"Power-Distance Belief and Impulsive Buying," authored by Rice University Management Professor Vikas Mittal found Americans who believe in equality are more-impulsive shoppers.
Power-distance belief (PDB) is the degree of power disparity the people of a culture expect and accept. The higher the PDB, measured on a scale of 0 to 100, the more a person accepts disparity and expects power inequality. In general, Americans have a low PDB score relative to people in countries like China and India. The study found that people who have a high PDB score tend to exhibit more self-control and are less impulsive when shopping.
"In our studies, people with low PDB scores spent one-and-a-half times the amount spent by high-PDB individuals when buying daily items like snacks and drinks," Mittal said.
The effect was even more pronounced for "vice goods" -- tempting products like chocolate and candy -- than for "virtue goods" like yogurt and granola bars. The researchers hypothesized that people with low PDB scores -- who also should have lower self-control -- would show even stronger impulsive buying for vice goods because of their desire for immediate gratification. Researchers found low-PDB people spent twice as much on vice goods as high PDB people spent.
For the study, the researchers conducted multiple experiments and surveys. In one large-scale survey, they asked 901 Americans to provide measures of their PDB, or their attitude toward equality. Then, the researchers observed the participants' online shopping behavior by giving them $10 to purchase a selection of items and telling them they could keep any unspent money.
The U.S. scores at a relatively low 40 PDB, compared to Russia (93), the Philippines (94), Singapore (74), China (80) and India (77). Austria (11), Germany (35) and New Zealand (22) also score low, whereas Japan (54), Vietnam (45) and South Africa (49) score more in the middle.
Retailers dealing with multicultural markets may want to apply knowledge about consumers’ cultural background of PDB to adapt their advertising, promotions and displays. “Marketers need to ascertain whether their products or brands are viewed by different consumer segments as virtue or vice products," Mittal said. "Our study shows that vice products will be more susceptible to impulsive buying among low-PDB consumers.”
This is an interesting concept, though I'm not sure how much the average c-store operator can take away from this in terms of product selection, merchandising and marketing. Still, knowing more about your customers is always a good thing. -- Barb Grondin Francella
