Ranking the strategic actions of Iran mobile cellular telecommunication using two models of fuzzy QFD

Mobile cellular telecommunication success in target markets first requires ranking the customer’s expectations and then prioritizing the engineering characteristics (ECs) to meet the expectations. In this paper, two prioritization models based on quality function deployment (QFD) are developed to rank the strategic actions (SAs), or the ECs of Iran mobile cellular telecommunication. QFD is a widely used customer-driven tool for which the success of its applications may be the result of some of its benefits, such as greater customer focus. It uses a matrix called House of Quality (HOQ) to translate Customer Attributes (CAs) into ECs. However, due to the high degree of subjectivity in constructing the HOQ, the application of fuzzy logic provides an efficient tool to handle the subjective assessments. On the other hand, taking into consideration the gap between the current state and the positive ideal state for each CA, TOPSIS is used to rank CAs in a first model. In addition, in a second model, using the analytic hierarchy process (AHP), more criteria are taken into consideration in ranking CAs. Also, a fuzzy utility factor, B_j, is used to rank SAs in both models. Both presented models have the ability to capture the vagueness of human thinking style, and let customer oriented organizations, such as MCI, derive benefits from the voice of the customer (VOC) in a more expressive way.

Earnings management around founder CEO reappointments and successions in family firms

This paper studies reappointment of a chief executive officer (CEO) and succession events in listed family firms with an incumbent family CEO. We explore whether family firms with a founder CEO are more likely to engage in earnings management preevent than other family firms. We find evidence of preevent upward earnings management for firms that reappoint their founder CEO but no for other family firms. These findings suggest that the costs and benefits from earnings management change around founder CEO reappointments in family firms. Investors, auditors, policymakers and regulators should be aware of the temptation of founder CEOs to inflate earnings preceding their reappointment.     

Nudging toward diversity in the boardroom: A systematic literature review of board diversity of financial institutions

Going beyond the mere gender diversity in the boardroom, this systematic review comprehensively covers the research on board diversity of financial institutions. More specifically, we cover gender diversity, as well as other characteristics of diversity, such as nationality, age, tenure, experience, education, ethnicity, and religion. A systematic literature review was employed using Scopus and Web of Science databases, covering all publications until May 2020, which resulted in 91 studies from 66 top-ranked journals in accounting, finance, and economic fields. We analyze them based on the journal, methodology, research construct questions, and theoretical perspectives. Our results highlight the substantial knowledge gaps and the inconsistent findings of prior studies on several aspects of the field, suggesting avenues for further studies in terms of research designs, settings, scope, and theories. We argue that there is a need to explore other board diversity attributes rather than focusing on the gender diversity of the boards of financial institutions to achieve sustainable development. Also, more work is outlined on topics related to board diversity of financial firms that receive limited attention from scholars, such as (but not limited to) environmental performance, capital structure, intellectual capital, innovation and earnings quality of financial institutions, as well as the indirect effect of policy settings.     

Industrial research and development and real exchange rate depreciation in a small open economy

To examine how changes in relative national prices affect innovation input, this paper studies the impact of changes in industry-specific effective real exchange rates on industrial R&D expenditures in Korea. In particular, it explores the heterogeneous responses of industries with different export intensities. Employing dynamic panel data estimation techniques, the results suggest that among industries with medium levels of export intensity a lagged depreciation in industry-specific effective real exchange rate leads to a decline in contemporaneous industry-level R&D expenditures. However, this adverse effect is insignificant for industries that either mostly serve the domestic markets or that are heavily engaged in foreign markets.
