This paper aims to explore the determinants of household income and
expenditure growth, and assess whether the poor are benefiting from economic
development. Using regression analysis, five factors were examined: (1) location of the household, (2) access to infrastructure, (3) changes in rice prices, (4) peace situation, and (5) initial household endowments. The most important finding is that impacts of the five factors vary significantly across households belonging to
different income groups--the rich benefit more than the poor. This calls for an
effective policy intervention in targeting the poor.
