Is corporate leverage excessive? Is the tax code distorting corporate capital structure decisions in a way that increases the possibility of an economic crisis owing to "financial instability"? <bR><bR>Answering these kinds of questions first requires some precision in terminology. In this paper, we...

Recent research in macroeconomics -- both theoretical and empirical -- has resurrected the idea that capital market imperfections may be significant factors in business volatility by making new progress in characterizing the mechanisms. This paper outlines a case for a financial aspect to...

We present a simple framework that incorporates a role for "interest rate spreads" in models of investment fluctuations. Formally, we develop a simple model of investment and financial contracting under asymmetric information that can he used to generate an Euler equation describing firms'...

This paper develops a simple model of corporate financial structure intended to formalize the macroeconomic concern over excessive leverage. In particular, we attempt to rationalize why firms designing an optimal capital structure would choose a level of debt that leaves them heavily exposed to...

The market for high yield (below investment-grade) corporate bonds developed in the middle 1980s. We show that, since this time, the high yield spread has had significant explanatory power for the business cycle. We interpret this finding as possibly symptomatic of financial factors at work in...

We describe some of the main features of the recent vintage macroeconomic models used for monetary policy evaluation. We point to some of the key differences with respect to the earlier generation of macro models, and highlight the insights for policy that these new frameworks have to offer. Our...

In this paper we present a simple, theory-based measure of the variations in aggregate economic efficiency associated with business fluctuations. We decompose this indicator, which we refer to as 'the gap', into two constituent parts: a price markup and a wage markup, and show that the latter...

We explore the implications of current account adjustment for monetary policy within a simple two-country DSGE model. Our framework nests Obstfeld and Rogoff's (2005) static model of exchange rate responsiveness to current account reversals. It extends this approach by endogenizing the dynamic...

This paper pinpoints sources of recent problems in U.S. commercial banking. The objective is to provide a context for evaluating policy options. There are three parts. The first documents how increased competition and financial innovation made banking less stable in the 1980s. The second part...

We develop a model in which innovations in an economy's growth potential are an important driving force of the business cycle. The framework shares the emphasis of the recent "new shock" literature on revisions of beliefs about the future as a source of fluctuations, but differs by tieing these...
