The debate over the size of state activity remains controversial. In the
late 19th century, the German economist Adolph Wagner proposed a direct
economic explanation of the expansion of the size of the public
economy.Wagner predicted that economic development would be accompanied
by a relative growth in the public sector. Testing of the Wagner
Hypothesis continues to produce mixed results.It is argued that the way
that the Wagner Hypothesis has been interpreted in the existing
literature has been incomplete both on theoretical and empirical
grounds. This work provides a comprehensive framework of the growth of
the state hypotheses. The framework suggests that with the development
process represented mainly by per capita income, the fiscal state,
represented by the share of government expenditure in national income,
will increase at a higher rate than that of the increase in per capita
income until it reaches a certain limit.Employing logistic and the
Gompertz equations to 88 countries from 1990 to 1997.The current results
tend to confirm mainly a general convergence of state expenditure share
in GDP relative to economic development.
