Using short-run expenditures from household surveys as a proxy may create attenuated estimates of the impact of permanent income on economic outcomes. We use repeated observations to calculate reliability ratios and estimate errors in variables regressions of the impact of income on nutrition....

Whether the poor face higher food prices is unsettled in the literature after more than four decades of study. While unit values from household surveys suggest higher prices for the poor, outlet surveys typically find food prices varying with store type but not with neighborhood income. Most...

Survey reports of zero expenditure result from either genuine non-consumption, or purchases undertaken too infrequently to observe during a survey, with hidden consumption from stocks. Infrequent purchase models rely on untested hypotheses to distinguish these types of zeros. We test such models...

Asian governments intervene in the world rice market to protect domestic consumers. Whether consumers are nutritionally vulnerable depends on the elasticity of calories with respect to rice prices. Common demand models applied to household survey and market price data ignore quality substitution...

Cluster-corrected standard errors are widely used but may sometimes be inappropriate since household surveys are increasingly geo-referenced. Compared with the appropriate spatial error models that use details on exact locations, cluster corrections impose untested restrictions on spatial...

If relative prices of goods within a commodity group are constant, Hicksian separability lets the price of a single good represent the group price level. This is relied on by price questionnaires used in household surveys. Methods of estimating demand systems from household survey data also rely...

If relative prices of goods within a commodity group are constant, Hicksian separability lets the price of a single good represent the group price level. This is relied on by designers of price questionnaires used in household surveys and by methods of estimating demand systems from household...

Whether there is a poverty penalty, in terms of food prices, is unsettled in the literature after more than four decades of study. Unit values from household surveys suggest that prices vary with income while outlet surveys typically find food prices varying with store type but not with...
