This workbook contains our cost-effectiveness analyses.

On the "Moral weights and discount rate" tab, we've included GiveWell and conventional estimates for a few parameters. If you'd like to see how our results would change based on different inputs for these parameters, you can enter your own values in the "Anyone" column of this sheet, the select "Anyone" from the dropdown menu in the "Results" tab. To see the results for programs in specific countries, select a country from the dropdown menus in the "Results" tab.

Expanding the formula bar at the top of the page (by clicking and dragging the bottom boundary) may make it easier to read the contents of explanatory cells.
