Permanent magnets: a technological analysis

Abstract
Technology analysis is a new technomanagerial discipline that provides common frameworks for analysing individual technologies and their relationships to each other. It is used here to probe the development of a particular technology, namely that of permanent magnets.
The paper traces the development of permanent magnets over the past decade and explores possible future improvements in performance parameters. The strength of magnets (i.e. energy product as expressed in kilo Joules per cubic metre) has increased from approximately 40 in the 1930s to approximately 400 at present.
Future developments will be constrained by a barrier which seems to exist at approximately 525 kilo Joules per cubic metre. However this is viewed as a barrier that can be transcended and not as an immutable limit. It therefore signifies a possible breakthrough zone.
S-curve theory leads analysts to speculate about a possible breakthrough during the five year period leading up to 1995. At that date magnetic strengths of 600+ kilo Joules per cubic metre could be aimed for.
Increased magnetic strength will improve the performance parameters of all technologies utilising magnets, unleash new magnetic based technologies and threaten many traditional areas in the fields of matter processing, transporting and storing, energy processing, and information processing and storing.
These effects will cascade through the entire technological landscape creating new markets and destroying others. The article gives an overview of these impacts on the technological landscape.     

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.     

Evidence on the existence of speculative bubbles in farmland prices

We conduct tests for the contribution of speculative bubbles to farmland prices. These tests are carried out under the hypothesis that farmland investors rationally form expectations. The outcome of tests reported here allows us to infer whether farmland prices are determined by market fundamentals-discounted returns from the highest economic land use-or whether rumors about farmland price movements are self-fulfilling. The tests are stationarity and cointegration tests relating farmland prices to rents. The tests are carried out using data from three farm production regions-the Corn Belt, the Northern Plains, and the Lake States. In each region, we find little evidence to reject the hypothesis that market fundamentals determine farmland prices.     

Regulatory Monitoring and the Impact of Bank Holding Company Dividend Changes on Equity Returns

This paper examines the impact of announcements of dividend changes by bank holding companies (BHCs) on equity returns. Many empirical studies of dividend behavior reveal positive market responses to dividend increases, which have been interpreted as confirmation of the signalling theory of dividend behavior. These studies typically focus on “large” changes, however. We argue that BHCs allow for a stronger test of signalling theory because regulatory monitors, in effect, “certify” dividend signals. Consequently, even “small” dividend increases should result in positive abnormal equity returns. Using the event study methodology, our results generally confirm this hypothesis for a sample covering the period 1973–1987.     

PRINCIPAL AND AGENCY TRADES BY STOCKBROKERS ARE COMPLEMENTARY: THE WELFARE EFFECTS OF DEREGULATING AGENCY TRADING AND BANNING PRINCIPAL TRADES

This paper models the demand for stockbrokers' services in Australia, consisting of two related services, agency trades and principal trades. The relationship between agency and principal trades is estimated. The results indicate that the two services are complements rather than substitutes. Using unique accounting information, a model of agency and principal trading activities is estimated to determine the welfare effects of (i) deregulating brokerage commissions and (ii) a ban on principal trading by brokers. The results show a sizeable welfare gain to investors (amounting to about 60% of the gross revenue of brokers) stemming from deregulation of the minimum charge for agency trades. The loss in profitability by brokers due to deregulation is also computed and shown to be negligible. The results also show that due to complementarity, a ban on principal trading, even with deregulation of agency trading, can impose an arbitrarily high cost on investors which could, in principle, offset the gains from agency deregulation.     

A model of translation of foreign financial statements under inflation in the United States and Canada*

Abstract. This study investigates the translation of foreign financial statements in inflationary economies. The analysis is conducted by comparing the results obtained from the temporal and current rate methods to the translated adjusted-for-inflation (TAI) financial statements under varying degrees of purchasing power parity. The findings indicate that under perfect purchasing power parity, the temporal method yields undistorted results versus TAI. The current rate method, however, results in a distortion. When the purchasing power parity degree is not perfect, both the current rate and temporal methods distort the results. However, if the inflation exceeds the devaluation of the local currency, translation using the temporal method results in a lower distortion. This result is reversed when the devaluation of the local currency exceeds the rate of inflation. The study then proceeds to examine, from the viewpoint of a standard-setting body, the translation models in a cost-benefit framework. The results indicate that TAI is usually the best. This result is due to the fact that the benchmark model is more informative than the other methods, and the information production costs are close to the costs under the temporal method. Further, if the rate of inflation exceeds the devaluation of the local currency, the temporal method dominates the current rate method. The opposite holds if the devaluation of the local currency exceeds the rate of inflation. Moreover, this study examines the implications of CICA Handbook. Section 1650. The findings indicate that the Canadian variant of the temporal methods results in a distortion even when the purchasing power parity assumption holds. Résumé. L'auteur s'intéresse à la conversion des états financiers dressés en devises, dans les économies inflationnistes. Son analyse repose sur la comparaison des résultats de l'application de la méthode temporelle et de la méthode du taux courant à la conversion des états financiers ajustés pour tenir compte de l'inflation, selon divers degrés de parité du pouvoir d'achat. Suivant les résultats obtenus en situation de parité parfaite du pouvoir d'achat, la conversion à l'aide de la méthode temporelle est sans biais par rapport à celle de la conversion des états financiers ajustés pour tenir compte de l'inflation. La méthode du taux courant donne lieu, quant à elle, à un biais. Lorsque la parité du pouvoir d'achat n'est pas parfaite, la méthode du taux courant et la méthode temporelle faussent toutes deux les résultats. Toutefois, si l'inflation excède la dévaluation de la monnaie nationale, la conversion à l'aide de la méthode temporelle donne un biais moins accentué, relation qui s'inverse lorsque la dévaluation de la monnaie nationale excède le taux d'inflation. L'auteur procède ensuite, du point de vue d'un organisme de normalisation, à l'analyse des modèles de conversion sous l'angle coûts-avantages. Les résultats indiquent que la conversion des états financiers ajustés pour tenir compte de l'inflation est habituellement la meilleure. Cette constatation découle du fait que le modèle étalon est plus informatif que les autres méthodes, et que les coûts de production de l'information se rapprochent des coûts associés à la méthode temporelle. En outre, si le taux d'inflation excède la dévaluation de la monnaie nationale, la méthode temporelle l'emporte sur celle du taux courant. L'opposé est vrai si la dévaluation de la monnaie nationale excède le taux d'inflation. Enfin, l'auteur analyse les conséquences du chapitre 1650 du Manuel de l'I.C.C.A. et en vient à la conclusion que la variante canadienne de la méthode temporelle donne lieu à un biais, même quand l'hypothèse de la parité du pouvoir d'achat est respectée.     

Innovative productivity and returns to scale in the pharmaceutical industry

This study shows that firms in the pharmaceutical industry experience decreasing returns to scale in R & D as the level of R & D expenditures rises. The paper presents the results of our study of the innovative output of 16 pharmaceutical firms over a 19 year period. Given the strong correlation between R & D budgets and firm size, our study suggests the wave of mergers in the industry may yield less innovative productivity than managers expect.
