Development economics in the context of "Amartya Sen"

Wealth is the abundance of valuable financial assets or physical possessions which can be converted into a form that can be used for transactions. This includes the core meaning as held in the originating Old English word weal, which is from an Indo-European word stem. The modern concept of wealth is of significance in all areas of economics, and clearly so for growth economics and development economics, yet the meaning of wealth is context-dependent. A person possessing a substantial net worth is known as wealthy. Net worth is defined as the current value of one's assets less liabilities (excluding the principal in trust accounts).

At the most general level, economists may define wealth as "the total of anything of value" that captures both the subjective nature of the idea and the idea that it is not a fixed or static concept. Various definitions and concepts of wealth have been asserted by various people in different contexts. Defining wealth can be a normative process with various ethical implications, since often wealth maximization is seen as a goal or is thought to be a normative principle of its own. A community, region or country that possesses an abundance of such possessions or resources to the benefit of the common good is known as wealthy.

Import substitution industrialization (ISI) is a protectionist trade and economic policy that advocates replacing foreign imports with domestic production. It is based on the premise that a country should attempt to reduce its foreign dependency through the local production of industrialized products. The term primarily refers to 20th-century development economics policies, but it has been advocated since the 18th century by economists such as Friedrich List and Alexander Hamilton.

ISI policies have been enacted by developing countries with the intention of producing development and self-sufficiency by the creation of an internal market. The state leads economic development by nationalization, subsidization of manufacturing, increased taxation, and highly protectionist trade policies. In the context of Latin American development, the term "Latin American structuralism" refers to the era of import substitution industrialization in many Latin American countries from the 1950s to the 1980s. The theories behind Latin American structuralism and ISI were organized in the works of economists such as Raúl Prebisch, Hans Singer, and Celso Furtado, and gained prominence with the creation of the United Nations Economic Commission for Latin America and the Caribbean (UNECLAC or CEPAL). They were influenced by a wide range of Keynesian, communitarian, and socialist economic thought, as well as dependency theory.

Agricultural economics is an applied field of economics concerned with the application of economic theory in optimizing the production and distribution of food and fiber products. Agricultural economics began as a branch of economics that specifically dealt with land usage. It focused on maximizing the crop yield while maintaining a good soil ecosystem. Throughout the 20th century the discipline expanded and the current scope of the discipline is much broader. Agricultural economics today includes a variety of applied areas, having considerable overlap with conventional economics. Agricultural economists have made substantial contributions to research in economics, econometrics, development economics, and environmental economics. Agricultural economics influences food policy, agricultural policy, and environmental policy.

Sir Hans Wolfgang Singer (29 November 1910 – 26 February 2006) was a German-born British development economist best known for the Prebisch-Singer thesis, which states that the terms of trade move against producers of primary products. He is one of the primary figures of heterodox economics.
