We study multi-object auctions where agents have private and additive valuations for heterogeneous objects. We focus on the revenue properties of a class of dominant strategy mechanisms where a weight is assigned to each partition of objects. The weights influence the probability with which partitions are chosen in the mechanism. This class contains efficient auctions, pure bundling auctions, m...

We analyze mixed bundling in two-sided markets where installed base e ects are present and nd that the pricing structure deviates from traditional bundling as well as the standard twosided markets literature|{we determine prices on both sides fall with bundling. Mixed bundling acts as a price discrimination tool segmenting the market more e ciently. Consequently, as a by-product of this price d...

In this paper we consider the strategy of stochastic bundling, which we define as a selling strategy in which firms guarantee a consumer will receive a good, but do not guarantee which one it will be. First we derive a new condition that ensures the optimality of stochastic bundling when there is no secondary market. Then we graphically consider the conditions under which stochastic bundling ma...

Graph streams have been extensively studied, for instance, for data mining and for stream reasoning, while a fairly limited number of studies have been conducted on visualizations. Recently, edge bundling methods has been extensively investigated to reduce visual clutter in large graph visualizations, however, have focused on static graphs. This paper presents a new framework, namely StreamEB, ...

I thank the participants for their comments while claiming responsibility for any errors and omissions. 1 This work also provides references to the earlier literature. 2 Introduction There is a substantial literature on commodity bundling. A seminal point of departure for th...

Let X = Γ\G/K be a compact locally symmetric space. In this paper we establish a version of the Selberg trace formula for non-unitary representations of the lattice Γ. On the spectral side appears the spectrum of the “flat Laplacian” ∆, acting in the space of sections of the associated flat bundle. In general, this is a non-self-adjoint operator.

In this paper we investigate the tactical problem of pricing a bundle of products when the underlying valuations of the bundle components are dependent. We use copula theory to model the joint density of reservation prices and provide analytical derivations for the prices under different bundling strategies and sharp bounds for the profit function. We discover that when only the bundle is offer...
