Economic development generally refers to the sustained, concerted actions of policymakers and communities that promote the standard of living and economic health of a specific area. Economic development can also be referred to as the quantitative and qualitative changes in the economy. Such actions can involve multiple areas including development of human capital, critical infrastructure, regional competitiveness, environmental sustainability, social inclusion, health, safety, literacy, and other initiatives.

According to Malthusian theory of population, population increases in a geometrical ratio, whereas food supply increases in an arithmetic ratio. This disharmony would lead to widespread poverty and starvation, which would only be checked by natural occurrences such as disease, high infant mortality, famine, war or moral restraint.

The UNIVAC computer was the first commercially available computer invented by John Presper Eckert and John Mauchly. As well as being the first American commercial computer, the UNIVAC I was the first American computer designed at the outset for business and administrative use (i.e., for the fast execution of large numbers of relatively simple arithmetic and data transport operations, as opposed to the complex numerical calculations required by scientific computers). As such the UNIVAC competed directly against punch-card machines (mainly made by IBM).

Supply of labour in an economy depends upon both economic as well as non-economic factors. It depends upon the size of population, the number of workers available for work out of a given population, the number of hours worked, the intensity of work, the skills of workers, their willingness to work and the mobility of labour.

Heavy selling cost is one of the defining features of an oligopoly. Firms resort to heavy selling cost to attract customers. Under this market form, the firms have to compete to promote their sale by largely homogenous products, differentiated mainly by heavy advertising and promotional expenditure that ultimately adds to the total selling cost.
