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.

Flight from Safety: How a Change to the Deposit Insurance Limit Affects Households’ Portfolio Allocation Staff Working Paper 2019-29 H. Evren Damar, Reint Gropp, Adi Mordel Deposit insurance protects depositors from failing banks, thus making insured deposits risk-free. When a deposit insurance limit is increased, some deposits that previously were uninsured become insured, thereby increasing the share of risk-free assets in households’ portfolios. This increase cannot simply be undone by households, because to invest in uninsured deposits, a household must first invest in insured deposits up to the limit. This basic insight is the starting point of the analysis in this paper.

Avoiding the Pitfalls: Can Regime-Switching Tests Detect Bubbles? Staff Working Paper 1996-11 Simon van Norden, Robert Vigfusson Work on testing for bubbles has caused much debate, much of which has focussed on methodology. Monte Carlo simulations reported in Evans (1991) showed that standard tests for unit roots and cointegration frequently reject the presence of bubbles even when such bubbles are present by construction. Evans referred to this problem as the pitfall of testing for bubbles.

The Effect of the Federal Reserve’s Tapering Announcements on Emerging Markets Staff Working Paper 2014-50 Vikram Rai, Lena Suchanek The Federal Reserve’s quantitative easing (QE) program has been accompanied by a flow of funds into emerging-market economies (EMEs) in search of higher returns.

Education and Self-Employment: Changes in Earnings and Wealth Inequality Staff Working Paper 2006-40 Yaz Terajima The author quantitatively studies the interaction between education and occupation choices and its implication for the relationship between the changes in earnings inequality and the changes in wealth inequality in the United States over the 1983–2001 period.

A Q-Theory of Banks Staff Working Paper 2021-44 Juliane Beganau, Saki Bigio, Jeremy Majerovitz, Matías Vieyra Using stock market data on banks, we show that the book value of loans recognizes losses with a delay. This delayed accounting is important for regulation because the requirements regulators impose are based on book values.

May 15, 2000 Credibility and Monetary Policy Bank of Canada Review - Spring 2000 Patrick Perrier, Robert Amano A highly credible monetary policy helps to reduce the degree of uncertainty that can surround the objectives of such policy. When the monetary policy pursued by the central bank is credible, the expectations of the public are focused on a target. If the public believes that the Bank will act to bring inflation back to the target, then its expectations will not react so strongly to fluctuating price trends. In turn, fluctuations in inflation, interest rates, output, and employment should be less pronounced than in the absence of such credibility. The adoption of inflation control as a monetary policy objective by some countries has led central banks to take steps to enhance the credibility of monetary policy. For the Bank of Canada, these include * the publication of our Monetary Policy Report each May and November, with formal updates each February and August * the initiation of communications activities across the country * the use of the overnight interest rate as a short-term operating target * the issuing of a press release each time the Bank changes its key rates To date, most of the studies on this topic have concluded that success in keeping inflation within a target range has helped to increase the credibility of Canadian monetary policy. These surveys suggest that expected inflation, which stood at about 5 per cent in 1990, declined to around 2 per cent by 1999 (Chart 1, page 15). Indeed, according to these surveys, for the entire period during which the Bank has had a target range for inflation, expected inflation rates have remained within that range. Inflation expectations have also reacted very little to changes in the total CPI, suggesting that the targets have helped to focus expectations on the target rate and have thus enhanced the credibility of monetary policy (Chart 2, page 16). One particular study shows that the life of collective wage agreements in Canada has been increasing and that the number of such agreements containing cost-of-living adjustment (COLA) clauses has steadily declined. The authors of this study suggest that this may reflect the greater credibility of Canadian monetary policy (Table 1, page 16). The proportion of mortgages with five-year terms is now higher than it was in the mid-1980s, and many financial institutions have been offering 7- to 10-year mortgages. This also suggests that inflation targets have gained credibility. Content Type(s): Publications, Bank of Canada Review articles Topic(s): Recent economic and financial developments

Switching Between Chartists and Fundamentalists: A Markov Regime-Switching Approach Staff Working Paper 1996-1 Robert Vigfusson Since the early 1980s, models based on economic fundamentals have been poor at explaining the movements in the exchange rate (Messe 1990). In response to this problem, Frankel and Froot (1988) developed a model that uses two approaches to forecast the exchange rate: the fundamentalist approach, which bases the forecast on economic fundamentals, and the chartist approach, which bases the forecast on the past behaviour of the exchange rate.
