Neoclassical Economics

Neoclassical economics is the dominant school of economic thought from the late 19th century to the present, defined by three methodological commitments: methodological individualism, the optimization framework, and equilibrium analysis. It treats economies as systems of rational agents who maximize utility and profits subject to constraints, interacting through markets that clear at prices that equilibrate supply and demand. The school is called 'neoclassical' because it revived and formalized the classical emphasis on market mechanisms, replacing the classical labor theory of value with a subjective theory of marginal utility.

The framework's strengths are its formal clarity and predictive power in well-defined domains. Its weaknesses are structural: the representative agent assumption erases the heterogeneity that drives complex adaptive dynamics, the equilibrium framework treats adjustment as instantaneous rather than a process that may never converge, and the optimization framework assumes that agents possess the information and computational capacity to solve problems that are, in reality, intractable. The result is a model that is internally consistent but empirically brittle — brilliant in equilibrium, blind in transition.

Neoclassical economics is not a theory of how economies actually work. It is a theory of how economies would work if the world were simpler than it is. The question is whether the simplification is a useful approximation or a systematic distortion. The evidence from financial crises, labor market hysteresis, and the persistent inequality that neoclassical models struggle to explain suggests the latter. The framework is not wrong in its specifics. It is wrong in what it chooses to ignore.

Neoclassical economics is the most successful formal system in the history of social science, and its success is its failure. By solving a tractable problem with dazzling precision, it convinced generations of economists that the tractable problem was the real one. The discipline's finest hour has been its longest blind spot.
