This paper examines capital inflow dynamics for varying degrees of financial openness under a Taylor-type rule. The findings show that higher openness generates a more sensitive response in nontradable inflation, and that optimal monetary policy varies with the degree of openness.

We show that the CUSUM and LM tests for structural change in the volatility process enjoy monotonic power. The framework is general including many recently proposed non-stationary GARCH-type models. The result is in contrast to the well-known issue of non-monotonic power for the CUSUM-based...

This paper studies issues related to the estimation of a structural change in the persistence of a univariate time series. The break is such that the process has a unit root [i.e., is I(1)] in the pre-break regime but reverts to a stationary [i.e., I(0)] process in the post-break regime or vice...

We show that the (Baillie and Chung, 2001) minimum distance estimates of the GARCH (1,1) model induce spurious persistence in the volatility when there are structural changes in the mean of the process.

We propose to apply the group fused Lasso to estimate time series models with endogenous regressors and an unknown number of breaks. It can correctly determine the number of breaks and estimate the break dates asymptotically. Simulations and applications are given.

This paper studies the optimal interest rate rule in a DSGE model with housing market spillovers (Iacoviello and Neri, 2010). We find that the optimal rule responds to house price inflation even when the stabilization of house price is not among the objectives of the policymaker, and that the...

We show that to account for the cross-sectional divergence in debt-to-income ratios in US data a DSGE model must assume a tax reallocation across the top- and bottom-income quantile of the population, rather than differential productivity growth, and low cost of access to financial intermediation.

Using a stylized two-period model we compare portfolio solutions from two local solution approaches–the approach of Judd and Guu (2001) and the approach of Devereux and Sutherland (2010, 2011)–with the true nonlinear portfolio solution.

Using a heterogeneous firm model with firm entry and endogenous markups, I study how the financial constraints of exporting firms affect exchange rate pass-through behaviors. I find that the financial constraints increase the degree of exchange rate pass-through.

I analyze the perfect risk-sharing condition in the time–frequency domain using wavelets. Some countries engage more in risk-sharing at specific frequencies while others at all frequencies, but only for a short period of time. Increasing degree of risk-sharing over time is visible only for the...
