When profits are pursued by geographic interchange of goods, so that commerce for profit becomes the central mechanism of the system, we usually call it "commercial capitalism." In such a system goods are conveyed from ares where they are more common (and therefore cheaper) to areas where they are less common (and therefore less cheap). This process leads to regional specialization and to division of labor, both in agricultural production and in handicrafts.

Inflation, especially a slow steady rise in prices, encourages producers, because it means that they can commit themselves to costs of production on one price level and then, later, offer the finished product for sale at a somewhat higher price level. This situation encourages production because it gives confidence of an almost certain profit margin.
