February 1998 <p> In smooth exchange economies with a continuum of agents, any Walrasian mechanism is Pareto efficient, individually rational, anonymous, and strategy-proof.  Barberà and Jackson's (1995) results imply that no such efficient mechanism is the limit of resource-balanced,...</p>

Von Neumann’s standard paradigm of a game in extensive form and Kolmogorov’s standard model of a stochastic process both rely on constructing a fixed state space large enough to include all possible future eventualities. This allows a typical singleperson decision problem to be represented...

An extensive literature in economics uses a continuum of random variables to model individual random shocks imposed on a large population. Let H denote the Hilbert space of square-integrable random variables. A key concern is to characterize the family of all H-valued functions that satisfy the...

A mass-economy is one with many, many agents where each agent is negligible and each trading group is also negligible with respect to the mass-economy. Feasible allocations are those which are virtually attainable by trades only among members of coalitions contained in feasible...

May 1997 (Revised May 1998) <p> By definition, multilaterally strategy-proof mechanisms are immune to manipulation not only by individuals misrepresenting their preferences, but also by finite coalitions exchanging tradeable goods on the side. Continuum economies are defined in which both agents'...</p>

July 2000 <p> Marshallian consumer surplus (MCS) is generally an inaccurate measure of welfare change because it neglects income effects. Suppose these effects overturn the usual demand response to a price change. Then, the deadweight loss from a distortionary tax or subsidy has the wrong sign,...</p>

October 1997 (Now published: Scandinavian Journal of Economics, 100 (1998), 11--32.) <p> There are two distinct "Scandinavian consensus" approaches to public good supply, both based on agents' willingness to pay.  A Wicksell--Foley public competitive equilibrium arises from a negative consensus in...</p>
