In order to improve economic growth, many governments use public policies to
promote their countries? degree of internationalisation. When designing
optimal public incentive schemes for internationalisation it is fundamental
to consider the characteristics of export markets, such as size, competition
degree, tax system, and product differentiation. This paper analyses whether
product differentiation has any impact on optimal internationalisation
incentive policies, focusing on export subsidy schemes. We develop a
two-stage game for three different scenarios: (1) no subsidy, (2) a
fixed-subsidy scheme, and (3) a subsidyper-quantity-exported scheme. Using
numerical analysis, we revisit the analysis of schemes designing optimal
public incentives for internationalisation and conclude that for export
markets with low product differentiation a subsidy-per-quantity exported
scheme is best at stimulating internationalisation, while for export markets
with high product differentiation a fixedsubsidy scheme is the preferable
policy.
