The authors show how the transformation loci in the specific factors model (capital specificity) and the Heckscher-Ohlin-Samuelson model (capital mobility) can be rigorously derived and easily compared by using geometric techniques on the basis of Savosnick geometry. The approach shows directly that the transformation locus with capital…

The author argues that they are incorrect in their assertion because the market they refer to is an asymmetric two-sided market in which individuals are only allowed to decrease…

As long as the instructor makes that assumption clear to students, the costs of making the changes recently suggested by X. Henry Wang and Bill Z. Yang in…
