Urban Economics 8
Consider the example shown in Tables 21 and 22. Suppose a single number changes: The shirt output per hour in the North is four shirts instead of six shirts. To specialize, a North household switches one hour from bread to shirts, and a South household switches two hours from shirts to bread. The exc
