| Abstract: | This paper analyses the factors that determineentry into the Swedish pharmaceuticals market. The analysis is based onpanel data for 22 different substances covering the years 1972 to 1996. Theresults show that profit opportunities in a particular market have apositive impact on entry. In addition, there is some evidence suggestingthat the length of the patent protection period has a negative impact onentry. |
