Abstract:
In this thesis we test the hypothesis of efficiency induction through buyer power. To do so, we analyse the case of public hospital contracting in Catalonia. First, we build a principal-agent model with hidden action, which describes the relationship between the public buyer and a hospital provider. Second, we build a measure of buyer power based upon a sample of 55 hospitals from the public network. This is an index that measures the relative buyer power exercised by the public buyer agency over each hospital. Finally, efficiency scores have been obtained using a Data Envelopment Analysis (DEA) approach. In order to test the hypothesis we use a Tobit regression model. Estimation results provide some evidence concerning a positive effect of buyer power on hospital provision efficiency.
