Frank ----- Would some PEN-L comrade be kind enough to instruct me on how I might access time series data (for the U.S.) on 1) aggregate capital/output ratios both a) capital stock/GDP and b) capital depreciation/GDP Paul ---- Over the last couple of weeks I have been working with the BEA diskettes on capital stocks and flows by sector, and on the i/o tables, these would provide the information you need and seem to be pretty easy to process. I believe they cost about $40 each.
