Experimental Investigation of Discrimination of Mothers in the Labor Market
Kočová, Alžběta ; Pertold-Gebicka, Barbara (advisor) ; Víšek, Jan Ámos (referee)
The aim of this thesis is to determine the degree of discrimination of mothers in the Czech labor market during employee selection. We conduct an Internet field experiment which allows us to study the effect of the different lengths of parental leave on the probability of being invited for a job interview. We test three years long parental leave, a typical length in the Czech environment, against two years long parental leave as the shortest usual length, using a mother long after parental leave as our third control group. We found a slight preference for the three years parental leave, but we cannot confirm the hypothesis of three years leave being significantly preferred to two years leave at conventional confidence levels. The most significant is the result where resume of high-quality was sent. The results about the role of social norms from a survey among hiring specialists indicate that from two opposing effects - losing knowledge and working experience the longer a mother is on parental leave, versus losing flexibility at work the younger her child is - none is of higher concern if comparing three years leave and two years leave.

Does the probability to herd decrease when decisions are of higher importance? Experimental Approach
Kočová, Alžběta ; Cingl, Lubomír (advisor) ; Maršál, Aleš (referee)
In this thesis I study the effect of decision importance on propensity to engage in herding behaviour and what is bounded rational, optimal, utility maximizing strategy for agents. In the beginning, prior literature on herding behaviour and decision importance is reviewed. The only research connecting these two issues was done in psychology. Therefore a comparison and critique of psychological research versus experimental economics is provided in the methodological part. The main part of this thesis is designing an experiment aimed at differentiation of the propensity to engage in herding behaviour with respect to the importance of the decisions being made. People decide in a cascade among two option according to signals obtained. Eight different treatments are run, each with different size of monetary reward as a motivation. Everyone gets two signals, one private and one public. In situations when these signals are contradictory and of the same informativeness, decisions are measured and compared among treatments. Main hypothesis is that people are less likely to be influenced by other people's decisions as the task importance rises. Also data analysis is outlined.
