Basic Process Capability Indices: An Expository Review

A review of the four basic process capability indices has been made. The interrelationship among these indices has been highlighted. Attention has been drawn to their drawbacks. The relation of these indices to the proportion nonconforming has been dwelt upon and the requirement of the adequate sample size has been emphasized. Cautionary remarks on the use of these indices in the case of nonnormal distributions, skewed distributions, and autocorrelated data are also presented. The effect of measurement error on process capability indices has been dealt with in great detail.     

Drivers of Green Supply Chain in Emerging Economies

In spite of the burgeoning interest in green supply chain management in Western developed countries and large emerging economies, little research exists on the topic in small emerging and developing countries. In this study, we surveyed firms based in Dubai to identify the main drivers of green supply chain management and their impact on supply chain greening. We discuss theoretical and managerial implications of the findings. © 2013 Wiley Periodicals, Inc.     

International Cross‐Listings and Subsequent Security‐Market Choices: Evidence from ADRs

We study the link between the attributes of American depositary receipt (ADR)‐listed firms and their post‐listing security‐market choices. We find that developed market firms are more likely to issue equity and debt than their emerging market counterparts. Furthermore, we find that large firms are more likely to issue debt and less likely to issue equity. When we examine locations where ADR firms raise their capital, we find that firms originating from countries where the protection of minority shareholders is weak are more likely to issue debt on their home markets and less likely to issue debt on international markets (excluding U.S. markets). Furthermore, ADR firms originating from developed (emerging market) countries are more (less) likely to issue their equity on their domestic markets and less (more) likely to issue equity on international markets (excluding U.S. markets).     

The governance of risk management: The importance of directors’ independence and financial knowledge

We test the effects of the independence and financial knowledge of directors on risk management and firm value in the gold mining industry. Our original hand‐collected database on directors’ financial education, accounting background, and financial experience allows us to measure the effect of financial knowledge on risk management activities. We show that directors’ financial knowledge increases firm value through the risk management channel. This effect is strengthened by the independence of the directors on the board and on the audit committee. Extending the dimension of education, we show that, following unexpected shocks to gold prices, firms with financially educated directors are more effective in hedging than average firms in the industry. Firms that hedge more also attracts highly educated directors on their board and audit committee. As a policy implication, our results suggest adding the experience and education dimensions to the 2002 Sarbanes–Oxley Act and New York Stock Exchange requirements for better governance.     

A pattern‐based approach to extract REA value models from business process models

Business models are economic models that describe the rationale of why organizations create and deliver value. These models focus on what organizations offer and why. Business process models capture business activities and the ways in which they are accomplished (i.e. their coordination). They explain who is involved in the activities, and how and when these activities should be performed. This paper discusses the alignment between business models and business process models. It proposes a novel systematic method for extracting a value chain (i.e. business model) expressed in the Resources, Events, Agents (REA) ontology from a business process model expressed in Business Process Model and Notation?. Our contribution is twofold: (1) from a theoretical standpoint we identified a set of structural and behavioural patterns that enable us to infer the corresponding REA value chain; (2) from a pragmatic perspective, our approach can be used to derive useful knowledge about the business process and serve as a starting point for business analysis.     

The choice of ADRs

We study the determinants of a firm’s decision to issue one of the four available ADR programs (Level I, Level II, Level III, and Rule 144A). We find that the firm’s attributes (size, income, asset growth, leverage, privatization, ownership structure, and country-of-origin) and the firm’s home-country institutional variables (accounting rating and legal protection of minority shareholders) condition this choice. We also examine the issuing activity and the determinants of the ADR choice before and after the enactment of the Sarbanes–Oxley (SOX) Act. Following this structural change, we provide evidence of a reallocation between ADR programs. Compared to the pre-SOX period, firms from emerging markets, and those from countries with weak legal protection of minority shareholders, are more likely after SOX to choose Rule 144A and Level III, respectively.     

Can multitasking influence professional scepticism?

Motivated by concerns about the adverse effects of multitasking in audit practice and research that highlights the effects of mindset orientation on professional scepticism, we investigate how the performance of tasks consistent with different mindset orientations affects auditors’ professional scepticism in a subsequent, unrelated task. Results show that auditors who first complete a task that requires concrete (abstract) thinking display greater professional scepticism during a subsequent, unrelated task that involves evaluating a narrow and complete set of evidence (a broad and incomplete set of evidence). We discuss the implications for professional scepticism in multitasking environments.

A robust analysis of the relationship between renewable energy consumption and its main drivers

We provide a comprehensive and robust analysis of the drivers of renewable energy consumption for a panel of 64 countries, using both the static (Pooled OLS, Panel Fixed and Random Effects) and dynamic (difference and system GMM) panel data estimation approaches. We show that the dynamic panel data model provides more efficient estimators than the static ones and that increases in per capita CO₂ emissions and per capita trade with foreign partners mainly drive the changes in per capita renewable energy consumption. We also find limited evidence of oil price effects on renewable energy consumption, which reflects the fact that renewable energy is just a complement and not a perfect substitute of crude oil, at least in the short run.     

Efficiency frontier and matching process on the labour market: Evidence from Tunisia

The purpose of this paper is to study the determinants of the inefficient functioning of the Tunisian labour market. The study takes advantage of the recent development in the stochastic frontier techniques and estimates, the matching function for Tunisia using disaggregated data. We include control variables as determinants of matching efficiency and regional disparities. We confirm that the persistently high rate of unemployment is the result of not only excess labour supply but is also related to a shortfall between supply and demand (sector, location, and qualification).
