We develop measures of labor-saving and labor-augmenting technology exposure using textual analysis of patents and job tasks. Using US administrative data, we show that both measures negatively predict earnings growth of individual incumbent workers. While labor-saving technologies predict...

What are a country's policy options in the face of emerging technologies development in a global economy? To answer this question, we examine optimal dynamic policies in an open economy where technology is endogenously accumulated through R&D innovation. Our key insight is that a country has...

This paper examines the evolving structure and competition dynamics of the rapidly growing market for foundation models, with a focus on large language models (LLMs). We describe the technological characteristics that shape the AI industry and have given rise to fierce competition among the...

We model how an increase in Work-from-Home (WFH) productivity differentially affects workers using a framework in which some workers cannot work offsite, some are hybrid, and some are completely remote. The improvement in WFH productivity increases housing demand and thus housing prices since...

"We prove that the change in welfare of a representative consumer is summarized by the current and expected future values of the standard Solow productivity residual.

In this paper we argue that an important source of the recent increase in outsourcing is the computer and information technology revolution, characterized by increased rates of technological change. Our model shows that an increase in the pace of technological change increases outsourcing...
