The Effects of Search-Related and Purchase-Related Mobile App Additions on Retailers’ Shareholder Wealth: The Roles of Firm Size,Product Category,and Customer Segment

Mobile channel additions have been shown to increase consumer-brand relationships, brand satisfaction towards and overall purchasing from a retailer, but what is less apparent is whether shareholders are fully rewarded for retailers’ mobile channel additions. Results from an event study on 115 announcements relating to mobile app additions of publicly traded U.S. retail firms between 2009 and 2016 indicate that the stock market responds generally positively to mobile app additions, but specifically to the two mobile app addition types. Stock market responses to search-related and purchase-related app additions are moderated by firm size, product category, and target customer age. For announcements of search-related apps, the market responds more positively to product retailers than to service retailers, and to small firms than large ones. For announcements of purchase-related apps, the market responds less positively to firms that target younger customers than firms who do not especially target them.     

销售渠道风险管理

本文首先建立了一套用以评估销售渠道风险的指标体系，通过建立企业各销售渠道的物元模型，运用物元的可拓性，将销售渠道的建设和管理控制的指标量化，按照统一规范化运算，得出便于比较的优度，从而对各类渠道风险进行排序选择风险最底的渠道。最后，本文以一个算例对评估销售渠道风险模型进行了实证研究。     

基于银行流动性管理视角的宏观审慎与货币政策协调研究

本文从商业银行流动性管理视角出发,探究银行微观主体行为如何影响宏观审慎与货币政策的协调。我们借鉴净稳定资金比例的设计理念,将商业银行的流动性管理行为纳入传统理论模型,刻画出两种流动性管理行为对货币政策信贷传导渠道效率的潜在影响及传导路径。在此基础上,采用我国50家商业银行2012年第1季度—2018年第2季度面板数据进行实证检验。我们发现,银行为提升长期流动性水平而进行的优化信贷资产结构的行为,能够显著提高货币政策传导效率。但是,部分净稳定资金比例较低的股份制银行和城市商业银行调整非信贷资产结构的行为则有可能降低货币政策传导效率。因此,在执行既有流动性监管措施的同时,关注与引导银行资产结构调整方式,对增强宏观审慎与货币政策的协调大有裨益。     

Delivery leadtime and channel structure decisions for make-to-order duopoly under different game scenarios

We develop game-theoretic models to explore the quoted delivery leadtime, price, and channel structure decisions for a make-to-order duopoly system under three game scenarios. Under the integrated-manufacturer first scenario, we find that (i) decentralization of the supply chain increases quoted leadtime; and (ii) both manufacturers may choose different channel structures under symmetric duopoly. By comparing with the symmetric scenario and the retailer first scenario, we find that a manufacturer facing a decentralized rival adopts decentralization when leadtime sensitivity, leadtime cost, and price elasticity are very small; the effect of decentralization on quoted leadtime largely depends on game scenario.     

Does retail type matter? Consumer responses to channel integration in omni-channel retailing

A critical issue faced by marketing practitioners today is orchestrating strategies that provide a smooth consumer experience in an omni-channel environment. The extant literature offers limited guidance on managing the consumer journey in an omni-channel environment across different retail types. Using the S–O-R framework as its basis, this study generates novel insights by examining how different types of retailers influence consumer perceptions of channel integration (CPCI) as well as consumer empowerment, trust, satisfaction, and patronage intention. Data from 736 consumers was collected using purposive sampling to target those who interact with retailers from high-end specialty stores, department stores, and hypermarkets. The data was then analysed using partial least squares structural equation modelling (PLS-SEM). We find that consumers from high-end specialty stores, hypermarkets, and department stores have different perceptions when patronising the omni-channel retail business. The implications of the study are discussed and suggestions for future research are presented.     

Understanding the role of situational factors on online grocery shopping among older adults

This paper seeks to identify the situational factors that drive the adoption of online grocery shopping among older adults. A two-step research process is employed. First, exploratory qualitative research is carried out to identify situational factors that older adults take into account when deciding whether to buy groceries online. This is followed by a conjoint experiment to determine which situational factors are considered most important when making such a decision. The sample consisted of 9 participants in the in-depth individual interviews and 206 respondents in the conjoint experiment. The findings indicate that health, mobility issues, and distance to a store are the most important situational factors driving older adults to buy groceries online. Moreover, the findings confirm that the adoption of online grocery shopping among older adults is a result of a complex trade-off of situational variables. The findings contribute to managerial practice by providing online grocery retailers with insight that can be applied when designing promotional programs targeted at older adults.     

金融服务实体经济的效率及影响因素研究 ——基于商业银行资产负债的实证分析

本文首先深入分析了商业银行的资产负债管理行为,构建商业银行追求利润的资产负债管理模型,从理论上分析出商业银行将资产配置到实体经济领域的影响因素。在此基础上,从金融监管的角度出发,将商业银行的资产负债项目进一步分类为杠杆类、通道类,利用25家商业银行2009到2018年的面板数据,实证分析针对商业银行的杠杆类、通道类资产负债的监管,对金融支持实体经济力度、价格的影响效果。结果显示：银行支持实体经济力度方面,银行的杠杆率对银行支持实体经济力度有显著正向效果,但是资金通道长度对银行支持实体经济力度的影响并不显著;银行支持实体经济的资金价格方面,杠杆率对银行资金价格的影响并不显著,但是通道长度则会显著增加资金成本;商业银行的国有、股份制、城商行性质对银行支持实体经济力度的影响也不显著,但是同等条件下,商业银行的国有性质会显著降低资金价格水平。     

The effect of capital requirement regulation on the transmission of monetary policy: evidence from Austria

This paper analyzes the role of banks’ regulatory capitalization in the transmission of monetary policy. We use a confidential dataset for Austrian banks spanning from the first quarter of 1997 to the fourth quarter of 2003. We find evidence that Austrian banks react in an asymmetric way to monetary policy depending on their regulatory excess capitalization, i.e. low capitalized banks react more restrictively to a monetary tightening than their highly capitalized peers.

跨境资本流动会加大金融波动吗?

日益活跃的跨境资本流动与金融波动的关系备受学术界关注,"国际风险承担渠道效应"的提出使人们开始重视金融中介在其中发挥的重要作用。本文基于全球79个国家1996-2017年的面板数据,采用系统GMM估计方法,考察了跨境资本流动对金融波动的影响,以及"国际风险承担渠道效应"存在与否。研究结果表明:大规模的跨境资本流动会增大金融体系脆弱性,加剧金融波动,对一国金融稳定造成强有力的威胁;跨境资本巨额的流出与流入均无助于金融稳定;跨境资本流动会通过影响金融中介的风险感知来改变其风险承担行为,最终会进一步放大跨境资本流动对金融稳定的负向作用,即存在"国际风险承担渠道效应"。因此,中国应坚持完善跨境资本流动管理体系与健全宏观审慎监管框架,严守资本充足率这一重要风险防线,加强对跨境资本和金融中介行为的监管,维护金融稳定。     

一种改进的基于DFT算法的MIMO-OFDS信道估计算法

本文提出了一种改进的DFT信道估计算法,首先将频域信道估计转换到时域,然后将时域中循环前缀长度之外的信道估计值置零。在此基础上,改进的算法要求对循环前缀之内,也就是n≤LG-1的信道估计值做进一步的处理,以便进一步消除噪声的干扰。通过计算机仿真验证了改进的DFT算法优于原算法。
