Financing Costs, Credit and Capital Formation in Albania: Integrated Reconstruction after Three Tests of the i-I Model
This paper employs an ARDL/UECM model on Albanian quarterly data from 2006 to 2025 to demonstrate that while financing costs significantly negatively impact capital formation, the credit channel reflects leverage and balance sheet stress rather than pure funding availability, highlighting the complexities of monetary transmission in a bank-based, euroized economy.

Imagine Albania's economy as a bustling, slightly chaotic construction site. The goal? To build more houses, factories, and roads (what economists call gross fixed capital formation). For years, people wondered: what actually makes the cranes start moving? Is it just having a lot of money in the bank, or is it how expensive it is to borrow that money?
Admir Mulaj, the author of this paper, decided to play detective with data from 2006Q4 to 2025Q4. He didn't just look at the construction site; he looked at the bank loans, the interest rates, and the currency mix (a unique situation where Albanian businesses use both the local Lek and the Euro).
Here is what the investigation found, using some simple analogies.
The Price Tag on Money (The Cost of Capital)
The strongest clue the paper found is about the price tag. Imagine you want to buy a new video game. If the price goes up, you probably won't buy it, right? The paper found that when the "spread" (the extra cost banks charge on top of the basic rate) goes up, investment in Albania goes down.
This confirms a classic idea: when borrowing money gets more expensive, companies hesitate to start new projects. The paper shows this relationship clearly in both the local Lek currency and the Euro currency. It's like a thermostat: when the cost of heat (money) rises, the furnace (investment) turns down.
The "Credit" Trap (A Nuanced Warning)
Here is where it gets tricky, and where the paper offers a crucial warning against a common misunderstanding.
Many people think: "If the bank lends more money, the economy must be growing!" The paper says: Not so fast.
When the researchers looked at the ratio of total credit to the size of the economy (Credit-to-GDP), they found something surprising. Sometimes, when this ratio goes up, investment doesn't necessarily follow a simple upward path. The paper argues that a high credit number doesn't always mean "new money for new factories."
Instead, think of it like a credit card bill. If your income drops but you keep charging groceries to your card, your credit balance goes up, but you aren't buying a new house. In Albania, a high credit-to-GDP ratio often signals that companies are struggling to pay their bills, are piling up debt to stay afloat, or that the economy (the denominator) is shrinking faster than the debt. The paper suggests we should be very careful not to treat a high credit number as a simple "green light" for growth; sometimes, it's actually a signal of leverage or balance sheet stress. It doesn't mean credit causes investment to fall, but rather that high credit ratios can be a sign of financial pressure rather than pure productive expansion.
The Missing Puzzle Pieces (The Financial Accelerator)
There is a famous theory called the "Financial Accelerator." It suggests that when a company's balance sheet gets shaky, banks get scared, stop lending, and the whole economy crashes faster than expected.
The paper suggests this might be happening in Albania, but it cannot prove it. Why? Because the data is like a puzzle with missing pieces. The researchers have the big picture (interest rates, total loans), but they are missing the specific details: they don't have a clear list of exactly which companies have shaky balance sheets, what collateral they are using, or how much bad debt the banks are holding.
So, while the evidence points toward this theory, the paper stops short of saying, "We have solved the mystery." It's more like saying, "The clues fit the theory, but we need more evidence to be 100% sure."
The Euro vs. Lek Mix-Up
Albania is a special case because it's "partially euroized." This means some loans are in Euros and some are in Lek. The paper had to be very careful with its math. It found that mixing a Euro loan rate with a Lek bond rate creates a "diagnostic" number that is a bit messy—like trying to measure a room using both feet and meters at the same time.
To get a clean answer, the researchers focused on comparing "apples to apples": Euro loans vs. Euro rates, and Lek loans vs. Lek rates. When they did this, the "cost of money" rule held up perfectly: higher costs mean less building.
The Bottom Line
The paper concludes that in Albania, investment is sensitive to the cost of borrowing. If the price of credit goes up, building slows down. However, simply seeing more loans in the system doesn't automatically mean the economy is booming; it might just mean companies are dealing with debt stress or a shrinking economy.
The authors don't claim to have found a magic formula that solves Albania's economic problems. Instead, they built a reliable map that shows us where the road is smooth and where the potholes (like currency mix-ups and debt stress) are hiding. They suggest that policymakers need to look beyond just the interest rate and pay attention to who is borrowing, what currency they are using, and why they need the money.
In short: Money is the fuel, but if the fuel is too expensive or if the tank is leaking with old debt, the engine won't run fast, no matter how much you try to pour in.
