Latin America is a region of sharp ethnic inequalities. Uruguay has usually been considered an exception to this pattern, although no data were available to confirm this assumption until recently. This article uses the Household Survey of 2006 to analyze the wage gap between Afro‐descendants and whites through OLS equations, decompositions, and quantile regressions. The analysis finds that discrimination explains approximately 50 percent of the racial wage gap for men and 20 percent for women. Discrimination operates partly through occupational segregation. Differences in schooling are the most important explanatory factor for the rest of the gap. Quantile regressions show that discrimination declines across percentiles for men. 相似文献

Abstract Using survival models, we test whether short-term changes in the labour market affect poverty duration. Data are from the Brazilian Monthly Employment Survey. Such a monthly dataset permits more accurate estimations of events than using annual data, but its panel follows households for a short period. Then methods that control for both right- and left-censoring should be used. The results are as follows: households with zero income are not those with the lowest chances of exiting; changes in aggregate unemployment do not affect poverty duration; and increasing wages in the informal sector has a negative effect on poverty duration. 相似文献

This paper describes the characteristics of Japanese foreign investment in Latin America. In examining FDI patterns, we identify the countries and industries most attractive to Japanese multinational corporations, the preferred modes of entry, and the post-entry performance of these subsidiaries. We find that most Japanese FDI has occurred in Brazil and Mexico, that joint ventures are the most common mode of entry, and that performance varies by country and mode. The observations have implications for three groups of executives: managers of non-Latin American firms, managers of Latin American firms, and public policy makers. 相似文献

This article discusses the organisational and institutional model of municipal company in the provision of urban infrastructure services in Portugal. The law recently enacted which defined the legal regime for the local business sector, as well as the growing awareness that the new public management models represent great advantages in comparison with the bureaucratic ones that characterise the traditional public administration, make this a current and relevant issue. For the purpose of investigating the viability of this provision model, this research encompasses three complementary analyses. First, the results obtained from a nationwide questionnaire on the features of municipal companies are analysed. Second, a SWOT matrix is constructed to examine the model of municipal company and, third, the total factor productivity (TFP) of these organisations is determined using the index number theory, in order to evaluate their performance and compare it with that of the traditional bureaucratic models. Although the concept of municipal company is based on noble principles and, in theory, it shows advantages compared to other means of service provision, this research points to very negative results regarding the model and leads to the conclusion that the aimed benefits are not achieved in Portugal. There are many causes contributing to this effect, but the political patronage of these companies and the lack of technical competence are presumably two of the most significant ones. 相似文献

This article argues that since 1949, the relationship between Israel and Jordan has depended primarily on their interactions with a Third Actor--identified as Egypt from 1949 to the mid-1970s, and as the Palestinians thereafter. Conflict between Israel and Jordan always follows conflict one or both nations have with the Third Actor. The analysis suggests a cyclical and hierarchical allegiance condition, in which Jordan switches from an alliance with Israel to an alliance with the Third Actor. Jordan cooperates with Israel--even if it itself engages in conflict with the Third Actor--until Israel engages in conflict with the Third Actor, at which point Jordan realigns with the Third Actor against Israel. This analysis suggests that to avoid an Israeli-Jordanian conflict, Israel must reach an agreement with the Palestinians regarding the existence and borders of a Palestinian state. Such an agreement, however, may not guarantee permanent peace between Israel and Jordan, as regional tensions fueled by controversy regarding the existence and legitimacy of the Jordanian Hashemite monarchy may rise again. Thus, even if a Palestinian state were established, the current peace between Israel and Jordan might be transitory. 相似文献

In this work, two methods were developed to determine herbicides paraquat, glyphosate, and aminomethylphosphonic acid (AMPA) in marijuana samples by capillary electrophoresis. For paraquat analysis, sample was extracted with aqueous acetic acid solution and analyzed by capillary zone electrophoresis with direct UV detection. The running electrolyte was 50 mmol/L phosphate buffer (pH 2.50). For glyphosate and AMPA, indirect UV/VIS detection was used, as these substances do not present chromophoric groups. Samples were extracted with 5 mmol/L hydrochloric acid. The running electrolyte was 10 mmol/L gallic acid, 6 mmol/L TRIS, and 0.1 mmol/L CTAB (pH = 4.7). The methods presented good linearity, precision, accuracy, and recovery. Paraquat was detected in 12 samples (n = 130), ranging from 0.01 to 25.1 mg/g. Three samples were positive for glyphosate (0.15–0.75 mg/g), and one sample presented AMPA as well. Experimental studies are suggested to evaluate the risks of these concentrations to marijuana user. 相似文献

The contribution of lobby regulation initiatives in addressing political corruption in Latin America
Luiz Alberto dos Santos Paulo Mauricio Teixeira da Costa 《Journal of Public Affairs (14723891)》2014,14(3-4):379-391
For most of its history, Latin America has lived under authoritarian and elite rule where public decisions were often crafted in the shadows by cabinets and parliaments to the benefit of a small minority. Recently, the development of participatory political systems has brought some transparency to the policy-making process. Such scrutiny reveals evidence of the capture of aspects of policy-making by private interests that use obscure strategies to achieve their political goals. As a consequence, a widespread movement for regulating the role and tactics of interest groups emerged, which is seen as a necessary step to address the root causes of political corruption. This article provides an overview of efforts to regulate lobbying in Latin America. It explains attempts at regulation in four countries (Argentina, Brazil, Chile, and Peru), evaluates the level of success of these efforts, and assesses prospects for the future regarding reducing corruption through the instrument of lobby regulations. The authors argue that such regulations alone cannot eliminate political corruption. However, lobby regulations can contribute to increased transparency and aid in developing an anti-corruption culture. It will be shown that lobby laws in Latin America exhibit many of the problems long identified with similar regulations across western democracies. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献
