This paper uses arbitrage arguments to calculate the market value of riskless after-tax cash flows. The market value equals the present value of riskless after-tax cash flows discounted at the after-corporate-tax riskless interest rate. The market value equals the adjusted present value of riskless after-tax cash flows only when the incremental debt used in the adjusted present value calculations equals the market value of the remaining after-tax cash flows. Also, the analysis provides valuation formulas when interest and tax rates are certain but not uniform and when interest rates are uncertain.

The macro literature presents conflicting evidence on the effects of price controls. In this study, the fact that the macro-economic effect of wage and price controls is the aggregation of the micro-economic effects is used to implement a different approach to measure the effects of price controls. The effect of price controls is inferred from examining the impact of discretionary regulatory decisions on the equity values of individual firms during Phase II of Nixon's Economic Stabilization Program. The empirical results indicate that violators of the regulations incurred significant abnormal losses that were unrelated to the explicit penalties. This suggests that implicit penalties were imposed on offending firms. The analysis of price increase decisions provides weak evidence that these Price Commission decisions had an impact on equity values.

This paper provides empirical estimates of the stock market reaction to tender offers, both successful and unsuccessful. The impact of the tender offer on the returns to stockholders of both bidding and target firms is examined. The evidence indicates that for the twelve months prior to the tender offer stockholders of bidding firms earn significant positive abnormal returns. In the month of the offer, only successful bidders earn significant positive abnormal returns. Stockholders of both successful and unsuccessful targe firms earn large positive abnormal returns from tender offers, and most of these returns occur in the month of the offer. For all classes of firms, there is no significant post-offer market reaction. The market reaction to ‘clean-up’ tender offers is also estimated and target stockholders again earn significant positive abnormal returns.

This paper examines the effect of unionization on the profitability of firms. Abnormal monthly common stock returns for a sample of 253 NYSE-listed firms are estimated for the month in which the union petitions for an election and for the month in which the National Labor Relations Board certifies the election outcome. The results suggest that unionization, on average, is associated with a reduction in equity value. When unions win an election, the average loss associated with the unionization drive is 3.8 percent of equity value. When unions lose an election, there is an average net reduction of 1.3 percent in the equity value of the firm.
