Site selection to test an integrated approach to agricultural research for development: combining expert knowledge and participatory Geographic Information System methods

The sub-Saharan Africa challenge programme is designed to address the problems of failures of agricultural markets, inappropriate policies and natural resource degradation, that contribute to the continuing deterioration of livelihoods and food security in the region. It is seeking to do this by redefining the roles of scientists and farmers through collaborative learning processes, addressing questions about the level, timing, type and formof participation, as well as themost effective approaches andmethods to foster them. The research domains of the programme deal with sustainable intensification of smallholder agriculture, the sustainable management of natural resources, the development of efficient markets, and the promotion of enabling policies. One question that was addressed in designing the initiative was deciding where to work so as to maximize the chances of successful testing of this new approach, so that it would lead to significant reductions of rural poverty. A participatory process was put in place to design a framework to accomplish this site selection, and then to apply it in west, east and southern Africa. A mixture of spatial data analysis and expert knowledge on spatial and non-spatial factors was used, and one primary site in each region was identified to form the basis for the next phase of the challenge programme. Several lessons were learnt from the process, including the importance of adapting themethods to actual conditions, the increased utility of targetting when the quantitative and the qualitative are freely combined, and the continued need for baseline spatial and non-spatial data to improve the targeting of research in the future that is designed to alleviate poverty in sub-Saharan Africa.     

A Natural Resource Scarcity Typology: Theoretical Foundations and Strategic Implications for Supply Chain Management

World population growth and increased consumption stemming from economic leveling are leading to scarcity of a number of natural resources on a global scale. Scarcity of critical natural resources such as oil, water, food, and precious metals has the potential to greatly impact commercial activity as the twenty‐first century progresses. The challenge of continuing to provide needed goods and services in the face of these constraints falls to supply chain managers, who are ultimately responsible for delivering utility to customers. Unfortunately, there has been almost no research focused on supply chain strategies aimed at mitigating natural resource scarcity’s (NRS) potential effects. The current research positions NRS as a supply chain risk and proposes an NRS typology based on key resource attributes. Supply chain mitigation strategies to counter each resource status are offered, with an overall objective of improving supply chain performance. The study recommends future research aimed at further developing theory and methods for countering NRS based on resource, systems and behavioral theories. In addition, this study has critical implications for practitioners faced with the growing threat of NRS in their supply chains.     

Costs of Accounting to Lenders: Canadian Evidence

Do new accounting pronouncements impose costs on firms with accounting-based restrictions in their public lending agreements? Previous studies have not found significant, adverse share price reactions to such pronouncements. This paper posits that management is concerned with the total costs of the monitoring policies used for reporting to lenders, and that share price reactions are likely to comprise only a small portion of those costs. The episode of mandatory lease capitalisation in Canada is used to test some predictions that are consistent with this expanded view of the costs of accounting to lenders. Lessees ‘public lending agreements were examined to see if they stipulated restrictions based on accounting numbers; and, if they did, whether the constraints were based on GAAP (generally accepted accounting principles) or TAP (tailored accounting principles). The evidence strongly supports the hypothesis that there are costs of accounting to lenders; but these costs are unlikely to be observed by researchers who look only for adverse share price reactions to mandated accounting changes. It also indicates that Canadian standards setters were sensitive to lessees’ accounting costs.     

Household‐level Impacts of Dairy Cow Ownership in Coastal Kenya

This study uses heteroskedastic Tobit and Censored Least Absolute Deviations models to examine the impacts of dairy cow ownership on selected outcomes for a sample of 184 households in coastal Kenya. The outcomes examined include gross household cash income, gross non‐agricultural income, consumption of dairy products, time allocated to cattle‐related tasks, number of labourers hired and total wage payments to hired labourers. The number of dairy cows owned has a large and statistically significant impact on household cash income; each cow owned increased income by at least 53% of the mean total income of households without dairy cows. Dairy cow ownership also increases consumption of dairy products by 1.0 litre per week, even though most of the increase in milk production is sold. The number of dairy cows has no significant effect on total labour for cattle‐related tasks. However, in contrast to previous studies, labour allocation to cattle by household members decreases and labour requirements for dairy cows are met primarily by an increase in hired labour. Dairy cow ownership results in relatively modest increases in payments to hired labourers and the number of hired labourers employed. The large positive impacts on income and the substitution of hired for household labour in cattle care suggest that intensification of smallholder dairying can be beneficial as a development strategy in the region if disease and feed constraints are addressed.     

A PEOPLE'S POLICE FOR THE TWENTY-FIRST CENTURY: A REPLY TO BLUNDELL

John Blundell's ideas for structural change could undermine the strengths of British policing. Nevertheless, there is a need for decentralisation and more local control.     

Discount rate changes and the foreign exchange market

Changes in the discount rate can have associated announcement effects on the foreign exchange value of the dollar only if these changes are not anticipated by the market. This paper provides evidence to support this contention. Specifically, discount rate changes made for reasons other than technical adjustments have not been anticipated fully and, consequently, their announcements have had a significant impact on the dollar's exchange rate. Furthermore, results are obtained that support the hypothesis that unanticipated discount rate changes alter inflationary expectations.     

The Licensing of Barbers in the USA

Barbering is one of the earliest professions to be licensed in the USA. This article discusses the origins of barber licensing, as well as its current status and scope, and then estimates the effects that such licensing has had on barbers' earnings. To estimate these effects we use micro‐level data from the 2000 US Census along with several measures of the strictness of state licensing of barbers. Our results suggest that certain licensing provisions may have increased barber earnings by between 11 and 22 per cent. The magnitude of our estimates is somewhat higher than those found in studies examining the effects of licensing in similar professions.
