A funny thing about blogging — often you write about something and then soon after you come across something related.

To wit, soon after my post about lack of macro data, via Flowing Data I came across the G-Econ project, by William Nordhaus and others at Yale. It provides (estimates of) economic data for all 27,500 1-degree by 1-degree cells (approx 100km x 100km) on the globe.

Obviously official economic statistics are not calculated at this level of resolution, so the G-Econ group must have used some kind of estimation technique. Nevertheless, it’s a very important contribution to filling the data gaps.
