The global geographical balance of food and agricultural R&D spending is shifting, characterized by a declining U.S. share and a rising middle-income-country share, propelled heavily by the rapid rise of spending in China. Based on our newly compiled data, we estimate that China now outspends the United States on both public and private food and agricultural research on a purchasing power parity basis. The public-private orientation of the research has also changed markedly, with the private sector now accounting for around two-thirds of the food and agricultural R&D spending total in both China and the United States. Our estimates indicate that China’s private sector tilts heavily towards post-farm R&D activities, whereas the U.S. private sector is split more evenly between on-farm and post-farm spending. While the intensity of Chinese investment in food and agricultural R&D (relative to agricultural GDP) is beginning to grow, it still lags well behind the food and agricultural R&D investment intensities of the United States and other higher-income Asian countries (e.g., Japan and South Korea). The development regularities we reveal in the longer-run trends are indicative of future R&D investment patterns with potentially profound long-run implications for the size, shape and accessibility of the global stocks of scientific knowledge that underpin food and agricultural sectors worldwide.  相似文献

Over 1994–2010, adult dietary quality in the United States increased by 10 percent. We find a shift in consumption between at-home and away-from-home food played a relatively minor role as compared to changes in demographics and educational attainment. The two largest contributors we identify include an increased usage of nutritional information and a shift away from relying heavily on price, taste, storability and ease of preparation when shopping for food. Our findings suggest nutrition policy discussions could focus on further shifting attitudes/preferences towards healthier diets while allowing consumers to better extract nutrition information when making food choices.  相似文献

This paper analyses individuals who never hold a unionized job and are never represented by a union ('never-unionized'). Using 21 waves of the National Longitudinal Survey of Youth 1979 data to track individuals starting at age 15 or 16, we show that by the time workers are 40 or 41 years old, one-third of them are never-unionized, and a convex never-unionization trajectory suggests that most of them will remain never-unionized. An analysis of the demographic and labour market characteristics of the never-unionized further suggests two types of never-unionized workers — those who lack opportunities for obtaining unionized jobs and those who lack the desire to obtain unionized jobs.  相似文献

This article considers whether organized labour's engagement with shareholder activism represents a shift in unions’ traditional stakeholder preferences on corporate governance under pension fund capitalism. It does so in light of recent critiques of the class power thesis of corporate governance which suggest greater fluidity and fragmentation in labour's approach. Adopting a diverse case study strategy to compare organized labour's actions in the United States, United Kingdom and France, the article explains these activities as innovative strategies, similar to other revitalization initiatives, designed to advance traditional agendas by alternative means. The article thus concludes that, while organized labour's shareholder activism is unexpected under the class power thesis, its core preferences remain largely unchanged.  相似文献

Trade unions are frequently criticized for excluding women from skilled crafts by denying them training. This article examines this argument by eestimatin the retention and attrition probabilities of men and women in the joint union‐management and the unilateral employer‐sponsored apprenticeship programs. While men, on average, have higher retention and lower attrition rates than women, joint sponsorship raises women's graduation probability above (and lowers their quit probability below) those of men or women apprentices in unilateral programs.  相似文献

There seems to be high interest in the question of food loss and food waste. The comments take up the article in Food Policy on “Total and per capita value of food loss in the United States”. It is argued that the methodology of calculating the food loss is questionable. Consequently, the estimates are highly inflated; therefore the authors do not provide accurate information for policy makers as intended.  相似文献

This study is the first to examine the relationship between conspicuous demand and housing price dynamics. We hypothesize that conspicuous consumers would want high‐end homes to signal their wealth and this housing consumption behavior would induce greater deviations from fundamental house prices. We test this by using a unique dataset that matches the consumers’ appetite for nonhousing luxury goods from Google Insights for Search to housing premiums that they pay for high‐end houses in U.S. Metropolitan Statistical Areas (MSAs) during 2004–2011. The estimation results demonstrate that controlling for a wide range of MSA demographic and economic characteristics, conspicuous demand has a significant, positive relationship with housing premiums. This relationship varies spatially and temporally. Conspicuous demand has a stronger relationship with a price increase in high‐end homes in MSAs with a steady, higher housing premium than in MSAs with a volatile, lower premium during the boom period. In MSAs with a steady, higher housing premium, the relationship remains significant even during the bust period, potentially contributing to maintaining higher housing premiums.  相似文献

This article assesses the predictive power of variables that measure market tightness, such as seller's bargaining power and sale probabilities, on future home prices. Theoretical insights from a stylized search‐and‐matching model illustrate that such indicators can be associated with subsequent home price appreciation. The empirical analysis employs listings data on residential units offered for sale through a real estate broker in the Netherlands and for certain U.S. regions. Individual records are used to construct quarterly home price indices, an index that measures seller's bargaining power and (quality‐adjusted) home sale probabilities. Using conventional time‐series models we show that current sale probabilities and bargaining power can significantly reduce home price appreciation forecast errors and help to predict turning points in local area housing markets. The measures and approaches in this article help to demonstrate ways in which researchers and practitioners can leverage listings data to gain knowledge about the current and future state of the housing market.  相似文献

Trust and commitment are central to the relational mediators model of relationship marketing. Extant research suggests that trust enhances commitment, as a trusted partner is so highly valued that a channel member will invest in the relationship and put forth efforts to maintain that relationship. This study re-examines the causality between trust and commitment by comparing alternative models across three datasets (including the seminal Morgan and Hunt 1994 data). The results indicate that while trust enhances commitment, commitment can also erode trust. Several viable, theoretically-driven explanations for this negative effect are discussed, and propositions are developed for future research.  相似文献

High-value export-oriented agriculture is today considered as a means of integrating smallholders into the world economy. This paper examines the geographic and organisational changes that have taken place in the fresh pineapple sector over the past 50 years. We begin with a historical analysis of the changes in leadership among producer countries, namely the dethroning of Côte d’Ivoire by Costa Rica. We show that this geographical shift has been accompanied by massive organisational changes: the pineapple sector is increasingly driven by large downstream actors who derive their power from the ability to impose their definition of quality to the whole chain, and from economies of scale and scope. Although varietal innovation plays a key role throughout the period, commercial and logistical innovation are of increasing strategic importance. However, because of the constraints imposed by the concerned supply chains, small farmers risk being excluded or marginalized.  相似文献

Small-scale farming involves millions of households in the EU and plays an important role in the rural economy. A significant percentage of these farms produce commodities for the market. This productive dimension is often overlooked, however, as is the technical support needed by these farms. The privatization of national farm advisory systems (NFAS) has an impact on small-scale farming that should be better assessed. This paper, which looks at the characteristics of intangible services, helps demonstrate how the privatization of advisory services may have unexpected adverse effects on small farms. The dismantling of coordinating authorities has made these farms less visible as a target client. Less direct interaction with advisors makes it more difficult to co-produce knowledge that is relevant to their needs. In addition, back office activities such as scientific monitoring, building and updating databases and scientific experiments have been restructured in a way which does not support their interests.  相似文献

This paper examines the notion of inclusiveness in rural producer organizations (RPOs) and the extent to which such RPOs can be used to reach the rural poor in sub-Saharan Africa. Using farmer cooperatives in Ethiopia as a case in point, the paper examines the role of RPOs in supporting smallholder commercialization, and the extent to which principles of an inclusive, bottom-up approach relate to their marketing performance. Based on a combination of nationally-representative household- and cooperative-level survey data, we find that poorer farmers tend not to participate in these organizations although they may indirectly benefit from them. When they do participate, they are often excluded from decision-making processes. Finally, we investigate the relationship between marketing performance and inclusiveness and uncover evidence of significant tradeoffs between them.  相似文献

In the 1940 and 1950s, the Rockefeller and Ford Foundations initiated overseas rural and agricultural development activities in a number of countries in Asia and Latin America. They began with country programs. These programs often involved creating new institutions in the recipient countries, and while the perspective was long term – as long as it took to achieve program goals – the foundations also explicitly sought to work themselves out of a job and turn over responsibility to nationals. By 1960 the two foundations had moved beyond national assistance programs to invent a new model, the international agricultural research center, designed to improve the lives of poor rural people by increasing the productivity of developing world agriculture. Some of the national programs were morphed into international centers. The international agricultural research centers proved attractive to other donors and by the 1970s international agricultural research had become institutionalized in the form of the CGIAR and its associate centers. The 1960s India agricultural program of the Rockefeller Foundation comprised a team of about a dozen American scientists working in India assisting Indian scientists to invent new approaches to agricultural technology development. At the same time and also in India, the Ford Foundation pioneered the integrated rural development model. By the mid-1970s integrated rural development projects were the approach of choice for many donors. In the 1980s the Ford Foundation moved away from agriculture concentrating on broader social issues; the Government of India and Rockefeller Foundation decided Foundation scientists had, indeed, worked themselves out of their jobs and Rockefeller’s India program was effectively closed down, although by then the international agricultural research centers, including ICRISAT in India, had attained a degree of maturity and stability. The Rockefeller Foundation invented another new model for agricultural research in the 1990s – the international rice biotechnology network, in which leading scientists from Asian countries, Western countries and the international centers worked together within a framework managed by Rockefeller scientists. In 2006, the Bill Melinda Gates Foundation entered the global agricultural scene in partnership with the Rockefeller Foundation to establish AGRA, yet another new model. By 2010 the Gates Foundation was annually spending about 10 times  相似文献

We examine the decision to prepay a fixed‐rate mortgage in the United Kingdom, Canada, Ireland, Australia and New Zealand. These countries are characterized by having substantial fees which are associated with breaking a fixed‐rate mortgage. We develop a model which allows for fluctuations both in banks’ wholesale rates and credit spreads. We find that households can achieve economically significant benefits both from following an optimal prepayment strategy contingent on the break fee used by their bank and also by selection of fixed interest rate term and (where available) break fee structure.  相似文献

Leadership research in Asia: Taking the road less traveled?   总被引:4,自引:4,他引:0  
Asia is a geographical region with a cultural emphasis on power distance, paternalism, collectivism, and social relations. Leadership in this area plays an important role in organizational processes and outcomes; however, whether this role is similar to that outlined in the mainstream leadership research and non-Asian settings is yet to be confirmed. In this Special Issue on ??Leadership in Asia,?? we selected six papers and identified four emerging themes. First, several mainstream leadership theories are applicable in Asia. On the other hand, we also identified processes and effects that are unique in Asia. Second, leadership in Asia affects organizational outcomes. Third, a strong emphasis on families and social ties among Asian corporations highlights intriguing leadership dynamics in this part of the world. Finally, new context-specific leadership constructs are identified and discussed. In light of these findings, we discuss the future directions of leadership research in Asia.  相似文献

This paper investigates contextual factors which impact on how business lobbying is carried out in radio spectrum policy in the European Union (EU). Based on the empirical evidence collected by means of ten expert interviews, the following considerations are drawn: first, the European Commission (hereafter “the Commission”) weighs highly information provided by corporate stakeholders which is in line with the EU objective to promote EU-wide coordinated use of radio spectrum. Second, the way the Council of the EU (hereafter “the Council”) is lobbied at EU level is unclear because of lack of transparency in the Council. Third, radio spectrum policy issues require niche expertise to be addressed because of high degree of complexity. Fourth, radio spectrum policy issues are characterised by low degree of salience as they are too technical for the wider public. Although centred on the EU context, the issues raised in this study, such as lack of transparency and civil society underrepresentation, are not unique to the EU system. In this respect, comparative studies between the EU and other institutional contexts may contribute to a better understanding of variation in business lobbying.  相似文献

What drives mergers and acquisitions (M&As) in different institutional environments? This article builds on the resource dependence perspective and argues that networks, learning, and institutions represent three building blocks that can enhance our understanding of the drivers behind M&As. Specifically, we consider firms as learning actors embedded in network relations and influenced by institutional development, and compare and contrast firms' acquisition activities across the United States and China. Our findings show that there are indeed important learning and network factors that lead to M&As. More interestingly, the impact of such learning and network factors varies sharply across countries with different market‐based institutions. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

Public e-services are a broad and growing research field in which scholars and practitioners from different domains are involved. However, the increasing attention devoted to public e-services only partially captures the extreme variety of aspects and implications of the diffusion of information and communication technologies at all levels of public administrations. The paper aims to develop a meta-analysis of the literature on the delivery, diffusion, adoption and impact of public e-services and examines differences in methodologies, approaches and key indicators across five service categories: e-government, e-education, e-health, Infomobility and e-procurement. We examined 751 articles appeared in 2000–2010 in the top international academic journals listed in the SSCI-ISI, as classified in the following fields: Communication, Economics, Education, Environmental Studies, Geography, Health Policy and Services, Information Science and Library Science, Law, Management, Planning and Development, Public Administration, Transportation and Urban Studies. We highlight a significant heterogeneity in scientific production across service categories, indicators used, and affiliation of authors. We also show an increasing diffusion of quantitative methods applied to different research fields which still appears to be constrained by data limitations. The overall picture emerging from the analysis is one characterized by largely unexplored domains as well as scarcely analyzed issues both across and within individual service categories. Thus many research opportunities seem to emerge and need to be exploited from different disciplinary perspectives in this field of analysis.  相似文献
