In this paper we investigate the existence of a two-tier medical system in the German acute care hospital sector using data from a survey of 483 German hospitals. The focus of our analysis lies on the impact of hospital concentration on the probability of discrimination of patients with...

We analyze how consumer preferences for one-stop shopping affect the bargaining relationship between a retailer and its suppliers. One-stop shopping preferences create "demand complementarities" among otherwise independent products which lead to two opposing effects on upstream merger...

This paper analyzes vertical integration incentives in a bilaterally duopolistic industry where upstream producers bargain with downstream retailers on terms of supply. In the applied framework integration does not affect the total output produced, but it affects the distribution of rents among...

Consumers increasingly prefer to bundle their purchases into a single shopping trip, inducing complementaries between initially independent or substitutable goods. Taking this one-stop shopping behavior into account, we show that slotting fees may emerge as a result of a rent-shifting mechanism...

We analyze the effects of synergies from horizontal mergers on managerial incentives. In contrast to synergies, efficiency gains resulting from managerial effort are not merger specific, i.e., they may be realized by all firms before and after a merger. We show that synergies suppress managerial...

We analyze the effects of synergies from horizontal mergers in a Cournot oligopoly where principals provide their agents with incentives to cut marginal costs prior to choosing output. We stress that synergies come at a cost which possibly leads to a countervailing incentive effect: The merged...

Financial constraints are an important impediment to the growth of small businesses. We study theoretically and empirically how the financial constraints of agents affect their decisions to exert effort, and, hence the organizational decisions and growth of principals, in the context of...

Financial constraints are considered an important impediment to growth for small businesses. We study theoretically and empirically the relationship between the financial constraints of agents and the organizational decisions and growth of principals, in the context of franchising. We find that...

We develop a model for two-sided markets with consumers and producers, who interact through a platform. Typical settings for the model are the market for smartphones with phone users, app producers, and smartphone operating systems; or the video game market with game players, video game...

This model discusses mobile network operators' (MNOs) incentives to invest in their network facilities such as new 4G networks under various regimes of data roaming charge regulation. Given an induced externality of investments (spillovers) due to the roaming agreements it will be shown that...
