Start-up certification and prices: Evidence from markups and a statutory expiry in Italy
This paper analyzes Italian data to conclude that while certified innovative start-ups initially exhibit lower markups than ordinary SMEs, this difference is driven by the selection of inherently more efficient firms rather than the certification status itself, as the loss of certification due to statutory expiry has no causal effect on pricing.

In the world of business, a company's success is often measured by how much money it keeps after paying its bills. Economists call this the "markup," the difference between what a firm charges for its product and what it costs to make it. This gap is more than just a number on a spreadsheet; it reveals whether a business is powerful enough to set high prices or if it is simply operating efficiently. Governments often try to help new, innovative companies grow by giving them special perks, such as tax breaks, easier access to loans, and exemptions from certain fees. The logic is that by lowering the costs for these young firms, the government helps them survive and compete. However, a critical question remains: does this help actually change the prices these companies charge their customers? If a government lowers a company's costs, does that saving get passed on to the buyer in the form of a lower price, or does the company keep the saving as extra profit?
A team of researchers in Italy set out to answer this question by looking at a specific government program designed for innovative start-ups. Italy has a law that grants special status to new, innovative companies, giving them a bundle of financial benefits. This status is not permanent; it automatically expires exactly five years after a company is founded. This fixed deadline creates a unique natural experiment. Because the end of the benefits is set by law rather than by the company's own choices, researchers can observe what happens to a company's pricing the moment the support disappears. By studying thousands of company records over nearly a decade, the researchers could see if the removal of these government perks caused prices to jump up, drop down, or stay exactly the same.
The study focused on a massive dataset of over 76,000 yearly records from nearly 12,000 Italian companies. The researchers compared three groups: companies that held the special innovative start-up status, those that had graduated to a slightly less exclusive "innovative small business" status, and ordinary small businesses that never received any special treatment. They calculated the markup for each company by analyzing their financial statements, looking at how much revenue they made compared to the cost of the materials and services they bought. The first thing they found was that the companies with the special status did indeed charge lower prices than ordinary businesses. However, this difference was not because the government program changed how those companies priced their goods. Instead, the lower prices were a sign of who applied for the program in the first place. The companies that registered were already smaller, younger, and spent a larger portion of their sales on buying materials from others. The government label simply identified a group of firms that already operated differently, rather than transforming them.
The most revealing part of the research came when the companies hit their five-year deadline and lost their special status. If the government benefits had been keeping prices low by reducing costs, one would expect prices to rise once those benefits vanished. Conversely, if the label had signaled high quality to customers, losing it might have forced prices down. The data showed neither of these things happened. On average, when a company lost its start-up status, its pricing did not change at all. The researchers used a specific legal extension granted in 2020, which pushed the deadline back by one year for some groups, to confirm that this lack of change was not just a coincidence of timing. Even when they looked closely at the moment the status expired, the companies' markups remained flat. This suggests that the government support was not being used to manipulate prices or to create extra profit margins that would disappear without the state's help.
However, the story is not entirely uniform. When the researchers grouped the companies based on how they actually operated—distinguishing between those that relied heavily on machinery and raw materials and those that relied mostly on human talent and development—they found a hidden pattern. For companies that were heavy users of fixed assets and materials, losing the special status did cause their markups to drop slightly, by about five to six percent. For other types of companies, the change had no effect. This indicates that the government benefits did lower costs for some specific kinds of businesses, but for the average company, the removal of the status had no measurable impact on the price they charged. The overall result was a mix of small drops and no changes that canceled each other out, leading to the appearance of no effect at all.
The researchers also tested their findings using advanced computer methods to ensure they had not missed any complex patterns. They used machine learning tools to check if the simple mathematical models they used were missing something important. These tools confirmed that the main conclusion was correct: the government label did not fundamentally change how companies set their prices. The tools did show that a company's internal structure, such as how much it spent on staff versus materials, explained a lot of the variation in pricing, but the government status itself was not the driver. The study concludes that the Italian program successfully identified young, input-intensive firms and helped them with financing and survival, but it did not alter the margin they earned on their sales. The benefits were absorbed in ways that did not show up in the final price tag, proving that a public label attached to a company, unlike a label attached to a product, carries very little power to change what that company charges.
