Does access to off-farm income complement or compete with agricultural production? This article explores the effect of off-farm income on agricultural production activities, using data from the 2003 Mexico National Rural Household Survey. We first discuss the theoretical conditions under which access to off-farm income may influence production in an agricultural household model. Instrumental-variable (IV) estimation methods are then used to test whether agricultural production activities, technologies, and input use differ between households with and without access to off-farm income. We find that off-farm income has a negative effect on agricultural output and the use of family labor on the farm, but a positive impact on the demand for purchased inputs. There is also a slight efficiency gain in households with access to off-farm income. Findings offer insights into how household production evolves as rural households increasingly engage in off-farm income activities.  相似文献

This study provides a review of the literature on sporting production functions with an emphasis on different input‐output specifications and alternative estimation procedures. Empirical evidence is reported for English association football on the robustness of estimates of coaching efficiency to changes in estimation methods and the definition of team performance and playing talent inputs. A measure of player quality based on predicted start‐of‐season transfer values is developed. It is found that the estimation of coaching efficiency is sensitive to the choice of time‐invariant efficiency models versus time‐varying and inefficiency effects models. It is also found that the results are little affected by different measures of team performance but are highly sensitive to the use of an ex post financial expenditure input measure. Ex ante input measures based on start‐of‐season player characteristics or predicted transfer values are recommended as more appropriate on both theoretical and empirical grounds.  相似文献

Our two-equation model of retail promotion provides a well-balanced explanation of both retailers' perceptions of promotion tools and their budget allocation across the promotion mix. While previous studies have examined each of these two components separately, few have integrated both in the one study. Factor analysis was used to simplify the choices of promotion tools. This reduced the number of promotion tools to four, namely mass media, in-store promotion, sales promotion/direct mail and personal selling. We support earlier studies which link budget promotion mix spending (behaviour) to perceptions about the effectiveness of each medium (attitude). The range of determinants of perceptions has been extended by incorporating the roles of retail strategy, store ownership, culture and promotion intensity. We have estimated the budget promotion mix equation using a production function theoretical framework. Although this makes little difference to the strong relationship between retailers' perceptions of promotion tools and budget allocations, the theoretical framework does enable formal estimation of cross-media substitution. We find that the two short-term oriented promotion media are substitutes. Our model has been applied to apparel retailing in Australia, with considerable scope for applications to other retail categories and to other countries.  相似文献

Biotechnology is causing dramatic changes in the seed industry on a national and global level. Further, the delivery of technology through seed is affecting all aspects of crop production. Coined the Third Wave of Development, it is a drive to meet specific end use traits through biotechnology. In light of this, the industry is seeing increased integration between all those involved in the chain of production. Adapting to this new environment creates significant challenges for the industry, including regulatory, international, handling, and structural.
As the Canadian seed industry changes dramatically to meet the specific needs of end users, there has been an increase in strategic alliances between both handling and seed companies to accommodate identity preserved production. There has also been an increase in mergers and acquisitions, as R&D companies attempt to marry novel trait developments with good germplasm and seed production expertise.
Yet, this is only the beginning as the integration of the seed industry with other aspects of the crop inputs sector applies even more pressure to integrate the agri-food industry right from plant breeding through to end use.  相似文献

We seek to understand the ever-increasing push towards the international harmonization of accounting standards and particularly the inexorable rise of standards produced by the International Accounting Standards Board (IASB). While the primary justifications for the increasing recognition given to these standards (IFRS) are economic, we question whether the empirical evidence to date has yielded convincing support for these arguments. We therefore offer an alternative explanation for the origin and diffusion of IFRS that incorporates social and political factors. Outsourcing the manufacture of accounting standards to a single private agency appears to be a rational, lower cost option – lowering both economic and political costs for individual states as long as they continue to retain residual decision rights with respect to the adoption of IFRS. However, such outsourcing must also be perceived to be legitimate. IFRS confer institutionalized legitimacy because they possess three characteristics required of a technology for global governance. These are sponsorship by powerful interest groups/regulators, internationality and plasticity. We therefore conclude that the widespread diffusion today of IFRS can at best be only partially explained as an economically rational phenomenon. Rather, the demand for legitimate action in the face of tightly coupled and complex global markets is at least equally important in generating support for IFRS.  相似文献

In this exploratory study of union formation in the Indian call centre/business process outsourcing sector, the authors draw upon evidence from the first detailed survey of members of the recently formed UNITES, and from extensive interviews. This paper engages with mobilisation theory and analyses of trade union formation.  相似文献

【美国《市场观察》5月16日】在未来几年之中,通胀问题以及应对之策都将是亚洲面临的中心政策议题。今后几个季度,外需对亚洲经济增长的推动作用将逐渐减弱。在这种情况下,迅速攀升的通胀率势必会加剧政治压力,并影响亚洲向内需导向型经济增长的平稳转变。进入2008年之时,注重经济增长的亚洲决策者曾希望通过降息来刺激内需,以便弥补外需的损失。而今,他们非但不能降息,而且还可能要被迫加息。  相似文献
