| Failure of integrability is shown to cause path-dependence of willingness-to-pay measures of welfare change. Using the linear expenditure system, effects of failure of integrability are negligible (substantial) for estimating income (price) elasticities. For single price changes, Hausman's approach to calculating willingness to pay from ordinary demands becomes subject to excessive errors of estimation. For multiple price changes, calculations of willingness to pay become path dependent. The empirical approach of Vartia to calculation of willingness to pay for multiple price changes thus involves an arbitrary choice of path. Furthermore, the Willig results justifying consumer surplus approximation fail. |

| The primary goal of emergency food aid after an economic shock is often to bolster short-term food and nutrition security. However, these transfers also act as insurance against other shock effects, such as destruction of assets and changes in economic activity, which can have lasting deleterious consequences. Although existing research provides some evidence of small positive impacts of timely food aid disbursements after a shock on current food consumption and aggregate consumption, little is known about whether these transfers play a safety net role by reducing vulnerability and protecting assets into the future. We investigate this issue by exploring the presence of persistent impacts of two major food aid programs following the 2002 drought in... |

| We evaluate the effectiveness of targeting for Brazil's Bolsa Alimentação, a nutrition-oriented cash transfer program conditioned on beneficiary participation in health activities. Geographic targeting of program funds relied on adjusted estimates of municipality child stunting prevalence, or a malnutrition map. This evaluation provides new estimates of municipality child stunting prevalence for Brazil. The improved estimates indicate moderate budgetary misallocation from geographic targeting. However, when geographic targeting errors are combined with those arising from an inconsistency between geographic and household targeting objectives, undercoverage of children at greatest risk of stunting is potentially large. |
