The Invisible Barriers: Why Investment Climate Reform Is Still the Hardest Work in Development

Behind every failed market entry and stalled investment decision is a tangle of invisible barriers, the informal rules, bureaucratic delays, and institutional asymmetries that no policy document ever fully captures. I have spent the better part of fifteen years trying to understand them, and I am still learning.

The visible barriers are easy to name. Tariffs. Licensing requirements. Foreign ownership ceilings. These appear in regulatory texts and, for as long as the index existed, showed up cleanly in the World Bank’s Doing Business data. Governments can commit to reducing them. Donors can fund technical assistance to streamline them. Progress is measurable, reportable, presentable at a donor coordination meeting.

The invisible barriers are different. They operate in the gap between what the law says and what an investor actually experiences when they try to register a business, secure a permit, or resolve a commercial dispute. They are felt rather than read. And they are, in my experience, the real reason that most investment climate reform programmes underdeliver.

What I Mean by Invisible

In 2019, I was supporting a regulatory reform process in one of Southern Africa’s more reformist economies. The government had, over two years, simplified its business registration process, reducing the number of steps from fourteen to six and cutting the official processing time from thirty days to five. On paper, it was a genuine achievement. The consultants had done their work. The legislation was amended. The data would confirm the improvement.

I visited the registration office unannounced. I watched. The five-day process was taking three weeks, not because of any rule, but because the staff responsible for step three had an informal arrangement with a local business services firm. Applicants who used this firm’s “facilitation services” moved through in four days. Everyone else waited.

The regulation had changed. The system had not. And the system was the thing that investors actually encountered.

This is what I mean by invisible. Not corruption in the grand sense, the kind that lands on front pages, but the low-level, normalised arrangements that persist inside formal institutions long after the formal rules have changed. They are invisible because they do not appear in any audit, any investor perception survey, or any ease-of-doing-business index. They are invisible because the people who maintain them are not malicious. They are simply operating within the incentive structure they inhabit.

Why Conventional Reform Misses Them

The standard investment climate reform toolkit was built to address the visible. It works on legislation, on procedures, on regulations. It counts the number of days to start a business, the number of procedures to register property, the cost of enforcing a contract. These are legitimate concerns. Reforming them creates real, measurable improvements.

But the toolkit was not designed for the gap between the rule and its implementation. It was not designed for the informal power structures that persist inside revenue authorities, customs agencies, and municipal offices. It was not designed for the trust deficit between investors and government institutions that has built up over decades of inconsistent enforcement and unpredictable policy change.

The result is a peculiar pattern I have observed across multiple reform programmes: substantial improvements in the formal indicators, minimal improvement in investor confidence. The World Bank’s Doing Business ranking went up. Foreign direct investment did not follow. Domestic private sector actors, who know the informal system intimately, continue to hedge, delay, and underinvest.

What Actually Works

I do not have a clean answer. If I did, investment climate reform would be easier than it is. But I have observed some patterns across the programmes that have made the most durable difference.

The first is granularity. Reforms that work tend to be deeply specific. Not “streamline business registration” but “redesign the workflow in the one-stop shop so that the revenue authority representative has visibility into applications at step two, not step five.” Generic reforms produce generic results. Targeted reforms, designed with knowledge of the actual informal processes at work, can shift incentives in ways that general interventions cannot.

The second is sustained political engagement at a very practical level. The kind of engagement I mean is not the high-level roundtable with the minister, though that has its place. I mean the consistent, painstaking work of building relationships with the mid-level civil servants who actually control how processes flow. These are the people who make decisions about sequencing, about which applications get priority, about who gets called when a file goes missing. Without their buy-in, reform is a change to the text of a regulation. With it, reform can be a change to how things actually work.

A reform that is not owned at the implementation level is not a reform. It is a document.

The third is honest monitoring. The investor perception surveys and formal indicators that dominate investment climate monitoring tell us something, but not the most important things. They tell us what investors think when surveyed, not what they experience when they try to do business. Rigorous qualitative monitoring, including mystery shopper exercises and detailed case tracking, gives a different picture. It is also harder to produce, harder to aggregate, and harder to present to a donor audience. Which is part of why it is rarely done systematically.

The Deeper Challenge

Underlying all of this is a structural tension at the heart of development assistance. The programmes designed to improve investment climates are usually funded on two- to four-year cycles. They are evaluated against indicators that can be measured within that timeframe. They are implemented by teams, often including highly capable consultants, who rotate in and out of the country and carry their institutional knowledge with them when they leave.

The informal systems that obstruct investment were built over decades. They will not be dismantled in a project cycle. The civil servant who has spent fifteen years learning which phone call to make and which favour to offer is not going to abandon that knowledge because a reform programme has produced a new set of procedures. The trust deficit between business and government that has accumulated across generations of broken promises is not going to be addressed by a revised licensing framework.

This does not mean the work is futile. The formal changes matter, because they create the conditions within which informal norms can eventually shift. But they matter on a timescale that investment climate reform programmes are rarely funded to work on.

I think the most honest thing we can say is this: investment climate reform is necessary but not sufficient, and the gap between what it can deliver and what it promises is largely invisible, which is why it persists. Making that gap visible, naming it clearly, and designing programmes with enough honesty to work on it, that is, I think, the most important work still to be done in this field.

The invisible barriers are real. They are resistant. And they deserve our full attention.
