This paper considers two-sided tests for the parameter of an endogenous variable in an instrumental variable (IV) model with heteroskedastic and autocorrelated errors. We develop the finite-sample theory of weighted-average power (WAP) tests with normal errors and a known long-run variance. We...

Researchers often rely on the t-statistic to make inference on parameters in statistical models. It is common practice to obtain critical values by simulation techniques. This paper proposes a novel numerical method to obtain an approximately similar test. This test rejects the null hypothesis...

In this paper we investigate bootstrap-based methods for bias-correcting the first-stage parameter estimates used in … some recently developed bootstrap implementations of the co-integration rank tests of Johansen (1996). In order to do so we … the corresponding parameter esti- mates taken across a large number of auxiliary bootstrap replications. A number of …

In this paper, we propose a model-free bootstrap method for the empirical process under absolute regularity. More … precisely, consistency of an adapted version of the so-called dependent wild bootstrap, that was introduced by Shao (2010) and … simulation study shows that our method is competitive to standard block bootstrap methods in finite samples. …

The concept of the autoregressive (AR) sieve bootstrap is investigated for the case of spatial processes in Z2. This … procedure fits AR models of increasing order to the given data and, via resampling of the residuals, generates bootstrap … criterion which allows to decide whether the AR sieve bootstrap asymptotically works for a specific statistic of interest or not …

We present a non-parametric method to estimate the discount curve from market quotes based on the Moore-Penrose pseudoinverse. The discount curve reproduces the market quotes perfectly, has maximal smoothness, and is given in closed-form. The method is easy to implement and requires only basic...

This paper establishes the ability of a Real Business Cycle model to account for real exchange rate behaviour, using UK data. We show that a productivity simulation is capable of explaining initial real appreciation with subsequent depreciation to a lower steady state. The model is tested by the...

Using Monte Carlo experiments, we examine the performance of indirect inference tests of DSGE models in small samples, using various models in widespread use. We compare these with tests based on direct inference (using the Likelihood Ratio). We find that both tests have power so that a...
