Conjectural variation models are popular in empirical research as they infer the degree of market power from real data. IO-theorists, however disapprove it for lack of theoretical foundation arguing that dynamic reactions are forced into a static model with the strategy space and time horizon...

We investigate the entry timing and location decisions under market-size uncertainty with Brownian motions in a continuous-time spatial competition duopoly model a la d'Aspremont et al. (1979). Under a sequential equilibrium, the threshold of the follower non-monotonically increases in...

We study a discrete time dynamic game of price competition with spatially differentiated products and price adjustment costs. We characterise the Markov perfect and the open-loop equilibrium of our game. We find that in the steady state Markov perfect equilibrium, given the presence of...

We model a vertically differentiated duopoly with quantity-setting firms as an extended game in which firms noncooperatively choose the timing of moves at the quality stage, to show that at the subgame perfect equilibrium sequential play obtains, with the low-quality firm taking the leaders role.

We provide a simple model to investigate decisions on vertical integration/separation. The key feature of this model is that more than one input is required for the final products of the local downstream monopolists. Depending on their cost structure, downstream firms' decisions on vertical...

Both mergers and innovation are central elements of a firm s competitive strategy. However, model-theoretical analysis of the merger-innovation link is sparse. The aim of this paper is to analyze the impact of mergers on innovative activities and product market competition in the context of...

Double marginalization causes inefficiencies in vertical markets. This paper argues that such inefficiencies may be beneficial to final consumers in markets producing vertically differentiated goods. The rationale behind this result is that enhancing efficiency in high-quality supply chains...

We examine merging firms' additions and removals of products for a sample of 66 mergers across a wide variety of consumer packaged goods markets. We find that mergers lead to a net reduction in the number of products offered by merging firms. Merging firms tend to both drop and add products at...

We model the value chain of Carbon Capture, transport and Storage (CCS) by focusing on the decisions taking by actors involved in either capture, transport or storage of CO2. Plants emitting CO2 are located along a Salop circle. If these invest in carbon capture facilities, the captured CO2 is...

This paper considers the effects of an interim performance evaluation on the decision of a principal to delegate authority to a potentially biased but better informed agent. Assuming the agents ́outside option to be determined by market beliefs about their type, interim evaluations (a) provide...
