| Abstract: |
In recent years many empirical studies of environmental Kuznets curves
employing unit root and cointegration techniques have been conducted for both
time series and panel data. When using such methods several issues arise: the
effects of a short time dimension, in a panel context the effects of
cross-sectional dependence, and the presence of nonlinear transformations of
integrated variables. We discuss and illustrate how ignoring these problems
and applying standard methods leads to questionable results. Using an
estimation approach that addresses the second and third problem we find no
evidence for an inverse U-shaped relationship between GDP and CO2 emissions. |
