Abstract：

 

Multi-sector models use numeraires to aggregate whereas the NIPA use the Fisher index. Since the resulting GDP statistics differ considerably, we must choose one aggregation method to compare model and data GDP. For a model of structural change, we show that the numeraire investment offers the least restrictive way of constructing a balanced growth path (BGP), but the Fisher index is often a measure of welfare changes and captures the growth slowdown due to Baumol’s Costs Disease. We advocate to construct the BGP with the numeraire investment but to connect model GDP calculated with the Fisher index to the data.
