In which financial markets do mutual fund theorems hold true?

The mutual fund theorem (MFT) is considered in a general semimartingale financial market S with a finite time horizon T, where agents maximize expected utility of terminal wealth. The main results are:

Statistical rehabilitation of improper correlation matrices

The simplest way to describe the dependence for a set of financial assets is their correlation matrix. This correlation matrix can be improper when it is specified element-wise. We describe a new method for obtaining a positive definite correlation matrix starting from an improper one. The expert's opinion and trust in each pairwise correlation is described by a beta distribution. Then, by combining these individual distributions, a joint distribution over the space of positive definite correlation matrices is obtained using Cholesky factorization, and its mode constitutes the new proper correlation matrix. The optimization is complemented by a visual representation of the entries that were most affected by the legalization procedure. We also sketch a Bayesian approach to the same problem.     

A time-varying common risk factor affecting corporate yield spreads

A time-varying common risk factor affecting corporate yield spreads is modelled by extending a panel data model. The panel data model accommodates a common factor, which is associated with time-varying individual effects. The factor multiplied by a bond-specific unobservable is identified as a systematic risk premium. In disentangling the systematic risk premium, both credit and liquidity risks are evaluated; the credit risk is assessed by bond rating, and the liquidity risk is indirectly measured by discrepancy in quoted yields by brokerage firms. Parameters are estimated by the generalized method of moments procedure. The model is tested on the corporate bond market in Japan. Empirical results show that the time-varying common risk factor is successfully estimated together with credit and liquidity risks.     

Principles‐Based Reasoning about Accounting Estimates

This article proposes a key principle and related concepts for reasoning about accounting estimates. The reasoning is consistent with a principles‐based professional judgment framework proposed by Ross Skinner and the Institute of Chartered Accountants of Scotland. The principle deals with reasonable ranges and related risk assessments in the audit of accounting estimates. It does so by using concepts first introduced by Boritz and Skinner and updates them for the requirements of CAS/ISA No. 540 and International Financial Reporting Standards. The article identifies the conditions for the existence of the benchmark ranges proposed by Smieliauskas in identifying fairly presented estimates. The need for a professional judgment framework and related guidance has been recognized recently by the International Federation of Accountants, a 2010 EU Green Paper, and the Public Company Accounting Oversight Board as a result of challenges auditors have been facing in the current reporting environment. This recognition echoes calls first made by Ross Skinner in his pioneering 1995 article, and reinforced by the FASB/IASB 2006 proposal for principles‐based accounting standards.     

Cost of monitoring and risk taking in the money market funds industry

Increasing the cost associated with gathering information can hamper the monitoring activity of the market even when information remains public. Using the 2015 US money market funds (MMFs) reform as a quasi-natural experiment, I find a positive effect of removing information requirements over credit ratings on the allocation by MMFs toward securities rated as second tier. The effect is driven by monitored MMFs catering to retail investors and by monitored MMFs that do not voluntarily report credit ratings after the reform. The verfied increase in the relative demand by MMFs for second tier securities is associated with a decrease in the spread paid at issuance by second tier commercial paper.     

Is investment decision-making influenced by perceptions relating to auditors’ client dependence and amount of audit fees?

The objectives of this study are to examine whether investing decisions are affected by knowledge about the auditor's revenue dependence on a client and whether the amount spent by a company on audit fees affects decisions to invest in the company. A behavioral experiment is conducted where risk assessments and investing decisions are made for four hypothetical investing scenarios. The study finds that investing decisions are affected by knowledge about an auditor's revenue dependence on a client, but are not affected by knowledge about the size of a client's audit fees.     

损有余而补不足——从老子的哲学观论社会财富分配机制

老子认为“损有余而补不足”是一种自然法则;“道法自然”是老子哲学的最终归宿。人类社会要和谐,就必须在社会财富分配上遵循“损有余而补不足”这一自然法则,不要使社会出现“损不足以奉有余”的两极分化状态,以免付出沉重的代价。以老子的哲学观审视现实的社会财富分配,一个良性的社会财富分配机制应当是以市场经济手段为基础,以国家福利手段为保障,以社会慈善手段为补充。在这种机制的作用下,社会财富分配两极分化的张力得到有效的消减,社会各阶层对财富的占有达到相对均衡,从而使社会的和谐状态得以持久的保持。     

Optimal insurance and reinsurance policies chosen jointly in the individual risk model

The paper studies the so-called individual risk model where both a policy of per-claim insurance and a policy of reinsurance are chosen jointly by the insurer in order to maximize his/her expected utility. The insurance and reinsurance premiums are defined by the expected value principle. The problem is solved under additional constraints on the reinsurer’s risk and the residual risk of the insured. It is shown that the solution to the problem is the following: The optimal reinsurance is a modification of stop-loss reinsurance policy, so-called stop-loss reinsurance with an upper limit; the optimal insurer’s indemnity is a combination of stop-loss- and deductible policies. The results are illustrated by a numerical example for the case of exponential utility function. The effects of changing model parameters on optimal insurance and reinsurance policies are considered.     

PERFORMANCE BASED COMPENSATION IN HEALTH CARE — A SWEDISH EXPERIENCE

In recent years most attempts at reforming health care in Sweden appear to be guided by ideals of decentralization and market orientation. Based on a longitudinal case study of five clinics in a large university hospital this paper questions the general applicability of the market framework in health care. The case story describes how a traditional overall budgeting system was replaced by a performance compensation system in which the clinics were paid a fixed price per unit produced. The new system involved the use of results, balance and funds statements and was also soon to be accompanied by another major reform introducing a purchaser-provider split organization in the county. The story ends by showing how the bold ambitions of establishing strict market like contracting forms fail to materialise and eventually get abandoned.     

A stochastic differential game for optimal investment of an insurer with regime switching

We introduce a model to discuss an optimal investment problem of an insurance company using a game theoretic approach. The model is general enough to include economic risk, financial risk, insurance risk, and model risk. The insurance company invests its surplus in a bond and a stock index. The interest rate of the bond is stochastic and depends on the state of an economy described by a continuous-time, finite-state, Markov chain. The stock index dynamics are governed by a Markov, regime-switching, geometric Brownian motion modulated by the chain. The company receives premiums and pays aggregate claims. Here the aggregate insurance claims process is modeled by either a Markov, regime-switching, random measure or a Markov, regime-switching, diffusion process modulated by the chain. We adopt a robust approach to model risk, or uncertainty, and generate a family of probability measures using a general approach for a measure change to incorporate model risk. In particular, we adopt a Girsanov transform for the regime-switching Markov chain to incorporate model risk in modeling economic risk by the Markov chain. The goal of the insurance company is to select an optimal investment strategy so as to maximize either the expected exponential utility of terminal wealth or the survival probability of the company in the ‘worst-case’ scenario. We formulate the optimal investment problems as two-player, zero-sum, stochastic differential games between the insurance company and the market. Verification theorems for the HJB solutions to the optimal investment problems are provided and explicit solutions for optimal strategies are obtained in some particular cases.     

Financial Capital and Taxation Policy*

This paper suggests a relatively simple analytical framework for taxing all financial arrangements. The debt/equity distinction is determined by the contingency principle. The accruals/realisation distinction is determined separately by the volatility principle. The capital/revenue character distinction is effectively removed directly or by a character hedging regime. Hybrids, synthetics, hedging arrangements and other portfolios are tax‐assessed on an aggregate, rather than a bifurcated, basis. The framework could be applied to both classical and dividend‐imputation‐based business tax systems.     

Discretionary write-downs,write-offs,and other restructuring provisions: a signaling approach

This paper introduces a model seeking to explain the discretionary write-downs, write-offs, and other restructuring provisions reported by managers. The model comprises a firm, a manager, and a financial market. The firm is about to be restructured. The manager has some private information about the likelihood of success of his restructuring action. The manager may recognise all or part of the expenditure associated with his future restructuring action by reporting a discretionary restructuring provision. The manager chooses whether or not to report a provision, recognising the impact of the provision on his compensation. The paper shows how, under certain conditions, the manager may credibly communicate his private information to investors through his provision policy. Testable implications are consistent with the empirical evidence reported by Strong and Meyer (1987), Elliott and Shaw (1988), and Zucca and Campbell (1992).     

Explaining abnormal returns in stock markets: An alpha-neutral version of the CAPM

This paper develops a behavioural asset pricing model in which traders are not fully rational as is commonly assumed in the literature. The model derived is underpinned by the notion that agents’ preferences are affected by their degree of optimism or pessimism regarding future market states. It is characterized by a representation consistent with the Capital Asset Pricing Model, augmented by a behavioural bias that yields a simple and intuitive economic explanation of the abnormal returns typically left unexplained by benchmark models. The results we provide show how the factor introduced is able to absorb the “abnormal” returns that are not captured by the traditional CAPM, thereby reducing the pricing errors in the asset pricing model to statistical insignificance.     

Continuity and Discontinuity in Accounting Technology in Danish State Institutions

The development of accounting technology in the Danish state sector is characterised by episodes of disruption and the longevity of certain principles that define accounting's accountability as involved in producing the state as a unit, as providing a continuous concern for productivity, and as providing the means by which a parliamentary democracy may work. The episodes of disruption may often repair on this trinity of issues. The recent transformations are radical as they introduce a new form of management via individualised 'accounting-cultured' institutions and managers. They do so via a heightened emphasis on a core technology already in place supplemented by a new mode of output orientation rather than input orientation via a Company Accounts . In addition to reporting on spending, this set of accounts introduced a series of non-financial measures such as productivity, quality, and customer satisfaction.     

The Quasi-split Effect, Active Insiders and the Italian Market Reaction to Equity Rights Issues

The positive market reaction at the announcement of most European rights issues can be explained by two major factors which distinguish them from a US public offering: active insiders, and a quasi-split effect which signals a large increase in the dividend yield. An analysis of 428 Italian rights offerings and an event study involving 82 observations in the 1980–94 period show that Italian insiders are completely 'active', and almost 85 % of the equity rights issues result in a dividend yield increase, which corresponds to the quasi-split effect in approximately 40 % of the issues. The dividend yield rises, on average, by a significant +61 % after a combined rights offering and by a significantly lower +20 % following a fully-paid rights issue. The market reaction to the announcement is significantly positive for combined rights offerings (+ 2.77 %) and positive, but not significant, for the whole sample (+ 0.79 %). The dividend increase signalled by the quasi-split effect explains almost 30 % of the abnormal returns' cross-sectional variation and it is the only significant explanatory variable.     

A multinational test of determinants of corporate disclosure

This paper develops a model of cultural, national, and corporate factors that influence the financial disclosure of corporations. This model is then tested empirically using a sample of companies from 33 countries. The paper extends the literature on disclosure by considering a larger number of variables that represent determinants of disclosure and by empirically testing the model using a larger number of countries than prior studies. The model is tested using disclosure scores included in International Accounting and Auditing Trends. The model considers the influence of culture, national political and economic systems, and corporate financial and operating systems on the amount of corporate financial disclosure. The results of the regression model indicate that disclosure is influenced by culture, national systems, and corporate systems. The model developed is shown to provide a reasonably good explanation of the disclosure decision. Differences among the components of the model help explain differences in observed financial disclosure between companies in different countries and between companies within the same country. The results indicate that the financial-disclosure decision for a company is complex and influenced by many national and corporate factors.     

Stock recommendations and investment portfolio formation: A study in the Brazilian market

The stock analysts have a relevant role in the capital market, since, directly or indirectly, they contribute to the paper pricing and to the composition of the investment portfolio. The purpose of this study is to verify if it is possible to obtain extraordinary returns, above those offered by a market portfolio, with the monitoring of the stock recommendations issued by Brazilian capital market analysts, one of the most important in Latin America. Based on a wide range of consensual recommendations concerning the period from 2000 to 2010, and with the monitoring of the historical series of paper returns covered by the analyses, the performance of two portfolios were compared, one formed by stocks that received favorable and the other one formed by stocks that received unfavorable analyst recommendations. The results showed bias in recommendations, since there is, systematically, a greater number of favorable against unfavorable recommendations. The results mainly showed that the analysts were unable to identify the stocks that actually offered greater returns within the period considered.     

Perceptions of postretirement benefit obligations by bond rating analysts

This research examines the measurement and impounding of alternative measures of a corporation's other postretirement benefits obligation (OPEBs) by an important segment of the capital markets. The Kaplan and Urwitz (1979) model is used as a benchmark from which to assess the importance of an added OPEB variable in the bond rating process. Using the corporate bond rating as the dependent variable, multiple measures of the OPEB obligation are inserted individually as an added independent variable into an N-chotomous probit model. The results for 1987 and 1988 indicate that measures calculated from publicly available information produce highly significant results. The developed postretirement liability measures are found to provide relevant and material information regarding the risk level of a firm's bonds as represented by its bond rating. This insight concerning the additional risk represented by a firm's postretirement benefits is beyond that supplied by the firm's pension information. This suggests that the additional investor default risk attributed to a firm's OPEB can be reasonably proxied by data found in the company's annual report footnote disclosures.     

The emancipatory potential of extinction accounting: Exploring current practice in integrated reports

This paper adopts a normative approach to develop a dynamic form of corporate reporting designed to deal with the threat posed by mass extinction of species. The proposed reporting framework is intended to show how a type of accounting – which is referred to as extinction accounting – can and should be used to drive positive corporate change and prevent the loss of species. The framework is inspired by both an anthropocentric and deep ecological view on nature and draws on accountancy’s emancipatory potential rather than attempting to find a substitute for current technologies of accounting and accountability. The prior literature on biodiversity and emancipatory accounting is complemented by showing how an innovative form of reporting on a specific environmental issue can be operationalised and used in the short-term to respond to the threats posed by mass extinction.
