The somatic marker hypothesis: A neural theory of economic decision

Modern economic theory ignores the influence of emotions on decision-making. Emerging neuroscience evidence suggests that sound and rational decision making, in fact, depends on prior accurate emotional processing. The somatic marker hypothesis provides a systems-level neuroanatomical and cognitive framework for decision-making and its influence by emotion. The key idea of this hypothesis is that decision-making is a process that is influenced by marker signals that arise in bioregulatory processes, including those that express themselves in emotions and feelings. This influence can occur at multiple levels of operation, some of which occur consciously, and some of which occur non-consciously. Here we review studies that confirm various predictions from the hypothesis, and propose a neural model for economic decision, in which emotions are a major factor in the interaction between environmental conditions and human decision processes, with these emotional systems providing valuable implicit or explicit knowledge for making fast and advantageous decisions.

Postmodern Values and Leisure in Young Spanish University Students: An Exploratory Study

This article reports exploratory research about tendencies toward postmaterialism in university students. This paper used the theoretical framework proposed by Inglehart regarding three categories of leisure: postmaterialist, materialist and common. Students from a Spanish university (N = 1036) completed questionnaires that evaluated their materialist-postmaterialist values, how often they practiced the activities included in each category of leisure and the motivational factors involved in them. The results revealed that university students showed a tendency toward postmaterialism. Further, relationships were found between materialist-postmaterialist values and categories of leisure. This study results suggested that the tendency toward postmaterialist values may be a factor in structuring the leisure patterns of young Spanish university students.     

Organizational Culture, Individual Differences and the Participation System in Cooperativism of Associated Workers in Andalusia, Spain

From a psychosocial perspective, we have attempted to identify the characteristics of the democratic systems of a sample of 36 Andalusian cooperatives of associated workers. In this study it has become evident that those who participate the least in the governments of their organizations are the workers and those with less education. Thus, there is a high degree of association between participation in the governing of the cooperative and the development within it of an appropriate organizational culture. The results of this study have allowed us to empirically deconstruct the concept of cooperative democracy, and this process may have an effect on the improvement of human resource administration in this type of organization.     

The fragile capital structure of hedge funds and the limits to arbitrage

During a financial crisis, when investors are most in need of liquidity and accurate prices, hedge funds cut their arbitrage positions and hoard cash. The paper explains this phenomenon. We argue that the fragile nature of the capital structure of hedge funds, combined with low market liquidity, creates a risk of coordination in redemptions among hedge fund investors that severely limits hedge funds' arbitrage capabilities. We present a model of hedge funds' optimal asset allocation in the presence of coordination risk among investors. We show that hedge fund managers behave conservatively and even abstain from participating in the market once coordination risk is factored into their investment decisions. The model suggests a new source of limits to arbitrage.     

The impact of multiple structural changes on mortality predictions

Most mortality models proposed in recent literature rely on the standard ARIMA framework (in particular: a random walk with drift) to project mortality rates. As a result the projections are highly sensitive to the calibration period. We therefore analyse the impact of allowing for multiple structural changes on a large collection of mortality models. We find that this may lead to more robust projections for the period effect but that there is only a limited effect on the ranking of the models based on backtesting criteria, since there is often not yet sufficient statistical evidence for structural changes. However, there are cases for which we do find improvements in estimates and we therefore conclude that one should not exclude on beforehand that structural changes may have occurred.     

Effects of hiring former employees of multinationals in the absorptive capacity of local firms

The attraction of foreign direct investment seeks, among other things, to increase the productivity of local companies through knowledge spillovers. However, the empirical evidence in this regard is contradictory. One influential factor is the absorptive capacity of the local companies. This article analyzes the effect of the presence of former employees of multinational corporations as employees of local companies, on the absorptive capacity of said companies. The study was done in Costa Rica, a country known for its successful strategy in the subject matter. The data come from a survey applied to 1167 companies by the Observatorio Costarricense de las Pymes in 2011. It was found that the hiring of former employees of multinational corporations by local companies has a positive effect on the index of absorptive capacity of companies in all productive sectors. Specifically, this hiring of former employees increases the index of absorptive capacity by nine percentage points, with differences by sector and the size of the company.     

Short-term wholesale funding and systemic risk: A global CoVaR approach

We use the CoVaR approach to identify the main factors behind systemic risk in a set of large international banks. We find that short-term wholesale funding is a key determinant in triggering systemic risk episodes. In contrast, we find weaker evidence that either size or leverage contributes to systemic risk within the class of large international banks. We also show that asymmetries based on the sign of bank returns play an important role in capturing the sensitivity of system-wide risk to individual bank returns. Since short-term wholesale funding emerges as the most relevant systemic factor, our results support the Basel Committee’s proposal to introduce a net stable funding ratio, penalizing excessive exposure to liquidity risk.
