**Summary:**

Maybe this post should be titled "Erratum" or "corrigendum". I have an example in my paper last year in which wage frontiers are supposed to vary with two parameters. One is the markup in the "iron" industry. And the other is σ t. The example should be as in Table 1. All the theory and the visualizations in the paper work out with this example.

Maybe this post should be titled "Erratum" or "corrigendum". I have an example in my paper last year in which wage frontiers are supposed
to vary with two parameters. One is the markup in the "iron" industry. And the other is σ *t*. The example should be
as in Table 1. All the theory and the visualizations in the paper work out with this example.
