We study information flows across four wheat futures markets on four continents: Zhengzhou Commodity Exchange (ZCE), South African Futures Exchange (SAFEX), Euronext/Liffe and Kansas City Board of Trade (KCBT). Three approaches for studying information flows among non‐synchronous markets are applied: cointegration techniques, vector autoregressive analysis and multiple regression proposed. Although comparable underlying assets are traded in the four markets, our results indicate that no long‐run links exist among them. ZCE is by far the most endogenous market, and Euronext/Liffe is the most exogenous one. Finally, the model points to KCBT as the most influential and sensitive wheat market. Our findings indicate that the relative openness of the SAFEX wheat market supports information flows and linkages from KCBT and Euronext/Liffe. Therefore, our results suggest that more supportive policies to incentivise higher wheat production in South Africa are required to mitigate the impact of price shocks emanating from the global wheat markets.  相似文献

Deprived housing is recognized as a source of poor health, but there is still little evidence of a causal relationship between housing and health. While existing literature identifies neighborhood effects and the individual dwelling as factors which affect health, it does not offer a joint examination of these factors. Moreover, endogeneity is a concern in analyses of both problems. Thus far, studies addressing endogeneity have done so through experimental design or instrumental variables. The first approach suffers from problems of external validity and the latter from the lack of reliable instruments. We therefore adopt an alternative strategy which considers both sources of endogeneity in order to identify the effects of housing on health by estimating fixed‐effect models. We reveal how housing problems affect health depending on living conditions and socioeconomic status. Our results therefore indicate that living in poor housing is an important short‐term socioeconomic determinant that directly affects health.  相似文献

This article proposes and validates a financial protection perception scale (FPPS) from the perspective of the financial services consumer. The scale was applied to a sample of 1137 individuals residing in Brazil and validated using exploratory and confirmatory factor analysis and standard multivariate validation methods. The FPPS, composed of 14 items, allows the development of an indicator that defines the level of protection perceived by the consumer of financial services, evaluated along the dimensions of transparency, suitability, security, and complaints. The tests and fit indices indicated the reliability and validity of the FPPS. With this scale, researchers, managers, and policymakers can assess the extent to which consumers feel protected when using financial services.  相似文献

This study develops a world spatial equilibrium softwood lumber model comprised of the major importing and exporting countries/regions to analyse the impacts of global trade reform on the world softwood lumber market. The results show that free trade leads to an increase in lumber trade, and Canadian producers and US consumers are the biggest beneficiaries. Trade liberalization improves the overall world welfare as world producer and consumer surpluses increase. The result highlights the importance of moving towards free trade in the global softwood lumber market.  相似文献

The World Bank has suggested the need to enhance Information and Communication Technology skills in all sectors because a 10% increase in internet connectivity was found to boost GDP growth by 1.38%. Simultaneously, the OECD argued that high internet access rates generate a 2% increase in GDP. Because the internet positively affects economic growth, we investigated the relationship between an economically active population, human capital and technology to evaluate these effects in Mexico. A data series from 1991 to 2010 was analysed in three stages according to the least-squares method. A Cobb–Douglas function under the Solow model was considered. Technology and internet access were found to positively affect top-level students and graduate students and thus contribute to the global innovation index.  相似文献

Disasters are extraordinary situations that require significant logistical deployment to transport equipment and humanitarian goods in order to help and provide relief to victims. An efficient response helps to reduce the social, economic and environmental impacts. In this paper, we define and formulate a practical transportation problem often encountered by crisis managers in emergency situations. Since optimal solutions to such a formulation may be achieved only for very small-size instances, we developed an efficient genetic algorithm to deal with realistic situations. This algorithm produces near optimal solutions in relatively short computation times and is fast enough to be used interactively in a decision-support system, providing high-quality transportation plans to emergency managers.  相似文献

Rapid industrialisation in Asia is generating a significant new demand for raw materials and pressure on local, regional and global environments. In the future these demands and pressures are expected to increase markedly. These concerns are models of development that assume that economic growth follows a pattern leading to a convergence between the structure, growth and productivity of economies over the long run. In these models, the structure of industries and sectors, technological capabilities and consumer preferences are regarded as converging towards patterns established in more advanced economies. By extension, convergence is also assumed to hold for the resource intensity and environmental pressure associated with growth in industrialising countries. This paper argues for greater attention to the resource and environmental quality of development. It argues that by applying ideas from an emerging literature on ‘systems innovation’ it becomes possible to envisage the emergence of new, more resource-efficient socio-technical systems as the basis of more sustainable development pathways in developing Asia. Such sustainable socio-technical systems will emerge in the context of interaction between domestic and globalised markets, knowledge flows and governance. Key issues for a research agenda are set out.  相似文献

Human resources audit   总被引:4,自引:0,他引:4  
Human resource management (HRM) has experienced a strong evolution. In order to provide useful information to managers, it is necessary to evaluate the results generated by the design and implementation of personnel policies. This is the goal of the HR audit that includes two different analyses and valuations: the HR policies and their level of fit with the strategy of the firm, and the characteristics of human capital. Several criteria have been used to assess different HR policies. Nevertheless, the measurement of the value that human capital brings to the firm is a very complex topic. Consequently, different models are being presented that aim to properly solve this challenge. This paper will analyze the HR function from two perspectives: the evaluation of the implemented policies and the quality of human capital in relation to real competencies, and the capability to learn and develop new skills.  相似文献
