Abstract
This paper investigates whether estimating vulnerability to poverty using consumption expenditures and food calorie intake provide consistent policy implications based on the vulnerability as expected poverty framework. Feasible generalized least square (3FGLS) method is applied on large data-set of about 90,000 households in the Punjab province, Pakistan. The results indicate that the analysis based on the two approaches results in considerable geographic differences in the distribution of vulnerability to poverty. The implication of our results is that anti-vulnerability interventions based on monetary indicators of poverty will penalize those regions with low monetary poverty but high nutrition poverty.

Notes
Tehsil is the administrative unit of the district. There are 9 divisions, 36 districts, 150 tehsils/towns in the Punjab.
Imai et al. (2010) suggest the need of using large sample size if vulnerability is to be measured from cross-sectional data-set.
We use market exchange rate to express Pakistani rupee in terms of US dollar. For a detailed discussion refer to Freeman’s (2009) critique on the superiority of Purchasing Power Parity (PPP) exchange rate over market exchange rate.
MICS-data contain information on the four shocks that are Fever, TB, Hepatitis, and 2010 Flood.
