Developmental economics

Development economics is a branch of economics which deals with economic aspects of the development process in low-income countries. Its focus is not only on methods of promoting economic development, economic growth and structural change but also on improving the potential for the mass of the population, for example, through health, education and workplace conditions, whether through public or private channels.

Development economics involves the creation of theories and methods that aid in the determination of policies and practices and can be implemented at either the domestic or international level. This may involve restructuring market incentives or using mathematical methods such as inter-temporal optimization for project analysis, or it may involve a mixture of quantitative and qualitative methods.

Unlike in many other fields of economics, approaches in development economics may incorporate social and political factors to devise particular plans. Also unlike many other fields of economics, there is no consensus on what students should know. Different approaches may consider the factors that contribute to economic convergence or non-convergence across households, regions, and countries.

The earliest Western theory of development economics was mercantilism, which developed in the 17th century, paralleling the rise of the nation state. Earlier theories had given little attention to development. For example, Scholasticism the dominant school of thought during medieval feudalism, emphasized reconciliation with Christian theology and ethics, rather than development. The 16th- and 17th-century School of Salamanca, credited as the earliest modern school of economics, likewise did not address development specifically.

Major European nations in the 17th and 18th century all adopted mercantilist ideals to varying degrees, the influence only ebbing with the 18th-century development of physiocrats in France and classical economics in Britain. Mercantilism held that a nation's prosperity depended on its supply of capital, represented by bullion (gold, silver, and trade value) held by the state. It emphasised the maintenance of a high positive trade balance (maximising exports and minimising imports) as a means of accumulating this bullion. To achieve a positive trade balance, protectionist measures such as tariffs and subsidies to home industries were advocated. Mercantilist development theory also advocated colonialism.
