Improvements in the software that provides hardware management, user interface and platform functions have played a central role in the growth and transformation of the personal computer (PC) industry. Several forces shape the design of these 'operating system' products and propel their...

According to our analysis, pre-invasion views about the likely course of the Iraq intervention imply present value costs for the United States in the range of $100 to $870 billion. Our estimated present value cost for the containment policy is nearly $300 billion and ranges upward to $700...

We analyze entry, pricing and product design in a model with differentiated products. Under plausible conditions, entry into an initially monopolized market leads to higher prices for some, possibly all, consumers. Entry can induce a misallocation of goods to consumers, segment the market in a...

Building on Baker, Bloom and Davis (2016), I construct a monthly index of Global Economic Policy Uncertainty (GEPU) from January 1997. The GEPU Index is a GDP-weighted average of national EPU indices for 16 countries that account for two-thirds of global output. Each national EPU index reflects...

When match formation is costly and wage determination is decentralized, privately optimal investments in job and worker quality diverge from socially efficient outcomes. To explore this issue, I consider search equilibrium environments with endogenous quality distributions for jobs and workers....

This paper investigates movements in relative wages and wage inequality across thirteen of the world's major economies. Focusing on wages received by full-time male workers, the investigation uncovers several empirical regularities: (1) Most advanced industrialized economies show increases,...

I review evidence of rising policy uncertainty in the U.S. and global economies, drawing heavily on newspaper-based measures. Examples from countries around the world illustrate the role of political and policy developments as drivers of fluctuations in economic uncertainty. I also highlight the...

The COVID-19 pandemic instigated a big shift in working arrangements. I first describe the scale of this shift in the United States, drawing on the Survey of Working Arrangements and Attitudes and other sources. I then review differences, circa 2023, in work-from-home rates across industries,...

Two extraordinary U.S. labor market developments facilitated the sharp disinflation in 2022-23 without raising the unemployment rate. First, pandemic-driven infection worries and social distancing intentions caused a sizable drag on labor force participation that began to reverse in the first...

We develop an economic framework for valuing improvements to health and life expectancy, based on individuals' willingness to pay. We then apply the framework to past and prospective reductions in mortality risks, both overall and for specific life-threatening diseases. We calculate (i) the...
