Abstract
Purpose
It is widely accepted that coauthorship and collaboration promotes intellectual partnerships and improves the quality of publications. This paper examines the relationship between collaboration, productivity and publications in the field of family business.
Design/methodology/approach
The authors identify the most prolific authors, affiliations and countries and focus on the evolution of research in the field of family business. In doing so, the authors employ social network analysis to discover the structure of the networks and the ways in which authors, institutions and countries interact.
Findings
The empirical results show that collaboration is positively related to productivity, and there is significant evidence that the shaped networks exhibit small-world characteristics, a condition in which collaboration within authors becomes integrated in conjunction with time.
Practical implications
The findings highlight the mechanics of collaborative research production and can be useful to understand the importance of collaboration patterns to be followed in the field of family business.
Originality/value
The contributions are as follows: (a) application of social network analysis to model the coauthorship patterns among individuals, institutions and countries in family business; (b) distinguishing the most degree-central authors in the social network of collaborating academics; (c) investigation of the academic collaborations in family business that have the characteristics of a small-world social network and (d) suggesting a unique connection, through published keywords, between the research priorities of the most central or prolific authors with the research trends in the family business literature. The authors demonstrate that authors' collaboration becomes integrated in conjunction with time.

Abstract
Purpose
This study investigates the dynamic relationships among trading behaviors of different investor groups (foreigners, domestic institutions and domestic individuals), stock returns and sovereign CDS (Credit Default Swap) spreads in Korea.
Design/methodology/approach
We employ the VAR (Vector autoregression) model to examine the dynamic relationships between CDS spread changes, stock returns and investors' behavior in the stock market.
Findings
The CDS spread change (stock return) declines (rises) in response to shocks to net foreign flows into the stock market on the same day. Foreigners buy stocks more intensely one day after an increase in the stock return, but they do not respond to CDS spread changes. Domestic individuals trade in the opposite direction of foreigners in response to shocks to both stock returns and CDS spread changes on the same day. Positive net stock purchases of domestic institutions (individuals) predict positive (negative) stock returns and negative (positive) CDS spread changes next day.
Originality/value
This study extends prior studies by examining how different investor groups' trading behaviors in the stock market are associated with not only the stock market but also a closely related market (CDS market). Prior empirical studies on the relation between the stock and CDS markets do not pay attention to possible heterogeneity in trading behavior across different types of investors in the stock market.

Abstract
Purpose
This paper aims to examine whether private healthcare entrepreneurship can flourish and overcome obstacles in cases of a free-access public health system and periods of strict public policies, such as the COVID-19 pandemic. Moreover, the paper aims to illuminate the wider social role of private healthcare entrepreneurship during the COVID-19 pandemic.
Design/methodology/approach
This paper adopts a qualitative methodological strategy through 12 in-depth semi-structured interviews with the owners of diagnostic centres located in small Greek towns.
Findings
Private healthcare entrepreneurship flourished and played a significantly positive social role in the context of a degraded public health sector, which lacked investments for more than ten years and was further depleted by its recent focus on COVID-19 incidents. This paper reveals that although public policies that aimed to deal with COVID-19 produced serious consequences, business activity adapted to the new circumstances.
Research limitations/implications
Future research can combine the findings of this paper with the views of stakeholders, policymakers and social actors.
Originality/value
This paper's value lies in its efforts to expand our current knowledge regarding the impact of COVID-19 public policies on entrepreneurship.
