"Value manifests itself as exchange value, as a quantitatively determined relationship, in virtue of the fact that one commodity can be exchanged for another"

Rudolf Hilferding's quote delves into the concept of exchange worth in the context of products. To translate this, it's important to separate the ideas of "value" and "exchange value", which are fundamental in Marxist financial theory.

Initially, the term "worth" in a Marxist sense refers to the labor embedded in a product. It's a measure of the socially needed labor time needed to produce a product. This worth, nevertheless, doesn't manifest on its own in a capitalist economy; rather, it appears in the form of "exchange worth."

Exchange worth is the symptom of a product's worth in the market, where it's expressed as a quantitative ratio at which one product can be traded for another. This idea highlights the commodity's ability to be exchanged, and its quantitative decision is because of the relative worth of labor ingrained in various products. For instance, if product A can be exchanged for product B at a particular ratio, this reflects their exchange worth, representing the labor time socially required for their production.

Hilferding emphasizes that exchange value is considerable due to the fact that it enables different products to connect within the market system. It enables the transformation of use worth, which is the energy or usefulness of a product, into a kind that can assist in sell a capitalist economy.

In summary, Hilferding's declaration lays out the double nature of value: as an intrinsic quality stemmed from labor, and as exchange value, the relational, quantitative expression of a product's worth in the market. This duality is central to comprehending how products function within industrialism, assisting in the detailed system of exchanges that comprises the financial landscape. Through this lens, commodities become the foundation of market economies, in which their worth becomes a network of relationships governed by the labor bought them.
