Intermarket network externalities and competition: An application to the media industry

Intermarket network externalities occur when the utility of a good produced in a given industry varies with the size of the demand for a good produced in another. A particularly significant example of this phenomenon is provided by the interaction between the media and advertising industries. Media consumers vary according to their willingness to pay for a media good, which depends on the advertising volume. In the advertising market, advertisers vary according to their willingness to pay for an advertisement, which also depends positively on the audience reached. We model a situation of competition between two content providers who are rivals in both the media and advertising industries, choosing simultaneously the newspaper prices and the advertising rates. We characterize the equilibria of the game and explore how they depend on audience attitudes towards advertising. Our main finding is that two-sided interactions may induce exit by one of the media companies from either only the advertising market or both markets.     

The Effect of Wal-Mart Supercenters on Grocery Prices in New England

The competitive price effect of Wal-Mart Supercenters on national brand and private label grocery prices in New England is examined. We use primary price data collected on several identical products from six Supercenters in Massachusetts, Connecticut, and Rhode Island and from conventional supermarkets. Taking into account demographics, store characteristics, and market conditions, we show that Wal-Mart decreases prices by 6 to 7% for national brand goods and by 3 to 8% for private label goods. Price decreases are most significant in the dry grocery and dairy departments. Moreover, Wal-Mart sets grocery prices significantly lower than its competitors.     

Do incentive systems spur work motivation of inventors in high tech firms? A group-based perspective

In this paper, we explore with a model the potential tensions between the incentive system of groups of inventors and knowledge diversity in a high tech firm. We show that, when all groups are rewarded and able to interact freely with their peers, extrinsic and intrinsic motives are mutually self-reinforcing, leading to crowding in effects. As a result, the level of created knowledge increases in each group, reinforcing the diversity of the firm’s knowledge base. By contrast, competitive rewards and constrained autonomy are likely to produce motivating effects in a small number of groups, limiting knowledge creation to the firm’s core competencies. In this case, the firm can suffer from crowding out effects by the other groups, leading eventually to the extinction of creation in their fields and reduced diversity in the long run. The results are illustrated with empirical findings from a case study of a French high tech firm.     

Collaborative Resource Solutions

Collaborative Resources Solutions (CRS) is based on a real situation outlining the issues related to buying a service organization. This instructional case requires students to provide advice to a client who is considering purchasing a 50 percent ownership of a similar consulting business with the vision of blending the two companies together and increasing the knowledge base of her current company; therefore improving the ability to target more to clients. The case requires the students to evaluate the strategic, valuation, and financial issues in considering the acquisition of the existing business. In order to do so, students are required to analyze the financial information provided, both historical and forecasted, as well as analyzing key internal operations issues that may impact the future success of the business. This case is suitable for use in upper‐level undergraduate business strategy courses and accounting courses, as well as in master‐level accounting courses. Assessment rubrics and teaching notes accompany the case for use by instructors.     

A longitudinal content analysis of gender role portrayal in Belgian television advertising

This study explores gender role portrayal in advertisements broadcasted on Belgian commercial television. We gathered a sample of 493 commercials (featuring 907 characters) randomly selected out of two periods (January 2002–April 2003, n = 250 and January 2009–April 2010, n = 243) from a database containing all advertisements broadcasted on Belgian commercial television. A content analysis was carried out using a coding scheme based on existing literature. Content categories included gender of the characters, gender roles (i.e. parental, housekeeping and professional expert) and sexual objectification. Hypotheses predicted that men and women would be represented differently in television advertising, and that these differences would reflect traditional gender stereotypes. Moreover, due to regulatory changes, we hypothesize that these differences should decrease over time. Results are largely in accordance with the existing literature. Women tend to be depicted as younger and are portrayed more often within dependent roles as caregiving parent, housewife or as sexual objects than men. A longitudinal analysis of role portrayal changes across two periods within and between genders indicates little change in gender role portrayals in Belgian television advertising between 2002–2003 and 2009–2010. Despite social and regulatory changes, gender stereotypes in advertising seem to persist over time.     

Group and individual risk preferences: A lottery-choice experiment with self-employed and salaried workers

This paper focuses on decision making under risk, comparing group and individual risk preferences in a lottery-choice experiment. In the individual treatment, subjects make choices individually; in the group treatment, each subject placed in a group made lottery choice via voting. In the choice treatment, subjects choose whether to be on their own or in a group. The originality of this research lies in the fact that we introduced variability in socio-demographic characteristics by recruiting salaried and self-employed workers. Our main findings indicate that groups are more likely than individuals to choose safe lotteries. Our results also show that individuals risk attitude is correlated with both the type and the sector of employment.     

Institutional pressures and international market orientation in SMEs: Insights from the French wine industry

In this research, we examine how external institutional pressures influence international market orientation (IMO) in small-medium sized enterprises (SMEs). We use institutional theory and insights from the international entrepreneurship literature to predict how different formal regulative pressures (from national and international sources) as well as different informal normative pressures (from distributors and end-consumers) influence IMO in SMEs. We test our hypotheses using survey data from 107 small wineries across all of the main wine-producing regions in France. The results provide support to the central assertion that it is outside pressures on decision-making – rather than an endowment of internal resources and capabilities – that influence IMO in SMEs. External regulative sources have the strongest effects with pressures on decision-making from national laws having a negative impact on IMO and those from international laws having a positive impact on IMO. We find partial support for the effect of normative pressures from distributors and end-consumers. Implications for theory and management of internationalization in small firms are discussed.     

What Lies beneath? A Sub-National Look at Okun’s Law in the United States

We find that Okun’s Law holds quite well for most U.S. states but the Okun coefficient—the responsiveness of unemployment to output—varies substantially across states. We are able to explain a significant part of this cross-state heterogeneity on the basis of the state’s industrial structure. Our results have implications for the design of state and federal policies and may also be able to explain why Okun’s Law at the national level has remained quite stable over time despite an enormous shift in the structure of the U.S. economy from manufacturing to services.
