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 article investigates the determinants of newspapers’ provision for political opinion. I empirically examine the role of newspapers’ political preferences and market competition on newspapers’ decision to make endorsements. Regression results suggest that market competition turns newspapers more likely to make endorsements. Results from a simple model show that newspapers’ ideology determine their endorsements, making partisan papers more likely to make political recommendations and endorse challengers than non‐partisan newspapers.  相似文献

A bstract . Vilfredo Pareto has been labelled a fascist and 'a precursor of fascism' largely because he welcomed the advent of fascism in Italy and was honored by the new regime. Some have seen in his sociological works the foundations of fascism. This is not correct. Even fascist writers did not find much merit in these works, and definitely condemned his economic theories. A s a political thinker he remained a radical libertarian till the end, and continued to express serious reservations about fascism, and to voice opposition to its basic policies. This is evident from his correspondence with his close friends. There are strong reasons to believe that, had he lived long enough, Pareto would have revolted against fascism.  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

There have been many previous studies of technical inefficiency in rice production in the Philippines, but none has focused simultaneously on production risk and technical inefficiency at the farm level. Rice production is inherently risky because of the heterogeneous production environment. In this study, we analyze technical inefficiency in a rainfed lowland rice environment in Central Luzon using a stochastic frontier production function with a heteroskedastic error structure. An 8‐year panel dataset collected from 46 rainfed rice farmers was used to estimate flexible functional specifications. Over the whole period, the average technical efficiency was found to be 79 percent. Results indicate that there is a high degree of variability in technical efficiency estimates, which can be attributed to the instability of farming conditions in the rainfed lowland environment. Mean output was signifificantly influenced by area planted to rice, labor and the amount of fertilizer used. Consequently, these inputs were found to be risk‐increasing, whereas herbicide was found to be a risk‐reducing input.  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

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

This paper examines the statistical properties of the bilateral real exchange rates of the U.S. vs. France, Germany, and the U.K. during the Post-Bretton-Woods period, and draws implications on the Purchasing Power Parity (PPP) hypothesis. Contrary to traditional studies that consider only unit root and stationary processes to describe the real exchange rate behavior, this paper considers an in-between process, the locally persistent process. The empirical results demonstrate the following two findings: (1) Locally persistent processes describe the real exchange rate movements better than unit root and stationary processes, which implies that PPP reversion occurs and PPP holds in the long-run. (2) The confidence intervals for half-life deviations from PPP under local persistence tend to be narrower than those obtained by assuming the ADF and the local-to-unity models.  相似文献
