Because uncertainty is endemic in a wide variety of economic circumstances, models of decision making under uncertainty play a key role in every field of economics. The standard model of decisions...

Syngjoo Choi, Shachar Kariv

Social learning describes any situation in which economic agents learn by observing the behavior of others. Social learning in networks applies this idea to situations in which agents observe the...

Substantive and Procedural Rationality in Decisions under Uncertainty (2006)

Choi, Syngjoo, Fisman, Raymond, Gale, Douglass, Kariv, Sachar

We report a laboratory experiment that enables us to study systematically the substantive and procedural rationality of decision making under uncertainty. By using novel graphical representations of...

A Cognitive Hierarchy Model of Learning in Networks.” mimo (2006)

Syngjoo Choi

This paper proposes a method for estimating a hierarchical model of bounded rationality in games of learning in networks. A cognitive hierarchy comprises a set of cognitive types whose behavior...

Networks are natural tools for understanding social and economic phenomena. For example, all markets are characterized by agents connected by complex, multilateral information networks, and the...

Consistency, Heterogeneity, and Granularity of Individual Behavior under Uncertainty

Syngjoo Choi, Raymond Fisman, Douglas Gale, Shachar Kariv

By using graphical representations of budget sets over bundles of state-contingent commodities, we generate a very rich data set well-suited to studying behavior under uncertainty at the level of the...

Consistency and Heterogeneity of Individual Behavior under Uncertainty

Syngjoo Choi, Raymond Fisman, Douglas Gale, Shachar Kariv

By using graphical representations of simple portfolio choice problems, we generate a very rich dataset to study behavior under uncertainty at the level of the individual subject. We test the data...

Sequential equilibrium in monotone games: A theory-based analysis of experimental data

Choi, Syngjoo, Gale, Douglas, Kariv, Shachar

A monotone game is an extensive-form game with complete information, simultaneous moves and an irreversibility structure on strategies. It captures a variety of situations in which players make...
