Degrowth,the past,the future,and the human nature

In the last years, different sources point to a same message: industrial civilization has entered an overshoot mode, the natural limits to growth have been already surpassed. This frontier does not wait for us in the future; it already belongs to our past. If population and the economy are truly beyond the limits, then current visions and theories of social change would be deeply perturbed. If the development era is approaching its end, then many sociological theories on current societies will share the same destiny, sustainable development doctrines between them. It is worth to examine theories that explicitly look at the social world this way or that – at least – are not incompatible with it. Differences between these theories depend on sociological, psychological and anthropological questions; or, in other words, they depend on the human nature. Exploring the relationship between degrowth and the human nature gives rise to debates about selective pressures under conditions of scarcity (human evolution), historical and anthropological evidence, philosophy, and sociology (institutional resilience, utopies as whole society experiments…). As its conclusion, the argument accepts that an evolutionary perspective supports that there are some potentials for conscious social change even in a way-down era, but it does not justify the belief in a particular only line of history. This conclusion does not satisfy the desire of knowing the future; nevertheless it may be the only one possible. The future is not written. Neither in history nor in evolution; not even in the mixture of history and evolution that conforms us as inhabitants of the Earth.     

Calculating the Efficient Frontier for the Portuguese Stock Market

The paper investigates the efficient frontier and capital market line for the Portuguese stock market before and after the Global Financial Crisis. The efficient frontier and capital market line shift to positions that offer investors better opportunities as we move from 2000‐2008 to 2009–2015.     

New approaches in transportation planning: happiness and transport economics

The measurement of social and psychological phenomena has been advanced by recent progress in the fields of behavioural economics and hedonic psychology. In addition, the increased interest in understanding how individuals perceive their own quality of life, has led to investigating the relations between various macro and individual level variables, generically subsumed as happiness. For many “happiness is considered to be an ultimate goal in life” and it plays an important role in the way people perceive the overall society they live in. Therefore, social scientists and behavioural economists are now stressing the importance of well-being measures, related to people’s evaluations of their quality of life in addition to economic indicators. In the transport sector, project evaluation is mainly based on cost–benefit analyses using economic indicators. However, any provided transportation project/service impacts the quality of the travel experience, the well-being of travellers and their travel behaviour. Competitiveness of modes may be also affected by the promotion of derived or experienced travellers’ well-being. Thus, existing behavioural travel choice models should be enhanced with regards to their behavioural validity incorporating the impacts of travelling happiness/ satisfaction. This study aims to understand and model the impact of stated (anticipated) happiness in the decision choice between a private transport mode—car, and a public transport mode—metro.     

Overview of the Portuguese Three Pillar Pension System

In order to cope with alleged future financial problems, several changes were made to the design of the Portuguese pension system since 2000. The aim was to achieve the diversification of retirement income sources across providers, both public and private, across the three pillars: public, industry-wide, and personal, and also across the financing forms of pay-as-you-go and funded. This paper describes these changes and analyses the results regarding, principally, the weight of each pillar and the investment performance of both public pension reserves and private pension funds. The main finding is that, in effect, there is one substantial longstanding pillar, and that is the public system.     

Assessing and valuing the nonlinear structure of hedge fund returns

Several studies have put forward that hedge fund returns exhibit a nonlinear relationship with equity market returns, captured either through constructed portfolios of traded options or piece‐wise linear regressions. This paper provides a statistical methodology to unveil such nonlinear features with respect to returns on benchmark risk portfolios. We estimate a portfolio of options that best approximates the returns of a given hedge fund, account for this search in the statistical testing of the nonlinearity, and provide a reliable test for a positive valuation of the fund. We find that not all fund categories exhibit significant nonlinearities, and that only a few strategies provide significant value to investors. Our methodology helps identify individual funds that provide value in an otherwise poorly performing category. Copyright © 2010 John Wiley & Sons, Ltd.     

European Periphery Crises,International Financial Markets,and Democracy

This article analyzes the origin and causes of the recent economic and financial crises, mainly for the countries located in the periphery of the European Union (EU), as well as their evolution and transformation into social, political, and institutional crises. After explaining the differential impact of the crises on EU economies, we analyze how the economic policies developed thus far not only are unable to resolve the current crisis pattern but also actually entail a risk to the present democratic models by transferring the legitimate control over governments from citizens and democratic parliaments to unelected, nonrepresentative international financial markets.     

Success in failure? Reflections on the changing Spanish audit environment

The 1990s in Spain have witnessed a significant shift in attitudes towards the role of auditing, with promises of more transparent reporting being replaced by talk of audit expectations gaps. This paper explores the changing atmosphere, both through an analysis of one of the most notorious scandals of recent times - involving the Banco Español de Credito (‘Banesto’) - and a more general review of the way the Spanish profession has responded to such downturns in public expectations of auditing. While at first sight, the profession appears to have become more defensive and the audit environment more competitive, the multinational accounting firms do appear to have strengthened their position in the Spanish audit market. Intriguingly, despite public expressions of concern with the quality and capabilities of auditing and the imposition of large fines on audit firms for inadequate audit work, proposed ‘solutions’ for improving audit quality include the establishment of a self-regulated audit regime and reductions in auditor liability. The Spanish experience allows for some timely reflections on the significance of an audit expectations gap and highlights the importance of viewing the audit function from an international perspective.     

First-best health policy in vaccine markets with health and network externalities

This paper considers an oligopolistic market for a vaccine, characterized by negative network effects, which stem from the free-riding behavior of individuals engaged in a vaccination game. Vaccine markets often suffer from three imperfections: high concentration, network effects, and a health externality (contagion). The first conclusion of the paper is that the negative network externality is important as a market distortion, as it may lead to significant welfare losses. The second and main part of the paper develops a two-part per-unit subsidy scheme that a social planner could use to target both consumers and producers of vaccines. The scope of such a subsidy scheme to induce the firms to produce the first-best output without network effects (which is the most ambitious first-best target) is investigated. In many cases, while the first-best is attainable, it requires negative prices for vaccines, which amounts to rewarding consumers to induce them to vaccinate.     

Trade liberalization,consumption shifting and pollution: Evidence from Mexico's used vehicle imports

This paper develops a model of used vehicle trade between the United States and Mexico, countries with different environmental regulations regarding vehicle emissions. We demonstrate that the United States, with its strict environmental regulations, has a motive to export used vehicles to Mexico, which impacts air pollution emissions from vehicle driving in Mexico. Using unique data on the import and registration of vehicles in Mexico after NAFTA, we find that Mexico's used vehicle imports reduce pollution emissions generated from vehicle driving mainly because of the technique effect, that is, model–age‐comparable vehicles imported from the United States emit less than those originally operated in Mexico.
