Competitive pressures in the cow-calf sector increased in 1995 because of a decline of 27% in calf prices. Technical, allocative, and scale efficiency measures were used to examine the competitiveness of a sample of Kansas beef cow farms. On average, the farms were 78% technically efficient, 81 % allocatively efficient, and 95% scale efficient. Enterprise profitability was correlated positively with the efficiency measures. Inefficiency was related to herd size and degree of specialization. Producers should focus on using capital, feed, and labor more efficiently rather than increasing their size. Increased concentration of the cow-calf sector will not result in large cost savings given the current technology.

This study evaluates the economic competitiveness of a sample of Kansas farrow-to-finish operations by estimating relative firm efficiency using nonparametric mathematical programming techniques. Measures of technical, allocative, scale, economic, and overall efficiency are then related to farm characteristics to identify sources of efficiency. Results indicate that overall efficient farms produce a high quantity of pork per litter, produce a portion of their own feed grains, generate a large portion of their income from swine and other livestock enterprises, and have a lower debt-to-asset ratio.

The ornamental horticultural industry continues to be one of the most rapidly expanding sectors in agriculture. This study examined a decision model for landscape plant production based on portfolio analysis. A quadratic programming model was developed to generate an optimal crop portfolio for a selected southeastern nursery. Empirical results indicate opportunities exist for modest diversification to offset income variability in landscape plant production and marketing.

A method of paired comparison is adapted for use in estimating economic measures of value. The method elicits multiple binary choices for paired items in a choice set. Probability distributions and economic values are estimated nonparametrically and parametrically. The method is applied in an experimental context with a choice set composed of four private goods and several sums of money. The sample’s median value estimates for the goods are generally not different than the market prices for these goods. People who are in the market for a good value the good higher than those not in the market for the good.

The future use of Conservation Reserve Program (CRP) lands is an important agricultural policy issue. To examine the effects of factors that influence landowners’ post-contract use of CRP lands, a survey of Texas High Plains CRP contract holders was conducted in 1992. This study analyzes the results of the survey using a qualitative choice model. It was found that the presence of a livestock enterprise in the current contract holder’s operation increases the probability of these acres remaining in the established cover. Contract holders who value the commodity base have an increased probability of returning their acres to crop production.

Complete agricultural trade liberalization between the United States and the European Union is examined with respect to the agricultural sector. A static, partial equilibrium model, distinguishing among the European Union, the United States, and a politically passive rest of the world, is used to simulate agricultural free trade. The results of this research reveal how European Union and United States adoption of free trade affects domestic and world prices, production, consumption, self-sufficiency, and welfare.

Farmers are interested in knowing whether applying inputs at variable rates across a field is economically viable. The answer depends on the crop, the input, their prices, the cost of variable rate technology (VRT) versus uniform rate technology (URT), and the spatial and yield response variability within each field. Methods were investigated for determining the range of spatial variability over which the return to VRT covers its additional cost compared with URT in fields with multiple management zones. Models developed in this article, or variants thereof, could be used to help farmers make the VRT adoption decision.

A dual cost function approach is developed as an alternative to time series and simplistic approaches for estimating farmers’ expected operating rates of return on assets. A translog restricted cost function is estimated using data provided by 152 North Carolina damy farmers over the period 1976 through 1986. The predicted costs from the fitted restricted cost function are used to construct estimates of farmers’ expected operating rates of return on assets. The estimates from this structural approach explain more of the variation in observed rates than do time series estimates or sample mean observed rates.

This study presents a testing methodology to analyze potential price asymmetries among the farm, wholesale, and retail levels of the U.S. broiler industry. Lag length, direction of causality, and asymmetric relationships are empirically determined. Results suggest that concentration and power of the integrators in the industry have allowed the wholesale price to become the center, causal price in the market. Asymmetric price transmissions, however, are limited. While downward movements in the wholesale price are passed on more fully to growers than increases in the wholesale price, only consumers in the North Central region of the U.S. share a larger portion of wholesalers’ price increases than price decreases.

A two-stage budgeting LES-LA/AIDS system is used to estimate rural household demand in China with special emphasis on changes in demand for fruit and vegetable commodities across different income groups. The own-price elasticity for food was found to be more elastic than that for clothing, housing, durable goods, and other items. Within the food group, price elasticities range from – 1.042 to –0.019. Grain, with an expenditure elasticity of almost unity, is an important staple food for the average rural household. Vegetables are important nonstaple foods relative to fruits. Lower value vegetables are the most price elastic in the vegetable group. Fruits are more price elastic than vegetables, with grapes being the most price elastic. Different income groups share a common demand function.

We estimate the influence of policy-induced price changes and of technology supply on North Carolina flue-cured tobacco yields. The decline in land rent and effective output price that accompanied a 1965 policy change from acreage allotments to poundage quotas caused a 12 percent decrease in yields. Farmer yields were more responsive to yield-increasing technologies under acreage allotments than under poundage quotas. Annual yield growth was 0.5 percent under poundage quotas and 4.32 percent under acreage allotments. The growth rate decline is attributable to changes in relative prices and to a slowdown in the supply of available technologies.

The agricultural biotechnology industry has evolved from a focus on outstanding science to a more mature phase where firms focus on new-term products and building businesses. Understanding complex relationships and distribution channels and a global perspective are crucial to commercialization. Yet, leading-edge technology and early identification of key traits will be critical to developing superior products that ensure competitiveness in the marketplace. Monsanto is organizing around a life sciences model where seed, crop chemicals, pharmaceuticals, and food ingredient businesses will exploit mutual synergies driven by basic science and discovery.

This study estimates the value of policies that would mandate labeling of beef from cattle produced with growth hormones or fed genetically modified corn. At no cost, 85 percent of respondents desired mandatory labeling of beef produced with growth hormones and 64 percent of respondents preferred mandatory labeling of beef fed genetically modified corn. Estimates suggest that consumers would be willing to pay 17.0 percent and 10.6 percent higher prices for beef on average to obtain information provided via mandatory labeling about whether the beef is from cattle produced with growth hormones or fed genetically modified corn, respectively.

Two methods were used to estimate the cost of forward contracting hard red winter wheat. One hundred days before delivery, the estimated cost of forward contracting ranged from six cents/bu to eight cents/bu. Thus, further evidence is provided that the cost of forward contracting grain is not zero.

Data from 100 farming-dependent counties in the U.S. are used to measure the impact of acreage reduction programs on the level of the rural nonfarm population. Results of a simultaneous equation model suggest that the programs had a negative influence on the number of rural nonfarm people, reducing the rural nonfarm population in these counties by an estimated 15–16% over the 1960–90 period.
