Intervention(s)
The intervention consists of randomized subsidies for credit purchase contracts of solar lamps. Each firm owner in the down payment treatment group faces a subsidized contract with a random amount of subsidy for the down payment, and a market contract. Each firm owner in the tailored treatment group faces two subsidized contracts with a random amount of subsidy applied to either the down payment or the repayment. Each firm owner in the control group faces a market contract and another contract clearly dominated by the market contract. Each respondent chooses to adopt one or none of the two contracts.
The market contract is down payment of 800 KES and a daily repayment of 24 KES for 390 days, or equivalently, a weekly repayment of 168 KES for 56 weeks.
In the down payment treatment group, the random amount of subsidies are drawn from {95, 189, 284 , 378, 473} KES. The subsidy amount is directly subtracted from the market contract down payment of 800 KES.
In the tailored treatment group, the random amount of subsidies are drawn from {95, 189, 284 , 378, 473} KES. For the contract with down payment subsidy, the subsidy amount is directly subtracted from the market contract down payment of 800 KES. For the contract with repayment subsidy, the subsidy is applied to the first 4 week weekly payments according to the following arrangement: Subsidy of 95 is applied by offering 1 free day for every 6 daily payments made, up to 4 times. Subsidy of 189 is equivalent to 2 free days for every 5 daily payments made, up to 4 times. Subsidy of 284 is equivalent to 3 free days for every 4 daily payments made, up to 4 times. Subsidy of 378 is equivalent to 4 free days for every 3 daily payments made, up to 4 times. Subsidy of 473 is equivalent to 5 free days for every 2 daily payments made, up to 4 times. The equivalence is drawn by assuming no skipping and a discount rate used by the solar company.
