The Information Content of Stock Prices and Earnings of Non‐U.S. Firms: A Simultaneous Equations Approach

This study uses a simultaneous equations approach to examine the price‐earnings relationship of non‐U.S. firms that directly list their securities in U.S. capital markets or trade as American Depository Receipts (ADRs). The Hausman test shows that price changes and earnings changes are endogenously determined, thus the simultaneous equations approach is used to estimate the earnings response coefficient (ERC) and the returns response coefficient (RRC). Under the ordinary least squares (OLS) estimation, the parameter estimates are biased downward because the OLS fails to correct for endogeneity. In general, our results show that the joint estimation procedure mitigates some of the single‐equation bias. The estimated ERC and the RRC are higher under the three stage least regression (3SLS) than under the OLS regression. In addition, the product of the ERC and the RRC coefficients approaches its theoretical value of one when using the 3SLS estimation. The evidence also shows that institutional factors affect the way the market value information for these firms. We find that the ERC and RRC are insignificant for the common law non‐ADR firms and significantly positive for common law ADR firms.
