Dynamics of smallholder participation in horticultural export chains: evidence from Ecuador 下载免费PDF全文
We study the dynamics of smallholder participation in export value chains focusing on the example of small‐scale broccoli producers in the highlands of Ecuador. Combining cross‐sectional data from a household survey with 11‐year longitudinal data on export market transactions, we explain the hazards of dropping out of a high‐value export chain. We apply a multispell cox duration model that allows us to consider multiple entries and exits from the supply chain. We also provide evidence on the welfare impacts associated with participation. The results suggest that small‐scale farmers’ exit from the export sector is accelerated by high transaction risks experienced in the past. While we find no particular evidence for the exclusion of small‐scale farmers from the export sector, we do find that poorer households and female‐headed households tend to drop out faster, especially as long as the sector is still prospering. Finally, when considering welfare effects, we do not find evidence that participation translates into tangible benefits for broccoli farmers. We discuss some measures that could help improve the long‐term sustainability of smallholder integration in high‐value chains. 相似文献

This paper is on the role that the phone plays in a mixed-methods empirical research. In the current sociological literature, the phone is a methodological object associated with quantitative fieldwork, while little is said on the phone as a tool for qualitative research. We reflect here on a case study on the use of parental leaves by fathers in Spain, which included the phone as the only communication tool between researchers and subjects. We collect out own experience as interviewers in the qualitative phase of the research project, and interviewed surveyors working in the field. We analyze the discursive data following grounded theory principles and compare the use of both techniques in the data gathering process, including sampling and design. Thus, we consider interviewing and surveying as mediated communication situations. Our findings show that the value of the phone as a tool for research is a matter of adequacy to a given methodology, rather than an issue of validity, reliability, or credibility. 相似文献

Multinational corporations in the extractive sector have historically faced challenges to their property rights, particularly in oil. International business scholars argue that firms can decrease these challenges by approaching domestic legitimating actors or seeking home government support. Through a study of the operations of Standard Oil of New Jersey in Peru and Argentina in the twentieth century, we find that these legitimating strategies can backfire due to two main elements: first, the multinational might approach actors with a different agenda from those defining, delineating, and enforcing property rights. Second, host countries can use home government support to multinationals to delegitimise foreign firms' operations. 相似文献

This paper presents a novel approach for dealing with risk in agricultural resource allocation decisions by synthesising the conventional Markowitzean, or MOTAD, methods within a compromise programming model to generate ‘best-compromise’ solutions which come closest to an ideal point defined in terms of risk minimisation. This approach can be regarded as the compromise-risk programming model. The purpose here is to show how this ‘hybridisation’ of Markowitz/MOTAD and compromise programming approaches overcomes some of the weaknesses of the traditional approach to handling risk in resource allocation models. 相似文献

Open source software (OSS) is being considered the new paradigm of software distribution. As contrasted with the traditional software marketing model, OSS pursues the freedom to have access to open source and offers several advantages to enterprises. These advantages include saving costs related to Information Systems and Technologies (IS/IT) and the possibility of adapting to changing organizational requirements. However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields. Having considered this obstacle, the authors have defined a foreseeable setting for OSS diffusion and adoption by means of a forecasting study based on the Delphi method for the year 2010. The findings reveal the levels of OSS diffusion for this year according to the main applications, geographic regions and industries. In a complementary manner, the authors have studied the elements of success as well as the most relevant obstacles for diffusing and adopting technological solutions based on OSS. 相似文献
