The tactical and strategic value of hedge fund strategies: a cointegration approach

This paper analyzes long-term comovements between hedge fund strategies and traditional asset classes using multivariate cointegration methodology. Since cointegrated assets are tied together over the long run, a portfolio consisting of these assets will have lower long-term volatility. Thus, if the presence of cointegration lowers uncertainty, risk-averse investors should prefer assets that are cointegrated. Long-term (passive) investors can benefit from the knowledge of cointegrating relationships, while the built-in error correction mechanism allows active asset managers to anticipate short-run price movements. The empirical results indicate there is a long-run relationship between specific hedge fund strategies and traditional financial assets. Thus, the benefits of different hedge fund strategies are much less than suggested by correlation analysis and portfolio optimization. However, certain strategies combined with specific stock market segments offer portfolio managers adequate diversification potential, especially in the framework of tactical asset allocation.

Austrian economics and the analysis of labor markets

Theory and policy relating to labor markets is dominated by the mainstream labor market model, although a less well-known, socioeconomic version can also be identified. The mainstream model is methodologically flawed and forced, thereby, to relegate any (serious) investigation of labor market institutions and/or social structures to the margins of its analysis. The socioeconomic account is not so much methodologically flawed, as methodologically ambivalent. While this ambivalence does not actually prevent the investigation of institutions and/or social structures, it does promote ambiguity whenever we inquire into the precise nature of the interaction between them and labor markets. Insights from Austrian economics, when used in collaboration with critical realist methodology, can play a part in augmenting the socioeconomic account, generating a totally new approach to the analysis of labor markets.

Labour Market Adjustments to Exchange Rate Fluctuations: Evidence from Canadian Manufacturing Industries

This paper provides some of the first empirical evidence on labour market adjustments to exchange rate movements in Canadian manufacturing industries. Controlling for endogeneity using generalized method of moments estimation, it is found that during the 1981–1997 period, exchange movements have a substantial impact on labour input and that this impact has grown over time as the manufacturing industries have become more exposed to trade. In contrast, the exchange rate effect on real wages is estimated to be virtually zero for all manufacturing industries.

科技型中小企业特征与资本市场的错位关系研究

随着社会经济的快速发展,中国已经进入了经济转型期,企业群体的构成也发生了较大变化,科技型中小企业成为当前我国经济发展的重要组成部分。但是,我国现有资本市场的结构和制度安排主要服务于各行业中业绩稳定,具有可持续发展潜力的传统产业中的大中型企业,而科技型中小企业由于规模小,无形资产比重大、业绩不稳定等特征很难得到资本市场的支持。在国家提出自主创新战略背景下,研究资本市场如何为科技型中小企业服务,加快我国产业结构升级,是个迫切需要解决的问题。本文通过对部分国家高新区的调研发现,现阶段科技型中小企业的一些特征与资本市场和服务机构之间均存在一定的错位关系。为解决这些错位关系,提出了未来我国资本市场制度建设的相关建议。

The effects of market orientation on subsidiary performance: Empirical evidence from MNCs in Turkey

Much scholarly work has been devoted to studying the performance implications of market orientation. This study examines the direct and indirect effects of market orientation on financial performance of the subsidiaries of MNCs located in Turkey. The findings indicate that a market orientation affects financial performance of MNC subsidiaries that operate in diverse and complex economic, cultural, and political environments of the Middle East. Moreover, authors demonstrate that the customer-related mechanisms (customer satisfaction and retention) mediate the market orientation–performance relationship. The paper also discusses the theoretical and practical implications of study findings.     

企业退出出口市场行为与企业的经营表现——基于倾向评分匹配的经验分析

文章运用倾向评分匹配方法分析了企业退出出口市场行为对其经营表现的影响。研究结果表明,经营表现越差的出口企业退出出口市场的概率越大;企业退出出口市场行为对企业经营表现的影响主要体现在影响就业增长和产出增长方面,而对劳动生产率的影响总体不显著。具体表现为,企业退出出口市场会对其就业增长和产出增长产生持续的显著负向作用,这说明我国国内需求尚不足以使企业退出出口市场后继续保持退出前的就业增长率和产出增长率。因此,在提倡出口转内销的同时需注重提高出口企业在国际市场竞争中的存活率。     

Revisiting the risk/return relations in the Asian Pacific markets: New evidence from alternative models

This paper examines the risk/return relations in eleven Asian Pacific stock markets and explores if the 1997 Asian financial crisis significantly influenced market behavior in the region. We use a plain vanilla time-series regression approach as well as various GARCH models. Although results significantly vary across model specifications, the overall evidence from GARCH models supports a significantly positive risk/return relation in several markets but only prior to the Asian financial crisis. These results accord with Glosten et al. (1993) and Harvey (2001) and suggest that the relative risk aversion is sensitive to both model specifications and structural breaks.     

Hub location problems in transportation networks

In this paper we propose a 4-index formulation for the uncapacitated multiple allocation hub location problem tailored for urban transport and liner shipping network design. This formulation is very tight and most of the tractable instances for MIP solvers are optimally solvable at the root node. While the existing state-of-the-art MIP solvers fail to solve even small size instances of problem, our accelerated and efficient primal (Benders) decomposition solves larger ones. In addition, a very efficient greedy heuristic, proven to be capable of obtaining high quality solutions, is proposed. We also introduce fixed cost values for Australian Post (AP) dataset.     

Country-of-origin effects and antecedents of industrial brand equity

Does the country-of-origin effect matter to industrial brand equity in international business-to-business (B2B) markets? The effect of a product's country-of-origin (COO) on both industrial buyers' and consumers' perceptions and evaluations has been one of the most widely studied phenomena in the fields of international business, marketing, and consumer behavior since the 1960s. Although many country-of-origin studies focus on consumer behavior in developed countries and acknowledge that the processes and stages of economic development by which consumers use COO information may differ in developing countries, the fact that there has been little research to investigate the effects of COO could explain the variations in international buyers' evaluations of industrial brand equity in the newly-industrialized economies, such as Taiwan. Taiwanese firms are now formidable global B2B market players by successfully transforming themselves from manufacturing mainly low-value and labor-intensive goods to producing many high value-added products that require advanced technology, equipment and significant business expertise. With the adoption of advanced technology and equipment, an important question is whether unique and innovative fastener products from Taiwan have generated the country-of-origin effects in international B2B buyers' minds. The main finding is that the country-of-origin of fasteners has not yet become an important antecedent of industrial brand equity in the case of the fastener industry in Taiwan.
