US is the largest destination country for Indonesian rubber export. This research used an autoregressive distributed lag regression (ARDL) model on 29-years annually data for the period 1989-2017 to find the empirical evidence of some economics determinants towards Indonesian rubber export to US. This research used US-IDR exchange rate, US GDP, Indonesian rubber price for US, and US population as the proxy of economic liberalization.
