Co-operation in Risky Environments: Evidence from Southern Ethiopia

The semi-arid and arid rangelands of Sub-Saharan Africa arecharacterised by high variability and by heavy reliance of herderson access to common resources, predominantly pasture and water.In these systems, the capacity of the community to co-operateover resource management is critical and the effectiveness ofmanagement has a direct impact on exploitation rates and landallocation patterns. In this paper, we develop a model to capturethe impact of climatic variability on capacity to co-operateand on resulting land use and allocation patterns, and applythe model to data collected from communities located on theBorana Plateau in southern Ethiopia. Results indicate that rainfallvariability has a negative impact on stock densities, consistentwith risk-averse producer behaviour, but has no statisticallysignificant impact on land allocation patterns in this marginalarea. Furthermore, co-operation has a direct negative impacton stock densities and land allocated to private pastures. Theresults support the hypothesis that individual incentives toovergraze and encroach on common pastures can be mitigated incommunities with high co-operative capacity.     

The Private Finance Initiative: Has the Accounting Standards Board Reduced the Scheme's Value for Money?

This article examines the state of PFI in the UK following an amendment published by the ASB to FRS 5. It was predicted that this amendment would mean that most properties constructed by the private sector, on behalf of the public sector, would have suddenly to appear on the balance sheets of the latter. This would have led to an unacceptable level of public sector borrowing and could have undermined the entire rationale for the scheme. Having outlined the objectives of PFI and explained the attitude adopted by the ASB, the article examines the reaction of HM Treasury. The article then demonstrates the likely consequences of the main parties in PFI contracts passing on as much risk as possible to the private sector so as to ensure that the assets remain off balance sheet. It concludes by assessing the expected impact that these actions will have on value for money.     

Limits to Ecological Modernisation as a framework for sustainable fresh water governance

An important point of debate in contemporary environmental governance literature is the design of institutional arrangements for natural resource governance in Western democracies in the face of long-term ecological challenges. Informed by this debate, we ask in this paper to what extent does Ecological Modernisation precepts provide a governance framework for resolving freshwater management conflicts in the context of New Zealand's political economy? The paper draws on the region of Canterbury whose water resources have become the site of intense political conflict due to the rapid growth of dairy farming. We firstly argue how the precepts of Ecological Modernisation are promoted in natural resource governance through the discourses of a variety of stakeholders at both the national and regional level and secondly, demonstrate how the adoption of these precepts in institutional design reflect a broadly techno-corporatist interpretation of Ecological Modernisation theory which struggles to sustain ecological carrying capacity of freshwater resources.     

The effect of the human pheromone androstenol on product evaluation

The chemical communication between humans has received considerable attention recently. Among the findings in psychology and anthropology have been the effects of putative human pheromones on the evaluation of persons. This article investigates if the finding that the pheromone androstenol influences person evaluation extends to the evaluation of products. In a laboratory experiment, 120 participants randomly assigned to either an experimental or control group rated three magazines. It was found that male consumers evaluate male magazines as more masculine and more positively under the influence of the putative male pheromone androstenol, whereas no such effects were found for magazines rated neutral or feminine and with respect to female consumers. Possible contextual and other factors influencing these results are discussed. © 2005 Wiley Periodicals, Inc.     

Sustainable development,the Hartwick rule and optimal growth

Defining sustainable development as non-declining utility, the consistency of this concept with the Hartwick rule and optimal growth is explored when resources are exhaustible. A simple proof that a generalized Hartwick rule is necessary and sufficient for constant consumption is derived. The existence of a maximal constant consumption path is shown to depend critically on the elasticity of substitution; if this is less than 1, consumption declines; if it is greater than 1 then consumption is not maximal; if it is equal to 1 (the Cobb-Douglas case) then existence is proved. Consumption can increase along an optimal path if the pure rate of time preference is 0; if it is non-zero then consumption declines.     

The Salzburg sound of management

To many, Salzburg is correctly identified with Mozart and music festivals. To an increasing number of Europeans, it is also the scene of an exciting experiment in management education.     

Measures of appropriateness: the resource requirements of anaerobic digestion (biogas) systems

Anaerobic digesters have a potential for providing fuel, fertilizer, and a sanitary means of waste disposal in rural areas of less developed countries. Despite these potential benefits, digesters have had a disappointingly low success rate in many LDCs. Poor economics may explain these failures in some cases but poor fits between digesters and local conditions - a lack of appropriateness - can also be a useful indicator.Using a detailed accounting framework, we disaggregate anaerobic digestion systems into five subsystems, analogous to the subsystem components of the nuclear power fuel cycle. Relying on published information from India and China, we compare 38 fixed-and floating-dome digester models and note qualitative and quantitative differences in their uses of construction and operating resources. Environmental and social resources used in the subsystems are also discussed. A tentative ‘specifications plate’ for anaerobic digestion systems is proposed. This provides quantitative measures of the appropriateness of particular systems in different settings.     

Memory, transaction records, and The Wealth of Nations

Adam Smith hypothesized that impersonal exchange was necessary for a society to develop specialized division of labor and create wealth. Douglass North and Vernon Smith argue that successful developed economies are the result of institutions. We hypothesize and provide evidence from ethnographic data that the basic accounting technology of recording transactions is associated with more extensive impersonal exchange and increased specialization in the division of labor. Our intuition is that extensive impersonal exchange requires reliable memory of trading partners’ past behavior to sustain trust and encourage reciprocity when a group expands beyond the size of traditional hunter-gatherer groups. Our findings are consistent with the hypothesis that transaction records are necessary for the emergence of complex economies as suggested by the archaeological evidence of recordkeeping in Mesopotamian societies 10,000 years ago.
