Market share and market size variances in a multi-product environment: An evaluation of competing formulations

Market share and market size variances are typically included in cost and managerial accounting texts in the discussion on sales variances. Shank and Churchill (1977) introduced a widely-adopted methodology wherein these variances are equal to the sales quantity variance, with the sales mix variance accounting for the entire variation in sales mix. Hirsch (1988) treats multiple products differently than Shank and Churchill (1977) and offers an alternative formulation for analyzing market share and market size variances. This paper compares the two variance formulations and demonstrates that the market share and market size variances under the Hirsch formulation more realistically reflect changes in market share and market size. As a result, the variances under the Hirsch formulation are more useful for managerial decision-making.     

Changes in Factor Betas and Risk Premiums Over Varying Market Conditions

We show risk exposures and premiums associated with the Chen, Roll, and Ross (1986) risk factors change over time and depend on stock market and business cycle condition. Findings also indicate that factor risk premiums change sign between January and non-January, especially during bull markets. These findings serve as a caveat for portfolio managers who allocate assets to match desired exposures to key macroeconomic risk factors.

U.S. Airways merger: A strategic variance analysis of changes in post-merger performance

This case provides students the opportunity to apply strategic variance analysis (SVA) methodology in analyzing the performance changes realized in an airline merger. The U.S. Airways–America West merger provides an example of a complex, strategic action that simultaneously impacts firm size, unit pricing and costs, efficiency, and capacity for the combining airlines. This merger provides a rich example for the analysis since it combines U.S. Airways, a higher cost network airline that is geographically focused on the Eastern U.S., with America West, a low cost airline operating primarily along the Western U.S. The case includes merger and acquisition (M&A) theory discussing market power vs. efficiency motives for mergers and discusses the role of the U.S. Department of Justice and Federal Trade Commission in evaluating M&As and their impact on markets. The case asks students to serve as consultants applying the SVA methodology to the past U.S. Airways–America West merger and provide conclusions.     

Does adoption of ISO 56002-2019 and green innovation reporting enhance the firm sustainable development goal performance? An emerging paradigm

Reporting is a means of communication for companies to their respective stakeholders. The literature on non-financial reporting has mostly focused on operational, Carbon Discloser Project (CDP), and environmental disclosure to firm performance. This reporting and disclosure approach adopted by companies in their sustainability practices appears to be a normative approach. However, there has been a growing demand by stakeholders to incorporate proactive approach in business activities. To meet that, green innovation practices (GIPs) has been integrated as a new element in environmental reporting, thereby reflecting the proactiveness of companies in their adoption of green innovation reporting (GIR). The objective of this study is to advocate for greater disclosure on sustainability reporting by incorporating the GIPs of companies and substantial, sustainable development goal contribution, along with the moderation of the newly upgraded ISO 56002-2019 innovation management system. Adoption of green innovation reporting and ISO 56002-2019 will enhance the level of transparency of business activities and create greater stakeholder confidence along with enhancing the firm's sustainable development of goal performance. Furthermore, an extensive literature review was undertaken to create a GIR framework (i.e., product, process, service and technology) for firms to integrate GIPs into sustainability reporting. The conceptual model proposed the adoption of green innovation reporting and ISO 56002-2019 innovation management system to firm sustainable development goal. This needs to be injected into the sustainable reporting of companies to reflect their innovativeness, actual sustainable business practices and sustainable development goal performance for the firm.     

The role of training in reducing poverty: the case of agricultural workers receiving microcredit in Bangladesh

The policy of providing microcredit and skill training to poor agricultural workers in developing countries is well‐established. In this study, an attempt has been made to assess the effectiveness of the training part of that policy. BRAC (formerly the Bangladesh Rural Advancement Committee), the largest non‐governmental organization in Bangladesh, is making efforts to alleviate poverty by providing microcredit and relevant training to landless and marginal borrowers, who have less than 1.5 acres of land, in order to enhance their standard of living. The study aims to assess the effects of BRAC's training programs on the recipients' total household expenditure. Primary data were collected from female borrowers who participated in the microcredit programs of BRAC and these data reflect the key role women play in agricultural work and the lack of research on their status. The study shows that the training provided to the borrowers failed to create any significant impact on their household expenditure because only a small percentage of borrowers received training and the duration of the training was limited (on average three days per person). Moreover, many of those who received training experienced only a modest income effect. The findings are important not just for the practical purpose of influencing policies for reducing poverty in Bangladesh but also for their contribution to the understanding of the effectiveness of training. The existing literature is concerned mainly with the effectiveness of training in the context of business and other organizations in developed countries. Research on the effectiveness of training in developing countries, particularly in alleviating poverty, is less evident. Moreover, the present research is also exceptional as it focuses only on female trainees.     

Performance of Enhanced Index and Quantitative Equity Funds

We examine the performance of enhanced index and quantitative equity funds. Both types of funds use quantitative models in investment selection. Enhanced index funds set an explicit objective to outperform a benchmark index. Proponents of quantitative funds argue that their management style takes human emotions out of the investment decision‐making process and leads to more objective stock selection. We find evidence of outperformance by quantitatively managed growth funds, especially those investing in small cap stocks.     

The future of Muslim politics : Critique of the ‘fundamentalist’ theory of the Islamic state

This article considers the future of Muslim political thought in the context of growing de-Islamization and the dominance of Western institutions. The ‘fundamentalist’ theory of the Islamic state—total mobilization of Muslim societies under a universal state—is criticized as religiously an immanentist heresy, and politically a totalitarian nightmare. Proposed here is a way out of the moral and intellectual crisis in Islamic political thought through the principle of Shura—meaning that Muslims must evolve their own form of representative government.
