Эконометрика, экономико-математические модели
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.
A general description is given of software products designed for econometric studies. Software packages Microsoft Excel, Stadium, SPSS, and MATLAB are considered in detail.
In spite of a growing body of literature investigating the determinants of youth unemployment, studies at sub-national level are still scarce, especially for Russian regions. This article is an innovative attempt to analyse econometrically the key factors affecting the youth unemployment rate and the ratio between youth and total unemployment rates for 75 Russian regions in 2000–09. The existing literature on regional labour market performance and dynamics suggested the use of a large set of explanatory variables (with indicators of the level of economic development, the demographic situation and migration processes, and the export–import levels) in a GMM panel data analysis, taking into account both spatial correlation and endogeneity problems. Although we were searching for structural determinants, we also investigated the effect of the 2008–09 financial crisis. The econometric results, presented and discussed using several models, have key policy implications for both national and regional levels of government.
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.
