation of decisions across tasks is low and usually statistically non-significant. However, when we consider only subjects whose behavior across the panels of the SG task is compatible with constant relative risk aversion (CRRA), the correlation between HL and self-assessed risk attitude becomes significant. Furthermore, the correlation between HL and SG also increases for CRRA-compatible subjects, although it remains statistically non-significant.     

t-Designs associated with non degenerate conics in a Galois plane of odd order

Some t-designs in a Galois plane of odd order are constructed by means of sets of points lying on a non degenerate conic and on the sides of suitable self-conjugate triangles.     

A new approach to stock price modelling and the efficiency of the Italian stock exchange

In this paper, we propose a new model of asset prices which takes account of the investment strategies of three different kinds of agents: the market-makers, who operate rationally on the basis of the asset fundamentals, the smart buy-and-sell agents, who intervene when the prices reach particular levels and the non-smart buy-and-sell agents, who trade infrequently, mainly following psychological motivations. The different behavior of these groups of agents can determine temporary inefficiences on financial markets and we show that, by considering these inefficiences, it is possible to improve forecasting of asset prices.     

Trade Union Action and Privatisation in Western Europe: Recent Dilemmas*

Abstract. The Author examines the policies of privatisation in Western Europe and the responses made by trade unions. Privatisation seems to induce the trade union movement to shift its emphasis from traditional issues toward new and challenging ones, such as a major co-operation in the management of the privatised companies. Therein, the extension of interest and control by the unions into new areas such as investment, planning, work organisation and design constitute a challenge to trade union core mandate. In some union circles there are fears about unions embracing what appear to be managerial strategies in a period of deep transformation and turbulence. Moreover, according to some union leaders any attempt by the unions to go beyond the “oppositional and defensive role” would result in a confusion and misrepresentation of their members' interests.     

Ergonomics and design for sustainability in healthcare: ambient assisted living and the social-environmental impact of patients lifestyle

This work presents considerations on Ergonomics and Design for Sustainability in the healthcare field based on research experiences of the Technology and Design for Healthcare (TeDH) research group of INDACO (Industrial design, communication, arts and fashion) department of Politecnico di Milano. In order to develop a multidisciplinary approach to design able to answer to specific user needs such as elderly in an environmental sustainable way (1) this paper shows the results we achieved concerning ergonomics and environmental impact in product development (2), the extension of this approach to interior and home design and the advantage of the application of Information Communication Technologies (ICT). ICT can help people with special needs to make their everyday life easier and more safe, at the same time, ICT can make social-environmental impact of everyday behavior evident and can be applied to manage sustainability. The specific theme is thus to integrate ergonomics and sustainability competences in the development of Ambient Assisted Living through a Product- Service System approach. The concept of product service system has the potential to improve product performances and services, establish new relations and networks with different actors in order to satisfy user needs and apply a systems approach considering environmental, social and economic factors in the users' environment.     

Vaginal birth after caesarean: Views of women from countries with low VBAC rates

Problem and background

Vaginal birth after caesarean section is a safe option for the majority of women. Seeking women’s views can be of help in understanding factors of importance for achieving vaginal birth in countries where the vaginal birth rates after caesarean is low.
