我国蜂蜜贸易国际竞争力的比较分析

根据FAOSTAT和中国统计年鉴等提供的最新数据,在运用市场占有率、显示性对称比较优势分析和综合竞争力分析的基础上,综合测算和分析了我国蜂蜜贸易竞争力的变化。结果表明,2002年后我国蜂蜜的竞争力不降反升,已超越加拿大,但较阿根廷低。原因在于2002年以来,我国蜂蜜质量的整体提高和蜂蜜营销能力的增强,直接导致国际竞争力得到提高。因此,要提高我国蜂蜜的国际竞争力就要转变长期依靠价格竞争的方式,着重蜂产品质量和企业营销能力两个方面的提高,变贸易劣势为优势。最后,提出了增强我国蜂蜜国际竞争力的六条建议。

The impact of changes to the human resources function in Australia

With the rapid development of information technology (IT) in the late twentieth century, a 'real-time' global economy is now taking shape. The social costs of being networked in the global economy vary across nations and regions. Some report job losses and fragmented working conditions, and in general social structure is endangered. The idea of maintaining a nation's social safety net and the traditional concept of the welfare state is now challenged. In this article, we deal with three issues. First, we point out that new social risks are formed by the structural change in the labour market. Second, the interaction of the nation-state and global economy is addressed; in facing new social risks, we argue, the role of nation-state is still important. However, the traditional paradigm of the welfare state needs to be re-conceptualized. Third, with the expanding view of the welfare state, this paper examines the developments of constructive welfare policies and discusses the social transformation processes in Singapore, especially in the face of the new social risks caused by globalization.     

Rebates in a Bertrand game

We study a price competition game in which customers are heterogeneous in the rebates they get from either of two firms. We characterize the transition between competitive pricing (without rebates), mixed strategy equilibrium (for intermediate rebates), and monopoly pricing (for larger rebates).     

Listen to the market: Do its complexity and signals make companies more innovative?

This paper analyzes four modes of innovation that differ in their scope of newness (innovation generation and adoption) and in their degree of change (radical and incremental). Building a theoretical model based on the market orientation (MO) and contingency theory literature and using a sample of innovative firms, we find that MO positively influences the numbers of incremental generation and adoption of innovations. We also find that environmental complexity moderates the relationship between MO and radical and incremental innovation generation and the number of incremental innovation adoption. That is, we have found that highly complex environments enhance the introduction of radical and incremental internally generated innovations and harm the adoption of incremental innovation for market-oriented firms. These findings add to the innovation and MO literatures. Our results also have important implications for both the commercial activities and R&D policies of firms.     

Contributions of design emphasis,design resources and design excellence to market performance in technology-based service innovation

The value of design in product innovation is widely acknowledged and supported by empirical research, although extant research tends to focus solely on the role of designers, or design excellence, or design emphasis. Design in the context of service innovation is less well understood. Technology-based firms are viewed as key loci of innovation and, indeed, this innovation is not limited to product innovation, even though many of the stereotypes that come to mind have to do with the development of ever more technologically advanced ‘widgets’. In response to the gaps in current literature, this work takes a holistic approach to measuring design and examines how design resources (designers), design emphasis (emphasis on aesthetics and experience) and the outcomes of design (design excellence) jointly contribute to market performance in technology-based firms engaged in service innovation. Based on a survey conducted among managers of 176 technology-based service firms and evaluations of design excellence by design experts, the findings suggest that design emphasis and design resources both contribute to market performance. Surprisingly, design excellence is not found to contribute to market performance and possible reasons for this are discussed.     

How tournament incentives affect asset markets: A comparison between winner-take-all tournaments and elimination contests

We investigate the impact of investment managers׳ tournament incentives on investment strategies and market efficiency, distinguishing between winner-take-all tournaments (WTA), where a minority wins, and elimination contests (EC), where a majority wins. Theoretically, we show that investment managers play heterogeneous strategies in WTA and homogeneous strategies in EC, and markets are more prone to mispricing in WTA than in EC. Experimentally, we find that investment managers play more heterogeneous strategies in WTA than in EC, but this does not trigger significant differences in prices. Moreover, prices in WTA and EC do not differ significantly from markets composed of linearly incentivized subjects.     

Business incubation models and institutionally void environments

This paper builds a conceptual framework of business incubation models in institutionally void environments, a relevant yet understudied topic in the extant literature. On the basis of a qualitative approach based on the analysis of five case studies drawn from a sample of business incubators in Egypt, and grounding on the literature on institutional voids, we posit that there is a necessity for two different incubation models in institutional laggard environments, typically found in, yet not limited to, developing countries. In particular, we show evidence that the two models supply and facilitate different needs of entrepreneurs, in different stages of entrepreneurial life cycle. We further argue that the incubation model choice is contingent on the incubator sponsors, i.e. affiliation of the incubator, mainly through available resources and imposed objectives. Finally, we offer implications for policy makers who can use the framework to design the regulations in a way that will stimulate appropriate incubator creation and hence sustain local entrepreneurship, as well as for incubator managers who can follow the findings to position their incubation model in line with their resources, capabilities and objectives.     

Simple agent-based dynamical system models for efficient financial markets: Theory and examples

We propose an agent-based framework, based on simple piecewise linear time-invariant continuous-time dynamical systems models, as a means for describing efficient financial markets. We show by examples that many of the common agent-specific trading strategies occurring in the academic literature, including chartists and fundamentalists of various kinds, can be described in the proposed framework. We present definitions for weak and strong market efficiency and provide necessary and sufficient conditions for them to hold. We present minimal examples of strongly and weakly efficient markets to show that these concepts are natural and easy to satisfy in agent-based models, and that the models can reproduce both statistical and behavioral stylized facts of real markets. We provide examples to demonstrate that the framework can be extended for agents with delays in information processing, as well as for agents with time-varying strategies and for nonlinear market impact functions. We also provide a counterexample to show that the proposed market efficiency concepts may require modification in generalizations for nonlinear trading strategies.     

Location of trade,return comovements,and diversification benefits: Evidence from Asian country ETFs

Using data from the Asian country ETFs and their MSCI indices, this paper examines whether trading location affects return comovements and diversification benefits. Our empirical results show that the magnitude of return comovements for the Asian country ETFs is higher than the corresponding MSCI indices. Moreover, our empirical findings indicate that the factors, including investor sentiment, market conditions, and economic fundamentals of the U.S. market, have greater effects on the return comovements for the Asian country ETFs than their underlying MSCI indices. Finally, the evidence presents a higher diversification benefit for the Asian MSCI indices than the Asian country ETFs.
