Anubhab, Ed and Xinda are cotton farmers in the village of  Qacha’s Nek in rural Lesotho. They each have zero wealth

(W=0), so their consumption is equal to the income they earn from their economic activity. Each of them must choose

one (and only one) of the following three activities:

Activity 1: Full time farming with UKM08 cotton seeds: A farmer should work full time (7 days per week) on their

farm if they are cultivating UKM08 cotton. Working full time a farmer has a 50% probability of having a GOOD

harvest and earning income of \$420 and a 50% chance of having a BAD harvest and earning only \$60.

Activity 2: Full time farming with UK92 cotton seeds: UK92 variety is very well adapted to local weather conditions

and thus has no risk. If a farmer works full time she will earn \$210 with certainty.

Activity 3: Part-time farming with UKM08 cotton seeds: In this third activity, a farmer plants UKM08 variety cotton

seeds  and  works  Monday  through  Thursday  on  his  farm  and  he  works  Friday  through  Sunday  as  a  construction

worker in the nearby city of Geita. Since he is not able to work full-time on the farm, it is more likely that he suffers

damages from pests or bad weather. Specifically, the probability of having a GOOD cotton harvest and earning \$420

drops to 25%, while the probability of having a BAD harvest and earning only \$60 increases to 75%. The individual

also

earns \$60 with certainty as a construction worker (i.e., he earns \$60 in addition to his farm income under both

a GOOD and a BAD harvest).
