Finance is a sector of the economy that deals with money – that is, financial management and investment management. The organisations responsible for finance include banks, hedge-funds, and regulators. To properly understand the circulation of money, and to manage this profitably, you need to have a detailed technical understanding of various fiscal instruments, and of the processes by which these are constructed, tracked, and exchanged. The various Masters in Finance (MFin, MSF, MSc) are designed to provide students with precisely this sort of training. Many also offer electives in more qualitative topics, such as business management, while some (especially the MSc) concentrate solidly on the more technical aspects of economic modelling and financial planning.
