Siam Computer was used to represent a Thai brand name whereas Toshisu was used to represent aforeign brand name. Students from a local university were recruited as experimental subjects. Fifty subjects wererandomly assigned to each of the eight experimental conditions. All three experimental factors were found tohave significant effects on purchase intentions. The levels of purchase intentions were found to be higher forproducts with CSR involvement, foreign brand name, and lower prices. The two way interaction effectssuggested 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.
