This article provides the first known examination of how animal welfare information provided by media sources impacts beef, pork and poultry demand. Results suggest that media attention to animal welfare has a small, but statistically significant impact on meat demand. Long‐run pork and poultry demand are hampered by increasing media attention whereas beef demand is not directly impacted. Loss in consumer demand is found to come from exiting the meat complex rather than spilling over and enhancing demand of competing meats. An outline of economic implications is provided for the broader discussion of animal welfare.  相似文献

Rising world prices for fuel and food represent a negative terms‐of‐trade shock for Mozambique. The impacts of these price rises are analyzed using various approaches. Detailed price data show that the world price increases are being transmitted to domestic prices. Short‐run net benefit ratio analysis indicates that urban households and households in the southern region are more vulnerable to food price increases. Rural households, particularly in the North and Center, often benefit from being in a net seller position. Longer‐term analysis using a computable general equilibrium (CGE) model of Mozambique indicates that the fuel price shock dominates rising food prices from both macroeconomic and poverty perspectives. Again, negative impacts are larger in urban areas. The importance of agricultural production response in general and export response in particular is highlighted. Policy analysis reveals difficult trade‐offs between short‐run mitigation and long‐run growth. Improved agricultural productivity has powerful positive impacts, but remains difficult to achieve and may not address the immediate impacts of higher prices.  相似文献

In this study, we use the Harbinson Proposal and July Framework to compare a ‘likely’ Doha scenario with a realistic baseline. The novelty of this study is that we focus exclusively on the trade‐led welfare impacts in selected EU member states. The important features of this note are the: (i) usage of the latest Global Trade Analysis Project (version 6) data; (ii) focus on EU25 regions incorporating all major Common Agricultural Policy instruments and reforms; and (iii) inclusion of binding tariff overhangs into the Harbinson tariff reductions. Results show the damping effects of tariff‐binding overhangs on welfare outcomes. This and other factors which limit the gains to liberalisation mean that the EU25 only realises 10% of its long‐run welfare gain potential, as defined by complete liberalisation.  相似文献

Increasing water scarcity combined with an increasing demand for food and water for irrigation call for a careful revision of water use in agriculture. Currently, less than 60% of all the water used for irrigation is effectively used by crops. Based on the new version of the GTAP‐W model we analyze the effect of potential water savings and the welfare implications of improvements in irrigation efficiency worldwide. The results show that a water policy directed to improve irrigation efficiency led to global and regional water savings, but it is not beneficial for all regions. The final effect on regional welfare will depend on the interaction of several different causes. For instance, higher irrigation efficiency changes opportunity costs and reverses comparative advantages, modifying regional trade patterns and welfare. For water‐stressed regions the effects on welfare are mostly positive. For nonwater scarce regions the results are more mixed and mostly negative. The results show that exports of virtual water are not exclusive of water abundant regions.  相似文献

This paper describes the findings of a study that used a multi‐market model to assess the potential impact of improved maize technologies on the welfare of various types of rural and urban households in Kenya. The modelling results indicate that technologies developed for high potential regions are likely to have more profound aggregate impacts on maize production and lead to greater reductions in import demand (if prices are controlled) or maize prices (if maize prices are flexible). Technology adoption in high potential regions is likely to have substantially greater positive impacts on aggregate real incomes, but inferior income distributional outcomes compared to technology adoption in marginal regions.  相似文献

The protection of intellectual property rights (IPR) has been a contentious issue for more than 20 years. Industrialized nations have moved to knowledge‐based economies, and simultaneously, trade barriers have fallen, making intellectual property (IP) vulnerable. Adding to this vulnerability are conflicting international institutional environments, belief systems, and economic realities. The debate over IPR protection has become a significant global trade issue pitting the net‐technology producing “North” against the net‐technology consuming “South.” With this in mind, there has been much debate about the impact of alternative IPR regimes (tight or loose) on the welfare of Southern economies. Policy makers, in both the South and the North, search for arguments to convince recalcitrant Southern countries to follow the Northern model of strict IPR regimes. The South, faced with a dilemma, searches for arguments to justify looser regimes or convince its populace that tighter regimes are in the best interest of the nation. The objective of this research is to add empirical clarity about the welfare impacts of weak IPR on the firm and host country. To this end, we employ a novel methodological design and unique context. The research design is deductive, in that we use the empirical setting of Pioneer‐Argentina, S.A., a seller of bioengineered agricultural seeds, to test the existing theory of weak IPR impacts in a North–South context.  相似文献

Models are constructed to assess the welfare effects for producers, consumers and society of producers using forecast prices based on more accurate estimates of variables causing shifts in the demand for and supply of commodities. The basic model is a stochastic cobweb model in which producers' forecast price is the rational forecast price. The model is extended for many commodities, for partial producer response to more accurate forecast prices, and to include stock holding. In terms of economic surplus, producers and consumers gain from more accurate estimates of demand shift variables, producers gain and consumers lose from more accurate estimates of supply shift variables, and in both cases there is a net society gain.  相似文献

The prolonged drought from 2006–07 to 2008–09 in south‐eastern Australia presented severe difficulties for dry‐land and irrigation farmers in the southern Murray‐Darling basin. A dynamic multi‐regional computable general equilibrium model (TERM‐H2O) is used to estimate the economy‐wide small region impacts during and after drought. Drought reduces real GDP in some small regions by up to 20 per cent. Irrigation water trading and farm factor movements alleviate losses. The drought results in an estimated 6000 jobs being lost across the southern basin. Depressed farm investment during drought results in farm capital not returning to baseline levels after drought. Consequently, job numbers in 2017–18 remain 1500 below forecast in the southern basin.  相似文献

This study estimates the effects of a large discrete maize price increase on the welfare of a sample of rural Kenyan households. The usual first‐order welfare approximation formula is extended to a second‐order formula that allows for supply and demand responses to the price change. Results show that many rural households are not affected greatly by the price change, and there are about as many gainers as losers. However, these full sample results mask important differences across regions. Welfare gains generally take place in major production areas while losses are in areas where most households are net buyers of maize. Semiparametric methods are used to investigate the relationship between income and the size of the welfare effect, and poverty dominance techniques are applied to study the impacts of the maize price increase on rural poverty.  相似文献

The potential for improving irrigation scheduling decisions and adoption of more efficient irrigation systems is explored using a bioeconomic simulation model of lettuce production on the Gnangara Mound near Perth, Western Australia. Sandy soils with poor water and nutrient holding capacity are associated with declining marginal productivity of water at high water use, which would create an incentive to reduce water use and to adopt closer sprinkler spacing if farmers had correct information about the declining marginal productivity of water. Incorrect perceptions regarding water–yield relationships lead to over use of water by up to 50 per cent and reduce profits by 475 per crop hectare (12 per cent) in the short run, and remove the incentive to adopt more efficient systems in the long run. Higher water prices create an incentive to reduce irrigation scheduling time in the short term and to adopt more uniform sprinkler systems, and tend to reduce the discrepancies associated with poor information about the marginal productivity of water. The low level of adoption of efficient irrigation systems in the region might be explained partly by historically poor water governance and insufficient extension regarding water productivity and technology.  相似文献

The development of the wind energy sector is often promoted as a means of supporting rural economies. This paper focuses on how the ownership structure of on‐shore wind power plants (external, farmer or community) affects the size and distribution of impacts within the rural part of a region. Empirical analysis is based on a regional computable general equilibrium model of North East Scotland with the results compared to those generated from a standard social accounting matrix multiplier analysis. With no local ownership, while rural GDP increases, there is almost no effect on household incomes due to the limited direct linkages of the on‐shore wind sector. Local ownership increases the household income benefits but there are still limited positive spill‐over effects on the wider economy unless factor income is re‐invested in local capital. With re‐investment, farm household ownership gives rise to the largest increase in total household income but community ownership gives rise to the largest increase in rural (non‐farm) household incomes and welfare. The results contribute to the on‐going debate about the opportunity cost of external asset ownership in rural areas.  相似文献

The nineties’ agricultural reforms in China that were aimed at deregulating the agricultural market eventually resulted in a huge drop in agricultural production and a high rate of inflation in agricultural input prices; this apparently motivated the government to introduce the grain self‐sufficiency regime in 1998. We examine how and to what extent this reform affected the productivity and welfare of grain farmers in China at the regional level. We find that the price regulations that destroyed the incentive to exert more effort adversely affected the growth in agricultural productivity but contributed to the growth in farmers’ welfare. Although the price regulations resulted in short‐term improvement in welfare across all the regions, in the long run such regulations can potentially result in larger drop in agricultural production because of its negative impact on the incentives to produce more.  相似文献

The visual impact of aquaculture is a controversial issue and in some countries must be assessed prior to any new development. However, at present, there are no definitive, objective methods used to evaluate the potential visual impacts of new aquatic farms and therefore assessment is difficult for both developers and regulators. This study presents a GIS based methodology for use in the visual assessment of a potential new coastal fish farm development, focusing on both sea cages and the associated land based structures. The methodology has been applied to a case study area, the Western Isles located off the North West coast of Scotland, which already has an extensive aquaculture industry and significant potential for future growth.Using a two stage sequential modelling process, the methodology combines visual, seascape and landscape analysis within a GIS environment to produce spatial models indicating where there is the potential for new aquaculture development with minimal visual impact. The preliminary visual assessment model combines a series of Boolean viewsheds with landscape and seascape sensitivity models to assess the potential visibility across different user groups and the sensitivity of the area to visual change. The second stage focuses on an area identified from the preliminary model as having potential for development and then performs a more detailed analysis using a site specific proportional visual impact model. This model quantifies the impact by assessing the proportion of viewpoints from which the proposed development can actually be seen. Both stages of the modelling process provide valuable information and support for decision makers regarding the potential visual impacts of aquaculture.  相似文献

Crop management innovations are often not discrete fixed stand‐alone options—and their adoption may imply various combinations and adaptations. This potentially confounds their impact assessment. This article assesses the resource saving and productivity enhancing impacts of a crop management package revolving around minimum tillage in maize‐based farming systems in northwest Ethiopia. An endogenous switching regression model was applied to plot‐ and household‐level survey data collected from 290 rural households operating 590 maize plots during the 2012 production year. Controlling for variations in plot and household characteristics, the average effect of minimum tillage package (minimum tillage package) on maize productivity is 0.44 t/ha. Compared to conventional practice (CP), adoption of the MTP decreased the average male and female labor use in maize production by 14.4 and 8.2 person‐days per ha, respectively. Similarly, MTP adoption decreased draft power use for land preparation by 13.2 pair of oxen‐days per ha. Compared to CP, in general, there is a considerable short‐run maize productivity gain and reduction in labor and draft power use under MTP.  相似文献

Agricultural intensification by irrigation is increasingly regarded as the key to solving food supply problems in Sub‐Saharan Africa. Conversely, mounting empirical evidence suggests that irrigation externalities might preclude long‐term sustainability of arable agriculture. Choosing between intensive irrigation schemes and less intensive farming systems is therefore, problematic. The paper examines the implications of irrigation intensification in south‐eastern Nigeria using adjacent rain‐fed farms as the counterfactual. The analyses found mixed results. When first introduced, the irrigation scheme increased marginal factor productivity and gross margins but this has subsequently declined to the extent that the marginal factor product of land has become negative. The annual yields of the irrigated farms were also less stable than those of the less intensive rain‐fed farms. These results indicate the dilemma that irrigation externalities present to sustainable agricultural policy and suggest a need to look again at the potential for developments in rain‐fed systems.  相似文献

Irrigation water productivity in Cambodian rice systems   总被引:1,自引:0,他引:1  
Knowledge of the marginal productivity of water is crucial for decisions about its allocation between uses, which is particularly important in the context of increasing competition for water. Using primary, plot‐level panel data, this article estimates the marginal productivity of water from supplementary irrigation in lowland rice systems in Cambodia, taking into account farmer and plot heterogeneity as well as self‐selection of supplementary irrigation. Our estimates indicate a range of elasticities for rice output with respect to water inputs of between 0.057 and 0.069 for wet season production, substantially lower than previous estimates based on either aggregate or trial data. We discuss the policy implications of these results, in particular with respect to the utility of demand management policies and the challenges they pose to the decentralization of water management to Farmer Water Users Groups.  相似文献

Market Imperfections and Land Productivity in the Ethiopian Highlands   总被引:1,自引:0,他引:1  
This study analyses how market imperfections affect land productivity in a degraded low‐potential cereal‐livestock economy in the Ethiopian highlands. A wide array of variables is used to control for land quality in the analysis. Results of three different selection models were compared with least squares models using the HC3 heteroskedasticity‐consistent covariance matrix estimator. Market imperfections in labour and land markets were found to affect land productivity. Land productivity was positively correlated with household male and female labour force per unit of land. Female‐headed households achieved much lower land productivity than male‐headed households. Old age of household heads was also correlated with lower land productivity. Imperfections in the rental market for oxen appeared to cause overstocking of oxen by some households. Conservation technologies had no significant positive short‐run effect on land productivity. The main results were consistent across the different econometric models.  相似文献

Option values may be an important component of non‐use values when development options for environmental assets are considered. These are values that the community might hold for maintaining options to make future choices about allocating resources. However, option values are very difficult to define, at both theoretical and practical levels, and there has been a retreat over the past decade to the more inclusive concept of option prices. In the present paper, estimates of option values are reported for retaining unallocated water in reserve rather than using it for current development. The use of option values rather than option prices is justified on the basis that the focus is on non‐use values, and demand and supply uncertainties have been minimised. These values have been assessed through a series of nine choice modelling surveys that have been conducted over a 3‐year period in the Fitzroy River Basin in central Queensland. The results are then extrapolated to the case study areas within the basin to assess whether unallocated water should be held in reserve or used for development.  相似文献

Queensland experienced extraordinary growth in booked 2P coal seam gas (CSG) reserves, rising from 3,400 PJ in 2005 to 41,200 PJ in 2013. Given annual domestic consumption of ca. 700 PJ/a, 2P reserves rapidly shifted from 14 to 72 years supply. Profit‐maximising firms sought to speed up commercialisation of reserves through the development of three liquefied natural gas (LNG) export plants at Gladstone. In this article, we present forecasts of Australia's east coast interconnected gas system with daily resolution using our dynamic partial equilibrium model. Modelling results show the rapid development of LNG plants combined with restrictive CSG development policies in NSW may result in unserved load from 2016. Relaxing development constraints or delaying construction of one LNG terminal by 1 year could have avoided the risk of Unserved Load events in the domestic gas market. Lessons can be learned from this CSG‐LNG boom scenario. Facilitating new gas supplies is the most efficient way of alleviating the impacts of the CSG‐LNG boom on domestic markets in the medium term. In the long‐term, Australian policymakers may consider the merits of a National Net Benefits Test to maximise welfare through appropriate coordination – as is done by policymakers in the USA – as opposed to protecting local industries through ‘domestic gas reservation policies’.  相似文献

Hubbard and Philippidis Journal of Agricultural Economics (2001) Vol. 52, pp. 87–95] employ the standard Global Trade Analysis Project (GTAP) computable general equilibrium (CGE) model to analyse the impact of the bovine spongiform encephalopathy (BSE)‐induced ban on exports of UK beef. This note extends that study in four ways: (i) the dynamic GTAP model is employed to characterise long‐run savings–investment behaviour more correctly; (ii) the effect of the foot‐and‐mouth disease (FMD) outbreak of 2001 is included; (iii) an allowance is made for different levels of recovery in consumer confidence; and (iv) the impact analysis is now compared through time with a ‘no‐ban’ baseline. Long‐run comparisons after removal of the ban suggest that its legacy may continue for some time. However, because of the remedial safeguards and assurances offered in the wake of the BSE and FMD crises, there is a possibility that exports and outputs increase. Nevertheless, the economy‐wide impacts are negligible in both the short and the long run.  相似文献
