需求不确定对单周期产品的生产商—零售商供应链的影响

在单周期产品的生产商—零售商的供应链中,由于市场存在着激烈的竞争,市场需求的不确定性必然会对供应链双方的决策产生很大的影响。借助传统的报童模型,建立Stackberg博奕模型,考虑了一个供应商面对两个不同零售商时的情景,分别分析了当零售商决策依据是最大化期望利润和当两零售商的市场需求相关时,以及在零售商的决策依据是在给定利润水平时最大化其概率的情况下,市场需求不确定会对供应链双方产生怎样的影响。     

偏差分析下供应链可持续性合作的绩效研究

为探讨供应链中制造商、供应商和顾客之间的可持续性合作对可持续性绩效、市场绩效的影响,本文搜集有关供应链企业的300份有效调查问卷,利用结构方程模型,以回归分析、信度和效度检验为基础的路径分析方法实证检验供应链合作理想模型的偏差对可持续性绩效、市场绩效的不利影响。研究结果表明,供应链参与者可持续合作积极性和企业内部可持续生产的积极性集成对绩效结果影响很大,可持续供应链合作需在一定框架下结合各方积极参与才能提高绩效。     

虚拟集群式旅游供应链模型构建研究

文章基于旅游供应链理论研究动态与现代信息技术发展态势,提出以信息拉动式为特征的在线旅游供应链(e-tourism supply chain)的理念。从集群式供应链视角,分析了虚拟集群式旅游供应链建立的动因,构建了虚拟集群式旅游供应链理论模型。文章通过创新旅游供应链研究视角,借鉴产业集群与供应链管理耦合研究理论,试图在赛博空间(Cyberspace)里,构建起虚拟集群式旅游供应链的理论框架,可分成4个部分:(1)旅游者信息链,是围绕着每个旅游者需求信息的一条"信息拉动式供应链",在此基础上形成旅游企业旅游服务大规模定制链;(2)旅游服务定制链,旅游企业在以"旅游者"为中心的信息链上提供即时响应、即时采购、即时生产、即时销售的敏捷制造服务,同业性旅游企业合作服务于旅游者;(3)信息共享平台,包括旅游者需求汇集、统计、分流平台,旅游企业沟通平台和旅游评价平台;(4)专业化辅助企业,具有弹性专精的优势,缓解大规模标准通用化服务提供和市场的定制化随机要求(stochastic demand)之间的矛盾,满足了旅游者对定制化旅游服务需求。

我国货币供给内生性研究——基于现金漏损率的分析

货币供给内生性与外生性问题是一个重要的理论和现实问题,正确判断一个经济体的货币供给内外生性对于认识货币供给运行机制、制定正确的货币政策以及提高货币政策的有效性都具有重要意义。本文以现金漏损率为切入点,深入分析其对货币乘数、进而对货币供给量的影响,并得出我国货币供给内生性增强的结论。最后,在该结论的指导下,为我国选择正确的货币政策以及如何提高货币政策的有效性提出了若干建议。     

Why do commercial banks hold government bonds? The case of Japan

We investigate the determinants of the demand for Japanese government bonds (JGBs) by commercial banks in Japan. In particular, by estimating portfolio equations for JGB demand and bank loans, based on a panel data set from the late 1990s to the 2000s, we rigorously test the popular assertion that the long stagnation of the real economy caused a shift in the portfolios of commercial banks from bank lending to JGBs. We find that the popular assertion is not empirically supported. Rather, the portfolio shift from loans to JGBs has been caused by a fall in the ratio of the loan rate to unit lending costs, or the bank’s price–cost margin for lending.     

Supply‐ versus Demand‐Side Policies in the Presence of Carbon Leakage and the Green Paradox

We consider a climate coalition that seeks to reduce global emissions in the presence of carbon leakage and resource exhaustibility. We show that a credible announcement of future unilateral supply‐side policies delays foreign emissions, and we derive the optimal combination of consumer taxes and producer taxes when we consider leakages from free riders, both within periods and across periods. The tax shares generally differ over time. A decline in the present value of the social cost of carbon over time supports a time path where the consumers’ tax share of the total carbon tax also declines over time. We illustrate our findings with a numerical model.     

Modeling asymmetric price transmission in the European food market

In this study, we employ a multivariate panel error correction model (PVECM) to investigate asymmetric price transmission among the farm, processor, and retail segments of the European food supply chain for the 2005–2016 period. The results indicate that, in both the long- and short-run, retail prices respond more strongly to processor price increases than decreases and the same occurs for processor prices due to farm price changes. Thus, the findings demonstrate the presence of positive asymmetric price transmission in the European food supply chain. Finally, the results of the present study indicate that the food price pass-through varies greatly across product category and across countries, and that the pass-through to producer prices is greater than that to consumer prices.     

Interrelationship between crude oil and the stock markets of major demanders and suppliers in emerging and developed markets

This paper investigates the time-varying relationship between the stock markets of advanced and emerging oil-exporting and oil-importing countries and the international crude oil price indices. The results reveal that the time-varying among the oil-exporting and oil-importing countries responds similarly to aggregate supply- and demand-side effects. Oil-exporting countries have a slightly higher integration with the oil markets, while oil supply shocks have a slightly higher impact on emerging oil-exporting countries. The oil markets exhibit a lower time-varying relationship with the Asia-Pacific oil-importing markets, which indicates those markets may be attractive to investors during periods of turbulence in the oil market.
