The four essays published here provide a useful overview for anyone interested in understanding the issues and policy environment surrounding financial system stability.

Explanations of changes in asset prices as being due to exogenous changes in risk appetite, although arguably controversial, have been popular in the financial community and have also received some attention in attempts to account for recent financial crises. Operational versions of these explanations are based on the assumption that changes in asset prices can be decomposed into a part that can be attributed to changes in riskiness and a part attributable to changes in risk aversion, and that some quantitative measure can capture these effects in isolation.

The authors identify the fundamentals behind the dynamics of the U.S. stock market over the past 30 years. They specify a structural vector-error-correction model following the methodology of King, Plosser, Stock, and Watson (1991).

The author describes the rapid development of the syndicated corporate loan market in the 1990s. He explores the historical forces that led to the development of the contemporary U.S. syndicated loan market, which is effectively a hybrid of the investment banking and commercial banking worlds.

The authors develop an index of financial stress for the Canadian financial system. Stress is defined as the force exerted on economic agents by uncertainty and changing expectations of loss in financial markets and institutions.

The author examines the role of collateral in an environment where lenders and borrowers possess identical information and similar beliefs about its future value. Using option-pricing techniques, he shows that a secured loan contract is equivalent to a regular bond and an embedded option to the borrower to default.

The authors examine how the valuation multiples assigned to the equity of Canadian-listed firms compare with the equity of comparable firms listed in the United States. They find that Canadian-listed firms trade at a discount to U.S.-listed firms across a range of valuation measures.

The authors develop a new methodology to investigate how crises cause the relationship between financial variables to change. Two possible sources of increased co-movement between markets during high-variance episodes are considered: larger common shocks operating through standard market linkages, and a structural change in the propagation of shocks between markets, called "shift contagion."

In a recent attempt to account for the equity-premium puzzle within a representative-agent model, Cecchetti, Lam, and Mark (2000) relax the assumption of rational expectations and in its place use the assumption of distorted beliefs. The author shows that the explanatory power of the distorted beliefs model is due to an inconsistency in the model and that an attempt to remove this inconsistency removes the model's explanatory power.

Awareness of operational risk has increased greatly in recent years, both at individual financial institutions and for payment, clearing, and settlement systems (PCSS). PCSS consist of networks of interconnected elements (i.e., central operators, participants, and settlement agents); operational problems at any one of the key elements have the potential to disrupt the system as a whole and negatively affect financial stability.
