This article proposes an approach to forecasting fertility using Google Trends search query statistics. Unlike existing studies on fertility forecasting, this paper introduces a method for aggregating thematic search queries using machine learning techniques, reducing the dimensionality of search queries through principal component analysis, and incorporating a lag structure of search queries ranging from 1 ...

Numerous studies in the field of forecasting securities prices, particularly stock prices, are aimed at finding more accurate and effective models. However, attention to multivariate forecasting, which allows for more accurate forecasts, remains underappreciated, as its implementation requires a significant increase in computing resources. Therefore, the selection of more simplified yet effective models is relevant. ...

This paper is devoted to modeling the probability of default of Russian banks in 2015–2020. There are relatively few studies on defaults of Russian banks after 2015, and our work intends to partly fill this gap. The purpose of this research is to determine the main variables which significantly impact the risk of default of ...

This study examines how the reproductive intentions of Russians changed during the socio-economic shocks that arose during the Russian-Ukrainian conflict in 2022-2023. The study used data from a representative survey of 7,967 respondents conducted in May 2023. We used multiple-choice models to identify the factors that influenced changes in fertility decisions. Most individuals who had ...

This paper presents a large anonymized dataset of homelessness alongside insights into the data-driven rehabilitation of homeless people. The dataset was gathered by a large non- profit organization working on rehabilitating the homeless for twenty years. This is the first dataset that we know of that contains rich information on thousands of homeless individuals seeking ...

A novel approach to modeling stochastic processes of goods exchange between multiple agents is presented, considering the possibility of optimizing the environment’s characteristics and individual decision-making strategies. The proposed model makes it possible to form optimal states when choosing the moments of concluding barter and monetary transactions at the individual level of each agent maximizing ...

Applying machine learning techniques to predict bankruptcy in the sample of French, Italian, Russian and
Spanish firms, the study demonstrates that the inclusion of economic policy uncertainty (EPU) indicator into
bankruptcy prediction models notably increases their accuracy. This effect is more pronounced when we use
novel Twitter-based version of EPU index instead of original news-based index. We further ...
