The emergence of a mass market for electric vehicles (EVs) offers development opportunities for countries that have abundant resources of cobalt, nickel, lithium, copper, aluminium and manganese. Not surprisingly, developing countries have proposed ambitious plans to expand production of these raw materials. However, an observation from the resource curse literature is that strong institutions are required if they are to mitigate the risk of poorly directed, often excessively procyclical, investment, not least because of the complexity, opacity and price volatility of many raw materials utilised by global EV value chains. This paper examines the outlook for EV demand and associated raw material usage paying attention to the drivers and sensitivities required to assess and track future market transformations. These end use shifts are then placed in the context of the broader supply chain adjustments and trends shaping the demand. For resource exporters, adapting to structural change will require fiscal, regulatory, environmental and institution reforms designed to capture shifting patterns of resource wealth in a way which takes appropriate account of comparative advantages in specific value chains and mitigates adverse environmental and social consequences from their extraction and processing.  相似文献

The use of the internet is growing rapidly and has become an engine for economic development. However, few studies have examined the impact of internet use on agricultural production, and the results are not yet conclusive. Employing a dataset of more than 2000 observations in rural Vietnam, our study analyses the impact of internet use on agricultural productivity using the heteroscedasticity-based instrument approach suggested by Lewbel, Journal of Business and Economic Statistics, 2012, 30, 67–80 and examines the heterogeneity and distribution of the impact using quantile regressions. Our results show that internet use has significant and positive effects on agricultural productivity. However, these effects are heterogeneous across population groups. The positive effects of internet use are stronger for households with a lower level of education, with a young and female head, and from ethnic minorities. The benefits are also found to be skewed towards the group of farmers at the bottom of the productivity distribution. Therefore, we propose facilitating the diffusion of the internet, since it not only boosts agricultural productivity, but also reduces productivity inequality. In addition, we recommend promoting rural education, supporting local markets, investing more in irrigation systems, and facilitating farm mechanisation as these factors are found to contribute to increasing agricultural productivity.  相似文献

This paper aims to analyse how employment and wages change when a firm's trade status is altered. Using a detailed firm-level dataset of Vietnamese manufacturing enterprises, the study finds that how firms trade matters for firm employment and wages in Vietnam. The average effect of one-way trading (exporting or importing) is positive for both firms' total employment and female employment. Direct trading activities are associated with a higher level of employment than indirect trading activities by firms. The female employment effect of direct exports is nearly three times higher than direct imports. Indirect imports hurt firms' total employment and female employment. Both direct and indirect two-way traders experience higher growth in firm employment than direct-only traders. However, it is interesting to note that indirect two-way trading activities have a positive impact on female employment. Furthermore, the commencement of direct import is also associated with greater labour cost advantage.  相似文献
