The effect of pharmacies’ right to negotiate discounts on the market share of parallel imported pharmaceuticals

The market share for parallel imports when pharmacies can negotiate discounts with parallel traders and sellers of locally sourced products is analyzed both theoretically and empirically. The theoretical model shows that, with discount negotiations, pharmacies will sell locally sourced products to all consumers that prefer these or are indifferent between these and parallel imported products. The explanation is that the parallel traders have cost disadvantages because of their repacking and trading costs. Sellers of locally sourced products will therefore always underbid the marginal prices of parallel traders and this gives pharmacies an incentive to sell locally sourced products. The empirical results show that a reform allowing discount negotiations reduced the market share for parallel imports by about 11 percentage points to reach 31%. The most important mechanism is that the reform has reduced the probability that pharmacies offer consumers cheaper parallel imported substitutes.
