Macroeconomic Adjustment under Inflation-Targeting and Non-Targeting Regimes: Evidence from African Economies
This paper utilizes panel econometric models on African data from 2000 to 2024 to demonstrate that inflation-targeting regimes foster greater macroeconomic stability and faster shock adjustment compared to non-targeting regimes, primarily due to enhanced policy credibility and anchored expectations.

Imagine the economy of a country as a giant, chaotic ship sailing through a stormy ocean. The waves are things like sudden price hikes, changes in how much money people earn, or shifts in the value of the country's money compared to others. The captain of this ship is the government's monetary policy. For decades, economists have debated the best way to steer this ship. One popular theory is "Inflation Targeting." Think of this as the captain having a very specific, public promise: "I will keep the ship's speed (prices) steady at exactly 10 knots." By making this promise loud and clear, the crew (the public and businesses) trusts the captain, so they don't panic when a wave hits. They know the captain will fix it.
The other approach is "Non-Targeting." Here, the captain doesn't make a specific promise about speed. Instead, they might just try to steer by looking at the wind, the waves, or the fuel gauge, changing direction whenever they feel like it. This can make the crew nervous because they never know what the captain will do next. If the crew gets scared, they might start running around, which makes the ship wobble even more. This paper asks a simple but crucial question: When a storm hits, which captain gets the ship back on a smooth path faster? Does the captain with the clear promise (Inflation Targeting) handle the bumps better than the one without a plan (Non-Targeting)? This matters because if a country's economy is too wobbly, prices go crazy, jobs disappear, and life becomes hard for everyone on board.
This paper dives into the history of six African nations to see how their "ships" handled the storms between the years 2000 and 2024. The researchers split these countries into two groups: the "Inflation-Targeting" (IT) crew, which includes South Africa, Ghana, and Uganda, and the "Non-Targeting" (NIT) crew, which includes Egypt, Nigeria, and Ethiopia. Using complex mathematical tools called Panel Vector Error Correction Models and Panel Vector Autoregressions (think of them as high-tech weather radars that track how different parts of the economy talk to each other), the author watched how these economies reacted when things went wrong.
The findings are pretty clear, like a lighthouse beam cutting through fog. The countries with the "Inflation Targeting" promise showed much better stability. When a shock hit—like a sudden spike in prices—these economies bounced back to their normal state much faster. Their inflation didn't stay high for long; it was like a temporary splash of water that dried up quickly. Also, their growth and exchange rates (how much their money is worth compared to others) didn't get as shaken up by these price shocks. The author suggests this happens because the public trusts the captain, so they don't overreact, which keeps the whole ship steadier.
In contrast, the Non-Targeting countries had a much rougher ride. When a shock hit, their economies took a long time to settle down. Their inflation was more volatile, swinging wildly like a pendulum. The paper finds that in these countries, a shock to prices often led to a bigger, more lasting mess in other areas, like the value of their currency or their government's budget. It's as if the Non-Targeting captains were reacting to every wave with a sudden, sharp turn, causing the ship to roll dangerously. The study suggests that in these places, the link between the exchange rate and prices was much stronger and more damaging; if the currency dipped, prices shot up immediately and stayed there.
One of the most interesting things the paper found is about how long these shocks lasted. In the Inflation-Targeting countries, the author found that price shocks were mostly "transitory," meaning they were short-lived and didn't stick around to cause long-term damage. However, in the Non-Targeting countries, these shocks were "persistent," meaning they lingered and kept the economy unstable for a longer time. The paper also notes that in the Non-Targeting group, the government's budget (fiscal balance) played a bigger role in causing inflation, suggesting that when the government spends too much, it creates a bigger mess if there isn't a strong, trusted monetary policy to hold things together.
The author is careful to say that this isn't a magic wand. Having an Inflation Targeting regime doesn't automatically fix everything. The paper suggests that for this system to work, you need other things in place, like a government that doesn't spend more than it earns and a central bank that is truly independent. Without those supporting pillars, even a clear promise might not be enough to keep the ship steady. But overall, the evidence points to the idea that having a clear, trusted plan for keeping prices stable helps African economies recover from storms much faster and with less chaos than those without such a plan.
