Infrastructure provision and international market share rivalry

The paper examines a model of strategic infrastructure investment. Two oligopolistic firms compete on home and foreign product markets for market shares. The national governments support the firms in the market rivalry by providing cost reducing public infrastructure services that are financed out of taxing an input used in the production process. It is shown, that infrastructure policy can be used as an instrument for strategic trade policy. However, governments are facing the problem of balancing the burden of taxation and the benefits of infrastructures. The theoretical model also raises some critical issues with respect to the policy relevance of recent empirical infrastructure research.

Outsourcing and trade in a spatial world

This paper provides an analysis of outsourcing and trade in a spatial model à la Hotelling. In this setting, we discuss the trade-off between transport-cost-related disadvantages and outsourcing-related production cost advantages of a large economy and we investigate how the existence of national transport costs influences both the structure of industrial production and the pattern of final goods trade. In addition, the model gives a rich picture of the possible welfare effects of trade liberalization. In particular, we show that a final goods exporting country definitely gains from economic integration, while a final goods importing country may lose. Finally, when lowering domestic outsourcing activities, trade liberalization may reduce world welfare, even if pro-competitive effects lead to a decline in consumer prices.     

Trade matters except to war neighbors: The international stock market reaction to 2022 Russia’s invasion of Ukraine

We investigate the role of international trade and proximity to war in international stock markets during the invasion of Ukraine by employing DiD designs and panel data comprising 70 stock markets. We find that differences in trade exposure to warring countries (trade effect) have a substantial and negative impact on non-European equity markets but are irrelevant for European markets. In contrast, differences in the distance to warring countries (proximity effect) have a significant and negative impact on European markets but have no bearing on non-European markets. We find that the relevance of rent from mineral, natural gas, and oil resources and the relevance of metals, ores, and fuels in exports operate as mitigators of the trade effect. Our paper provides valuable empirical evidence regarding the importance of mitigating the vulnerability of financial markets to international trade when a major war breaks out.     

农机服务规模经营对粮食生产效率的影响机理研究

依据2009—2019年全国31个省（自治区、直辖市）的省级面板数据,运用随机前沿分析方法和Tobit模型,考量农机服务规模经营对粮食生产效率的影响及其作用机理。结果显示：2009—2019年,中国粮食生产效率总体递增,但区域间发展不平衡;农机服务规模经营通过技术引入效应和劳动力替代效应提高粮食生产效率,其中,技术引入效应的发挥受限于农业研发支出水平及其增速,劳动力替代效应在农业劳动力成本高的区域发挥的影响效用更佳。鉴于此,应加快农业科技创新,发展粮食生产全程机械化服务,完善农机社会化服务体系。     

发展我国私人银行业务的若干思考

私人银行是指以财富管理为核心、面向社会富裕人士提供的一种个性化高端金融服务,其显著特点是根据客户需求提供量身定做的金融服务,并保证私密性.我国财富管理市场潜力巨大、需求极其旺盛,且中资银行在私人银行业务方面拥有比较优势,发展我国私人银行业务的前景广阔.但是,发展我国私人银行业务也面临着诸如服务理念落后、产品狭窄、专业人才匮乏、管理信息系统滞后等诸多制约因素.因此,我国银行业应营造正确的金融服务和金融消费理念,推进业务综合化、拓展金融产品,构建高效的人才机制和信息管理系统,加强与有丰富私人银行经验的外资银行的战略合作,以促进私人银行业务的发展.
