We report an experimental study that aims to elicit monetary measures of strength of preference in choices involving pairs of risky prospects. Despite extensive testing to refine the instruments used, we find that these money measures are systematically biased upwards relative to subsequent binary choices. We discuss possible reasons for this bias and its broader implications. 相似文献

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. 相似文献

The intensified use of hydropower plays a substantial role in the Austrian energy sector. There are indeed plans to open up the remaining potentials, especially in the field of small-scale hydropower. However, hydropower creates multiple impacts. Although investments in hydropower are undisputed due to security of supply issues, climate change and dependency concerns, the technology is subject to some disadvantages. Hydropower plants are often seen as a blot on the landscape and a threat for the ecosystem, especially for fish and other water-dependent wildlife. Accordingly, hydropower plants are principally in conflict with nature conservation as for instance the European Water Framework Directive. With the help of a discrete choice model the trade-off between economic and climate-related advantages and the negative environmental side effects of new hydropower schemes was identified and quantified. While people value the economic (employment effects) and environmental (reduced air emissions) benefits related to the generation of electricity from hydroelectric power, they wish to be compensated for the loss of nature and landscape new hydropower plants are associated with. Moreover, confirmation of the “Not in my backyard” phenomenon was found, meaning that people generally prefer the construction of new hydropower stations, but not close to their homes. 相似文献

We consider multiple-principal multiple-agent models of moral hazard: principals compete through mechanisms in the presence of agents who take unobservable actions. In this context, we provide a rationale for restricting principals to make use of simple mechanisms, which correspond to direct mechanisms in the standard framework of Myerson (J Math Econ 10:67–81, 1982). Our results complement those of Han (J Econ Theory 137(1):610–626, 2007) who analyzes a complete information setting where agents’ actions are fully contractible. 相似文献

We present a new, global database on tourist destinations. The database differs from other databases in that it includes both domestic and international tourists; and it contains, for the most important destinations, data at national level as well as at lower administrative levels. Missing observations are interpolated using statistical models. The data are freely accessible on the internet. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

The paper presents different theoretical perspectives on the issue of business networks and their role in the process of internationalization. With regard to methodology, a specific case study is conducted of a vertically integrated firm in the fashion supply chain, which has implemented branding and retailing strategies in international markets. The case analysis, which is the result of a longitudinal study conducted over several years, aims at an in depth analysis of the extent to which business relationships represent a learning context involving opportunities/constraints in the internationalization process. The paper outlines the relationship between the specific business model, the international patterns followed, and business relationships. Three research questions are posed and discussed. Some final remarks on the relationships between business networks and international retail expansion conclude the work. 相似文献

Effective knowledge management is important to the success of information technology projects. This research applies the integrated lens of the absorptive capacity theory and the social process model of information system development projects to examine the dynamic of knowledge activities concerning broadband infrastructure development in the context of municipal broadband networks. The research questions are: (1) What is the extent of the dynamic of knowledge activities involved in the development process?, (2) What are the events that trigger knowledge activities in municipal broadband development?, and (3) How does a city create and utilize new knowledge in the development process? This study examines municipal wireless projects in three cities (Chaska, MN; Hermosa Beach, CA; and Fredericton, Canada). Events that trigger knowledge activities are assignment of personnel, physical system construction, performance problems, resistance, and reassignment of organizational roles. Four factors that influence knowledge activities and project performance are the dynamic of technology development, partnership commitments, limitation of external knowledge and learning-by-doing, and political dynamics. The study has policy implications for cities that are in the process of planning and deployment. A good project planning, user expectation management, systematic performance evaluation, a careful partner selection process, and the use of service level agreements are important to project success. In addition, cities need to take into consideration that the technology is not a plug and play technology and that considerable efforts are needed to integrate the technology with other solutions to deliver broadband services as well as to configure the system according to topologies, street conditions, buildings, density of trees, among others. 相似文献

El Niño Southern Oscillation (ENSO) is a naturally occurring phenomenon that affects weather around the world. Past ENSO episodes have had severe impacts on the economy of Colombia. We study the influence of ENSO on Colombian coffee production, exports, and price. Our structural econometric specification is consistent with an economic model of the market for Colombian coffee which, in the short run, is characterized by a downward‐sloping demand curve and by a vertical supply curve. We show that El Niño (i.e., positive shocks to ENSO) is beneficial for Colombian production and exports and decreases the real price of Colombian coffee. On the contrary, La Niña (i.e., negative shocks to ENSO) depresses Colombian coffee production and exports and increases price. However, the overall impact of ENSO shocks is small. Both in the short run and in the long run, shocks to international demand for Colombian coffee are more relevant than supply‐side shocks in Colombia in explaining the dynamics of the price of Colombian coffee. Our results suggest that a given coffee price shock can have beneficial, detrimental, or negligible effects on the Colombian economy, depending on its underlying cause. As a consequence, policy responses to coffee price shocks should be designed by looking at the causes of the shocks. 相似文献

Conservation Agriculture (CA) has been widely promoted in sub-Saharan Africa (SSA) as a sustainable agricultural practice, yet with debatable success. Most authors assume successful adoption, only if all three principles of CA are implemented: (1) minimum or zero tillage, (2) maintenance of a permanent soil cover, and (3) integration of crop rotations. Based on this strict definition, adoption has declined or remained stagnant. Presently, not much attention has been given to context-suited adaptation possibilities, and partial adoption has not been recognized as an entry point to full adoption. Furthermore, isolated success cases have not been analysed sufficiently. By applying the QAToCA approach based on focus group discussions complemented by semi-structured qualitative expert and farmer interviews, we assessed the reasons behind positive CA adaptation and adoption trends in Zambia. Main reasons behind Zambia’s emerging success are (1) a positive institutional influence, (2) a systematic approach towards CA promotion – encouraging a stepwise adaptation and adoption, and (3) mobilization of strong marketing dynamics around CA. These findings could help to eventually adjust or redesign CA promotion activities. We argue for a careful shift from the ‘dogmatic view’ on adoption of CA as a packaged technology, towards adapting its principles to the small-scale farming context of SSA. 相似文献

This paper analyses the main policy issues raised by regulatory reform in air transport in sub‐Saharan Africa. Its basic premise is that improving ait infrastructure is of paramount importance for the region as it tries to integrate more thoroughly into the world economy. On the basis of the experience of OECD countries with privatisation, liberalisation, and regulatory design, the author analyses progress being made in sub‐Saharan Africa and identifies three important case studies: the restructuring of the regional airline of Francophone Western Africa, the sell‐off of the state‐owned airline of Kenya, and the overall reform process in South Africa, by far the largest market in the sub‐continent. The analysis highlights the importance of regional dynamics in the upgrading of the air transport industry in developing and emerging areas. Sub‐Saharan Africa has made smaller progress in this respect than, for instance, Central America. As the start of the Millennium Round and the first WTO air transport review approach, these issues will gain policy priority for all countries, and may become powerful bargaining tools for non‐OECD countries to press for more open access into OECD markets for the South's traditional exports. 相似文献
