Micro-Heuristics, Macro-Strategy: An Agent-Based Model of Contingent Build, Partner, and Acquire Choice in Legacy-to-Emerging Market Transitions
This paper employs an agent-based model to demonstrate how boundedly rational firms transitioning from declining legacy markets to emerging ones make contingent build, partner, or acquire decisions based on feasibility and cost, revealing that while acquisition often yields the most market leaders, early entry provides a persistent advantage and the optimal sourcing strategy varies significantly depending on specific cost structures and firm scale.

In the business world, companies often face a moment of reckoning when their old, reliable way of doing things begins to fade, while a new, exciting opportunity rises to take its place. Think of a film studio watching digital cameras replace celluloid, or a car manufacturer seeing electric vehicles overtake the internal combustion engine. The challenge is not just noticing that the world is changing, but deciding how to cross over into the new one. A company can try to build the new technology from scratch inside its own walls, it can team up with another firm that already has the skills, or it can buy a company that has mastered the new way. There is also the option to wait and see. This decision is rarely simple because the path a company takes depends on what its rivals are doing, how much money it has, and how fast the new technology is moving. If a company chooses the wrong path, or chooses it too late, it may fail even if it saw the change coming.
Researchers have long studied how firms adapt, but they have often looked at these choices as isolated events or static snapshots. A new study by Yingzheng Liu and colleagues takes a different approach. Instead of looking at a single company or a single year, they built a computer simulation that acts like a digital laboratory for an entire industry. In this virtual world, hundreds of different companies, each with its own strengths and weaknesses, make decisions year after year as a market shifts from an old, declining state to a new, growing one. The researchers programmed these digital firms to be realistic: they are not perfect calculators that always make the best choice, but rather boundedly rational actors who follow routines, react to their own performance, and learn from their mistakes. By running this simulation thousands of times, the team could watch how individual choices added up to shape the entire market, revealing patterns that are hard to see in real-world history.
The study found that the most common path a company takes is often not a matter of preference, but of availability. When a company decides to buy a competitor to get new skills, that competitor is removed from the market and is no longer available for anyone else to buy. This means that the choices made by early movers physically change the menu of options for those who come later. In the simulation, the mix of strategies used by companies shifted not because firms suddenly changed their minds about what they wanted, but because the targets they wanted to buy or the partners they wanted to join were already taken. This creates a situation where the most successful strategy depends heavily on timing and on what resources are left in the pool.
One of the most striking findings concerns the value of being first. The simulation confirmed that companies that enter the new market early do gain an advantage, but this advantage is not a magical shield. It is a "time-in-market" effect, meaning that the longer a company is present in the new environment, the more it learns and the stronger it becomes. However, this advantage is fragile and conditional. The erosion of the early-mover lead as the pace of change speeds up only occurs when the simulation includes specific channels that allow followers to catch up through imitation and that cause early leads to become obsolete. When these channels are active, the gap between early and late entrants shrinks at the fastest paces. But when these channels are turned off, or when the timing of entry is randomized, the early advantage remains positive and does not erode, suggesting that the fragility of the lead depends on specific mechanisms of learning and obsolescence rather than on the speed of change alone.
The study also clarified which strategy leads to the best long-term survival for the companies that enter. When looking at the companies that successfully entered the new market, those that started by buying an existing firm were the most likely to end up as leaders or survivors. This is because buying a company gives an immediate, fully formed operation with its own customers and capabilities. In contrast, building a new unit from scratch takes time to ramp up, and during that slow start, it is more vulnerable to failing. Partnering with another firm sits in the middle; it offers flexibility but requires constant coordination. Interestingly, the researchers found that if a company builds its new unit at a larger scale from the very beginning, the advantage of buying a company disappears, and partnering can become the better path. This suggests that the "best" choice is not fixed; it changes depending on how much capacity a company can bring to the table and how much it can afford to invest upfront.
The researchers also discovered that the market naturally tends to concentrate around a few dominant players, a process known as a shakeout. In the simulation, as the new market matured, a few companies pulled ahead while many smaller ones fell away. This happened because the market rewards the strongest performers with more customers, creating a cycle where the leaders get stronger and the laggards struggle to survive. The study showed that this concentration is not an accident of the simulation but a direct result of how demand is allocated to the most capable firms. When the researchers turned off the mechanism that rewards the leaders, the concentration disappeared, proving that this outcome is driven by the specific rules of competition they modeled.
Ultimately, the study paints a picture of a complex, dynamic system where no single strategy is perfect for every situation. The success of a company depends on a delicate balance between its own resources, the speed of the market, and the choices made by its rivals. While buying a company often provides the safest route to leadership in the simulations, this advantage can vanish if the cost of buying becomes too high or if the company can build its own capability at a large enough scale. The research suggests that managers should not look for a single, universal rule for how to respond to change. Instead, they must constantly assess what is available to them, how fast the ground is shifting beneath their feet, and whether their own resources allow them to take the path that is open. The study does not offer a crystal ball that predicts the future, but it provides a clear map of the forces that shape how industries evolve, helping leaders understand why some companies thrive while others fade away.
