Impulse Purchasing

  1. 1. What is an “Impulse Purchase”?<br />“Researchers agree that impulse buying occurs when an individual makes an unintended, unreflective, and immediate purchase.” <br />(Jones et al. 2003, Journal of Business Research)<br />Jones et al.’s Citation for this claim?<br /><ul><li> Rook 1987
  2. 2. Rook and Fisher 1995</li></ul>“There has been little consensus on what impulse purchasing actually is.” <br />(Rook 1987)<br />John Dinsmore, dinsmojb@mail.uc.edu, Slide 1<br />
  3. 3. “Impulse Purchase”: Dissonance<br /><ul><li> “unplanned purchasing”. . . “occurring most frequently at the grocery store” (Kollat & Willet 1967)
  4. 4. “Remembering that one needs a gallon of milk or some toilet paper does not commonly involve truly impulsive behavior.” (Stern 1962)
  5. 5. “Unintended and unplanned. . . not sufficient basis for categorizing a purchase as impulse” (Rook 1987)
  6. 6. “impulsiveness” was not associated with impulse purchasing (Kollat & Willet 1967)
  7. 7. Choices made without considering long term interests (Stigler and Becker 1977)
  8. 8. Quick response to stimulus without deliberation and evaluation of consequences (Buss & Plomin 1975)</li></ul>John Dinsmore, dinsmojb@mail.uc.edu, Slide 2<br />
  9. 9. “Impulse Purchase”: Dissonance<br />“Impulse buying is a sudden and immediate purchase with no pre-shopping intentions either to buy the specific product category or to fulfill a specific buying task. The behavior occurs after experiencing an urge to buy and it tends to be spontaneous and without a lot of reflection (i.e., it is “impulsive”). It does not include the purchase of a simple reminder item, which is an item that is simply out of stock at home.” (Beatty, Ferrell 1998)<br />John Dinsmore, dinsmojb@mail.uc.edu, Slide 3<br />
  10. 10. “Impulse Purchase”: Dissonance<br />“a sudden spontaneous inclination or incitement to <br />some usually unpremeditated action”<br />—Merriam-Webster’s Medical Dictionary<br />an unpremeditated <br />Purchase<br />“Impulse buying occurs when a consumer experiences a sudden, often powerful and persistent urge to buy something immediately.”(Rook 1987)<br />John Dinsmore, dinsmojb@mail.uc.edu, Slide 4<br />

  21. 21. Why We Care @ Impulse Purchasing<br /><ul><li> Lipstick Effect</li></ul>“After the terrorist attacks of 2001 deflated the economy, Mr. Lauder noticed that his company was selling more lipstick than usual. He hypothesized that lipstick purchases are a way to gauge the economy. When it’s shaky, he said, sales increase as women boost their mood with inexpensive lipstick purchases instead of $500 slingbacks.”<br />“April Lane Benson, a psychologist in Manhattan who works with compulsive spenders, said there are two reasons why women would want lip color more than other affordable pleasures. . .’The mouth is an organ of so much pleasure.’ . . . ‘When women use lipstick in times of stress,” Dr. Benson said, “they’re doing it to put forward an image that they are more alive and more vibrant, and not as down in the mouth. It’s part of the uniform of desirability and attractiveness. A shirt or a cup of gelato is much farther removed from that.”<br />“Hard Times But Your Lips Look Great”, The New York Times, May 1, 2008<br />John Dinsmore, dinsmojb@mail.uc.edu, Slide 7<br />
