General purpose technologies (GPTs) such as AI enable and require significant complementary investments, including co-invention of new processes, products, business models and human capital. These complementary investments are often intangible and poorly measured in the national accounts, even...

We examine the effects of university-based star scientists on three measures of performance for California biotechnology enterprises: the number of products in development, the number of products on the market, and changes in employment. The `star' concept which Zucker, Darby, and Brewer (1994)...

We examine the relationship between the intellectual capital of scientists making frontier discoveries, the presence of great university bioscience programs, the presence of venture capital firms, other economic variables, and the founding of U.S. biotechnology enterprises during 1976-1989....

Household R&D (or household innovation) is an important source of innovation that has to date been largely overlooked in research related to national accounts. Indeed, it is not currently counted as investment in the literatures on household production and human capital. This paper develops time...

We develop a firm-specific measure of organization capital and estimate it for a sample of approximately 250 companies. We test the validity of the organization capital measure within a widely used investment valuation model and show that our organization capital estimate contributes...

Existing standards prohibit disclosures of internally created intangible capital to firm balance sheets, resulting in a downward bias of reported assets. To characterize off-balance sheet intangible assets, we use transaction prices to estimate this missing intangible capital. On average, our...

We develop a theory of sweat equity—the value of business owners' time and expenses to build customer bases, client lists, and other intangible assets. We discipline the theory using data from U.S. national accounts, business censuses, and brokered sales to estimate a value for sweat equity...

According to the World Bank and the United Nations, human capital is the largest component of human wealth for most countries in the world. There is no question that human capital is critical to individual and society well-being and both present and future growth. This presentation draws upon an...

There are six major measures of human capital, each of which covers at least 130 countries, all of which are described in this paper. These measures are of two distinct types: monetary and index-based. The two monetary versions are those by the World Bank (Lange et al., 2018) and by the United...
