This paper develops a method for testing for the presence of a single structural break in dynamic panel data models with a multi-factor error structure. The test statistic is developed by combining a modified version of the GMM approach of Robertson and Sarafidis (2015) with the testing procedure of De Wachter and Tzavalis (2012). We focus on the case where N is large and T fixed. The asymptoti...

Regression and linear programming provide the basis for popular techniques for estimating technical efficiency. Regression-based approaches are typically parametric and can be both deterministic or stochastic where the later allows for measurement error. In contrast, linear programming models are nonparametric and allow multiple inputs and outputs. The purported disadvantage of the regression-b...

The EC (Estimation-Classiication) estimator, and its companion EC-algorithm, were introduced in El-Gamal and Grether (1995), and their properties further analyzed in El-Gamal and Grether (1996). The purpose of EC estimation is to uncover heterogeneity in panel data models in a manner which is more parsimonious and computationally less costly than some of the standard methods (e.g. xed eeects). ...

This paper considers the problem of comparing two processes with panel data. A nonparametric test is proposed for detecting a monotone change in the link between the two process distributions. The test statistic is of CUSUM type, based on the empirical distribution functions. The asymptotic distribution of the proposed statistic is derived and its finite sample property is examined by bootstrap...

Estimating and Testing a Quantile Regression Model with Interactive Effects This paper proposes a quantile regression estimator for a panel data model with interactive effects potentially correlated with the independent variables. We provide conditions under which the slope parameter estimator is asymptotically Gaussian. Monte Carlo studies are carried out to investigate the finite sample perfo...

Maddala and Wu (1999) proposed a simple panel unit test using a Fisher type test. We propose using Percival and Walden (2006) approximate maximum likelihood estimator of the fractional integration order with a Fisher type test to create a simple panel fractional integration order test. By combining the estimator and the test with a wavestrap method to obtain critical values, we allow for cross-...

The Japanese electricity industry has experienced regulatory reforms since the mid-1990s. This article measures productivity in Japan’s steam power-generation sector and examines the effect of reforms on the productivity of this industry over the period 1978–2003. We estimate the Luenberger productivity indicator, which is a generalization of the commonly used Malmquist productivity index, usin...

This article promotes the use of panel data methods in nowcasting. shifts focus literature from national to regional nowcasting variables like gross domestic product (GDP). We propose a mixed-frequency VAR model and bias-corrected least squares estimator which attenuates bias fixed effects dynamic settings. Simulations show that forecast selection combination are successfully adapted setting. O...
