Many techniques which had made the automobile affordable made housing affordable: standardization of design and small, repetitive assembly tasks, advertising, and a smooth flow of capital.

Curving streets, greenbelt parks, neighborhood pools, and community entry monumentation appeared. Diverse floor plans with differing room counts, and multiple elevations (different exterior "looks" for the same plan) appeared. Developers remained competitive with each other on everything, including location, community amenities, kitchen appliance packages, and price. Today,
228-434: A method of squeezing out speculators from a transaction, but they may have their own perverse effects by the winner's curse . The winner's curse is, however, not very significant to markets with high liquidity for both buyers and sellers, as the auction for selling the product and the auction for buying the product occur simultaneously, and the two prices are separated only by a relatively small spread. That mechanism prevents
266-658: A number of attempts over the years to introduce regulations and restrictions to try to limit or reduce the impact of speculators. States often enact such financial regulation in response to a crisis. Note for example the Bubble Act 1720 , which the British government passed at the height of the South Sea Bubble to try to stop speculation in such schemes. It remained in place for over a hundred years until repealed in 1825. The Glass–Steagall Act passed in 1933 during

In certain residential areas, especially rural , large tracts of land may have no services whatever, such that residents seeking services must use a motor vehicle or other transportation, so the need for transportation has resulted in land development following existing or planned transport infrastructure such as rail and road. Development patterns may be regulated by restrictive covenants contained in

418-749: A typical residential development in the United States might include traffic calming features such as a slowly winding street , dead-end road , or looped road lined with homes. Suburban developments help form the stereotypical image of a "suburban America" and are generally associated with the American middle-class .

The U.S. Commodity Futures Trading Commission defines a speculator as "a trader who does not hedge, but who trades with the objective of achieving profits through the successful anticipation of price movements". The agency emphasizes that speculators serve important market functions, but defines excessive speculation as harmful to
646-492: The Commodity Futures Trading Commission (CFTC) has proposed regulations aimed at limiting speculation in futures markets by instituting position limits.

The number of shareholders increased, perhaps, from 4.4 million in 1900 to 26 million in 1932. The view of what distinguishes investment from speculation and speculation from excessive speculation varies widely among pundits, legislators and academics. Some sources note that speculation
874-417: The benefits of speculation: Let's consider some of the principles that explain the causes of shortages and surpluses and the role of speculators. When a harvest is too small to satisfy consumption at its normal rate, speculators come in, hoping to profit from the scarcity by buying. Their purchases raise the price, thereby checking consumption so that the smaller supply will last longer. Producers encouraged by
912-408: The bubble is followed by a precipitous collapse fueled by the same phenomenon. Speculative bubbles are essentially social epidemics whose contagion is mediated by the structure of the market. Some economists link asset price movements within a bubble to fundamental economic factors such as cash flows and discount rates. In 1936, John Maynard Keynes wrote: "Speculators may do no harm as bubbles on
950-406: The economy is price discovery . On the other hand, as more speculators participate in a market, underlying real demand and supply can diminish compared to trading volume, and prices may become distorted. Speculators perform a risk-bearing role that can be beneficial to society. For example, a farmer might consider planting corn on unused farmland . However, he might not want to do so because he
988-775: The expanding demand for home ownership. Post–World War II economic expansion in major cities of the United States, especially New York City and Los Angeles produced a demand for thousands of new homes, which was largely met by speculative building. Its large-scale practitioners disliked the term "property speculator" and coined the new name "residential development" for their activity. Entire farms and ranches were subdivided and developed, often with one individual or company controlling all aspects of entitlement (permits), land development (streets and grading), infrastructure (utilities and sewage disposal), and housing. Communities like Levittown, Long Island or Lakewood south of Los Angeles saw new homes sold at unprecedented rates—more than one

1064-423: The high price further lessen the shortage by growing or importing to reduce the shortage. On the other side, when the price is higher than the speculators think the facts warrant, they sell. This reduces prices, encouraging consumption and exports and helping to reduce the surplus. Another service provided by speculators to a market is that by risking their own capital in the hope of profit, they add liquidity to

If any market, such as pork bellies , had no speculators, only producers (hog farmers) and consumers (butchers, etc.) would participate. With fewer players in the market, there would be a larger spread between the current bid and the asking price of pork bellies. Any new entrant in
1254-421: The market who wanted to trade pork bellies would be forced to accept this illiquid market and might trade at market prices with large bid–ask spreads or even face difficulty finding a co-party to buy or sell to. By contrast, a commodity speculator may profit from the difference in the spread and, in competition with other speculators, reduce the spread. Some schools of thought argue that speculators increase
1292-520: The principles of successful investment in his 1933 report: "a balanced investment position... and if possible, opposed risks". It is controversial whether the presence of speculators increases or decreases short-term volatility in a market. Their provision of capital and information may help stabilize prices closer to their true values. On the other hand, crowd behavior and positive feedback loops in market participants may also increase volatility. The economic disadvantages of speculation have resulted in
1330-670: The proper functioning of futures markets. According to Benjamin Graham in The Intelligent Investor , the prototypical defensive investor is "one interested chiefly in safety plus freedom from bother". He adds that "some speculation is necessary and unavoidable, for, in many common-stock situations, there are substantial possibilities of both profit and loss, and the risks therein must be assumed by someone." Thus, many long-term investors, even those who buy and hold for decades, may be classified as speculators, excepting only
1368-453: The rare few who are primarily motivated by income or safety of principal and not eventually selling at a profit. Nicholas Kaldor has long argued for the price-stabilizing role of speculators, who tend to even out "price-fluctuations due to changes in the conditions of demand or supply", by possessing "better than average foresight". This view was later echoed by the speculator Victor Niederhoffer , in "The Speculator as Hero", who describes
1406-659: The time the Forward Markets Commission was established in 1953, the government felt that derivative markets increased speculation, which led to increased food costs and price instabilities. In 1953 it finally prohibited options- and futures-trading altogether. The restrictions were not lifted until the 1980s. In the United States , following passage of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010,
