Non-audit services provided to audit clients,independence of mind and independence in appearance: latest evidence from large UK listed companies

This paper investigates whether the provision of non-audit services (NAS) to audit clients impairs auditor independence of mind and independence in appearance. The main contributions of this paper are in terms of its timeliness with respect to regulatory changes, the simultaneous examination of both forms of auditor independence and the methodological innovation whereby it uses a variable derived from the level of abnormal audit fees as a moderating variable in order to capture the direct impact of the NAS fee level on auditor independence as well as how its influence is moderated by the level of unexpected audit fees. Our results indicate that auditor independence of mind is compromised by the size of NAS fees, particularly for clients who pay below the level of expected audit fee. The stock market perceives that auditor independence is compromised by NAS fees but, at the same time, additional tests indicate that there are benefits that accrue from NAS and, in particular, the relation between return and non-discretionary net income is increasing in NAS fees. The balance of evidence suggests that the European Union is correct in undertaking some reform of the auditing market.     

The impact on the market for audit services of aggressive competition by auditors

Supporters of direct uninvited solicitation activities argue that clients can make more informed choices of auditors when auditors are allowed to solicit prospective clients. In banned markets, auditors are allowed to submit bids to provide audit services only when invited by the client. This study provides theoretical models that examine the efficiency of client–auditor alignments in the banned and allowed market. We identify conditions under which realignment differences between the two markets occur and derive client losses in the banned market as compared to the allowed market. We also identify conditions under which independence may be impaired in the allowed market, consistent with the claims of solicitation opponents. However, we believe that, in view of the potential positive effects related to audit pricing and client–auditor alignment, restrictions on advertising or direct uninvited solicitation are not necessarily indicated. Instead, regulators or market mechanisms should insure that the independence (truth-telling) condition is so readily satisfied as to be virtually irrelevant. This can happen in one of two ways: (a) increased scrutiny, leading to an increased likelihood of discovery, or (b) increased penalties when an audit failure is discovered, leading to increased costs of an audit failure, or both.     

Is mandated independence necessary for audit quality?

Independence (in fact as well as in appearance) is widely thought to be necessary for the quality of audits, and audit quality is often equated with independence. Private incentives to demand (and supply) independent certification of financial statements are thought to be insufficient, thus the need to mandate independence through regulation. This study presents data from a field experiment on the unregulated market for certification of baseball cards to assess the role of independence vis-à-vis other auditor attributes such as competence, price, and service on audit quality. In our field experiment, we examine prices of baseball cards sold on eBay with or without third party certification. In addition, the certifier was either independent or deeply immersed in providing other services to market participants. We find that market participants pay a significant premium for certified cards. Certifiers who are deeply immersed (and therefore apparently less independent) also provide higher quality service in the form of being stricter graders, command larger price premiums, and dominate in market share. Implications for independence and audit quality are discussed.     

Nonparametric testing of the high-frequency efficiency of the 1997 Asian foreign exchange markets

Sherry’s nonparametric pattern tests for neural information processing are used to ascertain if the Asian foreign exchange (FX) rates followed random walks [Sherry, C.J., 1992. The Mathematics of Technical Analysis: Applying Statistics to Trading Stocks, Options and Futuresm Probus, Chicago]. The stationarity and serial independence of the price changes are tested on minute-by-minute data for nine Asian currencies from 1 January 1997 to 30 December 1997. The efficiency of these FX markets before and after the Asian currency ‘regime discontinuity’ are compared. The Thai baht (THB), Malaysian ringgit (MYR), Indonesian rupiah (IDR) and Singapore dollar (SGD) exhibited non-stationary behavior during the entire year, and gave evidence of a trading regime break, while the Phillipines’ peso (PHP), Taiwan dollar (TWD), Japanese yen (JYP) and German deutschmark (DEM) remained stationary, with the US dollar (USD) as numeraire. However, each half-year regime showed stationarity, indicating stable and nonchaotic trading regimes for all currencies, despite their high volatilities, except for the MYR, which exhibited non-stationarity in the second half of 1997. The Thai baht traded nonstationarily in the first half of 1997, but stationarily in the second half. while the TWD reversed that trading pattern. Based on Sherry’s four tests for serial independence, none of the currencies exhibited complete independence. Thus no Asian currency market—including the JYP—exhibited complete efficiency in 1997, in particular when compared with the highly efficient DEM. Remarkably, the PHP remained as efficient as the JYP throughout 1997.     

Board structure and market performance: Does one solution fit all?

We investigate the relationship between internal corporate governance and market performance across multiple countries, utilizing a comprehensive data set comprising 77,440 firm observations from 15 European Union countries over the period 2002-2018. Specifically, we examine the impact of board characteristics, including size, independence, gender diversity, CEO duality, and classified boards, on market performance. Our findings reveal that CEO duality is generally negatively related to returns, whereas independent directors and board diversity are positively related to market performance. We observe a positive association between staggered boards and market performance as well as Tobin's Q, aligning with the EU's emphasis on stakeholder investments. Upon analyzing the data at the country level, we identify that the links between board structure and performance vary by country, and there isn't a single variable that is consistently related to market returns or Tobin's Q. These divergent findings indicate that there is no universally applicable corporate governance solution that can be recommended for companies throughout Europe.     

A Simple Implicit Measure of the Effective Bid-Ask Spread in an Efficient Market

In an efficient market, the fundamental value of a security fluctuates randomly. However, trading costs induce negative serial dependence in successive observed market price changes. In fact, given market efficiency, the effective bid-ask spread can be measured by $\text{Spread}=2\sqrt{?\text{cov}}$ where “cov” is the first-order serial covariance of price changes. This implicit measure of the bid-ask spread is derived formally and is shown empirically to be closely related to firm size.     

Friction in the trading process and the estimation of systematic risk

This paper considers how estimates of the market model beta parameter can be biased by friction in the trading process (information, decision, and transaction costs) that (a) leads to a distinction between observed and ‘true’ returns; (b) causes observed returns to be generated asynchronously for a set of interdependent securities; and (c) thereby introduces serial cross-correlation into security returns. Several propositions are derived from which consistent estimators of beta are obtained, and the effect of differencing interval length on beta estimates is specified. The formulation is contrasted with the related analyses of Scholes-Williams (1977) and Dimson (1979).     

A Formal Model of Auditor Independence Risk

Although the literature on auditor independence is extensive, an accepted comprehensive theory, framework or model of auditor independence risk does not exist. This paper develops a formal model of auditor independence risk that may be used to begin a more rigorous investigation of auditor independence and various factors that are thought to affect this risk. Overall, our analytical results show that integrity is the key variable in minimising independence risk. In addition, in cases where integrity could be questioned, independence risk is positively affected by professional standards that are perceived to be effective and potentially negatively affected by certain client characteristics and auditor incentives.     

Client importance and audit partner independence

We use data from Taiwan where audit partners are required to sign audit reports to examine whether audit partners compromise their independence for economically important clients. Uniquely, we include both listed and unlisted clients in audit partners’ client portfolios and separately study these clients for Big N and non-Big N auditors. We employ multiple proxies for auditor independence, including various abnormal accruals measures, the propensity of audit partners to issue modified audit opinions, and the probability that clients meet or just beat earnings targets. We fail to find evidence that Big N audit partners compromise their independence for economically important clients; however, we find such evidence for non-Big N auditors. Our results are robust to a battery of sensitivity analyses. While our inferences are limited to the Taiwanese capital market, our study may be of interest to market participants and regulators in other well developed capital markets.     

Value or volume strategy?

This article reports a study that analyzes financial data for US firms listed during 1996–2005 to examine the asymmetric effects of the informative variables on stock returns between the boom and bust conditions in stock price. The study includes analysis of changing distribution of stock returns across stocks and over time by using a quantile regression (QR hereafter) model and comparison of the results with OLS and LAD estimates. The present empirical results indicate that market investors are more influenced by the fundamental variable, such as P/E ratios, derived from the value strategy when the stock they invest is in experience of a large fall in price. Conversely, when the stock price is hugely rising, market participants increase the loading of the effect of trading volume. Last, although the market returns have a significantly positive impact on the individual stock returns, we further indicate that the systematic effects involved in the market returns are much more notable when this specific stock is experiencing a recession condition in price.     

AN IMPLICIT MEASURE OF THE EFFECTIVE BID-ASK SPREAD: A NOTE

We extend Roll's study of the effective bid-ask spread in an efficient market environment by allowing for serially correlated order arrival and quote behavior. This extension results in a more general effective bid-ask spread measure, which precludes imaginary spreads and includes Roll's measure as a special case when the serial correlation is zero. This new measure is related to the length of the measurement interval due to the serial correlation, and thus has the potential to explain the previously observed differential between weekly and daily derived spreads.     

The Determinants of Sukuk Market Development

The objective of this article is to empirically investigate the structural, financial, developmental, institutional, and macroeconomic determinants of Sukuk market development for a sample of 13 countries over the period 2001–2013. We employ the Generalized Method of Moments (GMM) procedure to tackle the problems of endogeneity of lagged dependent variable, heteroscedasticity, and serial correlation in the residuals. Our results suggest that a combination of structural, financial, and institutional factors seem to exert a significant effect on Sukuk markets. Indeed, larger economic size, higher proportion of Muslims in the population, better investment profile (IP), and lower corruption are associated with larger Sukuk markets, while higher interest rate spread is negatively related to Sukuk market development.     

Modelling the behaviour of the new issue market

This paper analyses the time series behaviour of the initial public offering (IPO) market using an equilibrium model of demand and supply that incorporates the number of new issues, average underpricing, and general market conditions. Model predictions include the existence of serial correlation in both the number of new issues and the average level of underpricing, as well as interactions between these variables and the impact of general market conditions. The model is tested using 40 years of monthly IPO data. The empirical results are generally consistent with predictions.     

Insurance intermediation — Theoretical analysis and practical issues in the european market

This paper studies intermediation between consumers and providers of insurance. Different types of intermediaries are distinguished and investigated in the light of recent market dynamics in Germany and elsewhere in Europe, in particular concentration and the trend towards one-stop finance. Intermediaries’, the insurance providers’ and the consumers’ strategic options are evaluated with a focus on the incentive problems caused by an intermediaries double principal-agent relationship with insurance providers and consumers. Criteria for an intermediary’s independence, which is often aggressively advertised without transparent justification, are developed. It is argued that performance and stability of the market could be improved by well-specified levels of independence in insurance intermediation which are to be verified by regulation authorities and / or private rating agencies.     

The Banking Sector,Government Bonds,and Financial Intermediation: The Case of Emerging Market Countries

This paper develops an analytical framework to explore how financial-sector characteristics shape the terms and the scale of public borrowing in emerging market economies. We find that the more competitive the banking sector and the more liquid and deeper the deposit market, the better are conditions in the public securities market. We also show that the greater the central bank independence, the higher the cost of public borrowing. Furthermore, our results suggest that, in countries where banks rely significantly on foreign currency financing, the greater the government's reliance on bank lending, the greater is its exposure to exchange rate risk.     

Pricing dynamic binary variables and their derivatives

Many important assets or business ventures have cash flows that are not derivatives of a market security but are nevertheless dependent on some variable that is correlated with market prices. This includes many real option projects. This paper presents a methodology using a binary framework for pricing such assets by projection onto the market space. Under certain conditions, the result has the property that, given this price process, no risk-averse investor would choose to invest in this asset either long or short.     

全球金融周期、美国货币政策与“三元悖论”

全球金融周期存在的背景下“三元悖论”是否依然成立充满争议。本文通过构建包含银行与金融摩擦的两国DSGE模型,为考察全球金融周期的形成提供了理论依据。美国货币政策通过资本流动传导到外围国金融市场,使外围国信贷利率、银行风险承担以及杠杆率与美国银行趋同,形成全球金融周期。金融渠道的传导速度快于实体经济渠道导致外围国国内经济周期与金融周期相背离,外围国想要稳定经济就不得不与美国保持同向的政策利率变化,货币政策独立性将不再存在。随着全球经济一体化进程加速,估值效应的作用越来越明显,浮动汇率制度并不能隔离全球金融周期的影响也无法保证货币政策的独立性。在资本账户开放的情况下,外围国金融市场越不发达,受全球金融周期的影响越大,货币政策越不独立。     

Spanning and efficiency in an economy with collective and individual risks

Much of the literature on incomplete markets emphasizes the study of conditions under which security market returns, either with or without derivative securities, span some exogenous set of cash flows. It is argued here that the only set of exogenous cash flows to which this literature is applicable are those that are contingent on existing assets' returns. The reason for this is that cash flows created by firms' production decisions are likely to be influenced by individual (unique) risk that is not incorporated into the market's existing information structure. The results of this article show that, if individual risk is pervasive, efficient allocation is likely to be achieved only in a large asset market which allows for the diversification of individual risk. The conditions for such diversification are derived and their implications discussed.     

Forecasting Surrender Rates Using Elliptical Copulas and Financial Variables

A multistage stochastic model to forecast surrender rates for life insurance and pension plans is proposed. Surrender rates are forecasted by means of Monte Carlo simulation after a sequence of GLM, ARMA-GARCH, and copula fitting is executed. The model is illustrated by applying it to age-specific time series of surrender rates derived from pension plans with annuity payments of a Brazilian insurer. In the GLM process, the only macroeconomic variable used as an explanatory variable is the Brazilian real short-term interest rate. The advantage of such a variable is that we can take future market expectation through the current term structure of interest rates. The GLM residuals of each age/gender group are then modeled by ARMA-GARCH processes to generate i.i.d. residuals. The dependence among these residuals is then modeled by multivariate Gaussian and Student's t copulas. To produce a conditional forecast on a stock market index, in our application we used the residuals of an ARMA-GARCH model fitted to the Brazilian stock market index (Ibovespa) returns, which generates one of the marginal distributions used in the dependence modeling through copulas. This strategy is adopted to explain the high and uncommon surrender rates observed during the recent economic crisis. After applying known simulation methods for elliptical copulas, we proceeded backwards to obtain the forecasted distributions of surrender rates by application, in the sequel, of ARMA-GARCH and GLM models. Additionally, our approach produced an algorithm able to simulate multivariate elliptical copulas conditioned on a marginal distribution. Using this algorithm, surrender rates can be simulated conditioned on stock index residuals (in our case, the residuals of the Ibovespa returns), which allows insurers and pension funds to simulate future surrender rates assuming a financial stress scenario with no need to predict the stock market index.     

Adaptive market efficiency of agricultural commodity futures contracts

In this paper we investigate the adaptive market efficiency of the agricultural commodity futures market, using a sample of eight futures contracts. Using a battery of nonlinear tests, we uncover the nonlinear serial dependence in the returns series. We run the Hinich portmanteau bicorrelation test to uncover the moments in which the nonlinear serial dependence, and therefore adaptive market efficiency, occurs for our sample.
