ARE DISAGREEMENTS AMONG MALE AND FEMALE ECONOMISTS MARGINAL AT BEST?: A SURVEY OF AEA MEMBERS AND THEIR VIEWS ON ECONOMICS AND ECONOMIC POLICY

The authors survey economists in the United States holding membership in the American Economic Association (AEA) to determine if there are significant differences in views between male and female economists on important policy issues. Controlling for place of current employment (academic institution with graduate program, academic institution—undergraduate only, government, for‐profit institution) and decade of PhD, the authors find many areas in which economists agree. However, important differences exist in the views of male and female economists on issues including the minimum wage, views on labor standards, health insurance, and especially on explanations for the gender wage gap and issues of equal opportunity in the labor market and the economics profession itself. These results lend support to the notion that gender diversity in policy‐making circles may be an important aspect in broadening the menu of public policy choices. (JEL A11, J78, A14)     

ORGANIZATIONAL AND OCCUPATIONAL COMMITMENT: KNOWLEDGE WORKERS IN LARGE CORPORATIONS*

Previous discussion of knowledge work and workers tends to overlook the importance of contextual knowledge in shaping the organizational form of knowledge workers who are employees in large corporations. This paper proposes a model to understand the way knowledge base and organizational form are related to the work commitment, effort and job satisfaction of knowledge workers. The model is derived from (1) a critical examination of the market model of knowledge work organization, and (2) the results of empirical research conducted in two large corporations. We argue that contextual knowledge is important in the relationships between the corporation and knowledge workers. A dualistic model and an enclave organizational form are suggested to examine the relationships between the commitment, work effort and job satisfaction of knowledge workers. We noted from our empirical cases that enclave‐like work teams enhanced the expertise and job autonomy of knowledge workers vis‐à‐vis management. These work teams together with the performance‐based pay system, however, led to unmet job expectations including limited employee influence over decision‐making and careers, and communication gaps with senior management. Under these circumstances, and in contrast to the impact of occupational commitment, organizational commitment did not contribute to work effort. The study highlights the importance of management’s strategy in shaping the organizational form of knowledge work. The paper concludes by noting general implications of our study for the management of expertise and for further research.     

Optimal employment contracts and the returns to monitoring in a principal-agent context

Abstract. In this paper we study a two-person firm consisting of a principal and an agent. The principal hires the agent to provide some input into the production process. The output of the production process is determined by the agent's input and an exogenous state realization. Subsequent to joining the firm, but prior to choosing his input, the agent privately observes the state realization. The principal employs an imperfect monitoring system that publicly reports on the state realization. Our purpose in studying this model is to better understand the effects of monitoring on the design of the optimal employment contract and the determinants of the value of monitoring in a model with asymmetric information. Résumé. Les auteurs étudient une entreprise constituée de deux personnes, un mandant et un mandataire. Le mandant embauche le mandataire pour sa contribution au processus de fabrication. Le résultat du processus de fabrication est déterminé par la contribution du mandataire et par la réalisation d'un état exogène. Après s'être joint à l'entreprise, mais avant de déterminer quelle sera sa contribution, le mandataire observe, en privé, la réalisation de cet état exogène. Le mandant a recours à un système de suivi imparfait qui fait le point, à l'intention du public, sur la réalisation de l'état en question. L'étude de ce modèle permet une meilleure compréhension des conséquences du suivi sur la nature de contrat d'emploi optimal et des déterminants de la valeur du suivi dans un modèle caractérisé par une information asymétrique.     

Do Managerial Motives Influence Firm Risk Reduction Strategies?

This article finds evidence consistent with the hypothesis that managers consider personal risk when making decisions that affect firm risk. I find that Chief Executive Officers (CEOs) with more personal wealth vested in firm equity tend to diversify. CEOs who are specialists at the existing technology tend to buy similar technologies. When specialists have many years vested, they tend to diversify, however. Poor performance in the existing lines of business is associated with movements into new lines of business.     

The Value of Investment Banking Relationships: Evidence from the Collapse of Lehman Brothers

We examine the long‐standing question of whether firms derive value from investment bank relationships by studying how the Lehman collapse affected industrial firms that received underwriting, advisory, analyst, and market‐making services from Lehman. Equity underwriting clients experienced an abnormal return of around ?5%, on average, in the 7 days surrounding Lehman's bankruptcy, amounting to $23 billion in aggregate risk‐adjusted losses. Losses were especially severe for companies that had stronger and broader security underwriting relationships with Lehman or were smaller, younger, and more financially constrained. Other client groups were not adversely affected.     

Promises,Promises: How Consumers Respond to Warranties in Internet Retailing

Past studies have shown that perceived risk is a critical determinant of purchase intention in non–store retailing contexts, including Internet retailing. Extant literature in physical retailing suggests that warranties can be a significant variable in reducing consumers’ perceived risk. We examine the role of Web site warranties in risk reduction and how warranty information interacts with retailer reputation and brand name as two other risk relievers in an online shopping environment. Results suggest that warranties can make a positive difference for online retailers with strong reputations with respect to perceived risk, perceived product quality, and purchase intentions. However, consumers are less influenced by warranty information when dealing with online retailers with weak reputations. For the other extrinsic cue, however, we find that warranty information does not have an effect when dealing with brand names, suggesting that a brand name’s impact on online risk reduction remains regardless of the presence of warranty information.     

ESTIMATING THE IMPACT OF BEER PRICES ON THE INCIDENCE OF SEXUALLY TRANSMITTED DISEASES: CROSS‐PROVINCE AND TIME SERIES EVIDENCE FROM CANADA

We attempt to contribute to the literature by evaluating the effects of higher beer prices on gonorrhea and chlamydia rates through pooling data across Canadian provinces and over time. Ordinary least squares as well as instrumental variables estimates suggest that higher real beer prices are correlated with a reduction in both gonorrhea and chlamydia rates, with corresponding implied elasticities within a tightly defined interval of (roughly) ?0.7 to ?0.9. However, the increase in real beer prices over the sample period is only responsible for less than a tenth of the decline in gonorrhea rates. (JEL I18)     

Disclosures Exposed: Banner Ad Disclosure Adherence to FTC Guidance in the Top 100 U.S. Web Sites

With banner ads accounting for one‐fifth of the $16.4 billion spent on Internet advertising in 2006, this advertising format has become an integral marketing communications tool. Inclusion of required disclosure language and presenting those disclosures in a clear and conspicuous manner are important areas of regulatory interest and in recent years have extended to the online environment. This study examines the extent to which disclosures in banner ads in the top 100 U.S. Web sites adhere to Federal Trade Commission guidance in these two areas. Additionally, this study compares the banner ad results for clear and conspicuous presentation to those of a prior study that examined television advertising. All the banner ads in the study contained at least one disclosure; yet, adherence was mixed in terms of providing all the required information clearly and conspicuously. Implications of these results are discussed.
