  The growing importance of economic factors in farmers` decisions to go organic has raised interest in characterizing the economic behavior of organic versus conventional farms. In general, published analyses so far have not considered differential uncertainties, abilities to control production risk, and farmers` risk preferences between conventional and organic practices when comparing these techniques. Our article attempts to assess this issue. We use a model of farmer decision under risk to analyze the differential values between organic and conventional Spanish arable crop farms and to assess the incentives for adoption of organic practices. Results show that organic and conventional farms do have different production risks as well as different aversions to risk. Organic price premiums and subsidies are found to be powerful instruments to motivate adoption of organic techniques.

  We use a smooth transition vector error correction model to assess price relationships within the U.S. ethanol industry. Monthly ethanol, corn, oil, and gasoline prices from 1990 to 2008 are used in the analysis. Results indicate the existence of long-run relationships among the prices analyzed. Strong links between energy and food prices are identified.

  Using survey data collected in multiple locations (California and Texas in the United States and Revohot in Israel), we quantify category- and location-specific variations of consumers’ willingness to pay (WTP) for brand products after controlling for consumer characteristics. We find that consumers have a similar qualitative assessment of brand value in different product categories across different locations. That is, consumers have a stronger preference and higher WTP for brands in consumer electronics, followed by clothing and then processed food, and the lowest in fresh produce. Furthermore, we simulate price premiums and market shares of brands relative to generic products in different categories. Simulation results suggest that brands in fresh produce have the highest price premium but lowest market share. Despite the similarities, the magnitude of WTP for brands as well as the simulated price premium and the corresponding market share in the same product category are location variant. The similarities and dissimilarities suggest validity of having global brand strategies adapted to local conditions, that is, the so-called “thinking globally and acting locally” strategy.

  Using random effects and mixed effects probit regression techniques, this empirical study investigates factors for technology adoption at the firm level. We account for problems of sequential technology implementation and behavior identification. Results underscore the importance of risks faced by the agents, the effects of network externalities and peer-group learning, and the positive influence of previous firm-specific innovation experiences.

  This article presents results of a field experiment designed to assess willingness to pay for safely produced free-range chicken in Hanoi, the capital of Vietnam. Improved safety of chicken production and trading is suggested as an important component of avian influenza control strategy, which aims to address the direct costs of avian influenza as well as the global public health externality. However, consumer demand for safely produced free-range chicken is unknown. Products that have credible food labeling are not common in traditional markets where the majority of free-range chicken is purchased. Valuing characteristics of products sold in informal markets is a major challenge that our experiment overcomes. As part of the experiment, we provided several vendors from these markets with safety-labeled free-range chicken. Consumer valuation of safety labeling was elicited through having experiment participants, who were representative of potential consumers, select between discount coupons for either safety-labeled chicken or regular chicken. Results indicate that consumers will pay at least $0.50, or a 10–15% premium, per chicken purchase for safety labeling, which emphasizes safe production, processing, and transport conditions. This premium is smaller than the premium currently paid for traditional chicken varieties that are considered to be tastier. Consumers with more education have higher valuation of safety labeling. Hence, safety labeling for high-quality free-range chicken can play a role in controlling livestock disease and improving public health.
