MODELING FRESH ORGANIC PRODUCE CONSUMPTION: A GENERALIZED DOUBLE-HURDLE MODEL APPROACH

Using actual retail data, this study is intended to profile consumers' social economic characteristics related to the growth of the fresh organic produce market with a generalized double-hurdle model. The nested test shows that the above model performs significantly better than Cragg's independent double-hurdle model and Tobit model.Food Consumption/Nutrition/Food Safety,

Estimation of a Composite Food Demand System for the United States—A Revisit

We revisit the composite food demand system for the United States covering the period from 1953 to 2008. We were unable to produce elasticity measures that are as close or similar to those reported in Huang and Haidacher (1983), although the same demand system specification was employed. Our results based on the more recent data set of 1982-2008 show that most of the own-price elasticities are negative and statistically significant, varying from -.1861 (poultry) to -.9476 (nonfood). In general, the estimated own-price elasticities appear to be smaller in magnitude or more inelastic than previously reported. In contrast, we estimate the significant income elasticities for food vary from .5172 (dairy) to 4.6687 (fish), while Huang and Haidaicher (1983) report their income elasticities to vary from -.6343 (fruits) to .5748 (fats & oils). The estimated income elasticities for nonfood group appear to remain fairly constant among different studies, ranging from 1.0407 to1.2035.Differential-form demand system, iterative seemingly unrelated regression, Engel aggregation, Homogeneity, Symmetry, Uncompensated and compensated elasticities, Demand and Price Analysis, Food Consumption/Nutrition/Food Safety,

Organic Premiums of U.S. Fresh Produce

The study uses the 2005 Nielsen Homescan panel data to estimate price premiums and discounts associated with product attributes, market factors, and consumer characteristics, focusing on the organic attribute for 5 major fresh fruits and 5 major fresh vegetables in the United States. The results suggest that the organic attribute commands a significant price premium, which varies greatly from 13 cents per pound for bananas to 86 cents per pound for strawberries among fresh fruits and from 13 cents per pound for onions to 50 cents per pound for peppers among fresh vegetables. In terms of percentages, the estimated organic price premiums vary from 20% above prices paid for conventional grapes to 42% for strawberries among fresh fruits and from 15% above prices paid for conventional carrots and tomatoes to 60% for potatoes. Furthermore, prices paid for fresh produce are found to vary by other product attributes, market factors, and household characteristics.fresh fruits and vegetables, hedonic price, organic produce, organic premium, product attributes, Nielsen Homescan, Agricultural Finance,

How Much are Consumers Paying for Organic Baby Food?

Using retail purchase data, price premiums and discounts associated with household demographics, market factors, and product attributes (focusing on the organic attribute for strained baby food) are estimated using a hedonic pricing model. Results suggest that the organic premium ranges from about 12 to 49 percent in 2004 and from 30 to 52 percent in 2006. Tests for significant changes relative to product attributes show that while the price of conventional baby food has stayed relatively the same, the premium for organic baby food has increased.organic baby food, hedonic price, market factors, product attributes, Nielsen Homescan, organic premium, Consumer/Household Economics, Demand and Price Analysis,

Does Price or Income Affect Organic Choice? Analysis of U.S. Fresh Produce Users

This study analyzes consumer purchasing behavior of organic fresh fruits and vegetables using the 2006 Nielsen Homescan panel. An ordered logit model was estimated to quantify the impacts of economic and socio-demographic factors on the probability of a household belonging to a specific organic user group—devoted, casual, or nonuser. Results suggest that price and income, to some extent, affect consumer purchases of organic produce. Additionally, the profile of an organic produce user is most likely to consist of an Hispanic household residing in the Western United States with children under 6 years old and a household head older than 54 years with at least a college degree.Nielsen Homescan data, ordered logit, organic fruits and vegetables, user groups, Agribusiness, Consumer/Household Economics, Crop Production/Industries, Demand and Price Analysis, Food Consumption/Nutrition/Food Safety, C25, D12, M31, Q11,

Protection of Artists\u27 Rights under the Korean Copyright Law

The term artists includes film, television ( TV ), stage, and musical actors and actresses ( actors ), pop singers and musicians, dancers, fashion models, and classical musicians. Although the same analysis can be applied to all of the categories above mentioned, this article solely focuses on pop singers and actors.

Management of hypercalcemia of malignancy

Malignancy is one of the most common causes of hypercalcemia, particularly in cancer associated with bone metastases. Hypercalcemia occurs in up to 20% to 30% of cancer patients at some time during the course of their disease. Clinical manifestations of hypercalcemia vary in calcium level in blood. Signs and symptoms of hypercalcemia occur when the serum calcium level rises above those ranges. Fluids are first-line treatment with hypercalcemia followed by bisphosphanates if the calcium is high and the patient is experiencing symptoms. Various other medications are used as second-line agents in hypercalcemia of malignancy
