We develop a model of induced innovation where research effort is a function of the death rate, and thus the potential … innovation based on differences in disease prevalence across population subgroups (i.e. race). Our model yields three empirical … population as a whole, induced innovation leads to growth in mortality disparities between minority and majority groups. Using …
