We use a simple theoretical model of seasonal market participation in the presence of liquidity constraints and transaction costs to explain the ‘sell low, buy high’ puzzle in which some households do not take advantage of inter‐temporal price arbitrage through storage and sell output postharvest at prices lower than observed prices for purchases in the subsequent lean season. We test our model with data from western Kenya using maximum likelihood estimation of a multivariate sample selection model of market participation. Access to off‐farm income and credit indeed seem to influence crop sales and purchase behaviours in a manner consistent with the hypothesised patterns. 相似文献

The lead user concept has attracted a lot of attention from scholars and practitioners alike. However, different studies apply different conceptualizations and measures of the lead user construct. Such variation in measurement of the construct make it almost impossible to consolidate findings from prior lead user research, which in turn hampers the accumulation of insights on the concept itself. This is also a challenge with respect to managerial practice: due to different interpretations of the concept, managers and R&D staff find it difficult to identify lead users for workshops and cooperation, and companies are often unable to transfer results from lead user projects to new product and business development. As a result, they only rarely repeat their work with lead users. The aim of this article is therefore to provide some thoughts and guidance on the conceptualization and measurement of the lead user construct. 相似文献

We analyse the optimal location choice of a monopolistic firm that operates two arbitrarily located platforms on a two‐sided market. By extending the traditional Hotelling framework, we show that the optimal platform locations are equivalent to the one‐sided benchmark if both sides are either restricted to single‐ or multi‐homing. In the mixed case (one side single‐homes, the other one multi‐homes), the optimal platform locations are in line with the respective symmetric case. If the monopolist is restricted to choosing the same location on either side of the market, the optimal locations are determined by the relative profitability of the market sides. 相似文献

The life‐blood of most organizations is knowledge. Too often, the very mechanisms set up to facilitate knowledge flow militate against it. This is because they are instituted in a top‐down way, they are cumbersome to manage and the bridges of trust fail to get built. In their thirst for innovation, the tendency is for firms to set up elaborate transmission channels and governance systems. As a result, staff are drowned in a deluge of mundane intranet messages and bewildered by matrix structures, while off‐the‐wall ideas and mould‐breaking insights are routinely missed. Added to this is the challenge of operating across professional, cultural, regional and linguistic boundaries, where ways of sharing knowledge differ markedly, even within the same project team. Drawing upon extensive research with scientists in the ATLAS collaboration (a high‐energy particle physics experiment comprising 3,500 scientists from 38 countries), we explore five paradoxes associated with knowledge exchange in global networks. Each paradox leads to a proposition which takes the theory and practice of knowledge management in a fresh direction. We conclude by outlining a number of HRM priorities for international knowledge‐intensive organizations. 相似文献

This paper uses national data on individual physicians and two control groups to provide evidence on the extent to which each of five medical malpractice reforms impacts the decision to move one's medical practice to another state. We find robust evidence that states that have implemented noneconomic damage caps experience less out-migration of physicians than states that do not have these reforms. In addition, we find some evidence that joint and several liability reforms and patient compensation funds also impact the migration decisions of physicians. 相似文献

The concept of ‘Devolution’—the transfer of powers away from the Central Government to more local bodies of Government, has been used across many different areas of policy and by many different national governments. This paper examines the devolution of transport powers to the existing Local Traffic Authorities in England via the 2004 Traffic Management Act. The paper first presents a summary of how several different nations have undertaken this process of devolving transport powers and responsibilities to either new or existing bodies. It then presents research from an electronic survey concerning how English Local Traffic Aut`horities are choosing to use some of the new powers available to them and their opinion on complementary areas of transport policy. Research is also presented from structured telephone interviews, concerning how individual Local Authorities perceive the efficacy and equity of the new legislation. Overall, the results show that only some of these new powers are likely to be used by English Local Authorities, with limited variation in how different types of LTA are choosing to implement these new powers. The structured telephone interviews provided some evidence that rural Authorities in particular are more dissatisfied with the legislation and consider some of the measures unhelpful. The results provide some insights on the formulation of devolved policy applicable to existing Local Government bodies and the varying benefits that can be perceived to apply to different types of Local Authority. Conclusions are drawn on some of the practical difficulties arising from the English experience, and lessons of relevance are drawn for other nations considering a similar devolution of transport powers. 相似文献

Research has called into question the impact of the World Trade Organization (WTO) on trade. This research, however, has been called into question on both modeling grounds for and failing to utilize comprehensive fixed effects. Others have found that when these factors are accounted for, imports rise by significant amounts. This paper seeks to reconcile these findings. I find that the WTO has a larger, though uneven, impact on exports than imports. The results indicate that the WTO frequently causes imports and exports to move in opposite directions negating any increase in overall trade. The regressions with and without fixed country effects generally demonstrate pattern consistency for generalized results that are robust to change. Owing to the finding that imports rise modestly or even fall without country effects while exports rise, the results imply that countries may not be as interested in liberalizing trade as selling to the world. 相似文献

Water conflicts are intensifying as the population grows in the American West. Stakeholders seek a better understanding of households’ water knowledge, preferences, and willingness to pay (WTP) as they contemplate various water allocation initiatives. An Internet survey provides insight into western households’ perceptions and preferences regarding water use and management, their familiarity with water terminology, and their WTP a fee in support of eight potential water initiatives regarding water acquisition, conservation, and reallocation. Further analysis identifies factors that influence the decision. Just over half of all respondents express a WTP the fee, with an estimated median WTP among survey respondents of $15.65 per summer month. Respondents with higher self-reported water knowledge are more likely to support the fee. The probability of supporting the fee is also influenced by respondents’ demographic characteristics and attitudes toward water scarcity and management. Les conflits liés à l’eau s’intensifient à mesure que la population s’accroît dans l’Ouest américain. Les parties prenantes cherchent à découvrir les connaissances sur l’eau, les préférences et le consentement à payer des ménages étant donné qu’elles envisagent divers schémas d’allocation de l’eau. Un sondage en ligne a donné un aperçu des perceptions et des préférences des ménages de l’Ouest américain concernant l’utilisation et la gestion de l’eau, de leur degré de connaissance de la terminologie de l’eau et de leur consentement à payer une taxe pour appuyer huit projets éventuels d’acquisition, de conservation et de réallocation de l’eau. Une analyse plus détaillée a déterminé les facteurs qui influençaient les décisions. Un peu plus de la moitié des répondants ont indiquéêtre prêts à payer une taxe. Chez les répondants, le consentement à payer médian s’élevait à 15,65 $ par mois durant la saison estivale. Les répondants qui ont indiqué avoir de bonnes connaissances sur l’eau sont plus susceptibles d’appuyer l’imposition d’une taxe. Les caractéristiques démographiques et les attitudes des répondants envers la rareté et la gestion de l’eau influencent la probabilité d’appuyer l’imposition d’une taxe. 相似文献
