This page classifies the academic literature on finance into categories. Finance is a branch of economics. Economics can be defined as the study of resource allocation, distribution and consumption; of capital and investment; and of management of the factors of production. The difference between finance and economics is that everything in finance can be reduced to money. This makes matters simpler for finance researchers since money is fungible. Academics in finance usually specialize in one or more areas of finance. Another way of looking at finance is to focus on one of the paradigms of finance.
