But which is the best government policy to achieve development is subject to controversy. Varies attempts have been made. However, none of them is satisfactory. For example, the big push model, which views development as a technical issue and as something that can be achieved with a huge amount of international aid (as proposed by the UN Millennium Project), has been criticized because of the little effect of international aid on development \citep*{Easterly_2006}. The laissez-faire policy of development, as advocated by classical economists, however, also seems to be wishful thinking \citep*{Ha_Joon_2012}.
