Research has been conducted regarding how demographic diversities are related to internationalization, however, it tend to focus on outcomes such as firm performance, instead of degree of internationalization. This research adds a new dimension to this field of research by investigating whether TMT resilience work as a mediator in this relationship.

The purpose with this thesis is to explain what relationships demographic characteristics such as gender, age, cultural and tenure diversity, but also faultlines have on TMT resilience and degree of internationalization. Because of the positivist and deductive approach a cross-sectional research design was used. The method was quantitative and came in the form of archival data and secondary data.

The findings shows that culture is positively related to TMT resilience, and TMT resilience is partially related to the degree of internationalization.

 The limitations are the number of respondents in the secondary data varied a lot from the different TMTs, and that there is a risk that they misinterpreted the questions, this can potentially affected the resilience variable in the tests. The implications are that in listed international firms, gender and age diversity appear to not be related to the degree of internationalization.

The original value of the conducted study is that new insights regarding how the degree of internationalization of a firm is related to certain demographic diversities in TMTs.
