Optimal Monetary Policy under Negative Interest Rate
In responding to the extremely weak global economy after the financial crisis in 2008, many industrial nations have been considering or have already implemented negative nominal interest rate policy. This situation raises two important questions for monetary theories: (i) Given the widely held doctrine of the zero lower bound on nominal interest rate, how is a negative interest rate (NIR) policy possible? (ii) Will NIR be effective in stimulating aggregate demand? (iii) Are there any new theoretical issues emerging under NIR policies? This article builds a model to show that (i) money ...
Long and Plosser Meet Bewley and Lucas
We develop a N-sector business cycle network model a la Long and Plosser (1983), featuring heterogenous money demand a la Bewley (1980) and Lucas (1980). Despite incomplete markets and a well-defined distribution of real money balances across heterogeneous households, the enriched N-sector network model remains analytically tractable with closed-form solutions up to the aggregate level. Relying on the tractability, we establish several important results: (i) The economy's input-output network linkages become endogenously time-varying over the business cycle?thanks to the influence of the ...
Liquidity Traps and Monetary Policy: Managing a Credit Crunch
We study a model with heterogeneous producers that face collateral and cash in advance constraints. These two frictions give rise to a non-trivial financial market in a monetary economy. A tightening of the collateral constraint results in a credit-crunch generated recession. The model can suitable be used to study the effects on the main macroeconomic variables - and on welfare of each individual - of alternative monetary - and fiscal - policies following the credit crunch. The model reproduces several features of the recent financial crisis, like the persistent negative real interest rates, ...
Discretion Rather than Rules: Equilibrium Uniqueness and Forward Guidance with Inconsistent Optimal Plans
New Keynesian economies with active interest rate rules gain equilibrium determinacy from the central bank?s incredible off-equilibrium-path promises (Cochrane, 2011). We suppose instead that the central bank sets interest rate paths and occasionally has the discretion to change them. Private agents taking future central bank actions and their own best responses to them as given reduces the scope for self-fulfilling prophecies. With empirically-reasonable frequencies of central-bank reoptimization, the monetary-policy game has a unique Markov-perfect equilibrium wherein forward guidance ...
Quantitative Easing in Joseph's Egypt with Keynesian Producers
This paper considers monetary and fiscal policy when tangible assets can be accumulated after shocks that increase desired savings, like Joseph's biblical prophecy of seven fat years followed by seven lean years. The model?s flexible-price allocation mimics Joseph?s saving to smooth consumption. With nominal rigidities, monetary policy that eliminates liquidity traps leaves the economy vulnerable to confidence recessions with low consumption and investment. Josephean Quantitative Easing, a fiscal policy that purchases either obligations collateralized by tangible assets or the assets ...
Open Mouth Operations
We examine the standard New Keynesian economy?s Ramsey problem written in terms of instrument settings instead of allocations. Its standard formulation makes two instruments available: the path of current and future interest rates, and an ?open mouth operation? which selects one of the many equilibria consistent with the chosen interest rates. Removing the open mouth operation by imposing a finite commitment horizon yields pathological policy advice that relies on the model's forward guidance puzzle.
What Does Anticipated Monetary Policy Do?
Forward rate guidance, which has been used with increasing regularity by monetary policymakers, relies on the manipulation of expectations of future short-term interest rates. We identify shocks to these expectations at short and long horizons since the early 1980s and examine their effects on contemporaneous macroeconomic outcomes. Our identification uses sign restrictions on survey forecasts incorporated in a structural VAR model to isolate expected deviations from the monetary policy rule. We find that expectations of future policy easing that materialize over the subsequent four quarters ...
Factor Specificity and Real Rigidities
We develop a multisector model in which capital and labor are free to move across firms within each sector, but cannot move across sectors. To isolate the role of sectoral specificity, we compare our model with otherwise identical multisector economies with either economy-wide factor markets (as in Chari et al. 2000) or firm-specific factor markets (as in Woodford 2005). Sectoral specificity induces within-sector strategic substitutability and across-sector strategic complementarity in price setting. Our model can produce either more or less monetary non-neutrality than those other two ...
The Transmission of Monetary Policy under the Microscope
We investigate the transmission of monetary policy to household consumption using detailed administrative data on the universe of households in Norway. Based on a novel series of identified monetary policy shocks, we estimate the dynamic responses of consumption, income, and saving along the liquid asset distribution of households. We find that low-liquidity but also high-liquidity households show strong responses, interest rate changes faced by borrowers and savers feed into consumption, and indirect effects of monetary policy outweigh direct effects, albeit with a delay. Overall, the ...
The Economic Effects of Trade Policy Uncertainty
We study the effects of unexpected changes in trade policy uncertainty (TPU) on the U.S. economy. We construct three measures of TPU based on newspaper coverage, firms' earnings conference calls, and aggregate data on tari rates. We document that increases in TPU reduce investment and activity using both firm-level and aggregate macroeconomic data. We interpret the empirical results through the lens of a two-country general equilibrium model with nominal rigidities and firms' export participation decisions. In the model as in the data, news and increased uncertainty about higher future ...
