- [This is definitely off the subject of woodworking (except as it relates to
- supply and demand of woodworking machines), but....]
-
- No, no, no, silly.
-
- Supply and demand works the other way. For a given level of demand,
- an increased supply results in decreasing prices. The market drives
- the prices down. Likewise, for the same level of demand, a constricted
- supply drives the prices UP.
-
- Conversely, for a given level of supply, increased demand will have the
- effect of bidding the price up. And, to complete the picture, decreased
- demand means that the existing supply will go begging; i.e. the price
- drops. This is the situation alluded to above.
-
- That's classical supply and demand. The only case I can think of that fits
- your explanation is the case of new manufacture, where demand is not large
- enough to support multiple manufacturers. In that case, one manufacturer
- may develop a monopoly on a small market and drive the price artifically high.
- Of course if he did that, the high price would be a call to other manufacturers
- to enter the market....but that's for new equipment.
