Determinants affecting consumers' attention to fish eco-labels in purchase decisions: a cross-country study

2022

PurposeThe purpose of this study was to investigate the role of consumer altruism and other socio-cultural factors in predicting how much attention consumers pay to seafood eco-labels.Design/methodology/approachThe empirical investigation was carried out by administering an online questionnaire to a sample of Italian and Spanish people from December 2019 to April 2020. After carrying out the principal component analysis procedure, the work made use of an ordinal logistic regression.FindingsBoth Italian and Spanish consumers with an altruistic attitude, who feel that food produced in a sustainable way can protect the environment and workers, appear more likely to take an eco-label into accou…

Ragion pratica e razionalità economica. Oltre la scissione

2020

ll saggio ricostruisce alcuni passaggi storici e teorici circa i rapporti tra la ragion pratica e la razionalità economica. In particolar modo si sofferma sulla riscoperta contemporanea della filosofia pratica, come orizzonte utile per comprendere in chiave etica la dimensione economica. La separazione tra etica ed economia, avvenuta nella tarda modernità (da Mandeville in poi), ha comportato l’accettazione dell’Utilitarismo quale paradigma filosofico e della razionalità scientifico-avalutativa come modello di ricerca. Ciò ha causato una riduzione dell’economia e dei suoi modelli di sviluppo a mere questioni quantitative. La sfera economica invece dovrebbe riguardare l’utile in vista del be…

More firms, more competition? The case of the fourth operator in France's mobile phone market

2010

Accepted, Forthcoming; International audience; To foster competition the French government authorized a fourth operator, ‘Free', to enter the country's mobile phone market at the end of 2009 alongside Orange, SFR and Bouygues Telecom (BT), who held respectively one-half, one-third and one-sixth of the market. By using a stylized model of France's phone market, we have examined what we call the regulator's nightmares and dreams. If Cournot competition is in place before Free's entry, minimizing the total profit fails to maximize the consumer surplus and the total surplus; the maximum most realistic price fall is 6.7% compared to three-way competition and could be 1.7% only; if Orange, SFR an…

Optimal hedging under biased energy futures markets

2020

Abstract Optimal futures hedging positions for those agents trying to maximize their expected utility will depend on their view about the evolution of the market and on how risk adverse they are. The most risk adverse agents will probably decide to full-cover their positions. But when a futures bias exists, hedgers with moderate or low degree of risk aversion can alter their strategy depending on the expected gains in futures markets. In our application to the UK natural gas market, we find a statistically significant time-varying negative futures bias that can be forecasted with confidence. As a result of this bias, most effective and best performing hedging strategies for moderate risk-av…

Portfolio performance evaluation with generalized Sharpe ratios: Beyond the mean and variance

2009

The main purpose of this paper is to present a theoretically sound portfolio performance measure that takes into account higher moments of the distribution of returns. First, we perform a study of the investor's preferences to higher moments of distribution within expected utility theory and discuss the performance measurement. To illustrate the investor's preferences to higher moments and the computation of a performance measure, we provide an approximation analysis of the optimal capital allocation problem and derive a formula for the Sharpe ratio adjusted for skewness of distribution. This performance measure justifies the notion of the Generalized Sharpe Ratio (GSR) introduced by Hodges…

Household debt and labor market fluctuations

2011

Abstract The co-movements of labor productivity with output, total hours, vacancies and unemployment have changed since the mid 1980s. This paper offers an explanation for the sharp break in the fluctuations of labor market variables based on endogenous labor supply decisions following the mortgage market deregulation. We set up a search model with efficient bargaining and financial frictions, in which impatient borrowers can take an amount of credit that cannot exceed a proportion of the expected value of their real estate holdings. When borrowers' equity requirements are low, the impact of a positive technology shock on the marginal utility of consumption is strengthened, which in turn re…

Resumen: Objetivo: Identificar el perfil sociodemográfico del usuario de la homeopatía en España. Diseño: Estudio cuantitativo. Emplazamiento: España. Corpus: Base de datos del Centro de Investigaciones Sociológicas (Estudio 3205, febrero de 2018), con un total de 2.486 entrevistas, y se analiza una submuestra (n = 124), que agrupa a todos los ciudadanos que afirman que han usado la homeopatía en España en los 12 meses anteriores. Mediciones principales: Se utilizaron los porcentajes, las medias y/o la desviación estándar de las medias, así como la significación de los cambios en las distintas variables analizadas entre la población en general y los usuarios específicos de la homeopatía en …

A user-friendly software for sustainable management of urban areas

2002

The need to collect and process information on urban ecosystem requires the introduction of innovative scientific tools, in order to analyze the current urban factors and to optimize the energetic and environmental profile of urban systems, with regard to carrying capacity and territorial needs and vocations. Addressing these needs requires two main elements: (i) public availability of transparent data; and (ii) availability of interactive software designed to make easier exploration of data, models and results. The aim of the present paper is to show a user-friendly software, which is designed as a decision support system for policy makers in the multi-criteria selection among different pl…

Optimization on ports activation towards energy efficient data center networks

2018

Nowadays, Internet of thing including network support (i.e. checking social media, sending emails, video conferencing) requires smart and efficient data centers to support these services. Hence, data centers become more important and must be able to respond to ever changing service requirements and application demands. However, data centers are classified as one of the largest consumers of energy in the world. Existing topologies such as ScalNet improves the data center scalability while leading to enormous amounts of energy consumption. In this paper, we present a new energy efficient algorithm for ScalNet called Green ScalNet. The proposed topology strikes a compromise between maximizing …
