Using a six year panel of results from the United Nation's Food and Agriculture Organization's Food Insecurity Experience Survey collected by Gallup World Survey, we investigate the relationship between food insecurity experiences and income. By applying Rasch modelling of context-specific item response and limited dependent variable econometrics, we estimate this relationship and draw comparisons across contexts. This is accomplished via analysis of the unobserved heterogeneity resulting from fixed effects, as well as country-group comparisons of what we define as a semi-elasticity of food insecurity experiences. Finally, we estimate the costs of alleviation for the moderate and severe food insecurity thresholds of food insecurity on a globally-comparable scale for 2017 and investigate differences in costs across countries in our sample. Our results are based on data surveyed with coverage of more than 90 percent of the world's population and is unique in its contribution to the body of comparative international food insecurity studies.
