Writing on the Heritage Foundation's blog, The Foundry, rbluey calls me out for my bashing (here and here) of Brian Riedl's paper Tax Rebates Will Not Stimulate The Economy and recent statements he made in a BNA article($).
The following is my response.
Coming back to tenth-grade economics, in which we learn that "economic growth" refers to the change in the value of all goods and services (gross domestic product, or GDP) produced over a given time period in a given set of product and service markets, we can make any number of assertions that activity X will result in an increased value of such production.
Riedl's paper relies on this definition economic growth ("By definition, an economy grows when it produces more goods and services than it did the year before."), but then claims that increased consumer expenditure, prompted by an increase in consumer income enabled by government transfers (i.e. tax rebates), do not, in fact cause the economy to produce more stuff in 2008 than it would have without such rebates. This is wrong (see e.g., CBO Director Peter Orszag, Federal Reserve Board Chairman Ben Bernanke, Harvard Economics professor and former Chairman of the Council of Economic Advisers and President Reagan's chief economic adviser Martin Feldstein, and former Clinton Treasury Secretary Lawrence Summers).
