C91 - Design of Experiments: Laboratory, IndividualReturn

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. The paper follows on from the research (Hladká, Hyánek, 2015) that generated interesting outcomes and presented a comprehensive picture of the motives influencing donor behaviour in the Czech Republic. The authors have enriched it with a new dimension in the form of an analysis and an appropriate research method. The authors submit a theoretically reasoned set of motives influencing donor behaviour to an explorative factor analysis with the aim to determine a group of the variables that statistically "belong together", i.e. are underpinned by a common factor. The result of the analysis is reduction of the original 37 identified motives to eight new aggregate factors which are newly named and can be used for further empirical testing.

The aim of the paper was to analyze some behavioral effects, especially the effect of "hidden" tax, the "preference of progressivity" effect and some kind of "preference of short period incidence" effects of citizen. The effects predict the citizens will prefer hidden taxes to direct levies. The behavioral experiments revealed that additional information concerning the "hidden" tax and tax progressivity influences the preferences of respondents. They started to prefer the different ways of financing the public goods, those more progressive. Effect of "hidden" tax substantially diminishes after the prompting of information concerning the true tax incidence of corporate income tax. At the beginning the corporate income tax was preferred all over the groups, but later it lost its dominance and the alternative personal income tax became the favorable way how to finance of public goods. It is evident the relevant information concerning the real tax incidence and the redistributional effects of particular tax measures can significantly change the citizens view how to construct the preferred tax mix. It might also affect the process of political negotiation and reasoning.
