Multinationals' Corruption "Learning": How Home-Country Enforcement Reshapes the Global Investment Landscape

Corruption “Learning” by Multinational Corporations: How Home-Country Enforcement Reshapes the Global Investment Landscape

Corruption is regarded as one of the biggest obstacles to global business sustainability. It distorts market pricing, raises transaction costs, and discourages foreign direct investment. Yet, intriguingly, many multinational corporations still proactively enter highly corruption-prone markets and operate there for the long term. Why? The answer may lie in two words: experience. The operational knowledge that firms accumulate in corrupt environments determines whether they next choose to compete "cleanly" or collude "dirtily."

A study recently published by United Nations University (UNU-MERIT), based on more than 91,000 greenfield investment projects covering 101 countries and 25,000 multinational corporations, reveals the deeper logic behind corruption experience and outward investment. The study divides multinationals' learning paths in corrupt markets into two models—"clean hands" and "dirty hands"—and identifies a crucial moderating variable: the intensity of home-country anti-corruption enforcement.

Two Learning Paths, Two Types of Globalization

The so-called "clean hands" model refers to firms developing, when faced with a corrupt institutional environment, the capacity to operate in compliance, to establish internal anti-bribery systems, and to bypass corrupt transactions without breaking the law. This is an institutionalized moral resilience that helps firms adapt to low-quality institutional environments without straying from ethical tracks.

The "dirty hands" model is the opposite. Firms learn how to identify suitable bribe targets, how to make kickback payments covertly, and how to use local corruption networks to gain advantages in contracting. This kind of "survival of the fittest" learning may enhance firms' competitiveness in the short term, but in the long run it erodes corporate governance and exposes them to legal and reputational risks.

The study's key finding is that when home countries strictly enforce laws against overseas bribery, firms' investment behavior in corrupt markets changes systematically. If "clean hands" learning dominates, strict enforcement should encourage experienced firms to continue investing, because their compliance systems are consistent with home-country law. But if "dirty hands" learning is widespread, strict enforcement will suppress investment, because firms realize that the unethical strategies they once relied on are no longer safe. The empirical results point clearly to the latter.

Enforcement Is a Strategic Signal, Not Merely a Legal Tool

This means that when home-country governments enforce laws against overseas bribery domestically, they are not just punishing individual firms; they are sending a clear signal to all multinational corporations: even engaging in unethical behavior in countries with weak judiciaries will not allow them to escape accountability. This signal permeates firms' global strategic decision-making and alters their "learning curve" in corrupt markets.

Looking at the data, the intensity of enforcement by signatories of the OECD Anti-Bribery Convention is significantly correlated with multinationals' investment behavior in highly corrupt countries. The stricter the enforcement, the more multinationals tend to curb or reassess their decisions to enter such markets—especially those firms with prior "dirty hands" experience. They realize that the bribery networks they once knew well may turn into legal traps at any time.This also explains why the recent rollback in U.S. enforcement of the Foreign Corrupt Practices Act has sparked widespread concern in the international business community. When the largest economy in global governance eases enforcement, it sends a signal to global companies that “anti-corruption compliance is no longer a priority.” At the same time, enforcement by several OECD signatory countries has also declined in recent years. The enforcement gap is creating unfair competition—companies from countries with lax enforcement will gain a de facto competitive advantage in corrupt markets.

For policymakers: Don’t just sign, enforce

The policy implications of the research are profound. For home-country governments, signing an international anti-corruption convention is only the first step. True governance capacity is reflected in sustained and effective enforcement. Only by making violating companies truly feel the pain can integrity be embedded in global value chains. At the same time, if host countries wish to attract “high-quality” foreign investment, the fundamental path remains reforming institutions and shrinking the space for corruption. This is not only a moral choice but also a competitiveness choice—research shows that investors from countries with sound institutions are more willing to invest in countries with clean governance.

For transnational organizations, such as the OECD and the United Nations, efforts should be made to harmonize anti-corruption enforcement standards and avoid “regulatory arbitrage” caused by differences in enforcement. Expanding the coverage of the Anti-Bribery Convention to emerging economies and strengthening information sharing and collaboration among national enforcement agencies are the foundations for building a fair global market.

For corporate executives: Compliance is the moat of long-term competitiveness

The research also serves as a wake-up call for corporate management: learning to “adapt” in corrupt markets may bring orders and growth in the short term, but in the long run, such “capability” will become a legal and reputational liability. Conversely, building a “clean hands” learning system not only helps companies avoid legal risks but also earns trust from stakeholders—including investors, customers, and host-country governments.

In an era of rising artificial intelligence and ESG governance, corporate integrity is being repriced by capital markets. Anti-corruption compliance is not just a gatekeeper duty but a core component of corporate strategy. Multinational companies need to realize that under the dual pressures of globalization retreat and regulatory tightening, only by embedding moral rationality into business logic can they gain long-term competitiveness in an uncertain world.

Corruption is not a distant moral issue; it is a global business training exercise that happens every day. And whether this training teaches companies the wisdom to stay clean or the skill to go along with corruption depends to a large extent on whether a country’s rule-of-law arteries are strong and vigorous.（Reference source: Dedho, N.H., Belderbos, R. & Cuervo-Cazurra, A.
