European Economic Growth: Comments on the North-Thomas Theory.

The article comments on the paper "An Economic Theory of the Growth of the Western World," by professors Douglas C. North and Robert Paul Thomas. The paper is related to European economic growth. The theory proposed by North and Thomas relies heavily upon three components. The first is a model for cyclical fluctuations in the pre-industrial economic life of Europe. This model defines the relative changes in the cost of land and labor as changes in population alter the ratio between the two. It incorporates the relative elasticities which have been found in the supply and demand curves for foodstuffs as opposed to those for raw materials and industrial products. North and Thomas then elaborate this last observation into the second major element of their model, a "theory of institutional change." The shifts in factor proportions so heightened the possibilities of profit from production for the market that they exceeded the costs of the institutional innovations needed to change the organization of production and distribution of income. The result was the steady introduction of "secondary" institutional changes such as enclosures, joint-stock companies, government support of certain guilds, and regulation of quality.
