Online Price Search: Impact of Price Comparison Sites on Offline Price Evaluations

Consumers increasingly rely on Internet price comparison sites (PCS) to gain knowledge about the market. The prices generated by a PCS search can act as contextual reference prices and influence the attractiveness of prices encountered later as consumers shop offline at local stores. This paper demonstrates that both PCS retailer ratings and the shape of the PCS price distribution influence the impact of PCS search results on later price evaluations. A favorable PCS retailer rating increases the perceived validity of the price associated with that retailer, enhancing the impact of that PCS price on offline price evaluations (Study 1). The shape of the PCS price distribution can also influence later price evaluations, however this effect depends on the information provided by the PCS retailer ratings. When PCS retailer ratings are similar, implying similar validity for the associated prices, low PCS prices and those appearing more frequently in the PCS price distribution have more impact (Studies 2 and 3). When PCS retailer ratings are variable (some high and some low), the PCS price distribution effect occurs only when the PCS retailer ratings provide congruent information about price validity — that is, the most frequent price is offered by retailers with more favorable ratings. Study 3 shows that price validity inferences do mediate this result. Finally, we depart from the offline shopping context to show that when consumers choose a retailer directly from the PCS search results, the effect of PCS retailer ratings is stronger for high-priced retailers and for consumers who rely less on the retailer price as a heuristic to infer retailer service level. Based on our findings we offer insights for online and offline retailers when considering strategic responses, such as price matching guarantees.     

Resources for business resilience in a COVID-19 world: A community-centric approach

COVID-19 has drawn renewed focus on the importance of resilience, both among practitioners and in academia, as companies struggle to cope with the rapid swings, changing patterns, and disruptions in supply and demand. This article identifies and delineates a way forward for companies to support resilience, particularly recognizing the wider communities they are nested in and the resources that exist there. To identify such productive resources, known as capitals, we provide a novel and actionable integrated capitals framework (ICF). ICF integrates 10 existing frameworks drawn from both practice and academia and is comprised of nine different forms of capital that businesses can leverage and contribute toward supporting resilience. We provide insights into how businesses can use this framework to achieve resilience through this useful, yet underutilized, path.     

Institutional distance among country influences and environmental performance standardization in multinational enterprises

This research compares and contrasts the findings in Aguilera-Caracuel et al. (2013) with the outcomes of applying fuzzy-set qualitative comparative analysis (fsQCA) — a methodological strategy that gathers quantitative and qualitative information to explain complexity at the case level and generality across cases. Using the same sample of 128 multinational enterprises (MNEs) with headquarters and subsidiaries based in the USA, Canada, France, and Spain, we identify a set of relevant configurations of causes and conditions to explain environmental performance standardization. By avoiding separate treatments for each variable, which is typical in multiple regression analysis (MRA), we overcome prior limitations and propose a new way of understanding this phenomenon. In summary, our results significantly reinforce and complement the previous results.     

Product specialization in international trade: A further investigation

In an influential paper, Schott [Schott. Peter K. (2004). “Across-product versus within-product specialization in international trade.” Quarterly Journal of Economics, 119 (2): 647–678] makes two empirical observations about U.S. imports. (1) The United States is increasingly sourcing the same product (however narrowly defined) from both developed and developing countries. That is, ‘across-product specialization’ has been decreasing. (2) The unit values of these multiple-sourced products are positively and significantly correlated with the capital and skill abundance of exporters and with the capital–labor ratios used by exporters. That is, endowments-driven ‘within-product specialization’ has been increasing. We show that both these observations extend to the imports of Brazil, India and Japan. However, our main finding is that observation (1) is largely driven by two factors. First, China is the dominant low-wage exporter of multiple-sourced products. Second, the most developed countries remain the primary exporters of multiple-sourced products. The U.S. case is the most extreme of our four importers: When China is deleted from the U.S. import data there is no trend in across-product specialization and rich exporters are increasing their trade share of multiple-sourced products. Since deleting China has no theoretical justification, these results must be viewed not as a contradiction of Schott's work but as a way of deepening our understanding of his empirical results.

Pricing a rural development program: uncertainty,indifference, and protest behaviors

This article presents an econometric approach to modeling uncertainty, unwillingness to pay, and protest behavior in contingent valuation studies. For that purpose, a mixture model with sample selection is developed for a multiple‐bounded uncertainty elicitation format. The proposed theoretical framework is applied to evaluate the social welfare impact of implementing a sustainable rural development program. Results show that a “naive” analytical approach that excludes protesters from the analysis would result in significantly higher willingness to pay estimates for those individuals who favor the implementation of the program and agree to reveal their true reservation prices.     

Microenterprises and multiple bank relationships: The case of professionals

The present paper focuses on professionals as a special group of microenterprises. It explains their characteristics and financial relationships, using data from a survey conducted in Germany in 2002. Consistent with the theory of asymmetric information and relationship lending, we find that these firms maintain a small number of bank relationships, which increases in firm size and age. They tend to choose multiple banking relationships to overcome credit rationing and finance larger loans. Credit risk and the structure of the banking market do not seem to matter.     

Multiple store patronage: The effects of store characteristics

The present study contributes to the literature on multiple store patronage in two important directions. First, it examines whether consumers׳ perceived importance of store characteristics have effects on multiple store patronage. Second, it examines the relationship between multiple store patronage and consumers׳ share of wallet at the primary store. Our results show that consumers who attach high value to sales promotions are more likely to visit multiple stores. However, store characteristic factors generally did not exert significant effect on multiple store patronage. Furthermore, we find that multiple store patronage and share of wallet are not interdependent and the profiles of consumers in terms of them do not share many common characteristics.

人力资本与企业绩效关系的实证分析

国内外对企业绩效的实证研究主要是研究财务指标与企业绩效的关系,缺少对非财务指标的实证研究特别是人力资本与企业绩效关系的实证研究。本文选取反映人力资本的指标和反映企业绩效的指标,随机选取上市公司的数据进行多元回归分析,结果发现,员工高学历比例和员工专门技术人员比例,与企业绩效存在显著关系。笔者建议,要明确企业绩效与人力资本的关系,重视人力资本的作用,同时要结合行业特点和竞争程度综合考虑企业绩效。
