Update To Example In Vienneau (2019)

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.

Table 1: Technology for Producing Steel and Corn

Input	Industry
	Iron	Corn
		Alpha	Beta
Labor	a0,1 = 1	aα,0,2(t) = (5191/5770) e(1/10) - σ t	aβ,0,2 = 305/494
Iron	a1,1 = 9/20	aα,1,2(t) = (1/40) e(1/10) - σ t	aβ,1,2 = 3/1976
Corn	a2,1 = 2	aα,2,2(t) = (1/10) e(1/10) - σ t	aβ,2,2 = 229/494
