An Experimental Design to Test the Main and Interaction Effects of CSR Involvement, Brand Naming, and Pricing on Purchase Intentions in Thailand

摘要

This study attempted to test the main and interaction effects of CSR involvement, brand naming, and pricing on consumers’ purchase intentions by using a 2 x 2 x 2 experimental design. CSR involvement was based on a cause-related marketing campaign. Brand naming was based on a local/Thai brand name and a foreign brand name signifying that the product is from a renowned country. High prices and low prices were adopted for the pricing factor. A computer notebook was used to represent a high involvement and technological product for the experiment. Siam Computer was used to represent a Thai brand name whereas Toshisu was used to represent a foreign brand name. Students from a local university were recruited as experimental subjects. Fifty subjects were randomly assigned to each of the eight experimental conditions. All three experimental factors were found to have significant effects on purchase intentions. The levels of purchase intentions were found to be higher for products with CSR involvement, foreign brand name, and lower prices. The two way interaction effects suggested that CSR involvement had a positive effect on products with foreign brand name and higher prices. The effect of pricing was found to be stronger for products using Thai brand name. The three way interaction effect suggested that for a high price condition, CSR involvement had a strong effect on purchase intentions for products using a foreign brand name whereas in a low price condition, CSR involvement had no significant effect regardless of the name of the brand.
