Conception subjective de la valeurLa conception subjective de la valeur est une conception de la valeur en économie qui postule que, . Elle reconnaît également qu'un objet peut répondre aux besoins d'un individu et non d'un autre. Le voit s'affronter des économistes au sujet de la nature de la valeur et des causes de la valeur. Adam Smith propose une théorie dite de la valeur-travail, c'est-à-dire que la valeur d'un bien correspond à la quantité de travail qui a été requise pour le fabriquer.
Unequal exchangeUnequal exchange is used primarily in Marxist economics, but also in ecological economics (more specifically also as ecologically unequal exchange), to denote forms of exploitation hidden in or underwriting trade. Unequal exchange is usually calculated by assuming that any trade between a country with a high price level and a country with a low price level, is exploitation.
Abstract labour and concrete labourAbstract labour and concrete labour refer to a distinction made by Karl Marx in his critique of political economy. It refers to the difference between human labour in general as economically valuable worktime versus human labour as a particular activity that has a specific useful effect within the (capitalist) mode of production. As economically valuable worktime, human labour is spent to add value to products or assets (thereby conserving their capital value, and/or transferring value from inputs to outputs).
Real prices and ideal pricesThe distinction between real prices and ideal prices is a distinction between actual prices paid for products, services, assets and labour (the net amount of money that actually changes hands), and computed prices which are not actually charged or paid in market trade, although they may facilitate trade. The difference is between actual prices paid, and information about possible, potential or likely prices, or "average" price levels.
Market socialismMarket socialism is a type of economic system involving social ownership of the means of production within the framework of a market economy. Various models for such a system exist, usually involving some mix of public, cooperative, and privately owned enterprises.

Market socialism differs from non-market socialism in that the market mechanism is utilized for the allocation of capital goods and the means of production.
Socialist calculation debateThe socialist calculation debate, sometimes known as the economic calculation debate, was a discourse on the subject of how a socialist economy would perform economic calculation given the absence of the law of value, money, financial prices for capital goods and private ownership of the means of production. More specifically, the debate was centered on the application of economic planning for the allocation of the means of production as a substitute for capital markets and whether or not such an arrangement would be superior to capitalism in terms of efficiency and productivity.
Crisis theoryCrisis theory, concerning the causes and consequences of the tendency for the rate of profit to fall in a capitalist system, is associated with Marxian critique of political economy, and was further popularised through Marxist economics. Earlier analysis by Jean Charles Léonard de Sismondi provided the first suggestions of the systemic roots of Crisis. "The distinctive feature of Sismondi's analysis is that it is geared to an explicit dynamic model in the modern sense of this phrase ...
Économie socialisteL'économie socialiste se réfère aux théories économiques et aux pratiques se rapprochant des courants socialistes. L'économie socialiste se caractérise fondamentalement par la propriété collective des moyens de production, ce qui peut désigner aussi bien les coopératives autonomes que la propriété publique; ce qui implique un autre mode de production.
