We study the power of item-pricing as a tool for approximately optimizing social welfare in a combinatorial market. We consider markets with m indivisible items and n buyers. The goal is to set prices to the items so that, when agents purchase their most demanded sets simultaneously, no conflicts arise and the obtained allocation has nearly optimal welfare. For gross substitutes valuations, it ...

Intramammary infections in breeding age and pregnant heifers are much higher than previously thought. Many of these infections can persist for long periods of time, are associated with elevated somatic cell counts, and likely impair mammary development during gestation and affect milk production after calving. Prepartum intramammary antibiotic infusion of heifer mammary glands a few weeks befor...

Steer progeny (n = 80) produced by mating British crossbred females to one of three terminal (Charolais) sires or one of five maternal (Angus or Red Angus-Composite) sires were evaluated from birth to harvest to compare the effects of sire type (terminal vs. maternal) on growth performance, carcass characteristics, and net return per head. Steers sired by terminal bulls were heavier (P < 0.05) ...

This article applies the method of difference panel GMM Arellano-Bond for a dataset of eighty two developing countries (These countries are classified into three economies basing on estimates of gross national income (GNI) per capita for the 2014 year by using the World Bank Atlas method 1 ) during a period from 1996 to 2013 to empirically assess the impact of institutional quality (based on si...

The objectives of this study were to describe the relationships between milk urea concentrations and nutritional management, production, and economic variables in commercial dairy herds. Dairy Herd Improvement (DHI) test-day milk urea data, production data, and information on ration nutrient composition and feeding management programs were collected over a 13-mo period from 53 commercial Ontari...

Farmers’ markets presumably benefit local economies through enhanced retention of local dollars. Unlike other studies, the net impact of farmers’ markets on the West Virginia economy is examined. Producer survey results are used in estimating annual direct sales ($1.725 million). Using an IMPLAN-based input-output model, gross impacts are 119 jobs (69 full-time equivalent jobs) and $2.389 milli...

Worksite cafeterias are compelling venues to improve diet quality through environmental changes. We conducted a pre-post study to evaluate how a cafeteria-initiated grill menu redesign influenced sales, revenue, and nutrient content of foods purchased. Secondly, we evaluated consumer opinions about menu changes to inform practices for worksite environment interventions. Monthly sales data (2012...
