The publication

What to expect.

The Diff uses finance and technology as starting points for understanding a wider economy. Issues pair an extended argument about a company, event, or trend with annotated links that test or extend the argument. Its appeal is the connection between business strategy and the incentives of investors, employees, customers, and institutions. The archive ranges across software, logistics, macroeconomics, and financial structures. Read it when you want to examine the mechanism behind an interesting business development.
