An upshot from the last post. Markets can adjust by price, or by quantity. Economics usually assumes that they do both simultaneously, although the maths usually doesn’t work that way. There is no reason I can think of to prefer either mode of adjustment a priori, but practical applications will usually show that one or the other would be better.
In the radical view that markets are institutions that are defined by the societies that create them, it is a very important question whether a new one (or an old one undergoing change) will tend to adjust price-first or quantity-first.
