Japanese distribution system: The impact of newly designed collaborations on wholesalers' performance

In January 1995, the Kobe earthquake devastated a major part of Kobe's distribution infrastructure. Apart from the expected complaints about lost sales, wholesalers reported some surprising comments after the reopening. Wholesalers stressed the advantages of newly designed distribution channels, especially the opportunity to end longstanding business relationships known as keiretsu. This study is concerned with the recent development of vertical collaboration in the Japanese distribution channel. Multiple regression analysis revealed that the supplier's service to wholesaler, the supplier's offerings to the wholesaler, and buyer's service to the wholesaler did contribute to the enhancement of the performance of the wholesaler. The three factors explained 16% of the wholesaler's performance. The regression analysis also showed that the wholesaler's intra-logistics activities contributed to the improvement of the performance of the wholesaler and explained 5% of its performance.     

流转税改革是否优化了国民收入分配格局？

本文在考察新一轮财税改革基础上,根据1995～2013年省际数据,运用面板向量自回归（PVAR）模型,考察“营改增”对我国国民收入分配格局的影响。研究结果表明,基于“营改增”视角的新一轮财税改革优化了国民收入分配格局,一方面,流转税改革提高了居民和企业部门在国民收入分配中的所得份额;另一方面,流转税改革降低了政府部门在国民收入分配中的所得份额。同时,重点考察了“营改增”对国民收入分配格局变动的贡献程度。最后,依据本文的计量分析结果,提出优化国民收入分配格局的政策建议。     

产权分离与产权分割——职务发明国防专利权归属的新思路

权利归属是国防专利制度的核心问题,发明人的核心利益是智力成果收益问题。当前,国防领域职务发明权利归属不清,违背了智力财产私权性的法律原则,造成的结果是发明人失去了产权,国家损失了国防专利制度可能带来的收益,解决问题的关键是跳出"非此即彼"的权利归属思维定势,将国防专利权分为所有权、使用权、收益权和处置权,并在此基础上进行权利分割。国家拥有所有权,发明人拥有使用权和处置权,国家、单位和发明人共同拥有收益权,这既体现了法律的公平正义,又符合经济规律,做到了权、责、利相统一。     

Specialization dynamics

This paper proposes a new empirical framework for analyzing specialization dynamics. A country’s pattern of specialization is viewed as a distribution across sectors, and statistical techniques for analyzing the evolution of this entire distribution are employed. The empirical framework is implemented using data on 20 industries in seven OECD countries since 1970. We find substantial mobility in patterns of specialization. Over time horizons of 5 years, this is largely explained by forces common across countries, including world prices and common changes in technical efficiency. Over longer time horizons, country-specific changes in factor endowments become more important. There is no evidence of an increase in countries’ overall degree of specialization.     

Why parallel trade may raise producers' profits

This paper shows that a manufacturer may benefit from parallel trade. In addition to an intuitive condition about the effect of demand shocks, this occurs when competitive retailers must order inventories before they know the realization of demand and for products whose sale value drops at the end of the demand period. For these types of products, letting retailers trade unsold inventories generally results in larger orders placed with the manufacturer and higher manufacturer profit. The model provides a simple explanation as to why the volume of parallel trade is now very large and accepted by manufacturers for some products such as automobiles, clothes, toys, consumer electronics, musical recordings, cosmetics and perfumes.     

Closed-form Bayesian inferences for the logit model via polynomial expansions

Articles in Marketing and choice literatures have demonstrated the need for incorporating person-level heterogeneity into behavioral models (e.g., logit models for multiple binary outcomes as studied here). However, the logit likelihood extended with a population distribution of heterogeneity doesn’t yield closed-form inferences, and therefore numerical integration techniques are relied upon (e.g., MCMC methods). We present here an alternative, closed-form Bayesian inferences for the logit model, which we obtain by approximating the logit likelihood via a polynomial expansion, and then positing a distribution of heterogeneity from a flexible family that is now conjugate and integrable. For problems where the response coefficients are independent, choosing the Gamma distribution leads to rapidly convergent closed-form expansions; if there are correlations among the coefficients one can still obtain rapidly convergent closed-form expansions by positing a distribution of heterogeneity from a Multivariate Gamma distribution. The solution then comes from the moment generating function of the Multivariate Gamma distribution or in general from the multivariate heterogeneity distribution assumed. Closed-form Bayesian inferences, derivatives (useful for elasticity calculations), population distribution parameter estimates (useful for summarization) and starting values (useful for complicated algorithms) are hence directly available. Two simulation studies demonstrate the efficacy of our approach. JEL Classification C6 · C8 · M3     

外商直接投资行业分布对中国能源消费影响的实证分析

运用指数因素分析法将中国各行业能源消费指数分解为外商直接投资（FDI）数量效应、FDI行业分布效应和投资能源强度效应，拟揭示FDI行业分布对中国能源消费的影响。研究认为，FDI行业分布对中国能源消费影响较大并呈现加强态势。因此，通过制定合理的产业政策引导FDI的行业分布，可以有效地降低中国能源消费。     

中美双边工业品增加值贸易隐含碳福利核算与分配问题研究

现代贸易方式不仅导致贸易利益在全球价值链上进行分配,还带来了贸易隐含污染排放在全球贸易网络中的分布。两国之间的贸易利益分配除了表现为贸易经济福利的分配,还表现为贸易隐含碳福利的分配。本文将贸易增加值分解法结合MRIO模型对2000—2014年中美双边工业品贸易增加值所隐含的碳福利分配及影响机制展开深入分析。研究结果表明:(1)在中美双边工业品增加值贸易隐含碳福利分配中,碳福利逆差在中国,碳福利顺差在美国;(2)中美工业品贸易碳福利级差经历了“先扩大,后收窄”的过程,美国次贷危机之后双边碳福利不平衡状况重新呈现扩大趋势;(3)中国碳排放强度下降、价值链地位提升以及对美进口规模扩大都有助于改善碳福利逆差的局面,但美国对中国不断扩大的中间品和最终品需求以及双边复杂的技术关联结构仍是中国碳福利逆差的主导因素;(4)全球价值链的深化可能将导致对出口国加征关税会通过降低进口消费侧排放的方式恶化加征国的贸易隐含碳福利。本文研究的时间范围同时覆盖中国加入WTO以及美国次贷危机两个重要节点,这对于重新审视中美经贸关系新格局下双边贸易隐含碳福利分配构建了一个新的分析视角,为中美未来贸易谈判以及全球碳排放责任认定提供了一个新的解读方向。     

中国经济双循环耦合协调度分布动态、空间差异及收敛性研究

研究目标:测算1999～2019年中国经济“内循环”与“外循环”耦合协调度的实际水平并分析其分布动态、空间差异及收敛性。研究方法:耦合协调度模型、Kernel密度估计、Dagum基尼系数及其分解法和β收敛模型。研究发现:考察期内,中国经济“内循环”与“外循环”之间的耦合协调度呈现稳定的上升趋势,但总体水平仍然较低,地区异质性、时间阶段性特征明显;空间差异持续扩大,主要来源是区域间差异;正空间相关关系持续而稳定;全国及四大地区经济双循环耦合协调度存在显著的绝对β收敛和条件β收敛过程,不同地区耦合协调度收敛位置的影响因素各不相同。研究创新:测算了中国经济双循环耦合协调度水平并分析其时空演进规律与收敛性。研究价值:对于总体把握我国经济双循环发展规律,因地制宜,精准施策,加快构建双循环新发展格局具有积极的现实意义。     

平均税率、标准税率与收入分布对个人所得税累进性的影响

运用中间累进性指标将个人所得税累进性的变化分解为标准税率的影响及收入分布的影响,对再分配效应变化也做了类似的分解,实证分析了我国2005~2011年个人所得税累进性及再分配效应的变化。结果显示,收入分布改变对于累进性的变化发挥主导作用,平均税率对于再分配效应的变化非常关键。因此,个人所得税的改革首先需要在分析居民收入分布的基础上进行,另外在累进性提高的同时也需十分关注税收规模的变化。
