  After the financial crisis of 2008 many scholars criticised the validity of the market efficiency hypothesis of the modern financial literature. The purpose of this paper is to investigate the adequacy of market efficiency based on Hungarian, and as a reference, on American securities. Besides classical statistical tools (autocorrelation function, Ljung-Box test, Augmented Dickey-Fuller test), we also used new approaches of the literature (Variance Ratio test). In addition to the simple hypothesis tests we tried to separate the different type of time series and explain the reasons for the different behaviours.

  Company surveys and labor market prognoses point out that changes in the labor market significantly reshape the employers’ competence expectations
  towards employees. Experts predict an expansion and significant rearrangement of competence expectations. At the same time, employees may experience very different expectations during the application process. Certain employers have high expectations, while in other companies these new high expectations are not perceived. Based on the results of our qualitive research examining the competence requirements towards fresh graduates, we seek to find out how domestic companies react to change when formulating their requirements towards their employees. In the light of the forecasts, we examine which competences are the ones where employers think of new and expanding content. In our work, competences as dynamic variables are examined in the interaction between the demand side and the supply side, that is, the interaction between the employers’ competence needs necessary for their operation and their experience regarding the preparedness of the fresh graduates.
