Despite this trend, the optimal product-line selling mode for both manufacturers and online platforms remains ambiguous. This study aims to address this uncertainty by developing an analytical model. In this model, a manufacturer offers a product line consisting of two quality-differentiated products. Concurrently, an e-tailer (online platform) provides both the first-party and third-party modes, catering to consumers with heterogeneous preferences for product quality. The analysis reveals that when the high-quality product's quality level is sufficiently low, the manufacturer achieves maximum profit by wholesaling the high-quality product with the first-party mode but directly selling the low-quality product via the third-party mode; otherwise, the manufacturer maximizes profit by directly selling both products via the third-party mode. For the e-tailer, when the high-quality product's quality level is moderate, he can gain the highest profit by encouraging the manufacturer to wholesale both products with the first-party mode. However, when the high-quality product's quality level is sufficiently low (high), the e-tailer can obtain the highest profit under the case where the manufacturer sells the high-quality product via the third-party (first-party) mode but distributes the low-quality product with the first-party (third-party) mode. The intuition lies in the competition dynamics and the double marginalization effect under different selling modes.</p></div>","PeriodicalId":48402,"journal":{"name":"Journal of Retailing","volume":null,"pages":null},"PeriodicalIF":8.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142161505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We advance knowledge by investigating the interplay between political ideology, variety seeking, and crisis-induced threats using a large-scale dataset of over 32 million U.S. grocery transactions before and during the initial wave of the COVID-19 pandemic, as well as county-level voting results. In doing so, we seek to answer three questions: (1) How does political ideology influence variety seeking under normal conditions? (2) How do crisis-induced threats influence variety seeking? and (3) How does political ideology influence variety seeking under crisis-induced threats? Our findings reveal that, under normal conditions, conservatives show greater variety seeking than liberals. Yet, during crisis-induced threats, conservatives decrease their variety seeking, whereas liberals increase theirs. These results complement existing studies that, using lab experiments and surveys, have identified various mechanisms––oftentimes competing––that influence variety seeking. We advance this work with externally validated and robust empirical evidence on how consumers’ variety seeking behaviors change substantially during crisis-induced threats versus normal conditions. These insights provide retail practitioners with marketing-relevant insights and strategies, tailored to the political composition of their consumer base, that can enhance their crisis preparedness and responses.</p></div>","PeriodicalId":48402,"journal":{"name":"Journal of Retailing","volume":null,"pages":null},"PeriodicalIF":10.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0022435924000162/pdfft?md5=e4414a86057d9cbd32ca698f51487357&pid=1-s2.0-S0022435924000162-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140779563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study provides initial insights into the evolution of the effectiveness of different website attributes and heterogeneity in their effects. Using a rich data set, spanning vastly different contexts and time periods, the authors detect new, evolving patterns by which different website attributes relate to customer loyalty. Experience-related attributes have become more important than efficiency-related attributes in recent years, with some noteworthy contingencies, such that they are especially impactful for services (vs. products) and in cultures with long-term (vs. short-term), high (vs. low) self-indulgence, and high (vs. low) masculinity orientations. The increasing importance of experience-related attributes is driven by cultures with a low (vs. high) uncertainty avoidance. These insights in turn offer practical implications for retailers navigating the challenges associated with designing their websites to drive customer loyalty.</p></div>","PeriodicalId":48402,"journal":{"name":"Journal of Retailing","volume":null,"pages":null},"PeriodicalIF":10.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0022435924000150/pdfft?md5=f54666d46263e8f1fedd0a11bf781c85&pid=1-s2.0-S0022435924000150-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140787716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study seeks to determine which autonomous stores are most likely to succeed. By adapting convenience theory and drawing on secondary and qualitative data, the authors identify unique features of autonomous stores that constitute convenience dimensions: options for check-in (access convenience), staff support (assistance convenience), check-out (transaction convenience), and to allow customers to check their itemized baskets (verification convenience). Perceptions of convenience, autonomy, and safety explain the influences of unique store features. A conjoint experiment provides a test of the direct effects of each dimension on store patronage and indirect effects through convenience, autonomy, and safety perceptions. The results indicate that, with the exception of check-out, consumers prefer staffed stores; having to check in (e.g., with a credit card), limited access to (remote) staff, and an inability to verify the basket before payment represent significant barriers. In turn, some trade-offs arise: Store features that increase convenience and autonomy undermine safety perceptions. Finally, community-based and rural locations are better suited for autonomous stores than anonymous traffic hubs.
