(Income Polarization of Korean Farm Households : A Comparison by Age of Farm Manager and Income Source)

This study analyzes the income polarization of Korean farm households by different age groups of farm managers and income sources, using the EGR and DER polarization indexes. The data were drawn from the Farm Household Economy Survey for the years 2003-2009. The major findings are as follows: (1) Farm household income has been rapidly trending toward polarization since the mid-2000s; this polarization is most apparent in farm income as compared to non-farm income. (2) With the rising share of nonfarm income out of total household income, the polarization of farm household income became increasingly attributable to that of non-farm income. (3) When decomposed by age of the farm manger, between-group polarization explains three-fourths of the overall polarization; regarding within-group polarization, it was most apparent for farm households whose managers are in their 40s as well as those with mangers aged 70 or over.
