Background. The effectiveness of digital game-based learning is an important issue. Mobile learning games (MLG) are rapidly growing trends among the digital game-based learning genre. Although many studies have been conducted and mobile games have been shown to have an unquestionable potential as a learning method, their effectiveness has not been fully proven, and the positive impacts and outcomes of mobile learning games with respect to learning have yet to be investigated. Aim. The study aimed at capturing the cognitive learning outcomes and the process of knowledge acquisition. The study has demonstrated both positive and negative cognitive learning effects of using mobile learning game in comparison with the textbook learning process. Methodology. This article presents a comparative study conducted on a group of 160 freshman students majoring in management and finance. The participants of the study, divided into subgroups, were taught using either textbook-based learning or a mobile learning game. Three tests were applied to measure their performance: a pre-test at the beginning of the experiment, and two post-tests, the first administered directly after the learning process and the second 2-3 weeks after the initial learning. Results and recommendations. MLG have been proven to create many positive effect for learning. It is as effective in transferring factual knowledge as textbook learning, when measured directly after the learning process. In longer term, the effects are blurred because the affective effects interfere with the measurement.

The main aim of this article is to assess the influence of change in Prime Minister on Polish stock market. Prime Minister Szydło resigned shortly after she survived the second vote of no confidence on December 8, 2017, and was replaced by Morawiecki, the Vice-Prime Minister and Minister of Finance, and a former CEO of a large bank. 1 Considering the aforementioned context, this study tests four hypotheses regarding the market reaction in terms of companies' shareholder structure. An event study analysis was performed to calculate cumulative abnormal returns, and regression models were estimated to test the hypotheses. The author finds significant negative price changes only for stateowned enterprises (SOEs) both directly and indirectly controlled by the government. I assume that this reaction in the case of SOEs was caused by the uncertainty related to the likely changes in the management.
