Shareholder-value maximization and product-market competition

We investigate product-market competition when managers maximizeshareholder value rather than their expected discounted valueof profits. If share-holders are imperfectly informed aboutfuture profitability, shareholder-value maximization can leadto either more or less aggressive product-market strategies.Lower rivals' profits lead investors to believe that the firm'scosts are low relative to those of its rivals and that the industry'sprospects are poor. If the former (latter) inference dominates,each firm tries to lower (raise) its rival's profits to increaseits own stock price. We also consider implications for corporatefinancial structure.
