Jim Follain has a proposal for empirical macro

He writes:

First, let’s do more research to help reduce the uncertainty regarding the fiscal situation we face and the new, modern and more complex economy in which we live. This step will involve de-emphasizing a number of metrics underlying macroeconomics built around national totals, such as national income, GDP and the aggregate unemployment rate. Instead, we are wise to take a more geographically granular view of our economy that measures regional, state and local economic activity and adapts policies specific to these areas. Focusing upon the national aggregate or the national average masks the extraordinary variation among markets in this country and, indeed, can even make it harder to identify seriously stressful events until it’s too late. This is difficult to do, but c’est la vie.
