The effect of government expenditure on the environment: An empirical investigation. Ecological Economics 91(C): 48-56 (SCOPUS, EconLit, ISI Listed. Impact factor: 2,720 and 5-year 3,929). In common with Ε. Paizanos (2013).

This paper examines the impact of government spending on the environment using a panel of 77 countries for the time period 1980-2000.  We estimate both the direct and indirect effects of government spending on pollution. The indirect effect in particular operates through the impact of government spending on income and the subsequent effect of the income level on pollution. To take into account the dynamic nature and the potential endogeneity in the relationships examined, appropriate econometric methods are used. For SO2, government spending is estimated to have a negative direct impact on per capita emissions, while the direct effect is insignificant on CO2 pollution. The indirect effect on SO2 is negative for low income levels and becomes positive as income increases, while it remains negative for CO2 for the most part of the sample range. The resultant total effects follow the patterns of the indirect effects, which dominate their respective direct ones for each pollutant. Policy implications from the results vary depending on the income level of the considered countries.
