People often face choices where outcomes are both delayed and uncertain. Numerous studies of delayed gains and losses show the hyperbolalike discounting process of delayed payoffs. We assumed that when evaluating a delayed lottery people act according to the prospect theory model, where payoffs are discounted according to a hyperbolic function. The problem that we addressed is whether the α parameter of the value function v( ) and the γ parameter of the probability weighting function w( ) differ for evaluations of delayed and instant lotteries. We found that when people compare delayed certain payoffs with delayed risky payoffs they are more risk prone than in situations where both certain payoffs and risky payoffs are instant. However, when people compare present certain payoffs with delayed risky payoffs they are less risk prone than in situations where both certain payoffs and risky payoffs are instant. Additionally, the probability weighting curves were more linear for delayed lotteries than for instant lotteries (people were more sensitive to changes of probability).

The present research investigated the perception of the flood threat and willingness of inhabitants of regions experiencing regular severe floods to take preventive actions. Residents of two type of regions were compared: those living in a region protected by flood levees vs. residents living unprotected regions. Inhabitants of the area protected by the levees resulting in the rare experience of flood, perceived probability of flood as lower and reported higher willingness to take preventive actions than inhabitants of the area unprotected by levees. Similarly as in many previous studies personal experience and social norms turned out to be crucial factors in determining self-protective behavior. On the other hand unlike in other studies, we found no relationship between decision makers’ willingness to take preventive actions and factors related to threat appraisal, such as the perceived magnitude of loss and the perceived probability of damage. Finally, we found that the impact of a given factor on willingness to protect oneself against a hazard may depend on the kind of measure of the protective behavior

Traditional studies on political consequences of electoral systems were recognising electoral formula as the most important variable responsible for the consequences generated by a given electoral system. Meanwhile, recent studies suggest that the impact of this variable is defi nitely overrated. The article shows how the number of seats won in electoral districts affects the political parties and their candidates' chances of winning both in the proportional representation voting systems as well as in the majority and plurality ones. Using the examples of Polish parliamentary elections, the present paper both examines the thesis according to which larger electoral districts always increase proportionality and identifi es the conditions under which the thesis fi nds its application.

Studies show that people perceive income inequality differently than most popular income inequality measures and axioms (postulated properties of inequality) indicate. This article synthesizes and reviews different results on income inequality perception. It presents basic income inequality axioms and analyses the level of support found in multiple studies. The paper shows that while answers to particular questions seldom perfectly agree with income inequality measures, the general pattern of respondents' answers is strongly correlated with these measures. It also argues that the observed differences can be partially explained by following Amartya Sen’s suggestion that income inequality is a multidimensional concept (1973, p. 48).

The presented research shows that consumer choice of product depends on the sequence in which products are presented. When they were presented according to decreasing prices the customer chose more expensive products than in the case of increasing prices. However this happens only in case of paying cash not voucher. In order to rule out the alternative reasons of this effect another study was conducted. Participants of the second study were randomly acquainted with 10 product brands. Then they chose one of ten products which were sorted according to their prices: decreasing or increasing. Again, when paying cash, participants chose more expensive products when they were sorted according to decreasing prices. The results of second research suggest that the presented differences in choosing products cannot be explained by anchoring heuristic, the effect of priority, or incomplete information processing.
