Is There an Optimal Constitution?

The optimal constitution is one that protects people from politicians' thirst of power and preserves citizens' civic virtues. This paper presents a model that blends David Hume's (1741) consideration that in politics every man ought to be supposed a knave, with John Stuart Mill's (1861) conception of self-interested politicians. The optimal constitution is proved to be feasible. However, there are two possible equilibria, the Frey and Brennan-Buchanan equilibrium. It is shown that Bruno Frey's (1997) crowding-in and crowding-out analysis is a particular case of our model. In the Brennan-Buchanan equilibrium there is a long-run neutrality of enforcement on citizens' performance. In general, a trade-off is expected between the optimal number of laws and enforcement. The comparison between the equilibria shows that the Frey equilibrium is the best option to enhance the civic virtues of citizens, while the Brennan-Buchanan equilibrium is the best way to deter the ambitions of self-interested politicians.

The use of Fx derivatives and the cost of capital: Evidence of Brazilian companies

Large corporations have been using derivative instruments as a tool to protect their indirect exposure, as FX risks. A sample with 47 non-financial Bovespa Listed Brazilian companies from 2004 and 2010 was used to test the hypothesis that use of derivatives as a risk management policy tool reduces companies' cost of capital. In contrast to other countries, results rejected this hypothesis, showing that in Brazil there is a positive relationship between using these tools and cost of capital. However, a more in-depth analysis based on the TACC model for a Brazilian company, this hypothesis was not rejected after the 2008 crisis.     

Animal foods and climate change: shadowing eating practices

Animal farming exceeds all forms of transport in terms of global greenhouse gas (GHG) emissions. Despite the implications of the seriousness of addressing animal farming in relation to mitigating the effects of GHG emissions, to date, the relationship between consumer behaviour and climate change has tended to neglect the role of animal foods. This paper reports on a pilot study in which six UK households were ‘shadowed’ to facilitate the investigation of the relationship between animal food practices and environmental practices, as they emerge in day‐to‐day life. Results indicate that most participants make no connection between the two issues at present, in terms of awareness or practice. However, animal foods do have an ambiguous and complex status in most participants' food practices; for instance, being viewed as problematic for reasons of health or animal welfare. This finding suggests that further research is needed into the potential for raising awareness of the link between animal‐based foods and climate change. This might have a role to play in shifting food practices towards more plant‐based, less GHG intensive, foods.     

Competitiveness, resources, and capabilities: empirical evidence from retail banking

This research aims to identify and measure bank employee perceptions of the determinants of competitiveness in terms of resources, skills, and capabilities within the retail banking sector. All the 40 branches of a leading Portuguese bank—the Caixa Geral de Depósitos—operating in two Portuguese districts were surveyed. Our results show that bank competitiveness differs according to performance evaluation, human resource (HR) planning, the system of incentives, and managerial motivation. They also demonstrate that human capital is a source of success in the business of banks, which relies heavily on stable and enduring relationships with customers. The study also provides recommendations for retail bank managers seeking to refine their HR strategies as a means of improving their competitiveness.     

Globalization,Skill Accumulation and the Skill Premium

We analyze the impact of globalization upon the skill premium (inequality) in advanced countries from a two‐goods North–South model with skill accumulation. Globalization consists of an increase in the size of the South. Its impact on inequality depends on its intensity and on the pre‐globalization proportion of skilled workers. The post‐globalization inequality is a non‐monotonic function of the pre‐globalization proportion of skilled workers and of the globalization intensity. The impact is different for the generation in work and for the following generations. There is a threshold value of the skill endowment under (above) which inequality is lower (higher) after than before globalization.     

Spatial Evolution of Social Norms in a Common-Pool Resource Game

We study the conditions for the emergence of cooperation in a spatial common-pool resource (CPR) game. We consider three types of agents: cooperators, defectors and enforcers. The role of enforcers is to punish defectors for overharvesting the resource. Agents are located on a circle and they only observe the actions of their two nearest neighbors. Their payoffs are determined by both local and global interactions and they modify their actions by imitating the strategy in their neighborhood with the highest average payoffs on average. Using theoretical and numerical analysis, we find a large diversity of equilibria to be the outcome of the game. In particular, we find conditions for the occurrence of equilibria in which the three strategies coexist. We also derive the stability of these equilibria. Finally, we show that introducing resource dynamics in the system favors the occurrence of cooperative equilibria.      

Investment, credit, and endogenous cycles

This paper presents a general-equilibrium dynamic Ramsey-type model that can generate endogenous cycle. We assume two different representative agents, borrowers and lenders, and financial intermediaries with inside and outside money. We investigate under which conditions this model presents a cyclical relationship between capital and loans. The sources of endogenous fluctuations in this model come from a credit restriction in the representative-borrower problem.
