We report laboratory experiments that use new, visually oriented software to explore the dynamics of 3x3 games with intransitive best responses. Each moment, each player is matched against the entire population, here 8 human subjects. A "heat map" offers instantaneous feedback on current profit...

Human subjects decide when to sink a fixed cost "C" to seize an irreversible investment opportunity whose value "V" is governed by Brownian motion. The optimal policy is to invest when "V" first crosses a threshold "V"* = (1 + "w"*)"C", where the wait option premium "w"* depends on drift,...

Human subjects decide when to sink a fixed cost C to seize an irreversible investment opportunity whose value V is governed by Brownian motion. The optimal policy is to invest when V first crosses a threshold V* = (1 + w*)C, where the wait option premium w* depends on drift, volatility, and...

We develop a framework for modelling choice in the presence of framing effects. An extended choice function assigns a chosen element to every pair (A, f) where A is a set of alternatives, and f is a frame. A frame includes observable information that is irrelevant in the rational assessment of...

An individual displays various preference orderings in different payoff-irrelevant circumstances. It is assumed that the variation in the observed preference orderings is the outcome of some cognitive process that distorts the underlying preferences of the individual. We introduce a framework...

For a market with a finite number of agents, pairwise matching, and bargaining, it is shown that, even when the market is frictionless, the equilibrium is not necessarily competitive. It depends on the amount of information agents use. If their behavior is conditioned only on the sets of agents...
