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.

This paper examines the effects of unexpected inflation on the returns to the common stock of companies with different short-term monetary positions, and different long-term monetary positions, and different amounts of nominal tax shields. Unlike most previous studies of the effects of nominal contracting, we distinguish between expected and unexpected inflation in our tests. Surprisingly, over the 1947-79 period there is little evidence that stockholders of net debtor firms benefit from unexpected inflation relative to the stockholders of net creditor firms. We conclude that wealth effects caused by unexpected inflation are not an important factor in explaining the behavior of stock prices.
