This manual is written as an auxiliary educational material for the course "Methods of microeconomic analysis", which is studied by students of the 4th year of the Faculty of Economics of Novosibirsk State University . This course focuses primarily on the study of sections of microeconomic theory, collectively referred to as the 'market fiasco'. Since it completes the preparation of students of the first stage, it takes into account the peculiarities of teaching theoretical disciplines at the Faculty of Economics of NSU .. Thus, if necessary, traditional sections of microeconomics are also discussed, which have not found their proper place in previous courses (in particular, decision-making under conditions of uncertainty), the possession of which is necessary for mastering the main material of the course.
