Última Farm-Level Evidence on the Sustainable Growth Paradigm from Grain and Livestock Farms AgEcon Escalante, Cesar L.; Turvey, Calum G.; Barry, Peter J.. This study uses the sustainable growth rate model to investigate, measure, and analyze sustainable growth rates and trends for Illinois farmers. Results of farm-level econometric analyses indicate the relevance of the sustainable growth paradigm in explaining most farm financial decisions made each year. Grain farms have shown a greater tendency to balance growth through adjustments in production efficiencies while livestock farms rely more on financial leveraging strategies. In general, our results have shown that the farm sector has adapted to positive or negative sustainable growth challenges consistent with the Higgins' model and that, from an equilibrium point of view, countercyclical measures of the sustainable growth challenge indicate that there...

Agricultural multifunctionality is the recognition of the joint exercise of economic, environmental and social functions by this sector. In order to make this concept operative for the design of public policies, it is necessary to estimate the social demand for such functions. The main objective of this article is to present an empirical application in this line. For this purpose we have taken the agricultural system of mountain olive groves in Andalusia (Southern Spain) at risk of abandonment after the decoupling of the EU subsidies as a case study. The economic valuation technique used is the Choice Experiment. According to the results, there is a different contribution of each attribute to the improvement of the Society level of utility. The main...

This paper analyzes how the market interventions of the Serbian government during the food crisis 2007/2008, inter alia a de facto export ban, have affected domestic wheat markets. Besides a comprehensive description of the crisis policy and its effects on the Serbian wheat market, we investigate how it influences the equilibrium and stability of the Serbian wheat market and its integration with the world market within a price transmission model. Applying a Markov-switching error correction model to weekly wheat grower prices in Serbia and world market prices, two states of the wheat market are identified. Our results suggest that although the long-run price elasticity did not change during the crisis, the market equilibrium was disrupted and the market...

Ano: 2011 URL: http://purl.umn.edu/114438 Organic certification systems and international trading of agricultural products in gravity models AgEcon Cantore, Nicola; Canavari, Maurizio; Pignatti, Erika. Recent literature about gravity models points out the importance of institutional frictions in the international market of agricultural products beyond the traditional economics variables as transport costs reducing the mass of trade in bilateral relationships. In particular, previous contributions stress that harmonization of food standards could decrease transaction costs in trading relationships by stimulating international market. In a previous work we hypothesized that the acknowledgment of equivalence in organic standards may represent a reliable signal of affinity in bilateral relationships which may be useful to identify areas in which transaction costs for both conventional and organic standards are lower. This article represents a step forward,...

Ano: 2011 URL: http://purl.umn.edu/98846 ECONOMIC EFFECTS OF A BAN AGAINST ANTIMICROBIAL DRUGS USED IN U.S. BEEF PRODUCTION AgEcon Mathews, Kenneth H., Jr.. Economic effects for three scenarios of antimicrobial drug use in livestock production -- a no-ban scenario and two levels of bans -- are examined through cost minimization and a partial equilibrium analysis. Results indicate that regulating antimicrobial drug use in livestock production would increase per-unit costs of producers previously using drugs and reduce beef supplies in the short run, reducing consumer surplus. Producers not previously using drugs would benefit from short-run price increases.

The study has analysed the temporary migration of sheep as a response to the demand-supply disequilibrium of fodder and water and has explored its trends, determinants and constraints by using the data collected from rural areas of semi-arid Rajasthan. About 32 per cent of the farmers in the study area undertake temporary sheep migration. The migrating farmers have higher holding size of sheep, goat and buffaloes and are better in terms of adoption of improved sheep management practices than non-migrant farmers. The flock size, potential household labour supply and credit absorption behaviour have been reported to positively affect the odds of migration. The farmers face various en-route problems during migration, the major ones being increased morbidity,...

We use two methodological approaches to analyze avian influenza related quarantine measures. First, a Heckman type gravity model is used to estimate the trade impact and second, a spatial partial equilibrium simulation model is developed to simulate welfare changes. The simulation model considers spread and transmission risk according to the disease status of the importing country as well as parameter uncertainty of the calibrated coefficients by using a Monte Carlo approach. The econometric results show that the principle of regionalization is preferred to import trade bans for uncooked meat. The simulation results verify the negative welfare impact of currently implemented regulatory policies and indicate that significant trade diversion effects...

Ano: 2012 URL: http://purl.umn.edu/122022 An Analysis of Latin American Peanut Trade AgEcon Lee, Dae-Seob; Kennedy, P. Lynn; Fletcher, Stanley M.. The U.S. export share in the world peanut market has decreased due to heavy competition. In this paper, the Latin American peanut industry is modeled using seemingly unrelated regression (SUR). Based on these estimations, a scenario analysis was conducted. The results show that the Latin American demand is not affected dramatically by either domestic of world price shocks. The effects of price changes on net trade are noticeable. However, the world price does not significantly affect the Latin American peanut supply. The results imply that Latin American peanut farmers are more sensitive to changes in domestic prices than world price changes.

Ano: 2006 URL: http://purl.umn.edu/43744 Border Effects on Spatial Price Transmission between Fresh Tomato Markets in Ghana and Burkina-Faso: Any Case for Promoting Trans-Border Trade in West Africa? AgEcon Amikuzuno, Joseph. Cross-border trade in food commodities within sub-regional economic blocks in Sub-Sahara Africa (SSA) is believed to be faster, cheaper, more convenient and welfare-enhancing than overseas trade between SSA countries and the USA, EU and the BRIC countries. The difficulty of commodity arbitrage across international borders SSA is however a fundamental constraint to price transmission, market integration and the realisation of the welfare-enhancing role of cross-border trade in Africa. This study examines the impact of border and distance on price transmission between tomato markets in Ghana and Burkina-Faso. The analysis applies a regime-switching vector error correction model to estimate semi-weekly, wholesale prices of tomato in four tomato markets in...

Ano: 2011 URL: http://purl.umn.edu/115519 The Impacts of Animal Disease Crises on the Korean Meat Market AgEcon Park, Moon-Soo; Jin, Yanhong H.; Bessler, David A.. Employing the error correction method and historical decomposition with direct acyclic graphs, we quantify the impacts of domestic and oversea animal disease crises on the Korean meat markets. We find that (a) the market partially recovered 16 months after the foot-and-mouth outbreak in 2000, and 13 months after the avian influenza and the U.S. BSE incidents in 2003; (b) animal disease outbreaks have differentiate impacts by disease type and supply chain level. Retailers likely to have windfall profits as the retail price margin increased relative to the farm and wholesale levels; and (c) disease outbreaks affect dynamic price interdependence.

This study analyses seafood consumption at home in Spain using three different cross-sectional survey data-sets for 1980, 1990 and 1998. Households are analysed in eleven different types, according to size and composition. Price indices for seafood and meats are calculated for each household type. Discrete participation and continuous consumption decisions are studied. Socio-economic variables sometimes play an important role but not with a regular pattern. Economic fundamentals follow a common pattern for all household types. Seafood demand is inelastic in 1980 and very elastic and meat complement in 1990 and 1998. Expenditure elasticity does not decrease between 1980 and 1998.

Ano: 2005 URL: http://purl.umn.edu/56078 Perspectives d’évolution des marches céréaliers pour la campagne de commercialisation 2005/06 AgEcon Diarra, Salifou Bakary; Dembele, Niama Nango. The 2005 – 2006 marketing campaign was difficult because of the drought that occurred in all countries in the region. As a result, the price of sorghum, millet, maize and rice soared. State actions to improve cereals supply through tax-exempt rice imports did not achieve the expected outcomes. Rice has been the main contributing factor to the rise of cereals price. The low levels of stocks of rice in the world and the supply in fertilizers below expectations along with a decrease in productivity have contributed to the rise of rice prices at the national level.

Ano: 1989 URL: http://purl.umn.edu/42288 ENSO AND SOYBEAN PRICES: CORRELATION WITHOUT CAUSALITY AgEcon Letson, David; McCullough, B.D.. In this paper we seek to characterize the robustness of the ENSO/soybean price relationship and to determine whether it has practical economic content. If such a meaningful relationship exists, the implications could be profound for commodity traders and for public sector investments in climate forecasting capabilities. Also, the validity of economic evaluations of climate impacts and climate forecasts based on ENSO-price independence would come into question. Our findings suggest a relationship between interannual climate and soybean prices, although we are not able to attribute the relationship to ENSO or to say the ENSO is economically important.

Ano: 2009 URL: http://purl.umn.edu/108258 The Effect of Increased Energy Prices on Agriculture: A Differential Supply Approach AgEcon Moss, Charles B.; Livanis, Grigorios T.; Schmitz, Andrew. The increase in energy prices between 2004 and 2007 has several potential consequences for aggregate agriculture in the U.S. We estimate the derived input demand elasticities for energy as well as capital, labor, and materials using the differential supply formulation. Given that the derived input demand for energy is inelastic, it is more price-responsive than the other inputs. The results also indicate that the U.S. aggregate agricultural supply function is responsive to energy prices.

Ano: 2010 URL: http://purl.umn.edu/100514 Impact of Beef Quality on Market Signals Transmitted by Grid Pricing AgEcon Johnson, Heather C.; Ward, Clement E.. Value-based marketing is shaping cattle production; however, market signals differ dramatically depending on carcass quality. This study applies a two-stage coefficients of separate determination procedure to four regional fed cattle datasets sorted by grid value and by carcass quality attributes. Weight is the strongest signal sent when higher valued cattle and better quality cattle are sold on a grid. Quality characteristics send stronger signals when lower valued cattle and poorer quality cattle are sold on a grid. Producers of lower quality cattle can potentially gain $52 to $149 per head by improving quality and $113 to $150 per head by adding weight.
