This paper considers a first-order autoregressive model with conditionally heteroskedastic innovations. The asymptotic distributions of least squares (LS), infeasible generalized least squares (GLS), and feasible GLS estimators and t statistics are determined. The GLS procedures allow for...

Overall competitiveness of the Dutch economy seems adequate, but domestically produced exports have lost market share recently. Over the past three decades, globalization has greatly influenced economies as countries have become more integrated. Empirical studies on business cycles...

This Selected Issues Paper on Iran reviews that monetary factors are the main determinants of inflation in the country. Government spending out of oil revenues leads to large liquidity injections that the central bank accommodates owing to its efforts to prevent a significant nominal...

Necessary and sufficient conditions for the existence of order statistics moments of α-stable random variables are introduced. Using the obtained results, all parameters of α-stable distribution are estimated.

Asymptotic properties of the harmonic moment tail index Estimator are derived for distributions with regularly varying tails. The estimator shows good robustness properties and stands out for its simplicity. A tuning parameter allows for regulating the trade-off between robustness and...

The occurrence of instantaneous or early failures is a common phenomenon observed in life testing experiments. Such failures are called inliers. In this article, an attempt has been made to model inliers using Rayleigh distribution. We propose the estimation procedures and tests of hypothesis of...

In this paper we provide a formal yet simple and straightforward proof of the asymptotic χ<Superscript>2</Superscript> distribution for Cochran test statistic. Then, we show that the general form of this type of test statistics is invariant for the choice of weights. This fact is important since in practice many such...</superscript>

The empirical saddlepoint distribution provides an approximation to the sampling distributions for the GMM parameter estimates and the statistics that test the overidentifying restrictions. The empirical saddlepoint distribution permits asymmetry, non-normal tails, and multiple modes. If...
