The Data Assembly is an initiative from The GovLab supported by the Henry Luce Foundation to solicit diverse, actionable public input on data re-use for crisis response in the United States. The initiative began in the summer of 2020 with an initial focus on the response to the COVID-19 pandemic...

As the COVID-19 pandemic continues to upend the way people move, work, and gather, governments, businesses, and public health researchers have looked increasingly at mobility data to support pandemic response. This data, assets that describe human location and movement, generally has been...

If we are to take action on climate change, support environmental justice and deliver a just transition for more resilient societies we urgently need to provide access, connect and (re)use environment related data (ERD). Several different projects are attempting to improve access, connection and...

We use U.S. county-level data to estimate convergence rates for 22 individual states. We find significant heterogeneity. E.g., the California estimate is 19.9 percent and the New York estimate is 3.3 percent. Convergence rates are essentially uncorrelated with income levels.

We use US county level data (3,058 observations) from 1970 to 1998 to explore the relationship between economic growth and the extent of government employment at three levels: federal, state and local. We find that increases in federal, state and local government employments are all negatively...

We thank three anonymous referees for thoughtful comments and suggestions which we found very constructive and helpful. We are particularly grateful to the editor, Al Klevorick, for his advice and painstaking guidance through the multiple revision process. We thank Robert Barsky, Susanto Basu,...

We offer the first direct evidence of an implicit contract in a goods market. The evidence we offer comes from the market for Coca-Cola. We demonstrate that the Coca-Cola Company left a substantial amount of written evidence of its implicit contract with its consumers-a very explicit form of an...

We investigate emigrant self-selection according to institutional quality using up to 3,566 observations on bilateral migration flows from 77 countries over the 1990-2000 period. We relate these flows to differences in political and economic institutions. We improve and expand upon previous...

We study the cost of breaching an implicit contract in a goods market, building on a recent study that documented the presence of such a contract in the Coca-Cola market, in the US, during 1886‒1959. The implicit contract promised a serving of Coca-Cola of a constant quality (the “real...
