This paper proposes simple tests of error cross section dependence which are applicable to a variety of panel data models, including stationary and unit root dynamic heterogeneous panels with short T and large N. The proposed tests are based on average of pair-wise correlation coefficients of...

This paper extends the cross sectionally augmented panel unit root test proposed by Pesaran (2007) to the case of a multifactor error structure. The basic idea is to exploit information regarding the unobserved factors that are shared by other time series in addition to the variable under...

The presence of cross-sectionally correlated error terms invalidates much inferential theory of panel data models. Recently work by Pesaran (2006) has suggested a method which makes use of cross-sectional averages to provide valid inference for stationary panel regressions with multifactor error...

This paper reconsiders the long-run economic relationship between health care expenditure and income using a panel of 20 OECD countries observed over the period 1971-2004. In particular, the paper studies the non-stationarity and cointegration properties between health care spending and income....

This paper provides a review of linear panel data models with slope heterogeneity, introduces various types of random coefficients models and suggest a common framework for dealing with them. It considers the fundamental issues of statistical inference of a random coefficients formulation using...

In line with the neoclassical growth model a persistent stream of oil revenues might have a long lasting impact on GDP per capita in oil exporting countries through higher investment activities. This relationship is explored for Iran and the countries of the Gulf Cooperation Council (GCC) using...

This paper investigates the link between health care expenditures and GDP for a sample of 21 OECD countries using recent developed panel cointegration techniques. In contrast to previous studies, the analysis accounts for the fact that health care expenditures are not only determined by income....

This paper examines the impact of the immigration of foreigners on domestic labour mobility. Since David Card's seminal study on the regional labour market impact of the Mariel Boatlift it is controversial whether domestic labour mobility equilibrates economic conditions across cities and...

International migration is characterized by two puzzling facts: First, only a small share of the population tends to migrate although substantial and persisting income differences across countries exist. Second, net migration rates tend to cease over time despite persisting income differences....
