Risk,return and mean‐variance efficiency of Islamic and non‐Islamic stocks: evidence from a unique Malaysian data set 下载免费PDF全文
We find that Islamic stocks are more mean–variance efficient than non‐Islamic stocks and the market because they reduce risk of the same level of returns. We combine a unique Malaysian data set of individual Islamic stocks (as opposed to aggregate stock indices) since 1997 with a new method where we apply Islamic business activity and financial ratio screens to the universe of Malaysian stocks. Both data sets show that Islamic stocks have an annualised standard deviation that is on average 3.43–3.78 percent points lower compared to non‐Islamic stocks. This lower variance of Islamic stocks is exclusively driven by financial ratio screens. 相似文献

This study empirically analyses the effect that the bankruptcy law has on firms’ performance based on its financial situation. To do this, we considered the different types of efficiency and their influence on firms’ value. The study was carried out for Germany, Spain, the United States, France and the United Kingdom. We applied System‐GMM estimation to dynamic panel data. The main results show that under creditor‐oriented systems, there is a decrease in the value of both financially distressed firms and those filing for bankruptcy. 相似文献

It has become increasingly popular to advise investors to relocate their funds from a primarily stock portfolio to a primarily bond portfolio as they get older. However, the well-known decision rules such as mean–variance or stochastic dominance rules are unable to explain this common practice. Almost stochastic dominance (ASD) and almost mean–variance (AMV) approaches are used to examine the dominance of stock and bond portfolios. ASD and AMV rules unambiguously support the popular practice of advising higher stock to bond ratio for long investment horizons. Hence, we provide an explanation to the practitioners’ recommendation within the expected utility paradigm. 相似文献

This paper reviews the research agenda lineage on public–private partnerships (PPPs) from Broadbent and Laughlin's seminal piece in 1999. The PPP phenomenon is viewed at five levels: project delivery, organisational form, policy, governance tool and as a phenomenon within a broader historical and cultural context. We argue that whilst a variety of research issues will continue to be relevant, five corresponding areas deserve future visibility for a renewed research agenda: (1) Financialisation of PPPs, (2) global PPP market actors, (3) internationalisation of policy on PPPs, (4) long‐term complex contracts as a governing regime and (5) PPPs in BRICS and developing countries. 相似文献

We study the autocorrelation and conditional volatility of the hourly Dow Jones Industrial Index return data from October 1974 to September 2002 using an exponential asymmetric AR–GARCH specification with a generalized error distribution. Our findings document a positive autocorrelation in hourly return data in the early years of the sampling period, but the autocorrelation turns negative after 1986 and the negative shock causes more impact on the conditional volatility. This latter period evidence stands in contrast to prior findings employing lower frequency and/or earlier year data. In addition, our results present some evidence of a negative relation between autocorrelation and conditional volatility before 1986 (albeit weaker than prior findings), but this negative relationship disappears after 1986. 相似文献

It has become standard practice in the fund performance evaluation literature to use the bootstrap approach to distinguish “skills” from “luck”, while its reliability has not been subject to rigorous statistical analysis. This paper reviews and critiques the bootstrap schemes used in the literature, and provides a simulation analysis of the validity and reliability of the bootstrap approach by applying it to evaluating the performance of hypothetical funds under various assumptions. We argue that this approach can be misleading, regardless of using alpha estimates or their t‐statistics. While alternative bootstrap schemes can result in improvements, they are not foolproof either. The case can be worse if the benchmark model is misspecified. It is therefore only with caution that we can use the bootstrap approach to evaluate the performance of funds and we offer some suggestions for improving it. 相似文献

This paper analyzes the determinants of returns generated by mature European private equity funds. It starts from the presumption that this asset class is characterized by illiquidity, stickiness, and segmentation. Given this presumption, Gompers and Lerner (2000) have shown that venture deal valuations are driven by overall fund inflows into the industry that yield the putative ‘money chasing deals’ phenomenon. It is the aim of this paper to show that this phenomenon explains a significant part of the variation in private equity funds' returns. This is especially true for venture funds, as they are affected more by illiquidity and segmentation than buy‐out funds. In the context of a WLS‐regression approach the paper reports a highly significant impact of total fund inflows on fund returns. It can also be shown that private equity funds' returns are driven by GP's skills as well as stand‐alone investment risk. In a bootstrapping context we can show that most of these results are quite stable. 相似文献

This case provides students the opportunity to apply strategic variance analysis (SVA) methodology in analyzing the performance changes realized in an airline merger. The U.S. Airways–America West merger provides an example of a complex, strategic action that simultaneously impacts firm size, unit pricing and costs, efficiency, and capacity for the combining airlines. This merger provides a rich example for the analysis since it combines U.S. Airways, a higher cost network airline that is geographically focused on the Eastern U.S., with America West, a low cost airline operating primarily along the Western U.S. The case includes merger and acquisition (M&A) theory discussing market power vs. efficiency motives for mergers and discusses the role of the U.S. Department of Justice and Federal Trade Commission in evaluating M&As and their impact on markets. The case asks students to serve as consultants applying the SVA methodology to the past U.S. Airways–America West merger and provide conclusions. 相似文献

We construct new measures of fund style, performance and activity from linear combinations of off‐the‐shelf stock‐market indices. A fund's benchmark portfolio is a linear combination of two or more reference portfolios that in a least‐squares sense most closely approximates the fund's portfolio. The resulting linear combination scalar is itself a measure of fund style and the distance between a fund and its benchmark is a measure of fund activity. Our approach has a number of advantages over existing characteristic‐matching methods. We illustrate our approach using a data set of US institutional funds. 相似文献

Using hand‐collected data, we creatively construct an ‘on‐balance‐sheet shadow banking business’ (OBS‐SBB) measure to precisely quantify commercial banks’ shadow banking activity concealed on their balance sheets. We show that OBS‐SBB activities could both increase individual and systemic risks. To further test the underlying mechanisms, we use China’s implementation of Basel III as an exogenous shock and employ the difference‐in‐differences approach. We find that banks demand OBS‐SBB in order to bypass capital requirements, previously less‐capitalised banks significantly increase their OBS‐SBB ex‐post, and greater impact is found among small and medium‐sized banks and during loose monetary policy periods. 相似文献

This paper constructs and tests alternative versions of the Fama–French and Carhart models for the UK market with the purpose of providing guidance for researchers interested in asset pricing and event studies. We conduct a comprehensive analysis of such models, forming risk factors using approaches advanced in the recent literature including value‐weighted factor components and various decompositions of the risk factors. We also test whether such factor models can at least explain the returns of large firms. We find that versions of the four‐factor model using decomposed and value‐weighted factor components are able to explain the cross‐section of returns in large firms or in portfolios without extreme momentum exposures. However, we do not find that risk factors are consistently and reliably priced. 相似文献

Assessing performance and value-creation capabilities in Lean healthcare: insights from a case study
ABSTRACTLean thinking is increasingly being applied worldwide. Yet its actual impact is still a puzzle, particularly when a ‘full-implementation approach’—which entails the adoption of a strategic approach to Lean dissemination on policy deployment procedures—is used. Focusing on the healthcare sector, this paper presents and tests a comprehensive measurement framework for Lean interventions. The paper explains how Lean testing can help decision-makers to solve managerial issues related to Lean initiatives. 相似文献

This study empirically examines the investment value of security analyst recommendations on constituent stocks of the S&P/ASX 50 index. We find that stocks with favourable (unfavourable) recommendations on average outperformed (underperformed) the benchmark index. An investment strategy using the Black–Litterman asset allocation model that incorporates consensus analyst recommendations, in conjunction with daily rebalancing, outperforms the market in terms of return and risk‐adjusted performance measures. The investment strategy involves high levels of trading, and no significant abnormal returns are achieved after transaction costs. Less frequent rebalancing, under most situations, causes a decrease in both performance and turnover. Filtering of dated recommendations causes an increase in turnover, while having mixed effects on investment returns. 相似文献

This paper argues that the commonly used market indices imply forms of active investment management in disguise. The selection and rebalancing rules make these indices highly exclusive and dynamic regarding their underlying components and significantly bias their performance. Any passive investment tracking these indices turns into an active strategy characterised by market timing and state‐dependent performance. Evidence is provided that exclusive indices outperform (underperform) more inclusive peer indices in upward (downward) markets. The constitution and maintenance rules of exclusive indices correspond to a set of active trading and investment rules similar to momentum strategies. 相似文献

This study analyzes how inflation affects innovation and international technology transfer via cash‐in‐advance constraints on R&D. We consider a North–South quality‐ladder model that features innovative Northern R&D and adaptive Southern R&D. We find that higher Southern inflation causes a permanent decrease in technology transfer, a permanent increase in the North–South wage gap, and a temporary decrease in the Northern innovation rate. Higher Northern inflation causes a temporary decrease in the Northern innovation rate, a permanent decrease in the North–South wage gap, and ambiguous effects on technology transfer. Finally, we calibrate the model to China–U.S. data to perform a quantitative analysis. 相似文献

This paper examines trade credit policies of small firms operating in a bank‐dominated environment (Finland). We find that creditworthiness and access to capital markets are important determinants of trade credit extended by sellers. The level of purchases is positively correlated with the level of accounts payable. Larger and older firms and firms with strong internal financing are less likely to use trade credit, whereas firms with a high ratio of current assets to total assets, and firms subject to loan restructurings use it more. Negative loan decisions by financial intermediaries increase and a close bank‐borrower relationship decreases the probability that a firm does not take advantage of trade credit discounts. 相似文献
