ON THE FUNCTIONAL FORM OF EARNINGS AND STOCK PRICES: INTERNATIONAL EVIDENCE AND IMPLICATIONS FOR THE E/P ANOMALY

This paper examines the functional form of earnings and stock prices on US and Finnish stock markets. Although the functional specification of the components of financial ratios based on purely accounting numbers has received considerable attention, the functional form of earnings and stock prices has not been investigated carefully enough. This investigation is, however, important because of the common use of E/P ratio in financial statement analysis. The empirical evidence provided by this study indicates that the proportional relationship between earnings and stock prices is rejected in both countries. In addition, it is discovered that this deviation from proportionality is a major factor producing the so-called E/P anomaly in these two countries.     

R/S analysis of foreign exchange rates under two international monetary regimes

The purpose of this study is to examine empirically the behavior of foreign exchange markets during the most recent experiences with fixed and flexible rates. Specifically, this study explores the possibility that long-term dependence is present in the exchange rate series for the British pound, French franc, and German mark in terms of the U.S. dollar. Using R/S analysis, positive long-term dependence is uncovered for each exchange rate during the flexible regime but negative dependence is found in the fixed period.
