Expenditure elasticity and consumption inequality in rural China.

Consumption inequality is a matter of great concern. However, measurement error always appears when doing so. To handle this, this paper uses a method based on Engel expenditure elasticity proposed by Aguiar and Bils. The results show that consumption inequality in rural China based on Engel expenditure elasticity is smaller than the income inequality and consumption inequality calculated by the ratio of high-income to low-income households.
