		| Although the home-market effect has become one of the most important concepts in both trade theory and the new economic geography, it lacks a compelling graphical representation. 
The purpose of this note is to offer such a representation.
We will decompose the home-market effect into two steps: a short-run
response to population shift, creating entry-stimulating excess profits (in the short run) for firms of the country that experiences a population gain, and a further round of entries into the monopolistic sector of the expanding country induced by exits in the foreign industry. |
