  Question 87: We know now that value consists of abstract labor. What does exchange-value consist of?   
  [36] Grindage: Marx is trying to describe how the capitalist system has evolved into using money and how it has abstracted out labor.   
  When use-value (labor) becomes abstract and commodities can be exchanged by equating them in terms of a universal equivalency, this is when exchange-value is dominant in the capitalist system.   
  Price is not exchange-value. It is merely a monetary expression of exchange-value. Exchange-value can be thought of as something that relates exchange values of all different commodities.   
  Exchange-value is therefore what is used just before money is used in the capitalist system. Money takes the equivalencies developed by exchange-values and equates universally all commodities and links them through money values.   
  Exchange value is the quantity for which one commodity would taken to be exchanged for a certain quantity of another commodity.   
  Therefore, exchange value consists of how much of a commodity is needed to exchange for another quantity of a commodity. These two quantities of commodities include labor and that will also be included in what exchange-value consists of.
