After the collapse of communism in Central and Eastern Europe (CEE) many countries in the region radically liberalized their foreign trade regimes in the 1990s. In particular preferential trade liberalization in the CEE countries has been promoted by the European Union in the form of the...

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...

This paper reports a field experiment investigating effectiveness of moral appeal in discouraging exam cheating. Substantial level of cheating was identified using an index of test answers similarity, contrasted with low self-reports. The treatment manipulation made an impact on self-reported...

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...

We analyze existing definitions of carbon leakage and provide a new rigorous one. This is then tested using computable general equilibrium analysis for unilateral carbon dioxide abatement programs in the EU. Our model of the global economy is disaggregated into three regions. The analysis...

A caliper mechanism is a common tool used to prevent from inexact matches. The existing literature discusses asymptotic properties of matching with caliper. In this simulation study we investigate properties in small and medium sized samples. We show that caliper causes a significant bias of the...

The main idea of this research is to check the efficiency of the Black option pricing model on the basis of HF emerging market data. However, liquidity constraints - a typical feature of an emerging derivatives market - put severe limits for conducting such a study. That is the reason why...
