How We Reported on the $500 Million Sears Deal

To investigate the Sears deal, ProPublica and the Daily Herald reviewed thousands of pages of records, court filings and internal Sears documents. We also commissioned an economic study to examine the long-term effect of the tax deals.

This article was produced in partnership with the Daily Herald, which is a member of the ProPublica Local Reporting Network.

This project is the result of a collaboration between the Daily Herald and the Local Reporting Network of ProPublica, a nonprofit investigative outlet.

To report this story, the Daily Herald and ProPublica reviewed thousands of pages of state and local records obtained under Illinois’ Freedom of Information Act, lawsuit and bankruptcy court filings, and internal Sears documents. We also interviewed state and local officials, economic development experts and people with knowledge of the Sears deal.

To examine the long-term effect of the tax deals, ProPublica and the Daily Herald also commissioned a study by Illinois’ Center for Tax and Budget Accountability, or CTBA, a bipartisan, nonprofit research organization that also lobbies for fiscally responsible state government policies.

CTBA used a statistical method known as a “difference-in-differences,” which measured the economic impact of the Sears deal by comparing before-and-after economic trends in Hoffman Estates to similar, nearby communities over the same time period between 1980 to 2017.

M. Marit Rehavi, a member of ProPublica’s data science advisory board and an associate professor of economics at the Vancouver School of Economics, University of British Columbia, consulted on the analysis.

Protect Independent Journalism

ProPublica is a nonprofit newsroom that produces nonpartisan, evidence-based journalism to expose injustice, corruption and wrongdoing. We were founded ten years ago to fill a growing hole in journalism: newsrooms were (and still are) shrinking, and legacy funding models failing. Deep-dive reporting like ours is slow and expensive, and investigative journalism is a luxury in many newsrooms today — but it remains as critical as ever to democracy and our civic life. A decade (and five Pulitzer Prizes) later, ProPublica has built the largest investigative newsroom in the country. Our work has spurred reform through legislation, at the voting booth, and inside our nation’s most important institutions.

This story you’ve just finished was funded by our readers and we hope it inspires you to make a gift to ProPublica so that we can publish more investigations like this one that holds people in power to account and produces real change.

Your donation will help us ensure that we can continue this critical work. From the Trump Administration, criminal justice, health care, immigration and so much more, we are busier than ever covering stories you won’t see anywhere else. Make your gift of any amount today and join the tens of thousands of ProPublicans across the country, standing up for the power of independent journalism to produce real, lasting change. Thank you.
