\SetRowColor{LightBackground}
Resource allocation by prices & Competition in the market is what limits how much anyone can charge and still make sales.\{\{nl\}\}The price which one producer is willing to pay for any given resource becomes the price that other producers are forced to pay for that same resource.\{\{nl\}\}Changes in resource prices have repercussions in the prices of other resources. \tn

\{\{nobreak\}\}Demand under Rent Control & Just as price fluctuations allocate scarce resources which have alternative uses, price controls which limit those fluctuations reduce the incentives for individuals to limit their own use of scarce resources desired by others. \tn 
% Row Count 15 (+ 11)
% Row 2
\SetRowColor{LightBackground}
Supply under Rent Control & The rental housing stock is relatively fixed in the short term, so that a shortage occurs first because more people want more housing at the artificially low price. Later, there may be a real increase in scarcity as well, as rental units deteriorate more rapidly with reduced maintenance, while not enough new units are being built to replace them as they wear out, because new privately built housing can be unprofitable under rent control. \tn

% Row 3
\SetRowColor{LightBackground}
The Politics of Rent Control & Often it is politically effective to represent rent control as a way to keep greedy landlords from gouging the poor with "unconscionable" rents. In reality, rates of return on investments in housing are seldom higher than on alternative investments, and landlords are often people of very modest means. \tn 
% Row Count 15 (+ 15)
% Row 4
\SetRowColor{white}
Scarcity vs. Shortage & Keep in mind the distinction between an increased scarcity - where fewer goods are available relative to the population- and a shortage as a {\bf{price}} phenomenon. Just as there can be a growing shortage without an increased scarcity, so there can be a growing scarcity without a shortage. \tn 
% Row Count 29 (+ 14)
% Row 5
\SetRowColor{LightBackground}
Hoarding & Hoarding is a special case of the more general economic principle that more is demanded at a lower price and the corollary that price controls allow lower priority uses to preempt higher priority uses, increasing the severity of the shortages. \tn

% Row 6

Black Markets & Price controls almost invariably produce black markets, where prices are not only higher than the legally permitted prices, but also higher than they would be in a free market, since the legal risks, must also be compensated. \tn 
% Row Count 11 (+ 11)
% Row 7
\SetRowColor{white}
Quality Deterioration & Under price control, the amount of a product demanded at an artificially low price exceeds the amount supplied, so there is no need to spend resources on quality, as they will be sold anyway. \tn 
% Row Count 21 (+ 10)
% Row 8
\SetRowColor{LightBackground}
Price "Floors" and Surpluses & Price control in the form of a "floor" under prices, preventing these prices from falling further, produces surpluses as dramatic as the shortages produced by price control in the form of a "ceiling" preventing prices from raising higher. \tn

Systemic Causation & While causation can sometimes be explained by intentional actions and sometimes by systemic interactions, too often the the results of systemic interactions are falsely explained by individual intentions. \tn

Incremental Substitution & As important as it is to understand the role of substitutions, it is also important to keep in mind that the efficient allocation of resources requires that these substitutions be {\bf{incremental}}, not total. \tn

Subsidies and Taxes & Prices charged to the consumers of such specially taxed or specially subsidised goods and services do not convey the real costs of producing them and therefore do not lead to the same trade-offs as if they did. \tn

The Meaning of "Costs" & One reason for the popularity of price controls is the confusion between prices and costs. Once the distinction is recognised then it's not very surprising that price controls have the negative consequences that they do, because price ceilings mean a refusal to pay the full costs. \tn
