Most failure prediction models developed over the past fifteen years have been based on firms' financial characteristics one year before they collapsed. This article reports the results of a study employing multiple discriminant analysis on a sample of fifty-three British companies which failed over the period 1960–1971. Models were developed on various financial ratios and an industry indicator for each of the five years, prior to failure, and the results in fact show that the model developed from data five years before failure performed at least as well as that derived one year prior to bankruptcy.  相似文献

Oil has been a major driving force behind foreign interests, regional and domestic balance of power, and territorial conflicts in the Persian Gulf. As a result of the ‘9/11’ terrorist attacks debates on oil and the United States' security agenda have significantly shifted. If on one side, those opposing US military interventionism have argued that the ‘war on terror’ provided one more convenient cover for a renewed ‘imperialist oil grab’ in this region; on the other, links between oil and terrorism pointed at problems of governance in oil-producing countries. As the ‘war on terror’ became justified as a ‘war of liberation’ against oil-funded dictators, the US portrayed its foreign policy as shifting from ensuring free access to oil for the world market, to ensuring that oil is delivering ‘freedom’ to local populations. Although engaging the crucial issue of oil governance, there is yet little evidence given the number of war victims and potential vested interests that a US policy shift from ‘free oil’ to ‘freedom oil’ is genuine and viable.  相似文献

The issue of accountants' role in decision-making has been the center of attention of lots of studies in the last decade but never did it get the adequate coverage in Lebanon. This paper studies to what extent accountants are involved in the managerial decision-making in Lebanon. Two hundred experienced accountants from all over the country were randomly selected for a questionnaire survey. This survey provides evidence as to what factors contribute to the variance of influence accountants have in managerial decision-making. The results from the questionnaires varied, but we conclude that accountants' involvement in new product development (NPD), the skills that accountants have, their role in the financial analysis of the firm, and how much the finn they work for encourages them to advice on business decisions affect the degree of contribution an accountant has to decision-making. The findings of this research could be used as a reference to help in understanding the role of accounting in Lebanon by various finns and organizations.  相似文献

The present paper addresses the problem of computing implied volatilities of options written on a domestic asset based on implied volatilities of options on the same asset expressed in a foreign currency and the exchange rate. It proposes an original method together with explicit formulae to compute the at-the-money implied volatility, the smile's skew, convexity, and term structure for short maturities. The method is completely free of any model specification or Markov assumption; it only assumes that jumps are not present. We also investigate how the method performs on the particular example of the currency triplet dollar, euro, yen. We find a very satisfactory agreement between our formulae and the market at one week and one month maturities.  相似文献

This article contributes to the literature on the convergence of financial systems in the euro area by estimating household credit demand in individual countries. Using the ARDL framework advocated notably by Pesaran et al. (1999 Pesaran, MH, Shin, Y and Smith, RP. 1999. Pooled mean group estimation of dynamic heterogeneous panels. Journal of the American Statistical Association, 94: 62134. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]), the article provides evidence on the convergence of long-run credit demand determinants (interest rates, investment and house prices) in the largest euro area countries, while short run-dynamics remain heterogenous across countries. The article also demonstrates that the equation uncovers demand rather than supply behaviour.  相似文献

This paper examines the relevance of institutional investors’ investment horizon, as reflected in the response of firm investment to internal cash flows. We argue that institutional investors with longer investment horizons have greater incentives and efficiencies to engage in effective monitoring. This improved monitoring mitigates asymmetric information and agency problems, and in turn reduces the wedge between the costs of internal and external funds. As a result, the sensitivity of firms’ investment outlays to internal cash flows decreases in the presence of institutional investors with long-term investment horizons. Using a sample of 8402 US firms over the period 1981–2008, we provide empirical evidence consistent with these arguments.  相似文献

The biophysical benefits of zero tillage (ZT) are well documented in the literature. However, the literature on its economic benefits, especially in the context of small and medium‐scale farmers in the temperate developing world is scanty. Using a study of 621 wheat farmers in Syria, we provide empirical evidence on the impacts of adoption of ZT on farm income and wheat consumption. We use propensity score matching (PSM) and endogenous switching regression (ESR) approaches to account for potential selection biases. After controlling for confounding factors, we find that adoption of the ZT technology leads to a US$ 189/ha (33%) increase in net crop income and a 26 kg (34%) gain in per capita wheat consumption per year (adult equivalent) – an indication of meaningful changes in the livelihoods of the farm households. Besides the biophysical and environmental benefits documented elsewhere, our results suggest that adoption of ZT can also be justified on economic and food security grounds. Therefore, ZT can have sizeable impacts in transforming the agricultural sector in the temperate developing world provided that the technology is well promoted and adopted.  相似文献

In this paper, a hybrid system combining neural networks and genetic training is designed to forecast future oil prices. The architectural design is that of the multilayer back propagation network that is fed monthly prices for West Texas Intermediate covering the period 1986–2014. The model’s predictions are compared to those of the one, two, three, and four-month futures prices and are evaluated both on their level of accuracy as well as correctness. While accuracy measures the degree of error, correctness tests the model’s ability to predict the direction of the movement. By processing information more efficiently, and identifying patterns that may be ill-defined as a result of pronounced price volatility, this paper aims to improve the accuracy of oil price forecasts.  相似文献
