Evaluación de la conversión a café orgánico usando la metodología de opciones reales

Since the deregulation of the coffee market in 1989, price crises are proof of the uncertainty and risk around coffee growers’ income, particularly for small producers who, in the case of Mexico, have taken action such as the conversion of their traditional crops into the organic production system which, besides the ecological priority, allows them to get a higher income than from conventional coffee. In this document we model as real investment options (RIO) the possibility of conversion from one system into the other one also including the feasibility of abandoning this strategic decision.     

Neural network volatility forecasts

We analyse whether the use of neural networks can improve ‘traditional’ volatility forecasts from time-series models, as well as implied volatilities obtained from options on futures on the Spanish stock market index, the IBEX-35. One of our main contributions is to explore the predictive ability of neural networks that incorporate both implied volatility information and historical time-series information. Our results show that the general regression neural network forecasts improve the information content of implied volatilities and enhance the predictive ability of the models. Our analysis is also consistent with the results from prior research studies showing that implied volatility is an unbiased forecast of future volatility and that time-series models have lower explanatory power than implied volatility.

On the contribution of eco-innovation features to a circular economy: A microlevel quantitative approach

The circular economy (CE) and eco-innovation (EI) are two concepts deemed instrumental in achieving a sustainable transition. They have been proposed in the academic literature and by practitioners and have acquired very high public policy relevance, being endorsed by policymakers and ultimately leading to regulations supporting them. It has been argued that both concepts are compatible and interrelated and that EI is instrumental in achieving the CE. However, little is known about how different EI features contribute to the CE at the microlevel. This article tries to cover this gap. Its aim is to assess and quantify the causal relationship between different EI features and the CE with the help of a unique dataset of small- and medium-sized firms in Spain and an econometric analysis. Our results show that only systemic EIs contribute to a global CE, whereas other EI types such as component additions or small changes in existing production processes could even be barriers to high levels of circularity. It is found out that technological novelty is not relevant for reaching the CE. The results support the understanding of how EIs enable a transition to the CE. Care should be taken not to promote incremental EIs that do not only achieve low (or no) circularity but that effectively lock-in the economic system in solutions that entail a barrier to the achievement of high-level circularity.     

Family firms’ identity communication and consumers’ product involvement impact on consumer response

The purpose of this study is to determine whether the image transfer theory and the elaboration likelihood model can provide a theoretical framework capable of assessing the influence of consumers’ product involvement and family firms’ identity communication through websites on consumer responses. This research conducted an experiment using an eye‐tracking technique measuring attention to family and nonfamily corporate websites. The procedure involved 120 participants. Consistent with the image transfer theory, family firms’ identity through websites positively impacts attitude toward the website and intention to buy. Additionally, the attitude toward the website affects the relationship between family firms’ identity through websites and the intention to buy. In line with the elaboration likelihood model, consumers’ product involvement negatively impacts the relationship between family firms’ identity through websites and intention to buy.     

‘Ruins of Modernity’: The Critical Implications of Unfinished Public Works in Italy

Since the 1950s, the construction of public works has been a significant element of Italy's focus on modernization. Numerous instances of malpractice have resulted in frequent failures of this form of development, with the result that many projects have remained unfinished for decades. In 2007, a group of artists called Alterazioni Video declared these ‘ruins of modernity’ to be a romanticized architectural style; in doing so, their aim is to imbue the sites with new value and dignity. This article uses the artists’ argument as a point of departure to theorize about unfinished public works within the framework of interdisciplinary literatures on modern ruins. In addition, since modern ruins by definition hold a critical meaning––which the artists deliberately excluded from their narrative––the article takes into account the obscure political and economic circumstances causing this phenomenon. After remarking upon specificities and similarities to unfinished neoliberal topographies generated by the 2008 financial crisis, it is concluded that unfinished public works in Italy represent an interesting case serving to enrich debates on incompletion.     

Regulating the banking industry in transition economies: Exploring interactions between capital and reserve requirements

This paper examines the ‘prudential' role of reserve requirements in transition economies using a general-equilibrium banking model. The analysis stresses the role that reserve requirements may play in enforcing an adequate level of bank capitalization in a context in which it is difficult to assess the true value of bank assets. The paper also explores the interactions that exist between capital and reserve requirements and the effect of these regulations on the financial structure of banks and on the level of credit and interest rates.     

On Firms and the Next Generations: Difficulties and Possibilities for Business Ethics Inquiry

Despite the centrality of the topic for the debate on sustainability, future generations have largely been ignored by business ethics. This neglect is in part due to the enormous philosophical challenges posed by the concepts of future generations and intergenerational duties. This article reviews some of these difficulties and defends that much clarity would be gained from making a distinction between future generations and the next generations. It also argues that the concept of next generations offers a better starting point for business ethics to incorporate the topic in its research agenda. We then suggest four potential pathways to explore this territory. The four approaches build on the notion of organizations as communities with memory and vision, on the narrative shape of organizational life, on the affinity of stakeholders with the next generation, and on systems of indirect reciprocity. These first two approaches are connected to communitarian approaches to business ethics, and the last two engage in a dialog with contractarian views and stakeholder theory. The article ends with some implications for theory and practice.     

Transformations in Spanish trade union membership

Trade union membership in Spain has undergone several transformations during the long employment boom (1994–2007) and the following crisis. New generations of workers with different attitudes towards trade unionism, the incorporation of female workers and immigrants have changed the forms and contents of the workers' organisations in Spain.     

Macroeconomic Policy Making,Exchange Rate Adjustment and Current Account Imbalances in Emerging Markets

Given a series of crisis events after 2007 the discussion about the adjustment channels of current account imbalances has been revived. We examine the role of exchange rates vs macroeconomic policies as determinants of current accounts for a set of 86 mainly emerging market economies between 1990 and 2013 to identify adjustment channels for global imbalances. We find that nominal exchange rates are not the main determinant of current account positions. Instead, depending on the region, monetary and/or fiscal policies are identified as the main driving force of current accounts. For East Asia and the oil exporting countries sterilization policies, i.e. relatively tight monetary policies, are the main determinants. In contrast for many European periphery countries fiscal policy stances are at the core of current account positions. Only for the Latin American countries does the exchange rate play a significant role as determinant of current account positions.
