This paper studies the asymptotic properties of the semiparametric estimator considered by Pagan and Ullah (1988) and Pagan and Hong (1991) for models with risk terms. We show that when the risk term is nonparametrically specified, the estimator with generated regressors suggested by Pagan and...

This paper derives several Lagrange Multiplier tests for the unbalanced nested error component model. Economic data with a natural nested grouping include firms grouped by industry; or students grouped by schools. The LM tests derived include the joint test for both effects as well as the test...

This paper derives two simple artificial Double Length Regressions (DLR) to test for spatial dependence. The first DLR tests for spatial lag dependence while the second DLR tests for spatial error dependence. Both artificial regressions utilize only least squares residuals of the restricted...

Using dynamic panel data techniques and several data sets, we provide new evidence on the effects of openness and institutions on financial development. Our findings suggest that openness and institutions are potentially very important factors for different aspects of financial development. They...

This paper uses 336 state tax changes across the U.S. spanning 42 years (1956–1997) to provide an updated look at the quasi-experimental price elasticities of cigarette demand. It also studies the sensitivity of these elasticity estimates to changes in the cigarette market over time as well as...

This paper reconsiders the Polish wage curve using individual data from the Polish Labor Force Survey (LFS) at the 16 NUTS2 level allowing for spatial spillovers between regions. In addition it estimates the total and gender-specific regional unemployment rate elasticities on individual wages....

This paper studies test of hypotheses for the slope parameter in a linear time trend panel data model with serially correlated error component disturbances. We propose a test statistic that uses a bias corrected estimator of the serial correlation parameter. The proposed test statistic which is...
