Think of R&D, competition, and the cost of advertising – all these factors reflect the ease of selling on a marketplace. Another way to call it is the barriers to entry. The lower are the barriers to entry, the more the seller is willing to compromise on price.
Stock availability is an important factor in deciding on price. The lower is the stock level, the lower is the price elasticity for the seller. After all, it’s better to have slow-moving goods selling at a higher price, rather than having all stock sold out at low price at once.
The breakeven point is a deal breaker. The closer the selling price gets to the breakeven point, the lower is the acceptable margin level, and the lower is the price elasticity for the seller.
