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.

How big is cash-futures basis trading in Canada’s government bond market?
Cash-futures basis trading has grown alongside the Government of Canada bond futures market. We examine this growth over time in relation to Government of Canada bond and repurchase agreement markets and provide details on the type of market participants that engage in this type of trading activity. -
Fire Sales and Liquidity Requirements
We study liquidity requirements in a framework with fire sales. The framework nests three common pricing mechanisms and produces the same observables. Absent risk-sharing considerations, the equilibrium is efficient with cash-in-the-market pricing; a liquidity requirement is optimal with second-best-use pricing; and a liquidity ceiling (i.e., a cap on liquid assets) is optimal with adverse selection. -
Liquidity risks at Canadian life insurance companies
We examine how life insurers manage liquidity risks created by their business model. We find that Canadian life insurers did not face significant liquidity draws and continued their usual investment behaviour during the COVID-19 crisis and as interest rates increased in 2022. -
What has been putting upward pressure on CORRA?
From the autumn of 2023 into early 2024, the Canadian Overnight Repo Rate Average (CORRA), a measure of the cost of overnight general collateral Canadian dollar repos, was consistently well above the Bank’s target for the overnight rate. We find that, among several factors, long bond positions that require repo financing are the main driver of the recent upward pressure on CORRA. -
Decomposing Large Banks’ Systemic Trading Losses
Do banks realize simultaneous trading losses because they invest in the same assets, or because different assets are subject to the same macro shocks? This paper decomposes the comovements of bank trading losses into two orthogonal channels: portfolio overlap and common shocks. -
Intermediary Market Power and Capital Constraints
We examine how intermediary capitalization affects asset prices in a framework that allows for intermediary market power. We introduce a model in which capital-constrained intermediaries buy or trade an asset in an imperfectly competitive market, and we show that weaker capital constraints lead to both higher prices and intermediary markups. -
Tattle-tails: Gauging downside risks using option prices
Options markets offer unique insights into the changing risks different assets face, which helps us better understand the broader risks to the Canadian economy. We show how option prices help reveal that investors did not anticipate large downside risks to either major Canadian banks or economic growth during the March 2023 financial sector system stress, a period when policy-makers and investors were unsure of what the future held for Canada’s economy. -
Generalized Autoregressive Gamma Processes
We introduce generalized autoregressive gamma (GARG) processes, a class of autoregressive and moving-average processes in which each conditional moment dynamic is driven by a different and identifiable moving average of the variable of interest. We show that using GARG processes reduces pricing errors by substantially more than using existing autoregressive gamma processes does. -
The contribution of firm profits to the recent rise in inflation
We measure the contribution to inflation from the growth in markups of Canadian firms. The dynamics of inflation and markups suggest that changes in markups could account for less than one-tenth of inflation in 2021. Further, they suggest that peak inflation was driven primarily by changes in the costs of firms.
