Geng R., Kubler F.
Non-convexities and discrete choices have become important modeling tools in modern macroeconomics. Unfortunately, the existence of competitive equilibria in the presence of such non-convexities is not always ensured, and most results on the existence of equilibrium that can be found in the literature do not directly apply to models used in applications.
In this paper, we explain the three main difficulties one encounters when proving the existence and give simple sufficient conditions for the existence of competitive equilibria in stochastic OLG models with non-convex budget sets. We also give sufficient conditions for the existence of approximate equilibria that are recursive in the natural state.

This paper asks which families of volatility forecasting models create economic value in active trading, and through which integration channel that value is transmitted. Seven models drawn from four families — econometric (GJR-GARCH, HAR-J), gradient boosting (XGBoost, LightGBM), recurrent neural networks (LSTM, GRU) and a hybrid combining HAR-J with boosting — are compared on the ...

This essay explores the complex issue of determining the appropriate level of risk when implementing innovations within organizations. While innovation is widely recognized as a cornerstone of competitiveness, growth, and sustainability, excessive or poorly managed risk can lead to significant challenges. The discussion highlights key factors influencing acceptable risk levels, including alignment with corporate goals, ...

This paper examines total factor productivity (TFP) dynamics among Russian enterprises from 2018 to 2024, using translogarithmic production function estimates for 290 industries. To address endogeneity and functional dependence issues, we employ the Ackerberg—Caves—Frazer methodology with a control function approach. Our findings reveal distinct sectoral patterns. In mining, both simple average and value-added-weighted TFP rose ...

Стремительное развитие генеративного искусственного интеллекта (генИИ) усилило дискуссии о том, как новые технологии трансформируют рынок труда, особенно позиции и задачи, которые еще недавно мог выполнять только человек. Эксперименты показывают, что генеративный ИИ может обеспечить значительный прирост производительности, особенно менее квалифицированных сотрудников, что может приводить к возникновению индивидуальной зарплатной отдачи на рынке труда. Впервые для России ...

Trade sanctions generate asymmetric shocks in developing economies, reshaping their integration into global value chains (GVCs). Using a gravity framework covering 68 developing countries over the period 2000–2021, this paper examines how sanctions affect forward and backward GVC linkages. We find that sanctions significantly reduce both dimensions of GVC participation: backward linkages suffer deeper and ...

We propose double machine learning (DML) estimators for a partially linear model (PLM) with endogenous treatments and multivariate sample selection. We prove asymptotic normality of the estimators under mild regularity conditions and study finite sample properties on simulated data. The results demonstrate the importance of addressing sample selection in PLMs and the usefulness of the ...

The article analyzes the idea of a multiplicity of worlds as virtual ones. Gained its popularity in the second half of the 20th century, such an approach states that the universe can be considered as information – as a set of bits and logical operations with them (or as program code).
The hypothesis substantiates the information ...

The main thesis of the article is that the idea of A. Meinong's interpretation of the
concept of existence as an eccentric and deliberately implausible concept that implies absurd
consequences is unjustified. The author shows that, being correctly presented, this
approach not only does not contradict our typical and natural intuitions, but corresponds to
them more than any other ...

The main point of the article is that the Russellian analysis of the concept of existence does
not provide a significant economy of ontology in comparison with the Meinongian one. The reason
lies in the unavoidable need to preserve the possibility of numerical distinguishing between various
nonexistent (unrealized) objects. For example, Sherlock Holmes is definitely not the same ...

Contemporary philosophical anthropology fluctuates
between, on the one hand, the positivist rejection of
the metaphysically loaded concepts of “essence” and
“existence” in their theoretical constructions and, on
the other, the essentialist traditions in which these concepts have played and continue to play a decisive role.
Positivism rejects the ethical component of philosophical anthropology, reducing it to relativism. Essentialism
nourishes the metaphysical ...

A competent acquaintance with Martin Heidegger’s major works, such as “Being and Time”, is impossible without understanding the primeval methodological foundations of this German thinker, – or, in other words, without comprehending the principal connection between his existential analysis and the destruction of the European metaphysical knowledge. The inevitable connection of ontic and ontological levels ...

The subject of this article is Heidegger's existentially-ontological consideration of human being (Dasein) as the transcending structure. This article proves the conclusion that the interpretation of Heidegger's intentional consciousness as "transcendence"
means going beyond Husserl's phenomenology. Consequently, raising an issue of intentionality as a specific kind of Being (rather than cognition) Heidegger in contrast with Husserl ...

Based on the Fréchet mean, we define a notion of barycenter corresponding to a usual notion of statistical mean. We prove the existence of Wasserstein barycenters of random probabilities defined on a geodesic space (E, d). We also prove the consistency of this barycenter in a general setting, that includes taking barycenters of empirical versions of ...
