The Synergy Trap: Why Interconnected Tech Often Launches Half-Baked

We usually assume that when companies build complementary products—like electric vehicles and charging networks, or hardware platforms and specialized software—the natural synergies align their incentives and create a win-win for everyone. But what happens when independent firms are developing these interconnected ecosystems over time? In my new paper “Selling Synergies,” I formally explores this dynamic by modeling two profit-maximizing sellers developing complementary products. Each firm continuously invests in product development and decides exactly when to stop refining, launch to the market, and set a price for consumers who exhibit a synergy benefit from owning both items.

The analysis reveals an interesting mechanism that turns these positive synergies into a source of inefficiency: the firm that launches first (the “leader”) has a strong incentive to strategically underinvest in their own product. By halting development early and launching a lower-quality product with an exclusionary, high price, the leader forces the second firm (the “follower”) into a corner. The follower is nudged to target the broader mass market and must continue developing their product to a high standard. This allows the leader to essentially free-ride on the follower’s hard work, extracting a lucrative “synergy premium” from early, high-paying buyers without putting in the development time themselves.

Because securing this leader position is so incredibly profitable—yielding more than a standard standalone monopoly would—a destructive “preemption race” kicks off. Both firms aim to capture the first-mover synergy premium that they try to undercut each other’s launch dates. Ultimately, this intense competition completely unwinds the very premium they were chasing. The race only stops when synergy rents profits are totally dissipated, resulting in companies rushing underdeveloped products to the market long before they are actually ready. Crucially, note that this rush to the market is not driven by an arms race between competitors who try to beat each other to the punch, but rather by an urge to dominate a fledgling ecosystem.

The results challenge standard economic and regulatory playbooks. While we intuitively expect product synergies to enhance overall value, this uncoordinated race actually destroys product quality and reduces overall market welfare. Government interventions like standard R&D subsidies may ease the preemption race but fail to address the core issue. What is more, some results suggest that standard antitrust policies aimed at preventing corporate mergers might actually backfire in these specific markets. A merged, joint monopoly that internalizes these synergies actually delays its product launches to build higher quality, ultimately benefiting both producers and consumers.
