Individuals’ tendency to stick to the current state of affairs, known as the status quo bias, has been widely documented over the past 30 years. Yet, the determinants of this phenomenon remain elusive.

We analyze selection of an auction format by an informed seller. We model a game with two stages: first, an informed seller announces a good for sale and chooses an auction format from a set of standard auctions; second, privately informed bidders compete for the object. The game has an important signaling element as the auction choice may signal the seller’s type. We study both private and com...
