• 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.

• Assessing global potential output growth and the US neutral rate: April 2022

  Staff Analytical Note 2022-4 Kyle Boutilier, Thomas J. Carter, Xin Scott Chen, Eshini Ekanayake, Louis Poirier, Peter Shannon, Akash Uppal, Lin Xiang

  We expect global potential output growth to increase from 2.7% in 2021 to 2.9% by 2024. Compared with the April 2021 assessment, global potential output growth is marginally slower. The current range for the US neutral rate is 2% to 3%, 0.25 percentage points higher than staff’s last assessment.

• ToTEM III: The Bank of Canada’s Main DSGE Model for Projection and Policy Analysis

  Technical Report No. 119 Paul Corrigan, Hélène Desgagnés, José Dorich, Vadym Lepetyuk, Wataru Miyamoto, Yang Zhang

  ToTEM III is the most recent generation of the Bank of Canada’s main dynamic stochastic general equilibrium model for projection and policy analysis. The model helps Bank staff tell clear and coherent stories about the Canadian economy’s current state and future evolution.

• Can regulating bank capital help prevent and mitigate financial downturns?

  Staff Analytical Note 2021-12 Alejandro García, Josef Schroth

  Countercyclical capital buffers are regulatory measures developed in response to the global financial crisis of 2008–09. This note focuses on how time-varying capital buffers can improve financial stability in Canada

• Assessing global potential output growth and the US neutral rate: April 2021

  Staff Analytical Note 2021-5 Thomas J. Carter, Xin Scott Chen, Ali Jaffery, Christopher Hajzler, Jonathan Lachaine, Peter Shannon, Subrata Sarker, Graeme Westwood, Beiling Yan

  We expect global potential output growth to rise to 3 percent by 2022. Relative to the last assessment in October 2020, potential output growth has been revised up across all the regions. The range of the US neutral rate remains unchanged relative to the autumn 2020 assessment.

• A Macroeconomic Model of an Epidemic with Silent Transmission and Endogenous Self-isolation

  Staff Working Paper 2020-50 Antonio Diez de los Rios

  We study the interaction between epidemics and economic decisions in a model that has silent transmission of the virus. We find that rational behaviour strongly diminishes the severity of the epidemic but worsens the economic recession. We also find that the detection and isolation of not only symptomatic individuals but also those who are infected and asymptomatic or mildly symptomatic can reduce the severity of the recession caused by the pandemic.

• Assessing Global Potential Output Growth: October 2020

  Staff Discussion Paper 2020-10 Xin Scott Chen, Ali Jaffery, Guillaume Nolin, Karim Salhab, Peter Shannon, Subrata Sarker

  This paper presents updated estimates of potential output growth for the global economy through 2022. Global potential output growth is expected to decline sharply in the aftermath of the COVID-19 pandemic and recover partially by the end of the projection horizon of the October 2020 Monetary Policy Report.

• Identifying Aggregate Shocks with Micro-level Heterogeneity: Financial Shocks and Investment Fluctuation

  Staff Working Paper 2020-17 Xing Guo

  This paper identifies aggregate financial shocks and quantifies their effects on business investment based on an estimated DSGE model with firm-level heterogeneity. On average, financial shocks contribute only 3% of the variation in U.S. public firms’ aggregate investment.

• The Power of Helicopter Money Revisited: A New Keynesian Perspective

  Staff Discussion Paper 2020-1 Thomas J. Carter, Rhys R. Mendes

  We analyze money financing of fiscal transfers (helicopter money) in two simple New Keynesian models: a “textbook” model in which all money is non-interest-bearing (e.g., all money is currency), and a more realistic model with interest-bearing reserves.
