Weather extremes, agriculture and the value of weather index insurance

The Geneva Risk and Insurance Review, 2023
AbstractThis paper evaluates the potential value of a weather index insurance for the agriculture sector in an high income country (Germany). In our theoretical analysis we model an index insurance, a loss-based insurance market as well as a combination of both kinds of insurance and compare the resulting expected utility of a risk averse crop farmer ...
