Abstract

This research aims to analyze the impacts of interest rates and urea fertilizer price policies on the welfare of
cassava economic stakeholders in Lampung Province. This study uses the secondary data 1990-2010
analyzed by using two stages least squares (2SLS) model, and simulated based on changes in policies. The
welfare of cassava economic stakeholders is based on the net surplus between producer surplus and
consumer surplus. The simulation showed that the 10 % increase in interest rate caused the decrease in net
surplus of 36.25 percent. The 10 % decrease in interest rate increased the net surplus by 10.18 percent. The
15 % rise in urea fertilizer price caused the decrease in net surplus by 7.69 percent. Moreover, the
combination of 15 % increase in urea fertilizer price and 10 % decrease in interest rate caused the increase
in net surplus by 325.17 percent.
