Эконометрика в задачах и упражнениях
The evolution of two subject areas in the field of mathematical economics is investigated and described - i.e. econometrics as a science and economic-mathematical methods as a scientific discipline, from the stage of their origin to the present time.
The paper summarizes main recent sociological, epistemological, methodological and ideological trends in modern economics and tries to evaluate its current state and further perspectives. Special attention has been paid to a change in economists’ methodological ideal: economic science began with trying to become like physics but actually has become like medical statistics. The paper’s general conclusion is that what we are witnessing today in modern economics is simply an ordinary working state rather than a triumph or a crisis. However, that state is not very promising since the period of new large theoretical ideas seems to be over for economics, the new atheoretical tendency in it is becoming stronger and in the very near future, economics is most likely to become more and more interventionist.
The article describes a method that allows to improve the content of disciplines of the mathematical cycle by dividing them into invariant (general) and variable parts. The invariants were identified for such disciplines as «Linear algebra», «Mathematical analysis», «Probability theory and mathematical statistics» delivered to Bachelors program students of economics at several universities. Based on the selected invariants, topics for the organization of problem-based learning and research activities of students focused on the content of the course «Econometrics» are proposed.
This paper presents a preliminary analysis of hotel room prices in several European cities based on the data from Booking.com website. The main question raised in the study is whether early booking is advantageous indeed, and if so, how early should it be? First a script was developed to download more than 600 thousand hotel offers for reservations from 25 March 2013 to 17 March 2014. Then an attempt to discover more details concerning the early booking effect was made via basic statistics, graphical data representation and hedonic pricing analysis. It was revealed that making reservations in advance can be really gainful, although more data and research are needed to measure the exact numbers, as they depend on at least seasonality and city.
