Three essays on social preferences, social dilemmas and taxation

The dissertation consists of three chapters. Chapter 1 studies other-regarding preferences of decision makers in the domain of losses. The framework of the Dictator Game is modified by introduction of a bi-directional monetary loss. Chapter 2 studies the interaction of individuals with heterogeneous characteristics in a social dilemma. The framework of the Public Goods Game is modified, by manipulating the endowment sources of the individuals included in the same group. Chapter 3 studies whether providing information on the national public expenditure to the taxpayers and whether involving taxpayers in the process of allocating tax revenues over public goods influence the level of the adequate tax rate- the fraction of income that individuals consider adequate to pay as taxes.
