CaseStudy - US

• Able to Explain the process of urbanization, industrialization

• Economic development of a nation can be well modelled

• Shows how there is more than one path to development

Strengths

• Assumption that development is linear

• Developed in 1940's and is outdated

• Only takes into account "MEDC"s (that can have different sectors. e.g: some countries have poorer secondary sectors, etc)

• Not valid due to Interdependency - raw materials usage is not equal and Fair amongst nations

• Model doesn't include the international economic context such as imported manufactured goods

Weaknesses
