Unlike other investments in the U.S., research and development budgets are not depreciated but expensed. Thus, pre-tax reported earnings fluctuate dollar-for-dollar with changes in R&D budgets. Because executives know more about the firm than outsiders, they may adjust R&D budgets in order to manage accounting earnings and stock prices. Discretionary changes in R&D may also reflect managerial incentives, taxes, and free cash flow. We study a panel of 100 U.S. companies with large R&D budgets for the decade between 1977 and 1986. On average, R&D budget adjustments reduce the anticipated gap between analysts' earnings forecasts and reported income. In the cross-section of firms, more gap closure is associated with high trading volume and high business risk. Less earnings management occurs if the CEO and institutional investors own an important fraction of the shares.

This paper provides empirical evidence that takeovers can facilitate the efficient redeployment of assets of bankrupt firms. Bidders for bankrupt firms are generally in related industries and often have some prior relationship to the target, suggesting they are well informed with respect to both the value and best use of the target's assets. For a sample of 55 acquisitions in Chapter 11, we find that firms merged with bankrupt targets show significant improvements in operating performance, while matching non-bankrupt transactions show no significant improvement. We also find positive and significant abnormal stock returns for the bidder and bankrupt target at the announcement of the acquisition.Journal of Economic LiteratureClassification Numbers: G33, G34.

We examine parent-subsidiary mergers, transactions that do not entail arm's length bargaining or a change in control. These mergers are typically followed by considerable restructuring of subsidiaries. Minority and parent returns are not significantly different from returns at third party buyouts of parent-controlled subsidiaries, transactions that entail arm's length negotiations and a change in control. Buyer returns are negative, consistent with overbidding. We conclude that parent-subsidiary mergers facilitate corporate restructuring, foster the reallocation of resources toward higher valued uses, and increase value for both parent and subsidiary.

This article analyzes the dynamics of joint labor force behavior of older couples in the United States. Using the Retirement History Survey (RHS) I analyze the determinants of joint retirement and the effect of one spouse's labor force status on the labor force transitions of the other spouse. The results reveal strong associations between the labor force transition probabilities of one spouse and the labor force status of the other spouse. These result from structural differences in exit and entry behavior by the spouse's status. Several lagged endogenous variables have substantial effects on behavior even after controlling for unobserved heterogeneity.

This study extends previous research that documents a stock price reaction leading accounting earnings. The primary issue is that prior studies use a naive earnings expectation model (random walk) as the benchmark for the information content of lagged returns and do not adequately address the “incremental” information content of lagged returns. This study identifies and estimates firm‐specific models of earnings to control directly for the autocorrelation in earnings. The explanatory power of lagged prices with respect to this earnings residual is investigated using both a multiple regression model of lagged returns and a multiple time‐series vector autoregressive model. In‐sample estimation of the models provides clear evidence that stock prices impound information about future earnings incremental to the information contained in historical earnings data. Holdout period analysis of the earnings forecasts from these lagged return models finds that both models outperform the naive seasonal random walk expectation, but neither model outperforms the more sophisticated Box‐Jenkins forecasts. On an individual firm basis, earnings forecasts supplemented with the lagged return data tend to be less precise than the Box‐Jenkins forecasts, but the price‐based models demonstrate an ability to rank the earnings forecast errors from the time‐series models. The analysis helps to characterize the limitations of lagged returns as a means of predicting future earnings innovations.

Fama (1977) and Miller (1977) predict that one minus the corporate tax rate will equate after tax yields from comparable taxable and tax-exempt bonds. Empirical evidence shows that long-term tax-exempt yields are higher than theory predicts. Two popular explanations for this empirical puzzle are that, relative to taxable bonds, municipal bonds bear more default risk and include costly call options. I study U.S. government secured municipal bond yields which are effectively default-free and noncallable. These municipal yields display the same tendency to be too high. I conclude that differential default risk and call options do not explain the municipal bond puzzle.
