Pay-as-you-go Social Security and the Distribution of Altruistic Transfers

This paper studies the impact of an unfunded social security system on the distribution of altruistic transfers in a framework where savings are due to both life cycle and random altruistic motivations. We show that the effect of social security on the distribution of these transfers depends crucially on the strength of the bequest motive in explaining savings behaviour. We measure this strength by the expected weight that individuals attach to the utility of future generations. On the one hand, if the bequest motive is strong, then an increase in the social security tax raises the bequests left by altruistic parents. On the other hand, when the importance of altruism in motivating savings is sufficiently low, the increase in the social security tax could result in a reduction of the bequests left by altruistic parents under some conditions on the attitude of individuals toward risk and on the relative returns associated with private saving and social security. Some implications concerning the transitional effects of introducing an unfunded social security scheme are also discussed.     

Efficient and stable collective choices under gregarious preferences

We consider collective choice problems where a set of agents have to choose an alternative from a finite set and agents may or may not become users of the chosen alternative. An allocation is a pair given by the chosen alternative and the set of its users. Agents have gregarious preferences over allocations: given an allocation, they prefer that the set of users becomes larger. We require that the final allocation be efficient and stable (no agent can be forced to be a user and no agent who wants to be a user can be excluded). We propose a two-stage sequential mechanism whose unique subgame perfect equilibrium outcome is an efficient and stable allocation which also satisfies a maximal participation property.     

Not just like starting over - Leadership and revivification of cooperation in groups

We conduct a laboratory experiment to study how, after a history of decay, cooperation in a repeated voluntary contribution game can be revived in an enduring way. Simply starting the repeated game over—a simple fresh start—leads to an initial increase of cooperation, but to a subsequent new decay. Motivated by cooperation decay in organizations we study the potential of three interventions of triggering higher and sustained cooperation, which take place at the same time as a restart. Surprisingly, we find that the detailed explanation of the causes of the decay in cooperation of Fischbacher and Gächter (Am Econ Rev 100:541–556, 2010) combined with an advice on how to prevent decay do not have an effect beyond that of just starting over. In contrast, a one-way free form communication message sent by the leader to the followers strongly revives cooperation. We find evidence that repeated free form communication by the leader further strengthens the reviving effect on cooperation. Combining the two previous interventions does not outperform the pure effect of communication. Our content analysis reveals that leader communication is more people oriented than the expert advice.     

Impact of sustainable management policies on tourism companies' performance: the case of the metropolitan region of Madrid

The adoption of sustainable management practices is booming among service companies, whether due to pressure exerted by external agents or the internal perception that not being aligned with sustainability distances companies from clients and puts companies' long-term prospects at risk. However, few studies have examined the combined effect of implementing environmental management practices and corporate social responsibility practices in the tourism sector. By analysing two surveys conducted with the managers of 370 hotels and 176 restaurants and using structural equations, this study concludes that sustainability practices have a direct and significant impact on the company's competitiveness and on the companies' financial results. However, a separate study of the two surveys shows significant differences between the two analysed groups. This article suggests that despite operating in the same sector, hotels and restaurants behave differently regarding sustainability practices, and they achieve significantly different results in their implementation. In addition, by focusing on the tourism industry, a highly competitive sector, this analysis sheds light on whether investing in sustainability is a good strategy for companies to differentiate themselves and survive in complex sectors.     

When Should Leaders Share Information with Their Subordinates?

We show that when leaders share some of their information with subordinates, decision making is subject to a motivational bias; leaders make the decisions their subordinates want to see. As this bias increases with the quality of the shared information, an improvement of an organization's information might even decrease its efficiency. As a consequence, information sharing is not always optimal. We show however that self-confidence can help the leader to overcome his motivational bias, thus making information sharing more attractive. Conversely, we find that information sharing can help to curb the autocratic tendencies of a self-confident leadership. We conclude that a policy of information sharing and the appointment of a self-confident leadership are most effective when they go hand in hand.     

Using panel data dea to measure CEOs' focus of attention: An application to the study of cognitive group membership and performance

In this study, we examine the existence and performance of cognitive groups. In accordance with the attention‐based view of managerial cognition, cognitive groups are defined as groups of firms in which the CEOs focus their attention on similar strategic elements when seeking to maximize their firm's competitive advantage. We developed a panel data extension of the original Data Envelopment Analysis to gauge CEOs' focus of attention and then clustered firms into groups. We compared our approach with other approaches that use content analysis of CEOs' letters to shareholders and CEOs' demographic characteristics to measure CEOs' attention. Although the different approaches are related, indicating the existence of a common underlying construct (i.e., mental models), our approach explains a higher proportion of the variation in organizational performance.

Income growth and atmospheric pollution in Spain: An input-output approach

The relationships between economic growth and environmental pressures are complex. Since the early nineties, the debate on these relationships has been strongly influenced by the Environmental Kuznets Curve hypothesis, which states that during the first stage of economic development environmental pressures increase as per capita income increases, but once a critical turning point has been reached these pressures diminish as income levels continue to increase. However, to date such a delinking between economic growth and emission levels has not happened for most atmospheric pollutants in Spain. The aim of this paper is to analyse the relationship between income growth and nine atmospheric pollutants in Spain. In order to obtain empirical outcomes for this analysis, we adopt an input-output approach and use NAMEA data for the nine pollutants. First, we undertake a structural decomposition analysis for the period 1995-2000 to estimate the contribution of various factors to changes in the levels of atmospheric emissions. And second, we estimate the emissions associated with the consumption patterns of different groups of households classified according to their level of expenditure.
