We shift the usual perspective of strategic trade policy – the 'third market setup' – to the 'home market' framework in order to reconsider the consequences of government (in)ability to precommit to its policy and compare these findings with those analogous from the 'third market setup'. In addition, we also analyze how robust the sign is of particular policy instruments (R&D subsidies) within the home market setup, as opposed to the third market setup, when there is a shift from 'second–best' to the 'first–best' policy.
