Economic systems are dynamic entities, and the nature and consequences of changes that take place in these systems are of considerable importance. Regional economics represents a framework within which spatial character of an economic system can be understood. Regional economics is a relatively young branch of economics. Its late start exemplifies the regrettable tendency of formal professional disciplines to lose contact with one another and to neglect some important problem areas that require a mixture of approaches. Scholarly peer review is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The work may be accepted, considered acceptable with revisions, or rejected. Peer review requires a community of experts in a given (narrowly defined) field, who are qualified and able to perform reasonably impartial review.
