2019 Cash Alternative Survey Results
The role of cash in Canadians’ lives has been evolving, as innovations in digital payments have become more widely adopted over the past decade. We contribute to the Bank of Canada’s research on central bank digital currency by monitoring Canadians’ use of cash and their adoption of digital payment methods. -
Survival Analysis of Bank Note Circulation: Fitness, Network Structure and Machine Learning
Using the Bank of Canada's Currency Information Management Strategy, we analyze the network structure traced by a bank note’s travel in circulation and find that the denomination of the bank note is important in our potential understanding of the demand and use of cash. -
Sample Calibration of the Online CFM Survey
The Canadian Financial Monitor (CFM) survey uses non-probability sampling for data collection, so selection bias is likely. We outline methods for obtaining survey weights and discuss the conditions necessary for these weights to eliminate selection bias. We obtain calibration weights for the 2018 and 2019 online CFM samples. -
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. -
Maturity Composition and the Demand for Government Debt
The main objectives of debt management are to raise stable and low-cost funding to meet the government’s financial needs and to maintain a well-functioning market for government securities. -
Cash and COVID-19: The impact of the pandemic on demand for and use of cash
Consumer spending declined significantly during the recent COVID-19 pandemic. This negative shock likely reduced spending across all methods of payment (cash, debit, credit, etc.). The mix of payment methods consumers use could also be affected. We study how the pandemic has influenced the demand for and use of cash. We also offer insights into the use of other payment methods, such as debit and credit cards. -
CBDC adoption and usage: some insights from field and laboratory experiments
This note discusses insights from historical launches of new payment methods and related laboratory experiments on the potential adoption and use of a central bank digital currency in the Canadian context. -
Classical Decomposition of Markowitz Portfolio Selection
In this study, we enhance Markowitz portfolio selection with graph theory for the analysis of two portfolios composed of either EU or US assets. Using a threshold-based decomposition of their respective covariance matrices, we perturb the level of risk in each portfolio and build the corresponding sets of graphs. -
The Market for Acquiring Card Payments from Small and Medium-Sized Canadian Merchants
This note uses industry data and a unique dataset of small and medium-sized merchants to provide insights into the acquirer-merchant market in Canada.
