This paper examines the output contributions of capital and labor deployed in information systems (IS) at the firm level during the period 1988-91 throughout the business sector, using two different sources of data on these inputs. Our production function estimates suggest that there are...

Modern information technologies have greatly facilitated timely dissemination of information to a broad base of investors at low costs. To examine their effects on the real economy, we exploit the staggered implementation of the EDGAR system from 1993 to 1996 as a shock to information...

Supporters of touch-screen voting claim it is a highly reliable voting technology, while a growing number of critics argue that paperless electronic voting systems are vulnerable to fraud. In this paper we use county-level data on voting technologies in the 2000 and 2004 presidential elections...

We use administrative corporate tax data from the IRS to study a particular form of tax avoidance for US multinational corporations (MNCs). This strategy relies on cost sharing agreements (CSAs), which govern joint R&D efforts conducted with foreign affiliates and allow US MNCs to shift profits...

This paper develops a transparent, simplified version of Carnehl and Schneider (2025)'s model of knowledge creation. Our tractable framework, which yields closed-form solutions for key welfare trade-offs, preserves the essential economic mechanisms while eliminating mathematical complexity. We...

We document the structural transformation of innovation using historical patent data since the 1850s, along with R&D expenditure and TFP growth for the post-war period. Over time, innovation has shifted from agricultural sectors to manufacturing, and, more recently, to services. We develop and...

We quantify the private returns to government R&D contracts awarded to firms. We present new evidence that R&D contracts not only finance innovation but also embed an implicit government guarantee of noncompetitive future procurement for the winning R&D contractor. We measure its private value...

Research which explores unchartered waters has a high potential for major impact but also carries a higher uncertainty of having impact. Such explorative research is often described as taking a novel approach. This study examines the complex relationship between pursuing a novel approach and...

A well-developed theoretical literature -- dating back at least to Nordhaus (1969) -- has analyzed optimal patent policy design. We re-present the core trade-off of the Nordhaus model and highlight an empirical question which emerges from the Nordhaus framework as a key input into optimal patent...

We study the extent to which eminent scientists shape the vitality of their areas of scientific inquiry by examining entry rates into the subfields of 452 academic life scientists who pass away prematurely. Consistent with previous research, the flow of articles by collaborators into affected...
