Detecting exuberance in house prices across Canadian cities

Staff Analytical Note 2021-9 Ugochi Emenogu, Cars Hommes, Mikael Khan
We introduce a model to detect periods of extrapolative house price expectations across Canadian cities. The House Price Exuberance Indicator can be updated on a quarterly basis to support the Bank of Canada’s broader assessment of housing market imbalances.

What People Believe About Monetary Finance and What We Can(’t) Do About It: Evidence from a Large-Scale, Multi-Country Survey Experiment

Staff Working Paper 2023-36 Cars Hommes, Julien Pinter, Isabelle Salle
We conduct a large-scale survey to shed light on what people believe about public finance. An experiment demonstrates that central bank communication can persistently shift views on monetary financing. It further suggests that views on monetary financing impact support for fiscal discipline.

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.

CANVAS: A Canadian Behavioral Agent-Based Model

The Bank of Canada’s current suite of models faces challenges in addressing network effects that integrate household and firm-level heterogeneity and their behaviours. We develop CANVAS, a Canadian behavioural agent-based model to contribute to the Bank’s next-generation modelling effort. CANVAS improves forecasting performance and expands capacity for model-based scenario analysis.

Behavioral Learning Equilibria in New Keynesian Models

Staff Working Paper 2022-42 Cars Hommes, Kostas Mavromatis, Tolga Özden, Mei Zhu
We introduce behavioral learning equilibria (BLE) into DSGE models with boundedly rational agents using simple but optimal first order autoregressive forecasting rules. The Smets-Wouters DSGE model with BLE is estimated and fits well with inflation survey expectations. As a policy application, we show that learning requires a lower degree of interest rate smoothing.

The COVID-19 Consumption Game-Changer: Evidence from a Large-Scale Multi-Country Survey

A multi-country consumer survey investigates why and how much households decreased their consumption in five key sectors after pandemic-related restrictions were lifted in Europe in July 2020. Beyond infection risk and precautionary saving motives, households also reported not missing some consumption items, which may indicate preference shifts and structural changes in the post-COVID-19 economy.

Ten Isn’t Large! Group Size and Coordination in a Large-Scale Experiment

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.

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.

Inflation Targeting and Liquidity Traps Under Endogenous Credibility

Staff Working Paper 2019-9 Cars Hommes, Joep Lustenhouwer
Policy implications are derived for an inflation-targeting central bank, whose credibility is endogenous and depends on its past ability to achieve its targets. This is done in a New Keynesian framework with heterogeneous and boundedly rational expectations.
