State Ownership and the Formal-Oversight Paradox: Audit-Committee Adoption and Disclosure Enforcement

This study of Vietnamese listed firms (2020–2024) finds that while higher state ownership correlates with fewer disclosure violations, the adoption of formal audit committees does not significantly alter this relationship, suggesting that state-linked firms rely on alternative institutional monitoring configurations rather than standard board-centered oversight to ensure accountability.

Imagine the world of big business as a giant, bustling school. In this school, the students are the companies, and the teachers are the people who own them. Usually, we think of the "teachers" (owners) and the "student council" (the board of directors) as two separate groups watching over the school to make sure no one is violating rules or mismanaging resources. One of the most popular ways schools try to stop violations is by creating a special "Honor Committee" (an audit committee) made up of strict, independent monitors who check the grades and the lunchbox logs.

But here's the tricky part: sometimes, the "teacher" isn't just a regular person; sometimes, the teacher is the School District itself (the State). When the State owns a big chunk of the school, things get complicated. The State isn't just a teacher; it's also the principal, the policy-maker, and the one who writes the rules. This paper asks a fascinating question: If the State is already watching the school, does the school still need to build that fancy new "Honor Committee"? And if they don't build it, does that mean they are violating rules more? The answer turns out to be a bit of a mystery that flips our usual expectations upside down.

The Great "Honor Committee" Mystery

This study, set in Vietnam, looks at a group of 467 companies (think of them as 467 different school clubs) between the years 2020 and 2024. During this time, the country passed a new rule saying that public companies should have a formal "Honor Committee" (an audit committee) to keep an eye on their financial reports. The researchers wanted to see who actually built these committees and what happened to the number of rule-breaking incidents (like misreporting money) that the government caught.

The Big Surprise: The "Do-Nothing" Paradox
The researchers found a strange pattern, which they call the "Formal-Oversight Paradox." Here is the weird part:

Less Building: Companies with the State as a major owner were less likely to build the new "Honor Committee." In fact, among the companies that didn't have one in 2020, only about 5.5% of the State-owned ones added one by 2024. Compare that to 14.3% of the non-State companies, which were much more eager to build these committees.
Less Violations Caught: Even though the State-owned companies were building fewer committees, they actually got caught breaking the rules less often. When the researchers looked at the data, they found that for every 10 percentage points increase in State ownership, the companies had about 21% fewer recorded violations the next year.

It's like walking into a classroom where the State is the teacher. You might expect that if the teacher is watching, the students would still need a strict student council to keep order. But instead, the students with the State teacher rarely formed a student council, yet they were the ones getting caught violating rules the least.

What It's NOT About

The authors are very careful to tell us what this study is not saying. They explicitly rule out a few simple ideas:

It's not that the committees are useless. The study doesn't say that having an Honor Committee is a bad idea or that it doesn't work.
It's not that State owners are "magic." They aren't claiming that State ownership automatically makes a company perfect.
It's not a simple cause-and-effect. The study does not prove that if you magically increased a company's State ownership, it would suddenly stop breaking rules. In fact, when they looked very closely at just two companies that actually changed their State ownership levels, the results were shaky and didn't support a simple "more State = less rule-breaking" story. The main finding is about how different types of companies organize themselves, not about what happens if you force a change.

The Real Story: Different Tools for Different Jobs

So, if the State-owned companies aren't building the committees but are still behaving well, what's going on? The authors suggest that these companies are using a different "toolkit" for monitoring.

Think of it like this: A regular company might rely on a shiny, new, high-tech security camera system (the Audit Committee) to catch thieves. But a State-owned company might rely on a different kind of security: a team of security guards who report directly to the principal, a strict set of internal rules, and regular inspections from the school district. They have a whole "bundle" of monitoring tools that work together.

The study found that among the State-owned companies that did have an Honor Committee, the committees weren't necessarily weaker. They didn't have fewer members, they didn't meet less often, and they weren't less independent. The State-owned companies just seemed to rely less on the existence of the committee as their main way of staying honest. They had other ways of keeping things in check that the researchers couldn't see in the data.

How Sure Are We?

The researchers are quite confident about the pattern they see: State-owned companies build fewer committees but get caught less often. However, they are very honest about the limits of their proof. They admit that because State ownership rarely changes (companies don't suddenly swap from private to State-owned every year), it's hard to say for sure why this happens.

They tried to look for the "smoking gun" by seeing if changing the State ownership caused a change in behavior, but they only found two companies that actually changed their ownership status enough to study. Because the evidence for that specific "cause-and-effect" is so thin, they don't claim to have solved the whole mystery. Instead, they suggest that we need to stop looking at one single rule (like "must have a committee") as the only sign of a good company. Sometimes, the best way to keep a company honest is a mix of tools that looks different depending on who owns the place.

In short, the paper teaches us that just because a company doesn't have the "standard" security camera doesn't mean they aren't being watched. Sometimes, the watchmen are just standing in a different spot.

Technical Summary: State Ownership and the Formal-Oversight Paradox

Problem and Motivation
Corporate governance research frequently models ownership structure, board composition, and audit committees as independent monitoring mechanisms. This simplification risks obscuring how governance is practically assembled, particularly in emerging markets where state ownership creates a complex interplay of roles (owner, appointing principal, policy actor). The central problem addressed is whether state ownership improves compliance through formal board-centered mechanisms or if firms rely on alternative institutional configurations. Specifically, the study investigates a counterintuitive empirical pattern in Vietnam: state-linked firms are less likely to adopt the newly formalized board-centered audit committee architecture, yet they record fewer regulator-sanctioned disclosure violations. The paper challenges the assumption that formal board oversight is a universal scalar measure of monitoring strength and questions whether a simple mediation model (state ownership $\rightarrow$ audit committee capacity $\rightarrow$ compliance) explains this relationship.

Methodology and Research Design
The study utilizes a panel of 2,335 firm-year observations from 467 nonfinancial companies listed on the Ho Chi Minh Stock Exchange (HOSE) and the Hanoi Stock Exchange (HNX) during the 2020–2024 period, following the Law on Enterprises 2020. The data requirements include consistent governance, ownership, financial, audit, and enforcement records.

The research design employs a strict temporal ordering, linking variables measured at $t-1$ to governance decisions at $t$ and enforcement outcomes at $t+1$ . The analysis is structured around four distinct components:

Extensive Margin (Adoption): A baseline cumulative logit and discrete-time complementary-log-log hazard model estimate the probability of first-time audit-committee adoption among 415 firms without a validated committee in 2020.
Intensive Margin (Architecture): Among firms with existing committees (304 observations from 96 firms), Poisson pseudo-maximum likelihood (PPML) and logit models test whether state ownership predicts substantive committee attributes (size, meeting frequency, independence, expert leadership, chair experience, legal expertise).
Enforcement Outcomes: PPML models estimate the association between lagged state ownership and the subsequent annual count of regulator-recorded disclosure violations (FDV), controlling for prior violations and firm characteristics.
Mechanism Falsification: The study sequentially conditions the enforcement model on audit-committee existence and architecture to test if these variables attenuate the state-ownership coefficient.

To address endogeneity and identify the source of variation, the authors employ Correlated Random Effects (CRE/Mundlak) decompositions and Conditional Poisson Fixed Effects models. Crucially, the study explicitly audits the "support" for within-firm variation, noting that state ownership is highly persistent.

Key Results

Adoption Gap (Extensive Margin): State-linked firms are significantly less likely to adopt an audit committee. Adjusted cumulative adoption is 5.5% for state-linked firms versus 14.3% for non-state firms. In the fully adjusted baseline logit, the state-linkage indicator (STATE_LINK) has an odds ratio of 0.300 for adoption. In contrast, the continuous state ownership variable shows a weaker association, where a ten-percentage-point increase yields an odds ratio of 0.837.
Architecture (Intensive Margin): Among firms that already have committees, state ownership does not systematically predict weaker committee design. There is no broad evidence that state-linked firms operate smaller, less independent, or less expert committees. A persistent positive level association exists with chair experience, but no significant annual reconfiguration is observed.
Enforcement Gradient: Higher state ownership is associated with fewer subsequent recorded violations. A ten-percentage-point increase in state share corresponds to an incidence-rate ratio (IRR) of 0.786, implying approximately 21.4% fewer expected violations.
Mechanism Failure: Conditioning the enforcement model on audit-committee existence and all observed architectural features results in negligible attenuation of the state-ownership coefficient (IRR shifts from 0.786 to 0.793). This rejects the hypothesis that observed committee capacity is the primary channel linking state ownership to lower enforcement.
Identification Boundaries: While pooled and between-firm estimates show a negative association between state ownership and violations, within-firm estimates (CRE and Fixed Effects) reverse the sign. However, the authors note that this within-firm variation is supported by only two firms that change state share and contribute outcome information. Consequently, the within-firm estimates are treated as adverse diagnostics rather than causal treatment effects.

Significance and Claims
The paper claims to identify a "formal-oversight paradox": the coexistence of lower entry into a formal board-centered architecture and fewer recorded enforcement events among state-linked firms. The study does not claim that state ownership is intrinsically superior or that audit committees are ineffective. Instead, it argues for a bounded governance-regime interpretation.

The findings suggest that state ownership marks a persistent institutional regime where monitoring is allocated across different channels (e.g., ownership representation, administrative accountability, internal control) rather than being concentrated in the board-centered audit committee. The study contributes by:

Shifting the debate from a directional "good vs. bad" ownership narrative to a governance architecture perspective.
Separating the extensive margin of governance formalization from the intensive margin of committee design.
Demonstrating that observed audit-committee architecture does not explain the state-ownership gradient in enforcement.
Explicitly delineating the limits of causal inference in governance research where ownership is persistent and within-firm variation is sparse.

The paper concludes that formal board oversight and recorded enforcement can move differently when monitoring is organized through alternative institutional configurations, cautioning against treating audit-committee presence as a universal proxy for monitoring strength in state-capital contexts.
