An illustration from the original "Moore's Law" article.

I study information technology (IT) innovation, its effects on economic growth, and the economics of the IT supply chain. If you're working in these areas, I'd be interested to hear about it.

It's easy to jump from what IT can do to the conclusion it will change industrial activity. Measuring that effect is far harder. Along many dimensions, existing data does not support that effort and much of my work has focused on fixing that problem. I give a twenty minute overview of these challenges in this video

Building on that measurement foundation, I consider such questions as the prospects for AI to transform the economy, the effects of political, public health, and climate shocks on the global electronics supply chain, and the history of electronics innovation and its importance to productivity.

  • Risk in the Electronics Supply Chain from Soup to Nuts Abstract: Fueled by the effects of the COVID-19 pandemic, climate change, and rising tension between mainland China and Taiwan, policymakers have moved supply chain risk to the front burner with a particular focus on the electronics sector. To support rigorous discussion of the this issue, we provide annual indicators from 2000 forward for risk of political instability, natural disaster, industrial accident, and transportation in the electronics sector. Broadly, risk increased through roughly 2010 as China rapidly increased its share of global electronics production. Since 2010, risk has either held steady or declined, depending on type. Risk profiles vary substantially across the industries that make up the sector---mineral processing, chip manufacturing, equipment assembly, etc.---and across types of equipment. Locations producing low- to moderate-value products in high volume are characterized by higher supply chain risk. In addition to these supply shocks, demand shocks can play an important role in supply chain disruptions, as illustrated by the COVID-19 pandemic.
  • Nodes and Edges in the Electronics Sector (With Nicole Hoffman) Abstract: We document the pattern of activity (production, bilateral trade, and sales) by country for electronic components and final electronics (computers, communication equipment, and special-purpose electronics) for the 1992-2024 period. We provide quantitative indicators of the complexity of the network and the elasticity of the system with respect to trade policy changes.

Economic Measurement
  • The Digital Economy: Three Fundamental Measurement Challenges Presentation Abstract: Previous critical reviews of price statistics have focused on the shortcomings of individual price indexes, including incomplete accounting for substitution among items, confounding of inflation and quality change, among others. \emph{Systemic problems} in the inflation measurement system have been largely ignored, including inconsistency in price measures across products, over time, and among countries. We illustrate these problems using examples from information technology (IT), focusing on macroeconomic analysis. We then identify and discuss three barriers to the correction of these problems in the statistical system: Balkanization, perfectionism, and recency bias.
  • Transistors all the way Down: Viability of Direct Volume Measurement (and Price Indexes) for Semiconductors (with Adrian Hamins-Puertolas and Molly Harnish) Abstract: he semiconductor (solid-state electronics) industry is a prime example of global production sharing, of the translation of basic research into productivity, and of the power of a general-purpose technology to boost economic growth. Study of these questions requires measures of industry output and prices that are complete and consistent across time, economies, and products. Such data are not currently available. We solve this problem by measuring volume directly using plant-level capacity, industry utilization, and parameters for the state of technology. Our output and implicit price indexes for microprocessors, memory chips, and other logic for the 1996-2023 period compare favorably to existing indexes deemed to be reliable. However, in some periods, our output and price measures suggest rather different stylized facts for the global industry, including a smaller surge in chip production in the late 1990s and rapid price declines for GPUs in recent years.
