Expatriate social capital

Social capital is the product of human interactions and relationships, which occur between individuals and social networks. Therefore, it can be summarized as the shared links, understandings and values that allow individuals and groups to trust each other, and therefore, to work with each other in society.

In the case of expatriation—the process through which an individual lives and works in a country other than their country of citizenship, often temporarily and for work reasons —, social capital has been identified as an important factor for expatriate career success, performance, cultural and psychological adjustment, and international knowledge transfers, among other topics.

General definitions of social capital
Given the long history of the social capital concept, a range of definitions have emerged over the years, especially since the topic gained more prominence in the 1990s. Still, the most cited definitions in 2019 belonged to Pierre Bourdieu, Robert Putnam, Nan Lin, James Coleman, and Janine Nahapiet and Sumantra Ghoshal. The table below shows some of the definitions these authors put forward:

Social resources theory
According to social resources theory, there are a number of resources embedded in a person's social network and social ties, including material goods and intangible items—for instance, trust, values, or status. In this way, individuals can benefit from their social ties and use them as resources when they are able to receive information and support through them to achieve certain goals and objectives.

Expatriate social capital is distinct from other forms of social capital because it usually involves social connections across a range of different countries. Additionally, it has especial relevance for International Human Resource Management (IHRM) because it can be viewed as a resource, not only useful for expatriates themselves, but also for the multinational companies and enterprises (MNCs and MNEs) employing them.

Business expatriates
Historically, the use of the term expatriate has been inconsistent and varied. For this reason, it is important to know that IHRM concerns a specific type of expatriate: the business expatriate. According to McNulty and Brewster, who argued that a concise and universal definition should be adopted, business expatriates are “legally working individuals who reside temporarily in a country of which they are not a citizen in order to accomplish a career-related goal, being relocated abroad either by an organization, by self-initiation or directly employed within the host-country”.

Organizational knowledge benefits of expatriate social capital.
Needless to say, individuals can share their resources with others. In the case of expatriates, they can transfer the knowledge they earned through their social resources during international experiences to the organizations they work for. As a result, organizations can leverage expatriate social capital to improve inter-unit learning inside the firm, learn about external business opportunities, train other personnel (such as future expatriates and/or leaders) and gain a competitive advantage in the international economy.

Transfer of inpatriate and repatriate social capital
For instance, if an inpatriate (a kind of expatriate who is from a foreign country, but is transferred from a foreign subsidiary to the corporation's headquarters; Harvey, Novicevic and Speier, 1999) has large social networks in the host country, it will be positively related to firm-specific learning.

Similarly, research carried out with expatriates after an international assignment (usually called repatriates) also suggests that the benefits of the social ties developed abroad exceeds the period of the assignment, facilitating knowledge flows across units in an organization.
