Low Starting Prices Lead to High Auction Sales.
Why does this happen? For starters, as the researchers explained in the June 2006 issue of The Journal of Personality and Social Psychology, low starting prices reduce barriers to entry, tempting even idle browsers to place bids. The increased traffic then generates higher final prices as more buyers bid against one another. Psychological forces play into it as well. Low starting prices entice bidders to invest time and energy in the auction, and while every M.B.A. student knows it’s dumb to base decisions on sunk costs, the eBay bidders did just that, escalating their commitments to their previous bids.
