Greg Mankiw's Blog: Rent Control
"A price ceiling set below the free-market price has several effects. Suppliers find they can no longer charge what they had been charging for their products. As a result, some suppliers drop out of the market. This represents a reduction in the quantity supplied. Meanwhile, demanders find that they can now buy the same product at a lower price. As a result quantity demanded increases.
As a result of these two actions, quantity demanded exceeds quantity supplied and a shortage emerges. This leads to various forms of non-price competition."Read more here- Price Ceiling
Free Market for the Kidney
Such a market would lead to an efficient allocation of resources, but critics of this plan worry about fairness. A market for organs, they argue, would benefit the rich at the expense of the poor because organs would then be allocated to those most willing and able to pay. But you can also question the fairness of the current system. Now, most of us walk around with an extra organ that we don't really need, while some of our fellow citizens are dying to get one. Is that fair?
And here too- The Kidney Shortage - Price Ceiling
Each one of us, in brief, has a multiple economic personality. Each one of us is producer, taxpayer, consumer. The policies he advocates depend upon the particular aspect under which he thinks of himself at the moment. For he is sometimes Dr. Jekyll and sometimes Mr. Hyde. As a producer he wants inflation (thinking chiefly of his own services or product); as a consumer he wants price ceilings (thinking chiefly of what he has to pay for the products of others). As a consumer he may advocate or acquiesce in subsidies; as a taxpayer he will resent paying them. Each person is likely to think that he can so manage the political forces that he can benefit from a rise for his own product (while his raw material costs are legally held down) and at the same time benefit as a consumer from price control. But the overwhelming majority will be deceiving themselves. For not only must there be at least as much loss as gain from this political manipulation of prices; there must be a great deal more loss than gain, because price-fixing discourages and disrupts employment and production.."Read more - Government Price-Fixing
What Rent Control Does
The effects of rent control become worse the longer the rent control continues. New housing is not built because there is no incentive to build it. With the increase in building costs (commonly as a result of inflation), the old level of rents will not yield a profit. If, as often happens, the government finally recognizes this and exempts new housing from rent control, there is still not an incentive to as much new building as if older buildings were also free of rent control. Depending on the extent of money depreciation since old rents were legally frozen, rents for new housing might be ten or twenty times as high as rent in equivalent space in the old. (This actually happened in France after World War II, for example.) Under such conditions existing tenants in old buildings are indisposed to move, no matter how much their families grow or their existing accommodations deteriorate."Read more - What Rent Control Does
