We evaluate the Smets-Wouters model of the US dynamically using indirect inference with a VAR representation of the main US data series. We find that the New Keynesian SW model is badly rejected by the data's dynamic properties and in particular cannot match the variability of the data. An alternative (New Classical) version of the model with flexible wages and prices and a one-period information lag fares no better. A 'weighted' model (mostly NC but part NK) is able to match the data variability, though it too is rejected overall. Allowing for structural breaks in monetary regime we find a model from 1984 onwards fits fairly well dynamically; this has a high NK weight, suggesting much greater nominal stickiness during the 'great moderation'.

Terms of use: Documents in AbstractWith Monte Carlo experiments on models in widespread use we examine the performance of indirect inference (II) tests of DSGE models in small samples. We compare these tests with ones based on direct inference (using the Likelihood Ratio, LR). We …nd that both tests have power so that a substantially false model will tend to be rejected by both; but that the power of the II test is substantially greater, both because the LR is applied after reestimation of the model error processes and because the II test uses the false model's own restricted distribution for the auxiliary model's coe¢ cients. This greater power allows users to focus this test more narrowly on features of interest, trading o¤ power against tractability.JEL Classi…cation: C12, C32, C52, E1

Instead it now seems more promising to assume that financial assets, and specifically bonds and credit, are imperfect substitutes and that money substitutes with a wide variety of financial and real assets in rather different ways; in such a world we can find a role * Corresponding Author: LeVP@cardiff.ac.uk 1 for Quantitative Easing (QE) -Open Market Operations -that has now become a major instrument of monetary policy. This world harks back to that of Friedman's Quantity Theory restatement (Friedman, 1956) and Brunner and Meltzer's papers on the banking system (e.g. Brunner and Meltzer, 1963) as a transmission mechanism for money. Terms of use: Documents in EconStor mayIn this paper our aim is to construct a DSGE model in which this imperfect substitution occurs between financial assets and in which therefore money has a role beyond merely setting the interest rate on shortterm government bonds, 'bank rate' for short. To do this we borrow from available models of the economy, banking and collateral to create out of them what could be called a 'neo-monetarist' model. Another element we inject is the possibility of hitting the zero bound on the bank rate; we do this quite simply by suspending the Taylor Rule when bank rate solves for this level or below and replacing it with this exogenous lower bound; this does not undermine inflation determinacy because this situation cannot continue indefinitely since the shocks to interest rates must die out in time. We test this model against the key features of US macroeconomic data and compare its performance with other models that do not have these new elements;we find that our augmented model gets somewhat closer to the data's behaviour.The model has clear welfare and policy implications. In the economy there are two main interest rate...

The downturn in the world economy following the global banking crisis has left the Chinese economy relatively unscathed. This paper develops a model of the Chinese economy using a DSGE framework with a banking sector to shed light on this episode. It differs from other applications in the use of indirect inference procedure to test the fitted model. The model finds that the main shocks hitting China in the crisis were international and that domestic banking shocks were unimportant. However, directed bank lending and direct government spending was used to supplement monetary policy to aggressively offset shocks to demand. The model finds that government expenditure feedback reduces the frequency of a business cycle crisis but that any feedback effect on investment creates excess capacity and instability in output.

Terms of use: Documents in EconStor may March 2013 AbstractWe propose a numerical method, based on indirect inference, for checking the identification of a DSGE model. Monte Carlo samples are generated from the model's true structural parameters and a VAR approximation to the reduced form estimated for each sample. We then search for a different set of structural parameters that could potentially also generate these VAR parameters. If we can find such a set, the model is not identified.
