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.

关于韩非法治思想与现代法律的思考

针对先秦儒家的"德治"主张,韩非提出了"法治"理论.韩非的法治思想其实质是君主专制与国家(政府)集权,它与现代法治所倡导的民主与法制精神相悖.但这种"国家(政府)法治"传统却被我们自觉或不自觉地因袭了下来,成为我国经济改革深化和转变政府职能的巨大障碍.为了建立一个好的市场经济,防止滑入一个坏的市场经济,法治应该由国家统治社会和民众的工具变为保护社会和民众的工具,进而成为社会和民众自我保护的工具.法律应该由君主专制的利器变为社会和民众捍卫民主与自由的盾牌.     

中部省份在国家经济发展战略西移中崛起的若干思考

国家经济发展战略西移将对我国区域经济发展格局产生非常显著的影响。对中部省份而言，机遇与挑战并存。中部省份在全国经济发展中所处的地位、全国性的经济技术转移、地区产业结构调整与升级要求等，使得中部省份有条件在国家经济发展战略西移过程中迅速崛起。中部省份必须营造良好的发展环境，加快基础设施建设，积极调整产业结构，选择培育经济发展极，调整与完善各项政策，积极探索区域经济合作的新模式等，以实现中部与西部地区的共同发展。     

Regional, national, and spatially explicit scenarios of demographic and economic change based on SRES

We report here spatially explicit scenario interpretations for population and economic activity (GDP) for the time period 1990 to 2100 based on three scenarios (A2, B1, and B2) from the IPCC Special Report on Emissions Scenarios (SRES). At the highest degree of spatial detail, the scenario indicators are calculated at a 0.5 by 0.5 degree resolution. All three scenarios follow the qualitative scenario characteristics, as outlined in the original SRES scenarios. Two scenarios (B1 and B2) also follow (with minor adjustments due to scenario improvements) the original SRES quantifications at the level of 4 and 11 world regions respectively. The quantification of the original SRES A2 scenario has been revised to reflect recent changing perceptions on the demographic outlook of world population growth. In this revised “high population growth” scenario, A2r world population reaches some 12 billion by 2100 (as opposed to some 15 billion in the original SRES A2 scenario) and is characterized by a “delayed fertility transition” that is also mirrored in a delayed (economic) development catch-up, resulting in an initially stagnating and subsequently only very slow reduction in income disparities. The spatially explicit scenario interpretation proceeds via two steps. Through a combination of decomposition and optimization methods, world regional scenario results are first disaggregated to the level of 185 countries. In a subsequent second step, national results are further disaggregated to a grid cell level, taking urbanization and regional (rural–urban) income disparities explicitly into account. A distinguishing feature of the spatially explicit scenario results reported here is that both methodologies, as well as numerical assumptions underlying the “downscaling” exercise, are scenario-dependent, leading to distinctly different spatial patterns of population and economic activities across the three scenarios examined.
