Housing Affordability and Parental Income Support
In many countries, the cost of housing has greatly outpaced income growth, leading to a housing affordability crisis. Leveraging Canadian loan-level data and quasi-experimental variation in payment-to-income constraints, we document an increasing reliance of first-time homebuyers on financial help from their parents, through mortgage co-signing. We show that parental support can effectively relax borrowing constraints—potentially to riskier borrowers. -
Central Bank Digital Currency and Transmission of Monetary Policy
How does the transmission of monetary policy change when a central bank digital currency (CBDC) is introduced in the economy? Does CBDC design matter? We study these questions in a general equilibrium model with nominal rigidities, liquidity frictions, and a banking sector where commercial banks face a leverage constraint. -
Credit Card Minimum Payment Restrictions
We study a government policy that restricts repayment choices with the aim of reducing credit card debt and estimate its effects by applying a difference-in-differences methodology to comprehensive credit-reporting data about Canadian consumers. We find the policy has trade-offs: reducing revolving debt comes at a cost of reducing credit access, and potentially increasing delinquency. -
The reliance of Canadians on credit card debt as a predictor of financial stress
I analyze the relationship between carrying a credit card balance and future financial stress. I find that carrying a balance significantly increases the likelihood that credit card holders miss future debt payments. This likelihood tends to rise as credit card balances grow and are held for long periods. -
Could all-to-all trading improve liquidity in the Government of Canada bond market?
We find that on any given day, nearly half of Government of Canada bond transactions by clients of dealers can be offset with other clients, including during the turmoil in March 2020. Our results show that under certain conditions clients could potentially trade directly with each other and are a step towards understanding the relevance of broader all-to-all trading in the Government of Canada bond market. -
The Ecology of Automated Market Makers
This paper describes the ecology of automated market makers, which are the most popular decentralized exchange model for the pricing and trading of crypto assets within decentralized finance. -
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.
