ABSTRACT

How do political agendas impact on strategic planning practices? This article shows that recent changes to the framework for managing government priorities have made Lithuania’s strategic planning system more politically responsive by mobilizing political attention, leadership and state funding to major government commitments. However, these changes have not yet translated into any longer term outcomes because policy implementation practices did not change very much.  相似文献

Paul Embrechts was born in Schoten, Belgium, on 3 February 1953. He holds a Licentiaat in Mathematics from Universiteit Antwerpen (1975) and a DSc from Katholieke Universiteit Leuven (1979), where he was also a Research Assistant from 1975 to 1983. He then held a lectureship in Statistics at Imperial College, London (1983–1985) and was a Docent at Limburgs Universitair Centrum, Belgium (1985–1989) before joining ETH Zürich as a Full Professor of Mathematics in 1989, where he remained until his retirement as an Emeritus in 2018. A renowned specialist of extreme-value theory and quantitative risk management, he authored or coauthored nearly 200 scientific papers and five books, including the highly influential ‘Modelling of Extremal Events for Insurance and Finance’ (Springer, 1997) and ‘Quantitative Risk Management: Concepts, Techniques and Tools’ (Princeton University Press, 2005, 2015). He served in numerous editorial capacities, notably as Editor-in-Chief of the ASTIN Bulletin (1996–2005). Praised for his natural leadership and exceptional communication skills, he helped to bridge the gap between academia and industry through the foundation of RiskLab Switzerland and his sustained leadership for nearly 20 years. He gave numerous prestigious invited and keynote lectures worldwide and served as a member of the board of, or consultant for, various banks, insurance companies and international regulatory authorities. His work was recognised through several visiting positions, including at the Oxford-Man Institute, and many awards. He is, inter alia, an Elected Fellow of the Institute of Mathematical Statistics (1995) and the American Statistical Association (2014), an Honorary Fellow of the Institute and the Faculty of Actuaries (2000), Honorary Member of the Belgian (2010) and French (2015) Institute of Actuaries and was granted four honorary degrees (University of Waterloo, 2007; Heriot-Watt University, 2011; Université catholique de Louvain, 2012; City, University of London, 2017). The following conversation took place in Paul's office at ETH Zürich, 17–18 December 2018.  相似文献

Over the past twenty-five years, wage inequality has fallen in Slovenia, even as it has risen in most developed economies. The rates of return to education and work experience rose and remained high on average. However, rapid increases in the number of college graduates have outpaced the rising relative demand for skill among the youngest labor market entrants. As a result, the youngest cohorts of college graduates have experienced declining returns to education and a downward shift in their occupational distribution, which has not been experienced by older college graduates. These changes coincide with the implementation of the Bologna Reform, which reduced the length of time necessary to complete a bachelor’s degree and contributed to the incentives to attend college. Falling returns to tertiary education contributed to declining within-cohort wage inequality among the young, which was large enough to reduce overall wage inequality.  相似文献

Summary A special application of the truncation problem is presented in connection with constructing a model for the analysis of the fine aerosol spray particle size distribution sampled by an impact method. The relationship between the diameter distribution of images recorded on a photograph and the actual spherical particle diameter distribution is analyzed. The problem of estimating the parameters of the actual diameter distribution using the induced information is transformed to estimating the parameters of a truncated distribution with known or unknown truncation point. The derived general solution is implemented to two specified particle size distributions.  相似文献

This article shows that a multiproduct firm has incentives to obfuscate its products by using search costs to induce consumers to search through its products in a particular order. The consumers who draw high valuations of the first product terminate their search earlier than the consumers who draw low valuations. Thus, the firm has incentives to raise the price of the earlier searched product. The optimal search cost for an obfuscated product is such that consumers inspect the product only if the match values of the previously searched goods have been very poor.  相似文献

Number of patents may be developed on the basis on different natural and science and technological factors. Number of patents prediction based on the different factors in many countries is analyzed in this investigation. These factors represent natural and science resources. The method of ANFIS (adaptive neuro fuzzy inference system) was applied to the data in order to select the most influential factors for the number of patents prediction. Five inputs are considered: research and development (R&D) resources, natural resources, quality of academic institutions, quality of collaboration with the private sector and quality of education. As the ANFIS output, number of patents is considered. The ANFIS process for variable selection is also implemented in order to detect the predominant factors affecting the prediction of number of patents. Results show that the R&D is the most influential factor for the number of patents prediction.  相似文献

The aim of this paper is to evaluate merger control as a segment of competition policy in less developed countries (LDCs) and to propose desirable regimes, using economic growth as the evaluation standard. Three regimes of merger control are recommended, depending on the level of institutional and economic development: for LDCs with low levels of both, the absence of merger control is suitable; for LDCs with intermediate levels of both, very restricted merger control is recommended; this should evolve into somewhat restricted merger control for the remaining LDCs. Advocacy is recommended as the main substitute activity of the national competition authorities.

This paper investigates the determinants of the structural (between-sectoral) and productive (within-sectoral) transformation of 56 NUTS2 regions in Central and East European (CEE) countries over the 2008–2014 period. Over the analysed period, a transformation of the analysed regions has taken place towards the tertiary sector and high value-added activities. The results from a spatial panel Durbin analysis reveal the existence of product-space linkages and point to a productive transformation towards high technology-intensive activities as an important driver of industrial development. Equal access to digital infrastructure in urban and rural areas and transfer of skills, knowledge and resources through the inflow of foreign investment and imports of production inputs increase the contribution of manufacturing to regional employment. The effect of profit tax reductions on the share of manufacturing employment is about five times larger than the effect of government subsidies to production.  相似文献

This paper explores how personal and situational factors impact consumer expectations of Corporate Social Responsibility (CSR). Consumer expectations are known to motivate marketers to incorporate social considerations into their marketing practices and to communicate about those actions. A study was conducted in order to examine the effect of values and issue involvement on consumer CSR expectations, categorised as economic, legal, ethical, and philanthropic. The study's findings demonstrated that consumers generally have high expectations of CSR, especially in the legal and ethical‐philanthropic domains. Expectations for the ethical‐philanthropic dimension of CSR are higher amongst consumers holding high self‐transcendent values and practicing high involvement. The main implications of the study are the potential for positioning companies as socially responsible and incorporating CSR in strategic marketing and communications decisions.  相似文献
