新能源汽车产业链企业的研发投入、政府补贴与企业价值

依据新能源汽车产业链企业2016-2020年面板数据,采用2SLS方法,考量研发投入对企业价值的影响,以及政府补贴在研发投入影响企业价值过程中的调节机制。结果显示：新能源汽车产业链企业研发投入对企业价值的影响为显著“U型”,政府补贴的调节引致研发投入与企业价值的“U型”曲线变得平缓。分样本研究发现,产业链上游和中游企业研发投入与企业价值均呈“U型”关系,下游企业研发投入与企业价值呈正线性关系,且政府补贴的调节效应各有不同。鉴于此,应当实行针对性和差异化的补贴政策提升补贴政策的成效,发挥“强链”带动“弱链”的作用实现产业链企业联动发展。

Post OPA-90 Vessel Oil Transfer Spill Prevention: The Effectiveness of Coast Guard Enforcement

Although oil spills from tanker accidents receive the most publicity, most vessel spills are not the result of accidents but of oil transfer activities. We investigate determinants of the size of vessel oil transfer spills as well as the effectiveness of Coast Guard enforcement activities in reducing their size. Vessel out-of-water and in-water oil transfer spillage functions are estimated utilizing tobit regression and detailed data on individual vessel oil transfer spills as well as Coast Guard safety/environmental enforcement activity data for the 1991–1995 period. Our estimation results suggest that Coast Guard hull but not machinery inspections are effective in reducing both out-of-water and in-water spills; patrols by air, but not by boat, are effective in reducing out-of-water spills; but neither is effective in reducing in-water spills. The results also show that the type of vessel (oil- and non-oil-cargo), vessel characteristics, vessel operations, weather/visibility conditions, and waterway type are determinants of post OPA-90 vessel oil transfer spills.

Macroeconomic Stabilization in the EMU: Rules Versus Institutions

This paper investigates the macroeconomic implications of different regimes of international fiscal coordination and monetary‐fiscal cooperation in a monetary union with independent fiscal authorities, that act strategically vis‐à‐vis a common central bank. In the presence of other policy goals than cyclical stabilization, such as interest rate smoothing and fiscal stability, we show that coordination among national fiscal authorities can reduce output and inflation volatility relative to the non‐cooperative setting in specific circumstances, as in case of demand disturbances, while turning potentially counterproductive otherwise. The adverse effects of union‐wide coordinated fiscal measures can be attenuated in a regime of global coordination, namely, when a centralized fiscal stabilization is coordinated with the common monetary policy as well.
