The current global food crisis has reemphasized the costliness of Africa's failure to achieve food security and poverty reduction. The instrument by which other more successful developing countries achieved these outcomes was a “Green Revolution” in agriculture. While previous research has provided largely discursive appraisals of the viability of an African Green Revolution, this article adopts a more rigorous methodology to address that question. First, an economy‐wide multimarket model, augmented with existing poverty–growth elasticities, is developed to assess the likely impacts of a rapid acceleration in food production (of the kind witnessed in previous Green Revolutions) on food prices, consumption and demand, farmer revenue, and poverty. Our results suggest that a rapid growth in staple production, together with more integrated regional markets, would reduce food prices by roughly 20–40% for consumers and 10–20% for producers among the major crops. This translates into a large rise in farm revenues, annual agricultural growth rates of 6.5% or higher, broader income growth and food security, and over 70 million Africans being lifted out of poverty. The article concludes by emphasizing the kinds of fundamental policy actions and resources that would be required for achieving these outcomes. 相似文献

今天我主要讲的是关于全球货币政策及利率变化对中国的影响,首先我认为有一个现象值得我们注意,就是中美两国的经济发展状况出现了不一致性,美国的经济增长开始减速而中国的经济在不断攀升,另外美国的利率预计会下调,而中国的利率在提高. 相似文献

The effects of employee ownership, broadly defined, are estimated for a sample of Polish producer co-operatives in three industries during 1976-8, i.e. when Poland was a centrally planned economy. The results indicate that, in general, increasing either worker participation in control and/or in economic returns provides positive effects on productivity. The pattern of the different effects of employee ownership varies significantly across sectors. This new evidence strongly suggests that workers within Soviet-type economies are responsive to economic incentives. Together with existing theoretical and empirical evidence for both Eastern and Western European firms, the findings suggest a larger role for employee ownership than typically either currently exists or that is under serious consideration in most restructuring economies. 相似文献

Motivated by investment-based asset pricing, we show that two firm fundamentals, investment and profitability, have substantial predictive power for REIT returns. The return predictability of investment and profitability is not subsumed by conventional models and can be useful for understanding the cross section of expected REIT returns. To illustrate, we construct an investment-based factor model for REITs that consists of a market factor, an investment factor, and a profitability factor. The investment-based model outperforms conventional models in capturing well-known cross-sectional patterns in REIT returns. Our findings suggest that incorporating investment-based asset pricing can be a promising direction for future real estate finance research. 相似文献

There is limited consensus on how to define informal employment in South Africa, but in the South African and international literature the three most common ways of capturing informal employment are the enterprise, employment relationship and worker characteristics approaches. This paper reviews the methods used by Statistics South Africa to measure informal employment before and after the introduction of the Quarterly Labour Force Survey, and other recently proposed methods. It then investigates the congruence, if any, between five measures of informality used in 2009. It finds that 94.7% of the self-employed are informal according to at least one definition, but only 62.6% according to all five combined. In addition, these two proportions are only 67.7% and 6.9% respectively in the case of informal employees. Econometric analysis is conducted to further investigate the differences between these measures. 相似文献

This research engages with the problem of company–community conflict in mining. The inequitable distributions of risks, impacts,
and benefits are key drivers of resource conflicts and are likely to remain at the forefront of mining-related research and
advocacy. Procedural and interactional forms of justice therefore lie at the very heart of some of the real and ongoing challenges
in mining, including: intractable local-level conflict; emerging global norms and performance standards; and ever-increasing
expectations for the industry to translate high-level corporate social responsibility policy into on-the-ground practice.
This research focuses on the “process” aspects of resource conflicts through an examination of existing grievance-handling
procedures at six mining operations where company–community conflict was present. In their current form, and on their own,
the six mechanisms were found to be insufficient in their capacity to advance justice. The authors argue that if the overall
objective of global norms is that companies construct and perform grievance handling in ways that strongly preference just
practices, then “mechanisms-in-practice” must be better understood and constructively critiqued along all justice dimensions. 相似文献

One of the most pressing socio-economic problems of the South African economy is high youth unemployment. Recent studies only briefly examined how youths have fared since the transition by comparing the 1995 October Household Survey with a Labour Force Survey, and hardly investigated whether the discouraged workseekers are different from the unemployed. This paper re-examined youth unemployment trends in the 2008–12 Quarterly Labour Force Surveys, before comparing the characteristics of discouraged workseekers and narrow unemployed. Whether different policies are needed to boost youth employment in each group is also discussed. 相似文献

Legislation outlined proposed changes in Galician Health Centres. This allowed us to set down the theory about personal and organizational Information–Influence Matrices and then Frameworks of Issues for the interactions between an individual Financial Manager and a Health Centre Co-ordinator, as well as the proposed organizational changes into a new system [Purdy DE, Gago S. Extending influence and accounting use: developing the frameworks to incorporate Galician legal matters about the proposed healthcare changes with managers and organizations for empirical study. Critical Perspectives on Accounting; in press].Evidence from a longitudinal study covering January 1997 and December 2001, indicated the suitability of these types of Matrices and Frameworks of Issues to analyse conversational data.Results agreed with anticipations at a personal level—wholly for a co-ordinator and partly for the Financial Manager. Differences between the findings and our anticipated Financial Manager's framework are straightforward and we have amended our Framework accordingly. The organization level has followed our anticipations though only 15% of Health Centres had continued with the new system, 85% remained working with the old system.Galician law contained aspirations for changing healthcare with autonomous Health Centres. Spanish health policies and budget laws have inhibited moves to change, as well as the actions of the professionals involved. 相似文献
