• Simulating Intraday Transactions in the Canadian Retail Batch System

  Staff Working Paper 2023-1 Nellie Zhang

  This paper proposes a unique approach to simulate intraday transactions in the Canadian retail payments batch system when such transactions are unobtainable. The simulation procedure has potential for helping with data-deficient problems where only high-level aggregate information is available.

• Improving the Efficiency of Payments Systems Using Quantum Computing

  Staff Working Paper 2022-53 Christopher McMahon, Donald McGillivray, Ajit Desai, Francisco Rivadeneyra, Jean-Paul Lam, Thomas Lo, Danica Marsden, Vladimir Skavysh

  We develop an algorithm and run it on a hybrid quantum annealing solver to find an ordering of payments that reduces the amount of system liquidity necessary without substantially increasing payment delays.

• Comparison of Bayesian and Sample Theory Parametric and Semiparametric Binary Response Models

  Staff Working Paper 2022-31 Xiangjin Shen, Iskander Karibzhanov, Hiroki Tsurumi, Shiliang Li

  We use graphic processing unit computing to compare Bayesian and sample theory semiparametric binary response models. Our findings show that optimal bandwidth does not outperform regular bandwidth in binary semiparametric models.

• Quantum Monte Carlo for Economics: Stress Testing and Macroeconomic Deep Learning

  Staff Working Paper 2022-29 Vladimir Skavysh, Sofia Priazhkina, Diego Guala, Thomas Bromley

  Using the quantum Monte Carlo algorithm, we study whether quantum computing can improve the run time of economic applications and challenges in doing so. We apply the algorithm to two models: a stress testing bank model and a DSGE model solved with deep learning. We also present innovations in the algorithm and benchmark it to classical Monte Carlo.

• Transition Scenarios for Analyzing Climate-Related Financial Risk

  Staff Discussion Paper 2022-1 Y.-H. Henry Chen, Erik Ens, Olivier Gervais, Hossein Hosseini, Craig Johnston, Serdar Kabaca, Miguel Molico, Sergey Paltsev, Alex Proulx, Argyn Toktamyssov

  Climate transition scenarios clarify climate-related risks to our economy and financial system. This paper summarizes key results of Canada-relevant scenarios developed in a pilot project on climate risk by the Bank of Canada and the Office of the Superintendent of Financial Institutions.

• Stressed but not Helpless: Strategic Behaviour of Banks Under Adverse Market Conditions

  Staff Working Paper 2021-35 Grzegorz Halaj, Sofia Priazhkina

  Our stress-testing tool considers banks under stress that can strategically manage their balance sheets. Using confidential Canadian supervisory data, we assess whether bank behaviour to maximize shareholder value can amplify a hypothetical stress scenario.

• Occasionally Binding Constraints in Large Models: A Review of Solution Methods

  Staff Discussion Paper 2021-5 Jonathan Swarbrick

  Solving macroeconomic models is difficult. One challenge is the occasionally binding constraint of the zero lower bound on nominal interest rates. This paper reviews various ways to solve models that include this feature.

• A Generalized Endogenous Grid Method for Default Risk Models

  Staff Working Paper 2021-11 Youngsoo Jang, Soyoung Lee

  Models with default options are hard to solve. We propose an extension of the endogenous grid method that solves default risk models more efficiently and accurately.

• Allocative Efficiency and Aggregate Productivity Growth in Canada and the United States

  Staff Working Paper 2021-1 Lin Shao, Rongsheng Tang

  The lack of improvement in allocative efficiency plays a quantitatively important role in the productivity slowdown in the United States and the widening Canada–US productivity gap.
