The Revival of Institutional Approach: New Institutionalism in Comparative Politics

For much of the early twentieth century, political scientists studied government by examining constitutions, laws, and formal structures. Then the behavioural revolution pushed institutions aside, treating them as mere “black boxes” and focusing instead on individual actions and measurable behaviour. By the 1980s, scholars realised that neither approach alone could fully explain why political systems behaved so differently across countries. This realisation gave rise to New Institutionalism, a framework that brought institutions back to the centre of comparative analysis while keeping the analytical rigour the behaviouralists had introduced. Understanding this revival is essential for anyone trying to make sense of how rules, norms, and structures actually shape politics.

Why institutions made a comeback 🔗

The story of New Institutionalism is really a story of correction. The traditional institutional approach dominated political science until the mid-twentieth century, concentrating almost entirely on formal governmental machinery like legislatures, executives, and judiciaries. After the Second World War, this approach lost ground as behaviouralists argued that politics should be studied scientifically through quantitative methods and the observable behaviour of individual actors.

But by the 1980s, the limits of pure behaviouralism were becoming obvious. Studying individual choices in isolation ignored the context in which those choices were made. The new institutionalist approach took root in the early to mid-1980s, when many political scientists began questioning whether you could really understand a member of parliament’s vote without understanding the rules of the legislature itself. The revival was not entirely “new,” however. As scholars have noted, it was less a fresh invention than a restatement of older insights, now combined with modern analytical tools.

The founding contribution of March and Olsen 🔗

The intellectual turning point came with the work of American political scientist James G. March and Norwegian political scientist Johan P. Olsen. Their influential 1984 article and their 1989 book brought institutions back as a central explanatory factor. They argued that institutions are not simply arenas where political actors compete. Instead, institutions actively shape the preferences, identities, and behaviour of those actors. This was a decisive break from the view that politics is just the sum of individual choices.

What counts as an institution now 🔗

One of the most important shifts New Institutionalism introduced was a much broader definition of what an institution actually is. The old approach looked only at formal structures: written constitutions, statutory bodies, and official procedures. The new approach widened the lens considerably.

Under New Institutionalism, institutions include formal rules, organisational structures, and informal norms that constrain and enable political behaviour. This means an institution can be a written law in the Constitution, but it can equally be an unwritten convention that everyone follows out of habit or social expectation. Both kinds matter, and both influence outcomes.

Consider how this plays out in practice. Caste-based discrimination is formally prohibited under the Constitution, yet informal institutions built around caste identity continue to shape voting patterns, candidate selection, and coalition building. A purely formal-legal analysis would miss this entirely. New Institutionalism captures both layers, showing how the formal rule and the informal practice interact to produce real political behaviour.

The two-way street between institutions and actors 🔗

A defining feature of New Institutionalism is its emphasis on the dynamic interaction between institutions and individuals. Institutions are not fixed cages that simply trap actors inside them. They both constrain and enable political action, and they are in turn reshaped by the very actors operating within them.

The anti-defection law offers a clear example. It creates institutional pressure for party discipline, shaping how members of Parliament vote. Yet over time, the way parties use and interpret this law has itself reshaped how the institution functions. The relationship runs in both directions, which is exactly the kind of complexity the older static models could not explain.

The three faces of New Institutionalism 🔗

New Institutionalism is not a single, unified theory. It is better understood as a family of related approaches. In their landmark 1996 article, Peter Hall and Rosemary Taylor organised the field into three distinct schools: historical institutionalism, rational choice institutionalism, and sociological institutionalism. Each offers a different lens on how institutions shape politics, and together they provide a rich toolkit for comparative analysis.

Historical institutionalism 🔗

Historical institutionalism stresses that the past matters enormously for the present. Its central claim is that timing, sequences, and path dependence shape institutions and the behaviour that flows from them. Once an institution is established, it tends to create self-reinforcing patterns that become difficult to reverse, even when the arrangement turns out to be inefficient.

This school highlights two key ideas. The first is path dependence, the notion that early institutional choices lock societies onto particular trajectories. The second is the importance of critical junctures, moments of significant disruption when genuine institutional change becomes possible. Historical institutionalists also pay close attention to the asymmetries of power embedded in institutions, recognising that institutions often benefit some groups far more than others.

India offers a striking illustration. A study of the country’s economic liberalisation argues that a layered evolution of ideas through the 1980s led to a tipping point in 1991, when policy goals were fundamentally transformed for largely internal reasons. The gradual accumulation of changes within the bureaucracy eventually displaced the older public-sector-driven regime, demonstrating how path-dependent processes can produce dramatic change that looks abrupt but was actually building for years.

Rational choice institutionalism 🔗

Rational choice institutionalism approaches institutions from a very different angle. It treats political actors as goal-oriented individuals seeking to maximise their interests. The key insight is that institutions provide information to actors and structure their strategic interaction. Rules reduce uncertainty, shape expectations about what others will do, and thereby make stable outcomes possible.

This school grew partly out of attempts to explain why legislatures produce stable majorities rather than constant chaos. The answer, rational choice scholars argued, lay in institutions: the rules of procedure, the committee systems, and the agenda-control mechanisms that structure the choices available to legislators. By shaping incentives, these institutional rules channel self-interested behaviour into predictable patterns.

Electoral systems are a useful application here. India’s first-past-the-post system for Lok Sabha elections rewards strategic voting and alliance formation, encouraging parties to build broad coalitions. The institutional rules of the electoral system create specific incentives, and rational actors respond to them in calculable ways.

Sociological institutionalism 🔗

Sociological institutionalism emphasises culture, meaning, and identity. Rather than viewing actors as pure calculators of material self-interest, this school argues that what an individual sees as “rational action” is itself socially constituted. Institutions, in this view, supply the cognitive scripts and templates through which people interpret their world and decide what counts as appropriate behaviour.

Hall and Taylor offer a memorable observation to capture this point: anyone who has waited at a red traffic light when no one else is around recognises that there are dimensions to the relationship between institutions and action that material calculation cannot fully explain. People often follow institutional rules simply because doing so feels right, normal, or socially expected, not because they have calculated a payoff.

This perspective is particularly powerful for understanding how institutions create meaning and shape collective identities. It explains why certain practices persist long after their practical usefulness has faded, surviving because they have become embedded in how a society understands itself.

Why methodological diversity is a strength 🔗

One reason New Institutionalism became so influential in comparative politics is precisely because it draws on these diverse methodologies. Rather than insisting on a single correct way to study institutions, it accommodates structural analysis, strategic modelling, and cultural interpretation under one broad umbrella.

Hall and Taylor’s careful separation of the three schools provided much-needed clarity to a field that had previously been confused about what institutional analysis even meant. Their work, cited thousands of times, established a foundational typology that continues to guide research and fosters productive dialogue across political science, sociology, and economics.

New Institutionalism in comparative analysis 🔗

The real test of any framework is its usefulness, and here New Institutionalism has proven its worth repeatedly. It has become a central tool for explaining why political outcomes vary so dramatically across different institutional contexts. Researchers have used it to compare institutional configurations across countries, to analyse electoral systems and party politics, and to evaluate how bureaucratic reform affects policy implementation.

The framework is also valuable for studying institutional change and stability together, rather than treating them as separate puzzles. A study of minority policy reform in India shows how the “stickiness” of existing institutional arrangements constrained the scope of possible change. Decades of accumulated policy choices created such robust path dependence that even determined reform efforts struggled to establish a new equilibrium. This kind of analysis, which links historical legacies to present-day political constraints, captures the explanatory richness that earlier approaches lacked.

A synthesis that endures 🔗

What makes New Institutionalism so durable is that it refuses to choose between structure and agency. The behaviouralists were right that individual behaviour matters, and the traditional institutionalists were right that structures matter. New Institutionalism’s achievement was recognising that these two insights are not rivals but partners. Institutions shape actors, and actors reshape institutions, in a continuous and dynamic process.

This synthesis explains why the approach has remained relevant for over four decades. As comparative politics continues to grapple with questions of democratic stability, institutional reform, and cross-national variation, the New Institutionalist framework keeps offering fresh analytical leverage. It reminds us that to understand politics, we must look beyond both formal rule books and isolated individual choices, and examine instead the complex interplay of rules, norms, and behaviour that constitutes political life.

What do you think? Which of the three institutionalisms best explains the political phenomena you find most puzzling in your own country? And can informal institutions like caste, kinship, or social convention ever be reformed through formal legal change alone?
