Enhancing farmers’ capacity for botanical pesticide innovation through video-mediated learning in Bangladesh

Despite the general success of farmer-capacity-building methods such as Farmer Field School in promoting pest management innovations, only those farmers directly involved benefit. How can agricultural extension enable farmer-to-farmer learning about botanical pesticides beyond such schools? We wanted to know how different learning methods, such as video shows and workshops, change farmers’ knowledge, attitudes and practices about botanical pesticides. This paper explains how video engages men and women farmers in spreading botanical pesticides across 12 villages in Bogra District, north-western Bangladesh. We conducted ex ante and ex post surveys among farmers from November 2009 to September 2010. For data analysis, we used t-test and McNemer and Wilcoxon sign rank tests. Our findings suggest that video improves the ability of both male and female farmers to communicate about pest management among themselves and with other stakeholders, as ‘intricate ethno-agricultural practices’. Video-mediated learning sessions are more effective than conventional workshop training in enhancing farmers’ knowledge about botanical pesticides, changing their attitude and finally taking a decision to adopt these methods. In other words, video is capable of communicating complex issues such as the biological and physical processes that underlie pest management innovations. From our case, we conclude that agricultural extension is more effective with the use of facilitated video learning and that this process clarifies complex agro-ecological principles, bias and normative perceptions of the learners. Also, video-mediated learning is not only transferable across villages, but also works well in combination with other media, such as radio, television and mobile phones.     

In the quest for their trust: the perceptions of families on accessing leisure services for disabled children

This paper is based on the findings of a research project commissioned by a public body in the English Midlands, UK. Telephone surveys, focus groups and individual interviews were the data collection methods. It focuses on the perceptions of 44 families on the barriers to accessing leisure services for disabled children. Although there are numerous advantages for accessing such services, the findings showed that the families had very few successful experiences with the current provision due to a number of structural barriers. Trust was perceived as crucial to access these services.     

Paying for performance: Efficiency wages and mutuality

The motivation of individuals lies at the core of corporate governance. For CEOs much research has been directed at the linkage between pay and enterprise performance. The results, however, provide only weak support for the efficacy of profit-related pay. Herein we adopt a different perspective and test for the existence of efficiency wages in a mutual sector wherein the use of traditional control mechanisms is particularly problematic. Our empirical results support the hypothesis that efficiency wages do yield superior performance. We therefore conclude that efficiency wages are a much-needed tool of corporate governance in the mutual sector. Furthermore, as an incentive mechanism, efficiency wages do not require the observability of individual effort, thus they potentially provide an equitable incentive mechanism for all organizations.     

Efficiency in nuclear power pricing

This study investigates whether the rate structure for electric utilities with nuclear and fossil fuel generation is efficient and perhaps equitable. Data were collected on fossil and nuclear steam generation and transmission to estimate costs. Tests were performed to determine if efficient pricing practices were being followed. The results indicate that the marginal cost of nuclear generated power is less than that of power generated from fossil fuel sources. Also, the rate structure for the nuclear utilities is inefficient, with industrial rates significantly higher than first-best or second-best pricing criteria would indicate.     

Does endogenous formation of jurisdictions lead to wealth-stratification?

Conditions under which endogenous processes of jurisdiction formation entail wealth-stratification are examined in a model where unequally wealthy households with identical preferences form jurisdictions in order to produce a public good financed by proportional taxation. We define a stable jurisdiction structure to be a partition of the households into jurisdictions that is immune to individual deviations. We define a jurisdiction structure to be wealth-stratified when each jurisdiction is composed of households who form an interval with respect to the ordering of their wealth. We show that a necessary and sufficient condition for the stratification of any stable jurisdiction structure is for the individual preferences for the public and the private good to exhibit a relation of gross substitutability/complementarity between the public good and the private good that is independent from prices and wealth.     

Wholly-owned vs. collaborative ventures for diversifying financial services

Recent empirical work has supported the Penrose-Teece view that firms diversify to exploit fully specific assets or capabilities. Where transactions costs permit, these economies of scope may be realized via input supply contracts among producers. However, asset specificities frequently create transactions costs which discourage market contracting and leave firms with a choice between collaborative ventures and wholly-owned new entry. This research uses the natural experiment of financial services deregulation to explore the collaborative-own entry choice for 292 new entries in 13 financial product markets. The results generally support our maintained hypotheses that specificity encourages full ownership while collaboration is used to ease a resource constraint.     

Free trade and income redistribution in some developing and newly industrialized countries

A competitive general equilibrium model of production is specified and the long-run comparative static elasticities of changing prices on factor prices are examined in eight developing and newly industrialized countries. Unskilled labor in these developing countries stands to gain from a program of global free trade characterized by increased manufacturing exports and falling prices of imported business services, while capital owners and skilled labor lose. Results are contrasted with developed countries, the United States in particular, where unskilled labor will lose while capital and skilled labor enjoy gains with global free trade.
