Prices vs. Quantities: The Irrelevance of Irreversibility*

We explore the efficacy of price and quantity controls in a dynamic setup in which the decisions of some agents are irreversible. The assumption of irreversibility is shown to improve the performance of a tax relative to that of a system of tradable quotas and significantly alter the equilibrium behavior of agents. We nevertheless conclude that taking into account the fact that agents’ decisions may be irreversible does not lead to policy implications significantly different from those reached in a simpler model in which irreversibility is ignored.     

The purchasing market entry process—A study of 10 Swedish industrial small and medium-sized enterprises

While an area of importance and concern to managers, international purchasing remains an under researched phenomenon, especially in the context of small and medium-sized firms. Therefore, this article presents a study of the international purchasing market entry processes of 10 industrial SMEs. The findings indicate that managers of SMEs are often reluctant to source abroad. Purchasing markets entries are generally more reactive than proactive, occurring as a consequence of needs for certain products that cannot be found domestically, high domestic costs, unsolicited opportunities and pressures from owners and customers. Nearby purchasing markets typically dominate throughout the process unless cost savings motivate firms to explore more remote markets.     

The relationship between domestic and outward foreign direct investment: The role of industry-specific effects

Previous research has been inconclusive as regards the effect of outward foreign direct investment (FDI) on domestic investments. In this article, we show that this inconclusiveness can be explained at a disaggregated level as a function of the way industries are organized. Based on a simple theoretical framework including monitoring and trade costs, we argue that a complementary relationship can be expected to prevail in vertically integrated industries, whereas a substitutionary relationship can be expected in horizontally organized production. The empirical analysis confirms a significant difference between the two categories of industry as regards the impact of outward FDI on domestic investment. The results may thus have profound policy implications. JEL no. F12, F21, F23, G34.     

Internet service provision and content services: paid peering and competition between internet providers

We consider the relationship of Internet service providers (ISP) and content service providers (CP) in the Internet ecosystem. Currently, the position of ISPs is challenged by the emergence of powerful content service providers, especially with the spreading of bandwidth-demanding video services. The further investment in the network capacity may be hindered by prevailing business models that largely exclude the ISPs from sharing in the major cash flows resulting from content provision. We develop modeling tools for evaluation of business models of ISPs and present results of an analysis of two models with the potential for the generation of additional cash flows for ISP: paid content peering and service differentiation. Firstly, we show that under certain conditions on the cost structure and the level of demand elasticity and uncertainty, it can be profitable for a powerful content provider to resort to paid content peering, thus transferring to the ISP a part of his content provision revenue. The resulting business model may provide substantial benefits to all major participants in this ecosystem: network providers, content and service providers and end users. After this we consider competition in the Internet provision sector and show that - also in this case - the paid content peering can help ISPs to expand the network capacity and at the same time increase profits of content providers. The end users benefit from the lower prices for content services. Finally, we consider the situation when an ISP differentiates the service offer by engaging in content provision, thus entering in direct competition with content providers.     

Using local injury surveillance for community-based injury prevention: an analysis of scandinavian WHO safe community and canadian safe community foundation programmes

Injury surveillance is widely recognized as a critical prerequisite for effective injury prevention, yet few studies have investigated its use by community-based injury prevention programmes. This study examined the extent to which local injury data were collected, documented, analysed, linked to injury prevention action and used for evaluation among WHO Safe Communities in Scandinavia (25 programmes) and the Canadian Safe Community Foundation (SCF) network (16 programmes). For each programme, a key informant with relevant local knowledge was selected to respond to an emailed questionnaire. The study demonstrates that community-based injury prevention programmes experience difficulties accessing and effectively utilizing local injury surveillance data. The findings suggest that the responding SCF programmes approach injury prevention more scientifically than the Scandinavian WHO-designated Safe Community programmes, by making greater use of injury surveillance for assessment, integration into prevention strategies and measures, and evaluation. Despite study limitations, such as the low response rate among Canadian programmes and a large number of non-responses to two questions, the results highlight the importance of, and need for, greater use of local injury surveillance.     

CEO contract design: How do strong principals do it?

We study changes in chief executive officer (CEO) contracts when firms transition from public ownership with dispersed owners to private ownership with strong principals in the form of private equity sponsors. The most significant changes are that a significant portion of equity grants performance-vests based on prespecified measures and that unvested equity is forfeited by fired CEOs. Private equity sponsors do not reduce base salaries, bonuses, and perks, but redesign contracts away from qualitative measures. They use some subjective performance evaluation, do not use indexed or premium options, and do not condition vesting on relative industry performance. We compare the contracts to predictions from contracting theories, and relate our results to discussions of executive compensation reform.
