Elena Vladimirovna Kossova is an Associate Professor at the Department of Applied Economics within the Faculty of Economic Sciences at the National Research University Higher School of Economics (HSE). She has been with HSE since 1995, accumulating 30 years of scientific and teaching experience. Her academic background includes a Candidate of Physical and Mathematical Sciences degree from Lomonosov Moscow State University. Educational Background: 1995: Candidate of Physical and Mathematical Sciences, Lomonosov Moscow State University, specialty 01.01.05 "Probability Theory and Mathematical Statistics" 1995: Postgraduate study, Lomonosov Moscow State University, Faculty of Computational Mathematics and Cybernetics 1990: Specialty in Applied Mathematics, Lomonosov Moscow State University, Faculty of Computational Mathematics and Cybernetics, qualification "Mathematician" Elena Kossova's research focuses on Microeconometrics, Probability Theory, Mathematical Statistics, and Applied Econometrics. Her work particularly emphasizes microeconometrics of qualitative data, models with qualitative and limited dependent variables, and the application of advanced statistical methods to economic problems. She has developed expertise in handling complex data structures including non-random selection and endogeneity issues. Her teaching portfolio includes Probability Theory and Mathematical Statistics courses alongside specialized microeconometrics courses for both undergraduate and graduate students. Her publication record shows a consistent focus on applying econometric methods to analyze health economics, consumer behavior, and social policy issues in the Russian context. A significant portion of her recent work examines the relationship between alcohol consumption, health outcomes, and socioeconomic factors, as well as the impact of education on health. Her methodological contributions include developing and comparing various approaches to handling sample selection bias and endogeneity in microeconometric models. Scientific Awards and Recognitions: Diploma "Founder of the Higher School of Economics" (November 2022) Honorary title "Honorary Worker of Education of the Russian Federation" (November 2022) Medal "Recognition - 25 years of successful work" (August 2021) Honorary Badge of the 2nd Degree of the Higher School of Economics (December 2018) Medal "Recognition - 20 years of successful work" (January 2018) Certificate of Honor of the Ministry of Education and Science of the Russian Federation (November 2012) Multiple Academic Work Allowances (2012-2018) Publication Bonuses for international journal articles (2018-2022) Best Teacher awards (2012-2025) Professor Kossova serves as a scientific supervisor for the educational program specialization in "Economy and economic policy." She has supervised doctoral research, including Potanin B.S.'s 2020 dissertation on extending regression models with endogenous switching and non-random selection. She is actively involved in research projects, including as project leader for the Russian Science Foundation grant No. 21-18-00427 on "Development and application of econometric estimation methods for economic models considering endogeneity and non-random observation selection." Her work demonstrates strong collaboration with colleagues both within HSE and internationally. Professor Kossova maintains active participation in academic conferences, particularly the annual "Applied Econometrics" conference series at HSE and international econometrics events. Her consultation hours are held via Telegram chat for students taking her courses in TViS (Probability Theory and Mathematical Statistics) and Microeconometrics.
