This paper studies the incentive by a single firm in a differentiated goods duopoly to engage in cost-reducing innovations and how this incentive is affected by the level of competition in the product market. It is found that a firm's innovation effort has a U-shaped relationship with the level...

This paper studies an effect of a horizontal merger where a product consolidation by the merged firm may alter the substitutability in the industry. We show that as the number of firms in the industry increases, this type of merger becomes profitable for merging firms, while unprofitable for...

I investigate R&D efforts for process innovation in a monopoly with uncertain demand. Two different models are proposed, where either (i) the reservation price is affected by an additive shock and the marginal production cost is increasing, or (ii) a multiplicative shock on the slope of demand...

Licensing a new technology implies introducing competition into the market. This has a negative effect on the profit of the incumbent if the demand remains unchanged. However, because of the novel content of an innovation, consumers may have different perceptions of the value of a good depending...

This paper studies the stability of mergers between firms in a Cournot market. Unlike most existing works, we consider a demand structure where the substitutability between firms is asymmetric. We specifically focus on the stability of the grand coalition by analyzing the core allocation. The...
