The poorest nations of the world suffer from extreme disease burdens, which go largely untreated because weak incomes and the prevailing system of intellectual property rights fail to provide sufficient incentives to develop new treatments and distribute them at low cost. Recent price reductions...

We generalize an earlier model of international vertical pricing to explain key features of parallel imports, or unauthorized trade in legitimate goods. When a manufacturer (or trademark owner) sells its product through an independent agent in one country, the agent may find it profitable to...

We investigate the welfare impact of parallel imports using a large panel data set containing monthly information on sales, ex-factory prices, and further product characteristics for all 700 anti-diabetic drugs sold in Germany between 2004 and 2010. We estimate a two-stage nested logit model of...
