Research & Expertise – News

Researchers from HSE University have developed a mathematical model that explains the levitation of charged dust particles over the sunlit lunar surface for almost any latitude. For the first time, the model takes into account the Earth’s magnetotail—a particular area around our planet. The research data is important for planning the Luna-25 and Luna-27 space missions. The study was published in Physics of Plasmas.

Why do people sometimes overestimate their knowledge—more often than not, those who are not well-versed in the subject at hand? Twenty years ago, two researchers studied this phenomenon and tried to explain it from a psychological point of view. This phenomenon is now known as the Dunning-Kruger effect after the names of the researchers. According to a report presented at a seminar of the HSE Department of Applied Economics, this effect has a purely statistical explanation.

On Wednesday, December 9, the National Research University Higher School of Economics hosted an Institute of Control Sciences seminar "Expert opinion and data analysis".

Mathematicians of the Higher School of Economics have calculated the effectiveness of measures taken to fight the coronavirus epidemic in different countries. They have concluded that the scale of anti-epidemic measures does not necessarily directly affect the disease rate, suggesting that one of the main reasons for this is the willingness of citizens to clearly, honestly and consistently comply with anti-epidemic measures.

On Wednesday, September 16, the National Research University Higher School of Economics hosted a regular meeting of the All-Moscow seminar "Mathematical methods for analysing optimal solutions in economics, business and politics".

During the seminar, there were discussed several ongoing research projects: 
1) Pavel Serebrennikov - "Interval Methods of DEA and Their Application for Evaluating the Performance of Universities"
2) Anna Rezyapova - "Governance of International Migration"
3) Alina Roman - "Network Analysis of International Trade: 2001-2016"

On Wednesday, May 20 the honorary lecture of the XXI April International Academic Conference on Economic and Social Development and the all-Russian seminar "Mathematical methods of decision analysis in economics, finance and politics" was held. Y. Shi gave a lecture on "Big Data Analysis: Theory and Applications"

On Sunday, May 17 the scientific seminar of the International Centre of Decision Choice and Analysis was held. M. Ermolova discussed the paper on "Sustainable Shadow Banking" of Guillermo Ordonez.

On Sunday, May 10 the scientific seminar of the International Centre of Decision Choice and Analysis was held. L. Kadyrova on gave a lecture on "Analysis of the impact of the coronavirus pandemic on modern society"

On Sunday, May 3 the scientific seminar of the International Centre of Decision Choice and Analysis was held. A. Ivanov gave a lecture on "Manipulability indices and their calculation for collective decision rules".
