Motivation represents a foundation corestone on which analyses in a number of the humanities and social sciences are built. For a long time, economists have seen motivation as connected with the act of giving, trying to interpret it in the context of the neoclassical economics assumptions. On the basis of representative theoretical models, Ziemek (2003) distinguishes three basic categories of motives underlying the act of giving: altruism, egoism and investment. They also form the basis of this paper. The objective of this paper is to find answers to the question what mainly motivates the Czech population in their decisions to make a donation and whether there is any interdependence among such motives. We also ask what the relationship is between the determining motives and the rate or frequency of donating. The donation models that we analyse and use as the basis of our research are nowadays considered being the principal or at least interesting donation models commonly taken into account by economists in their work. We have only focused on microeconomics models to make the text clearly targeted.
