Persistence of leadership in product innovation
Article Abstract:
A study was conducted to examine a vertical product differentiation model. The model presents three companies with different market share patterns. The shares lead to an equilibrium condition where new product introduction strategies vary for the firms. Results show that companies innovate through 'learning by doing.' The results support the evolution of stable market shares after a series of business innovations.

Measuring market power and cost-efficiency effects of industrial concentration
Article Abstract:
Appelbaum's (1982) model for measuring market power in a homogenous oligopoly is extended to analyze the market-power and efficiency effects of increased concentration in factor markets. Application of the model to the beef packing industry shows that increased buyer concentration has resulted in additional costs. However, the benefits of increased concentration are sufficient to cover these costs.
