This paper develops a model of inflation inertia based on optimizing forward looking staggered price setting in a small open economy. Unlike in current models of sticky prices, transitions to a lower steady state inflation rate take time even if they are fully credible, and they are associated...

The paper assesses, using seven structural models used heavily by policymaking institutions, the effectiveness of temporary fiscal stimulus. Models can, more easily than empirical studies, account for differences between fiscal instruments, for differences between structural characteristics of...

This working paper presents a comprehensive overview of the theoretical structure of the Global Integrated Monetary and Fiscal Model (GIMF), a multi-region dynamic general equilibrium model that is used by the IMF for a variety of tasks including policy analysis, risk analysis, and surveillance

This paper uses two of the IMF's DSGE models to simulate the benefits of international fiscal and macroprudential policy coordination. The key argument is that these two policies are similar in that, unlike monetary policy, they have long-run effects on the level of GDP that need to be traded...

The paper studies how high household leverage and crises can arise as a result of changes in the income distribution. Empirically, the periods 1920-1929 and 1983-2008 both exhibited a large increase in the income share of high-income households, a large increase in debtleverage of the remainder,...

This paper asks whether an aggressive monetary policy response to inflation is feasible in countries that suffer from fiscal dominance, as long as monetary policy also responds to fiscal variables. We find that if nominal interest rates are allowed to respond to government debt, even aggressive...

This paper develops a theory of inflation inertia based on forward looking staggered price setting in the nontradable goods sector of a small open economy. Unlike current theories of sticky prices, transitions to a lower steady state inflation rate take time even if they are fully credible, and...

This paper develops a dynamic stochastic general equilibrium monetary portfolio choice model that accomplishes two objectives. First, it provides a theory of currency risk premia based on a weak and plausible form of fiscal nonneutrality. Domestic and foreign bonds become imperfect substitutes,...

This paper provides a monetary model with nominal rigidities that differs from the conventional New Keynesian model with firms setting pricing policies instead of price levels. In response to permanent or highly persistent monetary policy shocks this model generates the empirically observed slow...

The literature on optimal fiscal policy finds that highly volatile real returns on government debt, for example through surprise inflation, have very low costs. However, policymakers are almost always very apprehensive of this option. The paper discusses evidence concerning features of...
