I've got a very weak signal <a href=" http://paultierney.com/best-homework-service/ ">unlucky father statics homework help sadness welcome</a> The point about price controls is that they create shortages. This is because by keeping prices artificially low, demand is increased to the point where supply can no longer keep up. Where demand is inelastic, as with energy or food, a slightly different effect is observed, though the outcome – shortages – is still the same. Suppliers simply refuse to produce for the assigned price. This effect was quite commonly observed in the US during the Nixon price controls of the 1970s, when supermarket shelves were left half filled.
