Markets are intersections of buyers and sellers brought together to exchange goods and services most efficiently, so the theory goes. In fact, markets are also connected to barter and exchange and to their underlying value: resourcefulness. We look at Nina Katchadourian and her artwork made on airplanes ("Seat Assignment") as an example of resourcefulness, Caroline Woolard’s Work Dress as an example of barter, and Elizabeth Cleland’s exhibition as an example of equivalencies created by markets. We introduce supply and demand, how the graphs are constructed, and how to think about shifts in supply and demand.
