When the mirror gets misted up: Modularity and technological change

This study investigates how component technological change affects the relationship between product modularity and organizational modularity (the across‐firm mirroring hypothesis). Studying the air conditioning industry, we show that the across‐firm mirroring hypothesis does not hold for technologically dynamic components and the associated supply relationships. In this case, the mirror gets “misted up” with buyers and suppliers having recourse to information sharing even in the presence of highly modular components. Our study contributes to the debate on the organizational implications of modularity and its ramifications for the theory of the firm. Copyright © 2013 John Wiley & Sons, Ltd.     

Complementing Cournot’s analysis of complements: unidirectional complementarity and mergers

We study the price and welfare effects of a merger of firms producing unidirectional complements: a firm is producing a product (called an optional good) that is valuable only if it is consumed with the other product (called a base good) produced by another firm. Under the assumption that there are two types of consumers: (i) those who consume one unit of the base good only or nothing (having zero valuation of the optional good), and (ii) those who consume one unit of the composite good or nothing, we show that a merger of the two firms raises the price of the base good, resulting in lower consumer surplus for the former consumer group, if and only if the average willingness to pay in the latter consumer group is sufficiently low. This result is in sharp contrast to Cournot’s (Researches into the mathematical principles of the theory of wealth, 1838) classical implication that a merger of firms producing strict complements makes all consumers strictly better off.     

Sorting the good guys from bad: on the optimal audit structure with ex-ante information acquisition

In a costly state verification model under commitment, the principal may acquire a costly public and imperfectly revealing signal before or after contracting. If the project remains profitable after all signal realizations, optimally the signal is collected, if at all, only after contracting, and it may be acquired randomly or deterministically. Moreover, audit is deterministic and targeted on some signal-state combinations. The paper provides a detailed characterization of the optimal contract and performs a comparative static analysis of signal acquisition strategy and payoffs with respect to enforcement costs and informativeness of the signal. We explore the robustness of the results, including commitment issues. The results are interpreted in light of the observed features of financial contracts, showing that the optimality of the standard debt contract with deterministic audit extends to a setting with random audit.     

Getting Cars Off the Road: The Cost-Effectiveness of an Episodic Pollution Control Program

Ground-level ozone remains a serious problem in the United States. Because ozone non-attainment is a summer problem, episodic rather than continuous controls of ozone precursors are possible. We evaluate the costs and emissions reductions of a program that requires people to buy permits to drive on high-ozone days. We estimate the demand function for permits based on a survey of 1,300 households in the Washington, DC, metropolitan area. Assuming that all vehicle owners comply with the scheme, the permit program would reduce nitrogen oxides ( $\text{ NO }_{\mathrm{x}}$ ) by 42 tons per Code Red day at a permit price of $75. Allowing for non-compliance by 15 % of respondents reduces the effectiveness of the scheme to 33 tons of $\text{ NO }_{\mathrm{x}}$ per day. The cost per ozone season of achieving these reductions is approximately $9 million (2008 USD). Although year-round measures, such as the Tier II emissions standards, might be preferred on benefit-cost grounds, an episodic permit system might be considered as an interim measure before the Tier II emissions standards are fully reflected in the vehicle fleet.     

Formal,Justice‐Oriented Voice in the Nonunion Firm: Who Speaks Up and When?

Employee willingness to exercise workplace voice has been the subject of much recent research. However, very different types of voice are observed within the workplace, with some forms of voice receiving limited scholarly attention. In particular, limited attention has been given to the determinants of formal, justice‐oriented voice within a nonunion context. Using a policy‐capturing design, we examine factors that affect decisions to use formal, justice‐oriented voice among 498 nonunion employees who had access to the same appeal procedure. The results suggest that this type of voice is affected by perceptions regarding immunity from negative managerial reactions to voice and also by factors associated with the utility of voice (e.g., the social power of those involved in the appeal and the evidence available to support the appeal). The results further suggest that perceived immunity moderates the impact of the social power of those involved in the appeal and the evidence available.     

A network modeling approach for the optimization of Internet-based advertising strategies and pricing with a quantitative explanation of two paradoxes

This paper addresses the determination and evaluation of optimal Internet marketing strategies when a firm is advertising on multiple websites. An optimization model is constructed for the determination of the optimal amount of click-throughs subject to a budget constraint. The underlying network structure of the problem is then revealed and exploited to obtain both qualitative properties of the solution pattern as well as computational procedures. In addition, three different pricing schemes used in Internet marketing are quantitatively compared and indices that can guide marketers to shift from one scheme to another are proposed. Finally, two numerical examples are constructed that demonstrate two paradoxes: (1) that advertising on more websites may reduce the total responses and (2) that advertising on more websites may reduce the click-through rate. Through the analysis of the network model, such puzzling phenomena are then quantitatively explained.     

Developing indigenous tourism in the bomas: critiquing issues from within the Maasai community in Tanzania

ABSTRACT

With safari attractions dominating the African tourism sector, many tourism studies in Africa have focused on wildlife and wilderness resourced-based tourism, with a secondary body of literature exploring cultural aspects of tourism. Recently many countries in the region, including Tanzania, have started to recognize the potential for stand-alone, culture-based tourism to diversify the tourism industry and for rural, economic development purposes. Drawing upon insights from local stakeholders, primarily members of the Maasai community this study identifies the critical challenges for providing indigenous cultural tourism in the Ngorongoro Conservation Area, Tanzania. Qualitative data for the study were collected through interviews and site visits to eight Maasai bomas (cultural tourism villages or settlements). Thematic analysis of the interviews revealed significant limiting factors affecting the development of indigenous cultural tourism amongst Maasai in Tanzania. The findings indicate that achieving success in indigenous cultural tourism is therefore challenging, and needs to incorporate specific community-based strategies which can facilitate the development of Maasai cultural tourism.     

Gender differences in entrepreneurship and intrapreneurship: an empirical analysis

This study examines the gender gap in start-up activities to determine whether it is family status or employment status that is responsible for the observed gender gap. We consider independent entrepreneurship and intrapreneurship as two different start-up modes: While intrapreneurship is conducted within an established organization, independent entrepreneurship is solely an independent activity. This study focuses on this fundamental distinction to identify the parameters of our empirical model. Using nationally representative US data, we find that the effects of being a part-time worker on the likelihood of becoming an independent entrepreneur differ across genders. The obtained results suggest similar findings for intrapreneurship, but in opposite directions. Furthermore, our decomposition results suggest that for both entrepreneurship and intrapreneurship, the gender differences in the employment-related variables are more significant than those in the family-related variables in affecting the observed gender gap negatively (for entrepreneurship) or positively (for intrapreneurship).     

The impact of culture on consumers’ perceptions of service recovery efforts

The increasing globalization of business provides a compelling reason for understanding the cultural context of consumer behavior. The research reported here examines the impact of culture on consumers’ perceptions of service recovery efforts. In particular, we studied in an experimental setting, across East-West cultures, the combined effects of explanation and compensation in shaping customers’ attributions and post-recovery perceptions in a medium contact service—a restaurant setting. Our findings show that the differential sensitivity of East Asian and American consumers to situational constraints influence their attributions for service failures, and thus moderate their satisfaction with service recovery process. More specifically, the results suggest that a causal explanation for service failure decreases the likelihood of US consumers falling prey to the fundamental attribution error. Conversely, among East Asians, an explanation had minimal influence in attributional processes. Finally, our results indicate that attributional processes influence customer perceptions of employee effort, which in turn is linked to post-recovery satisfaction.     

Making direct democracy work: a rational-actor perspective on the <Emphasis Type="Italic">graphe paranomon</Emphasis> in ancient Athens

The specific way the Athenians set up their democracy presents both theoretical and empirical challenges. Decisions were taken by majority vote in the Assembly. To keep politicians in line, the Athenians first used ostracism, which however was replaced by the graphe paranomon around 415 BCE. The latter provided that anybody who had made a proposal in the Assembly could be accused of having made an unconstitutional suggestion, bringing a potentially severe penalty if found guilty. We know of 35 such cases between 403 and 322. During the fourth century the notion of illegality was extended to a mere question of political undesirability. Henceforth any decision by the Assembly could be overturned by the courts, but if the accuser failed to get at least 20% of the jury votes, he was punished instead. While these rules can be seen as a safeguard against bad decisions, they also provided the Athenian politicians with important information about the relative strength of their political support. This effect has not been analysed before, and it may help explain the relative stability of political life in classical Athens. Furthermore this analysis also contributes to our understanding of a curious but often overlooked fact, namely that the decrees of the Athenian Assembly to a great extent concerned honorary rewards, and the use of the graphe paranomon in turn was largely focussed on the honorary decrees.
