Resumo

We develop an experience based premium rate discount system in crop insurance able to cope with adverse years when high losses happen within some return period. Technically, it consists of the application of Tweedie’s model and regressions embedded in a mean discount model. We also develop our system using censored regression (Tobit model) and compare results. The proposed rating system should be able to cope with those years that destabilize the technical result caused by chronic premiums insufficiency. We use data taken from the Spanish “table grape” line of business to exemplify the methodology.
