Long- and short-term interest rates in 19 countries: Tests of cointegration and parameter instability

This paper examines the long-run relationship between short-term and long-term interest rates (both nominal and real) in 19 countries, and explores the possibility that the relationship is statistically stable using Lc, MeanF, and SupF statistics suggested by Hansen [1992]. Empirical results obtained from various cointegration techniques (Johansen, Phillips and Hansen, Stock and Watson, and Park) and quarterly data (1973–1998) show considerable support for the expectations hypothesis in all countries (except the United Kingdom). In a majority of cases, it is also found that a stable relationship exists between the short-term and long-term interest rates.     

Equity market valuation,systematic risk and monetary policy

This study examines the relationship between equity market valuation and risk indicators that portend economic downswings. The indicators are implied options volatility, Treasury-Eurodollar (TED) spread and exchange rate. While implied volatility captures market risk in that it reflects the fear factor embedded in the price of an option, TED spread reflects the default risk premium that is priced into a key short-term credit instrument. Equity markets often show a tendency to reflect the incidence of these risk factors. And because they provide valuable information about the health of the economy, many have argued that equity market valuation be taken into account in the formulation of monetary policy. Results of this study not only show a statistically significant inverse relationship between the stock market and these risk factors, but also evidence of a cointegration. In a variance decomposition of the series, we find that equity valuation is a major contributor to the forecast error variances of each of the risk indicators, a finding that lends tacit support to the argument that risk indicators associated with the equity market be considered in monetary policy decisions.
