This paper examines the presence of a pro-poor bias in the existing structure of protection of six Sub-Saharan African (SSA) countries, Burkina Faso, Cameroon, Côte d'Ivoire, Ethiopia, Gambia, and Madagascar. We build on a simple agricultural household production model and we propose an extension to include adjustments in labor income. Our approach, which can be implemented without repeated cross-sections of household level data, suits well the data constraints in SSA. It also allows us to capture the heterogeneity in trade protection at the tariff line level. The pro-poor bias indicators suggest that SSA's trade policies tend to be biased in favor of poor households, as these policies redistribute income from rich to poor households. This is because protection increases the agricultural prices of goods that are sold by African households and this effect dominates both the impacts of higher consumption prices and the strong Stolper–Samuelson effects that benefit skilled over unskilled workers. 相似文献

Estimating the social cost of pesticide use: An assessment from acute poisoning in Brazil 总被引:2,自引:0,他引:2
The intensive use of pesticides in countries like Brazil has ignored structural and institutional shortfalls, such as the lack of workforce training for the new, difficult to implement technologies, and the institutional vulnerability of the environmental protection, health, and safety sectors. As a result we have “invisible” or social, environmental and health costs which end up being socialised with the farmer, in general, having no incentives to recognise and internalise them. This study is intended to review and develop this problem in the light of the Brazilian reality. To this end, we make use of an empirical exercise to illustrate estimation of the social cost associated with acute poisoning by pesticide using the PREVS/IBGE data (Harvest Forecast Research) in the state of Paraná, Brazil. The results suggest that, for maize, the costs of acute poisoning could represent 64% of the benefits of using herbicides and insecticides, and, in the best of hypotheses, when some risk factors are eliminated, they may reach 8% of the benefits of the use of these products. Similarly, when we examine future scenarios for five and ten years, we find less encouraging results, as in ten years the costs of acute poisoning could reach around 85% of the benefit of using insecticides and herbicides for maize. However, there is the encouraging news that, if preventive measures were taken during this time, the gains would be considerable, about 6.5 times greater. We conclude that an assessment of the real benefits involved with pesticides in Brazil is required, principally in regard to the smallholder, where farmers need more training in the use — or even the elimination — of these hazardous substances. There are sustainable technological options available which are economically efficient, especially if we consider the social, environmental and health costs. In this context it is worth highlighting the role of regulatory measures as a mechanism which can reorient generation of negative external costs through the reduction of current incentives in the socialisation of private costs. 相似文献

Mercosur appears as an interesting case study for analyzingthe determinants of exceptions in regional trade agreements.Its member countriesArgentina, Brazil, Paraguay, andUruguayintended to make Mercosur a full customs unionby January 1995. This goal turned out to be too ambitious, andthe Protocol of Ouro Preto and other agreements signed in December1994 led to a hybrid solution. Overall, out of a total of 9,119tariff lines, around 30 percent are subject, in at least onemember country, to either external deviations from the commonexternal tariff or internal deviations from free trade. Thusan important set of holes remains under the existing agreement,leading some authors to consider Mercosur an incomplete customsunion. This article compares the results of the theoretical literatureon endogenous tariff formation with evidence from Mercosur.The results show that Mercosur's common external tariff andmember countries' deviations from it and from internal freetrade can be explained by sector or industry lobbying as predictedby the endogenous tariff literature. If a viable political economyis a key to success, then Mercosur is here to stay. 相似文献

This paper explores the extent to which discrimination against foreign applicants in the trademark registration process can be used as a “behind‐the‐border” barrier to imports. Prima‐facie evidence shows that in some developing countries the ratio of trademark registrations to applications is much higher for national than for foreign applicants, which is consistent with the notion of discrimination against foreign firms. A simple model is developed that suggests that incentives to discriminate are stronger when foreign firms manufacture products that are close in quality to the goods produced by domestic firms. This hypothesis is then tested and empirically confirmed in three of the four countries in our sample, suggesting that discretion and discrimination in the trademark registration process can sometimes be used as a protectionist tool. 相似文献

This article studies the determinants of the labor force participation of the elderly and investigates the factors that may account for the increase in retirement in the second half of the last century. We develop a lifecycle general equilibrium model with endogenous retirement that embeds Social Security legislation and Medicare. Individuals are ex ante heterogeneous with respect to their preferences for leisure and face uncertainty about labor productivity, health status and out-of-pocket medical expenses. The model is calibrated to the U.S. economy in 2000 and is able to reproduce very closely the retirement behavior of the American population. It reproduces the peaks in the distribution of Social Security applications at ages 62 and 65 and the observed facts that low earners and unhealthy individuals retire earlier. It also matches very closely the increase in retirement from 1950 to 2000. Changes in Social Security policy – which became much more generous – and the introduction of Medicare account for most of the expansion of retirement. In contrast, the isolated impact of the increase in longevity was a delaying of retirement. 相似文献

After the wars of independence in the first half of the nineteenthcentury, Latin American countries embarked on a process of insertioninto the world economy, opening their doors to foreign investmentand specializing in the exportation of raw materials. In freemarkets and in an alignment with the British imperial economicsystem, Latin American elites saw a road for economic prosperityand political stability. Between the 1880s and 1914, Latin Americabecame more integrated into the 相似文献

This study examines how managers approach marketing measures in a Brazilian context. Using data from a large-scale empirical study in Brazil, we focus on managers' views of the practices in marketing measurement and identify which indicators they emphasize. The findings, which reflect Brazilian managerial practice, indicate that managers use a combination of metrics. Items such as total number of customers, number of complaints, and customer satisfaction are among the most known and most used metrics. When addressing the 10 most relevant metrics results yield 4 groups, including customer vision, financial, product vision, and market and innovation. Indicators pertaining to customer vision are the most important to Brazilian managers. Furthermore, we discuss the results and draw comparisons with similar studies conducted in the United Kingdom and China. Finally, we present conclusions and avenues for future research. 相似文献

Nonlinear regression models have been widely used in practice for a variety of time series and cross-section datasets. For purposes of analyzing univariate and multivariate time series data, in particular, smooth transition regression (STR) models have been shown to be very useful for representing and capturing asymmetric behavior. Most STR models have been applied to univariate processes, and have made a variety of assumptions, including stationary or cointegrated processes, uncorrelated, homoskedastic or conditionally heteroskedastic errors, and weakly exogenous regressors. Under the assumption of exogeneity, the standard method of estimation is nonlinear least squares. The primary purpose of this paper is to relax the assumption of weakly exogenous regressors and to discuss moment-based methods for estimating STR models. The paper analyzes the properties of the STR model with endogenous variables by providing a diagnostic test of linearity of the underlying process under endogeneity, developing an estimation procedure and a misspecification test for the STR model, presenting the results of Monte Carlo simulations to show the usefulness of the model and estimation method, and providing an empirical application for inflation rate targeting in Brazil. We show that STR models with endogenous variables can be specified and estimated by a straightforward application of existing results in the literature. 相似文献

This article considers a real business cycle model with establishment level dynamics and uses it to analyze the effects of firing taxes. It finds that firing taxes can have significant consequences on business cycle fluctuations, that the largest effects are on aggregate employment, and that even relatively small firing taxes have substantial effects. A significant contribution of the article is computational: It describes how to use standard linear‐quadratic methods to solve for a stochastic equilibrium of an (S,s) economy with tax distortions. 相似文献

The world faces a double crisis: the food crisis and energy crisis. The agribusiness is at the center of this societal dilemma, involving aspects from the volumes of production and productivity up to the way to produce them. Furthermore, there is a discussion about the need for establishing a trade-off between production of food and energy. A central aspect regarding the way of production is on how existing resources to be used and, especially, when its degradation occurs. These discussions indicate the need for interpretation and for proposition of solutions, under a complex perspective, for this double crisis. Accordingly, this paper proposes a framework for the interpretation of complex problems and for initiatives focused on sustainability that was applied to the context of food, energy and biofuel crisis. The theoretical background comprises two theories. The first is the complexity theory, which enabled the proposition of a system to understand the reality, distinguishing and combining the several existing realities without losing the global notion; The second is the sustainability theory, which enabled the systematization of stages for the planning of more sustainable actions to operate in that context; Lastly, it was possible to infer desirable characteristics that other theories could also be included, aiming to propose solutions that are more appropriated for this specific context. 相似文献
