The impacts of health sector reform on the efficiency and productivity of public and private hospitals in Turkey
(2009) Diler, Müge
Hospitals consume the largest share of government health resources. Since they account for such a large share of health expenditure, improvements in their efficiency and productivity will yield tremendous benefits for the entire health sector. On this basis, in 2003, the government of Turkey declared a reform program called “Transformation in Health”. This study by using a rich panel data of 440 hospitals operating in 81 province in Turkey (observed throughout 2001-2007 i.e. pre and post reform periods) addresses the impacts of health sector reform on the efficiency and productivity of the public and private hospitals by employing Data Envelopment Analysis (DEA), bootstrapping and Malmquist productivity index. The results of the analysis indicate that slightly reduced efficiency of previously SSK owned hospitals have been more than offset by increased efficiency in MoH hospitals as well as in private and university hospitals, leading to an accessible, standardized and higher quality health services covering almost the whole population and that in overall, the reform has improved the productivity of all hospitals implying that health sector reform has succeeded.

On the measurement of productivity and environmental efficiency in the presence of the joint production of goods and bads : an application to OECD countries
(2003) Yörük, Barış K.
Productivity measures, which do not account for environmental performance, are biased. When it comes to incorporating the developments in environmental performance into the measurement of productivity, the traditional “Tornquist type” indices fail to measure the productivity particularly in the cases where price information on undesirable outputs do not exist. Therefore, there is a need for an alternative measure which puts due emphasis on production with negative externalities without requiring price information. Motivated by these facts, this study first employs a Malmquist index for OECD countries without considering the existence of pollutant data and then to overcome the shortfall of this index, a Malmquist-Luenberger productivity index is employed. Furthermore, using an index number approach, environmental performance of OECD countries is also evaluated, by using a method, which relies on the computation of the distance functions within a DEA framework.
