Within this equity and efficiency tradeoff, equity refers to the economy's financial capital, while efficiency refers to the future efficiency in the production of goods and services. This theory asserts that, in order for a nation to become wealthier, it must save its equity. However, these additional savings will hurt the development of more efficient production in the future.
