Firms that alter their divisional configurations on average increase shareholder wealth. Gains appear to come from information about investment opportunities and increases in efficiency. Performance before the restructurings suggests poorly organized firms are motivated by market pressures to change their organizations. Change also occurs in healthy firms as part of the growth process. Restructuring often occurs where there is no evidence of takeover threats. While stock prices increase around the restructurings, there is a contemporaneous decline in earnings due to increased expenses. These findings appear inconsistent with the contention that the market pressures managers into focusing on short-run earnings.

The authors study the price elasticity of demand for the common stock of an individual corporation. Despite the prevalance of assumptions that demand is perfectly elastic, there is little, if any, direct evidence in the literature to either support or reject that contention. Consistent with the notion of finite price elasticities, the authors find that the announcement of primary stock offerings by regulated firms depresses their stock prices and little, if any, evidence that this decline is the result of adverse information about future cash flows. Attempts to relate offer announcement effects directly to possible determinants of price elasticities, however, are inconclusive.
