Steps in Applying Extreme Value Theory to Finance: A Review
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. -

Approaches to Current Stock Market Valuations
The increase in North American stock prices in 1999 and early 2000 has generated interest in the valuation assumptions that would make these price levels sustainable. Here, commonly used valuation techniques are applied to stock markets in Canada and the United States. For the comparative yield approach, real interest rates (rather than nominal rates) are preferred as the comparator of choice to yields on stock market indexes. The spreads between real interest rates and stock market yields have generally increased over the last two years. The dividend-discount model (DDM) approach provides an analytic linkage between the equity-risk premium and the expected growth of dividends. It suggests that market values (measured at the end of February 2000) could be sustained only by rapid growth of dividends in the future or by the continued assumption of an uncharacteristically low risk premium on equity. The spectacular rise in the value of technology stocks in 1999 is noted (Chart 4), and then the valuation measures for the Canadian stock market excluding the technology sector are examined. When this is done with the comparative yield approach, yield spreads are slightly lower, and for the DDM approach, one does not need to assume as high a growth of dividends or as low a risk premium to validate market valuations. Two effects of the "new economy" on the stock market are noted. One is the lowering of dividend yields, as new-economy technology companies tend to have a high reinvestment rate and a low dividend payout rate. Another relates to the potential for a higher track for the economy's productivity growth, which would mean that higher-than-historical assumptions about future earnings growth would be more plausible. Several explanations for the decline in risk premiums on equity are considered. While short-term volatility in the stock market has, if anything, increased in recent years, low inflation and improved economic performance, along with demographics and investor preferences, may have contributed to a decline in the risk premium demanded by investors. A scenario of rapid growth of dividends in the near term slowing to historical norms in the longer term is examined. While this approach can go partway towards explaining high stock market valuations, it requires assumptions that are outside historical experience. -
Modelling Risk Premiums in Equity and Foreign Exchange Markets
The observed predictability of excess returns in equity and foreign exchange markets has largely been attributed to the presence of time-varying risk premiums in these markets. For example, excess equity returns were found to be explained by various financial and economic variables. -

The Corporate Bond Market in Canada
The Canadian corporate bond market has experienced a renaissance, in recent years, against a background of low inflation, reduced public borrowing, and the lowest levels of long-term interest rates in a generation. The authors examine the influences shaping the market and also compare the Canadian market with those of other countries. The increased level of activity in the market has been accompanied by the development of new products and by greater investor interest in instruments with higher returns and higher credit risk. A more dynamic Canadian corporate bond market is a welcome development since it offers borrowers an alternative source of funds, especially companies that have typically relied on the banking system and on the U.S. corporate bond market for financings involving higher levels of credit risk. -

Markets for Government of Canada Securities in the 1990s: Liquidity and Cross-Country Comparisons
In this article, the author reviews the factors behind the recent evolution of liquidity in the market for Government of Canada (GoC) securities. He finds that liquidity has been supported by changes in the structure of the market, notably the introduction and increasing size of benchmark bond issues. He also notes that while the GoC bond market has generally benefited from changes in market structure, liquidity in the treasury bill market has decreased since the mid-1990s, largely because of the declining supply of these securities. This article also presents some comparisons of liquidity in the government securities markets of other industrialized countries and finds that liquidity in the Canadian market appears to compare favourably with all but the large U.S. Treasury market. -
Estimating One-Factor Models of Short-Term Interest Rates
There currently exists in the literature several continuous-time one-factor models for short-term interest rates. This paper considers a wide range of these models that are nested into one general model. These models are approximated using both a discrete-time model and a model that accounts for aggregation effects over time, and are estimated by both the […] -
The Information Content of Interest Rate Futures Options
Options prices are being increasingly employed to extract market expectations and views about monetary policy. In this paper, eurodollar options are monitored to examine the evolution of market sentiment over the possible future values of eurodollar rates. Risk-neutral probability functions are employed to synopsize the information contained in the prices of euro/dollar futures options. Several […] -

Recent Initiatives in the Canadian Market for Government of Canada Securities
The initiatives reviewed by the author were undertaken to ensure a liquid and well-functioning market for Government of Canada securities in light of the significant shift in the government's financial position. They include changes made in 1998 by the Bank of Canada and the government to the rules governing auctions and to the Bank's surveillance of the auction process, changes to the treasury bill and bond programs, and implementation of a pilot buyback program for Government of Canada marketable bonds. In addition, the Investment Dealers Association of Canada adopted a code of conduct for the secondary market. These initiatives were well received by the market and appear to have had a positive impact. The Bank and the government are, however, continuing their search for ways to maintain and enhance the efficiency of this market. -

Recent Developments in Global Commodity Prices: Implications for Canada
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.
