Paolo Berta, Gianni De Fraja and Stefano Verzillo “Optimal Healthcare Contracts: Empirical Evidence from Italy”.
Abstract
In this paper, we investigate the contracts offered by a large healthcare purchaser to health service providers. The system, based on the DRG principle that all hospitalisations in a diagnosis group are refunded at the same rate, permits nevertheless considerable variation in the amount reimbursed within each DRG. We build a theoretical model which explains this variability as the attempt of the health authority to ensure appropriate matching between hospitals and patients. We test the model using a very large and detailed administrative dataset for the largest region in Italy. In line with our theoretical results, we show that the state funded purchaser offers providers a system of incentives such that, as required by optimality, the most efficient providers both treat more patients and also treat more difficult patients, and are compensated for doing so with a higher average payment per treatment.
Gianni De Fraja “International Mobility of Academics: Theory and Evidence”, CEPR Discussion Paper 18117, April 2023.
Abstract
The labour force in the university sector of many countries is extremely international. I propose a theoretical model to study cross border academic mobility, where academics bargain with institutions over pay and choose the countries where they live and work to maximise their lifetime utility. I then test the model on a subset of well over 900,000 research active academics over 33 years. The model predicts academics to respond to short term conditions, such as those caused by changes in their own record and exchange rate fluctuations, with the decision to move of more eminent academics being less influenced by short-term exchange rate fluctuations, but more by changes in their record. These conclusions are confirmed by the empirical analysis.
