How are regional cost shocks passed through into global prices? We investigate the role of short-run capacity constraints and show that they can induce stark non-linearities in the pass-through. We highlight this effect for the market for ammonia, a commodity produced largely from natural gas.

The authors examine the recent evolution of commodity prices. They discuss the factors behind the price declines that occurred between the summer of 1997 and the end of 1998, including the key supply factors and the drop in Asian demand caused by that region's concurrent financial and economic crisis. They then review the effects of the reduction in world commodity prices on economic activity in Canada. They point out that the depreciation of the Canadian dollar against the U.S. dollar, together with the continued strength of the U.S. economy, has partly offset the negative effects on Canadian aggregate demand.

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.

This paper shows that real effective exchange rate (REER) regressions, the standard approach for estimating the response of aggregate exports to exchange rate changes, imply biased estimates of the underlying elasticities. We provide a new aggregate regression specification that is consistent with bilateral trade flows micro-founded by the gravity equation.

Bank of Canada Governor Tiff Macklem discusses how artificial intelligence could impact the economy, and outlines some of the implications for monetary policy.

The Reports section of the Financial System Review examines selected issues of relevance to the Canadian and global financial systems. The December 2015 issue features two reports on significant developments in the financial system related to household finances: the importance of residential mortgage securitization for Canadian housing finance and the changing patterns of indebtedness of Canadian households.

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.

Standard monetary models adopt an infinite horizon with discounting. Testing these models in the lab requires implementing this horizon within a limited time frame. We compare three approaches to such an implementation and discuss their relative advantages.

This issue features a summary of the Bank’s annual conference, which this year dealt with financial globalization, and three articles that present research by Bank staff on Canada’s mortgage market, the role of adverse selection in financial crises, and payment networks.

Consumption inequality and a low interest rate environment are two important trends in today’s economy. But the implications they may have—and how those implications interact—within different monetary policy frameworks are not well understood. We study the ranking of alternative frameworks that take these trends into account.
