The forces that shape economic growth: --The size of markets. Large markets make economies of scale possible and thus encourage saving, investing, and the development of new products.--The availability of information and the literacy of the population. The spread of information gives people access to scientific and technical ideas, products, and productive farming, manufacturing, and marketing techniques.--Natural resources. These seem like primary requirements but are not: they depend on markets for their commercial value.--Surplus capital--savings--that can be used as investment.--Basic economic rights such as guarantees of property and contracts.--Entrepreneurialism, creativity, and the human drive for self-improvement.--Technology and invention. While commonly seen as primary (or even the only) requirements for growth, these are strongly dependent on other factors.
