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 growth and structural change but also on improving the potential for the mass of the population, for example, through health and education and workplace conditions, whether through public or private channels. Thus, development economics involves the creation of theories and methods that aid in the determination of types 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 like 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. Different approaches may consider the factors that contribute to economic convergence or non-convergence across households, regions, and countries.

Some well-known examples are the King's Gambit (1.e4 e5 2.f4), Queen's Gambit (1.d4 d5 2.c4), and Evans Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4). A gambit used by Black may also be called a gambit (e.g., Latvian Gambit (1.e4 e5 2.Nf3 f5), Englund Gambit (1.d4 e5), but is sometimes called a "countergambit" (e.g., Albin Countergambit) (1.d4 d5 2.c4 e5) or Greco Counter-Gambit, an old-fashioned name for the Latvian Gambit). The word "gambit" was originally applied to chess openings in 1561 by Spanish priest Ruy Lopez de Segura, from an Italian expression dare il gambetto (to put a leg forward in order to trip someone). Lopez studied this maneuver, and so the Italian word gained the Spanish form gambito that led to French gambit, which has influenced the English spelling of the word. The broader sense of "opening move meant to gain advantage" was first recorded in English in 1855.
