An efficient matching model of quits and layoffs is developed to account for several empirical regularities. Differences between quits and layoffs over the life and business cycles and across demographic groups are generated by differential rates of general productivity growth. The standard approach to quits and layoffs, based on wage rigidity, is shown to be incapable of accounting for many of the empirical regularities. Although a formal test rejects a structural prediction of the efficient turnover model, the specification does well in predicting both the level of and time-series variation in the fraction of separations labeled quits.

One method of estimating losses resulting from work stoppages is to multiply the total number of man-days lost during disputes by the average product of workers. This statistic can be easily calculated using information typically available from government agencies but has obvious flaws. For example, the behavior of other firms not involved in disputes is ignored. Moreover, when output is durable, the impact on consumption is unknown since inventories can be used as buffers. To assess the importance of these and other considerations, I develop an alternative empirical framework and implement it using data from the British Columbian lumber industry.

This paper discusses the decentralization of production and cost decisions in a multidivisional firm via divisional performance measurement systems based on accounting information. The model firm has a single producing division that supplies goods to several consuming divisions for further processing and sale on external markets. Production is assumed to be characterized, in the long run, by constant returns to scale, and, in the short run, by constant unit variable cost up to a fixed capacity, which imposes a short‐run fixed cost. It is also assumed that the final products sold on external markets face downward sloping demand. The firm's accounting information system transmits a comprehensive record of quantities, revenues, and costs resulting from realized transactions, including the classification of costs between fixed and variable, but transmits no information concerning unrealized production, cost, and revenue possibilities. The paper shows that such information is not sufficient to motivate short‐run profit maximization, which requires the optimal allocation of scarce producing division capacity among the competing demands of the consuming division. However, in the long run, a more positive result is obtained. A class of transfer price mechanisms, termed profit‐sharing systems , leads net‐income maximizing division managers to optimal production decisions and cost ‐efficient technology choices in the long run. Moreover, it is shown that the profit‐sharing transfer price is equal to the “arm's‐length” negotiated price determined by the Nash bargaining solution. Résumé. L'auteur traite de la décentralisation des décisions relatives à la fabrication et aux coûts dans une entreprise à divisions multiples, par l'intermédiaire de systèmes de mesure du rendement divisionnaire fondés sur l'information comptable. L'entreprise type possède une seule division de fabrication qui approvisionne plusieurs divisions consommatrices en produits intermédiaires qui sont retraités par elles et vendus sur les marchés extérieurs. L'auteur suppose que la fabrication se caractérise à long terme par des rendements d'échelle constants, et à court terme par des coûts variables unitaires constants au regard d'une capacité établie qui suppose un coût fixe à court terme. Il pose également l'hypothèse que la demande pour les produits finis vendus sur les marchés extérieurs connaît un déclin. Le système d'information comptable de l'entreprise comporte un registre complet des renseignements concernant les quantités fabriquées, les produits d'exploitation et les coûts relatifs aux opérations ainsi conclues, avec classification des coûts fixes et varibles, mais ne livre aucune information relative aux possibilités de fabrication, de coûts et de produits d'exploitation auxquelles l'entreprise a renoncé. L'auteur montre que cette information ne suffit pas à motiver la maximisation des bénéfices à court terme, qui exige l'affectation optimale des capacités de fabrication limitées de la division de fabrication entre les divisions consommatrices dont les demandes sont en concurrence. À long terme, l'on obtient cependant un résultat plus positif. En effet, un ensemble de mécanismes touchant l'établissement des prix de cession, qu l'on appelle les systèmes d'intéressement, amène les gestionnaires qui cherchent à maximiser le bénéfice net de leur division à des décisions optimales de fabrication et à des choix économiques rationnels en matière de technologie. On constate en outre que le prix de cession en système d'intéressement est équivalent au prix négocié « sans lien de dépendance » déterminé selon la solution de négociation de Nash.

Comparative advantage and the division of labor make geographic concentration of production within a nation profitable and cause many cities to be specialized in one or a few main industries. Specialized cities, however, suffer greater unemployment risk. The theory of compensating wage differentials predicts that individuals living in more specialized cities will be compensated in the form of higher wage rates. We study the effects of specialization on wages and unemployment in the United States. We find evidence of compensating wage differentials. That firms choose to locate in more specialized, higher-wage cities is indirect evidence of the gains to specialization.

A portfolio formed from a given list of assets is defined as a numeraire portfolio for the list if (a) it is self-financing, (b) its value is always positive, and (c) zero is always the best conditional forecast of the numeraire-dominated rate of return of every asset on the list. The numeraire portfolio exists if and only if there are no profit opportunities from trading assets on the list. For a sample list of heterogeneous assets (NYSE size-quintile portfolios, corporate bonds, and short-term bills), numeraire-dominated returns are similar to market-model forecast errors and, as abnormal return measures, clearly dominate market-adjusted returns.

The "job-stopping" process of older workers often includes some combination of postcareer "bridge" employment, partial retirement, and reverse retirement. Fewer than two-fifths of household heads retire directly from career jobs, over half partially retire at some point in their working lives, and a quarter reenter the labor force after initially retiring. In addition, postcareer employment is frequently located outside the industry and occupation of the career job, and there are important differences in postcareer labor force experiences by gender, permanent income, and career-job pension status.

Recent theories of corporate organization hold that mutually owned firms arise to remedy agency problems associated with ownership by a separate class of stockholders. We propose an alternative theory of mutuality, in which mutuals arise endogenously as a self-selection mechanism to cope with adverse selection and systematic risk. This theory makes predictions about the nature of customer contracts and the pattern of dividend payments adopted by mutuals. We do not systematically test this theory against others. But the behavior of the Farm Credit System, a large financial mutual, is shown to be more in accord with our theory.

Law and politics affect the financial structure of the public corporation, perhaps as much as economics. Law restricts financial institutions from holding large equity blocks and from networking the small blocks they do own. Impetus for these restrictions came from several sources: a public-spirited belief that financial stability would be fostered by financial fragmentation, American federalism (each state created its own insular set of financial institutions), rivalries between groups of financial institutions, and popular mistrust of powerful private financial institutions. The stability of many of these rules also derives from the political resistance that one would expect corporate managers and benefited financial institutions to offer to any change.
