It is certain that the government plays a role in economic development. Researchers \citep*{Hall_1999} have shown that variations in income per capita across nations can hardly be explained by capital accumulation, which is suggested by classical growth theory; instead, differences in economic outcomes are largely associated with so-called social infrastructure, such as institutions and government policies. Failure of establishing efficient government generally results in failure of development (for example, the sluggish development in Africa is the consequence of government failure).
