Development economics

Development economics is like the study of how countries can become wealthier and improve their people's lives. To do this, economists look at the economy of a country and figure out ways to help it grow and make more money. This could be done by encouraging people to start businesses, start more factories, or invest in new technologies. By doing these things, people can create more jobs and get more money. This money can then be used to provide better healthcare, education, and other services that help people's lives become better.
