We start by describing the benchmark case with the following parameter values, as summarizedby Table 1.We also present the results for x = 0.05 and x = 0.1, holding the other parameter values constantat the benchmark levels. We also allow k to vary from 0 to ∞, holding the other parameter valuesconstant at the benchmark levels, and allow r to vary from 0 to ∞, holding the other parameter valuesconstant at the benchmark levels.
