The assumption of the stability of preferences is a fundamental one in the theory of the consumer. Many papers within the stated preferences literature have tested this assumption, and have found mixed results. Individuals may become more sure of their preferences as they repeat a valuation task...

This paper tests whether changes in “incidental emotions” lead to changes in economic choices. Incidental emotions are experienced at the time of an economic decision but are not part of the payoff from a particular choice. As such, the standard economic model predicts that incidental...

We use a novel field experiment which jointly tests two implicit assumptions of updating models in a joint framework: that new information leads to new knowledge and that new knowledge can affect economic decisions. In the experiment, we elicit subjects’ prior knowledge state about a good’s...

In this paper we estimate the economic value of selected ecosystem services provided by White Storks in a Polish ‘stork village’. A stork village is a common name for a village with a White Stork breeding colony, often inhabited by more storks than people. Zywkowo, the best known stork...

There are two major ways in which solid waste can be sorted and recycled – at the household level, when households are required to sort waste into a given number of categories, or in specialized sorting facilities. Traditionally, it has been thought that sorting at the household level is an...

The paper reports the costs of municipal wastewater collection and treatment in Poland based on an empirical sample of 1400 operators. Treatment cost functions are investigated econometrically using the Box-Cox regression model, indicating high non-linearity and significant scale effects....

Using multiple choice tasks per respondent in discrete choice experiment studies increase the amount of available information. However, treating repeated choice data in the same way as cross-sectional data may lead to biased estimates. In particular, respondents’ learning and fatigue may lead...

For many years, stated preference researchers have been interested in the effects of information on willingness to pay for environmental goods. Within the random utility model, information about an environmental good might impact on preferences and on scale (error variance), both between and...

The paper looks at people’s preferences for the changes in selected ecosystem services resulting from new management strategies of forest areas in Poland. It applies a generalized multinomial logit (G-MNL) model to interpret the results of a discrete choice experiment (DCE) study administered...

This paper compares how increases in experience versus increases in knowledge about a public good affect willingness to pay (WTP) for its provision. This is challenging because while consumers are often certain about their previous experiences with a good, they may be uncertain about the...
