The introduction of value-based marketing has provided the industry with the means to price cattle based on their desired attributes and has provided an alternative marketing channel for producers to select. Gains can be made by selecting animals that will be "in the grid" for value-based marketing channels while screening out animals that won't and sending them to dressed-value or live-weight marketing channels. This study estimates the gains from using real-time ultrasound (RTU) as well as information on graded animal relations (i.e., animals that have the same parentage slaughtered and graded in previous years) to predict carcass quality and yield grades prior to slaughter. These predictions are used in an optimization model designed to select the marketing channel for individual animals that will maximize returns. The optimal marketing strategy from this study involves a mix of live-weight, dressed-weight and grid sales methods rather than marketing all of the animals together. The results suggest that increases in returns in the range of $0.61–27.26 per head from using relations data, $9.04-16.75 per head from using RTU measures and $11.27-27.93 per head from using both to selectively market beef animals. These estimates do not account for the gains that could be obtained from using RTU to improve market timing, i.e., to time when the animal will grade best.  相似文献

Growing demand for agricultural produce, coupled with ambitious targets for greenhouse gas emissions reduction present the scientific, policy and agricultural sectors with a substantial mitigation challenge. Identification and implementation of suitable mitigation measures is driven by both the measures’ effectiveness and cost of implementation. Marginal abatement cost curves (MACCs) provide a simple graphical representation of the abatement potential and cost-effectiveness of mitigation measures to aid policy decision-making. Accounting for heterogeneity in farm conditions and subsequent abatement potentials in mitigation policy is problematic, and may be aided by the development of tailored MACCs. Robust MACC development is currently lacking for mitigation measures appropriate to sheep systems. This study constructed farm-specific MACCs for a lowland, upland and hill sheep farm in the UK. The stand-alone mitigation potential of six measures was modelled, against real farm baselines, according to assumed impacts on emissions and productivity. The MACCs revealed the potential for negative cost emissions’ abatement in the sheep industry. Improving ewe nutrition to increase lamb survival offered considerable abatement potential at a negative cost to the farmers across all farms while, lambing as yearlings offered negative cost abatement potential on lowland and upland farms. The results broadly advocate maximising lamb output from existing inputs on all farm categories, and highlight the importance of productivity and efficiency as influential drivers of emissions abatement in the sector. The abatement potentials and marginal costs of other measures (e.g. reducing mineral fertiliser use and selecting pasture plants bred to minimise dietary nitrogen losses) varied between farms, and this heterogeneity was more frequently attributable to differences in individual farm management than land classification. This has important implications for the high level policy sector as no two farms are likely to benefit from a generic one size fits all approach to mitigation. The construction of further case-study farm MACCs under varying farm conditions is required to define the biophysical and management conditions that each measure is most suited to, generating a more tailored set of sector-specific mitigation parameters.  相似文献

Determining farmers’ real demand for crop insurance is difficult, especially in developing countries, where there is a lack of formal financial sector integration and a high reliance on informal risk mitigation options. We provide some new estimates of farmers’ willingness‐to‐pay for insurance in the context of a large‐scale subsidised programme in India. We conducted a discrete choice experiment with agricultural households across four states in India, enabling us to estimate preferences for specific insurance policy attributes such as coverage period, method of loss assessment, timing of indemnity payments and the cost of insurance. Our results suggest that farmers do value crop insurance under certain conditions and some are willing to pay a premium for such coverage in excess of the subsidised rates they are currently required to pay under this programme. In particular, farmers value the assurances that they will receive timely payouts when they incur losses, and may not have a strong preference for the method with which losses are assessed. On the other hand, farmers are quite sensitive to coverage periods. Our baseline assessment shows that when optimised to farmer requirements, there can be a sizeable demand for crop insurance by developing country farmers.  相似文献

What is the optimum slaughter weight? It depends from whose perspective. A dynamic systems model is built to analyze the welfare impact of alternative animal genetics, feeding program, feed quality and slaughter weight on producers, processors and the environment. The unique systems approach analyzes eight possible welfare rules and a corresponding harm function to assess animal performance within a multistakeholder context. The model results show there are significant tradeoff problems among producers, processors and the environment. The model highlights how the definition of animal performance needs to be revisited, as it has different meaning to different stakeholders in society. While performance historically was synonymous with production efficiency, with new social and political concerns, this interpretation is not universal. The model demonstrates greater complexities by broadening the set of affected parties.  相似文献

The effect of carcass quality uncertainty on the structure of the slaughter cattle market is investigated. A theoretical extension of the “Theory of Factor Price Disparity” is provided. It is demonstrated that the coexistence of a risk premium wedge between marketing channel (live weight, dressed weight, and grid) pricing mechanisms, in conjunction with varying degrees of producer risk aversion or producer perception of carcass quality uncertainty, contributes to the coexistence of multiple marketing channels. It is also demonstrated that risk and risk preference provide the linkage between carcass quality uncertainty and producer marketing decisions. We demonstrate how this linkage can affect the structure of the fed cattle market and the variability in slaughter volume across marketing channels. We also confirm the linkage between value‐based production techniques that increase seller information on carcass quality and seller increased usage of grid pricing regardless of actual carcass quality. Empirical evidence is provided in support of the supposition that carcass quality uncertainty plays a role in grid market share variability.  相似文献

Agri‐environmental measures play an important role in Italian rural areas, as shown by the financial commitment to the Rural Development programmes. However, in contrast with other European Union (EU) countries, policy‐makers still have limited experience on how farmers approach environmental incentive schemes. This paper casts new light on this issue from a northern Italian perspective. The rationale of the farmers’ decision‐making process is explored using two multinomial models. The first explains the probability of non‐participation or participation in one of three specific agri‐environmental measures. The model outcomes show that labour‐intensive farming types and high dependency of household income on farming activity constrain farmers’ participation, whereas previous experience, easy‐to‐implement environmentally friendly farm practices and adequate compensation of extra costs encourage participation. The second model explores the effect of farmers’ attitudes and beliefs on their predispositions towards participation in any of the schemes. The results highlight that, besides income factors, the farm's future in the business, and the relationship with neighbouring farmers and their opinions on environmentally friendly practices all have significant effects on adoption of agri‐environmental measures. The paper concludes by suggesting that farmers’ attitudes and beliefs, as well as the local behavioural influences, have to be taken into account when designing and communicating agri‐environmental measures.  相似文献

Sluggish growth in per capita consumption and a downward pressure on beef price at the farm level has required producers to raise cattle that precisely target the meat attributes desired by consumers. Coupled with the consumers' preference for beef with lean tissue and less external fat, the beef packing plants have used the dualistic grading system that emphasizes leanness and palatability; both important to carcass prices. Ultrasound technology can help farmers to produce a carcass with an optimal mix of attributes such as marbling and muscling, and external fat. The results of this study show a high level of accuracy of ultrasound technology in predicting carcass attributes. An estimated hedonic regression model shows that the carcass attributes are reflected on the implicit beef price. Ultrasound technology helps producers to produce carcass with the desired attributes and thus obtain a higher price.  相似文献

Off‐farm labour decisions of a sample of Kansas farmers are evaluated. The central question of our analysis pertains to whether 1996 US farm policy reforms may have altered the decisions to work off the farm. The effects of policy decoupling on off‐farm labour are complex: different aspects of policy changes can have opposing effects on off‐farm work decisions. Essentially, this makes this issue an empirical question. Results show that the introduction of fixed, decoupled payments in 1996 might have reduced the likelihood of off‐farm labour participation. However, the new policy environment may have increased farm households’ revealed aversion to risk, motivating a higher participation in non‐farm labour markets. The effects of 1996 policy reforms on farm income variability could have been attenuated by changes in US crop insurance programmes and by an increase in emergency assistance payments towards the end of the 1990s. The reduction in price supports may have increased the motivation for working off the farm. The net effect of the overall reforms on off‐farm work participation is not likely to have been large.  相似文献

This article assesses the decision to adopt organic farming practices. We use Duration Analysis (DA) to determine why farmers adopt organic farming practices and what influences the timing of adoption. We extend previous studies by including farmers’ objectives, risk preferences, and agricultural policies as covariates in the DA model. The Analytical Hierarchy Process is used as a multicriteria decision‐making methodology to measure farmers’ objectives. The empirical analysis uses farm‐level data from a sample of vineyard farms in the Spanish region of Catalonia. Farmers’ objectives are found to influence the conversion decision. Moreover, farmers who are not risk averse are more likely to adopt organic farming. Results point to the policy changes that have been most relevant in motivating adoption of organic practices.  相似文献

Climate variability with unexpected droughts and floods causes serious production losses and worsens food security, especially in Sub‐Saharan Africa. This study applies stochastic bioeconomic modeling to analyze smallholder adaptation to climate and price variability in Ethiopia. It uses the agent‐based simulation package Mathematical Programming‐based Multi‐Agent Systems (MPMAS) to capture nonseparable production and consumption decisions at household level, considering livestock and eucalyptus sales for consumption smoothing, as well as farmer responses to policy interventions. We find the promotion of new maize and wheat varieties to be an effective adaptation option, on average, especially when accompanied by policy interventions such as credit and fertilizer subsidy. We also find that the effectiveness of available adaptation options is quite different across the heterogeneous smallholder population in Ethiopia. This implies that policy assessments based on average farm households may mislead policy makers to adhere to interventions that are beneficial on average albeit ineffective in addressing the particular needs of poor and food insecure farmers.  相似文献

Lawmakers often subsidize farmers in times of financial distress. This article models this political impulse as a constraint on government farm policy, describing how ex ante government farm insurance can deter ex post "disaster relief" and improve production incentives by countering the moral hazard that otherwise prevails. Absent ex ante government policy, ex post relief takes the form of revenue insurance, which prompts excessive entry into farm production and under-production by operating farmers. Ex ante government policy can raise economic and political welfare by buying out low productivity farmers and offering profitable farmers a combination of revenue insurance, price supports, and a program participation fee.  相似文献

We explore the evolutionary nature of interactions between government policy, farm decision-making and ecosystem services in Shucheng County, Anhui Province, 1950–2015. Analyses of ecological, social and economic trends are complemented by interviews with local farmers. Since the Household Responsibility System started in 1980, there has been a trade-off between rising levels of provisioning services and falling levels of regulating services with evidence that critical thresholds have been passed for water quality. Using a Framework for Ecosystem Service Provision, we argue that farmers have acted only as ecosystem service providers and have not influenced the policies that have brought about the trade-offs. Over the period, ecological degradation is best described as an example of ‘creeping normalcy’ where cumulative conventional actions by individual farmers produce unsustainable losses in regulating services. The Chinese government should act to balance the various ecosystem services through valuation and national policy. In this respect, there is a need for agencies that can provide place-based advice to farmers that will allow them to maintain productivity levels while pursuing restorative actions. Even with new policies, the draw of urban employment, high production costs and an ageing population threaten the viability of farming in these marginal agricultural areas.  相似文献

A foot‐and‐mouth disease outbreak, although having a low probability of occurrence, results in losses of export markets and introduces considerable potential disease management and eradication costs. We develop a dynamic model that integrates beef cattle production, disease dissemination, domestic consumption, and international trade and captures the intertemporal economic welfare impacts of mitigation measures. The model is applied to the case of a hypothetical outbreak in Canada to capture changes in producer profits, consumer price, and government costs due to the outbreak and sums these to measure changes in total economic welfare of the beef industry. Mitigation scenarios are reported for stamping‐out, movement controls, vaccination, and preemptive slaughter.  相似文献

Pakistan is highly vulnerable to extreme climatic events, such as floods and droughts. This study determines the farmers’ risk perception, risk attitude, adaptation measures and various aspects of vulnerability to climate change (e.g. floods, droughts, heavy rainfalls, pests and disease) at farm level in rural Pakistan. The risk perception and attitude of farm households are crucial factors that influence farm productivity, investment and management decisions at this level. A well-designed questionnaire was used to interview 720 farm households from six districts of the Khyber Pakhtunkhwa province. A binary logit model was used to determine the main factors that affect the choice of adaptation strategies of the farm household. The findings revealed that crop diversification, changing crop varieties, altering the crop calendar, varying the fertilizer used, mulching and farm insurance were the main adaptation strategies followed by farm households. The results of the binary logit model revealed that age, education, farm size, household size, credit accessibility, annual income and the perception on the increase in temperature and decrease in rainfall had significant influence on the selection of the adaption strategies. The findings of this study can provide guidance, policy recommendations and reference for future researchers.  相似文献

This paper re-examines the motivation for government intervention in agriculture to support farm prices and incomes. A model is outlined in which the government has a preference for higher farm incomes but fails to provide farmers with the socially optimal level of price support, even when one accepts the government's income redistribution goals as a valid reflection of social preference. It is shown that agricultural policy has an intervention bias: government price supports generally are higher than would be socially optimal. The source of the intervention bias is a time inconsistency in optimal agricultural policy formation, caused by the government's inability to precommit to a rule for setting future price support levels. Simulation results indicate that in some circumstances the intervention bias in agricultural policy can be substantial.  相似文献

Farm succession and inheritance is increasingly considered a complex phenomenon which not only affects core dimensions of farm family life but also the agricultural sector more widely. Intergenerational farm transfer in particular is increasingly viewed as fundamental to the sustainability and development of global agriculture. In the majority of EU countries, the average age of farmers is increasing, while the number of farmers under 40 years of age is decreasing. There is growing concern that this demographic trend may have negative impacts on the agricultural industry because it is younger and not older farmers who are associated with more efficient and effective production practices. The question of what motivates decisions to transfer farms is a complex one, and research to date has not apparently enlightened agricultural policy to the extent that current trends towards an ageing farm population are being managed. This research aims to investigate economic and financial aspects of the policy drivers of farm succession and inheritance in Ireland to understand what it is about the policy environment that is failing to stimulate higher levels of farm transfer. It draws on the Teagasc National Farm Survey data which provides Irish data to the Farm Accountancy Data Network in the European Commission. A hypothetical microsimulation model is used to investigate economic factors of farm transfers, with scenarios created to test these factors and their impacts on the transfer process. The Net Present Value (NPV) of income streams for farmers and their successors are calculated to assess which scenarios have the highest/lowest financial effects. The findings illustrate a range of possible scenarios for farm succession/inheritance, with some results indicating that under current policy retaining a farm until death may be more economically beneficial to a farmer than transferring land before death.  相似文献

Agrobiodiversity can provide natural insurance to risk‐averse farmers by reducing the variance of crop yield, and to society at large by reducing the uncertainty in the provision of public‐good ecosystem services, for example, CO2 storage. We analyze the choice of agrobiodiversity by risk‐averse farmers who have access to financial insurance, and study the implications for agrienvironmental policy design when on‐farm agrobiodiversity generates a positive risk externality. While increasing environmental risk leads private farmers to increase their level of on‐farm agrobiodiversity, the level of agrobiodiversity in the laissez‐faire equilibrium remains inefficiently low. We show how either one of the two agrienvironmental policy instruments can cure this risk‐related market failure: an ex ante Pigouvian subsidy on on‐farm agrobiodiversity and an ex post payment‐by‐result for the actual provision of public environmental benefits. In the absence of regulation, welfare may increase rather than decrease with increasing environmental risk, if the agroecosystem is characterized by a high natural insurance function, low costs, and large external benefits of agrobiodiversity.  相似文献

The farm sector has moved from one that was very homogeneous to one with significant differences in size and/or orientation. The decline in the number of “average‐sized” farm and the growth in the number of large farms are due primarily to technological innovations that push operations producing commodities to grow as a means of capturing economies of size. The increase in the relative number of small farms is also due partially to technical advances that allow for the production of food goods with the desired quality attributes to be delivered to the appropriate market. This market is continually being differentiated due to demographic and income shifts. The growing heterogeneity in farm structure complicates the assessment and design of farm policy. The social policy objective of improving the livelihood of farmers and their families could be achieved through farm support and extension programs when the sector was homogeneous. The policy objective has shifted toward improving the competitiveness of the sector, but for which of its components? The trend toward greater heterogeneity is likely to continue and thus so will the internal and external support for any policies targeted toward the farm sector.  相似文献
