It's unclear what the effects of a basic income would be in an undeveloped country.

For example, if a poorer country raised minimum wage too much it could destroy the economy whereas the same raise in a more developed country will have better short term effects.

This could end up being unethical economic experimentation.

That's a bad example since raising minimum wage increases the cost of doing business. Artificially changing the cost of business inputs causes problems in the economy - not the fact that people are earning more money.

Giving people money allows them to buy livestock, supplies for their children or food and shelter. This will help to improve their quality of life and spur the local economy. I'm hard pressed to see how this could be considered unethical.

This is true, but given the evidence we do have (GiveDirectly's previous programs and previous basic income programs in developed countries) I see no reason to believe the effects will be anything but positive.

I think more scary is the macroeconomic effects of a large amount of cash on currencies and prices. $30m is a relatively small amount (compared to a total GDP of e.g. more than $50b for Kenya), but of concentrated in poor areas could have unintended effects.
