For groups that must make several decisions of similar form, we define a simple and general mechanism that is designed to promote social efficiency. The mechanism links the various decisions by forcing agents to budget their representations of preferences so that the frequency of preferences...

We study Bayesian mechanism design in situations where agents' information may be multi-dimensional, concentrating on mechanisms that lead to efficient allocations. Our main result is that a generalization of the well-known Vickrey-Clarke-Groves mechanism maximizes the planner's "revenue'' among...

Die Studie „Wertschaffendes Umweltmanagement“ betrachtet den Zusammenhang zwischen Umweltaspekten und Unternehmenswert. Hierbei bezieht sie erstmals zwei unterschiedliche, sich ergänzende Bewertungsverfahren ein: Sie nimmt erstens das Konzept des Environmental Shareholder Value auf und...

Limited liability debt financing of irreversible investments can affect investment timing through an entrepreneur's option value, even after compensating a lender for expected default losses. This non-neutrality of debt arises from an entrepreneur's unique investment opportunity, and it is shown...

The role that Bernanke’s Bad News Principle plays in the modern theory of investment under uncertainty is analyzed. The analysis shows that the actual investment dilemma is that by delaying investment firms trade off a higher present value of earnings for a lower present value of the...

This paper analyzes an agent¡¯s option exercise decision under uncertainty. The agent decides whether and when to do an irreversible activity. He is tempted by immediate gratification and suffers from self-control problems. This paper adopts the Gul and Pensendorfer self- control utility...

We present the Progressive Second Price auction, a new decentralized mechanism for allocation of variable-size shares of a resource among multiple users. Unlike most mechanisms in the economics litterature, PSP is designed with a very small message space, making it suitable for real-time market...

We study the formation of coalitions that provide public goods to members. Individuals are linked on a tree graph and those with similar preferences are connected on the tree. We present a solution that selects allocations belonging to the coalition structure core and that are also envy-free.

This paper, forthcoming in Journal of Economic Surveys, provides an elementary, non-technical, survey of auction theory, by introducing and describing some of the critical papers in the subject. (The most important of these are reproduced in a companion book, The Economic Theory of Auctions,...

Agent-based computational economics (ACE) is the computational study of economies modeled as evolving systems of autonomous interacting agents. Starting from initial conditions, specified by the modeler, the computational economy evolves over time as its constituent agents repeatedly interact...
