The Term Structure of Interest Rates and Expected Economic Growth

Abstract

Many papers have documented the positive relationship between the slope of the yield curve and future real economic activity in different countries and different time periods. One explanation for this economic link is based on monetary policy. However, empirical evidence (Estrella and Hardouvelis, 1991; Plosser and Rouwenhorst, 1994; Estrella and Mishkin, 1997; Moersch, 1996a,b; Kozicki, 1997; Dotsey, 1998; Ivanova et al., 2000) has shown that monetary policy does not appear to be the only source of the predictive power of the term spread. Therefore, the spread reflects other economic conditions beyond actions taken by monetary authorities. According to Harvey (1988), the forecasting ability of the term spread on economic growth is due to the fact that interest rates reflect the expectations of investors about the future economic situation when deciding about their plans for consumption and investment. Harvey (1988) uses the Consumption-Based Asset Pricing Model (CCAPM) to derive a forecasting equation that relates the slope of the term structure of interest rates to expected consumption growth. Harvey's model has been tested in several countries using ex post consumption or output growth as proxies of expected consumption growth. This paper complements and extends the evidence of Harvey's model by testing it for the case of Spain and by using a measure of expected consumption growth rather than proxies for the investors' expectations. The variables used are the Consumer Confidence Indicator and the Economic Sentiment Indicator (elaborated by the European Commission) that directly stand for the expectations of economic agents about the future economic situation in the next twelve months.
