Organic or conventional? Optimal dairy farming technology under the EU milk quota system and organic subsidies

This paper assesses the competitiveness of organic and conventional dairy farms under different milk market and organic farming policy scenarios. We use a DEA-based model to estimate for each policy scenario the sample farms’ profit potential in both technologies. The model enables identification of a farm’s optimal technology based on its input–output observations. The empirical analysis is based on the annual accounts of 1300 Bavarian dairy farms. Results indicate that approximately 69% (78%) of the organic (conventional) farms have chosen their optimal farming system. The remaining organic (conventional) farmers could increase their profit on average by roughly 6% (10%) by switching to the other technology. Abolishment of the EU milk quota results in a considerable decline in the number of sample farms for which organic farming is the optimal technology, suggesting that, ceteris paribus, organic dairy farms may lose competitive advantage with the deregulation of the EU’s milk market regime in 2015. Organic maintenance payments more than double the number of farms with a higher earning potential in organic farming, but their effectiveness could decline when the milk quota is abolished.     

Farm locations and dwelling clusters: Do they make production and technical efficiency spatially contagious?

In the last decades, local rice supplies in the Philippines have fallen short of local demand. As a result, the Philippines has become a net importer of rice. Reacting to this situation, the Philippine government introduced the Food Staples Sufficiency Program (FSSP) in 2012 with the belief that the Philippines can attain rice self-sufficiency. As physical farm expansion yields only 20% of the necessary increase in production, the remaining 80% must come from increased productivity. This study uses a sample of rice production areas in Central Luzon as representative of rice production in the Philippines. Stochastic production frontier analysis revealed that the average technical efficiency of farms in Central Luzon ranges between 0.76 and 0.92 in the wet and dry seasons. Increasing farm productivity can help attain the FSSP production target by potentially increasing yield per hectare. A combination of spatial econometrics with geostatistical tools demonstrated the presence of spatial dependence in yield and farm performance. Results show significant clustering of best and worst performing farms, specifically in Tarlac City. To increase farm technical efficiency and help attain food production targets at national and even global levels, policy interventions should consider focusing on geographically prioritized areas for technical efficiency improvement.     

Can the small dairy farm remain competitive in US agriculture?

Smaller dairy farms in the US are observed to have higher costs than larger farms, and whether those higher costs are due to technology or inefficiency has implications for policy to address the small farm. If high cost of production on smaller farms is due to a higher cost frontier, then to make small farms competitive would require research to devise and design technology that is suitable for small farms. If instead high cost is due to inefficiency, then educational approaches are needed to ensure small dairy farms use technology efficiently. To determine the cause of higher costs on small farms, the cost of milk production by farm size was decomposed into frontier and efficiency components with a stochastic cost curve using data on USA dairy farms. Although the frontier cost of production decreases with farm size, that cost reduction is not as pronounced as a cost curve that includes inefficiency. The higher cost of production on many smaller farms is caused by inefficiency rather than technology.     

Dependency of organic farms on direct payments in selected EU member states: Today and tomorrow

This paper examines the development of the role of government support in the financial situation of organic farms in selected Western and Eastern European countries, contrasting dependency on direct payments with that of conventional farms and assessing the impact of foreseeable changes in the political and economic environment. The results show that direct payments play an important role in the financial viability of organic farms in both Western and Eastern European countries. The level of specific support for organic farming is put into perspective, as other support payments and market returns contribute larger shares to total farm revenue in all the countries analysed. Modelling analyses show that support payments will continue to play an important role in the profitability of organic farms in Western Europe after implementation of the 2003 reform of Common Agricultural Policy in the EU. For organic farmers in Eastern European countries, the importance of support payments increases strongly with EU accession, as first pillar payments are introduced and environmental payments are expanded significantly.     

Profit efficiency among Bangladeshi rice farmers

Production inefficiency is usually analyzed by its three components—technical, allocative, and scale efficiency. In this study, we provide a direct measure of production efficiency of the Bangladeshi rice farmers using a stochastic profit frontier and inefficiency effects model. The data, which are for 1996, include seven conventional inputs and several other background factors affecting production of modern or high yielding varieties (HYVs) of rice spread across 21 villages in three agro-ecological regions of Bangladesh. The results show that there are high levels of inefficiency in modern rice cultivation. The mean level of profit efficiency is 77% suggesting that an estimated 23% of the profit is lost due to a combination of technical, allocative and scale inefficiency in modern rice production. The efficiency differences are explained largely by infrastructure, soil fertility, experience, extension services, tenancy and share of non-agricultural income.     

Privatization of agricultural extension services in the EU: Towards a lack of adequate knowledge for small-scale farms?

Small-scale farming involves millions of households in the EU and plays an important role in the rural economy. A significant percentage of these farms produce commodities for the market. This productive dimension is often overlooked, however, as is the technical support needed by these farms. The privatization of national farm advisory systems (NFAS) has an impact on small-scale farming that should be better assessed. This paper, which looks at the characteristics of intangible services, helps demonstrate how the privatization of advisory services may have unexpected adverse effects on small farms. The dismantling of coordinating authorities has made these farms less visible as a target client. Less direct interaction with advisors makes it more difficult to co-produce knowledge that is relevant to their needs. In addition, back office activities such as scientific monitoring, building and updating databases and scientific experiments have been restructured in a way which does not support their interests.     

Flawed Competition Policies: Designing ‘Markets’ with Biased Costs and Efficiency Benchmarks

Rather than the endogenous, tournament-type regulation based on mean costs proposed by Shleifer almost twenty years ago, regulators have opted for market designs based on exogenously determined efficiency comparisons reflected in fixed productivity adjustments. These productivity assessments are based only on estimates of technical efficiency improvements derived from estimated production frontiers. Utilities’ prices and potential profits are driven by this externally determined market. This paper examines the impacts on utility efficiency rankings from variations in peer group frontier regulation in Europe and Australia as well as in its use in the U.S. Despite the potential for distortions caused by long periods with non-market prices, these regulatory applications measure only technical efficiency, leaving moot the assessment of optimal input selection. We examine both technical and allocative efficiency variations among firms from the different cost specifications employed by regulators involving output, factor inputs, and costs. How are rankings impacted when only subsets of total costs (e.g., O&;M, not capital or system losses) are used to gauge efficiency? Does the use of partial measures of capital relying on physical specifications impact efficiency rankings? Are rankings affected when comparisons are made independently one input at a time? Is the efficiency frontier stable? Finally, we compare alternative yardstick measures to a simple ranking on relative (total) cost per unit.

Disparity in Production Efficiency of China's TVEs Across Regions: A Stochastic Frontier Production Function Approach

This study aims to empirically examine the changes in production efficiencies of China's township and village enterprises (TVEs) between 1988 and 1993 with particular reference to the spatial disparity of these changes. The stochastic frontier production model, which incorporates inefficiency effects, is adopted in the study. Findings of this study indicate that the technical production efficiency of China's TVEs had, on average, declined between the six years under study. Furthermore, the findings also suggest that the industrial performance of China's TVEs (in terms of production efficiency), like the development.     

Impact of contracts in high yielding varieties seed production on profits and yield: The case of Nepal

Nepal’s population continues to grow, but the agricultural sector’s performance remains almost stagnant. This has led to a decline in the per capita availability of food. Increasing agricultural productivity is the key to agricultural growth, and one strategy for increasing agricultural productivity is to use improved seeds. This study investigates the impact of contract farming (CF) in high yielding varieties (HYV) of paddy seed production on costs, yield, and profits of smallholder farms in Nepal. Using farm-level data and a non-parametric propensity score matching estimator, the study finds a significant positive impact of contract HYV seed farming on revenues, profits, and yield, and a significant negative impact on total costs of production. Additionally, very small farms (⩽0.43 ha) with CF in HYV paddy seeds tend to gain the most when it comes to yield per hectare. Our estimates reveal that the average smallholder household in Nepal engaged in CF with input conditions receives higher profits. However, farmers engaged in CF with output conditions tend to have higher yields but smaller profits. Finally, farmers engaged in CF in HYV paddy seeds with both input and output conditions have the highest yield gains and significantly higher profits.

The evolution of hog production and potential sources for future growth in China

Following reforms to the market, China’s hog industry has developed rapidly, however, with social and economic transitions, China’s hog industry is facing challenges which might restrict long-term growth in production. This paper analyzes the changes in regional scale, organization, input factors, and technological progress for China’s hog production over the last few decades. The paper seeks to reveal the sources of hog production growth and provide some suggestions for future development of the hog industry. To achieve these aims, the paper uses stochastic frontier production functions and the Malmquist index to measure total factor productivity (TFP) in the hog industry and decompose TFP into technical efficiency; technological progress; scale efficiency; and allocative efficiency using data for 25 provinces from 1980 to 2008. The results show firstly that; the TFP of hog production increased by 64.3% from 1980 to 2008, and allocative efficiency and scale efficiency improvements played a key role in this TFP growth. In contrast, technical efficiency and technical progress have changed little over this period. Secondly, TFP’s contribution to output was 39.7%, it being less than that of factor inputs to output. Thirdly, the results suggest that the growth of China’s pork production depends mostly on the increase in the quantity of factor inputs, especially feed. As a consequence, the key to ensuring long-term and stable development of China’s hog production would seem to involve focusing on enhancing total factor productivity and changing the pattern of production growth.     

Produce growers’ cost of complying with the Food Safety Modernization Act

Small and medium size growers using both conventional and sustainable farming practices have expressed concern that compliance with the Produce Rule implementing the Food Safety Modernization Act will be prohibitively costly. We use data from an original national survey of fruit and vegetable growers to examine that contention. In particular, we analyze how expenditures on food safety practices required by the Produce Rule vary with farm size using a double hurdle model to control for selectivity in both using food safety practices and reporting expenditures. We find that expenditures per acre decrease with farm size. We also find some evidence that growers using sustainable farming practices spend more than conventional growers on many food safety practices. We use our estimates to quantify how the cost burden of compliance varies with farm size. We then explore the policy implications of exemptions to the Rule by simulating how more stringent exemption thresholds for farm revenue and share of direct sales might affect the cost burden of each food safety practice on farms at the threshold.     

The Effect of Management Buyouts on Firm–level Technical Inefficiency: Evidence from a Panel of UK Machinery and Equipment Manufacturers

The longer–term technical efficiency effects of management buyouts (MBOs) are evaluated using a stochastic production frontier approach on a panel of UK manufacturing firms. The results, based on the period 1986–1997, indicate that firms with the MBO governance structure: (1) have higher efficiency in the two years before the transaction but not prior to that; (2) have efficiency 7%, 7.5%, 4%, and 7% higher in each of the first four years post–buyout; (3) do not have superior efficiency beyond the fifth year post–buyout. This is consistent with MBOs creating managerial incentives that improve firm–level performance.     

Measurement of competitiveness in smallholder livestock systems and emerging policy advocacy: An application to Botswana

Farm level cross sectional data of 556 randomly selected livestock producers were used to investigate the competitiveness of smallholder beef farmers in Botswana. The results show the presence of inefficiency, with about 74% of the variation in actual profit from maximum profit (profit frontier) between farms mainly arising from differences in farmers’ practices rather than random variability. Further the mean profit efficiency level of 0.58 suggests that there is a substantial scope to improve beef profitability in Botswana. Significant profit efficiency drivers include, among others, education, distance to market, herd size, access to information and access to income from crop production. Considering the importance of livestock sector for wealth creation and poverty eradication in the rural areas where poverty is more pronounced, there is a need for appropriate development strategies and policies directed towards addressing these factors. In particular there is need to invest in market infrastructure in order to improve market access, hence profit efficiency of smallholder livestock farmers.     

Market Structure and Hospital Efficiency: Evaluating Potential Effects of Deregulation in a National Health Service

In this article we examine the potential effect of market structure on hospital technical efficiency as a measure of performance controlled by ownership and regulation. This study is relevant to provide an evaluation of the potential effects of recommended and initiated deregulation policies in order to promote market reforms in the context of a European National Health Service. Our goal was reached through three main empirical stages. Firstly, using patient origin data from hospitals in the region of Catalonia in 1990, we estimated geographic hospital markets through the Elzinga–Hogarty approach, based on patient flows. Then we measured the market level of concentration using the Herfindahl–Hirschman index. Secondly, technical and scale efficiency scores for each hospital was obtained specifying a Data Envelopment Analysis. According to the data nearly two-thirds of the hospitals operate under the production frontier with an average efficiency score of 0.841. Finally, the determinants of the efficiency scores were investigated using a censored regression model. Special attention was paid to test the hypothesis that there is an efficiency improvement in more competitive markets. The results suggest that the number of competitors in the market contributes positively to technical efficiency and there is some evidence that the differences in efficiency scores are attributed to several environmental factors such as ownership, market structure and regulation effects.     

Rice farming in Nigeria : in praise of the smallholder

Food production policy in Nigeria is now oriented towards large scale commercial production. The Federal Government proposes 20000 hectares of public cassava farming in all 19 states and in the Abuja capital territory. The National Grains Board and the National Root Crops Production Company are establishing large farms in their operational zones. The Nigerian Agricultural and Cooperative Bank is loaning millions of naira to individual private farmers to encourage them to establish large farms. Virtually every state government has its Agricultural Development Corporation directly involved in agricultural production on a large scale. It is presumed that the smallholder system on which Nigeria currently depends is inefficient and could not be relied upon to achieve the necessary increases in production.     

Potential for recoupling production and consumption in peri-urban territories: The case-study of the Saclay plateau near Paris,France

With growing urbanization worldwide, urban sprawl is leading to the extension of peri-urban areas in most countries. These dynamic areas, subjected to pressure from urban planning, are contributing to the uncoupling of consumption and local agriculture. In this article we study the feasibility of recoupling production and consumption within the agri-food system of the peri-urban area of the Saclay plateau near Paris.By using a nitrogen flow analysis based on the concept of territorial ecology, we analysed quantitative and qualitative data providing information in terms of system performances. By calculating two local efficiency indicators (one production-based indicator and one consumption-based) and a self-sufficiency capacity indicator, we assess the current and potential coupling between production and consumtion. A typology of farming systems was constructed to assess the more efficient type of farms in terms of “localisation within the agri-food system.The Saclay plateau has many assets to increase local agri-food system efficiency and to work towards “agricultural symbiosis”. However, a number of obstacles remain on both the production and the demand sides. Our study illustrates the lack of consideration of the productive function of urban and peri-urban agriculture in urban planning projects. The methods developed and the results achieved are a step towards a better integration of food issues in land planning.     

Targeting agricultural research and extension for food security and poverty alleviation: A case study of fish farming in Central Cameroon

Over 5 years of participatory on-farm research, market access, profitability, farming systems productivity and economic sustainability were compared on 100 small-scale farms in Central Cameroon. Integration technology based on the use of agricultural by-products as fishpond inputs was the driver for intensification. Over all farms, fishpond productivity increased from 498 kg to 1609 kg fish/ha (2145 kg/ha/yr). During the project period, the number of active fish farmers increased from 15 to 192 (including 55 farms which participated only through information exchange). Over all farms, net returns from aquaculture increased by 5 times over pre-project levels. Productivity, intensity and profitability increased more significantly in periurban areas with good market access, compared to rural areas. Among farmers with good market access, average net income from the aquaculture enterprise rose from $118 up to $1485. Research-Extension Team (RET) support cost an average of $61,300 per year. Over 5 years, rural farmers recaptured 23% of the relevant RET investment compared to 442% by periurban farmers. Likewise, increase in production attributable to RET intervention was higher for periurban (253%) compared to rural (11.3%) fish farmers. Within 3 years of the end of extension support, rural farmers had returned to pre-project production levels, whereas periurban farms had better maintained their productivity and profitability. Findings indicate that, in areas with little or no access to markets, the number of fishponds and fish farmers can be increased and yields improved, increasing local food supplies, but sustainability in the absence of extension subsidies is questionable. To achieve either of the two principal goals for the sector, food security and/or poverty alleviation, investments need to be made in improving the availability of quality technical assistance to targeted farmers and finding means of reducing social conflict arising from perceived inequalities in the accrual of the benefits of development.     

Technical,quality and environmental efficiency of the olive oil industry

This paper studies the level of technical efficiency in the olive oil industry from a multi-output perspective, and examines olive oil production in quantitative and qualitative terms. The study also covers the environmental impact of the production process. These are key issues due to the current environmental, organoleptic and food traceability requirements of the EU Common Agricultural Policy (CAP). Furthermore, product differentiation is sought after in today’s ever more demanding markets. The production of olive oil in Andalusia (Spain) is the most important agricultural food industry in the whole region and it represents 30% of world olive oil production. Three data sources have been used: a comprehensive survey to a sample of olive oil producers, their financial reports, and the opinion of a group of experts in olive oil production techniques interviewed by means of the Delphi survey. With this data and after the construction of indicators, a production frontier is elaborated by applying an extension of the Data Envelopment Analysis (DEA) technique. This will allow for the measuring of the relative technical efficiency indices and set specific efficiency indices for both the quality of the oil produced and the environmental impact of the production process. Those factors impacting on efficiency are determined by a truncated regression model with bootstrap. The results show a medium–high level of relative technical efficiency and highlight the importance of efficiency factors involving production and marketing associations.
