Output and Expected Returns- a multicountry study

gratefully acknowledged. This paper analyzes whether the price-output ratio (the cpy-ratio) predicts real stock re-turns in twelve OECD countries. The cpy-ratio is a ratio of a share price to a macroeco-nomic variable. Traditionally, either ratios of purely financial indicators, ratios of purely macroeconomic indicators, or ratios of macroeconomic indicators to wealth have been used to predict returns. However, if share prices are mean reverting, and thus contain a predictable component, and predictability of returns is related to the macroeconomic environment that ultimately determines the investment opportunities, a ratio of a share price to a macroeconomic variable could be believed to predict returns. The analyses reveal that the cpy-ratios do indeed predict future stock returns in most of the countries that are studied
