《企业会计准则》对会计政策变更和会计估计变更的范围做了原则上的划分,符合准则要求的变更在上市公司是允许的。但某些上市公司出于盈余管理的需要,可能利用会计政策变更或会计估计变更操纵利润,违反了国家的相关政策,误导了投资者。鉴于此,应从完善制度、外部监管和公司治理等多角度减少滥用会计政策变更和会计估计变更的现象。  相似文献

This paper provides strong evidence of time-varying return predictability of three precious metals from January 1987 to September 2014. We use three variations of the variance ratio test, the nonlinear Brock, Dechert and Schieinkman test as well as the Hurst exponent to evaluate the time-varying return predictability of precious metals to reduce the risk of spurious results. Our full sample results report mixed findings where some tests indicate significant predictability while some suggest no predictability. However through a time-varying procedure, we show that each precious metal market goes through periods of significant predictability as well as periods of unpredictability. Therefore this finding suggests that return predictability does vary over time and is not a static, all-or-nothing condition and therefore is consistent with the adaptive market hypothesis. We also show that platinum is the most predictable of the three precious metals and silver the least predictable, which may be of great to investors who include precious metals in their investment portfolios.  相似文献

Recent empirical research using real estate data has supported the weak and semi-strong forms of the efficient markets hypothesis. Previous studies have not included an estimate of expected appreciation into the tests of market efficiency, thus raising a question about the reliability of the results. We first use a market model to test for market efficiency with results similar to those reported by others. We next use a dynamic multiple indicator, multiple cause (DYMIMIC) model, which extracts a vector of expected appreciation from the price data, to test market efficiency. This approach produces superior results and a stronger conclusion about the efficiency of housing markets. The results indicate limited adjustment delays which can be explained by the existence of high transactions and search costs.  相似文献

This study evaluates the existence of the adaptive market hypothesis (AMH) as an evolutionary alternative to the efficient market hypothesis (EMH) by applying daily returns on the TEPIX index in the Tehran stock exchange (TSE) in Iran. The data span of daily returns is from 1999 to 2013. In this paper four different tests in the form of two distinguished classes (linear and nonlinear) have been used to study adaptive behavior of returns. The results that were obtained from linear (automatic variance ratio and automatic portmanteau) and nonlinear (generalized spectral and McLeod–Li) tests represent the oscillatory manner of returns about dependency and independency which corresponds with the adaptive market hypothesis.  相似文献

The main purpose of the study is to determine whether the equity markets of Brazil, Russia, India and China (BRIC) may be considered weak-form efficient in recent years. The major findings using daily data and a bias-free statistical technique with a sample spanning from September 1995 to March 2010 indicate that the results from the last sub-periods, including the subprime crisis, support the belief that these markets may have been approaching a state of being fairly weak-form efficient, which reflects the future prospects of BRIC countries.  相似文献

Excess Returns to R&D-Intensive Firms   总被引:1,自引:0,他引:1  
Recent studies indicate that both current R&D investment levels and current or recent changes in R&D investment are positively associated with subsequent excess (risk-adjusted) stock returns. The tentative explanation offered for these results is that shares of R&D-intensive firms are mispriced because investors fail to see through earnings distortions caused by conservative accounting for R&D costs. However, an alternative explanation is that conventional controls for risk do not completely capture the riskiness of R&D-intensive firms, causing measured excess returns for these firms to be biased upward. This study provides evidence useful for distinguishing between the mispricing and risk explanations for R&D-related excess returns. Overall, our empirical results suggest that the positive association between R&D investment levels and excess returns is more likely to result from failure to control adequately for risk than from mispricing. On the other hand, our results do not rule out the possibility of a second source of excess returns that are due to mispricing and that are associated with changes in the level of R&D investment.  相似文献

We discuss the implications of an alternative to the efficient market hypothesis (EMH) the adaptive market hypothesis (AMH). The AMH advances a theoretical basis for a new financial paradigm which can better model such phenomena as the recent financial crisis. The AMH regards the financial market order as evolving, tentative and defined by creative destruction in which trading strategies are introduced, mutate to survive, or face abandonment. The concept of investor rationality is less helpful than the distinction between investment strategies which are more or less well adapted to the prevailing market environment. We outline how a more systematic and grounded basis for behavioural finance can be developed in line with the latter approach. Based on this we develop testable hypotheses allowing the AMH to be distinguished from the EMH. Finally, we discuss how the AMH can aid our understanding of important issues in finance. A central insight is that in the survival of richest, as opposed to fittest, implied by the AMH there is much room for misallocation of resources as price and value uncouple. In this shifting financial market order the regulatory State features as a further market in which the vote market verifies or disrupts market conditions.  相似文献

Clinical directors and medical managers expected accounting information would assume high importance for institutional control as a consequence of NHS reforms. However, clinical directors were not comfortable with the symbolism of formal accounting controls. Their individual understanding of accounting information varied, but was modest overall. Medical managers were more inclined to accept and respond to financial controls. However, acceptance and response was frustrated for all users by inaccuracy and lateness of accounting reports. Cost savings were prompted more by established professional attitudes than in response to accounting reports. Non-financial controls remained the dominant mode of operational control.  相似文献

我国银行业市场结构与市场绩效的实证研究   总被引:5,自引:0,他引:5  
陈敬学 《金融论坛》2004,9(5):23-29
本文运用非参数的数据包络分析法计算我国银行业的X-效率和规模效率,在此基础上对市场结构与市场绩效间的关系进行了实证研究,结果表明在我国银行业市场中"结构-行为-绩效"假说和"有效结构"假说均不成立;作者还进一步从动态的角度,考察了我国银行业市场结构的变化对整体经营绩效的影响,发现"银行内效应"决定了我国银行业绩效变化的方向;但包括市场份额效应、交叉效应和进入效应在内的再配置效应也很重要,特别是行业绩效下降的时期,正的"再配置效应"改善了我国银行业经营的整体业绩,遏制了整体业绩的进一步下降.  相似文献

Are Housing Price Cycles Driven by Irrational Expectations?   总被引:3,自引:0,他引:3  
This paper investigates the extent to which condominium apartment prices are set in an efficient asset market. Unlike previous work that focuses on the time-series properties of measures of excess returns, the analysis is framed in terms of the changes in observable house prices over time. More precisely, the paper develops and applies a test of the joint null hypothesis of rational expectations, perfect markets, and no risk premium in the Vancouver condominium apartment market. The empirical results provide significant evidence against the joint null hypothesis. On average, ex post house price changes move in a direction opposite to their rational expectation. This approach offers a methodological advantage over the standard efficiency literature and is shown to provide a more powerful test of market efficiency than conventional return regressions. Another contribution of the paper is to characterize the time-series properties of deviations of condominium prices from those predicted by the risk-neutral rational expectations model, using cointegration and random coefficients techniques. Deviations in house price changes from their (risk-neutral) rational expectations are time varying, stationary, and related to the stage of the real estate price cycle.  相似文献

Dissanaike (1997) found a long-term winner-loser effect in the UK, within a sample of large (FT500) companies. However, he did not investigate as to whether there was a size effect within his sample, nor did he check to see if it subsumed his winner-loser effect. We find evidence of a size effect within the FT500 sample, and the size and winner-loser effects are not unrelated. But, there is no evidence to suggest that the size effect subsumes the winner-loser effect.  相似文献
