Notes: The program costs reported in Lines (1) to (6) were provided by CAWTAR, the NGO in charge of implementation in 2018. IMF estimates of inflation are used to express values in 2021 Tunisian Dinars. In Line (7), we inflate the total costs to year 2 using a social discount rate of 5% per year. In Line (8), the Year 2 ITT effect on yearly consumption is obtained by estimating equation (1) with a measure of household yearly consumption. The ITT effect on yearly consumption in year 1 (Line 9) is assumed to be equal to the ITT effect on yearly consumption in year 2 (line 8). In Line (10), we assume a social discount rate of 5% to estimate the value of perpetuity of the ITT effect on yearly consumption (= _−_ 883 _/ln_ (0 _._ 95)). In Line (12), the ITT effect on the value of animals is taken from Table 1. In Line (13), the ITT effect on the value of household assets is estimated using equation (1) with a measure of the value of household assets. The unit-value of each asset is estimated using the median replacement value reported in the baseline survey, subject to data availability. In Line (14), the ITT effect on the total value of assets is estimated using equation (1) with a measure of the total value of assets, which is equal to the sum of the value of animals and household assets. In Line (15), the ITT effect on the total value of post-treatment consumption and assets is estimated using equation (1) with a measure of total benefits equal to the sum of the total value of post-treatment consumption and the value of assets.
