The returns to scientific collaboration have been widely acknowledged. The general trend observed in top scientific journals is an increase in collaborative activities both between researchers and between institutions, especially with regard to international co-authorship. Not only there is a...

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...

Despite decades of anti-discriminatory legislation, wage discrimination against women is believed to be a major source of social inequality in the developed economies. In the present study we investigate the issue of gender wage gap in Poland. The analysis is carried out both with regard to the...

In this paper we propose Generalized Momentum Asset Allocation Model (GMAA). GMAA is a new approach to construct optimal portfolio and is based on close examination of asset’s returns distribution. GMAA tries to capture certain market phenomena and use information they contain as predictors...

In this project we sought to contribute to extant literature on overconfidence by identifying it in a large, heterogeneous sample making familiar, repeated choices in a natural environment which provides direct feedback. In Study 1 we elicited predictions of own finishing time among participants...

This paper is a follow-up to Marrero and Rodríguez (2012), who estimated the inequality of opportunity (IO) in Europe in 2005. We use the EU-SILC 2005 and 2011 databases to compare the IO in 23 European countries before and after the Great Recession. The parametric procedure of Ferreira and...

Authors present the occupational structure of Polish lands at the turn of 20th century on the basis of censuses carried out in Germany (1895), Russia (1897) and Austria (1900). Our research provides corrections to the errors of the censuses, to a considerable extent. As a result, we present an...

As of 2007 increased labor force participation of the elderly has been observed in Poland. In 2009 a reform in the eligibility criteria narrowed the scope of early retirement opportunities for majority of the occupations. While labor force participation in the directly affected cohorts continued...

From a theoretical perspective the link between the speed and scope of rapid labor reallocation and productivity growth or inequalities remains unclear. Do reallocations with more flows tend to produce higher productivity growth? Does such link appear at the expense of higher inequalities? We...

The contingent valuation (CV) method uses respondents’ stated choices made in hypothetical situations to infer their preferences for environmental public goods. It enables the general public’s preferences to be stated in monetary terms and hence to estimate the economic value of a change in...
