Isotropic
From Hobson's Choice
The characteristic of being the same everywhere; as, for example, a fluid or gas in an enclosed chamber.
Within a small chamber, ambient gases will maintain the same pressure everywhere; the density will be the same, as well as resistance to motion. In contrast, the contents of a bucket of dirt will be very different from point to point inside the bucket.
As a metaphor, "isotropic" is used to refer to neoclassical/DGE conceptions of the economy. Under such schools of economics, the economy is represented as a uniform space in which transactions take place unimpeded by local constraints, such as what institutions happen to prevail.
