When we hear about globalization, we often imagine giant corporations shipping products across oceans, negotiating trade deals, and chasing the lowest costs. But a quieter story is unfolding behind the scenes—one about the life journeys of individual firms.
Some companies begin selling to the world almost as soon as they are born. Others spend years focused on their home market before daring to export. It turns out that this difference—when a firm starts exporting—can influence not only its own success, but also how quickly an entire country benefits from trade.
My job market paper using detailed data from India suggests that so-called “born-global” firms play an outsized role in driving trade growth. Their presence (or absence) can even affect how quickly a country gains from lowering trade barriers. The findings challenge some traditional economic ideas about trade and offer a fresh perspective on how globalization really works.
The Myth of the “Typical Exporter”
For decades, economic thinking treated exporters in a fairly simple way. The story went like this: more productive firms export, less productive ones don’t (Melitz, 2003). Over time, successful exporters expand abroad, and trade grows (Ruhl and Willis, 2017).
But reality is messier. Firms are not just more or less productive. They are also young or old, and these differences matter. Looking at Indian manufacturing firms over more than 30 years, a new study noticed a striking pattern. Firms that start exporting soon after they are founded behave very differently from firms that wait many years before entering foreign markets. The early movers -call them born-global firms- tend to:
- Export a large share of their sales right from the start
- Maintain strong export performance over time
- Survive longer in foreign markets
Late starters, by contrast, usually:
- Begin with small export volumes
- Expand slowly, if they survive
- Exit export markets more often
For example, Figure 1 plots the first ten years of export growth for firms starting export at age 2 versus age 10, as an example of young and old firms. The difference is hard to miss.

In short, exporting early is not just about timing—it reflects a different kind of firm.
If you’ve ever met a startup founder who dreams internationally from day one, this idea may feel familiar. Some entrepreneurs design their companies for global markets from the start. They may hire managers with foreign experience, build products for international standards, or develop overseas contacts early.
These globally minded firms are not rare exceptions. They account for a meaningful share of export growth. Many of the firms driving new exports are those that entered foreign markets early in their lives.
This raises an important question: why do some firms go global early while others don’t?
The Hidden Investment Behind Exporting
Exporting is not as simple as putting goods on a ship. Firms often need to:
- Learn foreign regulations
- Build distribution networks
- Adapt products to local tastes
- Manage logistics and currency risks
All of this takes effort and money.
One way to think about it is that firms can make an early investment in being good at exporting. Some build capabilities that lower the ongoing costs of selling abroad—better logistics, stronger networks, or export-friendly management.
Some startups are especially willing to make these investments. They are still shaping their identity and strategy. If they aim for global markets from the start, they can build their operations around that goal.
Older firms, in contrast, may be deeply rooted in domestic markets. Shifting toward exports later can be costly and risky. They may try exporting, but often on a smaller scale.
This helps explain why early exporters look stronger: they prepared for it.
Why This Matters for Entire Economies
At first glance, this might sound like a business story. But it has big economic implications.
When countries lower tariffs or sign trade agreements, policymakers often expect trade to rise quickly. More trade should mean lower prices, more variety, and higher living standards.
But in practice, trade often grows slowly after liberalization. One reason, the evidence suggests, is that it takes time for the right kinds of firms to emerge.
Trade growth depends not just on prices, but on who the firms are. If young, globally oriented firms are entering and thriving, trade can expand strongly. If fewer such firms appear, growth is slower.
In other words, trade is shaped by the “demographics” of firms—the mix of young and old, export-ready and domestically focused companies.
The Long Wait for Trade Gains
One surprising finding is how long trade adjustment can take.
After a country reduces tariffs, total trade may keep rising for decades. Why? Because the population of firms is constantly changing. New firms enter, some invest in export capabilities, others don’t. Over time, the share of strong exporters evolves.
If fewer young firms enter in the short run, there are fewer born-global exporters to drive trade.
That can slow overall trade growth, even if tariffs are low.
This also affects how people experience the benefits of globalization. The long-run gains can be substantial, but the short-run gains may be smaller than expected.
Rethinking Trade Policy
These insights suggest that trade policy is not just about cutting tariffs. It is also about creating an environment where young firms can thrive globally.
Policies that may help include:
- Easier access to financing for startups
- Information and support for entering foreign markets
- Infrastructure that reduces shipping and logistics costs
- Education and training with an international focus
Encouraging globally minded young firms could amplify the benefits of trade liberalization.
This doesn’t mean older firms are unimportant. Many succeed abroad. But the evidence suggests that early exporters punch above their weight in shaping national trade outcomes.
The Big Takeaway
The new evidence points to a simple but powerful idea: When firms go global matters.
Companies that export early tend to export more, survive longer, and drive a meaningful share of trade growth. Because these firms shape how trade expands, they also influence how quickly countries benefit from globalization.
Global trade is often portrayed as a battle among giants. But sometimes, the smallest and youngest players help decide how the story unfolds.
