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.  相似文献

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.  相似文献

The conceptual model presented in this article argues that corporations exhibit specific behaviors that signal their true level of moral development. Accordingly, the authors identify five levels of moral development and discuss the dynamics that move corporations from one level to another. Examples of corporate behavior which are indicative of specific stages of moral development are offered.R. Eric Reidenbach is Professor of Marketing and Director of the Center for Business Development and Research at the University of Southern Mississippi. He has written extensively on business and marketing ethics.Donald P. Robin, Professor of Business Ethics and Professor of Marketing at the University of Southern Mississippi, is coauthor with R. Eric Reidenbach of two recent books on business ethics with Prentice-Hall. He is a frequent lecturer on business ethics and is the author of several articles on the subject.  相似文献

This study examines effects of four combinations of accounting bases and service levels — GAAP and income tax bases, and audit and review service levels — on loan officers' decisions, both separately and in interaction. It examines effects on loan decisions and perceptions of interest rates, default risk, confidence, and usefulness. The interaction of accounting basis and service level significantly affects perceived confidence but does not affect other decisions. Accounting basis and service level separately affect interest rates, default risk, and report usefulness, but do not affect the loan decision.  相似文献

In the last few years various legislative proposals have been made to impose a transaction or excise tax on securities and derivative market transactions. Although there have been considerable discussion and analysis of the wisdom of imposing such a tax on securities markets, there has been no analysis of the pros and cons of extending the tax to futures markets. This article attempts to fill this gap, first, by examining the various rationales advanced to support a tax on securities markets to determine their applicability to futures markets and, second, by analyzing the likely effects of the tax on the competitiveness and efficiency of futures markets. In addition, the revenue-raising potential of a tax on futures transactions is evaluated. I conclude that a tax on futures markets will not achieve any important social objective and will not generate much revenue.  相似文献

This paper studies federal auctions for wildcat leases on the Outer Continental Shelf from 1954 to 1970. These are leases where bidders privately acquire (at some cost) noisy, but equally informative, signals about the amount of oil and gas that may be present. We develop tests of rational and equilibrium bidding in a common values model that are implemented using data on bids and ex post values. We also use data on tract location and ex post values to test the comparative static prediction that bidders may bid less aggressively in common value auctions when they expect more competition. We find that bidders are aware of the "winner's curse" and their bidding is largely consistent with equilibrium.  相似文献

Single or double bounded contingent valuation? A Bayesian test   总被引:2,自引:0,他引:2  
This paper evaluates the performance of asymptotic approximations of the Bayes factor to appraise the relative likelihoods of the bivariate and the restricted double bounded models for contingent valuation. The performance of the Bayes factor test is studied by Monte Carlo simulation showing that it correctly chooses the bivariate model when appropriate, but tends to over predict the double bounded model when the correlation coefficient is not estimated accurately. However, the quadratic error in estimating willingness to pay is reduced if the model preferred by the test is chosen. In addition, we consider the effect of averaging the estimates of WTP from both models, weighting each model with its posterior probability. The results show that ‘model averaging’ across the competing hypothesis further reduces the squared error. The applications with two data sets on National Parks show that the test rejects the restricted double bounded hypotheses against the bivariate model.  相似文献

abstract Drawing on social constructionist theory this paper applies discourse analysis to ten narratives told by service delivery staff in one distribution network. The analysis looks at how the narratives construct the organization through their constructions of self (the narrator), customer and manufacturer and their constructions of the relationships linking these three sets of actors. The paper argues that the narrators construct the self either as an organizational customer or an organizational partner. The two constructions locate conflict either within the organization or at the customer–organizational boundary respectively. The implications of this are suggested. Contrasts between the manner in which organizational members construct the self as customer or partner and the construction of the organizational member in the internal customer literature are highlighted and briefly discussed.  相似文献

Comparing the global situation in the year 2000 with what the respondent samples from 10 countries predicted 30 years earlier, the conclusion can only be that people were remarkably accurate. This does not mean that any single respondent was that accurate but that anybody, who would have liked to anticipate the year 2000, would have done quite well based on these samples. Actually, the peripheries in the samples came out even better than the centers, making us wonder what education and high special position are actually about. One possible set of explanations would be that the peripheries know better where the shoes pinch, are more holistic and are not paid by anybody to make self-fulfilling or self-denying predictions.We are going to look at what people thought and what actually happened, in three movements. The first is about what they thought about the futures of their own societies and the second about international futures. The third movement deals with how their hopes and expectations depended on who they were, more specifically: whether they belonged to the center or the periphery in their countries.  相似文献
