R-estimation of the parameters of a multiple regression model with measurement errors

We consider the theory of R-estimation of the regression parameters of a multiple regression models with measurement errors. Using the standard linear rank statistics, R-estimators are defined and their asymptotic properties are studied as robust alternatives to the least squares estimator. This paper fills the gap of the rank theory for the estimation of regression parameters with measurement error models. Some simulation results are presented to show the effectiveness of the R-estimators.     

Estimation of parameters of parallelism model with elliptically distributed errors

In this paper we consider some improved estimators of the intercept and slope parameters in a parallelism model with errors belonging to a sub-class of elliptically contoured distributions. We derive the exact bias, MSE matrices and quadratic risk expressions for these estimators. It is shown that the dominance properties of these estimators are the same as under normal theory. Further, it is shown that the shrinkage factor of the Stein estimators is robust with respect to the regression parameters and unknown mixing distributions.     

Russia–Ukraine crisis: The effects on the European stock market

We examine the effect of the Russia–Ukraine crisis on the European stock markets. Because of increased political uncertainty, geographic proximity and the ramifications of the fresh sanctions imposed on Russia, the European stock markets tended to react negatively to this crisis. We find that on 21 February 2022, when Russia recognized two Ukrainian states as autonomous regions, European stocks incurred a significant negative abnormal return. Moreover, the negative stock price reactions continued in the post-event period. The magnitude of the stock price reactions to this crisis exhibits considerable variation across industries, countries and size of the company.     

Fair Value Exposure,Changes in Fair Value and Audit Fees: Evidence from the Australian Real Estate Industry

This paper investigates the relationship between audit fees and both fair value exposure and changes in fair value of investment properties. The study is motivated by the limited and inconclusive evidence on the effect on audit fees of full fair value reporting for illiquid assets. Using hand‐collected data from the Australian real estate industry, we find a negative (positive) association between audit fees and fair value exposure (changes in fair value of investment properties). Our findings also indicate that the use of unobservable inputs in fair value estimates for investment properties does not significantly increase audit risk and audit fees. Further, we find that audit fees are higher for firms with fair values of investment – properties estimated by external and mixed valuers – compared to firms with fair values estimated by directors alone. This study enriches the audit fee literature by documenting auditors’ pricing decisions in an area that involves significant estimation and valuation risks.     

Impact of IFRS in New Zealand on Accounts and Earnings Quality

The impact of the adoption of International Financial Reporting Standards (IFRS) on the accounts and the quality of earnings of New Zealand firms is examined. Our analysis of IFRS adjustments for the last period under pre‐IFRS NZ Generally Accepted Accounting Principles (GAAP) reveals that total assets, total liabilities and net profit were significantly higher under IFRS than under pre‐IFRS GAAP. Profit and equity under IFRS were increased by adjustments for goodwill and other intangibles and investment property, and decreased by adjustments for employee benefits and share‐based payments. Using data for 2002–2009, we find that absolute discretionary accruals were significantly higher under IFRS than under pre‐IFRS NZ GAAP, suggesting lower earnings quality under IFRS than under pre‐IFRS NZ GAAP. However, we find no significant differences in signed discretionary accruals and the ability of earnings to predict one‐year‐ahead cash flows between pre‐IFRS NZ GAAP and IFRS. These results are consistent across alternative measures of accruals quality, sample selection and whether firms elected to adopt IFRS in 2005 rather than comply with them in 2007.

The evolution of auditing： An analysis of the historical development

This paper aims to analyze the development of auditing. It is found that auditing has evolved through a number of stages. In the mid 1800s to early 1900s, the audit practice was considered as ＂traditional conformance role of auditing＂. However, for the past 30 years, the auditor has been playing an ＂enhancing role＂. Today, auditors are expected not only to enhance the credibility of the financial statement, but also to provide value-added services. Nevertheless, following extensive reform in various countries as a result of the collapse of big corporations, it is expected that the role of auditors will converge. It is evident that the paradigm about auditing has shifted over the years and it is likely to continue shifting in the future.     

Social responsibility in micro businesses in an African context: Towards a theoretical understanding

Small businesses often engage in social responsibility (SR) without knowing it or without referring to their actions as SR. This is particularly the case in developing countries where the idea of SR is seen as synonymous with philanthropy. While the literature on small business social responsibility is growing, our understanding of the context-specific determinants of responsible practices in microbusinesses (those that employ less than 10 employees) that dominate the business landscape in many developing countries is still limited. In this paper, we address this gap and offer a theoretical understanding of how microbusiness owner-managers understand and approach SR by drawing on rich qualitative data collected from Nigeria—Africa's largest economy. We utilise Social Representations Theory to understand (1) how and why microbusiness owner-managers limit their understanding of SR to philanthropic activities and (2) the wide range of practices, including philanthropic activities, that account for their overall Responsible Business Practices (RBPs)—those practices that enable them to act responsibly towards their stakeholders and/or operating environments. We find that owner-managers' representations of SR are anchored primarily on an idiosyncratic ethical tendency and inclination towards the creation of social/communal harmony by ‘giving back to society’ and objectified via actions deriving from three ‘giving back’ orientations, namely Core Philanthropism, Social Problem Solving, and Empowering. We model microbusiness owner-managers' RBPs, highlighting the intersectional interplay of the voluntary (SR as philanthropy) and non-voluntary (self-regulatory and legal) dimensions of RBPs. Finally, we discuss the key findings in relation to the extant literature and to policymakers and managers.     

History of microfinance in Bangladesh: A life cycle theory approach

This study aims to conceptualise and document the historical evolution of microfinance in Bangladesh using the life cycle theory (LCT). Based on the LCT nomenclature, the microfinance sector in Bangladesh shows characteristics broadly consistent with the saturation phase (2006–2015) – which potentially has adverse impacts on both microfinance clients and institutions. The maturity phase (1996–2005) of microfinance has corresponded with competition and several innovations (financial and non-financial). However, the saturation phase sees increasing presence of uncoordinated microfinance institutions and expansion of multiple borrowing, as well as commercialisation and ‘mission drift’, which constitute important challenges for the regulatory authority and management of microfinance institutions.
