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...

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 tractable overlapping generations model that is useful for analyzing both the short and long run impact of fiscal policy and social security. It modifies the Blanchard (1985)/Weil (1987) framework to allow for life/cycle behavior. This is accomplished by introducing random...

In the spring of 2013 the Bank of Japan introduced a state-of-the-art monetary policy which included among other things inflation targeting and aggressive use of forward guidance. In contrast to the predictions of conventional macroeconomic theory, these policies have had only very limited...

This paper characterizes a multi-period production economy in which borrowers and lenders enter long-term financial contracts. A key feature is that aggregate production and borrowers' capacity to absorb debt -- their "financial capacity" - are jointly determined endogenous variables, in the...

Over the past decade, a number of researchers have extended conventional models of business fixed investment to incorporate a role for financial constraints' in determining investment. This paper reviews developments and challenges in this empirical research, and uses advances in models of...

This paper argues that the terms `money view' and `credit view' are not always well defined in theoretical and empirical debates over the transmission mechanism of monetary policy. Recent models of information and incentive problems in financial markets suggest the usefulness of decomposing the...

This paper focuses on precautionary saving against uncertain longevity and on the annuity insurance aspects of social security within the life-cycle framework. The principal findings are three. First, the evolution of social security is reviewed in response to missing markets for providing...

Attempts to measure the impacts of pensions on household saving have occupied much of the literature in empirical public finance over the past decade. The emphasis here is on the annuity insurance aspects of social security and pensions. A simple life-cycle model is put forth to show that even...
