Question 14.55

14.55 Shopping and bargaining in Mexico.

Price haggling and other bargaining behaviors among consumers have been observed for a long time. However, research addressing these behaviors, especially in a real-life setting, remains relatively sparse. A group of researchers recently performed a small study to determine whether gender or nationality of the bargainer has an effect on the final price obtained.11 The study took place in Mexico because of the prevalence of price haggling in informal markets. Salespersons working at various informal shops were approached by one of three bargainers looking for a specific product. After an initial price was stated by the vendor, bargaining took place. The response was the difference between the initial and the final price of the product. The bargainers were a Spanish-speaking Hispanic male, a Spanish-speaking Hispanic female, and an Anglo non-Spanish-speaking male. The following table summarizes the results.

Bargainer
Hispanic male 40 1.055
Hispanic female 40 2.310
Anglo male 40 1.050
  1. To compare the mean reductions in price, what are the degrees of freedom for the ANOVA statistic?
  2. The reported test statistic is . Give an approximate (from a table) or exact (from software) -value. What do you conclude?
  3. To what extent do you think the results of this study can be generalized? Give reasons for your answer.

(a) . (b) . There are significant average reduction differences among the different groups of bargainers. (c) Because the bargainer was the same person each time, there is no way to differentiate if the average reduction was due to race/gender or due to individual ability to bargain. Hence, the results would certainly not be generalizable.
