On May 5, 2012 report on «How does the market size affect the product line scope? The case of a closed economy» by Senior Research Fellow of the MSSE Philipp Uschev.
We propose a model of monopolistic competition with multi-product firms, choosing their product line. Firms bear costs of three kinds: variable production costs, fixed costs of creating a variety (like R&D) and costs of scope, i.e., of the product line length. When the market size (population) increases, the overall variety always increases. The firms’ product line and price increase (decrease) when the elasticity of substitution increases (decreases), whereas the firm size (output) reacts oppositely (when both cost functions are strictly convex). This suggests a theoretical rationale for cross-countries differences in the size and scope of firms, or for possible consequences of trade liberalization.
