FAVOURING FRIENDS

This paper focuses on the friendship effect on donations in a dictator game. Our results indicate that the taste for altruism is substantially increased when friends play the role of recipients. Controlling for reciprocity there is still a significant friendship effect on donations.     

Drivers and barriers of eco‐innovation types for sustainable transitions: A quantitative perspective

Firms are influenced by internal factors (resources and capabilities) and external factors (e.g., regulation) when taking the decision to eco‐innovate. However, the analysis of the internal factors has received much less attention than the external ones. This paper aims to fill this gap in the literature by analyzing the role of resources, competences, and dynamic capabilities (RCCs) as determinants (drivers and barriers) of different eco‐innovation (EI) types. Those EI types contribute differently to the sustainable transition of the economy and society, that is, towards the circular economy. The statistical analyses reveal that RCCs are quite relevant as determinants of EIs, and that different RCCs are more or less relevant for different EI types. In particular, the determinants of systemic and radical EIs substantially differ from those for continuous improvements. Our results suggest that physical RCCs, involvement in green supply chains, an EI‐friendly corporate culture, technology‐push and market‐pull, and internal financing resources represent drivers to these EIs, whereas cooperation, organizational learning, an ISO (International Organization for Standardization) ecological certification, and technological path dependency are barriers. The results may guide firms to pursue competitive and sustainable advantage by innovating through certain EI types corresponding to available and dedicated RCCs. They may also be useful to policy makers who are willing to promote specific EI types.     

Monetary policy,inequality and political instability

Voters in the industrialised countries are increasingly expressing dissatisfaction by dissenting from the established political parties and candidates. Based on the concepts of justice by Hayek, Rawls and Buchanan, we argue that the growing dissatisfaction is rooted in the asymmetric pattern of monetary policies since the mid‐1980s for two reasons. First, the structurally declining interest rates and the unconventional monetary policy measures have granted privileges to specific groups. Second, the increasingly expansionary monetary policies have negative growth effects, which have reduced the scope for compensation of the ones excluded from the privileges. As a result, the acceptance of the prevailing economic and political order is undermined and political instability increases.     

Integrating Servant Leadership into Managerial Strategy to Build Group Social Capital: The Mediating Role of Group Citizenship Behavior

Recently, various studies have suggested that ethical leadership offers an important antecedent of fluid internal workplace relationships, which are conducive of internal social capital. Yet existing research has neither inquired into potential mediators of this relationship nor addressed the role of other distinct leadership strategies in encouraging such a valuable capital. This study advances previous research by examining if servant leadership, which seeks to put followers’ interests and needs first, can account for social capital variance within the work group, which is the building block of organizations. New to the literature, we also investigate whether group citizenship behavior mediates this relationship. A sample of 352 work groups, spanning 187 hotels located in Spain, reveal that group citizenship behavior partially mediates the positive influence of servant leadership on group social capital. Managers can use these findings to lead their businesses in a more socially friendly direction while also building group social capital, which can improve the competitiveness of their work groups, and the entire business.     

GAME THEORY AND PORT ECONOMICS: A SURVEY OF RECENT RESEARCH

The last decade has seen a significant upsurge of studies seeking to examine the impacts of port agents’ strategic decisions. The outcome has been a wide range of results and conclusions. The aim of this work is to provide a review of this recent research in the port industry that uses strategic interaction approaches from industrial organization and game theory. The paper concentrates on five topics: ownership, relationship between ports and their hinterlands, port authorities and port operators’ relations, capacity investment decisions, and port specialization. We present the objectives, methodologies and results of the papers reviewed, with special emphasis on how models are developed. The results are not always consistent between the works analyzed. On the one hand, this could be due to the complexity of the port industry and the high number of agents that intervene. Researchers need to simplify reality to build their models by imposing restrictive assumptions. On the other hand, results could be very sensitive to the techniques used or to the differences on the port environment of the countries of study. However, some conclusions can be extracted and they present a good starting point to develop more sophisticated models. Finally, we also propose avenues for future research.     

Vertical and Horizontal Scope Economies in the Regulated U.S. Electric Power Industry

This paper investigates vertical economies between generation and distribution of electric power, and horizontal economies between different types of power generation in the U.S. electric utility industry. Our quadratic cost function model includes three generation output measures (hydro, nuclear and fossil fuels), which allows us to analyze the effect that generation mix has on vertical economies. Our results provide (sample mean) estimates of vertical economies of 8.1% and horizontal economies of 5.4%. An extensive sensitivity analysis is used to show how the scope measures vary across alternative model specifications and firm types.     

Equilibrium existence in infinite horizon economies

In sequential economies with finite or infinite-lived real assets in positive net supply, we introduce constraints on the amount of borrowing in terms of the market value of physical endowments. We show that, when utility functions are either unbounded and separable in states of nature or separable in commodities, these borrowing constraints not only preclude Ponzi schemes but also induce endogenous Radner bounds on short-sales. Therefore, we obtain existence of equilibrium. Moreover, equilibrium also exists when both assets are numéraire and utility functions are quasilinear in the commodity used as numéraire.     

Ewom and 2.0 Opinion Leaders in the Food Context: A Study with a Sample of Spanish Food-Related Weblogs

There is no doubt that the arrival of the internet has modified dramatically the way and rhythm of our lives which it reflects directly on our consumption patterns and the way in which individuals interact and search for information. Online platforms, generally known as web 2.0, are usual websites where consumers read reviews from other consumers before making a final decision. In turn, opinion leaders emerge preponderantly within this context exerting an unequal amount of influence on the decision of others. The food sector is not apart from this scenario. This study dives into web 2.0 and ewom with reference to food topics in the Spanish arena. For that purpose, a group of opinion leaders in regard to food aspects is selected. Afterwards, the content of the ewom they emit is determined by means of a cluster analysis. This information is of great importance for businesses and professionals in marketing. Discussion and further lines of research are also included in order to guide interesting future studies.     

The institutional rationale of central banking reconsidered

Based on Goodhart’s (1988) The Evolution of Central Banks, I examine both the theoretical arguments and the historical evidence that could sustain the case for the natural emergence of central banks. I criticize Goodhart’s theoretical claim that central banks evolve naturally, by showing that they are far from being uniquely capable of supplying essential banking services. I review historical evidence showing that Goodhart’s historical generalizations are inconsistent with the developments of the vast majority of central banks. History also shows that crucial banking services have tended to be successfully provided by other means, except when governments prevented their development. Finally, I consider whether central banks, if not essential, are at least preferable to alternative arrangements.     

Strategyand Transaction Costs: The Organizationofdistributioninthecarbonatedsoftdrinkindustry

This paper analyzes the ongoing transformation of the soft drink distribution of Coca-Cola and Pepsi-Cola from systems of independent bottlers to captive bottling subsidiaries, A transaction cost-based theory is developed to explain this restructuring. It is postulated that changes in the external environment and the resulting changes in the strategies of Coca-Cola and Pepsi-Cola raised the costs of transacting between them and their independent bottlers. Two types of empirical tests are presented. One exploits the difference in the distribution of Coca-Cola and Pepsi-Cola in the fountain channel. The other consists of statistical analyses of the competitive effects of the move toward captive distribution. Both types of tests support the basic hypothesis.
