Learning in a Complex World: Insights from an OLG Lab Experiment Staff Working Paper 2023-13 Cars Hommes, Stefanie J. Huber, Daria Minina, Isabelle Salle This paper brings novel insights into group coordination and price dynamics in complex environments. We implement a chaotic overlapping-generation model in the lab and find that group coordination is always on the steady state or on the two-cycle and that behavior is non-monotonic.

Inflation, Output, and Welfare in the Laboratory Staff Working Paper 2023-11 Janet Hua Jiang, Daniela Puzzello, Cathy Zhang We investigate the effect of inflation on output and welfare in the laboratory. Consistent with monetary theory, we find that inflation acts as a tax on monetary exchange and reduces output and welfare.

What to Target? Insights from a Lab Experiment Staff Working Paper 2021-53 Isabelle Salle In a laboratory experiment, we ask participants to predict inflation using three different policy regimes: inflation targeting—with and without greater communication of the target—average inflation targeting and price level targeting. We use participants’ predictions to compare the level and stability of inflation under each regime.

How Long is Forever in the Laboratory? Three Implementations of an Infinite-Horizon Monetary Economy Staff Working Paper 2021-16 Janet Hua Jiang, Daniela Puzzello, Cathy Zhang Standard monetary models adopt an infinite horizon with discounting. Testing these models in the lab requires implementing this horizon within a limited time frame. We compare three approaches to such an implementation and discuss their relative advantages.

Ten Isn’t Large! Group Size and Coordination in a Large-Scale Experiment Staff Working Paper 2020-30 Jasmina Arifovic, Cars Hommes, Anita Kopányi-Peuker, Isabelle Salle Economic activities typically involve coordination among a large number of agents. These agents have to anticipate what other agents think before making their own decisions.

Monetary Payoff and Utility Function in Adaptive Learning Models Staff Working Paper 2019-50 Erhao Xie When players repeatedly face an identical or similar game (e.g., coordination game, technology adoption game, or product choice game), they may learn through experience to perform better in the future. This learning behaviour has important economic implications.

Are Long-Horizon Expectations (De-)Stabilizing? Theory and Experiments Staff Working Paper 2019-27 George Evans, Cars Hommes, Isabelle Salle, Bruce McGough Most models in finance assume that agents make trading plans over the infinite future. We consider instead that they are boundedly rational and may only form forecasts over a limited horizon.

Competing Currencies in the Laboratory Staff Working Paper 2017-53 Janet Hua Jiang, Cathy Zhang We investigate competition between two intrinsically worthless currencies as a result of decentralized interactions between human subjects. We design a laboratory experiment based on a simple two-country, two-currency search model to study factors that affect circulation patterns and equilibrium selection.

Adoption of a New Payment Method: Theory and Experimental Evidence Staff Working Paper 2017-28 Jasmina Arifovic, John Duffy, Janet Hua Jiang We model the introduction of a new payment method, e.g., e-money, that competes with an existing payment method, e.g., cash. The new payment method involves relatively lower per-transaction costs for both buyers and sellers, but sellers must pay a fixed fee to accept the new payment method.

Do Sunspots Matter? Evidence from an Experimental Study of Bank Runs Staff Working Paper 2014-12 Jasmina Arifovic, Janet Hua Jiang A "sunspot" is a variable that has no direct impact on the economy’s fundamental condition, such as preferences, endowments or technologies, but may nonetheless affect economic outcomes through the expectations channel as a coordination device. This paper investigates how people react to sunspots in the context of a bank-run game in a controlled laboratory environment.
