 Purpose of the study: To test the hypothesis of improving forecast quality through forecast pooling methods.
 Methods and objects of research: Time series of average monthly wages in the Khanty-Mansi Autonomous Okrug Yugra, Yamal-Nenets Autonomous Okrug and Sverdlovsk region are used to compare forecasting methods and methods of combining forecasts. The paper considers forecasting methods: TBATS, ARIMA, exponential smoothing, ETS, Theta, STL, polynomial regression and the approach in combining forecasts by the Granger-Ramanathan method.
 Main results of research: The paper presents the results of comparison of forecasting methods and approach in combining forecasts by Granger-Ramanathan method. Time series of average monthly wages were taken from statistical collections of Rosstat. The forecast horizon was set at 12, 18 and 24 points.
