Monopoly

External link: Salt and the evolution of monopoly (salt.org.il). In conclusion, N₂O induces its effects through classical volatile anaesthetic mechanisms like NMDA receptor antagonist, GABA-A potentiation and potassium channel activation as well as novel mechanisms such as a benzodiazepine-like effect and stimulating endogenous opioid receptors. Advocates of laissez-faire capitalism, such as the Austrian school, maintain that a salt monopoly would never develop without such government intervention. Exactly how N₂O causes the release of opioids is still uncertain. Anyone was allowed to purchase salt; however, strict legal controls were in place over who was allowed to sell and distribute salt. It seems N₂O-induced released of endogenous opioids causes disinhibition of brainstem noradrenergic neurons, which descend into the spinal cord and inhibit pain signaling. The "Gabelle", a notoriously high tax levied upon salt, played a role in the start of the French Revolution and is possibly the most cruel example in recent history. Indeed, alpha2B-adrenoreceptor knockout mice or animals depleted in noradrenaline are nearly completely resistant to the antinociceptive effects of N₂O (Sawamura et al., 2000; Zhang et al., 1999).

Changing sea levels flooded many of these sources during certain periods and caused salt "famines" and communities were left to the mercy of those who monopolised these few inland sources. Conversely, alpha-adrenoreceptor antagonists block the antinociceptive effects of N₂O when given directly to the spinal cord, but not when applied directly to the brain (Fang et al., 1997; Guo et al., 1999; Guo et al., 1996). Mines and inland salt springs being scarce and often located in hostile areas like the Dead Sea or the salt mines in the Sahara desert, they required well-organised security for transport, storage and highly monopolised distribution. Several experiments have shown that opioid receptor antagonists applied directly to the brain block the antinociceptive effects of N₂O, but these drugs have no effect when injected into the spinal cord. A combination of strong sunshine and low humidity or an extension of peat marshes was necessary for winning salt from the sea - the most plentiful source - by solar evaporation or boiling. Drugs which inhibit the breakdown of endogenous opioids also potentiate the antinociceptive effects of N₂O (Branda et al., 2000). Until common salt (sodium chloride) was mined in quantity in comparatively recent times, its availability was subject to the vagaries of climate and environment. Administration of antibodies which bind and block the activity of some endogenous opioids (not beta-endorphin) block the antinociceptive effects of N₂O (Branda et al., 2000; Cahill et al., 2000).

When AT&T was broken up into the "Baby Bell" components, MCI, Sprint, and other companies were able to compete effectively in the long-distance phone market and started to take phone traffic from the less efficient AT&T. When animals are given morphine chronically they develop tolerance to its antinociceptive (pain killing) effects; this also renders the animals tolerant to the antinocicpetive effects of N₂O (Berkowitz et al., 1979). AT&T and Standard Oil are debatable examples of the breakup of a private monopoly. Most interestingly, the effects of N₂O seem somehow linked to the interaction between the endogenous opioid system and the descending noradrenergic system. Public utilities, often being natural monopolies and less susceptible to efficient breakup, are often strongly regulated or publicly-owned. Indeed, in humans given 30% N₂O, benzodiazepine receptor antagonists reduced the subjective reports of feeling “high”, but did not alter psycho-motor performance (Zacny et al., 1995). (This is a rather optimistic view of how effectively regulation can substitute for competition.) When monopolies are not broken through the open market, often a government will step in to either regulate the monopoly, turn it into a publicly-owned monopoly, or forcibly break it up (see Antitrust law). Mirroring this, animals which have developed tolerance to the anxiolytic effects of benzodiazepines are partially tolerant to nitrous oxide (Czech & Green, 1992; Emmanouil et al., 1994; Quock et al., 1992).

Some argue that it can be good to allow a firm to attempt to monopolize a market, since practices such as dumping can benefit consumers in the short term; and once the firm grows too big, it can then be dealt with via regulation. This anti-anxiety effect is partially reversed by benzodiazepine receptor antagonists. For example, a canal monopoly in the late eighteenth century United Kingdom was worth a lot more than in the late nineteenth century, because of the introduction of railways as a substitute. In many behavioral tests of anxiety, low doses of N₂O is a successful anxiolytic. It might also be because of the availability in the longer-term of substitutes in other markets. Unlike most general anesthetics, N₂O seems to somehow affect the benzodiazepine receptor. This is likely to happen where a market's barriers to entry are low. Unlike many anesthetics, however, N₂O does not seem to affect calcium channels (Mennerick et al., 1998).

The theory of contestable markets argues that in some circumstances (private) monopolies are forced to behave as if there were competition, because of the risk of losing that monopoly to new entrants. These channels are largely responsible for keeping neurons at the resting (unexcited) potential (Gruss et al., 2004). Sometimes this very loss of efficiency can raise the potential value of a competitor enough to overcome market entry barriers, or provide incentive for research and investment into new alternatives. N₂O, like other volatile anesthetics, activates twin-pore potassium channels, albeit weakly. It is also often argued that monopolies tend to become less efficient and innovative over time, becoming "complacent giants", because they don't have to be efficient or innovative to compete in the marketplace. The evidence on the effect of N₂O on GABA-A currents is mixed, but tends to show a lower potency potentiation (Dzoljic & Van Duijn, 1998; Mennerick et al., 1998; Yamakura & Harris, 2000). However, total social welfare declines compared with perfect competition, because some consumers must choose second-best products. Like many classical anesthetics, N₂O non-competitively inhibits the NMDA receptor with high affinity and efficacy at concentrations directly proportional to its anaesthetic concentrations (Jevtovic-Todorovic et al., 1998; Mennerick et al., 1998; Yamakura & Harris, 2000).

Assuming that costs stay the same, this does not lead to an outcome which is inefficient in the sense of Pareto efficiency; no-one could be made better off by shifting resources without making someone else worse off. It is chemically inert at body temperatures, and so it is carried free in the blood rather than binding to hemogloubin. In this way the monopoly will secure monopoly profits by appropriating some or all of the consumer surplus, as although the higher price deters some consumers from purchasing, most are willing to pay the higher price. Nitrous oxide diffuses through membranes much faster than any other anesthetic gas, giving it an extremely rapid onset. In standard economic theory (see analysis above), a monopoly will sell a lower quantity of goods at a higher price than firms would in a purely competitive market. This makes it effective for propelling whipped cream and also permits the gas to quickly penetrate fatty phospholipid cell membranes. For a discussion on a monopolist who does not know it, see http://www.economicswebinstitute.org/essays/monopolist.htm where a free software is available as well. Nitrous oxide is relatively non-polar and has a low molecular weight, allowing it to dissolve through fats easily.

This procedure assumes that the monopolist knows exactly which is the demand function. Nitrous oxide shares many pharmacological similarities with classical gaseous and intravenous anesthetics, however, there are well-documented unquestionable differences. (the rate of marginal revenue is less than the rate of marginal cost, for maximisation). However, such auto-grade nitrous oxide is mixed with hydrogen sulfide and would cause significant deleterious effects if inhaled. marginal revenue = marginal cost, provided. There have been numerous reported instances of police officers arresting drivers of vehicles equipped with nitrous oxide injection systems on the grounds that he or she intends to inhale it. i.e. Some localities also require certified system components.

Setting this equal to zero for maximisation:. Nitrous oxide injection systems for automobiles are usually legal, although the use of a nitrous oxide system is likely to result in speeds that are in violation of other traffic laws. Taking the first order derivative with respect to quantity yields:. Possession of nitrous oxide is illegal in most localities in the United States for the purposes of inhaling or ingesting if not under the care of a physician or dentist. Hence its profit is:. Human activity is thought to account for somewhat less than 2 teragrams (this is multiplied by appx 300 when calculated as a ratio to Carbon Dioxide) of nitrogen oxides per year, nature for over 15 teragrams [2]. The monopoly's revenue is the product of the price and the quantity it produces. Human activity contributes to the release of the gas through the cultivation of soil and the production and use of nitrogen fertilizers, the production of nylon, and the burning of fossil fuels and other organic matter.

Let the price it sets as a market response be a function of the quantity it produces (Q) P(Q) and let its cost function be as a function of quantity C(Q). Nitrous oxide is naturally emitted from soils and oceans. The monopoly's profit is its total revenue less its total cost. Behind carbon dioxide and methane, nitrous oxide is the third most important gas that contribute to global warming. The single price monopoly profit maximisation problem is as follows:. Therefore, nitrogen oxides are a subject of efforts to curb greenhouse gas emissions, such as the Kyoto Protocol. This difference is known as a deadweight loss. Nitrogen oxides, nitrous oxide included, are greenhouse gases; per kilogram, nitrous oxide has 296 times the effect of carbon dioxide for producing global warming [1].

The economy as a whole loses out when monopoly power is used in this way, since the extra profit earned by the firm will be smaller than the loss in consumer surplus. Contamination with fuels has been implicated in a handful of rocketry accidents, where small quantities of nitrous / fuel mixtures detonated, triggering the explosive decomposition of residual nitrous oxide in plumbing. A formula gives the relation between price, marginal cost of production and demand elasticity which maximizes a monopoly profit: (known as Lerner Index). Liquid nitrous oxide acts a good solvent for many organic compounds; liquid mixtures can form somewhat sensitive explosives. With an increase of the price the price elasticity tends to rise, and in the optimum mentioned above it will for most customers be above one. While normally inert in storage and fairly safe to handle, nitrous oxide can decompose energetically and potentially detonate if initiated under the wrong circumstances. As long as the price elasticity of demand (in absolute value) for most customers is less than one, it is very advantageous to increase the price: the seller gets more money for less goods. The major safety hazards of nitrous oxide come from the fact that it is a compressed liquified gas, and a dissociative anaesthetic.

The profit the monopoly gains is the shaded in area labeled profit. It is very important with nitrous oxide augmentation of internal combustion engines to maintain temperatures and fuel levels so as to prevent preignition, or detonation (sometimes referred to as knocking, pinging or pinking). This is above the competitive price of Pc and with a smaller quantity than the competitive quantity of Qc. See nitrous. This will be at the quantity Qm; and at the price Pm;. You will find Dry kits, Wet kits & Direct port. This can be seen on a supply and demand diagram for the firm. Nitrous kits such as such as NOS, Nitrous Express, Nitrous Direct brands offer different solutions.

If a monopoly can only set one price it will set it where marginal cost (MC) equals marginal revenue (MR) as seen on the diagram on the right. There are several ways of introducing nitrous into a motor. In a pure monopoly market, only the latter effect is at work, and so, particularly for inflexible commodities such as medical care, the drop in units sold as prices rise may be much less dramatic than one might expect. Power increases of 100-300% are possible, and unless the mechanical structure of the engine is reinforced, most engines would not survive this kind of operation. In most real markets, the drop in demand associated with a price increase is due partly to losing customers to other sellers and partly to customers who are no longer willing or able to buy the product. One of the major problems of using nitrous oxide in a reciprocating engine is that it can produce enough power to destroy the engine. If they set it lower, they sell more. Accordingly, it was only used by specialized planes like high-altitude reconnaissance aircraft, high-speed bombers and high-altitude interceptors.

If they set it higher, they sell less. Originally meant to provide the Luftwaffe standard aircraft with superior high-altitude performance, technological considerations limited its use to extremely high altitudes. In contrast, a business with monopoly power can choose the price they want to sell at. The same technique was used during by World War II Luftwaffe aircraft with the GM 1 system to boost the power output of aircraft engines. A price taker cannot choose the price that they sell at, since if they set it above the equilibrium price, they will sell none, and if they set it below the equilibrium price, they will have an infinite number of buyers (and be making less money than they could if they sold at the equilibrium price). This results in a smaller, denser charge, and can reduce detonation, as well as increase power available to the engine. This is in contrast to a price taker that faces a horizontal demand curve. Additionally, since nitrous oxide is stored as a liquid, the evaporation of liquid nitrous oxide in the intake manifold causes a large drop in intake charge temperature.

In economics a company is said to have monopoly power if it faces a downward sloping demand curve (see supply and demand). In car racing, nitrous oxide (often just "nitrous" in this context) is sometimes injected into the intake manifold (or just prior to the intake manifold) to increase power: even though the gas itself is not flammable, it delivers more oxygen than atmospheric air by breaking down at elevated temperatures, thus allowing the engine to burn more fuel and air. The term is typically used by those who favor laissez-faire capitalism. An episode of MythBusters featured a hybrid rocket built using paraffin wax mixed with powdered carbon as its solid fuel and nitrous oxide as its oxidizer. A coercive monopoly is one that arises and whose existence is maintained as the result of any sort of activity that violates the principle of a free market and is therefore insulated from competition which would otherwise be a potential threat to its superior status. It is also notably used in amateur and high power rocketry with various plastics as the fuel. Main article: coercive monopoly. The combination of nitrous oxide with hydroxy-terminated polybutadiene fuel has been used by SpaceShipOne and others.

A common example is vertical integration of electricity distribution with electricity generation, which is common because it reduces or eliminates certain costly risks. Nitrous oxide has notably been the oxidizer of choice in several hybrid rocket designs (using solid fuel with a liquid or gaseous oxidizer). A monopoly arrived at through vertical integration is called a vertical monopoly. This has the advantages over other oxidizers that it is non-toxic and, due to its stability at room temperature, easy to store and relatively safe to carry on a flight. A magazine publishing firm, for example, might publish many different magazines on many different subjects, but it would still be considered to engage in monopolistic practices if the intent of doing this was to control the entire magazine-reader market, and prevent the emergence of competitors. Nitrous oxide can be used as an oxidizer in a rocket engine. Such a monopoly is known as a horizontal monopoly. There is also usually a negligible amount of N2O in the cans.

Large corporations often attempt to monopolize markets through horizontal integration, in which a parent company consolidates control over several small, seemingly diverse companies (sometimes even using different branding to create the illusion of marketplace competition). However, if one is using the Nitrous for recreational purposes, using N2O straight from a whipped cream can is unadvisable due to the fact that it is frequently cut with certain chemicals that can cause headaches or nausea. Practices which these entities may be accused of include dumping products below cost to harm competitors, creating tying arrangements between their products, and other practices regulated under antitrust law. One can easily obtain the propellant by slowly turning the canister upside down (NO SHAKING) and letting all the contents out, leaving you the N2O. Common historical examples arguably include corporations such as Microsoft and Standard Oil (Standard's market share of refining was 64% in competition with over 100 other refiners at the time of the trial that resulted in the government-forced breakup). In aerosol whipped cream, it is dissolved in the fatty cream until it leaves the can, when it becomes gaseous and thus creates foam. Industries which are dominated by a single firm may allow the firm to act as a near-monopoly or "de facto monopoly", a practice known in economics as monopolistic competition. The gas is excellently soluble in fatty compounds.

Main article: Monopolistic competition. Its most common uses in this context are in aerosol whipped cream canisters and as an inert gas used to displace staleness-inducing oxygen when filling packages of potato chips and other similar snack foods. This may include the ability to charge (to some extent) monopoly pricing, for example in the case of the only gas station on an expressway rest stop, which will serve a certain number of motorists who lack fuel to reach the next station and must pay whatever is charged. The gas is licensed for use as a food additive, specifically as an aerosol spray propellant. A local monopoly is a monopoly of a market in a particular area, usually a town or even a smaller locality: the term is used to differentiate a monopoly that is geographically limited within a country, as the default assumption is that a monopoly covers the entire industry in a given country. Nitrous Oxide is liquid at approximately 760 psi at room temperature, and is usually stored and shipped as a self-pressurized liquid. They say that the idea of "natural monopoly" is mere theoretical abstraction to justify expanding the scope of government, and that, in the case of nationalization or deprivatization, it is the government intervention itself that creates a monopoly where one did not actually exist. Less than 0.004% is metabolised in humans.

Advocates of free markets, such as libertarians, assert that a natural monopoly is a practical impossibility, and, given that a monopoly is a persistent rather than a transient situation, that there is no historical precedent of one ever existing. It has a MAC of 105% and a blood:gas partition coefficient of 0.46. A natural monopoly industry can also be artificially broken up by government, although (eg electricity liberalization, eg Railtrack) the results are at best mixed. Its lower solubility in blood means it has a very rapid onset and offset. Whether an industry is a natural monopoly may change over time through the introduction of new technologies. In general anesthesia it is often used in an 2:1 ratio with oxygen in addition to more powerful general anaesthetic agents such as sevoflurane or desflurane. Counter-intuitively, the case of a monopolization of a key source of a natural resource is not considered a natural monopoly, because it is based on the running down of natural capital rather than the amortization of an investment in physical or human capital. However, it has a very low short-term toxicity and is an excellent analgesic, so a 50/50 mixture of nitrous oxide and oxygen ("gas and air", supplied under the trade name Entonox) is commonly used during childbirth, for dental procedures, and in emergency medicine.

It should be distinguished from network effects, which operate on the demand side and do not affect costs. the nitrous oxide is a very strong analgesic and a week mixture o it with oxygen is used in operation.n NOTE""""----IT does not produce laughing fits-------"""""" general anesthetic, and is generally not used alone in anaesthesia. Natural monopoly arises when there are large capital costs relative to variable costs, which arises typically in network industries such as electricity and water. Finally, nitrous oxide should not be confused with nitric oxide, an extremely poisonous gas. In these industries monopoly may be more economically efficient than competition, although because of potential dynamic efficiencies this is not necessarily clear-cut. Inhaling industrial-grade nitrous oxide is also dangerous, as it contains many impurities and is not intended for use on humans. In these industries competition will tend to be eliminated as the largest (often the first) firm develops a monopoly through its cost advantage. It can be habit-forming, mainly because of its short-lived effect (generally from 1 - 5 minutes in recreational doses) and ease of access.

A natural pool is a monopoly that arises in industry where economies of scale are so large that a single firm can supply the entire market without exhausting them. In chronic use it is also teratogenic, and foetotoxic. Main article: Natural monopoly. Long-term use in large quantities has been associated with dangerous symptoms similar to vitamin B12 deficiency: anemia due to reduced hemopoiesis, neuropathy, tinnitus, and numbness in extremities. It is not the result of government granted privilege, subsidies, regulations, etc. While the pure gas itself is not toxic, death can result if it is inhaled in such a way that not enough oxygen is breathed in. An efficiency monopoly is one that exists because a firm is satisfying consumer demand so well that profitable competition is extremely challenging. For those reasons, most recreational nitrous oxide users will discharge the gas into a balloon before inhaling.

An example of a "de jure" monopoly is AT&T, which was granted monopoly power by the US government, only to be broken up in 1982 following a Sherman Antitrust suit. Inhalation of nitrous oxide directly from a whipped cream charger or a tank poses serious health risks, as it can cause the lungs to collapse from high levels of pressure, forcing air into the chest cavity, and can cause frostbite since the gas is very cold when released. A government monopoly may exist at different levels of government (eg just for one region or locality); a state monopoly is specifically operated by a national government. Since nitrous oxide can cause dizziness, dissociation, and temporary loss of motor control, it is unsafe to inhale while standing up. When such a monopoly is granted to a private party, it is a government-granted monopoly; when it is operated by government itself, it is a government monopoly or state monopoly. 381b.) The Centre for Cognitive Liberty and Ethics, a nonprofit law and policy center in the United States, contends that such laws are unconstitutional "prior restraints on speech" and constitute "cognitive censorship.". A monopoly based on laws explicitly preventing competition is a legal monopoly or de jure monopoly. Code, Sec.

sole access to a resource, economies of scale, or consistently outcompeting all other firms. Pen. Monopolies are often distinguished based on the circumstances under which they arise; the broadest distinction is between monopolies that are the result of government intervention and those that arise without it e.g. In California, for instance, inhalation of nitrous oxide "for the purpose of causing euphoria, or for the purpose of changing in any manner, one’s mental processes," is a criminal offense under its criminal code Cal. . The recreational use of nitrous oxide is restricted in many districts. In a monopoly a single firm is the sole provider of a product or service; in a cartel a centralized institution is set up to partially coordinate the actions of several independent providers (which is a form of oligopoly). One slang term for the drug is Hippie Crack; this term implies commentary on the typical user of the substances as well as purported similarities between its psychological addiction potential or the short-lived duration of its effects and similar properties of "crack" cocaine.

Monopoly should be distinguished from monopsony, in which there is only one buyer of the product or service; it should also, strictly, be distinguished from the (similar) phenomenon of a cartel. It was often sold at Grateful Dead and Phish concerts. Monopolies are characterized by a lack of economic competition for the good or service that they provide and a lack of viable substitute goods. The drug currently enjoys moderate popularity in the United States psychedelic community as an inhalant. In economics, a monopoly (from the Greek monos, one + polein, to sell) is defined as a persistent market situation where there is only one provider of a kind of product or service. Memory of this experience, however, quickly faded and any attempt to communicate was difficult at best. Blocked Entry. James claimed to experience the fusing of dichotomies into a unity and a revelation of ultimate truth during the inhalation of nitrous oxide.

Price Maker. During the 19th century, William James and many contemporaries found that inhalation of nitrous oxide resulted in a powerful spiritual and mystical experience for the user. No Close Substitutes. It can also result in mild nausea or lingering dizziness if too much is inhaled in too short a time. Single Seller. Nitrous oxide (N₂O) is a dissociative that can cause analgesia, euphoria, dizziness, flanging of sound, and, in some cases, slight hallucinations and mild aphrodisiac effect. And so it came into use as an anaesthetic, particularly by dentists, who do not typically have access to the services of an anesthesiologist and who may benefit from a patient who can respond to verbal commands.

They soon realised that nitrous oxide considerably dulled the sensation of pain, even if the inhaler were still semi-conscious. Humphry Davy in the 1790s tested the gas on himself and some of his friends, including the poets Samuel Taylor Coleridge and Robert Southey. The gas was discovered by Joseph Priestley in 1772. The CAS number of nitrous oxide is 10024-97-2 and its UN number is 1070.

Nitrous oxide can be used to nitrites by mixing it with boiling alkali metals, and to oxidize organic compounds at high temperatures. Nitrous oxide can be prepared by heating ammonium nitrate in the laboratory. Note that nitrous oxide is isoelectric with carbon dioxide. Nitrous oxide [[N₂O]] should not be confused with the other nitrogen oxides such as nitric oxide NO and nitrogen dioxide NO₂.

It can be considered a resonance hybrid of. The structure of the nitrous oxide molecule is a linear chain of a nitrogen atom bound to a second nitrogen, which in turn is bound to an oxygen atom. . Nitrous oxide is present in the atmosphere where it acts as a powerful greenhouse gas.

It is used in surgery and dentistry for its anaesthetic and analgesic effects. It is commonly known as laughing gas due to the exhilarating effects of inhaling it, and because it can cause spontaneous laughter in some people; it's also known as NOS or nitrous in racing and motorsports, where its usage is widespread. Under room conditions, it is a colourless non-flammable gas, with a pleasant, slightly-sweet odor. Nitrous oxide, also known as dinitrogen oxide or dinitrogen monoxide, is a chemical compound with chemical formula N₂O.

In the Munsters episode where Herman sneaks into the hospital to visit Eddie after hours, Herman is given Laughing Gas by the staff. In Black Sheep, the two main protagonists borrow a police car and its nitrous oxide boosters leak after hitting a pothole, intoxicating the duo. The main character of Zodiac, Sangamon Taylor, uses it as a drug, and even came up with Sangamon's Principle to explain why it should be used over other drugs. Two of the main characters in Taxi get trapped in a room filled with laughing gas.

One of the main characters in the musical film version of Little Shop of Horrors dies from the inhalation of Laughing Gas. Laughing Gas is one of the main weapons used by the Batman villain, The Joker, only he uses a concoction which is portrayed as being green and lethal. Laughing Gas (novel). Laughing Gas (movie).
