In light of the ongoing liberalization of electricity trade in the Nordic countries, and perhaps in Northern Europe, we argue that gains from electricity trade may be different from those traditionally associated with comparative advantages and economies of scale. In particular, we consider gains arising from the exploitation of technological complementarities between hydro and thermal systems. Our theoretical framework highlights essential features of the two systems and allows for an analysis of effects of trade. We study three trading regimes, which may arise either endogenously or because of trade regulations: day–night power exchange, seasonal energy banking and unbalanced trade. The analysis suggests that gradual trade liberalization may be costly. 相似文献

Organizational knowledge creation integrates context, knowledge assets, and knowledge creation processes throughout the organization. Using organizational knowledge creation theory as an organizing framework, we conduct a literature review that shows prior work has focused on the role of central, upper‐echelon, leadership in knowledge creation processes, without devoting much attention to context and knowledge assets. To remedy these weaknesses, we develop a new framework for situational leadership in organizational knowledge creation. The framework is based on a continuum that ranges from centralized to distributed leadership at three layers of activity: a core layer of local knowledge creation; a conditional layer that provides the resources and context for knowledge creation; and a structural layer that forms the overall frame and direction for knowledge creation in the organization. We discuss the implications of this framework for theory and practice. 相似文献

This paper investigates sourcing decisions for new ventures. Sourcing decisions are especially problematic for start-ups because they lack resources, knowledge and legitimacy to evaluate and interact with suppliers. We develop and apply a framework that connects global sourcing, relationship development and attractiveness. Further, we investigate how new ventures develop their first supply chains by conducting an exploratory multiple case study of six Norwegian start-ups. Based on our findings, we develop three propositions regarding how start-ups mediate their lack of attractiveness through pre-sales and by choosing shorter supply chains and smaller suppliers. The implications for practice include emphasizing the importance of developing a business relationship with the supplier in parallel with making sourcing decisions. This study is a novel contribution to an underexplored topic, and we conclude by proposing a research agenda for future explorations of start-ups and supply chain development. 相似文献

Using a large plant level data set, this paper carries out an econometric analysis of the environmental performance of multinational firms in the gold mining industry worldwide. The aim of the analysis is to determine if, by looking at the actual environmental performance of firms (as opposed to inferring such behavior from location decisions), we can shed any light on important questions in the literature on firm location decisions: Do pollution havens exist in the gold mining industry? Do foreign controlled gold mines perform environmentally worse or better than their domestic counterparts? We develop different ways of measuring environmental performance within the context of a Bayesian stochastic production frontier approach. In particular, we derive different ways of measuring technical and environmental efficiency. When we implement these methods in our empirical work, we find that results are robust across different models and ways of measuring efficiency. We find that gold mines exhibit a wide range of environmental efficiencies; some are clearly more efficient than others. However, and most importantly for our questions, we find that this variation in efficiencies cannot be systematically related to mine characteristics such as whether they are foreign or domestically controlled or whether they are located in developed versus developing countries. 相似文献

The purpose of the study was to study the circumstances and incidence rates of fatal accidents in inspection obligated and non-inspection obligated Danish fishing vessels to identify areas for prevention. Information about the fatalities came from maritime authority reports, including vessel disaster reports, post mortem reports, maritime inquiries and police reports. The person- and vessel years at risk came from the Danish Directorate of Fisheries. During the period 1989-2005, 114 fatalities occurred. Sixty-one of the fatalities occurred in 36 vessel disasters mainly caused by foundering/capsizing due to stability changes in rough weather and collisions; 39 fatal occupational accidents mainly occurred on the larger inspection obligated trawlers during fishing. In the remaining 14 other fatal accidents, the main causal factors were difficult embarking/disembarking conditions by darkness in foreign ports and alcohol intoxication. In the period 1995-2005, the overall incidence rate was 10 per 10,000 fishermen per year with no down-going trend during that period. The fatal accident rates are still too high, despite the efforts to reduce the risk. Increased focus on regular and repeated safety training for all fishermen and improved safety measures are needed, especially in the underscored areas of sea disasters concerning small vessels and occupational accidents on big vessels. Better registration of time at risk for fishermen is needed to validate the effect of the safety measures. 相似文献

Games of Climate Change with International Trade 总被引:1,自引:1,他引:1

We analyse games of greenhouse gas emission reduction in which the emissions and the emission reduction costs of one country depend on other countries' emission abatement. In an analytically tractable model, we show that international trade effects on costs and emissions can either increase or decrease incentives to reduce emissions and to cooperate on emission abatement; in some specifications, optimal emission reduction is unaffected by trade. We therefore specify the model further, calibrating it to larger models that estimate the costs of emission reduction, trade effects, and impacts of climate change. If trade effects are driven by total emission reduction costs of other countries cooperation is slightly more difficult than in the case without trade effects. If trade effects are determined by relative emission reduction efforts in other countries, cooperation becomes easier. Carbon leakage does not affect our qualitative insights, although it does change the numbers. 相似文献

ABSTRACT ** : This paper analyses the potential costs and benefits from patient driven competition between GPs and specialists by comparing gate-keeping with direct access to specialist care. The two access rules are compared under fee-for-service and capitation, on their performance at minimizing both total financial costs and patients' opportunity cost of time in care. To analyse the social cost of patients' potential access mistakes, two types of illnesses are considered, with two levels of severity and an equal probability for each of the four events. The results generated under information symmetry show that gate-keeping always dominates in terms of minimizing financial cost. Results are extended to show that under patients' heterogeneity with respect to time preferences, allocative efficiency can be enhanced in gate-keeping by giving the patient the option to seek a specialist directly, provided he bears the extra cost. When turning to information asymmetry, results are reversed, and direct access is shown to be more cost effective. This is due to patients' ability to constrain providers' opportunistic behaviour by 'voting with their feet'. Beyond increasing allocative efficiency, patient choice is therefore found, under certain conditions, to contribute towards enhancing productive efficiency. Finally, introducing co-payments to share the financial risk associated with direct access potentially weakens patients' ability to curb providers' strategic behaviour. Under information asymmetry, direct access to specialist care should therefore remain free if patient's disutility in time in care is linear. When it is instead increasing, we show that a co-payment becomes necessary to curb specialists' information rent. Finally, under information asymmetry, the mixed solution (gate-keeping with optional direct access) improves on pure gate-keeping but is still suboptimal. 相似文献

Abstract This article addresses the big welfare administration reform in Norway. The reform is a merger of the employment and national insurance administrations, combined with more formal collaboration with the local government social services administration. The reform introduced a mandatory partnership model between central and local government. This model is a hybrid of hierarchy and network. A substantial dilemma in the particular partnership model chosen is how to enhance vertical control at the same time as sustaining the autonomy of local government. The partnership model created to solve this dilemma represents a delicate and ambiguous balance between accountability to the central government and to the local council. 相似文献

The paper studies the role of labor market frictions in accounting for international business cycle comovement. To this aim, we embed labor market search and matching frictions in a two-country New Keynesian model. We show that labor market frictions amplify the international propagation of supply and demand shocks. In terms of cyclical properties then, they raise the cross-country output correlation. Adding labor market search in the New Keynesian model thus improves its ability to account for the business cycle comovement observed in G7 countries in the recent decades. Nominal wage rigidity substantially contributes to this result. Labor market institutions also play a role. Yet, their impact is not unequivocal depending on the institution considered. Business cycle synchronization is thus found to increase with the generosity of the unemployment benefits system, whereas it decreases with the strictness of employment protection. 相似文献
