We consider general asset market environments in which agents with quasilinear payoffs are endowed with objects and have demands for other agents' objects. We show that if all agents have a maximum demand of one object and are endowed with at most one object, the VCG transfer of each agent is...

We investigate Groves mechanisms for economies where (i) a social outcome specifies a group of winning agents, and (ii) a cost function associates each group with a monetary cost. In particular, we characterize both (i) the class of cost functions for which there are Groves mechanisms such that...

The purpose of this paper is to consider if Amazon’s increase in private label brands is the tipping point for transforming the e-commerce giant into a monopoly. To lay the foundation, we initially explore the culture, leadership, and business practices which are unique to Amazon that enabled...

We explore the equivalence of local incentive compatibility (LIC) (Carroll (2012)) and incentive compatibility (IC) in non-convex type-spaces. We provide a sufficient condition on a type-space called minimal richness for the said equivalence. Using this result, we show that LIC and IC are...

We explore the relation between different notions of local incentive compatibility (LIC) and incentive compatibility (IC) on ordinal type-spaces. In this context, we introduce the notion of ordinal local global equivalent (OLGE) and cardinal local global equivalent (CLGE) environments. First, we...

In 2019 the Department with responsibility for household waste (HHW) policy in Ireland will commence a review of its 2012 Policy. That review – as anticipated in the 2012 Policy – will rely on the research and analysis of the Competition and Consumer Protection Commission (CCPC) on the state...

We analyze a drastic price increase in the German auction market for reserve power, which did not appear to be driven by increased costs. Studying the market structure and individual bidding strategies, we find evidence for collusive behavior in an environment with repeated auctions, pivotal...

Renegotiation is a common practice in procurement auctions which allows for post-auction price adjustments and is nominally intended to deal with the problem that sellers might underestimate the eventual costs of a project during the auction. Using a combination of theory and experiments, we...

This paper studies combinatorial auctions with budget-constrained bidders from a mechanism design perspective. I search for mechanisms that are incentive compatible, individually rational, symmetric, non-wasteful and non-bossy. First focusing on the greedy domain, in which any increase in a...

I present two modifications of the Vickrey-Clark-Groves mechanism to accommodate bidders' budget constraints in the combinatorial auction setting and show that they are Pareto-Optimal and (partially) incentive compatible in certain domains.
