Algumas causas da nao adocao das tecnologias de convivencia com a seca pelos pequenos produtores rurais da regiao semi-arida do Nordeste brasileiro: um estudo de caso. Repositório Alice
CAVALCANTI, N. de B.; OLIVEIRA, C. A. V.; BRITO, L. T. de L.; REIS, E. M..
A melhoria das condicoes de vida dos pequenos produtores rurais da regiao semi-arida do Nordeste brasileiro, depende dos fatores socioeconomicos, geoambientais e do suporte tecnologico a disposicao desses agricultores. Alguns trabalhos mostram que a melhoria das condicoes de renda e, consequentemente das condicoes de vida dos pequenos agricultores, depende de um aumento da produtividade dos fatores de producao escassos. Esta transformacao realiza-se, em grande parte, pelo progresso tecnologico. A adocao de tecnologias de producao mais eficientes aumenta a rentabilidade de empresa agricola, que pelo aumento da produtividade fisica das culturas ou criacoes existentes ou a serem produzidas, quer pela reducao dos custos de producao, tecnicas de conservacao de...

An Ex Post Evaluation of the Conservation Reserve, Federal Crop Insurance, and Other Government Programs: Program Participation and Soil Erosion AgEcon
Smith, Vincent H.; Goodwin, Barry K..
Recent research has questioned the extent to which government policies, including conservation and risk management programs, have influenced environmental indicators. The impacts of income-supporting and risk management programs on soil erosion are considered. An econometric model of the determinants of soil erosion, program participation, conservation effort, and input usage is estimated. While the Conservation Reserve Program has reduced erosion an average of 1.02 tons per acre from 1982 to 1992, approximately half of this reduction has been offset by increased erosion resulting from government programs other than federally subsidized crop insurance.

Average Crop Revenue Election, Crop Insurance, and Supplemental Revenue Assistance: Interactions and Overlap for Illinois and Kansas Farm Program Crops AgEcon
Zulauf, Carl R.; Schnitkey, Gary D.; Langemeier, Michael R..
Farm-level data from Illinois and Kansas for the 1991–2007 crops are used to examine the interaction and overlap among crop revenue insurance, Supplemental Revenue Assistance (SURE), and Average Crop Revenue Election (ACRE). Compared with 75% Crop Revenue Coverage Insurance (75% CRCP), ACRE provides more payments and has a greater impact on minimum farm revenue for the Illinois farms. In contrast, for the Kansas farms, 75% CRCP has the greater impact. SURE’s relative impact on the Illinois and Kansas farms depends on the metric. The overlap in payments from ACRE and 75% CRCP resulting from covering the same part of the revenue risk distribution is estimated to be less than 5% of ACRE payments. Several proposals for improving the farm safety net are...

Competing Visions of U.S. Agriculture: Can We Have Our Cake and Eat It Too in Reforming Federal Farm Policy AgEcon
Dobbs, Thomas L..
Two alternative visions for U.S. agriculture are described—“the global competitiveness vision” and the “sustainable agriculture vision”—together with farm policy reform proposals associated with each vision. The USDA’s proposed policy reforms (released in January 2007) also are briefly explained and compared to those of groups associated with the global competitiveness and sustainable agriculture visions. The author closes the article with a discussion of the compatibility of different reform proposals and the challenges of passing legislation containing major policy reform.

Complexity and Obsolete Data Concepts: Canadian Farm Policy, and the Changing Structure of Agriculture AgEcon
Freshwater, David.
Agricultural data systems remain based upon now obsolete concepts. In particular, the "full-time, family farm" is still organizing concepts for much of the farm data system, and for agricultural policies. Yet farming has clearly bifurcated into: a relatively small number of large farms that produce the majority of the food and fiber; and a large number of small part-time farms that depend mainly on off-farm income for household well-being. Both types are family farms, but they are not the family farms of the past. It is broadly recognized that large farms pose complex challenges for data collection and policy. But small farms are also complex. While small farms may not account for much production they are important for land use issues and for maintaining...

ENVIRONMENTAL EFFECTS OF AGRICULTURAL LAND-USE CHANGE: THE ROLE OF ECONOMICS AND POLICY AgEcon
Lubowski, Ruben N.; Bucholtz, Shawn; Claassen, Roger; Roberts, Michael J.; Cooper, Joseph C.; Gueorguieva, Anna; Johansson, Robert C..
This report examines evidence on the relationship between agricultural land-use changes, soil productivity, and indicators of environmental sensitivity. If cropland that shifts in and out of production is less productive and more environmentally sensitive than other cropland, policy-induced changes in land use could have production effects that are smaller-and environmental impacts that are greater-than anticipated. To illustrate this possibility, this report examines environmental outcomes stemming from landuse conversion caused by two agricultural programs that others have identified as potentially having important influences on land use and environmental quality: Federal crop insurance subsidies and the Conservation Reserve Program (CRP), the Nation's...

Evaluating the Dynamic Nature of Market Risk AgEcon
Hubbs, Todd; Kuethe, Todd H.; Baker, Timothy G..
This study examines the systematic risk present in major crops for the United States and three corn-belt states. An index of commodities is used in conjunction with cash receipts to generate dynamic estimates of the systematic risk for each crop and state. In our study, we find that beta estimates from a time varying parameter model (FLS) and OLS formulation are substantially different. From our graphs of betas over time, one gains insight into the changing nature of risk and the impact of institutional and macroeconomic events. Systematic risk is shown to increase for most crops over the analyzed period with significant changes in volatility after the collapse of the Bretton Woods Accord.

FINANCIAL IMPLICATIONS OF A NEW FARM POLICY ENVIRONMENT AgEcon
Vandeveer, Lonnie R.; Henning, Steven A.; Kennedy, Gary A.; Li, Chunxiao.
The 1996 Federal Agriculture Improvement and Reform (FAIR) Act dramatically affects the decision-making environment of farms by introducing provisions for reducing farm income support payments. These program changes are likely to affect not only farm incomes, but also farm capital asset markets. The combined effect of these two financial variables is expected to alter the risk position and the debt repayment capacity on farms. Empirical results of this analysis indicate that the absence of farm income support payments reduces debt repayment capacity and increases the risk position on a representative Louisiana cotton-soybean farm.

GLOBAL AGRICULTURAL LIBERALIZATION: AN IN-DEPTH ASSESSMENT OF WHAT IS AT STAKE AgEcon
van der Mensbrugghe, Dominique; Beghin, John C..
We use the global Linkage model to assess the impact of trade and support policies in agriculture on income, trade, and output patterns. We provide order-of-magnitude estimates of the impacts of policy changes rather than point estimates. Two sets of simulations are used to identify key drivers in the results. One set decomposes the aggregate results by looking at the impacts of partial reforms, regionally and across instruments, to identify the relative contribution to global gains of reforms in industrialized and developing countries and of border protection versus domestic support. The second set responds to critics of trade reform (inflated gains for developing countries, no transition costs for industrial country farmers, uncertain supply response in...

How Coupled are Decoupled Farm Payments? A Review of Coupling Mechanisms and the Evidence AgEcon
Bhaskar, Arathi; Beghin, John C..
This survey paper explores the literature on decoupling of farm programs that has emerged in the last 10 years. The paper identifies and assesses the various channels of potential coupling of decoupled farm payments and provides taxonomy of coupling mechanisms found in theoretical and empirical papers. Coupling of decoupled payments is pervasive but effects when measurable are small, with the exception of the impact on land values. The paper points to unresolved issues on potential coupling mechanisms for further research.

Influence of Political Campaign Contributions by American Agribusiness Firms on U.S. Farm Policy AgEcon
Serrao, Amilcar.
This study adapts Ndayisenga and Kinsey's econometric model of the allocation of political campaign contributions by agribusiness firms. This model combines information on campaign contributions for political influence with the behavior assumption of profit maximization to test the hypotheses that agribusiness firms do not lobby against farm policies. Model results support the hypotheses and show that lobbying expenditure in output markets is statistically significant, and that political campaign contributions to the Democratic Party significantly correlate with agribusiness firms' profits. The conclusions of this study provide useful information about the intentions of agribusiness firms that participate in the political market, but the results should be...

Lessons Learned in the Southern Region after the First Year of Implementation of the New Commodity Programs AgEcon
Campiche, Jody L.; Harris, Wesley L..
The development of the commodity programs in the 2008 Farm Bill involved the origination of two complex revenue support initiatives. The two new programs, Average Crop Revenue Election (ACRE) and Supplemental Revenue Assurance (SURE), expanded the risk management tool kit of agricultural producers. The SURE program is a permanent disaster assistance program, whereas the ACRE program is a revenue-based commodity program offered as an alternative to the price-based Direct and Counter-Cyclical Program (DCP) created in the 2002 Farm Bill. For the 2009 signup, only 7.7% of eligible U.S. farms enrolled in the ACRE program. In the southern region, three states had no farms electing ACRE and four others had less than 50. Excluding Oklahoma, less than 1% of all...

Major Forces and Factors Shaping Global Markets: The Emerging Agricultural World AgEcon
Brookins, Carole L..
The world is producing greater opportunity for more people than ever before in the history of mankind. The global agri-food system is dynamic, not static. In order to understand the future trends and potentials for utilizing and improving our agri-food system, it is critical to focus on forces that will improve both productivity and policy to meet the demands of the ever-changing global market. This paper identifies five major trends that will impact the global economy and create structural change in commodity markets.

Measuring Farm Net Income To Better Achieve Policy Objectives AgEcon
Freshwater, David.
The farm problem is a longstanding topic in agricultural economics, and farm organizations continue to press claims that they are disadvantaged and deserve public support. While society may choose to support farmers it is clear that existing farm programs to not do an effective job of providing support. Farm income and farm subsidies are highly concentrated and the lowest income farmers receive little support. Moreover most households with low farm income typically manage their farm to achieve this goal. Politically, commercial farms require that hobby farms continue to be recorded as actual farms in order to mask the small number of enterprises that actually benefit from farm programs. Whether this lead to good public policy is another matter.

Taxpayer Preferences for Farm Policy and USDA Budget Expenditures AgEcon
Ellison, Brenna D.; Lusk, Jayson L.; Briggeman, Brian C..
Current debates on food and farm policy would benefit from an improved understanding of the public’s demand for the services provided by the USDA. We determine taxpayer’s preferences for six categories of USDA expenditures using data from a nationwide survey of almost 1,200 taxpayers. We find that taxpayers believe food safety and inspection is the most important service provided by the USDA. Although there is significant heterogeneity in people’s preferences, our results reveal that at current expenditure levels, most consumers are willing to give up some of the outcomes and benefits provided by expenditures on farm support programs to obtain more of the benefits and services provided by expenditures on food safety and inspection, natural resources and...

The 20th Century Transformation of U.S. Agriculture and Farm Policy AgEcon
Dimitri, Carolyn; Effland, Anne; Conklin, Neilson C..
The structure of farms, farm households, and the rural communities in which they exist has evolved markedly over the last century. Historical data on a range of farm structure variables—including the value of agricultural production, commodity specialization, farming-dependent counties, and off-farm work—offer a perspective on the long-term forces that have helped shape the structure of agriculture and rural life over the past century. These forces include productivity growth, the increasing importance of national and global markets, and the rising influence of consumers on agricultural production. Within this long-term context of structural change, a review of some key developments in farm policy considers the extent to which farm policy design has or has...

The Devil's in the Details: Why a Revenue-based Farm Program is No Panacea AgEcon
Coble, Keith H..
Producer and other interest groups are beginning to consider farm policy positions in anticipation of hearings and possible serious farm bill debates during late 2006 and 2007. An idea gaining attention and support among some groups is deemphasizing or eliminating the current commodity "price" programs (loan deficiency payments and counter-cyclical payments) and replacing them with programs based on "revenue insurance" designs. Suggested designs include a multi-tiered farm payment program based on individual revenue guarantees and shortfalls in county revenue. Another example of such an alternative design is a whole-farm revenue design that issues program payments when adjusted gross farm revenue falls below a historical five-year baseline. Interestingly,...

THE IMPACT OF POLITICAL CONTRIBUTIONS BY FOOD MANUFACTURING FIRMS ON U.S. FARM POLICY AgEcon
Kinsey, Jean D.; Ndayisenga, Fidele.
This study generates an econometric model of the allocation of political contributions by food firms. It combines information about food firms' total expenditures for political influence with the behavioral assumption of profit maximization to test the hypothesis that food manufacturing firms do not lobby against farm policies. The results support the hypothesis. The inferences are conditional on the effects observed in the sample. The conclusions from this analysis may not be widely generalizable, but they do inform hypotheses about the intentions of food firms that participate in the political market.

THE INDUSTRIALIZATION OF AGRICULTURE: IMPLICATIONS FOR FUTURE POLICY AgEcon
Gray, Allan W.; Boehlje, Michael.
Farming is in the midst of a major transformation-not only in technology and production practices, but also in size of business, resource (land) control and operation, business model and linkages with buyers and suppliers. This paper describes the fundamental drivers of today's structural change in U.S. agriculture. The impact of the drivers are illustrated by describing some illustrations of the kinds of innovative farming operations that are developing in agriculture, not the typical farms but those who appear to be leading and shaping the new agriculture. Finally, farm policy implications of the transformation of farming to an industrial manufacturing model are discussed.

The Post-Buyout Experience: Peanut and Tobacco Sectors Adapt to Policy Reform AgEcon
Dohlman, Erik; Foreman, Linda F.; Da Pra, Michelle.
Marketing quota and price support programs for peanuts and tobacco were a longstanding feature of U.S. farm policy, from the 1930s until the Government enacted quota buyouts, in 2002 for peanuts and 2004 for tobacco. Quota owners were compensated with temporary payments, but elimination of the quota programs exposed producers more to market risks and brought about structural changes at farm, regional, and marketwide levels. Since the buyouts, many peanut and tobacco farms have exited production. The farms that remain are mostly larger and have adopted new risk management strategies, such as contracting. Freed of the planting restrictions in the quota programs, production of peanuts, and to a lesser extent of tobacco, has been relocated to regions better...
