Key points
- ① Until now, no credit history meant no loan. AI-based alternative credit scoring opens the door to credit for the financially excluded.
- ② This paper shows mathematically that the mere possibility of "getting credit in the future" leads people to consume more steadily today.
- ③ The benefit is largest for the households in the toughest circumstances: the social value of AI credit scoring.

To borrow from a bank you need a "credit history." But what about people with thin files, such as recent graduates starting their first job, owners who have just opened a shop, or long-time homemakers? Even if they can repay, the door closes because "there is no record."
AI-based alternative credit scoring has recently begun to open that door. Instead of banking records, it uses market-area, sales and other data to assess "whether this person can repay." It is the same kind of technology RenaAi uses to assess 3.16 million small businesses without a credit history.
So the fundamental question: if we open credit to people who were excluded, do their lives actually get better? This paper answers with "mathematics."
1The core idea: the "possibility" alone changes lives
The paper models a situation in which credit "may open up in the future, though no one knows when" (credit expansion opportunities that arrive at random). Remarkably, even before credit actually opens, the mere "possibility that it may open" changes how people behave today.
- They consume a little more, save less and invest a little more in risky assets (stocks).
- Why? Because they count the "credit capacity" they may be able to use in the future as part of today's resources.
2The most important finding: consumption becomes "smoother"
Economics has a concept called "consumption smoothing": keeping consumption as even as possible even when income is uneven. That makes life less precarious.
The paper shows that the greater the likelihood that credit will open in the future, the less a household's consumption is driven by "the money in its account right now" (technically, a lower marginal propensity to consume, MPC). In other words, even when balances swing, life is less squeezed.
3And the effect is larger for those in tougher circumstances
This is the most important part. The "stabilizing effect" is larger for households with fewer assets. For people who have little, the "capacity to borrow in the future" makes up a larger share of their total lifetime resources.
In other words, AI credit scoring does not only help financial institutions. It actually makes life more stable for people who have been excluded, and it helps most those who need help most. This is "Inclusive Household Finance."
4What does this have to do with RenaAi?
RenaAi's market-area alternative credit scoring (SBCR) assesses 3.16 million small businesses without credit histories using market-area data. It is a real-world implementation of the "AI-enabled credit assessment" this paper describes. The paper supports the "social value" of that technology in theory: the door to credit we open does more than provide loans; it makes people's lives more stable.
Wrapping up: opening the door to credit
A door that stayed shut because there was no credit history. When AI opens it, people do more than borrow money: they live more stable lives. And the benefit is greatest for those who struggle most. That is why RenaAi does alternative credit scoring.
"Opening the door to credit is not just about loans. It opens up lives."
