másval

Másval is a term that may refer to several related concepts, most commonly as a shortened form of más-valía (also written plusvalía) in Marxist economics. The standard term más-valía designates the surplus value created by labor in a capitalist economy, the difference between the value produced by workers and the wages they receive. In Karl Marx's theory, this surplus value is appropriated by capitalists and forms the basis of profit. The concept is central to critiques of capitalist exploitation and to discussions of labor value and capital accumulation. Marx distinguished different sources of surplus value, including extending the working day (absolute surplus value) and increasing productivity relative to wages (relative surplus value). In Spanish-language scholarship, más-valía or plusvalía are the conventional spellings; másval occasionally appears as an informal or nonstandard abbreviation in some sources.

Beyond economics, másval may appear as a proper noun in Spanish-speaking contexts, where it could function as a surname or place name, though its use in this capacity is uncommon and not well documented in standard reference works. In most academic discussions, the full term más-valía or plusvalía is preferred to avoid ambiguity.
