The study analyzes the convergence of the labor productivity in the Brazilian agricultural sector in the nineties, comparing it with its productivity in the other sectors and projecting its future behavior through Markov matrices. The results indicate that the Brazilian states are diverging in the labor productivity in the agricultural sector. Some states will move to a high level and others to a low level of labor productivity. In five of the other sectors of the Brazilian economy there will be a convergence of the states with regard to the labor productivity. In three of these five sectors the states will converge to a low level of labor productivity; in one sector they will converge to two classes of low productivity and in another sector the states... |

Whether food demand is "converging" is tested in two ways. First, the convergence of food expenditures among 18 high-income countries is examined from 1990 to 2004. Convergence is apparent in total expenditures, cereals, and meats, even after correcting for differences in income and levels of protection. Second, specific food retailing and product introduction patterns are examined for the US, Canada, and four northern European countries for the past two decades. These show increasing shares for retail outlets selling standardized products, and increased preference for convenience, upscale, and natural product attributes across all six countries. |

Dolphins and African apes are distantly related mammalian taxa that exhibit striking convergences in their socioecology. In both cetaceans and African apes, two or more closely related species sometimes occur in sympatry. However, detailed reviews of the ways in which sympatric associations of dolphins and apes are similar have not been done. As field studies of dolphins and apes have accumulated, comparisons of how the two groups avoid direct food competition when in sympatry have become possible. In this paper we review sympatric ecology among dolphins and African apes, and examine convergences in species-associations in each taxa. We review evidence for hypotheses that seek to explain avoidance of food competition, and consider whether ape-dolphin... |

In the present study, we assessed the ecomorphology of two species of Astyanax in streams with different substrates found in the Rio São Francisco Basin. The dominant substrate of each stream was defined as either "fine" (0 to 2 mm), "gravel" (2 to 250 mm), "rock" (> 250 mm), or "leaf bank". We analyzed a total of 22 ecomorphological attributes of Astyanax intermedius Eigenmann, 1908 (127 individuals) and Astyanax rivularis (Lütken, 1875) (238 individuals) adults. We detected significant ecomorphological differences between the populations of A. rivularis and A. intermedius from habitats with different types of substrates. However, the two species did not show the same morphological differences depending on the type of substrate. These results confirmed... |

Theil’s inequality index is used to measure convergence in 14 Organization for Economic Cooperation and Development (OECD) countries in terms of per capita income, per capita government and investment expenditures, and industrial employment. Results indicate that all four variables have converged over the sample period, 1950-1988. Next, the indices of the four variables are made dynamic by using pairwise cointegration and Johansen’s I(2) multi-cointegration tests. These tests indicate that the four inequalities are cointegrated; that is, there exists a long-run equilibrium between the four inequalities of the 14 OECD countries. However, the inequality in per capita government expenditure has no effect on the G-7 equilibrium when analyzed without the... |

The main objective of this paper is to analyse the structural changes in European Agri-food systems in the last 30 years in order to verify the presence of a convergence process towards a more homogeneous structure among EU countries. This analysis considers the relative importance of the main components of Agri-food systems (agriculture, food industry and food consumption) and how they change over time. The analysis of convergence utilise the European National Accounting Data (from the SEC2 Data Base of Eurostat) from 1970 to 2000 for twelve EU countries. We use tests of convergence on cross section data by countries, but also stochastic kernel methodologies to verify the dynamic evolution of groups of countries inside the EU. The results show there are... |

The purpose of this paper is to empirically analyze determinants of income-level convergence. Specifically, the effect of human capital on per capita income is estimated for 22 countries of the organization for Economic Cooperation and Development (OECD). Additionally, the effects of openness in international trade and investment and government expenditures on per capita income are estimated and evaluated. Human capital is modeled as a latent variable, and results indicate that it is a significant factor in explaining the variation of per capita income levels among the OECD countries. Further, the entire time path of human capital is utilized to explain deviations in per capita income. |

There is considerable interest in projections of future productivity growth in agriculture. Whether one is interested in the outlook for global commodity markets, future patterns of international trade, or the interactions between land use, deforestation and ecological diversity, the rate of productivity growth in agriculture is an essential input. Yet solid projections for this variable have proven elusive particularly on a global basis. This is due, in no small part, to the difficulty in measuring historical productivity growth. The purpose of this paper is to report the latest time series evidence on total factor productivity growth for crops, ruminants and non-ruminant livestock, on a global basis. We then follow with tests for convergence amongst... |
