I would never advocate a woman responding to a review, negative or positive about her in coed. Like Sixx said, business's don't do it because its normally futile and doesn't look good.
Perfect Competition. It's an economic term. It requires a list of 8 qualifications making a market competitive, one of those being perfect information. It's considered the ideal, with perfect pricing, availability, and all the other good things economists look for. There are obviously some characteristics that the escorting market will never be able to obtain, but theoretically the closer we get the more fair the market structure will be. In a truly competitive (in the economic sense) market, women would price at the marginal cost.
However, I don't believe we offer a commodity, so that will never happen.
