Some determinants of entry into the rapeutic drug markets

  • Sillrley S. Yu


This paper investigates empirically some determinants of entry into the U.S. pharmaceutical industry during the period 1964–1974. The statistical findings of the study are consistent with a priori expectations. Market growth is found to provide incentives for entry, Product differentiation, market concentration, and drug innovation are found to be significant barriers to entry into drug markets.
