Fiscal Forward Guidance: A Case for Selective Transparency
Should the fiscal authority use forward guidance to reduce future policy uncertainty perceived by private agents? Using dynamic stochastic general equilibrium models, we examine the welfare effects of announcing future fiscal policy shocks. Analytical as well as numerical experiments show that selective transparency is desirable?announcing future fiscal policy shocks that are distortionary can be detrimental to ex ante social welfare, whereas announcing nondistortionary shocks generally improves welfare. Sizable welfare gains are found with constructive ambiguity regarding the timing of a ...

DECLINING TRENDS IN THE REAL INTEREST RATE AND INFLATION: THE ROLE OF AGING
This paper explores a causal link between aging of the labor force and declining trends in the real interest rate and inflation in Japan. We develop a New Keynesian search/matching model that features heterogeneities in age and firm-specific skills. Using the model, we examine the long-run implications of the sharp drop in labor force entry in the 1970s. We show that the changes in the demographic structure induce significant low-frequency movements in per-capita consumption growth and the real interest rate. They also lead to similar movements in the inflation rate when the monetary policy ...

Generational War on Inflation: Optimal Inflation Rates for the Young and the Old
How does a grayer society affect the political decision-making regarding inflation rates? Is deflation preferred as a society ages? In order to answer these questions, we compute the optimal inflation rates for the young and the old respectively, and explore how they change with demographic factors, by using a New Keynesian model with overlapping generations. According to our simulation results, there indeed exists a tension between the young and the old on the optimal inflation rates, with the optimal inflation rates differing between generations. The rates can be significantly different ...

Real exchange rate dynamics revisited: a case with financial market imperfections
In this paper, we investigate the relationship between real exchange rate dynamics and financial market imperfections. For this purpose, we first construct a New Open Economy Macroeconomics (NOEM) model that incorporates staggered loan contracts as a simple form of the financial market imperfections. Our model with such a financial market friction replicates persistent, volatile, and realistic hump-shaped responses of real exchange rates, which have been thought very difficult to materialize in standard NOEM models. Remarkably, these realistic responses can materialize even with both supply ...

Export shocks and the zero bound trap
When a small open economy experiences a sufficiently large negative export shock, it is vulnerable to falling into a zero bound trap. In addition, such a shock can have very large impact on the economy compared to the case when the zero bound is not a binding constraint. This could be one possible explanation as to why a country like Japan experienced much larger drop in output than the United States during the recent financial crisis.

Aging and the Real Interest Rate in Japan: A Labor Market Channel
This paper explores a causal link between aging of the labor force and declining trends in the real interest rate in Japan. We develop a search/matching model that features heterogeneous workers with respect to their ages and firm-specific skills. Using the model, we examine the long-run implications of the sharp drop in labor force entry in the 1970s. We show that the changes in the demographic structure induce significant low-frequency movements in per capita consumption growth and the real interest rate. The model suggests that aging of the labor force accounts for 40 percent or more of ...

The Optimal Degree of Monetary-Discretion in a New Keynesian Model with Private Information
This paper considers the optimal degree of monetary-discretion when the central bank conducts policy based on its private information about the state of the economy and is unable to commit. Society seeks to maximize social welfare by imposing restrictions on the central bank's actions over time, and the central bank takes these restrictions and the New Keynesian Phillips curve as constraints. By solving a dynamic mechanism design problem we find that it is optimal to grant ?constrained discretion? to the central bank by imposing both upper and lower bounds on permissible inflation, and that ...

The fiscal multiplier and spillover in a global liquidity trap
We consider the fiscal multiplier and spillover in an environment in which two countries are caught simultaneously in a liquidity trap. Using an optimizing two-country sticky price model, we show that the fiscal multiplier and spillover are contrary to those predicted in textbook economics. For the country with government expenditure, the fiscal multiplier exceeds one, the currency depreciates, and the terms of trade worsen. The fiscal spillover is negative if the intertemporal elasticity of substitution in consumption is less than one and positive if the parameter is greater than one. ...

Foreign Exchange Reserves as a Tool for Capital Account Management
Many recent theoretical papers have argued that countries can insulate themselves from volatile world capital flows by using a variable tax on foreign capital as an instrument of monetary policy. But at the same time many empirical papers have argued that only rarely do we observe these cyclical capital taxes used in practice. In this paper we construct a small open economy model where the central bank can engage in sterilized foreign exchange intervention. When private agents can freely buy and sell foreign bonds, sterilized foreign exchange intervention has no effect. But we analytically ...
