La revolución de las TIC ha generado un alto riesgo de deslocalización de las tareas más comercializables en el sector de los servicios. Se revisan aquí estudios que proponen indicadores de comerciabilidad de los servicios, exploran las implicaciones de su deslocalización y desarrollan modelos teóricos al respecto. Tanto el nivel de calificación requerido como la comerciabilidad podrían ser determinantes clave de los efectos sobre los salarios y el empleo. Sin embargo, la falta de definiciones consensuadas de comerciabilidad y de datos fiables sobre el comercio de servicios, junto con la dificultad de evaluar la competencia de las importaciones a niveles desagregados, obstaculizan el avance de los estudios empíricos y descubren áreas para futuras investigaciones. 相似文献

Recent theoretical findings in the trade literature suggest that economic integration agreements (EIAs) not only increase the level of trade but also make it more stable and predictable. This paper proposes a Hausman–Taylor quantile regression approach to identify the causal effect of EIA membership on trade predictability. The proposed methodology accounts for group effects in the gravity equation and is computationally efficient. Our results corroborate the theoretical findings that EIAs make trade more stable and predictable and this conclusion is even stronger for deeper EIAs. 相似文献

Although the original concept of international new ventures included the geographic configuration of value activities, the subsequent development of the literature has gradually abandoned the concern about the geographic configuration of both input sourcing and output marketing to concentrate almost exclusively on the latter. Therefore, this paper argues that there is a need to re-focus the research so as to figure out how and why some companies are borderless. Borderless firms are defined as the result of the combination, early on, of geographically dispersed resources and capabilities, defying the home-base logic. A borderless firm presents the following characteristics (or a combination of them) from inception (or shortly thereafter): (i) value-added activities dispersed across different countries and regions; (ii) entrepreneurs not bounded by a home base; (iii) multinational founders and/or management teams; and (iv) a multinational workforce. To enquiry into this issue, the study uses five case studies of borderless firms. The results advance the understanding of the motives and processes behind the development, early on, of a borderless configuration of value activities. 相似文献

Supplier evaluation has assumed a strategic role in determining competitiveness of large manufacturing companies. An increasing number of researches have been devoted to the development of different kind of methodologies to cope with this problem. Nevertheless, while the number of applications is growing, there is little empirical evidence of the practical usefulness of such tools with a dichotomy between theoretical approaches and empirical applications. Considering this evidence, the goal of this paper is to contribute to understand the above dichotomy by implementing, in a corporate environment, a model for supplier evaluation based on the Analytical Hierarchical Process (AHP), one of the most prominent methodologies used to address the problem. The analysis of the implementation process of the methodology allows the identification of strengths and weaknesses of using formalized supplier selection models to tackle the supplier evaluation problem, also highlighting potential barriers preventing firms to adopt such methods. Relevant issues arising from the application and managerial implications for both customer and suppliers are discussed. 相似文献

Food price inflation in Brazil in the 12 months to June 2008 was 18%, whereas overall inflation was 7%. Using spatially disaggregated monthly data on consumer prices and two different household surveys, we estimate the welfare consequences of these food price increases, and their distribution across households. Because Brazil is a large food producer, with a predominantly wage‐earning agricultural labour force, our estimates include general equilibrium effects on market and transfer incomes, as well as the standard estimates of changes in consumer surplus. Although the expenditure (or consumer surplus) effects were large, negative and markedly regressive everywhere, estimates of the market‐income effect were positive and progressive, particularly in rural areas. Because of this effect on the rural poor, and of the partial protection afforded by increases in two large social assistance benefits, the overall impact of higher food prices in Brazil was U‐shaped, with middle‐income groups suffering larger proportional losses than the very poor. Nevertheless, as Brazil is 80% urban, higher food prices still led to a greater incidence and depth of poverty at the national level. 相似文献

Finding an efficient method for sampling micro- and small-enterprises (MSEs) for research and statistical reporting purposes is a challenge in developing countries, where registries of MSEs are often nonexistent or outdated. This lack of a sampling frame creates an obstacle in finding a representative sample of MSEs. This study uses computer simulations to draw samples from a census of businesses and non-businesses in the Tshwane Municipality of South Africa, using three different sampling methods: the traditional probability sampling method, the compact segment sampling method, and the World Health Organization's Expanded Programme on Immunization (EPI) sampling method. Three mechanisms by which the methods could differ are tested, the proximity selection of respondents, the at-home selection of respondents, and the use of inaccurate probability weights. The results highlight the importance of revisits and accurate probability weights, but the lesser effect of proximity selection on the samples' statistical properties. 相似文献

Conditional Cash Transfers, Schooling, and Child Labor: Micro-Simulating Brazil's Bolsa Escola Program 总被引:1,自引:0,他引:1

A growing number of developing economies are providing cashtransfers to poor people that require certain behaviors on theirpart, such as attending school or regularly visiting healthcare facilities. A simple ex ante methodology is proposed forevaluating such programs and used to assess the Bolsa Escolaprogram in Brazil. The results suggest that about 60 percentof poor 10- to 15-year-olds not in school enroll in responseto the program. The program reduces the incidence of povertyby only a little more than one percentage point, however, andthe Gini coefficient falls just half a point. Results are betterfor measures more sensitive to the bottom of the distribution,but the effect is never large. 相似文献

This paper generalizes the informational environment of the Rock model to address empirical evidence and conjectures that cannot be addressed within the standard model based on informed and uninformed investors such as underpricing being positively related to market returns observed prior to the IPO, the number of IPOs being positively related to market returns, underpricing being partly predictable based on public information, and the return to uninformed participation being negative overall but positively related to market returns observed prior to the IPO. Finally, the model suggests that a positive relation between market returns and underpricing need not represent an inefficiency in the pricing of IPOs. 相似文献
