In this paper we examine temporal properties of eleven natural resource real price series from 1870-1990 by employing a Lagrangian Multiplier unit root test that allows for two endogenously determined structural breaks with and without a quadratic trend. Contrary to previous research, we find...

A panel of industrial countries is examined for evidence of 'tax smoothing'. Tax smoothing results when governments minimize tax distortions over time. The model provides a positive theory of government debt and is due primarily to Barro. Unit root tests are performed in panel data to test the...

The size of government consumption relative to national output is examined to see if it is optimal in five Gulf countries of the Middle East. We follow the methodology suggested in Barro (1990) and Karras (1996, 1997) and examine the marginal productivity of government consumption. The "Barro...

Time paths of carbon dioxide emissions intwenty-one industrial countries are examinedfrom 1960–1997 to test for stochastic andconditional convergence. Both panel unit roottests and cross-section regressions areperformed. Overall, we find significantevidence that CO<Subscript>2</Subscript> emissions haveconverged....</subscript>
