my subject is ( impact of financial development on economic growth)

my variable 1 is economic growth as GDP will represent it.

for financial development, I have to put ratio of m3,

-Claims on private sector (annual growth as % of broad money)

-Claims on central government (annual growth as % of broad money)

-Claims on other sectors of the domestic economy (annual growth as % of broad money)

Do I sum those up for M3 ratio for variable 2?
