contrichution

Contribution to the growth rate of an agregate in chained prices

CALLING SEQUENCE

cont=contrichution(xvol_lower,xvol_upper,xval_lower,xval_upper)

PARAMETERS

Input

* xvol_lower = a ts, the series in volume whose contribution is to be calualted

* xvol_upper = a ts, the aggregate in volume

* xval_lower = a ts, the values of the series whose contribution is to be calualted

* xval_upper = a ts, the values of the aggregate

Output

* cont = a ts, the contribution

EXAMPLE

// load the quarterly data on French consumption published in Februray 2022 by Insee
global GROCERDIR ;
load(GROCERDIR+'\data\fra_cons.dat')
// calculates the contribution of energy consumption to consumption of industrial products
cont_P3M_DE=contrichution(P3M_DE_7CH,P3M_DI_7CH,P3M_DE_3,P3M_DI_3)
// calculates the contribution of manufacturing consumption to consumption of industrial products
cont_P3M_DIM=contrichution(P3M_DIM_7CH,P3M_DI_7CH,P3M_DIM_3,P3M_DI_3)
// shows the growth rate of consumption of industrial products, the contribution of energy consumption
// and the contribution of manufacturing consumption (all in %)
