English Marginalism William Stanley Jevons – (1835 – 1882) – assisted Menger and Walras in launching the Marginalist Revolution that would eventually lead to the birth of neoclassical economics. Jevons promoted the concept that logical problems can be resolved exactly like equations in algebra by making the statements symbolic and then substituting elements with similar properties. Outlined the principle of diminishing marginal utility and related it to the equimarginal principle. Also introduced the disutility of labor theory and the time- dependent theory of capital. -Heavy contributions to macroeconomic theory, business cycle theory, supply and demand, utility - price determined by demand, if profit exists, more would be produced in the future. - found that once produced P = demand Nassau William Senior – (1790 – 1864) - Senior can be credited with the introduction of the utility-based demand and the cost of production-based supply scheme into economic thought in Great Britain.
