Institutions, Institutional Change and Economic Performance

North introduced path dependence as the mechanism. He argued that institutions create incentive structures that foster specific organizational skills and knowledge. Organizations then invest in those skills, creating increasing returns and powerful constituencies that reinforce the existing framework. This explains why economies can become locked into stagnation even when superior institutional arrangements are theoretically available—the feedback loops favor the status quo.

In The Rise of the Western World (1973), North and Thomas emphasized relative price changes as drivers of institutional evolution. In Institutions (1990), North shifted focus to ideology, path dependence, and the persistence of inefficient institutions. He acknowledged that institutions are not always established for social efficiency but instead serve the interests of those powerful enough to establish them, marking a significant departure from his earlier more efficiency-oriented framework[citation:4].

North treats ideology as shared mental models that shape how actors interpret their environment and perceive opportunities. These models matter because purely rational choice under incomplete information cannot fully explain institutional stability or change. Ideology fills the gap, providing a cognitive framework that can either facilitate cooperation or entrench conflict. This concept becomes increasingly prominent in North's later work, particularly Understanding the Process of Economic Change (2005)[citation:4].

Original institutional economists associated with the Veblenian tradition argue that North remains too close to neoclassical assumptions, particularly his reliance on maximizing rationality and market order as the mechanism of human sociability[citation:4]. Critics contend that North's framework lacks a material anchor such as surplus theory, making his theory of institutions progressively more elusive. They argue that power and predatory elites are insufficiently theorized in his transaction-cost approach[citation:15].

North argues that institutions exist because of the uncertainties inherent in human interaction. Transaction costs—the costs of measuring what is being exchanged and enforcing agreements—are central to his explanation. Institutions emerge as constraints devised to structure interaction and reduce these costs. However, North emphasizes that the institutions that emerge are not necessarily efficient; they reflect power distributions and historical contingencies rather than optimal solutions to collective problems.

North treats both as essential, but he emphasizes that informal constraints—customs, traditions, norms of behavior—are far more resistant to deliberate change than formal rules. This asymmetry explains why importing formal institutions from successful economies often fails. The informal institutional matrix embedded in a society's culture and history can subvert or redirect formal rules, producing outcomes different from those intended by reformers.
