We calculate learning rates when agents are informed through both public and private observation of other agents' actions. We provide an explicit solution for the evolution of the distribution of posterior beliefs. When the private learning channel is present, we show that convergence of the...

In these excerpts from "The Squam Lake Report", fifteen distinguished economists analyze where the global financial system failed, and how such failures might be prevented (or at least their damage better contained) in the future. Although there were many contributing factors to the...

I describe asset price dynamics caused by the slow movement of investment capital to trading opportunities. The pattern of price responses to supply or demand shocks typically involves a sharp reaction to the shock and a subsequent and more extended reversal. The amplitude of the immediate price...

capital is imbalanced between the two markets.

Recent scandals over the manipulation of LIBOR and foreign exchange benchmarks have spurred policy discussions of the appropriate design of financial benchmarks. We solve a version of the problem faced by a financial benchmark administrator. Acting as a mechanism designer, the benchmark...

We analyze the role of benchmarks in over-the-counter markets subject to search frictions. The publication of a benchmark can, under conditions, raise total social surplus by (i) increasing the volume of beneficial trade, (ii) reducing total search costs, and (iii) facilitating more efficient...

We outline key steps necessary to reform the London Interbank Offered Rate (LIBOR) so as to improve its robustness to manipulation. We first discuss the role of financial benchmarks such as LIBOR in promoting over-the-counter market efficiency by improving transparency. We then describe how to...

A central counterparty (CCP) is a financial market utility that lowers counterparty default risk on specified financial contracts by acting as a buyer to every seller, and as a seller to every buyer. When at risk of failure, a CCP could be forced into a normal insolvency process such as...

We study equilibria of dynamic over-the-counter markets in which agents are distinguished by their preferences and information. Over time, agents are privately informed by bids and offers. Investors differ with respect to information quality, including initial information precision, and also in...
