The asymptotic distribution of all unit root test statistics depend on the deterministic specification of the fitted test regression, which need not be equal to the true one. In time series, this implies that different deterministic specifications have their own critical values, whereas in panels, it implies that different specifications have their own mean and variance correction factors. This...

Maximum Likelihood Estimation and Lagrange Multiplier Tests for Panel Seemingly Unrelated Regressions with Spatial Lag and Spatial Errors: An Application to Hedonic Housing Prices in Paris This paper proposes maximum likelihood estimators for panel seemingly unrelated regressions with both spatial lag and spatial error components. We study the general case where spatial effects are incorporated...

Stimulating Local Public Employment: Do General Grants Work? The effectiveness of public funds in increasing public employment has long been a question on public and labor economists’ minds. In most federal countries local governments employ large fractions of the working population, meaning that a tool for stimulating local public employment can substantially affect the overall unemployment le...

An IV approach, using as instruments nonlinear transformations of the lagged levels, is explored to test for unit roots in panels with general dependency and heterogeneity across cross-sectional units. We allow not only for the cross-sectional dependencies of innovations, but also for the presence of cointegration across cross-sectional levels. Unbalanced panels and panels with differing indivi...

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...

We show that personality traits mediate the effect of income on Life Satisfaction. The effect is strong in the case of Neuroticism, which measures the sensitivity to threat and punishment, in both the British Household Panel Survey and the German Socioeconomic Panel. Neuroticism increases the usually observed concavity of the relationship: Individuals with higher Neuroticism score enjoy income ...

This paper applies the Phillips and Sul (2007) method to test for convergence in stock returns to an extensive dataset including monthly stock price indices for five EU countries (Germany, France, the Netherlands, Ireland and the UK) as well as the US over the period 1973-2008. We carry out the analysis on both sectors and individual industries within sectors. As a first step, we use the Stock ...

This study examines the convergence patterns of Euro Area (EA) 17 countries’ sovereign bond yield spreads (relative to German bund) over the period of March 2002 to December 2015, by employing the convergence algorithm developed by Phillips and Sul (2007). The empirical findings suggest rejection of full convergence across the EA17 countries’ bond yields spreads, and the presence of a certain n...

This study investigates the relationships among pollutant emissions, energy consumption and economic development in China during the period 1982-2007 by using one-step GMM-system model under multivariable panel VAR framework, controlling for capital stock and labor force. Regarding the data for all 28 provinces as a whole, we find that there is a unidirectional positive relationship running fro...
