Analyse de la Reponse de l'offre des Pommes en Tunisie : Une Approche Econometrique AgEcon
Laajimi, Abderraouf; Guesmi, Anis; Dhehibi, Boubaker.
In Tunisia, the apples occupy a significant place on the sector of perennial crops. This crop covered expanded areas during the eighties following an extensive use of efficient water equipments. However, significant seasonal and annual variation of fruit supplies in the domestic market were frequently encountered affecting prices at both wholesale and consumption levels. To study the supply response of apples we carried out an econometric estimate of the model of supply response. Modelling was carried out in two stages: determination of the variation of the surfaces, on the basis of equation of news plantations and the equation of removals, and the variation of yields. The methodological approach that we followed takes account of the characteristics and...

Analyzing supply response of fruit tree products in Tunisia: The case of peaches AgEcon
Laajimi, Abderraouf; Guesmi, Anis; Mahfoudhi, A.; Dhehibi, Boubaker.
In Tunisia, peaches have a significant place in the fruit tree sector. Planted areas have been expanding ever since the eighties as a result of irrigation water extension and the use of better yielding varieties. These factors resulted in high production levels and fruit exports thereof. However, important seasonal and annual variation of fruit supplies continues to characterize prices at both wholesale and consumption levels. To study the response of peach production an econometric model was developed. Modelling was carried out in two stages. First area variation was explained through new plantings and removals and second yield variation was analyzed. The methodological approach followed takes into account the characteristics and...

Do Decoupled Payments Stimulate Production? Estimating the Effect on Program Crop Acreage Using Matching AgEcon
Key, Nigel D.; Roberts, Robert J..
This study uses matching to evaluate the effect of decoupled payments on the acreage response of Iowa farmers who were in business in 1997 and 2002. Using farm-level panel data from the U.S. Agricultural Census, we examine whether farmers receiving high levels of 1997 agricultural payments per acre had a greater increase in program crop acreage between 1997 and 2002 than farmers receiving low levels of payments. The panel data set allows for conditioning current acreage on past individual acreage and operator characteristics. The large and exhaustive sample allows for comparisons across similar farms. The matching methodology avoids distributional and functional form assumptions about the relationship between the treatment and outcome. Results are...

Economic Assessment of Hazelnut Production and the Importance of Supply Management Approaches in Turkey JARTS
Gönenc, Sertac; Department of Agricultural Economics, Agricultural Faculty, Uludag University, 16059, Gorukle, Bursa, Turkey; Tel: +90 224 442 89 70 (283), Fax: +90 224 442 80 77, e-mail: sduman@uludag.edu.tr; Tanrıvermis, Harun; Department of Agricultural Economics, Agricultural Faculty, Ankara University, Diskapi, Ankara, Turkey, e-mail: tanriver@agri.ankara.edu.tr; Bülbül, Mehmet; Department of Agricultural Economics, Agricultural Faculty, Ankara University, Diskapi, Ankara, Turkey, e-mail: bulbul@agri.ankara.edu.tr.
Turkey is the world’s leading producer accounting for about 70% of world hazelnut supply. Hazelnut production is the single most important economic activity (monoculture) and income resource of rural households in the Black Sea Region. Hazelnut sector is supporting since 1962. However, due to inappropriate policies a stock problem has arisen in the sector. The Government has intervened to over production problem with various regulatory measures since 1989. However, results of supply response model showed that legal regulations have not any significant effect on reducing over production. Annual rate of increase of hazelnut production was calculated as 4.48%. And long term supply elasticity was found as 0.09 by Nerlove Model. The inelastic supply...

Effects of Japanese Import Demand on U.S. Livestock Prices: Comment AgEcon
Kinnucan, Henry W..
A recent study of Miljkovic, Marsh, and Brester estimates that reductions in the Japanese tariff-rate quota between 1993 and 2001 increased U.S. beef prices by $1.03 per cwt and yen depreciation between 1995 and 1998 reduced U.S. hog prices by $0.99 per cwt. Relaxing the assumption that U.S. beef and hog supplies are fixed cuts the total elasticities underlying these estimates by 50% or more. The upshot is that shocks in the Japanese market have little effect on U.S. beef and pork prices. Hence, producers may be better off focusing on domestic issues such as dietary concerns over red meat consumption.

Effects of Japanese Import Demand on U.S. Livestock Prices: Reply AgEcon
Miljkovic, Dragan; Marsh, John M.; Brester, Gary W..
In responding to a comment article, we concur that quantifying U.S. livestock price response to changing Japanese met import demand requires nonzero supply elasticities beyond one quarter. However, rigidities in market trade and empirical tests justify the inclusion of exchange rates in the short-run analysis. Producer welfare asymptotically approaches zero for increasing supply elasticities in the long run, but short-run transitions in producer surplus are meaningful to producers.

Effects of Marketing Loans on U.S. Dry Peas and Lentils: Supply Response and World Trade AgEcon
Lin, William W.; Lucier, Gary.
The 2002 Farm Act required USDA to implement marketing loans for the 2002-07 crops of dry peas, lentils, and small chickpeas. This provision led to expanded acreage for dry peas and lentils, crops analyzed in this study. The analysis found that marketing loans played a role in expansion for dry peas in 2003-05 and for lentils in 2003. For dry peas and lentils, marketing loans contributed to acreage expansion in North Dakota and Montana. Simulation model results suggest that marketing loans had negligible impacts on world prices for dry peas and lentils in 2003-05. Impacts on U.S. exports were minor, increasing by about 2 percent in 2003.

Empirical investigation of investment behaviour in Australia's pastoral region AgEcon
Agbola, Frank W.; Harrison, Stephen R..
Optimal intertemporal investment behaviour ofAustralian pastoralists is modelled using panel data for the period 1979–1993.Results indicate that quasi-fixity of inputs of labour, capital, sheep numbers and cattle numbers is characteristic of production in the pastoral region. It takes about two years for labour, four years for capital and a little over two years for both sheep numbers and cattle numbers to adjust towards long-run optimal levels. Results also indicate that, after accounting for adjustment costs, own-price product supply and input demand responses are inelastic in both the short and long run.

Farmers' Subjective Valuation of Subsistence Crops: The Case of Traditional Maize in Mexico AgEcon
Arslan, Aslihan; Taylor, J. Edward.
Shadow prices guide farmers' resource allocations, but for subsistence farmers growing traditional crops, shadow prices may bear little relationship with market prices. We econometrically estimate shadow prices of maize using data from a nationally representative survey of rural households in Mexico. Shadow prices are significantly higher than the market price for traditional but not improved maize varieties. They are particularly high in the indigenous areas of southern and southeastern Mexico, indicating large de facto incentives to maintain traditional maize there.

How Much Do Decoupled Payments Affect Production? An Instrumental Variable Approach with Panel Data AgEcon
Weber, Jeremy G.; Key, Nigel D..
Agricultural support payments that cause no or minimal production distortions are exempt from World Trade Organization restrictions. If and how much decoupled payments, such as direct payments in the U.S., affect agricultural production remains an open empirical question with implications for policy. We use multiple years of the Census of Agriculture to estimate the aggregate supply response to changes in direct payments. To identify an exogenous source of variation in payments we exploit a provision of the 2002 Farm Act that departed from previous policy by making oilseeds eligible for direct payments, thus increasing payments to areas that historically produced more oilseeds. Using a sample of ZIP codes that accounts for more than eighty percent of the...

Incentives to Supply Enhanced Ecosystem Services from Cropland AgEcon
Jolejole, Christina B.; Swinton, Scott M.; Lupi, Frank.
This paper examines the willingness of farmers to participate in hypothetical programs that would pay them to adopt cropping practices that enhance provision of ecosystem services from agriculture. A survey of 3,000 Michigan corn and soybean farmers elicited willingness to adopt four sets of cropping practices that reflected increasing levels of environmental stewardship. Acreage enrollments in the programs were modeled using hurdle models. The acreage that farmers would be willing to enroll depends chiefly on farm size and the perception of environmental improvements from the practices. For farms over 500 acres, the payment offered was also a significant inducement to acreage enrollment in all systems examined. This paper advances the literature on...

Issues and Strategies for Aggregate Supply Response Estimation for Policy Analyses AgEcon
Ramirez, Octavio A.; Mohanty, Samarendu; Carpio, Carlos E.; Denning, Megan.
We demonstrate the use of the small-sample econometrics principles and strategies to come up with reliable yield and acreage models for policy analyses. We focus on demonstrating the importance of proper representation of systematic and random components of the model for improving forecasting precision along with more reliable confidence intervals for the forecasts. A probability distribution function modeling approach, which has been shown to provide more reliable confidence intervals for the dependent variable forecasts than the standard models that assume error term normality, is used to estimate cotton supply response in the Southeastern United States.

Projecting Livestock Numbers AgEcon
Forbes, Rod; Gardiner, Peter.
The Ministry of Agriculture and Forestry (MAF) undertakes forecasts and projections of livestock numbers as part of the twice yearly contribution to The Treasury’s economic and fiscal updates. MAF’s Pastoral Supply Response Model (PSRM) was recently re-developed and used for the first time in the Budget Economic and Fiscal Update round of 2004. The PSRM projects annual inventory numbers as at 30 June, births and livestock numbers for slaughter. The paper discusses the PSRM, the post-model adjustments process, and the feed through to a simplistic assessment of land use changes within pasture areas.

SOURCES OF GROWTH AND SUPPLY RESPONSE: A CROSS-COMMODITY ANALYSIS OF CHINA'S GRAIN SECTOR AgEcon
Colby, Hunter; Diao, Xinshen; Somwaru, Agapi.
A growth accounting method is used to analyze the sources of growth in China's rice, wheat, corn and soybeans, the four most important crops in China's grain sector, during 1978-97. A large TFP contribution to growth in grain production is found in the period immediately following China's rural economic reform (1978-85). In recent years the growth rate of TFP falls sharply, contributing less than 20 percent of growth in grain production, as increased use of inputs became the major engine of growth. If the current government policy environment remains unchanged, China's grain production will become increasingly costly and constrain future growth and competitiveness in world grain markets. The supply response of the four grains is estimated using a...

Supply response on the Hungarian pork meat sector AgEcon
Bakucs, Lajos Zoltan; Markus, Richard.
Despite of the increasing production and consumption of white meats, pig breeding is still one of the most important animal husbandry sectors Worldwide and in the European Union as well. In Hungary over the past decades, the pig sector has undergone significant changes. The livestock has sharply decreased from more than 8.5 million in 1989 to 3.3 million in present. After the post 1989 increase of herd size bred in family farms, their share diminished, at present two-thirds of output is produced by corporate farms. It appears that small scale farming has major difficulties, they must consider all cost reducing alternatives to improve their competitiveness. With pressure on purchase prices from the downstream market levels, and considering that fodder...

SUPPLY RESPONSE UNDER THE 1996 FARM ACT AND IMPLICATIONS FOR THE U.S. FIELD CROPS SECTOR AgEcon
Torre Ugarte, Daniel de la; Sanford, Scott; Skinner, Robert A.; Westcott, Paul C.; Lin, William W..
The 1996 Farm Act gives farmers almost complete planting flexibility, allowing producers to respond to price changes to a greater extent than they had under previous legislation. This study measures supply responsiveness for major field crops to changes in their own prices and in prices for competing crops and indicates significant increases in responsiveness. Relative to 1986-90, the percentage increases in the responsiveness of U.S. plantings of major field crops to a 1-percent change in their own prices are wheat (1.2 percent), corn (41.6 percent), soybeans (13.5 percent), and cotton (7.9 percent). In percentage terms, the increases in the responsiveness generally become greater with respect to competing crops' price changes. The 1996 legislation has...

The Common Agricultural Policy and EU Enlargement: Implications for Agricultural Production in the Central and Eastern European Countries AgEcon
Fernandez, Javier.
This paper focuses on the consequences that an extension of the Common Agricultural Policy could have on agricultural production in the Central and Eastern European Countries. It reviews the evidence presented by recent attempts to quantify the potential impacts of accession on production levels in the CEECs. It also takes into account results from previous studies in order to analyse the importance that structural constraints might have on the capacity of the CEECs' agricultural sectors to respond to supply incentives under accession to the EU, and to examine some research questions that are still unanswered in relation to the supply potential of the CEECs. Some conclusions and policy recommendations are drawn at the end.

THE 'MILK QUOTAS RENT PUZZLE' IN THE EU: ECONOMIC SIGNIFICANCE, REVIEW, AND POLICY RELEVANCE AgEcon
Jongeneel, Roelof A.; Tonini, Axel.
In the so-called Common Agricultural Policy (CAP) 'Health Check' the European Commission has recently proposed gradual transitional measures to allow a 'soft landing' of the milk sector to quota expiry. The aim of this paper is to support policy makers to get better insights in the implications of some of the most important economic assumptions and empirical choices made in partial equilibrium models focusing on dairy. Three partial equilibrium models are considered: the Agricultural Member states MODeling (AGMEMOD) model, the Common Agricultural Policy SIMulation (CAPSIM) model, and the European Dairy Industry Model (EDIM). The paper analyzes how the most important economic supply components, as they are part of the three key dairy models, affect milk...

Valuing options for reserve water in the Fitzroy Basin AgEcon
Rolfe, John; Windle, Jill.
Option values may be an important component of non-use values when development options for environmental assets are considered. These are values that the community might hold for maintaining options to make future choices about allocating resources. However, option values are very difficult to define, at both theoretical and practical levels, and there has been a retreat over the past decade to the more inclusive concept of option prices. In the present paper, estimates of option values are reported for retaining unallocated water in reserve rather than using it for current development. The use of option values rather than option prices is justified on the basis that the focus is on nonuse values, and demand and supply uncertainties have been minimised....
