Since the advent of heteroskedasticity-robust standard errors, several papers have proposed adjustments to the original … samples. We propose a class of alternative heteroskedasticity-robust tests of linear hypotheses based on an Edgeworth …, moderate, and severe levels of heteroskedasticity. …

Pesaran and Yamagata (Pesaran, M.H., Yamagata, T., Testing slope homogeneity in large panels, Journal of Econometrics 142, 50–93, 2008) propose a test for slope homogeneity in large panels, which has become very popular in the literature. However, the test cannot deal with the practically...

We propose an IV panel unit root test robust to nonstationary error volatility. Its finite-sample performance is convincing even for many units and strong cross-correlation. An application to GDP prices illustrates the inferential impact of nonstationary volatility.

This paper proposes a test for path dependence in discrete panel data based on a characterization of stochastic processes that are mixtures of Markov chains. This test is applied to European Community Household Panel data on employment histories. The data allow to reject the null of no path...

In this paper, several tests are suggested for the existence of individual and time effects in panel data models with interactive effects. Their asymptotic properties are obtained under some mild conditions. Monte Carlo simulation is carried out for illustration.

This paper develops a simple test à la Pesaran (2007) for the null hypothesis of stationarity in heterogeneous panel data with cross-sectional dependence in the form of a common factor in the disturbance. We also allow for serial correlation.

Standard tests are generally not applicable in panel data models with selection. The paper shows how the Hausman specification test and the Sargan–Hansen test for overidentifying restrictions can be generalized to panel data models with unobserved heterogeneity and sample selection.

In this paper, we test the Prebish–Singer (PS) hypothesis, which states that real commodity prices decline in the long run, using two recent powerful panel data stationarity tests accounting for cross-sectional dependence and a structural break. We find that the hypothesis cannot be rejected...

This paper investigates the quasi-maximum likelihood (QML) estimation of spatial panel data models where spatial weights matrices can be time varying. We show that QML estimate is consistent and asymptotically normal. We also derive the asymptotic distribution of average impact coefficients...

We obtain an LM test for the random effects probit model. In the natural parameterization of the model the necessary derivatives are identically zero under the null hypothesis. After a reparameterization, the feasible LM test is based on generalized residuals.
