TCC: (Net Fixed Assets of productive sectors in) chained 1996 dollars per hour (of productive labour) OCC: (Net Fixed Assets of productive sectors in) chained 1996 dollars per chained 1996 dollar (of the gross wages paid to productive labour). The denominator is deflated by an implicit price deflator for NDP, so the real wages are product wages.

When doing so, what time period do you use. Annual BLS data adjusted to match NIPA data. > What is the dimension of TCC, and what is your base year in > using fixed price valuation. See above for dimension. 1996 prices. > How do you account for the introduction > of qualitatively new MOP over the period? This is a well-known difficulty which is the subject of much debate. NIPA use hedonic price indices for computer hardware, eg. Does this help? Simon
