Data as a Networked Asset
Abstract
Data is non-rival: a firm’s customer data informs other firms about their customers. We uncover a network of inter-firm data conduits embedded in mobile applications. Data sharing induces comovement in firms’ operational, financial, and stock-market performances, propagates shocks (e.g., cyberattacks), and induces herding in product design. Apple’s privacy policy—a shock to inter-firm data flows—weakened these patterns. We develop a dynamic network model, where firms’ performance and growth are interconnected through a data-sharing network. A network-augmented Gordon growth formula emerges for valuing data-generated cash flows. Our valuation metrics incorporate high-order and long-term spillovers and reveal systemically important firms.The Real Cost of Benchmarking
Abstract
Benchmark-linked capital flows increase firms' CAPM βs, thereby raising managers' perceived cost of equity and reducing investment. Using exogenous variation from Russell and S&P 500 reconstitutions, we show that inclusion in a benchmark stock index increases a stock's CAPM β. Managers interpret the higher β as a higher cost of equity and reduce investment. Consistent with this mechanism, benchmark inclusion also raises the perceived cost of equity among stock analysts and regulators. Industries with larger increases in βs due to benchmarking have accumulated less capital over the past two decades. Benchmark-induced changes in the cross-section of CAPM βs do not cancel out but affect aggregate investment because higher βs fall on many firms with high investment elasticities, while lower βs benefit a few large but inelastic firms. This mechanism can account for the majority of the missing investment puzzle.Discussant(s)
