Abstract
Traditional asset management strategy has emphasized building barriers to entry or closely guarding unique assets to maintain a firm’s comparative advantage. A new "Inverted Firm" paradigm, however, has emerged. Under this strategy, firms share data seeking to become platforms by opening digital services to third-parties and capturing part of their external surplus. This contrasts with a "pipeline" strategy where the firm itself creates value. This paper quantitatively estimates the effect of adopting an inverted firm strategy through the lens of Application Programming Interfaces (APIs), a key enabling technology. Using both public data and that of a private API development firm, we document rapid growth of the API network and connecting apps since 2005. We then perform difference-in-difference and synthetic control analyses and find that public firms adopting public APIs grew an additional 38.7% over sixteen years relative to similar non-adopters. We find no significant effect from the use of APIs purely for internal productivity, the pipeline strategy. Within the subset of firms that adopt public APIs, those that attract more third-party complementors and those that become more central to the network see faster growth. Using variation in network centrality caused by API degradation, an instrumental variables analysis confirms a causal role for APIs in firm market value. Finally, we document an important downside of public APIs: increased risk of data breach. Overall, these facts lead us to conclude that APIs have a large and positive impact on economic growth and do so primarily by enabling an inverted firm strategy.
