The paper describes the main approaches to forecasting macroeconomic indicators using large data sets, as well as an overview of the empirical work in this area.

The paper provides an empirical analysis of the predictive properties of the various models of Russian macroeconomic series: different time series models and factor models (forecasts constructed using large data sets).

We use to consider Russia as a commodity state whose welfare was mainly based on extraction and export of hydrocarbons. Well, Russia has one of the biggest oil and natural gas endowments, virtually dominates at the European crude oil and natural gas markets and actively builds up export of oil...
