Personality is a key factor in purchasing acceptance in new technological environments. Previous research shows that personality traits are predictors of motivation for online shopping. According to the theory, there are five personality traits: extraversion, conscientiousness, openness to new experience, agreeableness, and neuroticism (Lissitsa and Kol, 2021.) that may have different effects on shopping in different settings and among different cohorts. Generation Y refers to all people born in the period from 1980 to 1995, while Generation Z refers to people born between 1996 and 2010. It has been shown that the behavior of these two generations differs during mobile shopping (Lissitsa and Kol, 2021.), but it is unknown whether there are differences in the purchasing hedonic products of these two generations. Mobile shopping as a specific type of online shopping gradually developed from e-commerce. It represents consumer activity aimed at purchasing products and services via mobile devices, such as smartphones and tablets. It is important for businesses because almost two-thirds of Internet users purchase various products and services via mobile devices, with further growth predicted. The subject of the paper is to investigate the role of personality traits in the mobile purchase of hedonic products. The aim of the thesis is to investigate the role of five personality traits in the mobile purchase of selected hedonic products among two (different) generations of consumers Y and Z. Therefore, a primary descriptive, i.e., quantitative research was conducted on a purposeful convenience sample of 239 respondents to investigate the role of personality traits in the mobile purchase of hedonistic products of generations Y and Z. The research revealed a positive influence of extraversion, agreeableness, openness to experience and conscientiousness on the intention to mobile purchase of hedonic products among generation Z. In generation Y, no correlation was found between personality traits and the intention to mobile purchase of hedonistic products. The limitations of the research are related to the convenience purposive sample of respondents from one country.
