State Capacity and the Price of Risk: Cross-Country Evidence on Institutions and the Cost of Credit
This paper finds that while higher state capacity is associated with lower private credit spreads, this relationship is primarily mediated by increased financial depth and income rather than acting as a direct, independent price signal.

Imagine the global economy as a massive, bustling marketplace where countries are like different neighborhoods. In some neighborhoods, the streets are well-lit, the police are reliable, and contracts are honored without a second thought. In others, the rules change overnight, corruption is rampant, and no one knows who is in charge. Just like you would pay a higher price for a house in a risky neighborhood, banks charge higher interest rates to lend money to countries with shaky rules. This field of study, called economics, tries to figure out exactly why some places are "expensive" to borrow from and others are "cheap." The big question isn't just whether good rules make things cheaper, but how they do it. Does a strong government directly tell banks, "Hey, you can trust us, so charge less," or does a strong government simply build a richer, deeper economy, and that richness is what actually lowers the price? It's the difference between a coach yelling "Play better!" and a coach actually training the team until they are so skilled that winning becomes easy.
This paper, titled "State Capacity and the Price of Risk," dives into that exact mystery using data from nearly 200 countries over almost three decades. The authors treat "state capacity" like a country's overall muscle memory for getting things done—how well it enforces laws, keeps corruption in check, and stays politically stable. They look at the "price of risk," which is basically the extra fee banks charge to lend money in a country compared to a safe, risk-free bet. By crunching numbers from the World Bank, they act like detectives trying to separate the signal from the noise. They want to know: if a country improves its government today, does the cost of borrowing drop tomorrow because the government is better, or is it just because the country got richer and the banks got more confident?
The investigation reveals a story that is both encouraging and a little humbling. When the authors looked at how countries changed over time—like watching a single neighborhood improve its streetlights and police force—they found a clear, real connection. When a country's "muscle memory" for good governance improved by one standard step, the interest rate banks charged dropped by about 2.0 to 2.6 percentage points. That's a significant discount, like getting a massive coupon on a loan. They tested this by looking at how a country's governance from 25 years ago predicted its current borrowing costs, and the result held up, suggesting that better rules do indeed make lending safer and cheaper.
However, the plot thickens when they looked at the big picture across all countries at once. They discovered that this "good government discount" isn't a magic spell that works in isolation. Instead, good governance acts like a master key that unlocks two other doors: it helps the country get richer (higher income) and it helps the banking system grow deeper and more robust. Once the authors accounted for these two factors—wealth and deep financial markets—the direct "discount" for having good government vanished. It turns out that good governance doesn't lower the price of credit by waving a magic wand; it lowers the price by building a richer, more sophisticated economy that naturally attracts cheaper money.
The paper also zooms in to see which specific parts of "good governance" matter most. It's not just about fighting corruption or making sure the government is efficient; the data suggests that lenders care most about the Rule of Law (contracts being honored), Regulatory Quality (rules being clear and fair), and Political Stability (no sudden coups or chaos). These three seem to be the heavy lifters that drive the lower interest rates.
In the end, the authors conclude that while improving your government is a real and powerful way to lower borrowing costs, you can't expect it to work in a vacuum. It's not a direct line from "better laws" to "cheaper loans." Instead, better laws build a stronger, wealthier economy, and that is what ultimately convinces banks to lower their prices. So, if a country wants to make borrowing cheaper, it shouldn't just try to tweak a single rule; it needs to build the whole foundation of a stable, wealthy, and deep financial system. The evidence is strong that the path exists, but it runs through the economy, not just the government office.
