Farmers in the Vietnamese Mekong Delta face a wide range of climate-related and hydrological factors which threaten rice production. Smallholder farmers must adapt to climate change to sustain rice production as their central and most important livelihood activity. A sample was stratified across agro-ecological areas in the Delta affected by flooding, alluvial soils, acid sulphate soils, and saline water intrusion and by derived farmer typologies. A rural livelihoods approach was used in focus group discussions and in-depth interviews to identify and enumerate enabling and constraining adaptation factors. Smallholders experienced diverse natural hazards such as floods, abnormal rains, high temperatures, water scarcity, and salinity intrusion specific to the agro-ecological areas. Adaptation was constrained by labour shortages, water quality, topography, access to combine harvesters, transportation infrastructure, dryers and household savings. Adaptation was enabled by farming techniques and experience, cooperative groups, water quantity, access to information, and ability to purchase agro-chemicals through credit. Small farmers (< 1?ha) were more constrained than large farmers (> 1?ha) who had an expanded livelihood asset base. A range of policy implications are discussed, but adaptation is not just about technological fixes but requires overall improvements in a range of human, social and financial components. 相似文献
Using an instrumental variable quantile regression technique, this paper assesses whether country risk and financial uncertainty exert an impact on energy commodity futures prices under different commodity conditional return distributions over the period from January 1994 to July 2017. We also discuss whether the correlations change with different dimensions of country risk, that is economic, financial, and political. The results reveal that country risk and financial stress do have a significant impact on energy commodity returns of futures contracts with different maturities, but their direction, intensity, and significance differ, caused by the distinct market situations and divergent channels of country risk. 相似文献
Challenging anticompetitive acquisitions of nascent competitors is a top priority of the Antitrust Division of the U.S. Department of Justice. It is especially important that competition agencies remain vigilant of such acquisitions in platform markets, where indirect network effects and other market forces tend to preserve the status quo at the expense of smaller, more innovative rivals and potentially final consumers. This article discusses two such attempted acquisitions: (1) Visa’s acquisition of technology firm Plaid that threatened to disrupt Visa’s monopoly power in online debit; and (2) Sabre’s acquisition of Farelogix, which is a firm that allows airlines to connect directly to travel agencies and thereby disintermediates Sabre and other global distribution systems.
Empirical studies that examine the impact of democracy on foreign direct investment (FDI) assume that the relationship between democracy and FDI is the same for resource exporting and non-resource exporting countries. This paper examines whether natural resources in host countries alter this relationship. We estimate a linear dynamic panel-data model using data from 112 developing countries over the period 1982-2007. We find that democracy promotes FDI if and only if the value of the share of minerals and oil in total exports is less than some critical value. We identify 90 countries where an expansion of democracy may enhance FDI and 22 countries where an increase in democratization may reduce FDI. We also find that the effect of democracy on FDI depends on the size and not the type of natural resources. 相似文献
Since 1986, Vietnam has undertaken various reform measures in the trade and foreign investment area. This paper finds significant contributions of world trade, and competitiveness and liberalization effects to Vietnam's export growth over the period 1997–2008. Vietnam's exports became more competitive and better complemented the import demand of Vietnam's trade partners. In addition, dynamic comparative advantage became evident in many products, but significant room remains for improving export competitiveness. Foreign direct investment (FDI) inflows also increased and helped stimulate Vietnam's exports. FDI inflows have increased in both the short‐ and long‐term, yet are only of a limited magnitude. This necessitates more effective measures to enhance the linkages between FDI and domestic enterprises. 相似文献
This paper applies a disaggregated approach to segment industrial markets under competitive structures taking the air-freight market for the high-technology product industry in Taiwan as a case study. Data from firms is used to examine the structure of the air freight industry and we find that carriers are clustered into two strategic groups, express and forwarder. Pricing is a leading strategy recognized by customers for forwarders, whereas service punctuality and freight security are the winning strategies for express. The high-tech freight market is classifiable by shipment destination and size. 相似文献
This article proposes a novel valuation model, growth and value hybrid model, to estimate the stock price. This proposed model combines the essence of the asset-based approach, the income-based approach, and the principle of mean reversion to develop the theoretical closed-form formula consisting of three coefficients: value coefficient, value support coefficient and growth coefficient. Regression analysis is employed to fit market data to determine these coefficients. Moreover, this study proposes the double sorting method to build the quantile regression models of the formula to estimate the stock price at a specific quantile. The results show that the predictive capability of the hybrid valuation model is superior to the model without using value support coefficient, which supports the assumption that the PBR is not associated with the ROE when the ROE is less than a threshold. In different time periods of the stock market, no significant difference exists on the value support coefficient. However, the variations of the value coefficient and the growth coefficient are significant. 相似文献
This paper focuses on employee performance management (PM) to explore how multinational enterprises (MNEs) localise their human resources within their subsidiaries in a developing country. It uses qualitative research methods to examine four US and four Japanese MNEs operating in Vietnam. The paper identifies both home and host country effects as significant factors in the transfer of MNEs' PM policies and practices. The US firms emphasised financial and non-financial measurements and utilised a wide range of PM management tools and techniques. These techniques, despite being unfamiliar in Vietnam and possibly considered incompatible with Vietnamese culture, were transferred successfully to the Vietnamese subsidiaries. The Japanese firms' PM approach was characterised by a more informal form of regular performance review, within a strictly top-down process and which suffered from accusations of bias and lack of transparency by Vietnamese respondents. This paper argues that the transitional period in Vietnam from a centrally planned economy to a market-oriented one has made the national business system more receptive to new and seemingly contrasting practices. It provides no evidence to support the argument that transfer of practices is more likely, where the cultures of the countries involved are relatively similar. 相似文献
