Forecasting internal migration in Russia using Google Trends : Evidence from Moscow and Saint Petersburg

This paper examines the suitability of Google Trends data for the modelling and forecasting of interregional migration in Russia. Monthly migration data, search volume data, and macro variables are used with a set of univariate and multivariate models to study the migration data of the two Russian cities with the largest migration inflows: Moscow and Saint Petersburg. The empirical analysis does not provide evidence that the more people search online, the more likely they relocate to other regions. However, the inclusion of Google Trends data in a model improves the forecasting of the migration flows because the forecasting errors are lower for models with internet search data than for models without them. These results also hold after a set of robustness checks that consider multivariate models able to deal with po-tential parameter instability and with a large number of regressors
