The flowchart starts with a text box on the top left labeled “G L P I” and a text box below it labeled “Infrastructure”. A downward arrow labeled “H 3 b, H 4 b” connects “G L P I” and “Infrastructure,” while an upward arrow labeled “H 3 a, H 4 a” connects “Infrastructure” to “G L P I”. A diagonal arrow labeled “H 2, H 4 a” extends from “G L P I” to a text box in the center labeled “Balance of Trade”. Another diagonal arrow labeled “H 1, H 4 b” extends from “Infrastructure” to “Balance of Trade”. Four text boxes labeled from left to right as “T F,” “O P,” “G D P,” and “F D I” are placed below “Balance of Trade”. Four upward arrows emerge from “T F,” “O P,” “G D P,” and “F D I,” respectively, and connect to “Balance of Trade”.Research model.
