Fee-for-service or donation? Hungarian perspectives on informal payment for health care

Although focused on Hungary, accounts from other countries facing informal payments show similar threads of discussion and dilemmas. These theories should be tested further using evidence from existing studies and new empirical research, since the validity of the gratitude payment concept is a central dilemma of effective policy making in the area. To orient future research, a possible agenda is outlined, which links evidence to be obtained to the defining features of gratitude payments.
