State-Space Estimation of Rational Bubbles in the Yen/Deutsche Mark Exchange Rate. — This paper considers a series that uncovered interest parity predicts to be white noise and inspects it for evidence of stochastic rational bubbles. State-space methods are used that specify a bubble component of the series as an unobserved state. The technique’s effectiveness is demonstrated by Monte Carlo experiments. One span of the series is found in which a stochastic rational bubble specification clearly dominates the white noise specification. It coincides with a period of general financial turm-oil in the associated economies, i.e. Japan and Germany during 1989 and early 1990. 相似文献

This paper illustrates the application of artificial neural networks (ANNs) to test the ability of selected SAS No. 53 red flags to predict the targets of the SEC investigations. Investors and auditors desire to predict SEC targets because substantial losses in equity value are associated with SEC investigations. The ANN models classify the membership in target (investigated) versus control (non-investigated) firms with an average accuracy of 81%. One reason for the relative success of the ANN models is that ANNs have the ability to ‘learn’ what is important. The participants in financial reporting frauds have incentives to appear prosperous as evidenced by high profitability. In contrast to conventional statistical models with static assumptions, the ANNs use adaptive learning processes to determine what is important in predicting targets. Thus, the ANN approach is less likely to be affected by accounting manipulations. Our ANN models are biased against achieving predictive success because we use only publicly available information. The results confirm the value of red flags, i.e. financial ratios available from trial balance in conjunction with non-financial red flags such as the turnover of CEO, CFO and auditors do have predictive value. © 2000 John Wiley & Sons, Ltd. 相似文献

A modern adaptation of the Ricardian model is used, which incorporates monopolistic competition and multiple factors to derive a MacDougall-type relation between a country's international competitiveness at the industry level and its productivity performance. This relation is implemented empirically for Canada and the United States, using panel data for twenty-five years and forty industries. A key finding is that the Canadian-U.S. productivity ratio is an important determinant of relative shares of Canadian firms in both Canadian and U.S. markets. Trade liberalization between Canada and the United States also plays a significant role in influencing market shares. JEL Classification: F11, F12
Niveau de productivité et compétitivité internationale : un autre coup d'œil à un vieux test . Ce mémoire utilise une adaptation moderne du modèle ricardien qui postule concurrence monopolistique et plusieurs facteurs pour dériver une relation à la MacDougall entre la compétitivité internationale d'un pays au niveau de l'industrie et son niveau de productivité. On calibre cette relation pour le Canada et les États-Unis en utilisant des données pour quarantes industries sur une période de vingt-cinq ans. Un résultat important est que le ratio de la productivité entre le Canada et les États-Unis est un déterminant important des parts de marché des firmes canadiennes tant au Canada qu'aux États-Unis. La libéralisation du commerce entre les deux pays joue aussi un rôle important dans la définition de ces parts de marché. 相似文献

The paper obtains new results about absolute and comparative advantage, by introducing international technological differences into the three–sector Findlay–Komiya and two–sector Oniki–Uzawa–Stiglitz models of open–economy growth with optimal saving. For example, if a country has the same Hicks–neutral advantage in all industries, it exports the capital–intensive tradable, even though the technological advantage is only absolute rather than comparative. Alternatively, even a small comparative advantage in some good is sufficient for the advanced country to export this product, regardless of relative factor supplies. In either case, the fundamental reason for trade is technological superiority rather than factor abundance. 相似文献

An efficiency‐wage model of steady‐state equilibrium with labor‐augmenting technical progress is developed to explore the long‐run relationship between unemployment and growth. The rate of productivity growth is either specified exogenously or determined endogenously. In both cases, we preserve key results of the Shapiro–Stiglitz efficiency‐wage analysis without growth. Our model, however, also yields some striking new results. For instance, an exogenous increase in the growth rate may raise the rate of efficiency‐wage unemployment, and a once‐for‐all rise in the labor force may reduce the unemployment rate in the endogenous‐growth case. 相似文献

The paper examines the transmission of inflation in Canada during 1962–1980 using an empirical methodology which is very flexible in determining the direction of casuality and the shape of distributed lag effects. The paper finds that US monetary growth exerted an important effect on Canadian inflation during both fixed and flexible exchange-rate periods. The evidence also shows that Canadian monetary growth has remained linked to US monetary growth under the present flexible exchange-rate regime. 相似文献

This paper conducts the first empirical assessment of the theories concerning the influence of ownership structure on bank risk-taking in the presence of regulations in Pakistan. The sample used in this paper comprises a panel data of 26 banks in Pakistan, for the period from 2000 to 2014. The analysis provides evidence that increase in ownership concentration leads to an increase in bank risk-taking. Managerial ownership is associated with high risk-taking at low and high levels of managerial ownership while at intermediate level, managerial ownership has negative impact on bank risk-taking. Different types of ownership of banks in Pakistan have different impact on risk-taking. While government, family and institutional ownership have a positive impact on bank risk-taking, foreign ownership has a negative impact on bank risk-taking. Furthermore, the results show that capital regulations are important in influencing bank risk-taking with regard to higher ownership concentration. The findings of this paper suggest that the relation between bank risk-taking and capital regulations typically depends on the type of ownership. 相似文献

The aim of this paper is to propose a comprehensive framework for simultaneously measuring the performance of sustainable service and manufacturing supply chain management. Application of the proposed approach also results in reduced uncertainty of the performance measurement process caused by qualitative criteria evaluation. The proposed approach consists of two main steps. First, the fuzzy decision‐making trial and evaluation laboratory (DEMATEL) method has been used to determine important criteria by avoiding low influences; and then a Mamdani fuzzy inference system model has been adopted and applied for performance evaluation of sustainable supply chain management (SSCM). This model is employed in order to cope with the vagueness that exists in the SSCM performance investigation due to the vagueness intrinsic in the evaluation of criteria. In the proposed model, human reasoning has been modelled with fuzzy inference rules and has been set in the system, which is an advantage compared with those models in which fuzzy set theory and multicriteria decision‐making models are integrated. The proposed approach has been implemented in the pipe and fitting industry in order to highlight its application in real life. Sensitivity analysis has been carried out to determine the influence of service and manufacturing criteria on SSCM performance. The findings reveal that sustainable manufacturing criteria compared with sustainable service criteria have more effect on the performance of SSCM. 相似文献
