A stochastic grain production frontier model is estimated on a representative sample of Ukrainian state farms. Technical inefficiency effects are modeled as a function of workforce composition, other farm-specific variables, and time. Technical inefficiency increased over time. Investment in farm infrastructure is associated with higher levels of technical efficiency.

Evidence from recent U.S. food consumption surveys provides new information on the distribution of rice consumption, the characteristics of rice consumers, and the diets of people who consume rice. Recently available data from nationally representative surveys of food consumed by individuals in the United States allowed comparison of consumption today (2001-02) with consumption in the mid-1990s. Data come from the Continuing Survey of Food Intakes by Individuals (1994-96) and the National Health and Nutrition Examination Survey (2001-02). Rice is consumed by a significant portion of the U.S. adult population. In 2001-02, over 18 percent (18.2 percent) of adults reported eating at least half a serving of white or brown rice in one day of observed intake....

Childhood and adolescence are unique periods of growth and development. In addition to maturing physically, children begin to make independent choices about when, where, and what they eat. Good nutrition during childhood and adolescence plays a key role in assuring adequate growth and development, preventing the long-term risk of chronic disease, and enhancing health and well-being. The U.S. Department of Agriculture’s (USDA) school meal programs play an important role in children’s diets and can thus influence their weight status and health. On average, children obtain more than one third of their daily energy intake from meals consumed at school during the school year (Briefel et al 2009). The National School Lunch Program (NSLP) is one of the largest...

Hypothetical bias is a persistent problem in stated preference studies. We propose and test a method for reducing hypothetical bias based on the cognitive dissonance literature in social psychology. A central element of this literature is that people prefer not to take inconsistent stands and will change their attitudes and behavior to make them consistent. We find that participants in a stated preference willingness-to-pay study, when told that a nonhypothetical study of similar goods would follow, state significantly lower willingness to pay than participants not so informed. In other words, participants adjust their stated willingness to pay to avoid cognitive dissonance from taking inconsistent stands on their willingness to pay for the good being...

The popularity of AIDS may not easily extend to censored demand systems. We propose an incomplete demand system that has relatively few restrictions on the parameter space, but preserves its theoretical consistency and apply this model to Indonesian data that have significant proportion of censored observations.

When using household-level data to examine consumer demand it is common to find that consumers purchase only a subset of the available goods, setting the demand for the remaining goods to zero. Ignoring such censoring of the dependent variables can lead to estimators with poor statistical properties and estimates that lead to poor policy decisions. In this paper we investigate household demand for four types of breakfast cereals, such as whole grain ready-to-eat, non-whole grain ready-to-eat, whole grain hot and non-whole grain hot cereals, using a censored Al- most Ideal Demand System (AIDS) and estimate the parameters of the model via Bayesian methods. Using household level scanner data (ACNielsen Homescan) we find that demand for all types of breakfast...

A stochastic production frontier model with technical inefficiency effects is estimated on a representative sample of Ukrainian state and collective grain-producing farms. Technical efficiency declined from 1989 to 1992. More experienced managers were found to be more productive, with the effect of experience diminishing with age. We found that on-farm provision of production infrastructure was associated with higher efficiency, a result supporting the hypothesis that disorganization causes output to decline in transition economies.

A theoretically consistent incomplete demand system is estimated to quantify the cost of the 1997 microeconomic crisis. Welfare cost per person was $128, which translates to $26.12 billion total cost. This amount is equivalent to agriculture's GDP contribution, and sufficient to pay for Indonesia's total annual government budget.

The structure of the pork production, slaughter, and processing sectors in Mexico has changed significantly since implementation of the North American Free Trade Agreement (NAFTA) and with rising income and increased urbanization. Today, Mexico's pork industry has become more integrated and achieved greater production efficiencies in response to increasing demand for better product quality and stricter sanitary practices in production and processing pork for both the domestic market and for export. However, despite these improvements Mexico's pork industry has not kept up with the rising domestic demand, and Mexico has become an increasingly important market for the United States. A key to the development of increased trade in both live animals and pork...

Problems of overweight and obesity among children have increased in China and pose a problem both for individuals as well as for public social and health care systems. This study explores factors contributing to weight problems among children age 6 to 18 years old in urban China. Data come from the 2004 China Health and Nutrition Survey. Results from a binary probit model show that parents' being overweight, some patterns of TV use, and more frequent eating in fast food restaurants influence children being overweight. Among younger children, parent's dietary knowledge was a significant factor. For adolescents, TV habits and concern about being liked by friends were significant. The results suggest that targeted nutrition education, especially for parents...

The economic efficiency of Indonesian rice farmers was lower and more variable during than before the macroeconomic crisis. Specifically, larger declines in technical efficiency were not offset by smaller improvements in allocative efficiency. Farm ownership, larger farm size, and higher education were associated with higher levels of efficiency.

This study examines the interaction between Food Stamp Program (FSP) and Temporary Assistance for Needy Families (TANF) program participation, provides a model of joint decisions made by households on FSP, TANF, and labor force participation, and explains why households choose different alternatives. We use the first Survey of Program Dynamics (SPD) longitudinal data and the 1998 SPD experimental data files. The modeling component consists of estimating equations to predict the probability of particular choices made by households. The households choose the alternative that gives the highest utility. The results show that the program parameters do matter. Variations across states in payment standards, benefit reduction rates, and income disregards help to...

The linear approximate version of the AIDS model is estimated using data from the Lithuanian household budget survey covering the period from July 1992 to December 1994. Price and real expenditure elasticities for twelve food groups were estimated based on the estimated coefficients of the model. Very little or nothing is known about the demand parameters of Lithuania and other former socialist countries, so the results are of intrinsic interest. Estimated expenditure elasticities were positive and statistically significant for all food groups while all own-price elasticities were negative and statistically significant, except for that of eggs which was insignificant. Results suggest that Lithuanian household consumption did respond to price and real...

Antibiotic drugs are currently used in 90 percent of starter feeds, 75 percent of grower feeds, more than 50 percent of finishing feeds and at least 20 percent of sow feeds (USDA/APHIS). A ban on the use of feed-grade antibiotics would lead to changes in production processes and practices in production of pork, and hence would have an economic impact on the U.S. pork industry and pork market. This study considers the economic effects of a ban in pork production, with no change of regulation on other meats. The analysis uses a set of technical assumptions that are based in large part on a historical analysis of how the Swedish ban influenced the Swedish pork industry to anticipate the potential economic effects. A range of cases is examined. The cases use...

In producing potatoes the treatment for disease and pests could be more difficult and costly for organic producers than for conventional. Hence, consumers’ attitudes and willingness to pay for organic potatoes need to be considered in a grower’s choice of production technologies. A bivariate probit model and cluster analysis were applied to survey data to evaluate factors that influenced Germany consumers’ consumption patterns for conventional and organic potatoes. The results show that consumers associate organic potatoes with healthy ingredients, trustable origin and food safety. But a lack of varieties and inferior appearance of organic potatoes limit consumer interest in the organic products. With regard to socio-demographics, consumers with higher...

As public and private demand for food safety grows, firms need to be able to evaluate the optimal (least-cost) combinations of interventions to reduce pathogens. We use data from input suppliers to hog packing firms and from meat science studies to examine the cost function for pathogen reduction. An economic optimization model is used to explore the trade offs in achieving multiple pathogen reduction targets. Our data indicate costs of individual pathogen reduction technologies are in the range of $0.03 to $0.20 per carcass for hogs, and that optimal combinations of technologies may cost as much as $0.47 per carcass. The cost estimates for specific interventions show that power, water, and labor are important to achieve greater pathogen reductions. Thus...
