This article reviews the rapidly growing literature on structural models of complementary choices. It discusses recent modeling developments and identifies promising areas for future research.     

Perverse Audit Culture and Accountability of the Modern Public University

The audit culture which has developed in public universities has led to counter‐productive outcomes. Managerial oversight of academic work has reached a critical tipping point. Extensive auditing of research output by means of performance management assessment regimes motivated by a New Public Management mentality has damaged individual scholarship and threatened academic freedom. Such assessment regimes are perverse and conducive to the development of psychotic tendencies by universities. It is important to understand the effects of a perverse audit culture when re‐thinking and reforming approaches to university performance management. We suggest ways for public universities to acknowledge the need for accountability while remaining true to core academic purposes.     

NAFTA as a Means of Raising Rivals' Costs

The North American Free Trade Agreement (NAFTA) was designed to reduce tariff rates between Mexico, Canada and the U.S.A. over a period of ten years. However, lower tariff rates are only available to firms that comply with complicated and costly NAFTA filing regulations. Such regulations raise costs of small firms relative to large firms in a domestic industry which engages in trade between NAFTA countries. This implication of NAFTA regulations can lead to increased concentration in domestic industries, an hypothesis which can be tested as the transition period comes to an end. Finally, our model suggests an explanation for why the levels of trade from the U.S.A. to Mexico have been lower than general expectations.

Exploring Top Management Language for Signals of Possible Deception: The Words of Satyam’s Chair Ramalinga Raju

This paper explores the potential for systematic scrutiny of the language of top management to reveal signals of possible deceptive conduct. The language used in letters signed by Ramalinga Raju, Chair of the Indian multi-national company Satyam, are analysed using a multi-method quantitative approach. We explore the language in Raju’s annual report letters from 2002–2003 to 2007–2008; and in his letter of January 7, 2009 in which he confessed to deceptive conduct. We analyse the frequency of personal pronouns, the tone of positivity or negativity, the frequency of words of extreme emotion and aspects of the characteristics of language use indicated by the DICTION 5.0 text analysis master variable, CERTAINTY. The text of Raju’s letters appears to have been influenced by his self-confessed deceptive behaviour. Raju’s word choice changed noticeably in his five annual report letters prior to the collapse of Satyam as the scale and impact of his financial misstatements increased. The methods presented should be considered for adoption by auditors and regulators—as a way of assessing whether signals emerging from language use warrant closer (including audit) scrutiny of a firm’s financial reporting and governance. They should also be considered for use by monitors of entity risk, such as credit rating agencies and financial analysts.     

Intangible assets and value relevance: Evidence from the Portuguese stock exchange

We assess the value relevance of the amounts for identifiable intangible assets and goodwill reported in the financial statements of all non-finance companies listed on the main market of the Portuguese Stock Exchange from 1998 to 2008. Additionally, we use panel data to explore the impact on value relevance of Portugal’s formal adoption of International Accounting Standards [IAS] and International Financial Reporting Standards [IFRS] in 2005. A distinctive feature of the accounting by our sample companies is that when they adopted IAS 38 and IFRS 3 in 2005, they were no longer required to recognise some intangible assets (such as start-up costs and research expenditures) and were no longer required to amortise goodwill.We find that net earnings, reported goodwill and other intangible assets are highly significantly associated with stock price. However, whereas earnings are related positively to stock prices when Portuguese Generally Accepted Accounting Principles (GAAP) were applied prior to 2005, the value relevance of earnings appears to have declined after the adoption of IAS/IFRS in 2005. Although the change to IAS/IFRS had no impact on the value relevance of identifiable intangibles as a whole, the evidence suggests that there was a positive effect on the value relevance of goodwill. When the subclasses of identifiable intangible assets are considered, we found evidence of an increase in value relevance of goodwill, other intangible assets, and research and development expenditures.     

How to Become Central in an Informal Social Network: An Investigation of the Antecedents to Network Centrality in an Environmental SCM Initiative

Environmental supply chain management (SCM) initiatives often evolve as informal, grassroots efforts that are driven by policy entrepreneurs at lower management levels in an organization. These individuals usually are not in positions of power or authority to convince others to support the initiative. They thus rely on central positions in informal networks to gain access to and influence over other employees to be better able to sell these initiatives. This study examines how individuals arrive at positions of centrality within the networks surrounding environmental SCM initiatives. Linking social network theory and social capital theory with findings from the organizational behavior and environmental arena, the study investigates how an individual's proactive personality and commitment profile—affective, normative, and continuance commitment—might affect network centrality through the mediating role of championing behavior. Investigating the implementation of an environmental SCM initiative at a multinational enterprise, the authors identified a 90‐actor social network surrounding the initiative. The results provide evidence that championing behavior fully mediates the relationship between commitment and network centrality and to a lesser extent between proactive personality and network centrality. These findings suggest that championing behavior can enable an actor to become more central in social networks. Further, the results indicate that in an environmental SCM context, engendering the right type of commitment is a much more important driver of championing behavior than the proactive personalities of individual actors. This finding suggests that even employees who do not have proactive personalities can champion environmental initiatives and become central within the informal networks that surround these initiatives, if they strongly desire to support the initiative and believe that the initiative will lead to positive change.     

Determinants of Corporate Diversification: Evidence From the Property–Liability Insurance Industry

This article analyzes variations in line‐of‐business diversification status and extent among property–liability insurers. Our results show that the extent of diversification is not driven by risk pooling considerations; insurers operating in more volatile business lines do not diversify more. Diversification can rather be explained by the benefits of internal capital markets and barriers to business growth like market size and concentration. In our analysis, we distinguish between related and unrelated diversification. Using a measure of unrelated line‐of‐business diversification we find the first support for the diversification prediction of the managerial discretion hypothesis that mutual insurers should be less diversified than stock insurers. While mutual insurers tend to exhibit higher levels of total diversification, they engage in significantly less unrelated diversification than do stock insurers.     

URBANIZATION,HEALTH AND HUMAN STATURE

Economic growth has not always generated improvements in a population's health. Biological indicators of human well‐being, including stature, suggest the march to prosperity was not a steady one, and these biological indicators offer estimates of the health costs associated with modern economic growth. We employ an international data set to study the socioeconomic benefits and health costs associated with the transition to modern economic growth during the nineteenth century. We find that while the growth of GDP per capita had a positive impact on the stature of Western populations, prior to the mastery of the germ theory of disease, urbanization had a strong negative impact.
