Estimating the Price Elasticity of Demand for Water with Quasi Experimental Methods

There is a growing recognition in both the professional and popular literatures that water scarcity is a key policy issue that is especially important in arid, urban settings with the prospects for shortfalls in water availability due to the effects of climate change. Those evaluating these types of water problems usually conclude prices must be reformed so that incentives facing water users change to reflect this scarcity. Demand functions provide the basic economic relationships required to understand how water use will respond to such changes. This paper proposes a new method for estimating the price elasticity of demand that meets policy needs and can accommodate the presence of increasing block pricing structures.Water Demand Elasticity, Quasi Experiment, Climate Change, Consumer/Household Economics, Demand and Price Analysis, Environmental Economics and Policy, Resource /Energy Economics and Policy,

Designing whole-systems commissioning: lessons from the English experience

The paucity of formal evidence, allied to the requirement for strategies that are sensitive to local history and context, means that a ‘blueprint’ for successful strategic commissioning is not currently available for adoption. We are therefore confined to proposing ‘design principles’ for those seeking to embark upon a transition towards a whole systems approach to strategic commissioning. People and relationships are of critical importance all the way through the chain from strategic commissioning to micro-commissioning. Most crucially, experience suggests that structural solutions alone cannot deliver effective relationships and will not be effective when relationships are neglected. The need to ensure staff, partner and political buy-in suggests that relationship management and consensus-building are an integral component of the leadership role in moving toward strategic commissioning. As with any major re-organisation, the move to strategic commissioning is essentially a change management initiative and therefore will stand or fall according to whether it adheres to good practice in the change management process. Central to this, and to achieving commissioning outcomes, is the requirement for meaningful service user and public engagement. Effective commissioning emphasizes individual capabilities as well as needs, and community assets as well as deficits and problems. Adoption of strategic commissioning approaches is still at the developmental and learning stage and arguably all structural arrangements should be regarded as transitional

Enhancement of pigmeat quality by altering pre-slaughter management

End of project reportThe studies presented in this report were conducted to investigate the effect of breed, slaughter weight, castration of male pigs and strategic feeding strategies on the performance of pigs to slaughter and on their carcass quality. The effect of breed, gender and feeding regimen on the performance of pigs and their carcass quality was examined in the first study (Section 3). From weaning to slaughter Landrace-sired pigs grew at a similar rate but had a better feed conversion efficiency compared with Duroc-sired pigs. Landrace-sired pigs also had a higher carcass lean and greater muscle depth than Duroc-sired pigs. Entire male pigs grew more efficiently, had lower lean content in their carcasses and had a reduced kill out yield when compared with gilts. The eye muscle depth was greater for gilts than entire males. Diluting the diet with grass-meal (GM) reduced growth rate, caused a deterioration in feed conversion efficiency, reduced back fat thickness, reduced eye muscle thickness and reduced kill out yield compared to the control feeding regimen of a cereal based diet. Compensatory growth was observed during a re-alimentation period following a period of diet dilution with grass-meal. However, where it did occur, in most cases it was only partial. Adding 5% rapeseed oil instead of lard to the finisher diet increased nitrogen utilization efficiency and phosphorous utilization efficiency. The effect of gender (boar, castrate, gilt) and slaughter weight (80 to 120kg) on pig performance, carcass quality, meat quality, and nitrogen excretion was investigated in the second study (Section 4). Boars grew faster than gilts and more efficiently than castrates or gilts. Castrates had a higher kill out yield than boars. Nitrogen excretion from castrates was similar to gilts which were both higher than that from boars. The processing value of carcasses from castrates may be higher than that of boars and gilts. In particular castrates had heavier loins and bellies than either boars or gilts. Carcasses from castrates and gilts had a higher temperature (recorded 24 hours post slaughter) than boars. However, pH24 was not affected by gender. The intramuscular fat content of the l. dorsi in castrates was higher than that of boars or gilts, however at 1.65% this was well below the level (2.0%) above which any noticeable sensory attributes might be detected. Feed intake increased with increasing slaughter weight and feed conversion efficiency deteriorated. N excretion also increased with each increment in weight. Carcass lean content increased up to 90kg live EOP 4939.doc 4 25/10/2005 weight then reached a plateau and declined after 110kg live weight. Heavier carcasses yielded more product for approximately the same slaughtering cost and the associated larger muscles could make it easier to use seam butchery techniques that result in lean, well-trimmed, attractive cuts and joints. The pH45 and pH24 were reduced with increasing slaughter weight and drip loss increased. Heavier pigs may be more prone to the development of PSE than lighter pigs as their carcass temperature remains higher for longer than that of lighter pigs
