Thomas Mayer has argued that, because praxeology rejects positivism and empiricism in the development of theories , it constitutes nothing less than a rejection of the scientific method . For Mayer, this invalidates the methodologies of the Austrian school of economics .   Austrians argue that that empirical data itself is insufficient to describe economics; that consequently empirical data cannot falsify economic theory; that logical positivism cannot predict or explain human action; and that the methodological requirements of logical positivism are impossible to obtain for economic questions.   Ludwig von Mises in particular argued against empiricist approaches to the social sciences in general, because human events are unique and "unrepeatable," whereas scientific experiments are necessarily reducible. 
General equilibrium theory, or Walrasian general equilibrium, attempts to explain the functioning of economic markets as a whole, rather than as individual phenomena. The theory was developed by the French economist Leon Walras. It stands in contrast with partial equilibrium theory, or Marshellian partial equilibrium, which only analyzes specific markets. BREAKING DOWN 'General Equilibrium Theory' Walras developed general equilibrium theory to solve a much-debated problem in economics. Up to that point, most economic analyses only demonstrated partial equilibrium — the price at which supply equals demand and markets clear — in individual markets. It was not yet shown that equilibrium could exist for all markets at the same time.
