Research on national health expenditures points out the importance of factors related to demand and supply of medical services and the level of aggregate income, ignoring the role of politics in health policy. The primary objective of research presented in this dissertation is to analyze the relationship between health care expenditures and political parties and whether the relationship varies over time and by country. In addition, the effects of institutional structures of health, constitutional veto points, and globalization are assessed.Research methods include trend analysis of expenditures based on political traditions and time series cross-sectional study design using annual national level data between 1970 and 2000 from 21 developed countries. The main explanatory variables are the cabinet composition measured as cabinet share of social democratic, Christian democratic, center and liberal parties, cumulative years in government, constitutional veto points, financial structure of health system, the strength of primary health care, globalization and membership in Euro-zone. The models controlled for population aging, GDP per capita, share of inpatient care expenditures in total health spending, government deficit and female labor participation rates.Trend analysis suggested that public expenditure levels in Christian democratic countries were as high as in social democracies; however, they had higher levels of private expenditures, both from private insurance and out-of-pocket payments. Ex-Authoritarian countries had the highest growth rates in public expenditures on health, bringing these countries to the levels of liberal countries in 2000. Panel data analysis indicated a positive relationship of social democratic parties with public spending on health. Christian democratic parties had higher public expenditure levels only when they were in majority governments. The relationship between political parties and health expenditures varied over time and by country. Globalization exhibited negative relationship with total health expenditures and public spending on health. Members of the Euro-zone had lower public expenditures on health compared to non-members. As expected, GDP per capita had a strong influence on total and public spending on health and their growth rates, while population aging was found to be positively associated only with private expenditure growth.
