We consider competition among sellers when each of them sells a portfolio of distinct products to a buyer having limited slots. We study how bundling affects competition for slots. Under independent pricing, equilibrium often does not exist and hence the outcome is often inefficient. When...

In this paper we study, as in Jeon-Menicucci (2009), competition between sellers when each of them sells a portfolio of distinct products to a buyer having limited slots. This paper considers sequential pricing and complements our main paper (Jeon- Menicucci, 2009) that considers simultaneous...

This paper identifies strategies to build a library consortium from a long term point of view. Contrary to the conventional wisdom to build a consortium around groups of homogenous institutions (Davis, 2002), we find that libraries with similar preferences are likely to lose from building a...

Electronic academic journal websites provide new services of text and/or data mining and linking, indispensable for efficient allocation of attention among abundant sources of scienti…c information. Fully realizing the benefi…t of these services requires interconnection among websites....

While vertical integration is traditionally seen as a solution to the hold-up problem, this paper highlights instead that it can generate hold-up problems — for rivals. We first consider a successive duopoly where competition among suppliers eliminates any risk of hold-up; downstreamfirms thus...

We study bundling by a dominant multi-product rm facing competition from a rival multi-product rm. Compared to competition under independent pricing, competition under pure bundling reduces (increases) each rm's prot for low (high) levels of dominance, while for intermediate levels of dominance,...

The renegotiation of regulatory contracts is known to prevent regulators from achieving the full commitment efficient outcome in dynamic contexts. However, assessing the cost of such renegotiation remains an open issue from an empirical viewpoint. To address this question, we fit a structural...

The paper makes two related contributions. First, and in contrast with the rich body of literature on collusion with (mainly perfect) substitutes, it derives general results on the sustainability of tacit coordination for a class of nested demand functions that allows for the full range between...
