Political Economy and Its Impact on Peace and Conflict

Why do some conflicts seem to erupt again and again in the same regions, while peace feels permanent in others? The political economy approach offers a powerful answer. Instead of treating wars and social unrest as random outbreaks of hatred or as failures of individual leaders, it argues that the way wealth, resources, and economic power are distributed across the world is itself a major cause of conflict. This perspective sits at the intersection of economics and politics, and it asks an uncomfortable question: who profits from the way our economies are organised, and who pays the price?

What the political economy approach actually means 🔗

The political economy approach to peace and conflict studies examines how economic structures, resource distribution, and institutional arrangements shape the way conflicts begin, escalate, and either end or persist. It rejects the idea that economics and politics can be studied separately. Instead, it treats them as deeply linked, arguing that economic factors and political processes together shape the dynamics of peace and conflict.

At its core, this approach holds that conflict is rarely just about ideology, religion, or ethnicity, even when it appears that way on the surface. Behind many of these visible triggers lie material interests: control over land, minerals, trade routes, labour, and markets. A useful insight from this tradition is that war creates winners and losers. A state of war can justify the use of violence to create or sustain economic profit and political power, which means that some actors may have a genuine economic incentive to keep a conflict going rather than to resolve it.

This is why the political economy approach pays close attention to the structures that produce inequality. When a small group controls most of a society’s wealth and the institutions that govern it, the result is not just poverty but a system of power that the disadvantaged have little ability to change peacefully.

Why economics and politics cannot be separated 🔗

Consider how economic power translates into political power. Those who control the means of production also tend to shape the laws, institutions, and dominant ideas of a society. This is a foundational claim of the approach: economic dominance and political dominance reinforce each other. When this happens, formal democracy can coexist with deep structural inequality, because the rules of the game are written by those who already hold economic advantages. Understanding conflict, then, requires looking at who holds economic power and how they use the state to protect it.

The Marxist roots of the approach 🔗

Much of the political economy approach traces back to Karl Marx and the thinkers who built on his work. Marx argued that capitalist societies are fundamentally divided into two opposing classes: the bourgeoisie, who own the means of production, and the proletariat, who must sell their labour to survive. According to this view, the capitalist class exploits workers by paying them less than the value they contribute to production, and this systemic inequality is built into the structure of capitalism itself rather than being an accident.

For Marx, this exploitation was the root of class struggle. He saw conflict between classes not as an occasional disturbance but as the central engine of historical change. The tension between those who own and those who work was, in his analysis, permanent until the structure that produced it was transformed.

From class struggle to social unrest 🔗

The Marxist lens helps explain why economic disparity so often becomes social conflict. When workers experience stagnant wages while profits accumulate elsewhere, when the gap between rich and poor widens, and when the institutions meant to protect people seem to serve the powerful, frustration builds. Marx believed that as class consciousness developed, the working class would recognise its shared interests and organise to challenge the existing order.

You do not have to accept Marx’s revolutionary conclusions to find this analysis useful. Contemporary forms of unrest, from labour strikes to mass protests over the cost of living, often reflect the same underlying dynamic he identified: a structural divide between those who control resources and those who depend on them. The framework remains one of the most influential tools for understanding why economic grievances turn into political conflict.

How free markets can deepen inequality 🔗

A central concern of the political economy approach is that unregulated free market economies, left to themselves, tend to concentrate wealth rather than spread it. Markets are efficient at generating growth, but they do not automatically distribute the gains fairly. When the benefits of economic activity flow disproportionately to those who already own capital, inequality grows over time.

This does not mean markets are inherently bad. It means that without deliberate policies to manage distribution, market forces can widen the gap between the wealthy and everyone else. In developed economies, this often shows up as high-skilled workers benefiting from new opportunities while low-skilled workers face competition that suppresses their wages, hollowing out the middle class. In poorer economies, the effects can be even sharper, because weaker institutions are less able to cushion the impact.

The link between inequality and instability 🔗

High inequality is not just unfair; it is destabilising. Economists studying developing economies have noted that already-high inequality makes effective conflict management much harder. When large sections of a population feel locked out of prosperity, the political costs of inequality rise, and societies become more vulnerable to populist backlash, polarisation, and unrest. The economic structure, in other words, sets the stage on which political conflict plays out.

Globalization and the marginalization of the vulnerable 🔗

The political economy approach becomes especially relevant when we look at the global scale. Globalization, the deepening integration of economies through trade, investment, and finance, has produced enormous wealth. But the gains have not been shared evenly. The benefits have tended to concentrate among the wealthiest nations and individuals, while many of the world’s poorest have been left behind.

Research on this has produced mixed but sobering findings. Some studies show that under the right conditions trade and investment can reduce poverty, yet a large body of evidence suggests that globalization has been accompanied by rising inequality within developing countries, offsetting some of the gains the poor might otherwise have enjoyed. The poor, in short, do not always share in the rewards of greater trade.

Why the gap between rich and poor nations matters 🔗

One of the most striking observations is that the gap between the richest and poorest countries has widened over decades. Studies of marginalised economies have traced this growing divide back to the 1960s, identifying dozens of countries that have effectively been left behind by the increased globalization of trade, investment, and finance. For these economies, integration into the world system has not automatically meant catching up. Many remain stuck exporting raw materials and cheap labour while the high-value parts of the economy stay elsewhere.

Dependency and world-systems theory 🔗

To explain this persistent global inequality, the political economy approach draws heavily on dependency theory and world-systems theory. Dependency theory argues that resources flow from a periphery of poor and exploited states to a core of wealthy states, enriching the latter at the expense of the former. The poverty of poor nations, in this view, is not a starting condition they have simply failed to escape; it is actively produced by the way they are integrated into the global economy.

Building on this, Immanuel Wallerstein developed world-systems theory, which divides the global economy into three zones: the core, the semi-periphery, and the periphery. The core nations dominate global economic activity and concentrate wealth and technology, while peripheral nations are marginalised, mainly exporting raw materials and relying on labour-intensive industries. The semi-periphery sits in between, acting as a buffer. This framework helps explain why some regions experience repeated instability: they occupy a structurally disadvantaged position in a global system that channels wealth upward.

Resources, profit, and the duration of conflict 🔗

The political economy approach also sheds light on why certain conflicts last so long. Studies of civil wars have found that dependence on natural resources, especially minerals that are easy to extract and sell, is strongly associated with the duration of civil wars rather than simply their onset. The logic is direct: when resource wealth can finance the actors who sustain a conflict, there is money to be made in keeping the fighting alive. Peace becomes less profitable than war for those in control, which is why understanding the economics of a conflict is essential to ending it.

Toward equitable reform and lasting peace 🔗

If unequal economic structures generate conflict, then lasting peace requires addressing those structures rather than merely stopping the violence. This is the constructive heart of the political economy approach. It points toward reforms aimed at distribution and inclusion rather than growth alone.

Scholars working in this tradition have suggested a range of measures. For marginalised economies, these include greater resource transfers, debt relief, support for building institutional capacity, and reduced trade barriers on goods entering wealthy markets, so that the more marginalised economies can actually benefit from globalization rather than being excluded by it. At the broader level, fair trade rules, progressive tax reform, and wider access to education are frequently proposed as ways to soften the inequality that globalization can otherwise intensify.

Importantly, the approach increasingly emphasises that solutions cannot simply be imposed from outside. Peace efforts that ignore local realities and treat war-torn societies as passive recipients of external engineering tend to fail. A more durable path involves the inclusive participation of local actors, allowing communities to decide how, and how far, they integrate into the global economy. Equitable reform, in this sense, is not just about transferring money but about redistributing power and agency.

Why the approach still matters 🔗

The political economy approach reminds us that peace is not simply the absence of fighting. A society can be free of open war yet still be torn by the structural violence of poverty, exploitation, and exclusion. By focusing attention on who controls wealth and how that control is maintained, this approach pushes us to ask whether a given peace is genuine and stable, or merely a quiet that masks deep inequality waiting to erupt. It connects the everyday economics of wages and prices to the largest questions about war and order, which is precisely why it remains a vital lens in peace and conflict studies.

What do you think? Can lasting peace ever be achieved without first reducing the deep economic inequalities that exist both within and between nations? And when powerful actors profit from ongoing conflict, what realistic incentives could persuade them to choose peace instead?
