Regression-based testing techniques have long been used to quantify whether the efficient frontier of a set of assets spans the frontier of a larger collection of investments. This paper derives regression-based spanning tests for the case in which the investment possibilities set contains, or is constituted by, futures contracts for which marked-to-market margins are explicitly taken into account. Two empirical applications illustrate our results. 相似文献

The last five decades have witnessed a profound evolution of economic policy in developing countries, particularly in the case of trade strategies. Both internal, as well as external, factors have prompted the need for more outward‐oriented (or liberalised) trade policy regimes. The creation of the General Agreement on Tariffs and Trade (GATT) in 1947 and the World Trade Organisation (WTO) in 1995 have been important driving forces for free trade. Since then, the major quantitative barriers to trade, i.e. tariffs and non‐tariff barriers (quotas, licences and technical specifications, among other restrictions), have substantially been reduced or dismantled. Also, the progress towards more liberalised trade regimes, mainly in developing countries, has been manifested in the trade and development literature. Major studies suggest that the performance of more outward‐oriented economies is superior to that of those countries pursuing more inward‐looking trade practices (Greenaway and Nam, 1988; Dollar, 1992; Sachs and Warner, 1995; and Rodríguez and Rodrik, 2000). Recent developments in the international trade literature focus on the potential dynamic effects of trade liberalisation, i.e. simplification of tariff structures and elimination of non‐tariff barriers, in reducing the incentives to rent seeking and in accelerating the flow of technical knowledge from the world market. Moreover, there have been important advances regarding the study of trade liberalisation and its impact on exports, imports and the balance of payments, largely neglected in the literature, often driven by supply‐side considerations. 相似文献

(1252) Tegegne Gebre‐Egziabher This paper examines the developmental impact of China and India on Ethiopia by examining macro‐level trade, investment and aid relation, and micro‐level impacts on local micro and small‐scale footwear producers. Both secondary and primary data were used. At macro level there are clear evidences of an increase in trade between Ethiopia on the one hand and China and India on the other, though the trade balance disfavours Ethiopia. China has displaced other countries as export destinations for Ethiopia. Similarly, the presence of China and India is also felt in the areas of investment and aid. At local level, Chinese imports of footwear have forced local enterprises to downsize their activity and lose assets and money. At the same time, however, firms have followed both the high road of competition (design and quality improvement, investment in machinery, product specialisation) and the low road of competition (lowering price and profit, reducing raw materials and inputs, and joining the informal sector) to withstand the impact of Chinese imports. The long‐term effect of Chinese imports is to crowd out local efforts of using the sector as the basis for industrialisation. Government, non‐government organisations and local producers should work together in order to withstand the negative impacts of footwear imports by raising the competitiveness of the local producers. 相似文献

In expanding their market to the global level with clear and consistent global brand images across nations, marketers are ever confronting the issue of how to deal with different cultural values. Cultural value is identified as an influential factor on brand image and is widely accepted as one of the crucial concepts in understanding consumer consumption value, which determines choices of consuming everyday products and services. Most firms endeavoring to establish and maintain consistent global brand images, however, adopt a standardized brand image strategy that usually does not consider individual target markets” characteristics, including the concepts of cultural value and consumption value. This study developed a conceptual framework which incorporated cultural value not only as a direct antecedent of brand image, but also as an indirect antecedent of brand image through consumption value, and empirically tested it using the category of apparel. Following this framework, this study hypothesized the differences in brand image, cultural value, and consumption value between the U.S. and South Korea. Data were gathered through surveying university students residing in the San Francisco and Seoul metropolitan areas using a convenience sampling method. A total of 329 completed questionnaires were used in factor analysis, discriminant analysis, and structural equation modeling. The results provide insights into standardized brand image strategies and suggest some implementable tools that might prove effective in both countries. © 2009 Wiley Periodicals, Inc. 相似文献

Substantial progress has been made in developing more realistic option pricing models for S&P 500 index (SPX) options. Empirically, however, it is not known whether and by how much each generalization of SPX price dynamics improves VIX option pricing. This article fills this gap by first deriving a VIX option model that reconciles the most general price processes of the SPX in the literature. The relative empirical performance of several models of distinct interest is examined. Our results show that state‐dependent price jumps and volatility jumps are important for pricing VIX options. © 2009 Wiley Periodicals, Inc. Jrl Fut Mark 29:523–543, 2009 相似文献

By referring to research on the measurement of the Big Five personality factors, this article investigates measurement characteristics of brand personality (BP) dimensions. The authors apply a meta‐analysis and investigate the intercorrelations and reliabilities of the BP dimensions of Sincerity, Excitement, Competence, Sophistication, and Ruggedness, as suggested by Aaker (1997). Similar to the Big Five personality factors, the measurement of BP reveals interdependence of the dimensions and one General Personality Factor. Furthermore, the reliabilities reveal instability across method characteristics, for instance, the use of facets as opposed to traits in measuring BP drives up the reliabilities of those dimensions with a larger number of items (e.g., Sincerity). Finally, as with the Big Five, the BP dimensions show differential effects on performance measures (as assessed by brand attitude) and thus support the predictive power of the single dimensions. The findings provide insights into the dimensional structure of BP and its stability, and support the transferability of the Big Five personality factors to nonhuman domains. Importantly, the article outlines relevant avenues for future research on BP measurement. 相似文献

This study examines the significant differences in shopping for luxury goods among Western, Asian, and Hispanic tourists and, in particular, the perceived importance of different types and characteristics of the luxury consumer and travel goods tourists buy on vacation. The results show that Western, Asian, and Hispanic tourists‐shoppers significantly differ in the perceived importance of luxury consumer and travel goods and their characteristics. Western and Asian tourists attach more importance to buying “gifts for others” than Hispanic tourists. Asian tourists attach more importance to buying “golf equipment,” “health spa/wellness treatment,” “luxury cruises,”and “luxury yachts/rentals” than Hispanic tourists. Western tourists attach more importance to “fine dining” than Hispanic tourists. Implications of the study results and recommendations for future studies are discussed. 相似文献

Interventionist thinkers are now claiming intellectual victory, blaming the free‐market system and its ideology for the current economic collapse. We find this thesis untenable, drawing on the Austrian Business Cycle Theory. Instead, we argue that the roots of our present downturn lie in the monetary system, whose institutional structure is far from any free‐market ideal. Moreover, several government policies have contributed to the problems. 相似文献
