Auctions with endogenous participation
2000We study endogenous-participation auctions where bidders only know the number of potential participants. After seeing their values for the object, potential participants decide whether or not to enter the auction. They may ... -
Corruption and auctions
2006We investigate how corruption affects the outcome of a first-price auction (bidding behavior, efficiency and the seller's expected revenue). The auctioneer approaches the winner to offer the possibility of a reduction in ... -
First-price auctions without affiliation
2006We give conditions for equilibrium existence in private value, symmetric, first-price auctions without affiliation assumptions. © 2005 Elsevier B.V. All rights reserved. -
Games with discontinuous payoffs: A strengthening of Reny's existence theorem
2011We provide a pure Nash equilibrium existence theorem for games with discontinuous payoffs whose hypotheses are in a number of ways weaker than those of the theorem of Reny (1999). In comparison with Reny's argument, our ... -
The general existence of extended price equilibria with infinitely many commodities
1994-08This paper deals with the existence of equilibria with infinitely many goods. Its main goal is to show that when restricted to the set of feasible allocations there exists an economically meaningful price (in the sense ... -
Incomplete markets, continuum of states and default
1998-01We show that when bankruptcy, subject to penalties, is allowed, it is possible to prove the existence of equilibrium in a model with a continuum of states without imposing any assumptions on ex-post endowments. -
Inconsequential arbitrage
2000-12We introduce the concept of inconsequential arbitrage and, in the context of a model allowing short-sales and half-lines in indifference surfaces, prove that inconsequential arbitrage is sufficient for existence of ... -
Increasing cones, recession cones and global cones
2000In this paper, we discuss and compare various cones used in the economics literature to analyze arbitrage in general equilibrium models with short selling. Our main result is that under certain conditions on an economic ... -
Infinite horizon incomplete markets with a continuum of states
1996In this paper we address existence of equilibria in an incomplete markets economy with countably many periods and a continuum of states at each node of the infinite tree. We consider two models: one where agents have to ... -
Inflation and income inequality: a shopping-time approach
2005-12Our work is based on a heterogenous agent shopping-time economy in which economic agents present distinct productivities in the production of the consumption good, and differentiated access to transacting assets. The purpose ... -
Information and sigma-algebras
2013-10In this work, we clarify the relationship between the information that an agent receives from a signal, from an experiment or from his own ability to determine the true state of nature that occurs and the information that ... -
Information and σ-algebras
2013In this work, we clarify the relationship between the information that an agent receives from a signal, from an experiment or from his own ability to determine the true state of nature that occurs and the information that ... -
A note on auctions with compulsory partnership
2016-12-01We study a symmetric, profit share, common value auction with a twist: One (fixed) Bidder, if not winning the auction, has to enter a partnership with the winner, sharing both expenses and revenue at rate (say) 0 < λ < 1. ... -
A note on the continuity of the optimal auction
2015In the independent private values auction model I study the continuity properties of the optimal auction revenue as a function of the valuations or types distribution. I show that the optimal revenue is lowersemicontinuous ... -
Private provision of discrete public goods with incomplete information
2001-07We analyze the private provision of discrete public good games with incomplete information and continuous contributions. To use the terminology of [Admati and Perry, Review of Economic Studies 58 (1991) 259], we consider ... -
Run theorems for low returns and large banks
2014-10In this paper, we revisit the issue of bank fragility in the Diamond and Dybvig (J Polit Econ 91:401-419, 1983) model with sequential service and finite traders. We provide a precise condition under which banks are susceptible ... -
Shortcomings of the Brazilian pre-salt auction design
2016-12-01The Brazilian government instituted a new regulatory framework for auctioning pre-salt oil reserves to replace the previous concession regime with a profitshare bidding auction. Motivated by the new rules, we present a ... -
Strictly monotonic preferences on continuum of goods commodity spaces
2010-09-20We consider a set K of differentiated commodities. A preference relation on the set of consumption plans is strictly monotonic whenever to consume more of at least one commodity is more preferred. It is an easy task to ... -
Uniform payoff security and Nash equilibrium in compact games
2007We introduce a condition, uniform payoff security, for games with compact Hausdorff strategy spaces and payoffs bounded and measurable in players' strategies. We show that if any such compact game G is uniformly payoff ...
