The aim of this paper is to offer a comprehensive overview of the field of international human resource management (IHRM) research by tracing its evolutionary development over a 24-year period. The study seeks to understand how the field has progressed by considering historical research themes and their subsequent integration into more recent scholarly work, thereby identifying current and emerging research trends.

This paper employs bibliometric analysis to examine the evolutionary path of IHRM research from 1995 to 2019. A dataset of 1,507 articles from journals specializing in IHRM, international business and general management was created. Analysis at the keyword, thematic and network levels was conducted to identify trends, historical context and the interrelatedness of research themes.

The analysis reveals that IHRM research has gone through several phases of thematic focus, from initial emphasis on cultural differences and expatriate management to more recent topics like global talent management and digital transformation. Earlier research themes continue to be incorporated and re-contextualized in modern scholarship, highlighting the field’s dynamic nature.

This paper is one of the first to use a bibliometric approach to systematically examine the evolution of IHRM research. It not only provides a historical perspective but also outlines future research trends, incorporating the institutional logic perspective. The findings offer deep insights that are valuable for researchers, practitioners and policymakers interested in the development of IHRM research and its practical implications.

This chapter discusses how firms can accrue unique advantages from their foreign status in the host country, with a particular focus on informal networks. Drawing on the literature on the liability and asset of foreignness, this chapter argues that foreign firms can be in a better position to balance between the bright and dark side of informal networks than local firms. Foreign firms can deviate from local isomorphic pressures to minimize potential involvement in negative sides. Moreover, they can build more instrumental informal networks in which the dark side of informal networking is better controlled and regulated without losing social cohesion, flexibility, and other benefits of the bright side. This chapter contributes to our understanding of how foreign firms can turn foreignness into assets from liabilities when managing their informal networks in the host country.

This paper assesses the informational contents of open electronic limit order book in KOSPI 200 index futures market spanning sample period from December 2004 to November 2005 with a particular focus on the incremental information contained in the limit orders behind the best bid and offer. Using Vector Error Correction Method to estimate ‘Information share’ of quotes as suggested by Hasbrouck (1995), we find that the order book is significantly informative–its contribution to price discovery is approximately above 70%, while remaining is from cash price. Furthermore, we find the limit orders from step 2 to 5 is more informative than the best bid and offer in price discovery process, based on the estimation of information share. This empirical finding sharply contradicts the evidence suggested by previous literature that the best quotes contribute the most to price discovery and the contribution of order book the beyond the best bid and offer is marginally additional in cash market. Summarizing overall empirical evidence, limit order book in KOSPI 200 index futures market plays a differential role in contrast with stock markets.

Prior literature on online customer reviews (OCRs) suggests that individuals are socially influenced by information shared by others. Given that the online environment brings together users from different cultures, understanding how users differ in their processing and generation of OCRs across cultures is imperative. Specifically, this paper explores how cross-cultural differences influence OCR generation when there are inconsistencies between recent and overall review ratings.

The authors employ an empirical study and an experimental approach to test the predictions. For the empirical study (Study 1), the authors collected and analyzed actual review data from an online hotel review platform, Booking.com. This was followed by an experimental study (Study 2) in which the authors manipulated the thinking style represented by each cultural orientation to further explain how and why cross-cultural differences exist.

The results show that compared with the review ratings of users from collectivist cultures, those of users from individualistic cultures are more likely to follow recent review ratings. Based on the experimental study, the authors further find that such cross-cultural differences in OCR generation are driven by differences in thinking style.

This research extends the literature by demonstrating the cross-cultural differences in individuals' herding tendencies in OCR generation. The authors also add to the literature by showing in which direction OCR herding occurs when there is a discrepancy between overall and recent review ratings. From a managerial perspective, the findings provide guidelines for online platforms serving the global market on predicting customers' OCR generation and constructing appropriate response strategies.

To identify sources of the success and failure of COVID-19 control measures and develop best-practice public health policy in mitigating the spread of COVID-19, this paper aims to evaluate the efficiency of various combinations of government COVID-19 control measures among OECD countries. This paper also identifies which factors critically influence the efficiency of COVID-19 control measures.

This paper employed two-stage network SBM (slacks-based measure of efficiency) models with variable returns-to-scale and constant returns-to-scale, respectively, among various forms of data envelopment analysis (DEA) models. As a post hoc analysis, the authors used Tobit regression for examining the causal relationship between a nation's cultural dimensions and its COVID-19 control measure's efficiency scores.

The authors found that the pervasive less individualistic and higher uncertainty avoiding culture positively influenced the efficient control of COVID-19 outbreaks since such a culture helped the government impose its mandatory COVID-19 control measures without people's strong resistance to those measures.

Many public health policymakers are wondering why COVID-19 control measures are not effective in coping with the COVID-19 outbreaks. This paper helps the government find the most efficient combination of COVID-19 controls measures for curbing the spread of the stubborn coronavirus. This paper is one of the first attempts to identify pandemic risk mitigation factors from a cultural perspective.

Many online review sites, such as TripAdivisor.com, encourage review posters to upload a profile photo to improve the perceived reliability of online reviews. This study aims to examine the roles of reviewer profile photos in the online review generation and consumption processes.

Data were collected via Amazon MTurk. Two experimental studies were conducted. Study 1 had a sample size of 106 respondents. In Study 1, this paper examined the role of a reviewer profile photo in the online review generation process. Study 2 had a sample size of 482 respondents. In Study 2, this paper examined the role of a reviewer profile photo in the online review consumption process under two different circumstances, namely, comprehensive and incomprehensive review text.

The findings show that reviewer profile photos play different roles when consumers generate online reviews versus when they consume reviews. In the review generation process, reviewers are more likely to upload a profile photo to improve the credibility of their reviews. On the other hand, in the review consumption process, reviewer profile photos do not contribute to an increase in the perceived review helpfulness.

If the readers have difficulty processing the review content, review profile photos play a critical role in determining perceived review helpfulness. This study provides both theoretical and managerial implications by indicating how reviewer profile photos play different roles in online review posting and consuming behavior.

The ongoing impact of COVID-19 and the subsequent perception of threat have shifted consumer perceptions and evaluations of service experiences. This paper aims to investigate how customers’ service evaluation is shared as customer reviews following the pandemic and the heightened perception of threat. In doing so, this research particularly investigates the shifts in the textual contents of online reviews.

This study used the textual contents in the online reviews posted on Hotels.com for 1,497 hotels in New York City for empirical analysis. In total, 109,190 observations were used for the analysis.

By analyzing actual online review data from an online review platform for hotel services, this study finds that the text reviews generated after the pandemic outbreak tend to contain words with stronger negative emotions. In terms of the pronoun choice, this study further finds that the use of “I” increases while the use of “we” decreases.

This research adds to the existing literature on service evaluation and online customer reviews by showing that there are shifts in the expressions used to communicate service evaluation through online text reviews, including the degree of emotionality and pronoun usage. Because potential customers are likely to rely on online reviews for their own decisions, the findings suggest that it is important for practitioners to be aware of such shifts and respond accordingly.

This study aimed to empirically examine the effectiveness of disclosing user comment history without disclosing personal identity as a nudge policy to refrain users from posting malicious content online.

The authors collected the number of comments and posters from the leading portal website in South Korea, Naver.com. To causally investigate the impacts of the new nudge policy on the number of comments and posters, the authors used the regression discontinuity design (RDD) approach.

The authors found that the new policy reduced all types of comments, including the number of malicious comments, self-deleted comments and current comments. This resulted in an overall decrease in the total number of posted comments, which is considered a side effect. In addition, the authors found that the effect of the nudge policy, which disclosed user comment history, has a stronger effect on older female users than their counterparts.

The study findings extend the current knowledge on a nudge policy being implemented by a website as a means to reduce malicious online content and how it impacts user content posting behaviors.

Studies that investigate the length of stay as a predictor of consumer post-purchase behavior are rare despite its importance in efficient hotel management. By analyzing online customer reviews, this study aims to fill this gap in the extant literature on the relationship between length of stay and customer satisfaction level.

The authors collected and used online review data on hotels in London for this study. A series of linear regression analyses were conducted to examine the effect of length of stay on customer satisfaction as measured by review ratings. The authors used the Mahalanobis matching approach to confirm the empirical findings.

This analysis shows that length of stay is negatively associated with customer satisfaction. Additionally, the authors find that this negative relationship is stronger in high-end hotels than in low-end hotels.

The research findings contribute to the literature by shedding light on a new stream of research, namely, length of stay. Additionally, the research findings offer novel insights that could help hotel managers understand the trade-off between longer stays and customer satisfaction.

To the best of the authors’ knowledge, this is one of the first few studies to show the systematic impact of length of stay on the valence of online review ratings, as well as the moderating effect of hotel levels by analyzing customer online reviews on hotel experiences.
