Historians credit the School with anticipating subjective value theory and an early quantity theory of money, but the reference literature says it is difficult to give a precise evaluation of the School's influence: later authors, especially Protestant writers hostile to Jesuit and Catholic sources, had ideological motives to conceal where their ideas came from, and even the authorship of Grotius's natural law work was disputed as either original or copied from Suarez and other Spanish authors, showing how credit for this era's ideas was contested and obscured rather than openly traced.
What would resolve this A documented citation chain or manuscript evidence showing a specific later economist (Cantillon, Turgot or Smith) directly read and drew on a named Salamancan text, rather than a general resemblance of ideas.
