Intangible assets are a large and growing part of firms’ capital stocks. Intangibles are accumulated via investment—foregoing consumption today for output in the future—but they lack a physical presence. Rather than stopping with this “lack,” we instead focus on the positive properties of intangibles. Specifically, intangibles must be stored, so characteristics of the storage medium have important implications for their value and use. These properties include non-rivalry, allowing the intangible to be used simultaneously in different production streams, and limited excludability, which prevents the firm from capturing all the benefits or rents from the intangible. We develop these ideas in a simple way to illustrate how outcomes such as scalability and distribution of ownership follow. We discuss how intangibles can help to understand important trends in macroeconomics and finance, including productivity, factor shares, inequality, investment and valuation, rents and market power, and firm financing.

Emi Nakamura is the 2019 recipient of the John Bates Clark Medal from the American Economic Association. Emi is an empirical macroeconomist whose work has studied the nature of price-setting and the effects of monetary and fiscal policies, among other issues, and has been notable for using less aggregated data, while addressing central questions about the macroeconomy. We describe Emi's key research contributions, with particular emphasis on those identified by the Honors and Awards Committee of the American Economic Association in her Clark Medal citation, as well as her broader contributions to the field of economics.
