This study examines the impact of weather on the yields of seven major crops in Taiwan based on pooled panel data for 15 prefectures over the 1977-1996 period. The unit root tests and maximum likelihood methods involving a panel data model are explored to obtain reliable estimates. The uncertain yield outcome is incorporated into a discrete stochastic programming model to address a comparison between sector analysis with and without considerations of a crop insurance policy under different climate change scenarios. Simulation results suggest that crop insurance may stabilize revenues and protect farmers from exposures to increasing weather-related risk.
