All 12 ratios are much higher than the 2.4 estimated for GiveDirectly’s cash transfers to poor households in Kenya.
2.4 refers to the integral of the increase in local real GDP over the 29 months after the transfer as a fraction of the transfer. The integral of an investment in global stocks over 29 months as a fraction of the initial investment is 2.56 (= ((1 + 0.05)^(29/12) − 1)/LN(1 + 0.05)) for the annual real growth rate from 1900 to 2022 of 5 %. So, over 29 months, I think investing in global stocks increases the integral of global real GDP 1.07 (= 2.56/2.4) times as much as GiveDirectly’s cash transfers to poor households in Kenya increase the integral of local real GDP.
