Empirical scholarship on the standards-trade relationship has been held up due to methodological challenges: measurement, varied effects, and endogeneity. Considering the trade-effects of one particular standard (ISO 9000), we surmount methodological challenges by measuring standardization via national penetration of ISO 9000, allowing standardization to manifest via multiple (quality-signaling, information/compliance-cost, and common-language) channels, and using instrumental variable, multilateral resistance and panel data techniques to overcome endogeneity. We find evidence of common-language and quality-signaling augmenting country-pair trade. Yet, ISO-rich nations (most notably European) benefit the most from standardization, while ISO-poor nations find ISO 9000 to represent a trade barrier due to compliance-cost effects.

Equipment manufacturers offer different types of maintenance service plans (MSPs) that delineate payment structures between equipment operators and maintenance service providers. These MSPs allocate risks differently and thus induce different kinds of incentives. A fundamental question, therefore, is how such structures impact service performance and the service chain value. We answer empirically this question. Our study is based on a unique panel data covering the sales and service records of over 700 diagnostic medical body scanners. By exploiting the presence of a standard warranty period, we overcome the key challenge of isolating the incentive effects of MSPs on service performance from the confounding effects of adverse selection. We found that moving an operator from a basic pay-per-service plan to a fixed-fee full-protection plan leads to both a reduction in reliability and an increase in service costs. We further show that the increase in cost is driven by both the operator and the service provider. Our results point to the presence of losses in service chain value in the maintenance of medical equipment, and provide the first evidence that a basic pay-per-service plan, where the risk of equipment failure is borne by the operator, can actually improve performance and costs.

This paper uses a rich survey of 6446 households in Slovakia to estimate price elasticities of demand for Internet access, and draw implications for market definition. We estimate a mixed logit model, in which households choose between different broadband technologies: DSL, cable modem, fibre, WiFi and mobile. We find that a number of household characteristics influence the technology choices, and there is also significant unobserved heterogeneity. Demand for Internet access is highly price sensitive. The price elasticity of demand for DSL is −3.02, which falls in the middle of the range of elasticities for the other technologies. Furthermore, the price elasticity of demand at the level of all fixed broadband technologies (DSL + cable modem + fibre + WiFi) is equal to −1.98. For a reasonable range of profit margins, this estimate implies that mobile broadband should be included in the relevant antitrust market of fixed broadband. Our findings have implications for competition policy in Central and Eastern European countries where due to poor copper networks mobile broadband is an important alternative to fixed broadband.

This paper draws attention to a new dimension of organization, the semiformal organization, and it reveals how the allocation of different membership forms can render knowledge-intensive organizations more flexible and exploratory in their knowledge creation efforts without sacrificing the functions stably enacted via the formal organization. Most knowledge-intensive organizations seek to create new spaces for collaborations through formally prescribed departments and divisions or through serendipitous, emergent, informal associations (i.e., the formal and informal organization). However, organizations also strategically manage what we call the “semiformal organization” to guide the creation of new work relations and encourage innovation. These secondary memberships are organizationally sponsored and directly related to the organizations’ core research functions, but they are voluntarily joined. As such, they are distinct from formal and informal memberships. On the basis of extensive longitudinal analyses of research initiatives at Stanford University, we find that the semiformal organization provides a compelling channel through which organizations can shape employees’ collaborations and overall productivity.

Launched in early 2005, Zopa is a peer-to-peer online brokerage that couples British residents who want to lend with those who want to borrow. The company represents a new business model in the retail financial services industry, and since Zopa is not technically a bank and does not lend money itself, the capital requirements to run the business are relatively small. Compared to a traditional full service bank Zopa concentrates on only a few steps of the value chain. This case study provides an overview of how Zopa, a value innovator, has developed a unique position in the market through an innovative business model. This case enables students to develop a good understanding of the elements of a value innovation and how technologies have the potential to shake up an established industry structure and its key players. Students also get to discuss the sustainability of competitive advantage in a business in which network effects play an important role. Finally, the case can be used to address the topic of how incumbent firms should respond to innovative new business models.

The case helps students to develop a deeper understanding of the concepts of positioning, value innovation, sustainable competitive advantage, and responding to new market entrants. It is intended for MBA courses in strategic management, innovation, and marketing and can also be used in executive education programs as part of a competitive strategy program to discuss issues related to positioning, value innovation, and sustainable competitive advantage. The case is especially suitable for financial services managers in traditional retail or online banking facing the threat of market entry by low-cost or more focused firms.
