The Price of Happy Hens: A Hedonic Analysis of Retail Egg Prices AgEcon
Chang, Jae Bong; Lusk, Jayson L.; Norwood, F. Bailey.
This paper analyzes price differentials among conventional, cage-free, organic, and Omega-3 eggs using retail scanner data from two regional markets and the United States as a whole. Results reveal significant premiums attributable to cage-free (a 57% premium on average) and organic (an 85% premium on average). However, significant variation exists among geographic locations; price premiums for organic over conventional eggs in Dallas are almost twice as high as those in San Francisco. Estimates indicate that about 42% of the typically observed premium for cage-free eggs over conventional eggs (and 36% of the premium for organic eggs) can be attributed to egg color rather than differences in hens’ living conditions. Despite the large implicit price...

The Relative Importance of Preferences for Country-of-Origin in China, France, Niger and the United States AgEcon
Ehmke, Mariah D.; Lusk, Jayson L.; Tyner, Wallace E..
Country-of-origin (COO) is an increasingly politicized credence attribute in the globalizing food system. While international policy development in this area is geographically far-reaching, the benefits of country-of-origin labels (COOL) to producers and consumers from countries in different locations and levels of economic development are not clear. Previous work investigates the importance of COO to consumers, but is typically limited in scope to consumers in one nation. In addition, little is known about the importance of COO information relative to other credence attributes, especially in non-meat food products. This study measures the benefits of COOL to an internationally diverse set of consumers (in developed and developing countries) and estimates...

The Relative Importance of Search versus Credence Product Attributes: Organic and Locally Grown AgEcon
Wirth, Ferdinand F.; Stanton, John L.; Wiley, James B..
Organic foods and local foods have come to the forefront of consumer issues, due to concerns about nutrition, health, sustainability, and food safety. A conjoint analysis experiment quantified the relative importance of, and trade-offs between, apple search and experience attributes (quality/blemishes, size, flavor), credence attributes (conventional vs. organic production method, local origin vs. product of USA vs. imported), and purchase price when buying apples. Quality is the most important apple attribute. Production method—organic versus conventional—had no significant impact on preferences.

The Structure and Profitability of Organic Field Crop Production: The Case of Wheat AgEcon
McBride, William D.; Greene, Catherine R.; Ali, Mir B.; Foreman, Linda F..
Results from long-term experimental trials suggest that similar yields and lower costs are possible from organic compared with conventional field crop production, but there is little information about the relative costs and returns on commercial farms. This study examines the structure and profitability of commercial wheat production using a nationwide survey of wheat producers for 2009 that includes a targeted sample of organic growers. Treatment-effect models were specified to isolate the impact of choosing the organic approach on various levels of wheat production costs. Average organic wheat yields were much lower than for conventional wheat, but per acre operating plus capital costs were also lower. Estimated operating costs per bushel for organic...

Uncertainty in Spanish Organic Products: A Global Analysis from Consumer to Entrepreneurs AgEcon
Briz, Teresa; de Felipe, Isabel.
The organic market is a very particular one. Starting from the premise that organic products are confidence and credibility products which cannot be easily differentiated from the rest, we find that consumers face a risk when purchasing them. In Spain, the marketing chain does not follow the conventional stages in most of the cases, so there is always some uncertainty about how the products will be sold. In addition, the great majority of the Spanish organic production is marketed abroad. In this paper we show some of the results of an investigation project in this topic.

Vertical Economies of Scope for Organic and Conventional Dairy Farms in the United States AgEcon
Mayen, Carlos D.; Balagtas, Joseph Valdes; Alexander, Corinne E..
Studies of dairy farm structure have neglected issues of vertical organization of the farm. In this study we model and measure the potential for dairy farms to reduce costs of production through vertical integration. We estimate a multi-stage, multi-output cost function to assess vertical economies of scope in organic and conventional dairy farms. We model the cost of producing grains and forages, which are then used as inputs in the production of milk. We find negligible vertical economies of scope for conventional dairy farms. In contrast, we find significant vertical economies of scope in organic dairy production, suggesting that there is an economic incentive for vertical integration into feed production. The large vertical economies of scope for...

What Affects Consumption Patterns of Organic and Conventional Products? AgEcon
Grebitus, Carola; Yue, Chengyan; Bruhn, Maike; Jensen, Helen H..
Consumers show an increased interest in organic food today and a willingness to pay premium for organic products. In addition to price, changing attitudes and beliefs about food quality affect food choice. This article analyses the impact of attitudes, quality characteristics and socio-demographics on consumption of organic and conventional pork, potatoes and milk. The concept of ‘perceived quality’ provides the theoretical background. The data come from a consumer survey conducted in Germany in 2004 (n=260). An ordered logit model was used for analysing the data. We observe clear differences in consumers’ use of certain quality characteristics as they perceive and evaluate conventional and organic fresh foods.

What is the Difference in Profit per Acre between Organic and Conventional Coffee? AgEcon
Jensen, Jennifer; Dicks, Michael R..
The research addresses the economic problem of deforestation. A contributing factor to deforestation is coffee production. Coffee is an indigenous plant that is naturally occurring in the native tropical forests. However, conventional coffee is grown on cleared forest soil. In the native forest there is the potential for additional fruits (bananas, mangoes, avocados) and wood products while in the conventional coffee production system the only product is coffee. Conventional coffee production often causes deforestation and soil erosion while the organic coffee production system does not. In addition, the price risk associated with the coffee monoculture is high and has proven disastrous to the sustainability of coffee production in past years. Thus,...
