Bank capital standards for market risk: a welfare analysis
We develop a model of commodity money and use it to analyze the following two questions motivated by issues in monetary history: What are the conditions under which Gresham's Law holds? And, what are the mechanics of a debasement (lowering the metallic content of coins)? The model contains light and heavy coins, imperfect information, and prices determined via bilateral bargaining. There are equilibria with neither, both, or only one type of coin in circulation. When both circulate, coins may trade by weight or by tale. We discuss the extent to which Gresham's Law holds in the various cases. ...

The crisis of 1998 and the role of the central bank
Following the Russian default and devaluation in August 1998, financial markets were characterized by a withdrawal of liquidity, a flight to the safest assets, increased concerns about credit quality, and large declines in asset values. However, the crisis ended following a rather modest interest rate cut by the Federal Reserve. Why did the central bank's action have this effect? This article argues that the crisis was an episode of potential coordination failure, triggered by, but distinct from, the events in Russia. The Federal Reserve's action signaled a policy change that serve to ...

Economic determinants of the nominal treasury yield curve
We study the effect of different types of macroeconomic impulses on the nominal yield curve. We employ two distinct approaches to identifying economic shocks in VARs. Our first approach uses a structural VAR due to Gal (1992). Our second strategy identifies fundamental impulses from alternative empirical measures of economic shocks proposed in the literature. We find that most of the long-run variability of interest rates of all maturities is driven by macroeconomic impulses. Shocks to preferences for current consumption consistently induce large, persistent, and statistically significant ...

Consumption-based modeling of long-horizon returns
Numerous studies have documented the failure of consumption-based pricing models to explain observed patterns in stock and bond returns. This failure has sometimes been attributed to frictions, transaction costs or durability. If such frictions are important, they should primarily affect the higher frequency components of asset returns. The long-swings, or lower-frequency comovements should be less affected. Consequently if transaction costs are important, tests of the consumption based asset pricing model which concentrate on lower-frequency components may be more successful.

\"Peso problem\" explanations for term structure anomalies
We examine the empirical evidence on the expectation hypothesis of the term structure of interest rates in the United States, the United Kingdom, and Germany using the Campbell-Shiller (1991) regressions and a vector-autoregressive methodology. We argue that anomalies in the U.S. term structure, documented by Campbell and Shiller (1991), may be due to a generalized peso problem in which a high-interest rate regime occurred less frequently in the sample of U.S. data than was rationally anticipated. We formalize this idea as a regime-switching model of short-term interest rates estimated with ...

Thoughts on financial derivatives, systematic risk, and central banking: a review of some recent developments
This paper critically reviews the literature examining the role of central banks in addressing systemic risk. We focus on how the growth in derivatives markets might affect that role. Analysis of systemic risk policy is hampered by the lack of a consensus theory of systemic risk. We propose a set of criteria that theories of systemic risk should satisfy, and we critically discuss a number of theories proposed in the literature. We argue that concerns about systemic effects of derivatives appear somewhat overstated. In particular, derivative markets do not appear unduly prone to systemic ...

Bank capital regulation with and without state-contingent penalties
A moral hazard model with exogenous bank franchise value is used to analyze bank capital regulation. Banks choose their capital structure as well as the riskiness and mean of their portfolio. The portfolio mean is determined by the level of costly screening. Screening and portfolio risk are private information, so there are two dimensions to the moral hazard problem. Deposit insurance gives banks an incentive to hold less capital, and to choose a higher-risk, lower-mean portfolio. To mitigate these incentives, capital requirements with and without ex post fines are studied. We find an ...

The role of time-critical liquidity in financial markets
This article examines the growing dependence of global financial markets on time-critical liquidity in managing settlement risk and its implications for financial regulation.
