CAPM option pricing

This paper extends the option pricing equations of [Black and Scholes, 1973] , [Jarrow and Madan, 1997] and [Husmann and Stephan, 2007] . In particular, we show that the length of the individual planning horizon is a determinant of an option’s value. The derived pricing equations can be presented in terms of the Black and Scholes [1973. Journal of Political Economy 81, 637–654] option values which ensures an easy application in practice.     

Another look at the role of the industrial structure of markets for international diversification strategies

This paper re-examines the extent to which gains from international diversification are due to differences in industrial structure across countries. Recent papers by Roll (1992), Journal of Finance 47, 3–42 and Heston and Rouwenhorst (1994), Journal of Financial Economics 36, 3–27 investigate this issue and find conflicting evidence. Using a new database, the Dow Jones World Stock Index, with coverage in 25 countries and over 66 industry classifications, we decompose comprehensively both country and industrial sources of variation. We confirm that little of the variation in country index returns can be explained by their industrial composition. We also uncover differences in the proportion of variation in industry index returns that is captured by country and industry factors and discuss the implications for global diversification strategies.     

Large-scale participatory co-shaping of technological developments: First experiments with PARDIZIPP

A future-oriented participatory procedure on the basis of the Delphi method was developed and empirically tested a first time with the goal to improve the shaping of technological developments. The technology under study here was micro-electronics or rather their relationship with labor and the test took place in NorthRhine–Westphalia.Today problems exist in all walks of life. There is a lot of talk about today's problems as if they were new, though one has heard similar arguments throughout history. How do we assess if we are really in danger of bringing the world to an end? Although this danger appears real, it would not be the first time in history that people have thought and felt like this—However, one thing that is new are the consequences of modern sciences and technology, which are not suited to given social and environmental requirements. They have given rise to questions concerning the quality of the decision-makers. The questioning of many of these decisions has increased for some time and is now getting more and more specific, with a demand for quality and information rather than managerial skills and competitiveness from the decision-makers. The term `decision-maker' describes those who determine the application of technology, science and technical equipment which has either existed for a long time already or has recently been developed.—It is not easy to change the structures and processes of decision-making so that new structures and processes will be more suited to social and environmental requirements. We have tested our ideas as to how this could be done, in an empirical project. Although we called it `Project NRW–2000', it would probably be better described as an experiment.²—We persuaded 90 ordinary people to participate in this project as `experts on daily life and work'. This group was asked to work in six regional sub-groups and discuss, with reference to three given normative societal scenarios for the year 2020, the relationship between microelectronics and labour markets of the year 2020, on the basis of a participatory Delphi procedure. Before we elaborate on the concept of our project in Section 3, we would like to outline it in terms of the mainstream of the sociology of technology as well as with research on `acceptance' in Section 1. In Section 2we will briefly illustrate the framework of the research programme `Socially Oriented Shaping of Technology' of the state of Northrhine–Westphalia, which funded our research project. Section 4particularly deals with the participatory elements of our project, while Section 5is devoted to the development of the scenarios. Section 6sums up the results of the `scenario-construction'. Regarding specific elements, we restrict ourselves to topics concerning technology, labour, and the relationship between women workers/employees and technology. As a final outlook we deal with the political implications of our approach. All that is left is to remind our readers that we regard this project as a first application or experiment within our overall approach.     

职工薪酬与会计稳健性——基于中国上市公司的经验证据

企业职工对未来可持续的高工资和管理层对未来低劳动力成本的不同期望,可能导致两者对会计稳健性需求的差异。本文以Khan et al.(2009)的C Score为会计稳健性的计量方式,分析了职工薪酬、工资刚性与会计稳健性的关系。结果显示:较高的职工薪酬与较强的会计稳健性相联系;工资的向下刚性特征与较强的会计稳健性相联系;作为工会规模代理变量的职工人数也与会计稳健性显著正相关。此外2008年实行《新劳动合同法》之后,企业的会计稳健性有了显著提高,这也可能侧面体现了职工与会计稳健性的关系。本文的研究意义在于联结了传统的职工薪酬研究和会计稳健性研究,对Watts(2003)提出的与会计稳健性相关的契约集合进行了扩展,显示了职工薪酬契约对会计稳健性的影响。     

Corporate tax payments under formulary apportionment: Evidence from the financial reports of 50 major U.S. multinational firms

Under a formulary apportionment system of taxing multinational corporate income, U.S. tax liabilities would be based on the product of a multinational firm's worldwide income and the fraction of their real activities that occur in the United States – typically, an average of asset, payroll, and sales shares. This analysis utilizes financial reporting data for 50 large U.S. multinational firms to analyze how tax payments would change under a possible formulary system, updating Shackelford and Slemrod (1998). Our time period is 2005–2007 instead of 1989–1993. We find that tax payments under formulary apportionment would increase modestly overall but by a lower magnitude than found by Shackelford and Slemrod. Given the changes in the international tax environment since the earlier time period, this is a puzzling finding; we speculate regarding possible explanations.     

Accountability and human rights: A tentative exploration and a commentary

There continues to be many attempts to articulate what is meant by Human Rights but Griseri and Sepella's (2010, p. 176) adaptation of Leighton et al. (2002) as “entitlements that one holds by virtue of being a human being” takes us to the heart of the matter. What is it to be human and what does humanity demand of us? But the notion is far from settled; it is far from uncontentious; despite its domination by lawyers it is far from simply legalistic; and the matter has only relatively recently been taken up as a matter of focus amongst business and management academics. Human rights have, as yet, almost no presence in accounting and finance. This short essay seeks to provide an introduction to the practitioner papers presented in this issue of CPA and in doing so to provide some context within which the papers might be better appreciated. As happens too often for comfort, practice (at least regulatory and NGO practice) is still leading research and theory in the field of Human Rights. Providing that context offers us the opportunity to speculate on how – notwithstanding the potentially seminal papers that also appear in this issue – we might see accounting academe recognising and responding more widely to Human Rights.     

Does auditor tenure affect accounting conservatism? Further evidence

Accounting regulators are concerned about the potential threat of long-term auditor–client relationships on auditor independence, leading to lower audit quality. Jenkins and Velury (2008, hereafter JV) document a positive association between the conservatism in reported earnings and the length of the auditor–client relationship. A primary objective of this study is to extend JV by providing evidence that the relationship between conservatism and auditor tenure is not unique for all firms. In particular, this study finds that the positive association only exists for large firms or firms strongly monitored by their auditors, while for smaller firms or firms weakly monitored by their auditors, I observe a significantly negative association between auditor tenure and conservatism.     

Announcement effects of convertible bond loans and warrant-bond loans: An empirical analysis for the Dutch market

This study investigates the announcement effects of offerings of convertible bond loans and warrant-bond loans using data for the Dutch market. The event study analysis shows that announcement effects of convertible bonds are associated with positive but insignificant abnormal returns and that announcements of warrant-bonds are associated with significant positive abnormal returns. These findings are similar to the results for Japanese hybrid debt, as reported by Kang et al. (1995) (Kang, J.K., Kim, Y.C., Park, K.J., Stulz, R.M., 1995. Journal of Financial and Quantitative Analysis, pp. 257–270) and Kang and Stulz (1996) (Kang, J.K., Stulz, R.M., 1996. Review of Financial Studies, pp. 109–139), but they contrast with studies for the United States that generally find significant negative abnormal returns for convertible bond loans and insignificant negative abnormal returns for warrant-bond loans. Our results cannot be attributed to differences in the corporate governance structures of the Netherlands and the United States. We find that the positive abnormal returns for the warrant-bond loans are caused by the packaging of the announcements with other (good) firm-specific news.     

The interdependencies of intra- and inter-organisational controls and work practices—The case of domestic care of the elderly

The paper gives a grounded account of inter-organisational controls and work practices in the public sector to complement previous literature's strong focus on inter-organisational customer–supplier relationships in the private sector. We draw theoretically on Hopwood's (1974) administrative, social and self controls, which enable us to analyse the influence of non-managerial controls on behaviour. Empirically, a case study of inter-organisational cooperation between home help units and health centres is used as the basis of analysis. Most inter-organisational controls were developed locally and involved a mix of administrative, social and self controls. Intra- and inter-organisational social and self controls were important forms of control which impacted on intra- and inter-organisational work practices and we see the need for a broad conceptualisation of control (Van der Meer-Kooistra and Scapens, 2008). Inter-organisational social controls created an informal hierarchy that by-passed the formal hierarchies of the two organisations. Self controls reinforced the importance of being flexible to accommodate pensioner's wishes and needs in specific care situations. We also show the importance of the internal financial situation of home help units for the analysis of the interdependencies of intra- and inter-organisational controls and work practices.     

Nonlinear trends in real exchange rates: A panel unit root test approach

We analyze the possibility of nonlinear trend stationarity as the alternative to unit roots in 23 OECD real exchange rates, 1974–1998, by adding nonlinear time terms to the CIPS panel unit root test of Pesaran (2007). We follow a thorough bootstrapping approach and propose a technique to adjust statistical significance for the use of multiple tests over several time trend orders. The unit root null that all real exchange rates have unit roots is rejected at better than the 0.05 level. Bootstrapped results from a procedure of Chortareas and Kapetanios (2009) suggest that the hypothesis that all are stationary is reasonable. We argue that nonlinear trend stationarity is the most likely alternative hypothesis for at least some of the real exchange rates because: (1) the strongest CIPS rejection occurs when quadratic trends are specified; (2) nonlinear time terms are statistically significant at the 0.10 level; (3) the actual CIPS statistics are more consistent with CIPS sampling distributions from bootstrapped nonlinear trend stationary processes than from linear trend or mean stationary processes.     

Trading frequency and asset pricing on the London Stock Exchange: Evidence from a new price impact ratio

This study proposes a new price impact ratio as an alternative to the widely used Amihud’s (2002) Return-to-Volume ratio. We demonstrate that the new price impact ratio, which is deemed Return-to-Turnover ratio, has a number of appealing features. Using daily data from all stocks listed on the London Stock Exchange over the period 1991–2008, we provide overwhelming evidence that this ratio, while being unequivocal to construct and interpret, is also free of a size bias. More importantly, it encapsulates the stocks’ cross-sectional variability in trading frequency, a relatively neglected but possibly important determinant of stock returns given the recently observed trends in financial markets. Overall, our findings argue against the conventional wisdom that there is a simple direct link between trading costs and stock returns by strongly suggesting that it is the compound effect of trading frequency and transaction costs that matters for asset pricing, not each aspect in isolation.     

The judgmental effects of strategy maps in balanced scorecard performance evaluations

We examine whether supplemental information displays affect decisions made using a common strategic performance measurement system, the balanced scorecard. A distinguishing feature of the balanced scorecard (BSC) is the number and diversity of its metrics. To effectively formulate a decision from such a complex information set, managers must view these measures within their strategic context ( [Kaplan and Norton, 1993] and [Kaplan and Norton, 1996] ). However, academic studies indicate that problems in communication and comprehension of the strategic logic underlying the scorecard hinder its implementation and use ( [Lipe and Salterio, 2000] , [Malina and Selto, 2001] , [Ittner et al., 2003a] and [Ittner et al., 2003b] ). We investigate whether a supplemental information display, in the form of a strategy map, results in performance evaluation judgments consistent with the recognition of relations between performance metrics and strategy. Strategy maps are causal diagrams depicting temporally-separate and non-linear relations between scorecard performance measures and overriding strategic objectives. As predicted, we find that performance evaluation decisions are more consistent with the achievement of strategic objectives when participants are provided with strategy maps.     

Estimating and validating a firm‐year‐specific measure of conservatism: Australian evidence

We provide new evidence on the asymmetric timeliness with which economic gains and losses are recognized in Australian financial reporting (i.e. conservatism), as well as some of the factors associated with variation in conservatism. We first derive, and then estimate and subsequently validate, a firm‐year‐specific measure of conservatism (C_Score) in the manner suggested by Khan and Watts (2007) . Our results indicate that conservatism is a pervasive feature of the Australian financial reporting environment. Conservatism is positively associated with stock return volatility, investment cycle length and prior period conservatism, and it is negatively associated with firm age, firm size and leverage. The results are an encouraging start for research into the causes and consequences of conservatism in Australian financial reporting.     

Accounting for human rights: Doxic health and safety practices – The accounting lesson from ICL

This paper is concerned with a specific human right – the right to work in a safe environment. It sets out a case for developing a new form of account of health and safety in any organisational setting. It draws upon the theoretical insights of Pierre Bourdieu taking inspiration from his assertion that in order to understand the “logic” of the worlds we live in we need to immerse ourselves into the particularity of an empirical reality. In this case the paper, analyses a preventable industrial disaster which occurred in Glasgow, Scotland which killed nine people¹ and injured 33 others. The paper unearths the underlying structures of symbolic violence of the UK State, the Health and Safety Executive and capital with respect to health and safety at work in the case. While dealing with one specific country (Scotland) and arguably an anomalous event we contend that Bourdieu's objective of constructing a special case of what is possible can equally be used to question health and safety regimes and other forms of symbolic violence across the globe.

Bourdieu (1998, p. 2) “My entire scientific enterprise is indeed based upon the belief that the deepest logic of the social world can be grasped only if one plunges into the particularity of an empirical reality, historically located and dated, but with the objective of constructing it as a “special case of what is possible,” as Bachelard puts it, that is, as an exemplary case in a finite world of possible configurations.

     

Overconfident individual day traders: Evidence from the Taiwan futures market

A specific day-trading policy in Taiwan futures market allows an investigation of the performance of day traders. Since October 2007, investors who characterize themselves as “day traders” by closing their day-trade positions on the same day enjoy a 50% reduction in the initial margin. Because we can identify day traders ex ante, we have a laboratory to explore trading behavior without the contamination of potential behavioral biases. Our results show that the 3470 individual day traders in the sample incur on average a significant loss of 61,500 (26,700) New Taiwan dollars after (before) transaction costs over October 2007–September 2008. This implies that day traders are not only overconfident about the accuracy of their information but also biased in their interpretations of information. We also find that excessive trading is hazardous only to the overconfident losers, but not to the winners. Last, we provide evidence that more experienced individual investors exhibit more aggressive day trading behavior, although they do not learn their types or gain superior trading skills that could mitigate their losses.     

Probability of information-based trading and the January effect

We investigate the seasonality in the probability of information-based trading (PIN)–return relationship, the ‘January PIN effect’. We find that on average stock returns decrease with PIN in January, in contrast to other calendar months. This pattern is more apparent for small stocks. We argue that this seasonality is related to the January effect. According to the analysis, the December selling pressure associated with the January effect decreases in PIN, especially for small stocks. This suggests that when the price bounces back in January, low-PIN stocks will exhibit a larger return within a small stock group, leading to the negative PIN–return pattern. Furthermore, this seasonality is not the same as other January anomalies associated with momentum and idiosyncratic risk.     

Is PIN priced risk?

Several recent papers assume that private information (PIN), proposed by Easley et al. [2002. Is information risk a determinant of asset returns? Journal of Finance 57, 2185–2221; 2004. Factoring information into returns. Working Paper, Cornell University], is a determinant of stock returns. We replicate Easley et al. (2002) and show that while PIN does predict future returns in the sample they analyze, the effect is not robust to alternative specifications and time periods. There is no evidence that PIN factor loadings predict returns or that PIN factor returns reflect future GDP growth. PIN exhibits no association with implied cost of capital derived from analysts’ earnings forecasts. Overall, our findings cast doubt on whether PIN reflects information risk systematically priced by investors.     

What affects accounting conservatism: A corporate governance perspective

This study explores the relationship between accounting conservatism and corporate governance. There are two competing perspectives about the possible relationship. One is that the demand for conservatism is greater in situations with more agency problems. Therefore, a weaker governance structure will lead to a more conservative accounting. An alternative perspective is that adequate governance results in better monitoring of management and hence will favor the implementation of conservative accounting. Using the firm-year specific C-Score developed by Khan and Watts [Khan, M., Watts, R.L., 2007. Estimation and validation of a firm-year measure of conservatism. Working Paper, Sloan School of Management, MIT, Cambridge], our empirical results indicate that firms with weaker governance structures tend to be more conservative. These findings are consistent with the view that conservatism is a substitute for other corporate governance mechanisms.     

Evidence on the role of accounting conservatism in monitoring managers’ investment decisions

Watts (2003), among others, argues that conservatism helps in corporate governance by mitigating agency problems associated with managers’ investment decisions. We hypothesize that if conservatism reduces managers’ex ante incentives to take on negative net present value projects and improves the ex post monitoring of investments, firms with more conservative accounting ought to have higher future profitability and lower likelihood (and magnitude) of future special items charges. Consistent with this expectation, we find that firms with more conservative accounting have (i) higher future cash flows and gross margins and (ii) lower likelihood and magnitude of special items charges than firms with less conservative accounting.
