This paper has a two-fold contribution, first we demonstrate the relationship of spatial, temporal and residual yield risk estimated from a two-way panel random effects model to asymmetric information with an optional unit provision in the federal crop insurance program. Second, the yield risk components are incorporated in a discrete choice model to examine the presence of asymmetric information due to potential yield switching with optional unit provisions. Empirical application to 1998 U.S. cotton crop insurance data reveals the presence of asymmetric information with optional unit provisions.
