Employee brand engagement on social media: Managing optimism and commonality

This article considers how employees engage with B2B firms on social media, a topic that is largely overlooked in the extant brand engagement literature. Using the results from a large-scale study of employee brand engagement on social media, we identify two key drivers of employee brand engagement using the content analysis tool DICTION—namely, optimism and commonality. Employees of top-ranked and -rated firms express higher levels of optimism and commonality in their reviews of their employers on social media than do their counterparts in bottom-ranked and -rated firms. This permits the construction of a 2 × 2 matrix that allows managers to diagnose strategies for increasing or improving employee brand engagement. This creates four different kinds of employee brand engagement situations, and offers human resources and marketing managers different strategies in each case. We demonstrate how practitioners and scholars can shed new light on the way stakeholders engage with brands.     

Consistency and Recovery in Retail Supply Chains

Practitioners and researchers describe inventory service level with metrics that communicate the likelihood of demand fulfillment without considering the ongoing capabilities of the supplier, for example, in‐stock and fill rate. We develop a method for measuring inventory service level that incorporates such supplier capabilities, namely consistency (the ability of a supplier to fulfill orders repeatedly) and recovery (the ability of a supplier to fulfill orders after a lapse in service). Using data from two retail supply chains, we illustrate our approach. To demonstrate the impact of consistency and recovery on supply chain performance, we model a retailer purchasing from competing suppliers with different levels of consistency and recovery. The model incorporates the retailer's uncertainty about demand and the retailer's uncertainty about its suppliers' service levels. We characterize how the retailer's orders and profitability change with a supplier's delivery performance through numerical experiments calibrated with field data. We find notable differences in market share across suppliers with similar traditional inventory service level metrics but differences in consistency and recovery. Further, we observe that a retailer can increase its profitability by determining orders via consistency and recovery in lieu of common metrics like in‐stock. Given the influence of consistency and recovery on supply chain outcomes, we discuss implications for practice and future research.     

Retail formations: tracing the fluid forms of an online retailer

ABSTRACT

Change has often been said to characterise retailing, and research on retail change is extensive. However, though much of that research has focused on retail formats, it has not sufficiently addressed the fluid nature of retailing and how its formats emerge. This paper offers a more dynamic conceptualisation of retail format change by introducing the concept of retail formation. Taking a constructivist market studies approach and drawing upon an ethnographic study of a Swedish consumer electronics retailer, the paper shows how retail formations are continually being made in a dynamic process that can be initiated by various actors, does not necessarily follow a logical order, and commonly produces unexpected results. The concept of retail formation allows us to better understand the increasing fluidity of retailing enabling us to trace complex market processes, examine multiple actors simultaneously, and taking into account the socio-historical and socio-cultural dynamics involved in shaping retail markets.     

Factors predicting attitude toward disclosing personal data online

To test a theoretical model, this study explores the effect of anxiety, trust, personality, and perceived benefits on the disclosure of personal information online. An online survey conducted among participants in the United States (n = 248, age range: 20–82 years) examined attitudes toward disclosing personal data online. Specifically, the study researches the impact of anxiety disclosing personal data, trust (both in the Internet and in institutions), the Big Five personality traits, and four sets of perceived shopping benefits (opportunity, bargain, purchase, and expected privacy benefits) in e-commerce disclosure and their role as antecedents for adoption and use of e-commerce. The study aligns with existing trust literature and corroborates other findings on how perceived purchase benefits impact individuals’ attitudes toward disclosing personal data online. The data suggest that both trust in the Internet and trust in institutions positively influence attitude toward disclosing personal data online. Perceived purchase benefits were also significant positive predictors for attitude toward disclosing personal data online. Furthermore, personality dimensions can affect attitude toward disclosing: the more neurotic a person is, the more negative their attitude is about disclosing personal data online. The study underscores that consumers have a responsibility to educate themselves about online disclosure and marketing practices, and about how to protect their online privacy. Most importantly, fostering trust, reducing anxiety, and promoting benefits are essential to the future of e-commerce. Implications for theory, consumers, marketing practice, and public policy are also discussed.     

双边政治关系、制度质量与中国对外直接投资*

本文利用中国与其他国家在联合国大会决议的投票行为作为双边政治关系的代理变量,以中国对89个国家2003—2015年对外直接投资数据为样本,分析了双边政治关系对中国对外直接投资的影响。研究表明：整体而言,中国的对外直接投资会受到双边政治关系的显著影响,政治关系的亲密有利于中国对外直接投资的增加。东道国制度质量可以降低中国对外直接投资对双边政治关系的敏感度,且制度质量的调节只能在中国对比自己制度质量高的国家投资时发挥作用。以2008年为分界点,后危机时代双边政治关系对投资的影响更加显著,双边政治关系的经济效应也会显著地受到东道国制度质量的调节。此外,中国改善与“一带一路”沿线国家的政治关系,可以促进中国的对外直接投资。     

Clinical and economic benefits of professional CGM among people with type 2 diabetes in the United States: analysis of claims and lab data

Background: It is estimated that one in 10 people in the US have a diagnosis of diabetes. Type 2 diabetes accounts for 95% of all cases in the US, with annual costs estimated to be $246 billion per year. This study investigated the impact of a glucose-measuring intervention to the burden of type 2 diabetes.

Objective: This analysis seeks to understand how professional continuous glucose monitoring (professional CGM) impacts clinical and economic outcomes when compared to patients who are not prescribed professional CGM.

Methods: This study utilized a large healthcare claims and lab dataset from the US, and identified a cohort of patients who were prescribed professional CGM as identified by CPT codes 95250 and 95251. It calculated economic and clinical outcomes 1 year before and 1 year after the use of professional CGM, using a generalized linear model.

Results: Patients who utilized professional CGM saw an improvement in hemoglobin A1C. The “difference-in-difference” calculation for A1C was shown to be –0.44%. There was no statistically significant difference in growth of total annual costs for people who used professional CGM compared to those who did not ($1,270, p?=?.08). Patients using professional CGM more than once per year had a –$3,376 difference in the growth of total costs (p?=?.05). Patients who used professional CGM while changing their diabetes treatment regimen also had a difference of –$3,327 in growth of total costs (p?=?.0023).

Conclusion: Significant clinical benefits were observed for patients who used professional CGM. Economic benefits were observed for patients who utilized professional CGM more than once within a 1-year period or who used it during a change of diabetes therapy. This suggests that professional CGM may help decrease rising trends in healthcare costs for people with type 2 diabetes, while also improving clinical outcomes.     

Trade-creation and trade-diversion effects of regional trade arrangements: low-income countries

Although the number of regional trade arrangements (RTAs) among the lowest-income developing countries is surging, the literature on their welfare effects is still scarce, and the few that exist fail to provide conclusive results. Furthermore, these RTAs are dominated by countries with a small share of total exports destined for intraregional trade flows. Our study focuses on the welfare effects of RTAs (pertaining to trade creation and trade diversion) among this group of countries. We use a theoretically justified gravity model to estimate welfare effects, focusing on trade creation and trade diversion and deviating from the norm in related studies, accounting for heterogeneity in third countries. Using ECOWAS as a sample, we estimate welfare effects on 1992–2012 annual bilateral imports for 14 countries from 169 countries. Contrary to conventional expectations in the literature, we find that economic integration among small and relatively low-income countries that have a small share of total trade with each other is welfare-improving for the members as a group, for the majority of the individual member countries, and for some third countries. Accounting for heterogeneity in third countries reveals that an RTA among low-income countries has a particularly robust trade-creation effect.

An Equilibrium Selection Theory of Monopolization

We develop a duopoly model in which firms compete for the market (e.g., investing in process innovation or product development) as well as in the market (e.g., setting quantities or prices). Competition for the market generates multiple equilibria that differ in the firms’ investment levels, relative size, and profitability. We show that monopolization that affects competition in the market can act as an equilibrium selection device in competition for the market. In particular, it eliminates equilibria that are undesirable for the monopolizing firm, while not generating new equilibria. This result complicates the task of determining whether a firm's dominance in a given market is the result of fair competition or unlawful monopolization. We discuss a number of implications for antitrust policy and litigation, and illustrate these by means of two well‐known antitrust cases.
