We study the composition of bank loan portfolios during the transition of the real sector to a knowledge economy where firms increasingly use intangible capital. Exploiting heterogeneity in bank exposure to the compositional shift from tangible to intangible capital, we show that exposed banks...

This paper estimates the long run elasticity of the demand for fixed nonresidential capital (both equipment and structures) to changes in its user cost using a quarterly panel of two-digit manufacturing data from South Africa from 1970 to 2001. Using a difference specification that does not rely...

I use micro data to quantify key features of U.S. firm financing. In particular, I establish that a substantial 35% of firms' investment is funded using financial markets. I then construct a dynamic equilibrium model that matches these features and fit the model to business cycle data using...

The widespread emergence of intangible technologies in recent decades may have significantly hurt output growth -- even when these technologies replaced considerably less productive tangible technologies -- because of structurally low interest rates caused by demographic forces. This insight is...

This paper explores the hypothesis that the rise in intangible capital is a fundamental driver of the secular trend in US corporate cash holdings over the last decades. Using a new measure, we show that intangible capital is the most important firm-level determinant of corporate cash holdings....

This paper analyzes the sources of U.S. productivity growth in recent years using both aggregate and industry-level data. We confirm the central role for information technology (IT) in the productivity revival during 1995-2000 and show that IT played a significant, though smaller, role after...

This paper studies optimal debt maturity in an economy with repayment enforcement frictions and investors disagree about repayment probabilities. The optimal debt maturity choice is a mix of long- and short-term debt securities. Spreading risky debt claims on cash flows over time allows debt to...

Despite the recent patch of sluggish growth, the U.S. economy has experienced a period of remarkable stability since the mid-1980s. One popular explanation attributes the diminished variability of economic activity to information-technology-led improvements in inventory management. Our results,...

After reviewing the state of digitalization---the use of digital information technology (IT) throughout the economy---we consider the slippery concept of a distinct digital economy and efforts to record it in national accounts. We then anchor the digital economy in a growth accounting framework,...

This paper reassesses the link between ICT prices, technology, and productivity. To understand how the ICT sector could come to the rescue of a whole economy, we extend a multi-sector model due to Oulton (2012) to include ICT services (e.g., cloud services) and use it to calibrate the...
