Abstract

Our study examines the long-term relationship among per capita gross domestic product (GDP), per capita health expenditures and population growth rate in Turkey during the period 1984–2006, employing the Johansen multivariate cointegration technique. Related previous studies on OECD countries have mostly excluded Turkey—itself an OECD country. The only study on Turkey examines the period 1984–1998. However, after 1998, major events and policy changes that had a substantial impact on income and health expenditures took place in Turkey, including a series of reforms to restructure the health and social security system. In contrast to earlier findings in the literature, we find that the income elasticity of total health expenditures is less than one, which indicates that health care is a necessity in Turkey during the period of analysis. According to our results, a 10% increase in per capita GDP is associated with an 8.7% increase in total per capita health expenditures, controlling for population growth. We find that the income elasticity of public health expenditures is less than one. But, in the case of private health care expenditures, the elasticity is greater than one, meaning that private health care is a luxury good in Turkey.

Notes

  1. Please see Appendix for a chronology of reforms.

  2. SSK health facilities were transferred to the MoH; SSK members gained access to all MoH hospitals. The range of services provided for Green Card holders, which included only inpatient healthcare services prior to HTP, has been expanded over time to include outpatient health expenses.

  3. The extra charges of private health facilities are paid by the patient as an out of pocket payment.

  4. UHI aims to cover the whole population. However, the reform process will take time; GERF members and green card holders are planned to be covered by UHI in 3 years. In this study we cannot examine the effect of the introduction of the UHI since we have data only up to 2006.

  5. Both OECD Health Data 2007 and 2008 provide the same health expenditures series up to year 2005. However, regarding the GDP data, the 2008 version has the new GDP series recently adjusted by the Turkish Statistics Institute, whereas the 2007 version has the old series. The new GDP series has been adjusted starting from 1998. Therefore the 1984–2006 series has a break in year 1998. To avoid this problem, we have chosen to use the old GDP series in the 2007 version of the OECD Health Data.

  6. Since these tests are very commonly used in the literature, we do not provide detailed information on them. Please see Dickey and Fuller [6] and Phillips and Perron [25] for details.

  7. E-views employs the MacKinnon critical values in the ADF and PP tests.

  8. Even though the ADF and PP tests are asymptotically equivalent, they may differ in finite samples because of the different ways in which they correct for the serial correlation of the test regression. Please see Perron and Ng [24] and Schwert [27] for a detailed comparison of these techniques.

  9. According to this system, 5 (or at most 10) European Union countries’ drug prices were followed and the cheapest were taken as a reference for drug prices in Turkey.
