Description: Research report sponsored by SOA to model and compare projected costs of different proposals for a Medicare prescription drug coverage plan. 3 types of costs are studied: net benefit cost estimates per member per month, continuance table data, and projected annual costs to the government over 10 years for two selected plan designs.

Description: This paper addresses rainfall insurance using financial derivatives. Usual modeling is done for temperature related products. The authors gathered rainfall data in Mexico City over a period of five decades. This showed that the time series data is stationary and normally distributed. Therefore, the authors applied a closed-form solution to value swaps, calls and puts, with and without limits. The model can be used for practical purpose of pricing rainfall derivatives. From Actuarial Research Clearing House, 2006.

Description: The article describes the key components of actuarial model, leading practices in designing them, and characteristics of well-built models.
