The study measures how often customers are cheated in real-world transactions. In a preregistered field study in Prague, Czech Republic, hired confederates posed as foreigners unfamiliar with local currency. While buying snacks in grocery stores (N = 259) either in the morning or in the evening, they provided cashiers with an opportunity to steal money from them by keeping more change than they were supposed to. The customers were cheated in 21% of stores, the median overcharge was 54% of the value of an average purchase, and overcharging occurred more often in the stores with on-line reviews mentioning dishonesty of employees. Although males cheated and were cheated slightly more often than females, gender differences were not significant. In contrast with predictions of the Morning Morality Effect, dishonest behavior occurs slightly more often in the morning than in the evening. The results show that cheating of customers in grocery stores is relatively widespread and it is especially prevalent in the central city district where the odds of being cheated are more than three times higher in comparison with the rest of the city.

Purpose: This impact evaluation report describes the effects of the “Parenting Program for Disadvantaged Families” in the Czech Republic. We provide a detailed look at the quantitative data on treatment and control families in a program delivered by social workers to reduce the risk of children's misconduct. Method: The study specifies the results of two waves of quantitative research based on Parenting Young Children (PARYC), Strengths and Difficulties Questionnaire (SDQ), and items measuring parents’ attitudes toward punishment of their children. Results: The results of parental self-reported competencies and parent-reported children's behavior indicate that there was a statistically significant impact of the intervention. Discussion: There was a large effect on Supporting Positive Behavior (PARYC), and Prosocial Behavior and Peer Relationship dimensions of the SDQ. Parental practices and attitudes toward punishment are further explored, although the conclusions remain ambiguous.
