To estimate paremeters: mean of the distribution of disutility from migration and std. dev. of the distribution of disutility from migration,
run estimation_netmig.m. It uses the empirical data from file DATA_netmig_cons.xlsx (which, itself, gathers together various data prepared in folders
data_expenditures_on_elderly, Data_migrations_eurostat, DependencyRatio_09_19 and from file Y_G_C_per_capita_09_19_RAW.xlsx).

Script estimation_netmig.m calls:
1) distance_fun.m - function that computes the distance between the model and the data (the distance is minimized to pin down the values of mean of 
the distribution of disutility from migration and std. dev. of the distribution of disutility from migration)
2) model_evaluation.m - evaluates the net immigation rates computed with the model at empirical values of private and public goods consumption
