Corporate Leverage and Nondebt Tax Shields: Evidence on Crowding-Out

A negative relationship between corporate leverage and tax shields has been predicted because a large nondebt tax shield reduces the expected value of interest tax savings and lessens the advantage of debt financing. Previous studies, however, have provided inconclusive and contradictory evidence on whether nondebt tax shields crowd-out debt financing. The analysis herein relies on unique constructs of discounted depreciation tax shields and presents evidence that crowding-out does not occur. Furthermore, it is shown that contradictory inferences may result from analysis of annual tax depreciation deductions instead of discounted tax shields. The findings suggest that firms with substantial cash flow from depreciation exploit their higher debt capacity by maintaining a capital structure with significantly more debt than otherwise.     

Organisation vs. culture: Japanese automotive transplants in the US

It has long been argued that the Japanese production organization is culture-bound and therefore not transferable to other countries. This article examines seven major Japanese automobile assembly plants and over 270 Japanese automotive parts suppliers in the US. The successful transfer of Japanese work and production organization in these ‘transplants’ suggests that Japanese production practices are organizational forms which can be uncoupled from Japanese culture and transferred to other countries.     

A longitudinal study of the cause and consequences of changes in diversification in the U.S. pharmaceutical industry 1977–1986

The paper hypothesizes that diversification by firms based in the pharmaceutical industry during the 1977-86 time period was primarily undertaken to reduce the risks associated with being dependent upon a technologically dynamic environment. Consistent with this non-efficiency motive for diversification, declining economic performance is predicted. A longitudinal empirical analysis provides support for these propositions.     

Distinctive characteristics of entities with an internal audit department and the association of the quality of such departments with errors*

Abstract. This research identifies those characteristics that could potentially influence a choice to create an internal audit department and tests via discriminant analysis to evaluate whether such attributes significantly distinguish between companies with and without an internal audit department. In addition, qualitative characteristics of such departments are described, as is the association of such traits with errors and the overall control environment. A sample of 260 companies is examined. Companies with internal audit departments are observed to be significantly larger, more highly regulated, more competitive, more profitable, more liquid, more conservative in accounting policies, more competent in their management and accounting personnel, and subject to better management controls. Key discriminant variables are the degree of regulation, decentralization, size, the duration of association with present auditors, the existence of an audit committee, EDP control, and pressures by external parties on management to achieve budgetary goals. Qualitative attributes of internal audit are systematically associated with the overall quality of the control environment, as well as errors. The most important attribute appears to be the independence of internal audit in terms of the propriety of the reporting level. An advantage of internal auditing is that external auditors report a 10 percent reduction in the number of hours incurred and greater flexibility appears to exist in the proportion of work performed in off-peak periods. Résumé. Les auteurs dressent l'inventaire des caractéristiques susceptibles d'influer sur le choix de créer un service de vérification interne et soumettent ces attributs à des tests, par voie d'analyse discriminante, afin de déterminer s'ils permettent d'établir une distinction claire entre les entreprises ayant et n'ayant pas de service de vérification interne. De plus, ils décrivent les caractéristiques qualitatives de ces services, de même que l'association de ces carctéristiques aux erreurs et au contexte global du contrôle. Les auteurs procèdent à l'examen d'un échantillon de 260 entreprises. L'étude révèle que les entreprises possédant des services de vérification interne sont beaucoup plus souvent des entreprises de grande taille, faisant l'objet d'une réglementation plus rigoureuse, plus concurrentielles, plus rentables, ayant davantage de liquidités, plus prudentes dans leurs conventions compatables, possédant une équipe de gestion et un personnel comptable plus compétents et soumises à de meilleurs contrôles de gestion. Les principales variables discriminantes sont le degré de réglementation, la décentralisation, la taille, la durée de l'association avec les vérificateurs actuels, l'existence d'un comité de vérification, le contrôle dans un cadre informatique et les pressions exercées par les tiers sur la direction pour l'atteinte des objectifs budgétaires. Les attributs qualitatifs de la vérification interne sont systématiquement asociés à la qualité globale du cadre de contrôle, de même qu'aux erreurs. L'attribut le plus important semble être le degré d'autonomie du service de vérification interne, c'est-à-dire le caractère approprié de ses liens hiérarchiques. La vérification interne comporte un avantage: les vérificateurs externes font état d'une réduction de 10 pour cent dans le nombre d'heures consacrées à la vérification, et il semble exister une plus grande souplesse dans la proportion du travail de vérification effectué en dehors des périodes de pointe.     

Daylight saving effect

Kamstra et al. [Kamstra, M.J., Kramer, L.A., Levi, M.D., 2000. Losing sleep at the market: the daylight saving anomaly. The American Economic Review 90, 1005–1011] argue that the mean weekend return following the changes in daylight saving time is less than the mean weekend return throughout the rest of the year. Opposing studies, such as Pinegar [Pinegar, J.M., 2002. Losing sleep at the market: comment. The American Economic Review 92, 1251–1256), reason that the observed results depend upon methodology. We extend the ongoing discussions by providing further evidence for equity markets and bond markets in Germany and across Europe. We further demonstrate that the daylight saving effect does not serve as a potential rationale for the weekend effect.     

Towards a complete real-time electricity market design

The general design for the real-time electricity market presented in this paper optimizes and prices both real and reactive power simultaneously in an AC setting, where all assets—generation, load and transmission—are allowed to bid and are financially settled at the locational price times energy consumed or produced. The result is that transmission lines are compensated for both capacity and admittance, providing incentives for efficient operation of transmission-related assets such as FACTS devices, if price-taking behavior is assumed. Losses are incorporated into the design and become an operating cost for transmission. The market design is shown to be revenue neutral and, under some assumptions, nonconfiscatory.
