Actuarial Implication of Structural Changes in El Niño-Southern Oscillation Index Dynamics

The influence of climate variability on agricultural production and financial risks faced by an individual or an institution has been the center of the public discussion in the recent years. The changing weather patterns and environmental conditions could cause substantial unpredicted economic loss. Failure to capture the changing climate would underestimate the insurance contract’s expected indemnity and further create a major obstacle for insurance sectors. In this paper, we undertake a case study of El Niño-Southern Oscillation Index insurance for coastal Peru proposed by Skees. We examined the behavior of El Niño dynamics and found El Niño indices are changing over time. A class of generalized autoregressive conditional heteroskedasticity (GARCH) - family process that allows the disturbance variance to vary over time is used to design and rate the El Niño-Southern Oscillation Index insurance contract.
