HSE Economists Reveal How the Wage Gap Emerges Among Vocational School Graduates
HSE researchers examined the careers of 600,000 graduates of Russian secondary vocational education programmes and found that at the start of their careers, the gender wage gap reaches 23%, doubling after three years. This disparity is largely due to male and female students choosing different occupations when enrolling in vocational schools. These were the findings made by Sergey Roshchin, Natalya Yemelina, and Ksenia Rozhkova from of the HSE Faculty of Economic Sciences. The article has been published in Educational Studies.

HSE Researchers Make Aldehydes Perform Dual Function
Chemists from HSE University have discovered a way to carry out a reductive addition reaction without using an external reducing agent. Instead, the required 'resource' is supplied by the aldehyde itself, one of the reaction participants. This approach helps prevent unwanted side reactions, reduces toxicity, and simplifies the production and synthesis of organic molecules, including those used in the manufacture of medicines. The study has been published in Journal of Catalysis.

HSE Scientists Explain Why Findings in Autism Research Differ
Researchers from the Cognitive Health and Intelligence Centre at HSE University conducted the first-ever systematic review of studies on the specifics of emotion-from-motion perception in autism. The review showed that differences found between autistic and non-autistic individuals are largely associated with the experimental design and the types of tasks given to study participants. The review findings have been published in Research in Autism.

Instability of Equilibrium Price

2018.
Levando D. V., Sakharov M.
We develop a theory of market instability caused by strategic trade with complete information and without outside shocks. We focus on general equilibrium duopoly as a strategic market game with infinite strategies, and a pricing mechanism. First order conditions of the game are the 1-st kind integral equations of Fredholm, which have many solutions.  A solution is a probability distribution and can be approximated only. We suggest a modification of Tikhonov regularization for their numerical approximation. Impossibility to construct a unique and exact solution imposes a restriction on existence of converging common beliefs of players about actions of each other, on existence of rational expectations, and on price discovery property of the market, although the market is informationally efficient. Approximated price has unremovable instabilities, `natural instabilities', specific to parameters of a chosen approximation. Our result is also related to existence of sun-spot equilibrium, and noise trade.

On algebraic and topological semantics of the modal logic of common knowledge S4CI
Shamkanov D. S., Logic Journal of the IGPL 2024 Vol. 32 No. 1 P. 164–179
For the modal logic S4CI, we identify the class of completable S4IC-algebras and prove for them a Stone-type representation theorem. As a consequence, we obtain strong algebraic and topological completeness of the logic S4CI in the case of local semantic consequence relations. In addition, we consider an extension of the logic S4CI with certain infinitary derivations and establish ...

Tautologies, inferential processes and constraints on evoked knowledge
Vilinbakhova E., Escandell-Vidal V., Zevakhina N., Journal of Pragmatics 2022 Vol. 191 P. 55–66
In the literature on nominal tautologies, it is assumed that common knowledge is a crucial ingredient for their interpretation. This paper explores a different approach: we argue that invoking shared knowledge is at the same time too strict and too vague as a condition for the understanding of tautologies in context. More specifically, we claim ...

The dynamics of different maturity loans interest rates is studied. dentification strategy, that explicitly allows to introduce the impact of future interest rates expectations and to estimate their significance is used. It is shown that for Russian banking sector in 2010-2020 expectations about future interest rates path have significant but modest impact on current loan ...

Joint attention and perceptual experience
Geurts L. B., Battich L., Synthese 2020
Joint attention customarily refers to the coordinated focus of attention between two or more individuals on a common object or event, where it is mutually “open” to all attenders that they are so engaged. We identify two broad approaches to analyse joint attention, one in terms of cognitive notions like common knowledge and common awareness, ...

Fiat Money Oligopolistic Economy With Labor/Leisure Trade-Off and Equilibrium Default
Levando D. V., Sakharov M., / Series SSRN Working Paper Series "SSRN Working Paper Series". 2019.
We are constructing an imperfect competition general equilibrium model, with non-consumable money and labor market; our toolkit is an equilibrium default model of Shubik-Wilson (1978). Our result has an ‘equilibrium volatility’ simultaneously occurring at all three markets: labor, goods, and credit market, with a fixed money supply from a bank. A worker and an entrepreneur strategically ...

Equilibrium Market Volatility in Imperfect Competition of General Equilibrium
Levando D. V., Sakharov M., / Series SSRN Working Paper Series "SSRN Working Paper Series". 2019.
We develop a theory of equilibrium market volatility in a general equilibrium duopoly with complete information. The resulting economic system possesses a property, which can be described as ‘natural volatility’ of markets, even if players have complete information. Economy is described as a strategic market game where every player has market power as a buyer and ...

Natural Instability of Equilibrium Prices
Levando D. V., Sakharov M., / Series Research Paper Series No. 01/WP/. 2018.
We develop a theory of market fluctuations caused by strategic trade with complete information and without outside shocks. The constructed general equilibrium duopoly is a strategic market game with infinite strategies and multiple mixed strategies equilibria. First order conditions (FOC) of the game are the ill-posed problems (Hadamard, 1909), but every equilibrium mixed strategy can ...

Grade expectations: Rationality and overconfidence
Magnus J. R., Peresetsky A., Frontiers in Psychology 2018 Vol. 8 P. 1–10
Confidence and overconfidence are essential aspects of human nature, but measuring (over)confidence is not easy. Our approach is to consider students' forecasts of their exam grades. Part of a student's grade expectation is based on the student's previous academic achievements; what remains can be interpreted as (over)confidence. Our results are based on a sample of ...
