Cooperative movement and widespread prosperity across Italian regions

Our goal is to participate in the debate on regional well-being. To this end, we explore the relationship between prosperity and the cooperative movement at the regional level in Italy between 2010 and 2019. We summarize prosperity through an index originally proposed by Amartya Sen and we apply it to classify Italian regions. We then perform panel analyses showing that there is a positive and significant association between such an index and the cooperative presence. We detect that, and explain why, the cooperative movement contributes to the regional prosperity more through its employment than in terms of the added value it generates.     

Supplier selection-order allocation: A two-stage multiple criteria dynamic programming approach

This paper proposes a two-stage multiple criteria dynamic programming approach for two of the most critical tasks in supply chain management, namely, supplier selection and order allocation. In the first stage, to address multiple decision criteria in supplier ranking, the analytic hierarchy process (AHP) is employed. In the second stage, supplier ranks are fed into an order allocation model that aims at maximizing a utility function for the firm as well as minimizing the total supply chain costs, subject to constraints on demand, capacity, and inventory levels. A dynamic programming approach is crafted to solve the proposed bi-objective model.     

Turnaround user acceptance in the context of HR self-service technology adoption: an action research approach

Growing advancement in electronic human resource management (e-HRM) in general, and human resource (HR) self-service technology in particular, has afforded transformational opportunities in changing the design and delivery of HR services. Despite their importance, our understanding of how acceptance of these technologies can be improved remains limited. To address this shortfall, this study utilises the Technology Acceptance Model (TAM) to consider how HR can drive and influence the adoption of HR self-service technology in an organisation. Utilising an action research approach, this study documents and reflects on the experience of a UK building society in introducing a new version of HR self-service technology, and analyses how interventions can be used to reshape users' perceptions. Our findings show how HR can play a more proactive role in shaping and reshaping users' perceptions towards accepting such a technology by better understanding how systematic interventions can be developed, used and evaluated. Our contributions are not only limited to the theorisation of HR self-service technology based on TAM, but also lie in demonstrating how action research, although currently underused, can be a valid and valuable approach for HR research and practice.     

Corporate responsibility and value creation in the port sector

The paper reviews existing literature on corporate responsibility (CR) in the port sector and proposes a conceptual framework that brings together the CR drivers in port environmental strategies. The conceptual framework is derived from the existing literature and is based on institutional theory. The literature review is supported by a discussion on CR strategies in 10 major ports around the world. The paper argues that ports tend to replicate environmental strategies across regions and learn from each other, and that a competitive focus on logistics tends to strengthen the importance of CR and in particular of environmental performance in ports. For some ports CR has become an integral part of their value creation proposition mostly as a result of competitive pressure. Furthermore, the paper advances also a correspondence between the degree of port agility and the CR profile of the port. Managerial and policy implications are also discussed.     

Identification and Estimation of Engel Curves with Endogenous and Unobserved Expenditures

When dealing with the estimation of Engel curves, measurement errors in expenditure data and simultaneity are likely sources of endogeneity. In this paper we study identification of the parameters that characterize an Engel curve in the presence of both. We consider specifications where budget shares are polynomials in the logarithm of total expenditure, which is the case frequently encountered in empirical applications. We propose an estimation procedure which is an extension of that in Lewbel ( 1996 ) and exploits a control function assumption to correct for the endogeneity of the true unobserved total expenditure.

A bargaining model in general equilibrium

The goal of the paper is to present a simple model of rational endogenous household formation in a general equilibrium framework in which Pareto optimality at the economy level is not necessarily obtained. The simplest example of household formation is the case in which pairs of individuals engage themselves in a bargaining process on the division of some wealth: if an agreement on the distribution is (not) reached, we can say that the household is (not) formed. The vast majority of existing bargaining models predicts agreements on an efficient outcome. A seminal paper by Crawford (Econometrica 50:607–637, 1982) describes a very simple game with incomplete information in which, even with rational agents, disagreement causes welfare losses. We embed that model in a general equilibrium framework and present some results on equilibria both in the bargaining game and the associated exchange economy. Crawford’s results support Schelling’s intuition on the reasons of disagreement: it may arise if players’ commitments are reversible. Crawford shows that high probabilities of reversibility tend to favor the bargaining impasse, in fact with low probability. We prove that even if those probabilities are arbitrarily close to zero, disagreement is an equilibrium outcome, with high probability. That conclusion seems to be an even stronger support to Schelling’s original viewpoint. In the exchange economy model with that noncooperative bargaining game as a first stage, we present significant examples of economies for which equilibria exist. Because of disagreement, Pareto suboptimal exchange economy equilibria exist for all elements in the utility function and endowment spaces and they may coexist with Pareto optimal equilibria even at the same competitive prices.     

Is Ecolabelling a Reliable Environmental Policy Measure?

The rationale of ecolabelling is to enable firms to reap the willingness-to-payfor the environmental attributes of goods by helping consumers toidentify ``green' products. By so doing, ecolabelling is expected tostimulate spontaneous environmental innovation and to reduce aggregatedpollution. Our analysis however outlines situations under whichecolabelling could induce perverse effects, namely increased investment inconventional technologies before the labels are awarded, and examineswhether restricting the issue of labels could constitute an antidote.     

The economics of research,consulting, and teaching quality: theory and evidence from a technical university

We investigate the effect of both research and consulting on teaching quality in higher education, at the individual level. We propose a theoretical model in which academics allocate effort between the three activities, over a two period time horizon, under the assumption of positive spillovers from research to both consulting opportunities and teaching, and of life-cycle effects on incentives. Propositions from the model are tested against data from a mid-sized Italian engineering faculty. We find that teaching quality is negatively related to consulting and positively related to research experience. However, both relationships are not linear, due to the importance of several mediating factors, such as seniority and the role of scientific publications as a signal for attracting consulting opportunities.     

Endogenous time-varying risk aversion and asset returns

Stylized facts about statistical properties for short horizon returns in financial markets have been identified in the literature, but a satisfactory understanding for their manifestation is yet to be achieved. In this work, we show that a simple asset pricing model with representative agent is able to generate time series of returns that replicate such stylized facts if the risk aversion coefficient is allowed to change endogenously over time in response to unexpected excess returns under evolutionary forces. The same model, under constant risk aversion, would instead generate returns that are essentially Gaussian. We conclude that an endogenous time-varying risk aversion represents a very parsimonious way to make the model match real data on key statistical properties, and therefore deserves careful consideration from economists and practitioners alike.
