Ordoliberalism

Ordoliberalism holds that markets do not arise spontaneously and cannot police themselves: competition is a fragile public good that a strong state must deliberately construct and defend through a legal and constitutional framework — what the Freiburg School called the 'economic order' (Ordnung).

Its core is Eucken's distinction between the rules of the game and the moves within it. The state's job is to set and enforce the rules — above all to prevent the private concentrations of economic power, the cartels and monopolies, that destroy competition from within — but not to direct outcomes, plan production, or pick winners. Röpke added a moral and social dimension, worrying about the human costs of an unmoored, purely commercial society.

It is not a theory that stayed on paper: it became the intellectual basis of the West German 'social market economy' after 1948, guiding Ludwig Erhard's currency reform and the postwar Wirtschaftswunder, and it still shapes German and European Union competition policy, central-bank independence, and the 'stability culture' behind the euro.

It differs sharply from later Anglo-American market liberalism on the role of the state. Where neoliberalism tends to treat state and market as opposites and to want the state small, ordoliberalism insists that a weak state produces not free markets but cartels — so a powerful, rule-bound state is the precondition of competition, not its enemy.

Critics on the left argue that its rule-based rigor becomes an alibi for austerity, binding governments to balanced budgets and price stability even amid mass unemployment, as in the eurozone crisis after 2010; critics on the right find its regulatory ambition still too interventionist.

Because it combines pro-market and pro-state commitments, it is easily misfiled as either ordinary conservatism or watered-down socialism, when its distinctive claim is narrower and sharper: that the market is a constitutional order the state must author and guard.
