Abstract
Consistent evidence across important domains shows that people's decisions can depend on the order or emphasis with which the attributes of the available options are presented to them. We introduce the first model of such framing effects, which we characterize in terms of observable behavior. We apply the model to study how strategic use of attribute framing affects competition in markets and outcomes of negotiations. We extend the model to stochastic-choice frameworks, which are often used in practice. We explain how it can be embedded into the standard rational-inattention framework to link our attribute framing with previously studied list-order effects.
