I use a large sample of jobs from the National Longitudinal Survey of Youth to examine job mobility patterns and to evaluate theories of interfirm worker mobility There are three main findings. First, the monthly hazard of job ending is not monotonically decreasing in tenure as most earlier work using annual data has found, but it increases to a maximum at 3 months and declines thereafter. Second, mobility is strongly positively related to the frequency of job change prior to the start of the job. Finally, job change in the most recent year prior to the start of the job is more strongly related than earlier job change to mobility on the current job.

Abstract. The occurrence of conglomerate mergers is somewhat of a mystery. This paper presents a model demonstrating a tax motive for these mergers. Specifically, conglomerate mergers are unions between firms with not highly correlated earning prospects—when one merger partner underperforms (earning inadequate income) in the future, the other is likely to overperform. By amalgamating such firms into common taxable entities, conglomerate mergers create several tax benefits: (1) improved chances that future tax write‐offs and credits will be immediately utilized in full rather than deferred as less valuable loss‐carryforwards; (2) reduced chances that tax write‐offs and credits are permanently lost in bankruptcy; and (3) an enhanced ability to write off the interest on additional debt Empirical support for these results are presented. Given (1) and (2), the U.S. tax law changes in 1981 and 1986 would respectively encourage and discourage merger activity, outcomes that were indeed observed. Consistent with (3), a cross‐sectional examination of U.S. mergers shows that mergers were more likely to increase consolidated leverage when earnings of the predecessor firms were less highly correlated. Nontax‐related bankruptcy costs are not specifically modeled, but firms whose potential tax write‐offs and credits are larger tend to have lower preference for leverage. Thus, in many instances diminishing bankruptcy risk is not a motive for conglomeration, but full utilization of tax write‐offs is. Résumé. L'occurrence de certaines fusions par conglomérat demeure toujours inexpliquée. L'auteur expose un modèle attribuant les fusions de cette nature à des motifs fiscaux. Selon ce modèle, il en serait ainsi lorsque les fusions par conglomérat touchent des entreprises dont les perspectives de gains ne présentent pas de corrélation très élevée — le rendement escompté de l'une des entreprises qui fusionnent est plutôt mince (ses bénéfices étant insatisfaisants), alors que le rendement escompté de l'autre est assez exceptionnel. Le regroupement de ces entreprises sous forme d'entités imposables grâce à la fusion par conglomérat donnerait lieu, toujours selon ce modèle, aux avantages fiscaux suivants: (1) l'augmentation des chances que les éléments susceptibles d'être passés en charges aux fins de l'impôt ou de donner droit à des dégrèvements soient aussitôt utilisés intégralement plutôt que de faire l'objet de reports de perte prospectifs dont la valeur serait diminuée; (2) la réduction des risques que les éléments susceptibles d'être passés en charges aux fins de l'impôt ou de donner droit à des dégrèvements soient perdus à jamais à la suite d'une faillite; et (3) la possibilité accrue de passer en charges l'intérêt sur la dette supplémentaire. Les constatations empiriques confirment ces hypothèses. Étant donné les hypothèses 1 et 2, les modifications apportées à la loi fiscale aux États‐Unis en 1981 et 1986 encourageraient, dans le premier cas, et décourageraient, dans le second, les fusions, ce qui a été observé dans les faits. Conformément à l'hypothèse 3, un examen transversal des fusions ayant eu lieu aux États‐Unis a démontré qu'elles étaient davantage susceptibles d'augmenter l'effet de levier consolidé lorsque les bénéfices des entreprises constituantes présentaient une corrélation moins élevée. Les coûts des faillites qui ne sont pas d'ordre fiscal ne sont pas spécifiquement intégrés au modèle, mais les entreprises dont les possibilités de passation en charges et de dégrèvements sont plus élevées ont tendance à afficher une préférence moins prononcée pour l'effet de levier. À maints égards, donc, la réduction du risque de faillite n'est pas un motif de fusion par conglomérat, tandis que les possibilités de passation en charges le sont.

A two-date rational expectations model is analyzed. At the first date, traders can privately acquire a costly signal that provides imperfect information about a public report that will be issued at the second date. Equilibrium characterizations are provided for the fraction of traders that become informed and the informativeness of the first-date price, as well as the price change variance and the expected trading volume at the second date. Comparative statics identify how the above variables are influenced by changes in the information content of the public report, and in particular how market phenomena at the public release date are influenced by endogenous prior information acquisition and trading in response to the forthcoming public release.

This study reexamines competition, cost structure, and growth opportunities effects on earnings response coefficients and extends this literature in several ways. First, it presents a more refined theoretical motivation for investigating competition and cost structure effects. Second, it introduces new economic factor proxies that confirm prior findings with respect to competition but differ from prior findings with respect to cost structure and growth opportunities. Overall the evidence suggests that accounting earnings reflect information about future economic rents generated by firms' assets-in-place. The evidence also suggests, contrary to prior studies, that accounting earnings are not very informative about firms' growth opportunities.

We examine the lead–lag relation between intraday spot and futures prices for a stock index where the component stocks are floor traded while the futures contract is screen traded. We find that futures prices lead spot prices by nearly 20 min. This is much longer than in markets where both the index and index futures are floor traded. We show that this lead–lag relation is unlikely to be an artifact of differences in liquidity between the spot and futures markets. These results are consistent with the hypothesis that screen trading accelerates the price discovery process. Journal of Economic Literature Classification Numbers: F33, G15, G20, O31.

This paper considers the extent to which loan commitments mitigate the problems of information monopolies that arise when the firm contracts with a private lender. Loan commitments in conjunction with short-term debt often provide the firm with superior investment incentives by influencing both the states in which bargaining occurs as well as the outcomes from bargaining. Commitment contracts are particularly valuable when there is a high likelihood that information about the firm will be publicly revealed ex post. We also identify circumstances under which the firm foregoes commitment financing, relying on short-term debt instead. Journal of Economic Literature Classification Numbers G21, G32, D82.

Multi-bank holding companies file detailed financial statements on their subsidiary banks. The availability of these data allows for an empirical examination of the relation between accounting-based performance and personnel decision for lower-level managers. For our sample of Texas banks, we find that turnover of subsidiary bank managers is negatively related to subsidiary performance, while promotions are positively related to performance. Holding own-bank performance constant, turnover increases with holding-company performance, which is consistent with the view that turnover decisions are based on performance relative to a firm-specification benchmark.

We present a qualitative and quantitative analysis of the standard growth model modified to include precautionary saving motives and liquidity constraints. We address the impact on the aggregate saving rate, the importance of asset trading to individuals, and the relative inequality of wealth and income distributions.

We present a bargaining model of union contract negotiations, in which the union decides between two threats: the union can strike, or it can continue to work under the expired contract. The model makes predictions about the level of dispute activity and the form disputes take. Strike incidence increases as the strike threat becomes more attractive, because of low unemployment or a real wage drop. We test these predictions by estimating logistic models of dispute incidence and dispute composition for negotiations from 1970 to 1989. We find support for the model's key predictions, but these associations are weaker after 1981.
