A Dynamic Factor Model for Commodity Prices
In this note, we present the Commodities Factor Model (CFM), a dynamic factor model for a large cross-section of energy and non-energy commodity prices. The model decomposes price changes in commodities into a common “global” component, a “block” component confined to subgroups of economically related commodities and an idiosyncratic price shock component. -
The MacroFinancial Risk Assessment Framework (MFRAF), Version 2.0
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). -
How to Predict Financial Stress? An Assessment of Markov Switching Models
This paper predicts phases of the financial cycle by using a continuous financial stress measure in a Markov switching framework. The debt service ratio and property market variables signal a transition to a high financial stress regime, while economic sentiment indicators provide signals for a transition to a tranquil state. -
Retrieving Implied Financial Networks from Bank Balance-Sheet and Market Data
In complex and interconnected banking systems, counterparty risk does not depend only on the risk of the immediate counterparty but also on the risk of others in the network of exposures. -
Adoption of a New Payment Method: Theory and Experimental Evidence
We model the introduction of a new payment method, e.g., e-money, that competes with an existing payment method, e.g., cash. The new payment method involves relatively lower per-transaction costs for both buyers and sellers, but sellers must pay a fixed fee to accept the new payment method. -
Detecting Scapegoat Effects in the Relationship Between Exchange Rates and Macroeconomic Fundamentals
This paper presents a new testing method for the scapegoat model of exchange rates that aims to tighten the link between the theory on scapegoats and its empirical implementation. This new testing method consists of a number of steps. -
A Three‐Frequency Dynamic Factor Model for Nowcasting Canadian Provincial GDP Growth
This paper estimates a three‐frequency dynamic factor model for nowcasting Canadian provincial gross domestic product (GDP). Canadian provincial GDP is released by Statistics Canada on an annual basis only, with a significant lag (11 months). -
Should Central Banks Worry About Nonlinearities of their Large-Scale Macroeconomic Models?
How wrong could policymakers be when using linearized solutions to their macroeconomic models instead of nonlinear global solutions? -
Assessing the Predictive Ability of Sovereign Default Risk on Exchange Rate Returns
Increased sovereign credit risk is often associated with sharp currency movements. Therefore, expectations of the probability of a sovereign default event can convey important information regarding future movements of exchange rates.
