Agricultural Contracting Update, 2005 AgEcon
MacDonald, James M.; Korb, Penelope J..
More than half of all transactions for U.S. agricultural products are still conducted through spot market exchanges, in which commodities are bought and sold in open market transactions for immediate delivery. But a growing share of U.S. farm production is produced and sold under agricultural contracts. Such contracts between farmers and their buyers are reached prior to harvest (or before the completion stage for livestock) and govern the terms under which products are transferred from the farm. The shift of production to contracting coincides with shifts of production to larger farms. Contracts are far more likely to be used on large farms than on small ones. Marketing and production contracts covered 41 percent of the value of U.S. agricultural...

Agricultural Contracting Update: Contracts in 2008 AgEcon
MacDonald, James M.; Korb, Penelope J..
Marketing and production contracts covered 39 percent of the value of U.S. agricultural production in 2008, up from 36 percent in 2001, and a substantial increase over 28 percent in 1991 and 11 percent in 1969. However, aggregate contract use has stabilized in recent years and no longer suggests a strong trend. Contracts between farmers and their buyers are reached prior to harvest (or before the completion stage for livestock)and govern the terms under which products are transferred from the farm. Contracts are far more likely to be used on large farms than on small farms, and they form one element in a package of risk management tools available to farmers. Production contracts are used widely in livestock production, while marketing contracts are...

Agricultural outsourcing: A comparison between the Netherlands and Japan AgEcon
Igata, Masayo; Hendriksen, Astrid; Heijman, Wim J.M..
Outsourcing may well be a tool for increasing the efficiency of Japanese agriculture. However, outsourcing is not frequently used by Japanese farmers in their day-to-day management. This has resulted in a weakly developed market for agricultural contracting services. In order to take a closer look at the reasons for making use of outsourcing, a comparative study was carried out between the agricultural contracting sector in Japan and that in the Netherlands, where agricultural outsourcing is a regular practice. In the Netherlands, especially small, diversified farms that lack sufficient labour tend to outsource agricultural work; in Japan, the situation is far less clear. Cultural factors possibly play an important role.

AGRICULTURAL STRUCTURAL ADJUSTMENT TO GOVERNMENT POLICIES: EMPIRICAL EVIDENCE AgEcon
Ahearn, Mary Clare; Yee, Jet; Korb, Penelope J..
Economic theory alone cannot predict the impacts of government payments on farm structure. We estimate a 5-equation model for the 1978-96 period to measure the impacts using state micro and macro data sets. We found that government payments were positively associated with farm size and farm exits, but negatively associated with the extent of consolidation in farm production and the off-farm work of operators.

Aprecíziós gazdálkodás beruházásainak megtérülése AgEcon
Smuk, Norbert; Milics, Gabor; Salamon, Lajos; Nemenyi, Miklos.
A vizsgálatokból megállapítható, hogy a precíziós gazdálkodás bevezetésére irányuló beruházások megtérülése és az üzemi méretek között szoros az összefüggés. A feltételezett öt- és hatéves megtérülés mellett a hozam- vagy az elvárt kamatszint-változást a nagyobb területű üzemek képesek ellensúlyozni. --Return on investment in projects for implementing precision farming is closely related to farm size. In the event of the envisaged repayment over five or six years, farms with a larger area can balance changes in yield or interest rate.

Challenging Small-scale Farming, A Non-parametric Analysis of the (Inverse) Relationship Between Farm Productivity and Farm Size in Burundi AgEcon
Verschelde, Marijn; D'Haese, Marijke F.C.; Vandamme, Ellen; Rayp, Glenn.
We use a nonparametric estimation of the production function to investigate the relation- ship between farm productivity and farming scale in poor smallholder agricultural systems in the north of Burundi. Burundi is one of the poorest countries in the world, with a predominant small scale subsistence farming sector. A Kernel regression is used on data of mixed cropping systems to study the determinants of production including different factors that have been identified in literature as missing variables in the testing of the inverse relationship such as soil quality, location and household heterogeneity. Household data on farm activities and crop production was gathered among 640 households in 2007 in two Northern provinces of Burundi. Four production...

Changements dans l’allocation des terres, la production et la taille des exploitations dans le secteur des petits exploitants rwandais sur la période 1984/1990 à 2002 AgEcon
Mpyisi, Edson; Weber, Michael T.; Shingiro, Emmanuel; Loveridge, Scott.
There have been major shifts/changes in land use patterns in Rwanda over the past twelve years. A few striking observations include: As a percentage of total farmland, cultivated land increased. The increase in cultivated land occurred at the expense of pasture and fallow and woodlot. The share of pasture and fallow decreased from 22% in 1990 to 14% in 2002 and woodlot decreased from 11% in 1990 to 7% in 2002. This trend of increasing cultivated land is apparent from the mid-eighties to today. These observations imply that land is being farmed much more intensively without much time to fallow and allow the soil to rejuvenate. Pasture and woodlot are also being cut down at the expense of cultivation. This has important potential implications for...

CHANGES IN LAND UTILIZATION IN HUNGARY SINCE THE TRANSITION AgEcon
Magda, Robert.
The paper discusses the fluctuation of the proportion of cultivation, the development of agrarian operating and organizational structure, the separation of estate tenancy and land use, along with the change of law. In the backward areas and territories with adverse endowment, further questions remain open during the temporal changes of land use. My study is not only limited to the description of changes, but also aims to illustrate general conclusions relating to the preferred structure and proportion of land use in Hungary.

Commodity Payments, Farm Business Survival, and Farm Size Growth AgEcon
Key, Nigel D.; Roberts, Michael J..
In the last 25 years, U.S. crop farms have steadily declined in number and grown in average size, as production has shifted to larger operations. Larger farms tend to receive more commodity program payments because most payments are tied to a farm’s current or historical production, but whether payments have contributed to farm growth is uncertain. This study uses farm-level data from the census of agriculture to determine whether there is a statistical relationship between farm commodity program payments and greater concentration in production. The analysis indicates that, at the regional level, higher commodity program payments per acre are associated with subsequent farm growth. Also, higher payments per acre are associated with higher rates of farm...

Conventional Tillage versus No-till: Characteristics of Producers and Farms AgEcon
Djido, Abdoulaye Ibrahim; Vitale, Jeffrey D.; Epplin, Francis M..
A survey of Oklahoma farmers was conducted to determine characteristics of farms across three tillage categories: conventional tillage exclusively; no-till exclusively; other (combination of systems). The seven percent that use no-till exclusively crop more acres, rent more acres, and use more crop rotations than farms that use conventional tillage exclusively.

Corporate farm size determinants in transitional economy: the case of the Moscow region AgEcon
Svetlov, Nikolai M..
A set of dynamic DEA models is applied to investigate size determinants on the Moscow region corporate farms during 1996-2004. The institutional theoretical framework is found to be relevant to explaining corporate farm sizes and their changes in the Moscow region, unlike the neo-classical framework. Farms' opportunities to utilize returns to scale for improving performance are minor. Rank correlation between performance and size indicators is positive. This cannot be comprehensively explained by wider opportunities to grow that are available to best-practice farms. The theoretical expectation of pursuing lower transaction costs as a motivation for a large-scale farm business complies with the estimations.

Dairy Quota and Farm Structural Change: A Case Study on the Netherlands AgEcon
Jongeneel, Roelof A.; Tonini, Axel.
This paper sets out to analyse the impact of milk quotas had on the dairy farm structure of the Netherlands. In addition projections on the likely farm structure under different milk quota scenarios are explored. Moreover mobility indicators characterizing structural change are developed and calculated. A Markov probability model is estimated relying on a generalized cross entropy approach. The introduction of milk quotas as of April 1, 1984 froze the dairy farm structural adjustment, at least initially. However, later on mobility started to increase, which is likely to reflect the quota tradability and lease possibilities. Moreover there is evidence that the milk quota regime has increased concentration of dairy production among farms with 50-69 cows. If...

Determination of relationship between wheat farm size and energy indexes in west Azerbaijan province, Iran CIGR Journal
Sedaghat Hosseini, Morteza; Mohammadi, Ahmad; Arezou, Mohsen; Koorang Beheshti, Amir Masoud.
The objective of this study was to determine the relationship between farm size and energy productivity of wheat production in west Azerbaijan province, Iran.  Farmers with different farm sizes (less than two hectares, between two and five hectares and more than five hectares) were randomly selected.  Questionnaires were filled by 61 farmers.  Then total used energy, produced energy, energy productivity and energy ratio were calculated for each farm.  Also the relationship between energy indexes and three methods of tillage and planting (combination machine, seed drill and seed spreader) and three harvesting methods (combine harvester, mower and hand tools) were calculated.  The data were analyzed by SPSS software.  The results showed that fertilizers...

Diversifikation und Wachstum landwirtschaftlicher Unternehmen AgEcon
Weiss, Christoph R.; Thiele, Holger D..
The liberalization of agricultural markets has increased the interest of farmers (as well as those working on policies concerned with their welfare) in agricultural diversification strategies. However, empirical research on diversification in European agricultural markets is very limited. This paper follows OUSTAPASSIDIS (1992) and investigates the relationship between different diversification strategies and farm performance (farm growth rates). The results of fixed– and random-effect models for approx. 3900 farms in Schleswig-Holstein for the period 1988/89–1997/98 show that diversification into related products increases growth rates whereas the opposite applies for diversification into unrelated products. Initial farm size has a significant and...

Do Government Payments Influence Farm Size and Survival? AgEcon
Key, Nigel D.; Roberts, Michael J..
Using farm-level data from the 1987, 1992, and 1997 Census of Agriculture, this study estimates what effect agricultural payments have had on the likelihood of farm business survival and on farm size. The unique panel data set permits conditioning current farm size on past farm size, which removes much of the individual heterogeneity of farms that could be spuriously correlated with payment levels. Results indicate that between consecutive censuses, past per acre payments have a significant positive effect on farm business survival and a small yet significant influence on the size of continuing farms.
