Mathematical Modeling of Agricultural Insurance Pricing in Morocco

“…Consequently, if 𝑋 0 > 0, then X(t)>0 for all t >= 0. In conclusion, all solutions of 𝑆(𝑡), 𝑇(𝑡), 𝐺(𝑡), 𝑎𝑛𝑑 𝐾(𝑡) with a positive initial condition, are positive, 𝑋(𝑡)𝜖𝑅 + 4 .…”

“…Initially, agricultural insurance is the insurance that allows farmers to protect themselves against various losses for instance the loss of production and loss of income [4]. The insurable risks can be: adverse climatic conditions (drought, excessive rainfall, floods, storms, frost, hail, sunburn, snow, wind), pests and epidemic diseases, fire or any other defined risks and other climatic phenomena [5,6].…”

“…Nevertheless, they limited their study to comparing the variable reimbursement schemes to fixed reimbursement schemes without proposing any method of calculating the premium under index-based crop insurance. In a different perspective from the above, based on the famous principle of damage insurance premium, [4] proceeded in his article to determine the pure premium to be paid by the Senegalese farmer insured against conventional risks by using the general linear model (GLM) to determine the frequency and severity according to the different types of risks to which farmers are exposed [4]. He showed that the number of claims follows a negative binomial zero-inflation law and the cost follows a log-normal distribution [4].…”

This literature review revealed that crop insurance pricing is based on the assumptions of the yield distributions that can affect the estimation of future yields.…”
