Increasing livestock product consumption in many Asian countries has been accompanied by growth in some countries' imports of feedgrains for their domestic livestock sectors. This contributes to debate over future levels of grain imports. Yet projections often pay little attention to developments in livestock production. The impacts of technological catch-up in livestock production on trade in livestock and grains products among countries in the Asia-Pacific region are assessed. Tests are conducted of the hypothesis that productivity levels in the Asia-Pacific region are converging. Projections of livestock productivity are made and incorporated in a modified GTAP model. The consequences for regional and global trade in livestock and grains products are explored.  相似文献

Isolated single‐month, one‐off export transactions (observed once in a 49‐month window) turn out to be the dominant spell length in granular firm–product–destination trade data. Moreover, on average, for an export‐active firm, such one‐off events generate a significant part of foreign sales. These patterns cannot be explained by the lumpiness of trade (e.g., seasonal shipments), nor do they sit well with available trade models. To reconcile theory with the data, we introduce passive (i.e., unsolicited buyer‐side driven) exporting in addition to proactive exporting. Our empirical investigation establishes novel stylized facts on firm and destination characteristics associated with one‐off exporting.  相似文献

This paper addresses the issue of the development of Non-Governmental Organizations (NGOs) and the problem of how to combine sustainable outcomes from activities with sustainable organizations. It seeks to blend concept with practice via the development and application of a model of the NGO as an entrepreneurial organization. The context is that of the experience of (and work undertaken with) the Deutsche Gesellschaft fur Technische Zusammenarbeit (GTZ) funded Competency-based Economies through the Formation of Enterprise (CEFE) Network of NGOs in South Africa. The paper argues that viewing NGOs as entrepreneurial small organizations with a focus upon dynamic stakeholder network development, entrepreneurial management, strategic business development, and strategic alliance building is the key to the much sought after combination of sustainable outcomes and organization. After briefly reviewing some of the advantages and disadvantages associated with the role of NGOs in small enterprise development and the context of the operation of the CEFE Network of NGOs in South Africa, a model of entrepreneurial NGOs is proposed and then applied to South African CEFE Networks. In the conclusion a final outline of NGO sustainability criteria is offered and implications for donor approaches are briefly explored.  相似文献

This paper addresses welfare effects from trade liberalization in a Melitz ( 2003 ) heterogeneous‐firms trade model including the empirically important per‐unit (i.e., additive) trade costs in addition to the conventional iceberg (i.e., multiplicative) and fixed trade costs. The novel contribution of the paper is the result that the welfare gain for a given increase in trade openness is higher for reductions in per‐unit (additive) trade costs than for reductions in iceberg (multiplicative) trade costs. The ranking derives from differences in intra‐industry reallocations and, in particular, from dissimilar impacts on the number of exporters (i.e., the extensive margin of trade).  相似文献

This paper investigates the international asset allocation effectsof time-variations in higher-order moments of stock returnssuch as skewness and kurtosis. In the context of a four-momentInternational Capital Asset Pricing Model (ICAPM) specificationthat relates stock returns in five regions to returns on a globalmarket portfolio and allows for time-varying prices of covariance,co-skewness, and co-kurtosis risk, we find evidence of distinctbull and bear regimes. Ignoring such regimes, an unhedged USinvestor's optimal portfolio is strongly diversified internationally.The presence of regimes in the return distribution leads toa substantial increase in the investor's optimal holdings ofUS stocks, as does the introduction of skewness and kurtosispreferences.  相似文献

There has been a marked tendency to interpret the recent transformation of international migration systems in Eastern Asia in terms of a ‘migration transition’ model. The transition in these countries from net emigration to net immigration, with major inflows from poorer adjacent countries, is seen as being driven by an intricate regional pattern of uneven development but growing economic integration. This paper challenges this view through an examination of the trade, investment and migration linkages of the region’s four dragon economies (Hong Kong, Singapore, South Korea and Taiwan). It argues that the key influences on their international migration streams reflect, above all, the functions of these states as second-order, global city regions. Their place in the global capitalist system creates a shared demand for very particular types of both highly skilled and unskilled labour, but the migration policies of the four states are independently, and therefore distinctively, socially constructed. — Il y a une tendance à utiliser un modèle de ‘transition de migration’ pour interpréter les transformations récentes des systèmes de migration internationaux en Asie de l’est. La transition de l’émigration nette à l’immigration nette dans ces pays, avec des arrivées massives des pays adjacents plus pauvres, est supposée être due à un modèle régional complexe de développement inégal mais d’intégration économique croissante. Cet article questionne ce modèle et examine les liens entre le commerce, l’investissement, et la migration dans les quatre économies dragons de la région (Hong Kong, Singapour, la Corée du sud et Taï?wan). Il soutient que les influences majeures sur leur flux de migration internationale reflète avant tout les fonctions de ces états en tant que régions urbaines globales de deuxième ordre. Leur place dans le système capitaliste global crée une demande pour un type très particulier de travailleurs qualifiés et non qualifiés, mais les politiques de migration des quatre états sont indépendemment, et donc distinctement, socialement construites.  相似文献

ABSTRACT

The market orientation construct has proven to be of value to profit-seeking firms. It ought to be of value to NGOs too. Some previous research has been done to facilitate understanding of market orientation in NGOs, but the methodologies used have mostly been quantitative, and nothing is known about the market orientation of Chinese NGOs. To address this research gap, a qualitative case study methodology was used to develop a deeper understanding of how market orientation is practiced among NGOs in Hong Kong (China). Mapping with previous studies, the research found that three factors together explained the varying degrees of market orientation in the NGOs studied: senior management factors, organizational and institutional factors, and structural and system factors. But more importantly, an NGO’s funding base was found to moderate the relationship between these antecedents and an organization’s market orientation. The more that the NGO relies on public funding or a small number of funders the weaker the influence of the antecedents on market orientation. The more that the NGO relies on private funders, a diversified group of funders, or self-funding, the stronger the influence of the antecedents on market orientation, and the closer its understanding of market orientation is likely to be to that of a commercial entity. The article finishes with a substantive theoretical model for market orientation in the Chinese NGO context.  相似文献
