SUMMARY In this research note, we examine the validity of the measures of auditor industry specialization in empirical archival audit research. Industry specialist auditors are auditors who have developed a specific expertise and are therefore able to provide high quality and more efficient services to their clients. Over the years, research scholars have developed a multiplicity of measures of industry specialization (ISP). We compare 30 ISP measures and find that the use of different ISP proxies results in inconsistent classifications of auditors as specialists. Using audit fee and earnings quality models, we further show that these inconsistencies have a significant effect on the inferences drawn from the models using ISP measures. We conclude that ISP measures exhibit a low degree of internal and external construct validity. This represents an important measurement challenge for researchers and casts some doubts on the robustness of prior empirical evidence found in auditor industry specialization research.

The rarity of females in leadership positions has been an important subject of study in economics research. The existing research on gender inequality has established that important variations exist across time and place and that these differences are partly attributable to the cultural differences regarding gender roles. The accounting research has also established that women are rarely promoted to the top of the Big Four audit firms (KPMG, Deloitte, PricewaterhouseCoopers and Ernst & Young). However, the majority of research in accountancy has focused on Anglo-Saxon contexts (the United States, the United Kingdom and Australia) or country case studies without explicitly considering the role that cultural variations may play. Because the Big Four are present in more than 140 countries, we argue that the accountancy research that attempts to explain gender disparities at the top of these organizations would benefit from considering cultural factors. Such research, however, faces a key methodological challenge-specifically, the measurement of the cultural dimensions that relate to gender. To address this challenge, we propose an emerging approach that uses the gender distinctions in language to measure cultural attitudes toward gender roles. The idea that language may capture gender roles and even influence their formation and persistence has been the focus of emerging research in linguistics and economics. To support our proposition, we follow two steps. First, we review the accounting research by performing a systematic query on the bibliographic databases of the accounting articles that study gender and language. Second, we present data regarding the diversity of the global boards of the Big Four and the diversity of the linguistic environments in which they operate. We find that half of the countries where the Big Four are present exhibit a sex-based grammatical system for their most-spoken language, while the other half of the countries do not exhibit this system. Our findings suggest that the use of language as a measure of culture is a novel approach in accounting research. We conclude by emphasizing some potential directions for future research, namely, studying the linguistic determinants of the rarity of females at the top of audit firms and exploring accountancy practices in countries with linguistically diverse environments, such as Canada or Belgium, among others. This article is published as part of a collection on the role of women in management and the workplace.
