Learning in a double-phase cobweb model

Decisions in Economics and Finance - In this paper, we study a class of markets, among which we can mention agricultural and energy markets, characterized by seasonality, i.e., in which demand...     

Competition and cooperation in the exploitation of the groundwater resource

We study the exploitation of a common groundwater resource, first as a static and then as a differential game, in order to take into account the strategic and dynamic interactions among the users of the resource. We suppose that firms can form coalitions or can decide not to cooperate. The non-cooperation regime is characterized by pumping that lead to depletion of the aquifer; the cooperation preserves the resource. Open-loop and feedback equilibria have been computed and compared in order to characterize the existence of cooperators and defectors in water resources management.     

Exit from the high street: an exploratory study of sustainable fashion consumption pioneers

In today's fashion system, dominated by business models predicated on continual consumption and globalized production systems that have major environmental and social impacts, the consumption of ‘sustainable fashion’ takes on an almost paradoxical quality. This paper explores this paradox by focusing on a previously under‐researched group of consumers – ‘sustainable fashion consumption pioneers’ who actively engage and shape their own discourse around the notion of sustainable fashion consumption. These pioneers actively create and communicate strategies for sustainable fashion behaviour that can overcome the nebulous and somewhat paradoxical reality that sustainable development in the fashion industry presents. Specifically, we use passive netnography and semi‐structured interviews to illuminate the role of motivational and contextual factors that help shape these consumers' definitions of sustainable fashion including such key behaviours as purchasing fewer garments of higher quality, exiting the retail market, purchasing only second‐hand fashion goods and sewing or upgrading their own clothing. Central to much of these behaviours is the notion that personal style, rather than fashion, can bridge the potential disconnect between sustainability and fashion while also facilitating a sense of well‐being not found in traditional fashion consumption. As such, our research suggests that for these consumers sustainability is as much about reducing measurable environmental or social impacts as it is about incorporating broader concepts through which to achieve goals beyond the pro‐environmental or ethical.     

Consumers and deregulation of the electricity market in Germany

Against the backcloth of EU regulation, this note looks at the “politics of necessity” regarding electricity provision in Germany. Electricity as a case is chosen because its provision has been undergoing a profound process of liberalisation and deregulation, and there is a considerable amount of experience with the chances and pitfalls of liberalisation in this sector. Secondly, electricity is a network industry and a natural monopoly subject to systematic market failure, which calls for regulation. The paper starts out with a closer look at the consumer as an actor in the regulation process, proposing a three-role model of the consumer as a market player, as a citizen, and as a micro-producer in households and networks. In these roles, consumers take on different social and political identities; they are affected differently by (de)regulation of essential services and have different options for reacting to quality and price issues. It then describes the legal state and the development of deregulation in the electricity sector in Germany. Selected empirical data are presented, and consumer policy implications are drawn.     

Do adhocracy and market cultures facilitate firm-wide integrated marketing communication (IMC)?

The conceptualization of integrated marketing communication (IMC) has evolved from the marketing communications-centered approach (in the early 1990s) to a broader, firm-wide organizational perspective. The latter is adopted in this research to define IMC as a multidimensional concept. This study was conducted to develop a measurement instrument to assess IMC and examine the role of organizational culture in IMC implementation. Data were gathered via an online survey conducted among CEOs and other senior managers. The findings provide evidence of the reliability and validity of the proposed IMC scale and demonstrate that the dominance of an adhocracy (vs. market) culture contributes to building a more IMC-friendly organizational environment.     

The response of asset prices to monetary policy shocks: Stronger than thought

Standard macroeconomic theory predicts rapid responses of asset prices to monetary policy shocks. Small‐scale vector autoregressions (VARs), however, often find sluggish and insignificant impact effects. Using the same high‐frequency instrument to identify monetary policy shocks, we show that a large‐scale dynamic factor model finds overall stronger and quicker asset price reactions compared to a benchmark VAR, both on euro area and US data. Our results suggest that incorporating a sufficiently large information set is crucial to estimate monetary policy effects.     

Thoughts,attitudes and profile of Brazilian consumers regarding food irradiation

This study aimed to examine the neophobia, knowledge, thoughts, and opinions related to food irradiation among consumers living in a small city in Brazil through the application of a behavioral and sociodemographic questionnaire. It was found that the 271 respondents had little knowledge about the process of food irradiation and had low intent to purchase irradiated food; several consumers associated irradiated food with radioactivity and cancer. Individuals with better knowledge about irradiation and those who are young, single, did not live with children, and had higher levels of education and higher monthly family incomes were more likely to buy irradiated foods than others. These results describe the profile of potential consumers of irradiated foods and the knowledge, thoughts and opinions of the residents of a small city relative to food irradiation. This data could assist industries that irradiate foods to adopt strategies that ensure greater acceptance of their products.     

Greenwashing Revisited: In Search of a Typology and Accusation‐Based Definition Incorporating Legitimacy Strategies

Is greenwashing a concept describing companies using misleading communication or is it co‐constructed in the eye of the beholder? By discussing the literature, we find that existing definitions of greenwashing overemphasize the strategic intention to mislead and do not incorporate unjust allegations. Then, by combining signaling theory with legitimacy theory, we frame the communication process of the greenwashing accusation and the emergence of a negative narrative caused by the accusation and its effect on legitimacy. Hence, in this paper we argue that greenwashing epistemologically is constituted in the eye of the beholder , depending on an external accusation. Following this view, the greenwashing accusation is understood as a distortion factor altering the signal reliability of green messages. Based on our conceptual analysis, we provide a conceptual framework introducing a new typology of case‐based greenwashing (greenwashing , false greenwashing , potential greenwashing and no greenwashing ) and the effects of these types on corporate legitimacy. Finally, we propose a revised definition of greenwashing as co‐creation of an external accusation toward an organization with regard to presenting a misleading green message.

On the risk premium in Nordic electricity futures prices

This paper examines empirically the relationship between electricity spot and futures prices, by analysing a decade of data for a set of short term-to-maturity futures contracts traded in the Nordic Power Exchange. It is found that, on average, there are significant positive risk premiums in short-term electricity futures prices. The significance and size of the premiums, however, varies seasonally over the year; whereas it is greatest during winter, it is zero in summer. It is also found that time-varying risk premiums are significantly related to unexpectedly low reservoir levels. Furthermore, before the unprecedented supply-shock that hit the market around the end of year 2002, the risk premiums were related to the variance and the skewness of future spot prices.
