Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

The advantage of using a simple heuristic to mine the price/quantity data directly is that you don't have to conduct a large, expensive survey every ten years or so to group sectors into fixprice and flexprice.

Incidentally, can you point me in the direction of some of the literature on those studies? And do you know whether price/quantity data exists in digital that far back? It would certainly help avoid the most common model-making traps if we could test the models on real historical data before letting it loose on contemporary data...

I don't know where the full times series data are collated, but the components of the PPI and CPI indices would have a heck of a lot of disaggregated price level data in index form.

So for an example of coverage of monthly price indices, Table 5. Producer price indexes for the net output of selected industries and their products (pdf)

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
