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...

In this paper, we discuss the possible effects of Poland's accession to the European Union (EU) on the economic development of the Polish eastern border regions. In accordance with the theoretical previsions, economic integration may have a great impact on the spatial allocation of economic...

This paper reconsiders the Brazilian wage curve using individual data from the National Household Survey at 27 Federative Units over the period 2002 - 2009. We find evidence in favor of the Brazilian wage curve with an unemployment elasticity of -0.08 when the lagged unemployment rate is used as...

This paper analyzes the Polish wage curve using individual data from the Polish Labor Force Survey (LFS) at the 16 NUTS2 regions over the period 1999 - 2010. This survey does not gather information on wages of self-employed or paid family workers. After excluding the unemployed, inactive and...

In this paper, we test empirically for the increasing returns-based agglomeration and investigate the impact of the economic integration with the European Union on regional wage inequalities in Poland. In our study, we use the wage data for 16 Polish regions over the period of 1995-2009. Our...

This article aims at verifying the role of interregional transport infrastructure in the development of Polish regions. We use the modified model of economic potential to identify the regions with the highest values of economic potential where metropolitan areas can be developed. Subsequently,...

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....

Building upon the work of Chen et al. (2010), this paper proposes a test for sphericity of the variance-covariance matrix in a …xed e¤ects panel data regression model without the normality assumption on the disturbances.

This paper develops the adaptive elastic net GMM estimator in large dimensional models with many possibly invalid moment conditions, where both the number of structural parameters and the number of moment conditions may increase with the sample size. The basic idea is to conduct the standard GMM...
