Covid-19 is a global pandemic inflicting large health and economic costs. In his previous book, The Pandemic Information Gap: The Brutal Economics of COVID-19 (MIT Press, 2020), economist Joshua Gans explains that those costs have been so large because governments and others have lacked the information needed to control the pandemic. Unless we know who is infectious, we can't break the chains of transmission, which results in the escalation of our problems. Pandemics, he writes, are information problems.

Now, in this follow-up book, Gans outlines the solution to the information gap. By engaging in rapid, frequent screening, we can control the pandemic and restore normality. We can lower the number of cases, break chains of transmission, and make it safe for people to interact again. This will require changing our mindset about testing, gathering the right information, and matching that information to the right decisions. We have the ingredients to do all these things. We just need to put them together in a scalable and sustainable system. This book is a guide to the issues and trade-offs that policymakers and other key decision-makers need to grapple with and follow.

Preface

My Covid-19 pandemic story is that I wrote a book on the pandemic. Actually, two books, a couple of papers, lots of opinion pieces, and a newsletter. All about the pandemic. And now I have written another book.

This one is a sequel to The Pandemic Information Gap: The Brutal Economics of COVID-19, which was published by MIT Press in November 2020. I finished that book in July, but by December, I realized that there was more to say. The Pandemic Information Gap set up the issue, but it offered little in the way of details. During months of study, I discovered that the details mattered. While working on an initiative to bring rapid antigen screens to workplaces at scale, I also found that these crucial details were often misunderstood by people, including policymakers. As a translator of economic thinking for this crisis, I saw the need to bring more clarity by writing this book.

Why a book? Since August 2020, I have been writing a newsletter every other day about how Covid-19 issues intersect with economics in the context of daily events.1 This book aims to unify and clarify some larger themes. In addition, we now have real solutions to the information problems that pervade today’s pandemic management. Therefore, I saw an important need to present these solutions in one manuscript.

Who is this book for? My previous Covid-19 book had a wide audience in mind. This time, my audience comprises people who are dealing with the day-to-day challenge of sustaining economic activity while the pandemic rages. What I offer here are solutions, along with the arguments that support them. The book will be of use to people looking for those solutions, including policymakers.

The pandemic creates an urgent need for solutions. I have been writing about the pandemic for almost a year and I know how quickly things can change. Some issues become more (or less) important and salient. So, I plan to update this book and produce new editions as needed. It will evolve while I also keep readers up to date through my newsletter.

As with my previous book on this topic, I could not have written this one without help. I am grateful to Carl Bergstrom, Thomas Hellmann, Richard Holden, Andrew Leigh, Deb MacKenzie, Tiff Macklem, Lukasz Rachel, and Alex Tabarrok. They all, at different times, have helped me think through the arguments presented in this book. Thanks also to Glenn McMahan for copy editing this book in record time. I also owe a special debt to my frontline, rapid screening colleagues: Ajay Agrawal, Chris Deverell, Avi Goldfarb, Chuck Lamarre, Laura Rosella, Sonia Sennik, and Janice Stein. They inspired me to keep going and fighting for these solutions. Each is a world-leading driving force in the effort to get these solutions into the field. I hope that a future edition of this book can describe in detail what the group2 has achieved.

The Pandemic Information Gap

The Gap

Pandemics are known to be public health crises. Spreading viruses can have widespread, serious, and even fatal health consequences. To counter them, people need to be protected, treated and, eventually, vaccinated.

Pandemics also have dire economic consequences. The health-care costs are significant, but in many respects, they pale in comparison to the economic and social costs that occur as people seek to protect their health. Some health protections—mandatory distancing, lockdowns, travel restrictions, personal protective equipment, and mask wearing—are imposed by governments. Covid-19 has demonstrated that people will protect themselves even without government mandates.

Efforts to protect health during this pandemic have resulted in major disruptions. Workers have abandoned city centers and chosen to work from home. Leisure activities—travel, going out, hanging out—have been shunned. As schools have closed, it has been hard, if not impossible, for parents (especially women) to work. This has resulted in some of the largest additions to unemployment queues in history and a long-lasting recession. Governments have tried to stem the economic consequences with rent and mortgage protections, handouts, business loans, and the like, but nothing has shielded people from the life-changing consequences of the Covid-19 pandemic. And, in contrast with previous recessions, this time the less well-off have suffered most.3

These economic consequences are caused by the public health crisis; therefore, a full resolution of that crisis would resolve them. But the scale of this crisis is such that its resolution will take time.

The fundamental problem we face in the meantime is an information problem. Specifically:

The economic costs of the pandemic arise from the fundamental problem that we cannot tell who is infectious in order to isolate them from others.

I described this conclusion in The Pandemic Information Gap. If we had a way to quickly determine who is infectious, we could separate them from others and protect people as they go about their business. The problem we have faced with Covid-19 is that this information gap has been wide. In July 2020, for instance, a study from England showed that, at that time, only one in 3,900 people were infectious with Covid-19.4 However, because we did not know the identity of that one infectious person, 3,899 other people treated each other as infectious. When you believe most people could be infectious, you stay away from all people.

The logic behind this conclusion is simple. Pandemics are a problem because the disease spreads from infectious people to susceptible people. As a result, we deal with pandemics solely with health measures, such as developing a vaccine or by isolating people. These options are either slow or very costly.

By contrast, what might happen if we could manage pandemics as an information problem? In this case, we would focus on identifying infectious people and isolating only those individuals. To accomplish this, we would need a method of identifying infectious people.

For some pandemics, the nature of the disease solves the information problem for us. With some viruses, people show symptoms when they are infected. This is what happened during the SARS, MERS, and Ebola outbreaks. Consequently, those pandemics could be suppressed in a matter of months.

Unfortunately, Covid-19 spreads even when people are asymptomatic. Taking this into account, some countries (e.g., Taiwan, Iceland, Mongolia, and South Korea) treated Covid-19 as an information problem from the start. They quickly developed tests and used them to test broad sections of the population. Then they used contact tracing to identify who was more likely to be infectious. By treating the spread of Covid-19 as an information problem, these countries were able to turn their pandemics into something relatively short-lived, like a SARS outbreak.

None of this is news, but many countries still have not taken seriously the idea that stemming the spread of Covid-19 requires solving the information problem. Some countries are do...
