Gender and productivity differentials in science

The paper presents the results of an examination of gender differences in scientific productivity on a sample of 840 respondents, half the young scientific population in Croatia. In the last decade gender differences in the scientific productivity of young researchers have increased, which may be the result of introducing a more competitive scientific system. Young female researchers publish an average of two scientific papers less than their male counterparts in five years, and their publications reach 70.6% of males´ publication productivty in the same period. In the case of both sexes, about 15% researchers publish about half of all research papers, but even the most productive women publish less than their male counterparts. Socio-demographic, educational and qualificational predictors contribute more or less equally to the number of scientific publications by women and men. It is not until we introduce structural variables that a strong sex differentiation appears because these factors are much more powerful in explaining the production of women. They show that female scientists' publication productivity is more strongly influenced by their position in the social organization of science. There are also considerable sex differences in the case of individual productivity predictors. International contacts determine the number of papers by female scientists most of all. Attendance at scientific conferences abroad is the most powerful predictor of male productivity, too, but reviewing colleagues' papers and academic degree are also very important
