This paper addresses the positive and normative implications of indexing risky debt to observable aggregate conditions. These issues are pursued within the context of the celebrated financial accelerator model of Bernanke, Gertler and Gilchrist (1999). The principal conclusions are that the...

This paper derives the privately optimal lending contract in the celebrated financial accelerator model of Bernanke, Gertler and Gilchrist (1999). The privately optimal contract includes indexation to the aggregate return on capital and household consumption. Although privately optimal, this...

This paper asks the following two questions: First, can a model with nominal rigidities in wage and price setting account for the average welfare costs of business cycle fluctuations identified in Gali, Gertler, and Lopez- Salido (2003)? Second, what is the role of contracting schemes for the...

A popular identifying assumption in structural VAR studies is that the monetary policy shock does not affect macroeconomic variables contemporaneously. We examine the consequences of using this identification strategy when the data-generating process is a basic Dynamic New Keynesian (DNK) model...

We show that interest rate rules that feed back on the growth rates of target variables (such as output or asset prices) may induce recessions in the presence of a zero lower bound, through purely self-fulfilling dynamics. This pathology is illustrated in a small New Keynesian model with...

A method to evaluate cyclical models not requiring knowledge of the DGP and the exact specification of the aggregate decision rules is proposed. We derive robust restrictions in a class of models; use some to identify structural shocks in the data and others to evaluate the class or contrast...
