Note, per capita it looks like most of the countries studied are discovering new drugs (in the study's terminology "new molecular entity") at much faster rate than the United States when adjusted for population.
The money quote:
" Our data suggest that the United States is important but not disproportionate in its contribution to pharmaceutical innovation. Interestingly, some countries with direct price control, profit control, or reference drug pricing appeared to innovate proportionally more than their contribution to the global GDP or prescription drug spending"
Denmark is so tiny compared to the US, it hardly makes sense to compare drug discovery per cápita. If Denmark happens to release just a single extra drug one year, it totally shifts their ratio.
