This study presents how Hydro-Quebec manages its short-term financial risks. The quantitative hedging model is articulated over forward and volatility premia and constrained by a yearly risk limit provided by the firm's Finance Committee. The hedging solutions provide the optimal linear hedging parameters and option strike levels. The second part of the paper is devoted to a theoretical analysis of the sensitivity of the optimal solutions to changes in the premia, by means of the general implicit function theorem.  相似文献

On the basis of historical data aggregated over the period 1973 to 2000, we have experimented with four different approaches to estimate the synthetic euro's equilibrium exchange rate. Using a number of competing models with the same data set, variable definitions and sample period offers the possibility to assess the uncertainty surrounding such equilibrium levels, both from an empirical (different estimates) and a theoretical viewpoint (different specifications). In this exercise, the 'Rest of the World' is proxied by the US, the UK, Japan and Switzerland, aggregated on the basis of trade weights.
We employed reduced form co–integration models, a structural VAR, a NATREX model (estimated in structural form) and the ECB's small–sized euro area wide macro–econometric model. In this order the approaches feature an increasing degree of 'structure', in the sense of the constraints based on economic theory embedded in the econometric models that were estimated. The results confirm the high likelihood for the euro having been undervalued in Q4 2000, while stressing the significant empirical and theoretical uncertainty with respect to the equilibrium exchange rate level.  相似文献

This paper argues that evaluations of public–private partnerships thus far point to contradictory results regarding their effectiveness and value-for-money. Despite continuing political popularity, greater care is needed to strengthen future evaluations and conduct such assessments away from the policy cheerleaders.  相似文献

This research note involves an investigation of some conceptual issues which arise in the coexistence of direct and indirect forms of participation in three case studies of South African organizations. It is concluded that a managerial paradigm shift from a strong individualistic orientation towards collaborative or collective values could facilitate the process of achieving both economic growth and equity in the workplace.

This paper discusses the entrepreneurial landscape in Africa and locates a new generation of African entrepreneurs and their business networks within it. Unlike others in that landscape (i.e. micro- or small-scale informal sector vendors, and traditional or multinational large-scale formal sector firms), the ‘new generation’ entrepreneurs are business globalists who organized a system of business enterprise networks consisting of national, regional, and pan-African organizations. The study analyses interview data from 57 men and women network members from 10 countries (Botswana, Ethiopia, Ghana, Kenya, Mali, Senegal, South Africa, Uganda, Zambia, and Zimbabwe). Some defining characteristics of these entrepreneurs are interactive social and business relationships, use of modern management methods and information technology, trust among fellow members, transparent business practices, advocacy on behalf of the private sector, and commitment to increasing intra-African commerce. Their mission is to improve the climate for private sector business in Africa and to promote regional economic integration. They pursue cross-national commercial ventures, maintain official observer status at established regional economic organizations, sign memoranda of understanding with multilateral agencies, establish venture capital funds, and help to change government policies. The paper identifies characteristics of the ‘new generation’ entrepreneurs, evaluates goals and achievements of their networks, and concludes that despite limitations, these entrepreneurs and their organizations have created intra- and cross-national networks that strengthen private-sector-led economic growth in Africa.  相似文献

Within the recent literature on the geography of new firm formation, much attention is given to the role of regional knowledge sources based on the Knowledge Spillover Theory of Entrepreneurship. At the same time, several other studies show the importance of agglomeration economies for new firm formation. The goal of this study is to assess the relative importance of these determinants for differences in the share of employment creation from new firms at the level of municipalities for the period of 1999–2006 in the Netherlands. It is found that the traditional drivers of new firm formation, such as economic growth and agglomeration effects, have a much stronger effect on new firm formation compared to measures of the regional knowledge base. Moreover, it is shown that when not correcting for the presence of agglomeration effects, the role of local knowledge resources is easily over-estimated, pointing to the dangers of misspecifications of models. The results imply that the knowledge spillover theory of entrepreneurship should, at least for the Netherlands, not be exaggerated.  相似文献

Leaders with global skills are in demand by MNCs. Global management skills depend on the applicability of management practices across cultures. Using data from managers in 50 countries, this study examines the interaction effect of cultural values and managerial skills on two outcomes, employees' attitudes and workgroup effectiveness. Our results indicate that cultural values tend to have a greater effect when a manager is less skilled than when the manager is highly skilled. When the manager is highly skilled, the interaction effects of culture tend to disappear. The practical and research implications of these findings are discussed.  相似文献

This paper describes a model developed to measure customer satisfaction with enterprise training programmes. Based on developments in customer satisfaction and quality measurement, it is proposed as an alternative to the training evaluation model developed by Kirkpatrick (1959). A single indicator, a Customer Satisfaction Index (CSI), quantifies the level of satisfaction with each training programme. The model also measures the individual parameters that contribute to the CSI, as well as their relative importance. It facilitates a benchmarking process regarding these parameters and between training programmes. The development process of the model is described, as is its use in practice.  相似文献

Transaction costs are barriers for internationalisation processes. This paper investigates the practical relevance of transaction costs economics (TCE) for international supply chain management (SCM) in this era of globalisation, which is characterised by splitting up the supply chain in more and more parts. The analysis is based on data from in-depth interviews with seven manufacturing companies in the Netherlands which are actually engaged in this modern way of organising production. It is shown that the balance between transaction costs and sheer production costs (transformation costs) plays a prominent role in the strategic decisions on how and where to organise production. Especially intangible (or ‘soft’) transaction costs are important in this respect. The analysis provides insight in practical experience in the manufacturing industry in the Netherlands with transaction costs and shows how transaction costs affect decisions on transaction management, personnel policy and internationalisation of R&D. This study is to our knowledge the first to confront the theory of TCE with practice of manufacturing firms in their internationalisation decisions using in-depth interviews instead of survey data.  相似文献

The evidence on rank and income mobility in China reveals an important change around the year 2000. Using panel data from the China Health and Nutrition Survey we show that rank mobility fell markedly from the decade immediately preceding the millennium to the decade immediately following: in this respect China is becoming noticeably more rigid. By contrast income mobility has carried on increasing; so has income inequality. The simultaneous increase in rigidity and inequality presents China with a challenging policy problem.  相似文献
