Abstract
Although crop insurance is an important risk management strategy for farmers to secure their income stability, the adoption of crop insurance has been extremely low. Recent studies have highlighted the significant role of pay-at-harvest premiums in take-up rate for crop insurance. However, pay-at-harvest faces a major challenge of default. To address such issue, this research focuses on a key scientific question: “What is the best timing of premium payments to boost farmers’ demand for crop insurance and mitigate payment default?”. To answer this question, this research evaluates and compares the causal impacts of different timings of premium payments on farmers’ take-up of crop insurance (rice insurance) and payment default using a field experiment in Vietnam. The field experiment is carried out in 41 Village Savings and Loan Associations (VSLAs) over two rice seasons to examine the persistent impacts of the interventions. The combination of delayed premium payments through VSLAs raises the social cost of default and reduces transaction cost as premiums are collected via VSLAs.

Interventions

Intervention(s)
a. Pay-up-front (control): Farmers are requested to pay premiums when they decide to purchase crop insurance at the beginning of the season.
b. Pay-at-harvest (treatment 1): Farmers are allowed to pay premiums (plus 1% interest per month) at the end of the season although they decide to purchase crop insurance at the beginning of the season. The added interest rate is based on VSLAs’ borrowing interest rate.

Experimental Design

Experimental Design
This research includes 5 stages. In the 1st stage, a pilot and baseline survey are conducted to collect basic information of 41 VSLAs and 800 farmers. This information is used to assign 41 VSLAs into different treatment arms using stratified randomization technique. Then, VSLAs’ leaders are trained in the 2nd stage to be able to make lists of participants, collect premiums, and distribute insurance contracts.
My field experiment is carried out over two seasons (3rd stage, 4th stage, and 5th stage) to examine the persistent impacts of the treatments. In each season, insurance educators introduce crop insurance to farmers through VSLAs’ meetings at the beginning of the season. After that, farmers have 2 weeks to purchase the insurance. Farmers in pay-up-front group (control group) pay premiums within these two weeks. Farmers in delayed-payment groups pay premium (plus interest) at the end of the season or other delayed timings, respectively. Follow-up survey is conducted at the end of each season to obtain four outcomes: take-up decision, default decision, agricultural investments, farmers’ income and expenditure.
