Abstract This paper generalizes the univariate unit root test proposed by Sollis (2009) by adding correlated covariates for a power boost. The asymptotic distribution of the proposed test is derived, and the asymptotic critical values are tabulated. Simulation experiments are conducted to...

Mixed results for unemployment dynamics are reported in many studies using linear or non-linear unit root tests. A possible explanation is that the literature focuses on the average behavior of unemployment and assumes that the speed of adjustment towards its long-run equilibrium is constant,...

In this paper, we intend to develop a new unit root testing procedure. The novelty of this methodology includes (1) accommodating possible trend breaks of unknown number, unknown dates, and unknown form by employing the Fourier form without directly estimating such breaks; (2) considering...

This paper applies the regression quantile approach developed by Koenker and Xiao (2004) to investigate the dynamic behavior of inflation in 12 OECD countries. By analyzing the behavior in a wide range of quantiles, this method allows us to quantify the influence of various sizes of shocks that...

Event forecasts, often generated from estimated econometric models, comprise a binary time series. In empirical finance, the market timing test proposed by Henricksson and Merton (1981) is probably the most popular method to assess the accuracy of these forecasts. Unfortunately, event forecasts...

This paper investigates whether distributional effect arising from the impact of monetary policy on bank credits will be different when monetary policy is asymmetric. Methodologically, we use a set of high frequency panel data for Taiwan commercial banks and adopt Arellano and Bond's (1991)...
