Modern energy consumption and economic modernisation in Latin America and the Caribbean between 1890 and 1925

In the absence of comparable macroeconomic indicators for most of the Latin Americaneconomies before the 1930s, the apparent consumption of energy is used in this paper as a proxyof the degree of modernisation of Latin America and the Caribbean. This paper presents anestimate of the apparent consumption per head of modern energies (coal, petroleum andhydroelectricity) for 30 countries of Latin American and the Caribbean for 1890 to 1925,multiplying the number of countries for which energy consumption estimates were previouslyavailable. As a result, the paper provides the basis for a quantitative comparative analysis ofmodernisation performance beyond the few countries for which historical national accounts areavailable in Latin America.

Banks, liquidity crises and economic growth

How do the liquidity functions of banks affect investment and growth at different stages ofeconomic development? How do financial fragility and the costs of banking crises evolve with the level of wealth of countries? We analyze these issues using an overlapping generations growth model where agents, who experience idiosyncratic liquidity shocks, can invest in a liquid storage technology or in a partially illiquid Cobb Douglas technology. By pooling liquidity risk, banks play a growth enhancing role in reducing inefficient liquidation of long term projects, but they may face liquidity crises associated with severe output losses. We show that middle income economies may find optimal to be exposed to liquidity crises, while poor and rich economies have more incentives to develop a fully covered banking system. Therefore, middle income economies could experience banking crises in the process of their development and, as they get richer, they eventually converge to a financially safe long run steady state. Finally, the model replicates the empirical fact of higher costs of banking crises for middle income economies.

Comunidade política, imigração e coesão social: o caso português

This work contributes to an understanding of how the existence of multiple ethnic- cultural belongings in the political community concurs with the maintenance of a socially cohesive and politically united community. Considering the immigration reality in Portugal, we tried to identify the bonds that link immigrants to the political community and how those bonds can be mobilized to integrate immigrants in a common living project inside the national territory. Methodologically, this investigation is based in a qualitative and quantitative analysis of the policies and measures applied in Portugal in the immigration sphere, as well as the results of the empirical work we carried out with two immigration groups (Brazilians and Cape Verdeans) living in Lisbon’s metropolitan area, and the answers to a survey we sent to immigrant associations. The results of this research revealed the existence of a certain political ambivalence concerning the immigrant integration process, which expresses itself to a certain degree in the way national citizens and immigrants appraise the immigrant contribution to Portuguese society. The prevailing and blurred idea states that immigration expenses don’t make up for the benefits, and that is likely to influence the mutual relationship established between the two. Despite the existence of objective situations of social and economic disparity and despite a feeling of discrimination shared between immigrants, it is possible to identify a progressive citizenship universalization and the formal acceptance of immigrant religious and cultural traditions, even though the Portuguese parliament does not reflect such diversity. Thus, we perceive the possibility of warranting specific ethnic and cultural minority rights without the ethnicization or culturalization of political representation, and the general standards that serve as a backbone to the national political community might be enough to warrant that protection. Notwithstanding, some signs suggest that immigrant access to public sphere might not be easy, and this might have repercussions in the visibility and in the public discussion of demands, with outcomes on the type of integration policies Portugal applies.

Local distribution of blackfly (Diptera, Simuliidae) larvae in two adjacent streams: the role of water current velocity in the diversity of blackfly larvae

This study aimed to evaluate the influence of water velocity speed on the local distribution and taxocenosis structure of blackfly larvae. The larvae were collected from two adjacent streams located in the municipality of Angra dos Reis (RJ): Caputera River and one of its tributaries. Riffle litter patches were sampled randomly using a 30 x 30 cm quadrat. Four blackfly species were found: Simulium incrustatum s. l. Lutz, 1910; Simulium (Inaequalium) sp. ; Simulium pertinax s. l. Kollar, 1832 and Simulium subpallidum s. l. Lutz, 1909. Among these species, Simulium pertinax s. l. was clearly associated with higher water current speeds, while Simulium subpallidum s. l. showed association with lower water velocities, and Simulium (Inaequalium) sp. had a relatively constant distribution along the water current gradient.

Economic rationality and ethical behavior

This paper argues that economic rationality and ethical behavior cannotbe reduced one to the other, casting doubts on the validity of formulaslike 'profit is ethical' or 'ethics pays'. In order to express ethicaldilemmas as opposing economic interest with ethical concerns, we proposea model of rational behavior that combines these two irreducible dimensions in an open but not arbitrary manner. Behaviors that are neither ethicalnor profitable are considered irrational (non-arbitrariness). However,behaviors that are profitable but unethical, and behaviors that are ethicalbut not profitable, are all treated as rational (openness). Combiningethical concerns with economic interest, ethical business is in turn anoptimal form of rationality between venality and sacrifice.Because every one prefers to communicate that he acts ethically, ethicalbusiness remains ambiguous until some economic interest is actuallysacrificed. We argue however that ethical business has an interest indemonstrating its consistency between communication and behavior by atransparent attitude. On the other hand, venal behaviors must remainconfidential to hide the corresponding lack of consistency. Thisdiscursive approach based on transparency and confidentiality helpsto further distinguish between ethical and unethical business behaviors.

Estudo das perceções da Comunidade da Palmeira (Ilha do Sal, Cabo Verde) sobre a sustentabilidade das pescas

A pesca teve sempre grande importância socioeconómica para as comunidades costeiras de Cabo Verde, oferecendo meios de subsistência e, devido à vocação marítima do povo Cabo-verdiano, possibilidades de emprego. O peixe aparece como componente importante na alimentação da população, tendo papel decisivo na questão da segurança alimentar e, por ser fonte de proteína animal de baixo custo para a população, requer que a sua exploração seja feita em moldes sustentáveis, perpetuando no tempo a disponibilidade desse recurso para toda a sociedade. A pesca é uma das principais atividades económicas da zona costeira da Ilha do Sal, além de ser uma importante atividade de subsistência para as três comunidades pesqueiras da ilha. Com o objetivo de discutir caminhos sustentáveis para a atividade, iremos refletir sobre a sustentabilidade da pesca artesanal na comunidade da Palmeira, Ilha do Sal, Cabo Verde. Numa comunidade como Palmeira, onde a pesca é tipicamente artesanal, encontramos diversos elementos que garantem a sustentabilidade da atividade, tais como o uso predominante dos recursos naturais renováveis e a diversidade de espécies capturadas. Conhecer e desenvolver novos mecanismos que visam educar, criar políticas sustentáveis para a atividade e gestão dos recursos, é importante para a nova conjuntura em que se vive. A educação e a organização dos pescadores, bem como a descentralização e a gestão participativa dos recursos pesqueiros, são condições fundamentais para a sustentabilidade da pesca.

Fishery has always been of great social economic importance for the coastal communities of Cape Verde, offering means of subsistence and employment opportunities due to their maritime vocation. Fish are important food component for the population, playing a decisive role in food safety. Since fishery is a source of low-cost animal protein, its exploration must be sustainable in order to be permanently available for the community. Fishing is one of the main economic activities of the coastal zone of island, besides being an important subsistence activity for the three fishing communities of the island. Aiming to discuss ways for sustainable activity, we will reflect on the sustainability of the handmade fishing in the community of Palmeira Sal Island, Cape Verde. In a community like Palmeira, where fishing is typically handmade, we find many elements that ensure the sustainability of the activity, such as the predominant use of renewable natural resources and the diversity of species caught. Meet and develop new mechanisms to educate, create sustainable policies for the activity and resource management, is important for the new environment in which we live. Education and organization of fishermen, as well as decentralization and participatory management of fishery resources, are fundamental to the sustainability of fisheries.

Diversity of Pentatomoidea (Hemiptera) in riparian forests of southern Brazil: taller forests, more bugs

Riparian forests are important features of any ecosystem, especially on grassland and savannah vegetation types. However, riparian forests in southernmost Brazil have received much less attention than elsewhere. This is the first quantitative study of pentatomoid (Hemiptera) diversity in the Pampa biome, surveying riparian forests of brooks and rivers in the environs of the municipality of Bagé, Rio Grande do Sul state, southern Brazil. The aim was two-fold: taxonomic characterization of the fauna and a primary ecological study of bug diversity. Sweeping net and beating tray were used to sample trees and shrubs on the border of sampling sites; sampling was carried out during three consecutive days, from March 28th to 30th 2006. Overall 154 individuals of 32 species of Pentatomoidea were captured, almost all species are new records for the local fauna. Taller forest canopy sites had higher abundance overall and higher species richness than shorter forest canopy sites. Of the 32 species, 11 were singletons and four were doubletons. There were no differences for pentatomoid species composition between the two environments differing in vegetation structure. Association to the Pampa biome of the most abundant species found are discussed. Although based on a rapid assessment protocol of faunal inventories, our results add important bioecological information to the pentatomoid fauna of the Pampa biome, especially associated to riparian forests.

The economic tragedy of the XXth Century: Growth in Africa

The dismal growth performance of Africa is the worst economic tragedy ofthe XXth century. We document the evolution of per capita GDP for thecontinent as a whole and for subset of countries south of the Saharadesert. We document the worsening of various income inequality indexesand we estimate poverty rates and headcounts. We then analyze some ofthe central robust determinants of economic growth reported bySala-i-Martin, Doppelhofer and Miller (2003) and project the annual growthrates Africa would have enjoyed if these key determinants had taken OECDrather than African values. Expensive investment goods, low levels ofeducation, poor health, adverse geography, closed economies, too muchpublic expenditure and too many military conflicts are seen as keyexplanations of the economic tragedy.

Economic booms, trade deficits and economic policy

Many economic booms have been accompanied by realexchange rate appreciations, large trade defcits -whichhave sometimes persisted after the return to the initialexchange rate parity- and a deteriorating traded sector.Those circumstances have typically raised the questionof the de-sirability of some stabilization policy. We show that the dynamics induced by an expectedproductivity shock in an economy where the capital stockis non-mobile across sectors, match those circumstances.Furthermore, we obtain that credit market imperfectionstend to exacerbate trade deficits, and to cause aninefficient capacity reduction in the traded sector.Some stabilization policies are explored.

An economic theory of church strictness

This paper makes several contributions to the growing literatureon the economics of religion. First, we explicitly introduce spatial-location models into the economics of religion. Second, we offer a newexplanation for the observed tendency of state (monopoly) churches tolocate toward the "low-tension" end of the "strictness continuum" (ina one-dimensional product space): This result is obtained through theconjunction of "benevolent preferences" (denominations care about theaggregate utility of members) and asymmetric costs of going to a moreor less strict church than one prefers.We also derive implications regarding the relationship between religiousstrictness and membership. The driving forces of our analysis, religiousmarket interactions and asymmetric costs of membership, high-light newexplanations for some well-established stylized facts. The analysis opensthe way to new empirical tests, aimed at confronting the implications ofour model against more traditional explanations.

Diversity of social wasps (Hymenoptera, Vespidae, Polistinae) in three fragments of semideciduous seasonal forest in the northwest of São Paulo State, Brazil

Human exploitation of the forest in the northwest of São Paulo State has generated enormous fragmentation of that forest. Such disturbance has reduced the populations of insects in general. This work was a survey of social wasps (Hymenoptera, Vespidae; Polistinae) in three areas in different stages of regeneration: Paulo de Faria - SP (435 ha), Pindorama - SP (128 ha) and Neves Paulista - SP (1 ha). These three areas were chosen for comparative purposes. To capture the wasps, it was used: active collecting with attractant liquid (solution of water, salt and sugar) with the aid of a dorsal spray bag. During the period from July to December 2006, 414 social wasps were collected in Paulo de Faria, constituting seven species belonging to four genera; 111 social wasps were collected in Pindorama, constituting six species belonging to four genera, and 129 social wasps were collected in Neves Paulista constituting 12 species belonging to seven genera. In order to compare these three areas ecological indexes were calculated. Neves Paulista had the greatest diversity, and Paulo de Faria presented greater abundance. These factors were probably caused by neighboring areas and ecological corridors, which were limited in Paulo de Faria and Pindorama.

Economic integration and corruption: The corrupt soul of the European Union

We study the link between corruption and economic integration. We show that if an economic union establishes a common regulation for public procurement, the country more prone to corruption benefits more from integration. However, if the propensities to corruption are too distinct, the less corrupt country will not be willing to join the union. This difference in corruption propensities can be offset by a difference in efficiency. We also show that corruption is lower if integration occurs. A panel data analysis for the European Union confirms that more corrupt countries are more favorable towards integration but less acceptable as potential new members.
