• Finding a Needle in a Haystack: A Machine Learning Framework for Anomaly Detection in Payment Systems

  Staff Working Paper 2024-15 Ajit Desai, Anneke Kosse, Jacob Sharples

  Our layered machine learning framework can enhance real-time transaction monitoring in high-value payment systems, which are a central piece of a country’s financial infrastructure. When tested on data from Canadian payment systems, it demonstrated potential for accurately identifying anomalous transactions. This framework could help improve cyber and operational resilience of payment systems.

• Endogenous Credibility and Wage-Price Spirals

  Staff Working Paper 2024-14 Olena Kostyshyna, Tolga Özden, Yang Zhang

  We quantitively assess the risks of a wage-price spiral occurring in Canada over history. We find the risk of a wage-price spiral increases when the inflation expectations become unanchored and the credibility of central banks declines.

• Parallel Tempering for DSGE Estimation

  Staff Working Paper 2024-13 Joshua Brault

  I develop a population-based Markov chain Monte Carlo algorithm known as parallel tempering to estimate dynamic stochastic general equilibrium models. Parallel tempering approximates the posterior distribution of interest using a family of Markov chains with tempered posteriors.

• U.S. Macroeconomic News and Low-Frequency Changes in Small Open Economies’ Bond Yields

  Staff Working Paper 2024-12 Bingxin Ann Xing, Bruno Feunou, Morvan Nongni-Donfack, Rodrigo Sekkel

  Using two complementary approaches, we investigate the importance of U.S. macroeconomic news in driving low-frequency fluctuations in the term structure of interest rates in Canada, Sweden and the United Kingdom. We find that U.S. macroeconomic news is particularly important to explain changes in the expectation components of the nominal, real and break-even inflation rates of small open economies.

• Unintended Consequences of the Home Affordable Refinance Program

  Staff Working Paper 2024-11 Phoebe Tian, Chen Zheng

  We investigate the unintended consequences of the Home Affordable Refinance Program (HARP). Originally designed to help borrowers refinance after the 2008–09 global financial crisis, HARP inadvertently strengthened the market power of incumbent lenders by creating a cost advantage for them. Despite a 2013 policy rectifying this cost advantage, we still find significant welfare losses for borrowers.

• Forecasting Recessions in Canada: An Autoregressive Probit Model Approach

  Staff Working Paper 2024-10 Antoine Poulin-Moore, Kerem Tuzcuoglu

  We forecast recessions in Canada using an autoregressive (AR) probit model. The results highlight the short-term predictive power of the US economic activity and suggest that financial indicators are reliable predictors of Canadian recessions. In addition, the suggested model meaningfully improves the ability to forecast Canadian recessions, relative to a variety of probit models proposed in the Canadian literature.

• CBDC: Banking and Anonymity

  Staff Working Paper 2024-9 Yuteng Cheng, Ryuichiro Izumi

  We examine the optimal amount of user anonymity in a central bank digital currency in the context of bank lending. 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.

• Monetary Policy Transmission Through Shadow and Traditional Banks

  Staff Working Paper 2024-8 Amina Enkhbold

  I investigate how monetary policy transmits to mortgage rates via the mortgage market concentration channel for both traditional and shadow banks in the United States from 2009 to 2019. On average, shadow and traditional banks exhibit only a slight disparity in transmitting monetary shocks to mortgage rates.

• Regulation, Emissions and Productivity: Evidence from China’s Eleventh Five-Year Plan

  Staff Working Paper 2024-7 Brantly Callaway, Tong Li, Joel Rodrigue, Yuya Sasaki, Yong Tan

  We study the degree to which China’s 11th Five-Year Plan softens trade-offs between emissions and output. Our model suggests efficient regulation could have further increased aggregate productivity by 3.5% and output by 4.7% without any increase in aggregate emissions.

• Decomposing Large Banks’ Systemic Trading Losses

  Staff Working Paper 2024-6 Radoslav Raykov

  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.
