Attainment of rational expectations equilibria in asset markets calls for the price system to disseminate agents' private information to others. Markets populated by human agents are known to be capable of converging to rational expectations equilibria. This paper reports comparable market...

We use the theory of abstract convexity to study adverse-selection principal-agent problems and two-sided matching problems, departing from much of the literature by not requiring quasilinear utility. We formulate and characterize a basic underlying implementation duality. We show how this...

Abstract We develop a tractable model of competitive insurance markets with a continuum of types and exogenous restrictions on the set of allowed contracts. Our model nests, as special cases, the market for lemons of Akerlof (1970) and the unrestricted contracts setting of Rothschild and...

Over 20 years, M&A contracts have more than doubled in size – from 35 to 88 single-spaced pages in this paper's font. They have also grown significantly in linguistic complexity – from post-graduate “grade 20” to post-doctoral “grade 30”. A substantial portion (lower bound ~20%) of...

In the statistical physics, each microstate must be permitted by the Newton equations (or Schrodinger equations). Likewise, each microstate of economic system must be allowed by the general equilibrium theory. Our study shows that the competitive economy, over a long time scale, would produce a...

We model a simple dynamic process in which boundedly rational agents learn through their interactions with others. Of interest is to study the process of contagion where by one action 'spreads throughout the population' and becomes conventional. We vary the network of player interaction between...

In this paper we propose a simple binary mean field game, where N agents may decide whether to trade or not a share of a risky asset in a liquid market. The asset's returns are endogenously determined taking into account demand and transaction costs. Agents' utility depends on the aggregate...

This paper investigates a dynamic agency problem that includes the AI-style agent and principal. We develop a quantitative bionic approach to dynamic contracting based on calibrating the incentive properties of a workhorse contracts model in which self-awareness and memory are endowed. We...

Optimal rank-order tournaments have traditionally been studied using a first-order approach. The present analysis relies instead on the construction of an "upper envelope" over all incentive compatibility conditions. lt turns out that the first-order approach is not innocuous. For example, in...
