Is inflation targeting best-practice monetary policy?
Working Paper
Inflation targeting and nominal income growth targeting: when and why are they suboptimal?
We derive optimal monetary stabilization rules and compare them to simple rules under both full and partial information. The nominal interest rate is the instrument of monetary policy. Special attention is devoted to inflation targeting and nominal-income-growth targeting.> We use an optimizing-agent model of a closed economy which features monopolistic competition in both product and labor markets. A stabilization problem exists because there are one-period nominal contracts, either for wages alone or for both wages and prices, and three shocks that are unknown when contracts are signed. In ...

International coordination of macroeconomic policies: still alive in the new millennium?
In this paper we provide two building blocks for an analysis of international policy coordination: (1) a survey of models of policy coordination, and (2) an account of experience with policy coordination among the G-7 countries and within Europe since the breakdown of the Bretton Woods System. Using these building blocks, we investigate the correspondence between the models and experience and attempt to draw lessons for both the modelers and the practitioners. We find that the correspondence is close enough that the models help in analyzing several instances of actual policy coordination, but ...

Interpreting Shocks to the Relative Price of Investment with a Two-Sector Model
Consumption and investment comove over the business cycle in response to shocks that permanently move the price of investment. The interpretation of these shocks has relied on standard one-sector models or on models with two or more sectors that can be aggregated. However, the same interpretation continues to go through in models that cannot be aggregated into a standard one-sector model. Furthermore, such a two-sector model with distinct factor input shares across production sectors and commingling of sectoral outputs in the assembly of final consumption and investment goods, in line with ...

Investment-specific and multifactor productivity in multi-sector open economies: data and analysis
In the last half of the 1990s, labor productivity growth rose in the U.S. and fell almost everywhere in Europe. We document changes in both capital deepening and multifactor productivity (MFP) growth in both the information and communication technology (ICT) and non-ICT sectors. We view MFP growth in the ICT sector as investment-specific productivity (ISP) growth. We perform simulations suggested by the data using a two-country DGE model with traded and nontraded goods. For ISP, we consider level increases and persistent growth rate increases that are symmetric across countries and allow for ...

Can government gold be put to better use?: Qualitative and quantitative policies
Gold has both private uses (depletion uses and service uses) and government uses. It can be obtained from mines with high extraction costs (about $300 per ounce) or from above ground stocks with no extraction costs. Governments still store massive stocks of gold. Making government gold available for private uses through some combination of sales and loans raises welfare from private uses by removing two types of inefficiencies. For given private uses, there is a production inefficiency if costless government gold is withheld while costly gold is taken from mines. There are use inefficiencies ...
