Extreme value theory (EVT) has been applied in fields such as hydrology and insurance. It is a tool used to consider probabilities associated with extreme and thus rare events. EVT is useful in modelling the impact of crashes or situations of extreme stress on investor portfolios.

In this issue, Bank staff discuss recent developments in experimental macroeconomics, research results on price-level and unemployment thresholds in forward guidance, and the spillover effects of quantitative easing in advance economies. Articles also explore the competitiveness strategies of Canadian firms as well as their use of financial derivatives.

An important channel in the transmission of monetary policy is the relationship between the short-term policy rate and long-term interest rates. Using a new term-structure model, the authors show that the variation in long-term interest rates over time consists of two components: one representing investor expectations of future policy rates, and another reflecting a term-structure risk premium that compensates investors for holding a risky asset. The time variation in the term-structure risk premium is countercyclical and largely determined by global macroeconomic conditions. As a result, long-term rates are pushed up during recessions and down during times of expansion. This is an important phenomenon that central banks need to take into account when using short-term rates as a policy tool.

To better understand the dynamics of the Chinese economy and its interaction with the global economy, the authors incorporate China into an existing model for the G-3 economies (i.e., the United States, the euro area, and Japan), paying particular attention to modelling the exchange rate and monetary policy in China.

Credit derivatives are a useful tool for lenders who want to reduce their exposure to a particular borrower but are unwilling to sell their claims on that borrower. Without actually transferring ownership of the underlying assets, these contracts transfer risk from one counterparty to another. Commercial banks are the major participants in this growing market, using these transactions to diversify their portfolios of loans and other risky assets. The authors examine the size and workings of this relatively new market and discuss the potential of these transactions for distorting existing incentives for risk management and risk monitoring.

Although the standard of living of Canadians has improved as a result of terms-of-trade gains created by the sharp rise in real commodity prices over the past five years or so, the commodity-price increase, combined with an exchange rate appreciation and real income gain, triggered structural adjustments by altering underlying economic incentives. The frictions generated in adjusting to the relative price shock have likely contributed to hold back aggregate productivity growth. Dupuis and Marcil examine the structural adjustments that have been required-in particular, the resource reallocation among the different sectors of the economy-and its effects on employment, output, and productivity, as well as the responses of final domestic demand and external trade flows.

The size of China’s financial system raises the possibility that the liberalization of its capital account could have a large effect on the global financial system. This paper provides a counterfactual scenario analysis that estimates what the size and direction of China’s overseas portfolio investments would have been in 2015 if China had had no restrictions on these outflows.

This paper provides a comprehensive overview of Canada’s Large Value Transfer System (LVTS).

We evaluate, both empirically and theoretically, the spillover effects that debt-financed fiscal policy interventions of the United States have on other economies. We consider a two-country model with international portfolio rebalancing effects. We show that US fiscal expansions would increase global long-term rates and hinder economic activity in the rest of the world.
