Keynesian p-Beauty Contest (KpBC) is one of the most commonly used laboratory experiments to study the degree of rationality of people and the learning process. It is also applicable in education as a tool to illustrate both the concept of rationality and iterative elimination of dominated strategies. The aim of this paper is to present the results of online teaching experiments in which an auto-selection mechanism has been used based on the existing social stereotypes. The repeatability of the results shows that the experiments are resistant to the distortions arising from the use of the online environment, and that a developed methodology allows to carry out reliable experimental studies.

Models of the relationship between employees and employers presented during the undergraduate and graduate studies of economics usually reflect the formal neoclassical approach. Moreover, in everyday life as well as in the public debate those relations are often presented as conflicts in which only one party may win. Such an oversimplified approach to the labor market relationships does not correspond with reality and may affect people's decisions, treating the second party as an enemy. The article presents the multistage educational experiment (18 rounds), in which students play the roles of employers and employees. Their outcomes depend on the declared involvement, their remuneration, and the level of social trust. Results of the experiment reveal that all these factors depend heavily on students' openness to communicate with other players as well as the employer-employee matching. Participation in the experiment allows students to experience that even conflict-provoking labor market relationships do not have to go along with strong disputes and radical opportunism. Learning how to cooperate in the labor market could not only be economically profitable, but it can also help to build social capital, which is even more crucial.

The article shows a possibility of applying the multi-object first-price auction to the students registration system for the class at the University Study-Oriented System (called USOS). On the basis of experimental data and the Monte Carlo simulation changes in the effectiveness were determined after the possible introduction of the new type of registration based on the auction system in relation to existing systems of registration and it was determined whether this system will motivate the students.

This paper presents a classroom experiment, the simulations, and a research which familiarize the students with the Benford’s Law. This law is widely used in a tax fraud detecting procedures. This paper shows that: i) the Benford’s Law can be useful in extending the simple perception of the probability which is presented at the lectures concerning the risk, ii) can be an excellent example of using data processing for the classroom tasks, iii) by the experience of the fraud detecting technique the students might change their attitude to cheating. The experiment and the prepared R codes can be used in the numerous courses, such as accounting, applied microeconomics, and quantitative methods.

In the models of the horizontal product differentiation it is assumed that all the consumers will decide on purchase of goods, it means that there will be the full market saturation assumption. The authors of the work study the influence of overthrowing this unreal theory on the balances in one and two dimension models of location. In order to verify the balances the experiment has been carried out to study the choices of the participants regarding the location of the company according to the level of the market saturation. The experiment confirmed the influence of the size of the company on its location and demonstrated the occurrence of negative relationship among the size of the companies and the distance between them in the balanced state. The large firms chose the central location, the Principle of Minimum Product Differentiation, when the small enterprises were creating separate monopolistic markets, the Principle of Enough Product Differentiation. Decisions that were made both by large and small enterprises as and small they were correct with the theoretical expectations. Only medium enterprises were located closer to each other than the theory was assumed. The reason of this was a desire to be located in the central point of the market in order to gain the quantity leader's position. It took place by the cost of the lost of parts of profit.
