The Structure of US Food Demand

An exactly aggregable system of Gorman Engel curves for U.S. food consumption is developed and implemented. Box-Cox transformations on prices and income nest functional form. The model nests rank up to rank three. The model is estimated by nonlinear three-stage least squares with annual time series data on 21 foods, 17 nutrients, age and race demographics, and the distribution of income for 1919-1941 and 1947-2000. Results are consistent with full rank three. Point estimates for the Box-Cox parameters on income and prices are 0.86 and 1.09, respectively, strongly rejecting zero and one in both cases. No statistical evidence of serial correlation, specification errors, or parameter instability is found.Aggregation, food demand, functional form, parameter stability, rank, specification errors

Misunderstanding of Front-Of-Package Nutrition Information on US Food Products.

Front-of-package nutrition symbols (FOPs) are presumably readily noticeable and require minimal prior nutrition knowledge to use. Although there is evidence to support this notion, few studies have focused on Facts Up Front type symbols which are used in the US. Participants with varying levels of prior knowledge were asked to view two products and decide which was more healthful. FOPs on packages were manipulated so that one product was more healthful, allowing us to assess accuracy. Attention to nutrition information was assessed via eye tracking to determine what if any FOP information was used to make their decisions. Results showed that accuracy was below chance on half of the comparisons despite consulting FOPs. Negative correlations between attention to calories, fat, and sodium and accuracy indicated that consumers over-relied on these nutrients. Although relatively little attention was allocated to fiber and sugar, associations between attention and accuracy were positive. Attention to vitamin D showed no association to accuracy, indicating confusion surrounding what constitutes a meaningful change across products. Greater nutrition knowledge was associated with greater accuracy, even when less attention was paid. Individuals, particularly those with less knowledge, are misled by calorie, sodium, and fat information on FOPs

Struggle for Leadership: the Competitiveness of the EU and US Food Industry

Globalization is an important issue in the food industry, although most food is still locally produced and consumed. Many small and medium enterprises characterize the industry. Results of WTO negotiations intensify the international competition, in which the EU and USA are the largest players. Countries like Brazil, India and China are gaining market share. This raises the following research questions: 1. How competitive are the EU and US food industry and their sub-sectors? 2. Which role plays innovation and legislation in the competitiveness of the industry? 3. How will the competitiveness develop under future globalization and trade liberalization? The goal of this study is to fill these knowledge gaps.Agribusiness, International Relations/Trade,

Ustekinumab for the treatment of psoriatic arthritis: an update.

Psoriatic arthritis occurs in 30% of psoriasis patients, and the treatment can be challenging in some patients. Recently, the US Food and Drug Administration approved ustekinumab, a fully human monoclonal antibody, for the management of psoriatic arthritis. In this article, we review large-scale randomized clinical trials addressing the efficacy and safety profile of ustekinumab for the treatment of psoriatic arthritis

Does Market Concentration Promote or Reduce New Product Introductions? Evidence from US Food Industry

This study analyzes the relationship between market concentration and new product introductions using an extensive annual panel data set covering the period 1983 to 2004 from the US processed food industry. We test the new theory, which argues that new product introductions are influenced by the anticipation of future mergers. The evidence suggests that market concentration increases new product introductions and product introductions spur subsequent mergers in the US processed food industry. Hence it provides evidence in support of the anticipatory mergers theory.Food Consumption/Nutrition/Food Safety, Marketing,

FORECASTING FUTURE EMPLOYMENT OPPORTUNITIES FOR FOOD, AGRICULTURE, AND NATURAL RESOURCES HIGHER EDUCATION GRADUATES USING ADJUSTED BUREAU OF LABOR FORECASTS

Forecasts of the number of future professionals required for an ongoing safe, efficient US food system are highly important. The demand for adequately prepared higher education graduates must be met by the US Food, Agriculture, and Natural Resources Education System. Without accurate forecasts of the human resource needs of the food sector of the economy, adequate professionals may not be available when needed. This research effort makes use of Bureau of Labor Statistics (BLS) forecasted employment opportunities. The estimation of professionals required in the food and agriculture sectors of the economy is developed by selecting and manipulating data from the BLS model that is relevant to food and agriculture careers. These forecasts of needed professionals can be used by Directors of Resident Instruction to manage the educational system to meet the food sector demands for adequately educated human resources.employment, employment opportunities, food, agriculture, natural resources, directed graphs, education, bureau of labor, Labor and Human Capital,

MARKET POWER AND OFF-INVOICE TRADE PROMOTIONS IN THE US: AN EMPIRICAL INVESTIGATION

This article employs a Tobit model to examine whether the market power of manufacturers and retailers influence trade promotion decisions in the US food sector. Greater retailer market power increases allocation of funds to off-invoice trade promotions. We find evidence that the balance of power favors food retailers.Marketing,

Rapid determination of anti-tuberculosis drug resistance from whole-genome sequences

Mycobacterium tuberculosis drug resistance (DR) challenges effective tuberculosis disease control. Current molecular tests examine limited numbers of mutations, and although whole genome sequencing approaches could fully characterise DR, data complexity has restricted their clinical application. A library (1,325 mutations) predictive of DR for 15 anti-tuberculosis drugs was compiled and validated for 11 of them using genomic-phenotypic data from 792 strains. A rapid online ‘TB-Profiler’ tool was developed to report DR and strain-type profiles directly from raw sequences. Using our DR mutation library, in silico diagnostic accuracy was superior to some commercial diagnostics and alternative databases. The library will facilitate sequence-based drug-susceptibility testing
