Renewing the International Monetary Fund: A Review of the Issues

Given the rapid and ongoing integration of the global economy, the International Monetary Fund needs to renew its role, governance structure, and functions if it is to maintain its relevance as the institution charged with promoting global financial stability. Lecavalier and Santor examine the areas of possible reform, including quota, voice, and representation; internal governance; surveillance; lending instruments; finances; and the Fund's role in low-income countries. They also review current Bank of Canada research that supports these reform efforts, including an integrated framework for IMF surveillance recently developed at the Bank.

Systemic Risk and Collateral Adequacy

Staff working paper 2019-23 Radoslav Raykov
Many derivatives markets use collateral requirements calculated with industry-standard but dated methods that are not designed with systemic risk in mind. This paper explores whether the conservative nature of conventional collateral requirements outweighs their lack of consideration of systemic risk.

Market Concentration and Uniform Pricing: Evidence from Bank Mergers

Staff working paper 2021-9 João Granja, Nuno Paixão
We show that US banks price deposits almost uniformly across their branches and that this pricing practice is more important than increases in local market concentration in explaining the deposit rate dynamics following bank mergers.

Time-Consistent Management of a Liquidity Trap with Government Debt

Staff working paper 2018-38 Dmitry Matveev
This paper studies optimal discretionary monetary and fiscal policy when the lower bound on nominal interest rates is occasionally binding in a model with nominal rigidities and long-term government debt. At the lower bound it is optimal for the government to temporarily reduce debt.

The MacroFinancial Risk Assessment Framework (MFRAF), Version 2.0

Technical report No. 111 Jose Fique
This report provides a detailed technical description of the updated MacroFinancial Risk Assessment Framework (MFRAF), which replaces the version described in Gauthier, Souissi and Liu (2014) as the Bank of Canada’s stress-testing model for banks with a focus on domestic systemically important banks (D-SIBs).

Measuring Limits of Arbitrage in Fixed-Income Markets

Staff working paper 2017-44 Jean-Sébastien Fontaine, Guillaume Nolin
We use relative value to measure limits to arbitrage in fixed-income markets. Relative value captures apparent deviations from no-arbitrage relationships. It is simple, intuitive and can be computed model-free for any bond.

Analysis of Asymmetric GARCH Volatility Models with Applications to Margin Measurement

Staff working paper 2018-21 Elena Goldman, Xiangjin Shen
We explore properties of asymmetric generalized autoregressive conditional heteroscedasticity (GARCH) models in the threshold GARCH (GTARCH) family and propose a more general Spline-GTARCH model, which captures high-frequency return volatility, low-frequency macroeconomic volatility as well as an asymmetric response to past negative news in both autoregressive conditional heteroscedasticity (ARCH) and GARCH terms.

Estimating Systematic Risk Under Extremely Adverse Market Conditions

Staff working paper 2016-22 Maarten van Oordt, Chen Zhou
This paper considers the problem of estimating a linear model between two heavy-tailed variables if the explanatory variable has an extremely low (or high) value. We propose an estimator for the model coefficient by exploiting the tail dependence between the two variables and prove its asymptotic properties.
