How do you know if you’re in a buyer’s market, or a seller’s?

Offline it’s pretty easy to know. There’s price pressure, abundance and not too many people vying for the same house, commodity or mint condition Pee-Wee Herman doll at the yard sale. In the land of the real, markets aren’t terribly efficient. Before the Internet changed everything, retailers were bound by geography and the ability (and willingness) of people to range. That’s why gas costs a lot more right off the highway exit than it does less than a mile down, where strangers would rather not venture. (Now, of course, there’s an app for that.)
