DEMAND FOR PLANTS SOLD IN NORTH CAROLINA GARDEN CENTERS

Abstract

Demand for selected nursery plants sold in North Carolina (i.e., begonia, dianthus, geranium, impatiens, marigold, petunia, and vinca) was found to be affected more by prices than by income, demographic, and other variables. By using cross-sectional data, a modified AIDS model, incorporating demographic variables and quadratic income response, was estimated. Inverse Mills's ratios were also included in the model to correct for selectivity bias, resulting from zero purchases. Significant own-price elasticities ranged from -0.71 to -1.65, and income elasticities ranged from -0.78 to 0.41.Demand and Price Analysis,
