Finance d'entrepriseLa finance d'entreprise ou gestion financière, est le champ de la finance relatif aux décisions financières des entreprises. Son objet essentiel est l’analyse et la « maximisation de la valeur de la firme pour ses actionnaires envisagée sur une longue période » . En termes plus précis, l'enjeu consiste à optimiser la valeur de la séquence des profits monétaires futurs (relativement à un horizon de référence) sous la contrainte de la limitation des risques courus.

It consists of shareholders' equity, debt (borrowed funds), and preferred stock, and is detailed in the company's balance sheet.

Financial economicsFinancial economics is the branch of economics characterized by a "concentration on monetary activities", in which "money of one type or another is likely to appear on both sides of a trade". Its concern is thus the interrelation of financial variables, such as share prices, interest rates and exchange rates, as opposed to those concerning the real economy. It has two main areas of focus: asset pricing and corporate finance; the first being the perspective of providers of capital, i.e.
