Dynamic and Asymmetric Adjustment in Beef and Pork Prices AgEcon
Hahn, William F..
Beef and pork prices at farm, wholesale and retail are examined for evidence of a dynamic and asymmetric price transmission using an endogenous switching model. Dynamic adjustment means that it take time for prices to adjust to changes in the market. Price transmission is asymmetric if the speed or completeness of price adjustment depends on the direction that the price or a related price is moving. Some of the previous research on price transmission in agricultural markets attempts to use market power abuses as an explanation of price-transmission asymmetry. Other research shows that price transmission asymmetry can arise in competitive markets and that competitive and anti-competitive issues can make prices adjust faster upwards or downwards. By...

Pesticides Uses in Crop Production: What Can We Learn from French Farmers Practices? AgEcon
Fadhuile, Adelaide; Lemarie, Stephane; Pirotte, Alain.
This article focuses on the demand system of French farmers concerning pesticides uses. We estimate the demand elasticities of herbicides, insecticides and fungicides with respect to pesticide expenditure, and considering crop differentiation. Then we compare two indexes that are used in agronomic literature to measure the intensity of pesticides uses. We retain a Linear Approximated Almost Ideal Demand System (LA/AIDS) specification. A Full-Information Maximum Likelihood estimation procedure is used for dealing with the problem of censored dependent variable. We consider two cross-sections observed in 2001 and 2006 covering pesticides uses of three crops. We confirm the previous results of the literature that farmers response to price variation is very...

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.

PRICE REACTIONS AND ORGANIC PRICE PREMIUMS FOR PRIVATE LABEL AND BRANDED MILK AgEcon
Zhuang, Yan; Dimitri, Carolyn; Jaenicke, Edward C..
Using Nielsen Homescan data set from 52 markets in the United States, this paper assesses the price interactions among the four fluid milk categories (organic private label, organic national brand, non-organic private label and non-organic national brand), how demographic variables and product properties in a market affect milk prices, and the impacts of private label and organic milk market shares on milk prices. We find several types of price competition exist among the four milk categories, including for example symmetric cooperative (non-organic private label vs. non-organic branded milk) and asymmetric dominant-fringe (both organic branded vs. organic private label and non-organic national brand vs. organic national brand. We also find that the...

Determinants of Romanian Farmers' Participation in Agri-Environmental Programmes AgEcon
Toma, Luiza; Mathijs, Erik.
The paper aims to identify the factors underlying farmers' propensity to participate in agri-environmental programmes in a Romanian rural region that confronts non-point source pollution. For this, we employ structural equation modelling with latent variables using data collected through an agri-environmental farm survey in 2001. The model includes one 'behavioural intention' latent variable ('propensity to participate in agri-environmental programmes') and five 'attitude' and 'socioeconomic' latent variables ('demo-social characteristics', 'economic characteristics', 'agri-environmental information access', 'environmental risk perception' and 'general environmental concern'). The results indicate 'environmental risk perception' as the strongest...

A Hedonic Metric Approach to Estimating the Demand for Differentiated Products: An Application to Retail Milk Demand AgEcon
Gulseven, Osman; Wohlgenant, Michael K..
This article introduces the Hedonic Metric (HM) approach as an original method to model the demand for differentiated products. Using this approach, initially we create an n-dimensional hedonic space based on the characteristic information available to consumers. Next, we allocate products into this space and estimate the elasticities using distances. What distinguishes our model from traditional demand models such as Almost Ideal Demand System (AIDS) and Rotterdam Model is the way we link elasticities with product characteristics. Moreover, our model significantly reduces the number of parameters to be estimated, thereby making it possible to estimate large number of differentiated products in a single demand system. We applied our model to estimate the...

Imposing Curvature Conditions on Flexible Functional Forms to GNP Functions AgEcon
Chapda Nana, Guy; Larue, Bruno.
This paper empirically investigates the implications of the imposition of convexity in output prices and concavity in factor endowments on flexible functional forms for the GNP function. Using macroeconomic data for Switzerland, we estimate the Translog and the Symmetric Normalized Quadratic forms to investigate the manner with which curvature restrictions are imposed, the extend of curvature violations and the robustness of estimated elasticities. We also compare the predictive accuracy of the aforementioned flexible functional forms. Our result show that concavity in factor endowments is violated much more often than convexity in output prices. For the Translog, the date at which local restrictions are imposed matters a great deal in terms of remaining...

Effects of Taxing Sugar-Sweetened Beverage and Subsidizing Milk: Beverage Consumption, Nutrition, and Obesity among US Children AgEcon
Lin, Biing-Hwan; Smith, Travis A.; Lee, Jonq-Ying.
Taxing sugar-sweetened beverages (SSBs) has been proposed as a means to improve U.S. diet and health and generate revenue to address obesity-related issues. A related concern is that children’s intake of SSBs, a third that of milk consumption in the late 1970s, now equals milk consumption. Displacing milk by SSBs may shortchange the buildup of bone mass, increasing the risk of fractures and osteoporosis in later life. Accordingly, we examine the effects that a 20- percent SSB tax and a 20-percent milk price subsidy would have on the diet and health of American children. We estimated US beverage demand systems and used the estimated demand elasticities to examine the impacts of the hypothetical SSB tax and milk subsidy. Our results suggest that a 20-percent...

Elasticities for U.S. Wheat Food Use by Class AgEcon
Marsh, Thomas L..
We conceptualize wheat for food use as an input into flour production and derive demand functions to quantify price responsiveness and economic substitutability across wheat classes. Cost, price, and substitution elasticities are estimated for hard red winter, hard red spring, soft red wheat, soft white winter, and durum wheat. In general, hard red winter and spring wheat varieties are much more responsive to their own price than are soft wheat varieties and durum wheat. Morishima elasticities indicate that hard red winter and hard red spring wheat are economic substitutes for milling purposes.
