This paper gives evidence to a stylized fact often disregarded in international trade empir-
ics: countries' diversification. In the last fifteen years, the growth of world trade coexisted
with the tendency of countries to reduce the specialization of their export composition
along the development path. On average, countries do not specialize, they diversify. Our
semiparametric empirical analysis shows how this result is robust to the use of different
statistical indexes used to measure trade specialization to the level of sectoral aggrega-
tion and to the level of smoothing in the nonparametric term associated to income per
capita. Using a General Additive Model (GAM) with country-specific fixed-effect, we show
that, controlling for countries heterogeneity, sectoral export diversification increases with
income.
