The practice of sport and its influence on social values and behaviour education

‘Non-health effects’ of sports practice, as life satisfaction or non-cognitive education, are being adopted as aim in academic journals in several fields. This paper tries to contribute to this literature by focusing on the links between youth sports and the formation of values and social skills. To do this, we have made a survey, in which more than 5000 Spanish students were involved. They were asked about their sport activity, leisure preferences and socio-economic and family characteristics. We analyse separately athletes and non-athletes using Heckman’s two-step method. Therefore, we split the sample based on the likelihood of practising sports initially predicted by a probit analysis. Then, we separately estimate the non-cognitive educational outcomes of each group of individuals. The results of the first step show significant differences in gender, socio-economic and academic performance. In the second step, segregating the sample provides a number of highly significant effects: The cases of household income and videogames frequency play, among others. So, we have detected a different effect of increasing family income on the educational results (positive in the athlete and negative in the non-athlete group). In addition, a more substantial negative effect was observed in time devoted to videogames in the sample of athletes. These results can be used to implement educational policy measures, such as the promotion of sport in schools, or implementing awareness campaigns about responsible engagement in leisure time activities.     

Anti-Discrimination Laws: Undermining Our Rights

The purpose of this article is to argue in favor of a private employer??s right to discriminate amongst job applicants on any basis he chooses, and this certainly includes unlawful characteristics such as race, sex, national origin, sexual preference, religion, etc. John Locke and many after him have argued that people have natural rights to life, liberty, and property or the pursuit of happiness. In this view, law should be confined to protecting these rights and be limited to prohibiting other people from transgressing those rights. The law should not hinder an employer??s ability to discriminate, any more than it should compel people to marry against their wishes. These laws generally emerge from a moral perspective that people think should be imposed on everyone else. But those who don??t welcome those morals are in effect being coerced to abide by them against their will; this is unethical. Finally, it will be argued that the free market has mechanisms by which discrimination will, be rendered powerless to harm its victims.     

A Theory of Socio‐spatial Integration: Problems,Policies and Concepts from a US Perspective

Discussions about socio‐spatial integration in the US have been primarily focused on research into residential segregation. The treatment of these two concepts as opposites has had two consequences. First, most policies for integration have been based solely on concepts of segregation. Second, the intensive criticism directed at integration flows more from those policies than from its conceptual meaning. This article develops a framework for socio‐spatial integration. It does this first by outlining an understanding of segregation and the complexities of its treatment, then by making a distinction between policy applications and the conceptual meaning of integration. This review shows that, rather than suiting a linear approach, socio‐spatial integration can be expressed as a multidimensional relationship that may work independently and at different scales. Socio‐spatial integration is then exposed as the opposite of social exclusion, of which physical proximity between different social groups is just one dimension. Two lines of research are proposed: first, a repositioning of integration as a progressive aspiration and a critique of naturalist conceptions; second, a balancing of the weight of spatial proximity among the different dimensions of integration.     

Going multinational under exchange rate uncertainty

We analyze a model where an exporting firm competes a la Cournot in a foreign market. The firm faces exchange rate uncertainty and has the option to invest abroad. The paper contributes four results. First, real option pricing techniques are used to derive the optimal timing rule of the investment and the price of the firm and foreign competitors. Second, the sunk cost of entry into the foreign market introduces hysteresis in direct investment flows. We find that the degree of hysteresis grows with the number of firms in the industry. Third, we determine the conditions under which dumping may appear and the role of FDI in precluding this type of dumping. Fourth, tariffs have the well known FDI-inducing effect, more so in less competitive markets, and are more effective at deterring delocation. Furthermore, a tariff might have the effect of triggering dumping.     

Services for the underserved: unintended well-being

There is a lack of research on service consumption practices of Base of the Pyramid consumers. This study contributes to the Transformative Service Research agenda by understanding stigmatized service consumption practices and their effect on the well-being of these consumers; this has not been fully addressed until now. Additionally, it is shown that understanding the relations among consumers, communities, and informal service offerings results in the design of services with unintentional positive effects on well-being at individual, collective, and relational levels. Findings show that informal service offerings are non-discriminatory, hassle-free, jargon-free, and reputation-based. These findings pave the way to further explore such complex contexts to better understand the impact of service design on the well-being of such consumers. Positive practices can be adopted by any service industry that intends to serve that segment through the intentional redesign of offerings that are engaging, inclusive, and simple and acknowledge social standing.     

Valuation of VIX derivatives

We conduct an extensive empirical analysis of VIX derivative valuation models before, during, and after the 2008–2009 financial crisis. Since the restrictive mean-reversion and heteroskedasticity features of existing models yield large distortions during the crisis, we propose generalisations with a time-varying central tendency, jumps, and stochastic volatility, analyse their pricing performance, and implications for term structures of VIX futures and volatility “skews.” We find that a process for the log of the observed VIX combining central tendency and stochastic volatility reliably prices VIX derivatives. We also uncover a significant risk premium that shifts the long-run volatility level.     

Modelling the distribution of credit losses with observable and latent factors

This paper proposes a dynamic model to estimate the credit loss distribution of the aggregate portfolio of loans granted in a banking system. We consider a sectoral approach distinguishing between corporates and households. The evolution of their default frequencies and the size of the loans portfolio are expressed as functions of macroeconomic conditions as well as unobservable credit risk factors, which capture contagion effects between sectors. In addition, we model the distributions of the Exposures at Default and the Losses Given Default. We apply our framework to the Spanish banking system, where we find that sectoral default frequencies are not only affected by economic cycles but also by a persistent latent factor. Finally, we identify the riskier sectors, perform stress tests and compare the relative risk of small and large institutions.     

Corruption and total factor productivity: level or growth effects?

This paper adopts a productivity-based perspective in order to study how corruption conditions the efficiency levels of the economies and their TFP growth rate. It attempts to identify the channels through which corruption can influence productivity growth, whether by conditioning improvements in relative efficiency levels or by shifting the production frontier. The results point out that corruption negatively affects both the levels of efficiency at which the economies perform and the growth rate of TFP, suggesting that the negative impact of corruption on technological progress manifest through its influence on human capital.     

The effect of output specification on the optimal policy design for electric utilities

We show that the manner in which the production process is seen when analyzing data on electricity production has an impact on the policy conclusions. In particular, we show that the different specifications of output found in the literature can generate quite diverse views regarding regulation and optimal industry structure, even when using the same data to estimate a cost function. To illustrate this we use information gathered from the Spanish Electric Industry and analyze electricity activities following three approaches: the traditional aggregate activity view, the multistage model and the multioutput-multistage approach. We estimate the degree of economies of scale S and derive marginal costs for all models, plus economies of vertical integration (EVI) for the last two ones. Then we compare these results and verify that the aggregate analysis can mislead policymaking.
