The Role of Public Money in the Digital Age
A well-functioning monetary system is characterized by public and private forms of money that exchange at par as value flows freely between them. A relevant retail public money—whether in the form of cash, a central bank digital currency or both—is a necessary component of such a monetary system. -
Untapped Potential: Mobile Device Ownership and Mobile Payments in Canada
We present a two-stage model of mobile phone and mobile payment usage that controls for selectivity. This reveals unobserved factors that work against having a mobile phone and toward mobile paying. Therefore, people who are unable to acquire or choose not to own a mobile device might have unmet payment needs. -
Analysis of DeFi Oracles
Oracles are constructs used in decentralized finance to price assets relative to each other. However, oracles contain defects that could lead to manipulation attacks. Such attacks exploit pricing models embedded within oracles to defraud creators and users. We automatically verify defects, which if mitigated, improves the security of digital currency. -
Deriving Longer-Term Inflation Expectations and Inflation Risk Premium Measures for Canada
We present two models for long-term inflation expectations and inflation risk premiums for Canada. -
2023 Methods-of-Payment Survey Report: The Resilience of Cash
We present key results from the 2023 Methods-of-Payment Survey. Results show that measures of cash management and use have remained stable since 2020, and that Canadians increased their adoption of payment alternatives such as mobile apps in 2023. -
Demand for Canadian Banknotes from International Travel: Indirect Evidence from the COVID-19 Pandemic
This study uses the COVID-19 travel restrictions to estimate foreign demand for Canadian banknotes. It reveals that international visitors accounted for about 10% of all $100 CAD notes in circulation pre-pandemic, with each visitor carrying an average of $165 in hundred-dollar bills. -
The Role of Beliefs in Entering and Exiting the Bitcoin Market
We develop a model that links investors’ decisions to enter or exit the Bitcoin market with their beliefs about the survival of Bitcoin. Empirical testing using Canadian data reveals that beliefs strongly influence both entries and exits, and this impact varies with time and ownership status. -
The Macroeconomic Implications of Coholding
Coholder households simultaneously carry high-cost credit card debt and low-yield cash. We study the implications of this behavior for fiscal and monetary policy, finding that coholder households have smaller consumption responses in the short run but larger responses in the long run. -
Finding a Needle in a Haystack: A Machine Learning Framework for Anomaly Detection in Payment Systems
Our layered machine learning framework can enhance real-time transaction monitoring in high-value payment systems, which are a central piece of a country’s financial infrastructure. When tested on data from Canadian payment systems, it demonstrated potential for accurately identifying anomalous transactions. This framework could help improve cyber and operational resilience of payment systems.
