We present the results of a simulation study into the properties of 12 different estimators of the Hurst parameter, H, or the fractional integration parameter, d, in long memory time series. We compare and contrast their performance on simulated Fractional Gaussian Noises and fractionally...

A common practice in applied econometrics consists of replacing a suspected endogenous variable with its lagged values. This note demonstrates that lagging an endogen¬ous variable does not enable one to escape simultaneity bias. The associated estimates are still inconsistent, and hypothesis...

A common practice in applied economics research consists of replacing a suspected simultaneously-determined explanatory variable with its lagged value. This note demonstrates that this practice does not enable one to avoid simultaneity bias. The associated estimates are still inconsistent, and...

This paper replicates and analyses a study by Hoover and Pecorino (2005) on federal spending in US states. H&P followed on path-breaking research by Atlas et al. (1995) in which evidence was claimed in favour of the “small state effect;” namely, that since every state is represented by two...

This paper replicates and analyses a study by Hoover and Pecorino on Federal spending in US states (Hoover and Pecorino, 2005; henceforth H&P). H&P followed on path-breaking research by Atlas et al. (1995) in which evidence was claimed in favour of the “small state effect;” namely, that since...

In this paper, we develop a modified maximum likelihood (MML) estimator for the multiple linear regression model with underlying student t distribution. We obtain the closed form of the estimators, derive the asymptotic properties, and demonstrate that the MML estimator is more appropriate for...

This study replicates the empirical findings of Toya and Skidmore (2007), hereinaf¬ter “TS”, and performs a variety of robustness checks. We are able to exactly replicate the find¬ings reported by TS. Our robustness checks consist of two parts. Firstly, we update TS’s orig¬in¬al data...

Despite the high volatilities recorded for electricity prices, there seems to be little demand for options on electricity. One reason for the disinterest in electricity options could arise from uncertainty about how to price these options. This study uses recent econometric advances to...

This paper examines the effects of structural change, long-term TFP trend and marginal return to capital on China’s economic growth, comparing such effects with those in the other East Asian economies. Our empirical results show that China’s TFP converges to a higher level, and that the...

This paper demonstrates that unit root tests can suffer from inflated Type I error rates when data are cointegrated. Results from Monte Carlo simulations show that three commonly used unit root tests – the ADF, Phillips-Perron, and DF-GLS tests – frequently overreject the true null of a unit...
