The purpose of this study is to provide an overview of the economic and clinical impacts of direct‐to‐consumer (DTC) advertising on consumers and physicians.

Controversy around the benefits and concerns associated with DTC advertising are summarized. The sources are sorted based on their position toward DTC promotions: defending or opposing. Two recent works by Woloshin et al. and by Weisseman et al. are discussed in depth to provide the empirical evidence for the impacts of DTC promotions.

Notwithstanding many concerns against DTC advertising, evidence‐based papers report that both consumers and physicians are potentially benefited from it. Consumers rate the health‐related information contained in DTC advertising as important. Physicians do not feel that they are pressured to prescribe inappropriate medications driven by DTC advertising. Physicians perceive improved communication and education among DTCA‐influenced patients. However, consumers tend to overestimate drug effectiveness when the ads vaguely convey the benefit information and subsequently, seek unnecessary treatments. DTC advertising needs to be required to demonstrate the benefit information using actual data. This will help consumers avoid overuse of drugs.

This paper recognizes DTC advertising as a positive force for the public health and at the same time identifies its potential negative effects on the economic and clinical aspects of the health care markets. This can offer practical help policymakers develop the effective regulations on DTC advertisings to reinforce the beneficial outcome while attenuating the potential harms that might take place.

This study aims to address how the social structure of the hospitality management field has evolved from 1960 to 2016.

The informal social structure of the hospitality management literature was analyzed by collecting authorship data from seven hospitality management journals. Co-authorship analyses via network analysis were conducted.

According to the findings, throughout the history of hospitality management, international collaboration levels are relatively low. Based on social network analysis, the research community is only loosely connected, and the network of the community does not fit with the small-world network theory. Additional findings indicate that researchers in the hospitality management literature are ranked via degree centrality, closeness centrality and betweenness centrality. Cliques, which contain at least five researchers, and core researchers are identified.

This study helps both scholars and practitioners improve the informal structure of the field. Scholars must generate strong ties to strengthen cross-fertilization in the field; hence, they collaborate with authors who have strong positions in the field. Specifically, this provides a useful performance analysis. To the extent that institutions and individuals are rewarded for publications, this study demonstrates the performance and connectivity of several key researchers in the field. This finding could be interesting to (post)graduate students. Hospitality managers looking for advisors and consultants could benefit from the findings. Additionally, these are beneficial for journal editors, junior researchers and agencies/institutions.

As one of the first study in the field, this research examines the informal social structure of hospitality management literature in seven journals.
