I argue that fiscal policy uncertainty can have large and adverse effects when the monetary authority is constrained by the zero lower bound on nominal interest rates. Using a new-Keynesian model with endogenous capital accumulation, I show that uncertainty about short-run and longrun fiscal policy can cause large falls in consumption, investment, and output when the zero lower bound binds, but...

In the standard New Keynesian model, monetary policy is often described by an interest rate rule (e.g. a Taylor rule) that moves the interest rate in response to deviations of inflation and some measure of economic activity from target. Nominal interest rates are bound from below by 0 – since money is storable, one would never accept a negative nominal return. How does the behavior of the NK mo...

We introduce liquidity frictions into an otherwise standard DSGE model with nominal and real rigidities, explicitly incorporating the zero bound on the short-term nominal interest rate. Within this framework, we ask: Can a shock to the liquidity of private paper lead to a collapse in short-term nominal interest rates and a recession like the one associated with the 2008 U.S. financial crisis? O...

The analyses by the first ranked economists show that the economical growth of the countries that import oil or non-oil developing countries (NODCs) depends on the economical growth of the industrial countries. “Goldstein” & “Khan” by means of a long & complete verification show the dependence of the economical growth and “Callier” also claims this fact that the economical growth of the countri...

A similar negative correlation between inflation and stock prices prompted Modigliani and Cohn to conjecture that investors are prone to money illusion: they confuse nominal and real interest rates. When that is the case investors mistakenly discount real future cash flows with the nominal interest rate (or alternatively ignore the fact that cash flows tend to grow in nominal terms as inflation...

Wallace attempts to analyse central bank interest rate control in a cashless, ArrowDebreu economy. The model incorporates only the unit of account function of money and exhibits a version of the classical dichotomy in which arbitrary accounting prices are independent of the equilibrium real relative price vector. A model with these properties is incapable of providing a theory of the price leve...

Changes in nominal interest rates must be due to either movements in real interest rates, expected inflation, or the inflation risk premium. We develop a term structure model with regime switches, time-varying prices of risk, and inflation to identify these components of the nominal yield curve. We find that the unconditional real rate curve in the U.S. is fairly flat around 1.3%. In one real r...

M any central banks have long used a short-term nominal interest rate as the main instrument through which monetary policy actions are implemented. Some monetary authorities have even viewed their main job as managing nominal interest rates, by using an interest rate rule for monetary policy. It is therefore important to understand the consequences of such monetary policies for the behavior of ...
