Asymptotically Optimal Response‐Adaptive Designs for Allocating the Best Treatment: An Overview

Response‐adaptive designs are being used increasingly in applications, and this is especially so in early phase clinical trials. This paper reviews a particular class of response‐adaptive designs that have the property of picking the superior treatment with probability tending to one. This is a desirable property from an ethical point of view in clinical trials. The model underlying such designs is a randomly reinforced urn. This paper provides an overview of results for these designs, starting from the early paper of Durham and Yu (1990) until the recent work by Flournoy, May, Moler and Plo (2010).     

Bringing Back the Essence of the “S” and “R” to CSR: Understanding the Limitations of the Merchant Trade and the White Man’s Burden

One of the fundamental struggles in corporate social responsibility (CSR) is the uncertainty and inherent contradictions that stem from a company being an individual legal entity and a community of persons. The authors contend that CSR has departed from the essence of “social responsibility.” The paper is a commentary on CSR, presented as two frameworks rooted in individualism—The Merchant Trade (the strategic view of CSR) and The White Man’s Burden (self-righteous CSR heroism that assumes the shackles of responsibility normally offered by others). Both, however, contradict the essence of “social responsibility” pitting individual against community, business against society, and economic needs and realities versus ethical reflection. The authors present a model that advocates a more moderate and realistic approach to CSR that goes back to the essence of social responsibility.     

The EU policy for a plastic economy: Reflections on a sectoral implementation strategy

After reviewing the main EU policy documents on the plastic waste issue, this work conceptualises an analysis framework to investigate farmers' attitudes to market‐based tools (i.e., subsidies, tax‐credits, and payback mechanisms in extended producer responsibility schemes) through which the introduction of an operational scheme for a better management of their plastic waste can be incentivised in line with the 2018 European Strategy for Plastics in a Circular Economy. A total number of 1,783 farmers responded to a purpose‐built questionnaire. Results show that most of the plastic waste they produce is piping and packaging and that tax credit represents their most favoured incentivising tool.     

Why Do We Buy Traditional Foods?

Consumer behavior toward traditional specialties varies according to the cultural context of consumption. It thus becomes crucial to develop marketing strategies that target segments with different levels of familiarity with food. Our article purposes to analyze the purchase drivers of traditional foods known to consumers because of their reiterated consumption. The importance of the product’s attributes, the purchasing motivations, and the information channels are studied by applying the CUB model, which utilizes a probabilistic structure that simulates the individual’s psychological mechanism in adopting a choice of preference. The case study is that of extra-virgin olive oil in Italy, where this product is a fundamental element of the culinary tradition. The results show that in the ambit of traditional specialties, in contexts of elevated familiarity, the traditional information channels of marketing are less effective and call for strategies based on a more direct connection between consumer and producer.     

Relationship lending and firm innovativeness

This study investigates the effects of close ties between firms and banks – as measured by the share and length of the relationship with the main bank, and by the number of lenders – on a firm's ability to develop innovation and introduce new products. As these effects may vary depending on both the type of firm and innovation, this study provides results for small and high-tech firms and distinguishes between process and product innovation. The results suggest that for small firms banks do not intervene at the development stage of an innovation but rather play their traditional role of financing investments for constrained firms. In contrast, relationship banks do play an important role for high-tech firms in the development of a process innovation and in the introduction of new products. In addition, for both types of firms, the financing decision of the main bank seems to be correlated with the lending behaviour of other banks, with multiple borrowing exerting a positive effect on firm innovative capability.     

Childhood and capability deprivation in Italy: a multidimensional and fuzzy set approach

In the last decades, starting with the United Nations Convention on the Rights of the Children in 1989, children’s quality of life have received a growing attention in scientific research, as well as in politics. This work aims to gain insights into Italian children’s living conditions and deprivation of capabilities using the Capability Approach, an alternative normative framework for the evaluation of human development, well-being and freedom by thinking in terms of human functionings and capabilities. From a methodological point of view we present an approach based on a fuzzy methodology applied to data from the EU-SILC 2009 ad-hoc module on children. The use of this methodology makes it possible to preserve the richness of the data available from the EU-SILC survey, that include both monetary and non monetary aspects of children deprivation. To get more insides into Italian children living conditions we also combine the fuzzy methodology with the capability approach at a disaggregated level of analysis by three social economic factors (single parent household, household educational level, macro-region of residence). Besides the well-known Italian North/South disparity of financial indicators—confirmed also for households with children—our findings suggest a new duality for Italian children quality of life, given by the multidimensional domains of deprivation internal or external to children’s households.     

Tax competition and fiscal equalization under corporate income taxation

This paper challenges the view that tax base equalization by the so-called representative tax system (RTS) removes inefficient undertaxation in corporate tax competition. The innovation of the paper is that it focuses on a tax on corporate income, instead of the unit tax on capital considered in previous studies. We employ a tax competition model with fiscal equalization and show that the RTS fails to fully internalize pecuniary and fiscal externalities. As a consequence, the RTS yields inefficiently low tax rates in the Nash equilibrium of the tax competition game between governments. Tax revenue equalization performs even worse, but combined with equalization of private income it implements the efficient tax rates on corporate income.     

Exploring the link between innovation and growth in Chilean firms

We investigate the relation between the introduction of innovation and subsequent firm growth employing a dataset representative of the Chilean productive structure. By means of quantile treatment effects (QTE), we estimate the effect of the introduction of innovation by comparing firms with a similar propensity to innovate for different quantiles of the firm growth distribution. Our results indicate that process innovation positively affects sales growth for those firms located at the 75th and 90th percentiles. Contrarily, product innovation appears not to be a driver of firm performance. We also find that process innovation benefits mature firms at higher quantiles while it positively affects young firms located at low-medium quantiles.     

A comment on “School choice: An experimental study” [J. Econ. Theory 127 (1) (2006) 202-231]

We show that one of the main results in Chen and Sönmez (2006, 2008) [6] and [7] does no longer hold when the number of recombinations is sufficiently increased to obtain reliable conclusions. No school choice mechanism is significantly superior in terms of efficiency.
