Advances in variance analysis permit the splitting of the total quadratic variation of a jump diffusion process into upside and downside components.

Capital markets and their related financial instruments make an important contribution to the welfare of Canadians. The Bank of Canada is interested in the efficient functioning of capital markets through each of its responsibilities for monetary policy, the financial system, and funds management. Hendry and King highlight the key findings of Bank research published over the past year that addresses capital market efficiency and summarize lessons that have been learned. The research conducted thus far suggests that Canadian capital markets are efficient for a capital market of Canada's size but are less diverse than the U.S. capital markets, indicating that there is room for improvement in certain areas.

This paper documents the properties of Government of Canada securities in cash, repo and securities lending transactions over their life cycle. By tracking every security from issuance to maturity, we are able to highlight inter-linkages between the markets for cash and for specific securities.

Anonymity, defined as the lender’s inability to discern an entrepreneur’s actions that enable fund diversion, influences the choice of payment instrument due to its impact on a bank’s lending decisions.

We explore quantitative and qualitative information about Canadians who face barriers to making digital payments. We also consider the implications of ongoing digitalization for modern financial inclusion and a potential central bank digital currency.
