Parties and candidates in the election campaign try to raise the community to vote for them by offering a variety of social policies. However, the public health expenditures have been raised among the candidates as one of the most important tools to attract votes. Thus, this study uses panel data to investigate whether the components of electoral cycle have affected the growth of public health expenditures in both developed and developing countries over the period of 1994-2010. Using the related tests, two methods of static panel (random effects) and dynamic panel estimation were selected. According to the results, the presence of electoral cycles could not be rejected in both types of countries. Based on these results, politicians in every country increase the public health expenditures before the election in hopes of gaining a greater share of people's votes.
