This paper analyzes calorie and micronutrient consumption in Vietnam using the
recent household survey data collected in 2006. The data suggest that food insecurity is
still a major problem in Vietnam, with nearly 40 percent of the population being unable
to meet their calorie requirement. Employing nonparametric and parametric estimation
techniques, the paper examines the relationship between household calorie consumption
and per capita household expenditure in Vietnam. The analysis indicates a positive and
significant relationship between per capita expenditure and per capita calorie
consumption. The mean calorie elasticity is estimated to be between 0.21 and 0.31 by
the parametric method and 0.20 by non-parametric method. In addition, simulated
income and food price changes indicate that undernutrition is very responsive to
changes in income and food prices. This paper also estimates protein and micronutrient
elasticities, an area often overlooked in empirical studies. Estimates of expenditure
elasticities of micronutrients are high, ranging from 0.3 for iron and calcium, to nearly
0.7 for vitamin C and 0.8 for vitamin A. This implies that income growth leads to large
increase in household micronutrient intakes, particularly for vitamin intakes.
