Experiments in psychology, where subjects estimate confidence intervals to a series of factual questions, have shown that individuals report far too narrow intervals. This has been interpreted as evidence of overconfidence in the preciseness of knowledge, a potentially serious violation of the...

Variability and avrage profits : does Oi's result generalize?
Friberg, Richard (contributor); Martensen, Kaj (contributor) - 2000 - [Elektronische Ressource]
Average profits of a price taker are increasing in the variability of the output price (Oi, 1961). We show that, for the same reason, average profits of the price taker are increasing in the variability of the price of inputs. We proceed to establish that the same holds for a firm with a...

Do opponents' experience matter? : experimental evidence from a quantity precommitment game
Le Coq, Chloé; Jon Thor Sturluson - 2004 - [Elektronische Ressource], Rev. November 10, 2011
This paper investigates why subjects in laboratory experiments on quantity precommitment games consistently choose capacities above the Cournot level - the subgame-perfect equilibrium. We argue that this puzzling regularity may be attributed to players' perceptions of their opponents' skill or...
