Retail internationalization: A review and directions for future research

Abstract

The purpose of this article is to provide a review of scholarly articles that have examined retail internationalization issues. We identify three core areas within RI research: (1) RI drivers and impediments, (2) RI strategy, and (3) RI performance. We also discuss four RI strategy issues that have been examined: (1) RI speed, (2) Foreign market selection, (3) Foreign entry mode, and (4) Strategy employed. Based on the review, we point to multiple areas where RI research is lacking and can contribute to the advancement of the field as well as offer insightful implications for international retail managers.     

Clinical characteristics,treatment patterns,and socio-economic burden of COPD in Bulgaria

Background: While the impact of COPD in Western-Europe is known, data from Eastern-Europe is scarce. This study aimed to evaluate clinical characteristics, treatment patterns, and the socio-economic burden of COPD in Eastern-Europe, taking Bulgaria as a reference case.

Methods: A representative sample of Bulgarian patients with COPD was randomly chosen by pulmonologists, based on the following inclusion criteria: COPD diagnosis with at least 1 year of living with COPD, ≥40 years of age, and use of COPD medication. Patient characteristics, treatment, quality-of-life, healthcare resource use, and costs were systematically assessed.

Results: A total of 426 COPD patients were enrolled. Approximately 69% were male, 40% had occupational risk factors, 45% had severe and 11% had very severe COPD. Mean CAT scores were 13.80 (GOLD A), 21.80 (GOLD B), 17.35 (GOLD C), and 26.70 (GOLD D). Annual per-patient costs of healthcare utilization were €579. Yearly pharmacotherapy costs were €693. Indirect costs (reduced and lost work productivity) outnumbered direct costs three times.

Conclusions: Bulgaria has relatively high percentages of (very) severe COPD patients, resulting in considerable socio-economic burden. High smoking rates, occupational risk factors, air pollution, and a differential health system may be related to this finding. Eastern-European COPD strategies should focus on prevention, risk-factor awareness, and early detection.     

Performance of International Retailers: Empirical Evidence of an S-Curve Relationship

The performance outcomes of retail internationalization have attracted considerable scholarly interest, but studies have offered differing perspectives and findings on this relationship. In an effort to fill this gap on the topic, we posit that the relationship between the degree of retail internationalization and performance exhibits an S-curve shape. Using a sample of 18 international retailers with operations on six continents for the period 2001–2015, we find evidence of the S-curve dynamic where international retailers tend to experience declining performance after initial expansion beyond the home market, improving performance with continued expansion, and declining performance with further international expansion. We also examine two moderating variables on this relationship—foreign market growth and store format diversification. Our findings show that foreign market growth reinforces the hypothesized S-curve relationship while store format diversification reverses it. We offer theoretical and managerial implications based on the results of our study.
