This article aims to identify the factors influencing the use of creative accounting in the public sector. Its distinctive feature is that it sheds light on creative accounting when used, not to hide public deficits, but to conceal surpluses. It especially explores the impact of the finance minister’s (FM)’s background on the phenomenon. We take advantage of the quasi-experimental settings of the Swiss cantons in which the financial management act sets out the possibility of implementing certain accounting gimmicks, including mainly additional ‘depreciation’ charges. These charges, which are depreciations in name only, enable the FM to artificially inflate expenses, thus increasing the deficit or reducing the surplus. Our panel data set of the 26 cantons over the period 1980–2012 includes a new data set of creative accounting and of 116 cantonal FMs. Our results indicate that the FMs cook the books irrespective of their personal or ideological background with the exception that trained economists tend to apply creative accounting more. Additionally, stringent fiscal rules urge FMs towards more surplus-hiding accounting. 相似文献

We present the results of flight simulator experiments (60 runs) with randomly selected airline pilots under realistic operational conditions and discuss them in light of current fuel regulations and potential fuel starvation. The experiments were conducted to assess flight crew performance in handling complex technical malfunctions including decision-making in fourth-generation jet aircraft. Our analysis shows that the current fuel requirements of the European Aviation Safety Agency (EASA) are not sufficient to guarantee the safety target of the Advisory Council for Aviation Research and Innovation in Europe (ACARE), which is less than one accident in 10 million flights. To comply with this safety target, we recommend increasing the Final Reserve Fuel from 30 min to 45 min for jet aircraft. The minimum dispatched fuel upon landing should be at least 1 h. 相似文献

Structural equation modelling (SEM) is an estimation method that can handle a large number of exogenous and endogenous factors as well as unobserved (latent) variables that are specified as linear combinations of observed (measurement) factors. This paper presents a SEM procedure with latent variables for estimating the financial and non-financial performance in airline companies. The model includes independent, mediator and dependent latent variables. The sample for this research comprises 214 airline companies. The results indicate that the model is capable of estimating performance with respect to the economic situation and it has also been determined that two types of constructs affect performance. One type is the economic situation acting as an initial construct and the other is the internal operation acting as the mediator in the research model. 相似文献

The power motive, defined as the desire to impact the behavior and emotions of another person, has long been controversial. On one side, the exercise of power has been put forth as a fundamental human need greater in strength than the need to survive. On the other, it has been vilified for its potentially devastating consequences. We argue the latter view is distorted, and, by relying too heavily on it, we have come to misunderstand the essential nature of power and its use by leaders charged with driving performance. It is not the power motive that leads to corruption and tyranny, but rather how the power motive is channeled into behavior by other personality factors. Consequently, those charged with leader selection should place greater emphasis on how individuals with strong power motives differ in how they channel power. Doing so will support the selection of executives best equipped to deliver organizational performance. 相似文献

This study focused on identifying strategic criteria involved in selecting suppliers of restaurant products/services specific to casual dining, full service independent restaurants to obtain operational and strategic benefits for those managers operating in this highly competitive marketplace. A total of 765 responses were obtained from managers at independently owned restaurants throughout the U.S. Results revealed that ‘product’ and ‘financial/technical’ criteria had significant and positive effects upon operational benefits, while ‘product’ and ‘service’ had positive effects upon strategic benefits. When the sample was segmented into low and high supplier partnership groups, the positive effects of ‘financial/technical’ and ‘cost/price’ were significantly greater for the ‘high’ partnership group pertaining to operational benefits. ‘Product’ and ‘service’ and their effects upon strategic benefits were greatest for the high partnership group. Based on our findings, implications, limitations, and recommendations for future studies have been provided. 相似文献

High‐performance work systems and workplace performance in small,medium‐sized and large firms 下载免费PDF全文

This article draws on the Organisational Growth and Development (OGD) life cycle model to explore the relationship between high‐performance work systems (HPWS) and performance in firms of different size, thereby extending understanding of congruence or ‘best fit’ theory within strategic HRM debates. With reference to management control theory, economies of scale and the availability of specialist managerial skills, the article hypothesises that while an HPWS–performance relationship might exist in small, medium‐sized and large firms, the relationship will be stronger in large firms than in both small and medium‐sized firms, and stronger in medium‐sized firms than in small firms. Analysis of data from the British Workplace Employment Relations Survey demonstrates, however, that there is no association between HPWS and workplace performance in medium‐sized firms, in contrast to the positive relationship between HPWS and performance found in large firms and between HPWS and labour productivity in small firms. 相似文献

Corporate lobbying activities are designed to influence legislators, regulators and courts, presumably to encourage favorable policies and/or outcomes. In dollar terms, corporate lobbying expenditures are typically one or even two orders of magnitude larger than spending by Political Action Committees (PAC), and, unlike PAC donations, lobbying amounts are direct corporate expenditures. We use data made available by the Lobbying Disclosure Act of 1995 to examine this more pervasive form of corporate political activity. We find that, on average, lobbying is positively related to accounting and market measures of financial performance. These results are robust across a number of empirical specifications. We also report market performance evidence using a portfolio approach. We find that portfolios of firms with the highest lobbying intensities significantly outperform their benchmarks in the three years following portfolio formation. 相似文献

The paper presents an integrated viewpoint of technological innovation strategy by considering both the firm and industry levels. Further, we provide a new open innovation framework by adopting a knowledge flow perspective using patent citation information. Finally, we consider a firm’s outbound open innovation performance using cites per patent information together with financial performance to look at both the practical and the potential effects of technological innovation strategy. Through these analyses, this study examines determinants of open technology innovation activity in the information and communication technology manufacturing industry in Korea and draws managerial and policy implications for effective industry promotion and improvement of technology innovation capability. 相似文献

重叠滤波多音(O-FMT)是针对滤波多音(FMT)系统频谱利用率低的缺点而根据超奈奎斯特(FTN)概念引入子载波重叠得到的方案。鉴于O-FMT系统在频偏环境下的性能缺陷,理论分析了频偏对系统信号各部分的影响,比较了O-FMT与正交频分复用(OFDM)系统的抗频偏性能。针对频偏性能优化问题,提出了基于最佳线性无偏估计(BLUE)的改进盲估计算法,设计了基于频域滤波器系数的内嵌结构进行频偏补偿。仿真实验表明,O-FMT相比OFDM具有更好的抗频偏能力,改进的盲估计算法估计值精度更高,抗干扰、抗衰落能力更强,设计的频偏补偿结构可以使系统获得更好的性能。 相似文献
