SABIIA - Sistema Aberto e Integrado de Informação em Agricultura (Sabiia)

This research work uses stochastic frontier analysis (SFA) and data envelopment analysis (DEA) to examine the sources of agricultural productivity growth over time and of productivity differences among countries and regions in European Union over the period 1980-1998. A comparison of the mean productivity scores obtained by the two approaches show that DEA results are higher than in SFA results, because DEA fits a tighter (more flexible) frontier than the translog frontier. This study is a valuable warning for people to be carefully about the effects of the methodology choice upon their results and to use more than one approach if they suspect that it may have some influence.

AGRICULTURAL PRODUCTIVITY ASSESSMENT IN EUROPEAN COUNTRIES

This research work examines levels and trends in global agricultural productivity in fifteen European Union countries and four Eastern European countries that have already applied for European Union membership. The study makes use of data collected from the Food and Agriculture Organization of the United Nations and covers the period 1980-1998. An approach based on Data Envelopment Analysis is used to provide information on the peers of the (inefficient) i-th country and to derive the Malmquist productivity indices. This approach is chosen due to the non-availability of reliable input price data to measure total factor productivity change, technical efficiency change and technical change. Model results show France, Bel-Lux and Italy are on the frontier...

Analysing Farmers' Decision-Making Process Face to the Mid-Term Review of the Common Agricultural Policy in the Alentejo region of Portugal

Palavras-chave: Productivity Analysis.

Ano: 2001

URL: http://purl.umn.edu/20696

This paper describes an experiment that was carried out in order to examine the decision making process of farmers in the Alentejo dryland region of Portugal. Cumulative Prospect Theory allows modeling the Alentejo dryland farmers' decision process, because when they decide what crops and livestock activities will produce the different results are appraised relatively to the initial wealth, which permits its appraisal in terms of gains and of losses. An inquiry is developed to study the Alentejo dryland farmers' preferences, which intend to determine risk preferences through a set of games. A discrete sequential stochastic programming model is developed to examine farmers' decision-making process face to the mid-term review of the Common Agricultural...

Assessment of Environment Impact of CAP Reforms on European Agricultural Production Efficiency

The studies of performance and production efficiency have ignored additional products of most transformation processes classified as undesirable outputs. Without the inclusion of the undesirable outputs, the efficiency measurement is a purely technical measure, and it does not account for the interaction of the system with the environment and the impact of policy decisions on the system. Moreover, there are technological dependencies between the desirable and the undesirable outputs which have to be included in the analytical tools used to measure efficiency. The relationships between the desirable and the undesirable outputs motivate the exploration of new areas of the measurement of efficiency to incorporate policy decisions and address new issues. This...

CUMULATIVE PROSPECT THEORY: A STUDY OF THE FARMERS' DECISION BEHAVIOR IN THE ALENTEJO DRYLAND REGION OF PORTUGAL

The mid-term review of the Common Agricultural Policy will change the way the European Union supports its farm sector. The new Common Agricultural Policy will be geared towards consumers, and taxpayers, while giving farmers the freedom to produce what the market wants. In the future, the majority of the subsidies will be paid independentlty from the volume of production. To avoid abandonment of production, Member States may choose to maintain a limited link between subsidy and production under well conditions and within clear limits. These new "single farm payment" will be linked to the respect of environmental, food safety and animal welfare standards. Severing the link between subsidies and production will make farmers more competitive and market...

ECONOMIC AND ENVIRONMENTAL IMPACTS OF THE POST-1992 CAP REFORMS ON ALENTEJO ECONOMY OF PORTUGAL

Palavras-chave: Farm Management.

Ano: 2004

URL: http://purl.umn.edu/20245

This research develops 'Johansen-type' models of agriculture and constructs Input-Output models for assessing the impact of the post-1992 CAP reforms on incomes, employment and the environment in four Alentejo study areas of Portugal. The effects of agricultural output changes on businesses supplying inputs and processing farm output were also assessed by those empirical models.

Influence of Political Campaign Contributions by American Agribusiness Firms on U.S. Farm Policy

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...

Measuring Eco-efficiency of Agricultural Activity in European Countries: A Malmquist Index Analysis

Palavras-chave: Agribusiness firm; Farm policy; Lobbying; Political contributions; Political Economy.

Ano: 2002

This paper develops an environmental performance index by applying the benefit of the doubt weighting and the Malmquist index concepts using Kuosmanen and Kortelainen’s approaches. The main difference between these approaches and other methods is that environmental performance is based on the definition of the eco-efficiency as the ratio of economic value added to the environmental damage index. The overall environmental performance index is also decomposed into two components representing changes due to technological progress (or regress) and due to changes in relative eco-efficiency. The dynamic environmental performance analysis is applied to 15 European agricultures from 1990 to 2004. Model results show that technical progress mostly explain...

Reallocating Agricultural Greenhouse Gas Emission in EU15 Countries

This research work uses an alternative approach for modeling agricultural greenhouse gas emissions as an undesirable output, based on the zero sum gains DEA model (ZSG-DEA BCC model). This approach reallocates agricultural greenhouse gas emissions among EU15 countries. The reallocation analysis of greenhouse gas emissions permits countries that increase their emissions negotiate the emissions reduction with the others. This negotiation process might create a quota trade system for agricultural activity.

This research develops a mathematical programming model to maximize the expected utility of the farmers' wealth-producing cereals in the Alentejo dryland region of Portugal, and it is used to determine the premium rate that crop farmers are willing to pay for reducing the variability of their incomes, and the Portuguese government subsidy of the premium rate in the case where the farmer is not willing to pay the totality of this.

The Role of area-yield crop insurance program face to the Mid-term Review of Common Agricultural Policy

Palavras-chave: Research Methods/ Statistical Methods; Risk and Uncertainty.

The mid-term review of Common Agricultural Policy increases the complexity of the decision-making process of farmers. The subsidies are substituted for a single decoupled income payment. The farmers decide what crops and livestock will produce based on climate, soils conditions and agricultural market signals and not based on subsidies granted to each one of the crop and livestock activities. The area-yield crop insurance program might have an important role on increasing production and facing natural catastrophes. This paper studies the introduction of the area-yield crop insurance program to reduce the risk originating from the variability of farmers' income and to compare this alternative with other agricultural policy alternatives in the context of...
