Following beliefs or excluding the worst? The role of unfindable state in learning
European Economic Review. 2024. Vol. 162. Article 104653.
An agent learns in continuous time from two information sources, each associated with a hypothesis. If a hypothesis is true, the associated source confirms it at a positive rate. False hypotheses are never confirmed. Among the two hypotheses, either exactly one is true or both are false. The agent’s optimal learning strategy has two phases. During the first phase, the agent follows his beliefs; that is, at each moment, he learns from the source associated with the most likely hypothesis according to his current beliefs. During the second phase, he focuses on excluding the least likely but more important hypothesis.

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 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 ...

We study the effect of a merger on R&D activity in a dynamic model with uncertainty about the feasibility of innovation. The merger has three effects: it may reduce the number of follow-up innovations (cannibalization effect), increase the probability of the first game-changer innovation (appropriability effect), and bring this innovation forward in time (informational effect). ...
