汽车供应链广告策略博弈研究

新能源汽车的研发、市场投入使得现有的汽车品牌竞争愈演愈烈。为加强汽车供应链上下游间合作,首先提出汽车制造商在投入全国性广告费用的同时为零售商分摊地方性广告费用;其次,基于stackelberg博弈和纳什博弈模型,分别构造函数分析制造商最优的广告投入和分摊比例及零售商的最优广告投入并分析具体变量之间的关系。最后总结并提出汽车供应链上下游需建立信任关系,加强广告合作;制造商应合理决策广告分摊比例,实现自身与零售商双赢局面。     

考虑引流作用与定价权的网红直播带货定价策略分析

构建一个由制造商与零售商组成的二级双渠道供应链，其中制造商一方面为零售商供货，另一方面通过直播渠道销售产品。考虑到网红直播能够为线下零售引流，分别讨论网红主播有直播渠道定价权与制造商有直播渠道定价权两种情况下供应链成员最优决策问题。研究发现：在制造商拥有直播渠道定价权时，零售价格与直播渠道价格均高于网红主播拥有直播渠道定价权时的情景，制造商与网红主播谁拥有直播渠道定价权谁就在直播带货中更有利可图。当制造商拥有渠道定价权且选择头部主播进行带货时，零售商存在着“搭便车”的现象。     

Investment subsidies and redistributive capital income taxation in a neoclassical growth model

How do investment subsidies bear on pure redistribution when coupled with capital income taxes? In a heterogeneous agent, neoclassical growth framework it is found that on impact, with no optimizing behavior, investment subsidies are good for growth but bad for redistribution. The opposite holds for capital income taxes. But when the government acts as a Stackelberg leader vis-à-vis the private sector (the follower), the optimal feedback policy is by construction time-consistent and implies that in a long-run optimum the tax scheme does not distort accumulation. This holds regardless of social preferences. For the feedback Stackelberg equilibrium I find that (pure) redistribution can go either way and capital income taxes are nonzero in the long-run, time-consistent optimum, depending on the social weight of those who receive redistributive transfers, the distribution of pretax factor incomes, and the intertemporal elasticity of substitution. It is argued that investment subsidies may be an important indirect tool for redistribution, and may allow for the separation of “efficiency” and “equity” concerns.     

中国式分权、社会资本与农村公共服务满意度

将财政分权体制与社会资本纳入农村公共服务供给的考察范畴，重点关注了中国式分权背景下不同维度社会资本对农村公共服务满意的调节效应。基于中国式分权的Stackelberg博弈模型证实了民生类支出偏好对村民具有较高的福利效应，社会资本不仅对提供者存在正向溢出渠道，还显著提升了村民福利。利用CGSS数据的实证结果表明：在考虑县级政府普遍面临财政困境的前提下，宽松的财政约束实际抑制了农村公共服务满意度提升，与正式制度存在替代关系的社会资本则显著提升了村民对公共服务的满意度。尽管如此，仍需警惕过度密集的网络嵌入所表现出的负向调节作用。以上结论通过分群回归和稳健性检验被证实是有效可信的，从而为纠正农村民生公共品供给偏向，补齐新时代农村公共服务短板提供了有益借鉴。
