When an economist says that the demand for a product
Laws and regulations often include a safe harbour clause that sets out the circumstances in which otherwise regulated firms or individuals can do something without regulatory oversight or ng for what is good enough, rather than the best that is possible. Classical economics and neo-classical economics assume that individuals, firms and governments try to achieve the optimum, best possible outcome from their decisions. Satisficing assumes they decide for each goal a level of achievement that would be good enough and try to find a way to achieve all of these sub-optimal goals at once. The concept was invented by herbert simon (1916-2001), a nobel prize-winning economist, in his book, models of man, in income that is not spent. At times when the demand for financial securities is unusually high, this can give a misleading impression of how much saving is taking much individuals save varies significantly among different age groups (see life-cycle hypothesis) and nationalities. The supply of savings rises when interest rates rise; a rise in interest rates causes demand for funds to invest to fall; a rise in demand for investment funds may cause interest rates, and thus the cost of capital, to rise. The level of savings is also influenced by changes in wealth (see wealth effect) and by taxation creates its own demand. So argued a french economist, jean-baptiste say (1767-1832), and many classical and neo-classical economists since. Keynes argued against say, making the case for the use of fiscal policy to boost demand if there is not enough of it to produce full ease with which the supply of an economic product or process can be expanded to meet increased demand. Recent technological advances have led some economists to talk about the growing importance of instant scalability. This potentially allows a new product to enter and win market share far more quickly than ever before, intensifying competition and perhaps accelerating the process of creative destruction (see schumpeter). In economic terms, it means simply that needs and wants exceed the resources available to meet them, which is as common in rich countries as in poor g your plans against various possible scenarios to see what might happen should things not go as you hope. Scenario analysis is an important technique in risk management, helping firms and especially financial institutions to ensure that they do not take on too much risk. Finding what you want and ensuring that it is competitively priced can be expensive, be it the financial cost of physically getting to a marketplace or the opportunity cost of time spent fact-finding. Search costs mean that people often take decisions without all the relevant information, which can result in inefficiency. To reveal underlying trends, statistics reflecting only part of the year are often adjusted to iron out seasonal we do not live in a perfect world, how useful are economic theories based on the assumption that we do? Second-best theory, set out in 1956 by richard lipsey and kelvin lancaster (1924-99), looks at what happens when the assumptions of an economic model are not fully met. They found that in situations where not all the conditions are met, the second-best situation - that is, meeting as many of the other conditions as possible - may not result in the optimum solution. Indeed, reckoned lipsey and lancaster, in general, when one optimal equilibrium condition is not satisfied all of the other equilibrium conditions will ially, the second-best equilibrium may be worse than a new equilibrium brought about by government intervention, either to restore equilibrium to the market that is in disequilibrium, or to move the other markets away from their second-best ists have seized on this insight to justify all sorts of interventions in the economy, ranging from taxing certain goods and subsidising others to restricting free trade. Whenever there is market failure, second-best theory says it is always possible to design a government policy that would increase economic welfare. Alas, the history of government intervention suggests that although the second best may be improved on in theory, in practice second best is often least worst. The existence of liquid secondary markets can encourage people to buy in the primary market, as they know they are likely to be able to sell easily should they ial contracts, such as bonds, shares or derivatives, that grant the owner a stake in an asset. Issuers gain instant access to money for which they would otherwise have to wait months or years, and they can shed some of the risk that their expected revenue will not materialise. Some economists argue that introducing the right policies alone is not enough to revive a malfunctioning economy; reforms must be implemented in the right sequence. Thus they debate when in the reform process there should be, say, privatisation of state enterprises, and in which order, or the lifting of capital controls or other trade barriers. Other economists dispute whether there is a right ts of economic activity that you can’t drop on your foot, ranging from hairdressing to websites. Shadow prices can be calculated for those goods and services that do not have a market price, perhaps because they are set by government. Shadow pricing is often used in cost-benefit analysis, where the whole purpose of the analysis is to capture all the variables involved in a decision, not merely those for which market prices g shareholders first; the notion that all business activity should aim to maximise the total value of a company’s shares. Some critics argue that concentrating on shareholder value will be harmful to a company’s other stakeholders, such as employees, suppliers and ial securities, each granting part ownership of a company. The higher the sharpe ratio is the better, that is, the greater is the return per unit of risk. However, as it is a backward-looking measure, based on what an investment has done in the past, the sharpe ratio does not guarantee similar performance in unexpected event that affects an economy (see asymmetric shock). Things that make you better off in the short-run but worse off in the end. As a result, managers did things that made their profits look as good as possible in the short run, often to the detriment of their company's long-term health. In the 1980s and early 1990s, the complaint took a slightly different form, and was arguably less convincing, namely that short-termism caused lower levels of investment by businesses than in countries where the stockmarket was less important, such as germany and g a security, such as a share, that you do not currently own, in the expectation that its price will fall by the time the security has to be delivered to its new owner. Often the biggest problem facing sellers is how to convince buyers that what they are selling is as good as they say it is. This problem arises in situations where the qualities of the thing being sold cannot be observed easily by buyers, who thus fear that sellers may be conning them. In such situations, an answer may be for sellers to do something that shows they mean what they say about quality. This something is what economists call to a leading university might be worth far more for what it signals to prospective employers about your abilities than for what you learn as a student.
Likewise, the fact that a firm is willing to spend a lot of money advertising its product may say far more about what it thinks of the product than any information included in the actual ad. Social benefits/costs are the sum of private benefits/costs arising from the activity and any amount of community spirit or trust that an economy has gluing it together. Yet, curiously, one of the best-known books to address the role of social capital, "bowling alone", by robert putnam of harvard university, pointed out that americans were far less likely to be members of community organisations, clubs or associations in the 1990s than they were in the 1950s. This has led some economists to question whether social capital is really as important as the theory suggests, and others to argue that membership of bowling leagues and other community organisations is simply not a good indicator of the amount of social capital in a name given to the economic arrangements devised in germany after the second world war. More broadly, it refers to the study of the different social institutions underpinning every market exact meaning of socialism is much debated, but in theory it includes some collective ownership of the means of production and a strong emphasis on equality, of some sort.

Soft loans are used by international agencies to encourage economic activity in developing countries and to support non-commercial risk that a government will default on its debt or on a loan guaranteed by attitude to investment that is often criticised. This benefits longer-term investors, too, as it enables them to get a good price when they do eventually precautionary price quoted for a transaction that is to be made on the spot, that is, paid for now for delivery now. Yield on two different ment policies intended to smooth the economic cycle, expanding demand when unemployment is high and reducing it when inflation threatens to increase. For instance, social handouts from the state usually increase during tough times, and taxes increase (fiscal drag), boosting government revenue, when the economy is ity and growth ary rules agreed to by euro zone countries as a condition of joining the euro. The pact stipulates that all the countries will run a balanced budget in normal times. A government that runs a fiscal deficit bigger than 3% of gdp must take swift corrective action. The pact was supposed to be a powerful political symbol that euro-using countries would not cheat each other. When, in 2002, france and germany also exceeded the 3% limit, some eu members were outraged and others lobbied for the pact to be modified or even coined in the 1970s for the twin economic problems of stagnation and rising inflation. Indeed, policymakers believed the message of the phillips curve: that unemployment and inflation were alternatives. Prolonged recession, but not as severe as a the parties that have an interest, financial or otherwise, in a company, including shareholders, creditors, bondholders, employees, customers, management, the community and government. How these different interests should be catered for, and what to do when they conflict, is much debated. In particular, there is growing disagreement between those who argue that companies should be run primarily in the interests of their shareholders, in order to maximise shareholder value, and those who argue that the wishes of shareholders should sometimes be traded off against those of other stakeholders. The most commonly used measure of statistical significance is that there must be a 95% chance that the result is right and only a 1 in 20 chance of the result occurring ised a government or central bank buys or sells some of its reserves of foreign currency this can affect the country’s money supply. Governments or central banks can sterilise (that is, cancel out) this effect of foreign exchange intervention on the money supply by buying or selling an equivalent amount of securities. Prices change only when the cost of leaving them unchanged exceeds the expense of adjusting them. It is also another word for inventories of goods held by a firm to meet future demand. Structural unemployment can be reduced only by changing the economic structures causing it, for instance, by removing rules that limit labour market paid, usually by government, to keep prices below what they would be in a free market, or to keep alive businesses that would otherwise go bust, or to make activities happen that otherwise would not take place. By distorting markets, they can impose large economic for which an increase (or fall) in demand for one leads to a fall (or increase) in demand for the other – coca-cola and pepsi, the price of petrol falls people buy more of it. There are two income effect: cheaper petrol means that real purchasing power rises, so consumers have more to spend on everything, including substitution effect: petrol has become cheaper relative to everything else, so people switch some of their consumption out of goods that are now relatively more expensive and buy more petrol what is done cannot be undone. Sunk costs are costs that have been incurred and cannot be reversed, for example, spending on advertising or researching a product idea. If potential entrants would have to incur similar costs, which would not be recoverable if the entry failed, they may be scared of the two words economists use most, along with demand. The law of supply is that, other things remaining the same, the quantity supplied will increase as the price increases. The actual amount supplied will be determined, ultimately, by what the market price is, which depends on the amount demanded as well as what suppliers are willing to produce. What suppliers are willing to supply depends on several things:The cost of the factors of production;. Price of other goods and services (which, if high enough, might tempt the supplier to switch production to those products); ability of the supplier accurately to forecast demand and plan production to make the most of the opportunity. In the 1980s, ronald reagan and margaret thatcher championed supply-side policies as they attacked keynesian demand management. Pumping up demand without making markets work better would simply lead to higher inflation; economic growth would increase only when markets were able to operate more freely. In particular, the belief, apparently supported by the laffer curve, that cutting tax rates would increase tax revenue did not always stand up well to real-world testing. Even so, it is now recognised that supply-side reforms are a crucial element in an effective economic policy. Term much used by environmentalists, meaning economic growth that can continue in the long term without non-renewable resources being used up or pollution becoming intolerable. Mainstream economists use the term, too, to describe a rate of growth that an economy can sustain indefinitely without causing a rise in risk that remains after diversification, also known as market risk or undiversifiable risk. It is systematic risk that determines the return earned on a well-diversified portfolio of risk of damage being done to the health of the financial system as a whole.
A constant concern of bank regulators is that the collapse of a single bank could bring down the entire financial system. This is why regulators often organise a rescue when a bank gets into financial difficulties. However, the expectation of such a rescue may create a moral hazard, encouraging banks to behave in ways that increase systemic risk. Another concern of regulators is that the risk management methods used by banks are so similar that they may increase systemic risk by creating a tendency for crowd behaviour.

Of blacklisted links:Say's law, or the law of markets, in classical economics, states that aggregate production necessarily creates an equal quantity of aggregate demand. The french economist jean-baptiste say (1767–1832) introduced the idea in 1803, in his principal work, a treatise on political economy (traité d'économie politique):A product is no sooner created, than it, from that instant, affords a market for other products to the full extent of its own value. Each of us can only purchase the productions of others with his own productions – as the value we can buy is equal to the value we can produce, the more men can produce, the more they will purchase. Further argued that this law of markets implies that a general glut (the term used in say's time for a widespread excess of supply over demand) cannot occur. If there is a surplus of one good, there must be unmet demand for another: "if certain goods remain unsold, it is because other goods are not produced. 2] say's law has been one of the principal doctrines used to support the laissez-faire belief that a capitalist economy will naturally tend toward full employment and prosperity without government intervention. The years, at least two objections to say's law have been raised:General gluts do occur, particularly during recessions and ic agents may collectively choose to increase the amount of money they hold, thereby reducing demand but not 's law was generally accepted throughout the 19th century, though modified to incorporate the idea of a "boom-and-bust" cycle. Argued that economic agents offer goods and services for sale so that they can spend the money they expect to obtain. Therefore, the fact that a quantity of goods and services is offered for sale is evidence of an equal quantity of demand. This claim is often summarized as "supply creates its own demand", although that phrase does not appear in say's ning his point at length, he wrote:It is worthwhile to remark that a product is no sooner created than it, from that instant, affords a market for other products to the full extent of its own value. When the producer has put the finishing hand to his product, he is most anxious to sell it immediately, lest its value should diminish in his hands. But the only way of getting rid of money is in the purchase of some product or other. Thus the mere circumstance of creation of one product immediately opens a vent for other products. Further argued that because production necessarily creates demand, a "general glut" of unsold goods of all kinds is impossible. Further clarify, he wrote: "sales cannot be said to be dull because money is scarce, but because other products are so. S law should therefore be formulated as: supply of x creates demand for y, subject to people being interested in buying x. The producer of x is able to buy y, if his products are rejected the possibility that money obtained from the sale of goods could remain unspent, thereby reducing demand below supply. He viewed money only as a temporary medium of performs but a momentary function in this double exchange; and when the transaction is finally closed, it will always be found, that one kind of commodity has been exchanged for another. Thomas malthus and john stuart mill questioned the doctrine that general gluts cannot mill and david ricardo restated and developed say's law. Mill wrote, "the production of commodities creates, and is the one and universal cause which creates, a market for the commodities produced. Malthus, on the other hand, rejected say’s law because he saw evidence of general hear of glutted markets, falling prices, and cotton goods selling at kamschatka lower than the costs of production. It may be said, perhaps, that the cotton trade happens to be glutted; and it is a tenet of the new doctrine on profits and demand, that if one trade be overstocked with capital, it is a certain sign that some other trade is understocked. But where, i would ask, is there any considerable trade that is confessedly under-stocked, and where high profits have been long pleading in vain for additional capital? He argued that during a general glut, there is insufficient demand for all non-monetary commodities and excess demand for there is a general anxiety to sell, and a general disinclination to buy, commodities of all kinds remain for a long time unsold, and those which find an immediate market, do so at a very low price...
As there may be a temporary excess of any one article considered separately, so may there of commodities generally, not in consequence of over-production, but of a want of commercial confidence. Rescued the claim that there cannot be a simultaneous glut of all commodities by including money as one of the order to render the argument for the impossibility of an excess of all commodities applicable... It must, undoubtedly, be admitted that there cannot be an excess of all other commodities, and an excess of money at the same time. Economist brad delong believes that mill’s argument refutes the assertions that a general glut cannot occur, and that a market economy naturally tends towards an equilibrium in which general gluts do not occur. 18] the quarter of the labor force that was unemployed constituted a supply of labor for which the demand predicted by say's law did not maynard keynes argued in 1936 that say's law is simply not true, and that demand, rather than supply, is the key variable that determines the overall level of economic activity. According to keynes, demand depends on the propensity of individuals to consume and on the propensity of businesses to invest, both of which vary throughout the business cycle. Steven kates, although a proponent of say's law, writes:Before the keynesian revolution, [the] denial of the validity of say's law placed an economist amongst the crackpots, people with no idea whatsoever about how an economy works. That the vast majority of the economics profession today would have been classified as crackpots in the 1930s and before is just how it is. Economists, such as paul krugman, stress the role of money in negating say's law: money that is hoarded (held as cash or analogous financial instruments) is not spent on products. To increase monetary holdings, someone may sell products or labor without immediately spending the proceeds. To increase net savings requires earning more than is spent—contrary to say's law, which postulates that supply (sales, earning income) equals demand (purchases, requiring spending). Keynesian economists argue that the failure of say's law, through an increased demand for monetary holdings, can result in a general glut due to falling demand for goods and economists today maintain that supply does not create its own demand, but instead, especially during recessions, demand creates its own supply. Paul krugman writes:Not only doesn't supply create its own demand; experience since 2008 suggests, if anything, that the reverse is largely true -- specifically, that inadequate demand destroys supply. Economies with persistently weak demand seem to suffer large declines in potential as well as actual output. Blanchard and larry summers, observing persistently high and increasing unemployment rates in europe in the 1970s and 1980s, argued that adverse demand shocks can lead to persistently high unemployment, therefore persistently reducing the supply of goods and services. 22] antonio fatás and larry summers argued that shortfalls in demand, resulting both from the global economic downturn of 2008 and 2009 and from subsequent attempts by governments to reduce government spending, have had large negative effects on both actual and potential world economic output. Some proponents of the heterodox austrian school of economics maintain that the economy tends to full-employment equilibrium, and that recessions and depressions are the result of government intervention in the economy. 24] some proponents of real business cycle theory maintain that high unemployment is due to a reduced labor supply rather than reduced demand. In other words, people choose to work less when economic conditions are poor, so that involuntary unemployment does not actually exist. He argued that the power to purchase can only be increased through more mill used say's law against those who sought to give the economy a boost via unproductive consumption. In his view, consumption destroys wealth, in contrast to production, which is the source of economic growth. The demand for a product determines the price of the ing to keynes (see more below), if say's law is correct, widespread involuntary unemployment (caused by inadequate demand) cannot occur. Classical economists in the context of say's law explain unemployment as arising from insufficient demand for specialized labour—that is, the supply of viable labour exceeds demand in some segments of the more goods are produced by firms than are demanded in certain sectors, the suppliers in those sectors lose revenue as result. This loss of revenue, which would in turn have been used to purchase other goods from other firms, lowers demand for the products of firms in other sectors, causing an overall general reduction in output and thus lowering the demand for labour. This results in what contemporary macroeconomics call structural unemployment, the presumed mismatch between the overall demand for labour in jobs offered and the individual job skills and location of labour. This differs from the keynesian concept of cyclical unemployment, which is presumed to arise because of inadequate aggregate economic losses and unemployment were seen by some economists, such as marx and keynes himself, as an intrinsic property of the capitalist system. S law did not posit that (as per the keynesian formulation) "supply creates its own demand". 28] nor was it based on the idea that everything that is saved will be exchanged. Rather, say sought to refute the idea that production and employment were limited by low consumption. Say's law, in its original concept, was not intrinsically linked nor logically reliant on the neutrality of money (as has been alleged by those who wish to disagree with it[29]), because the key proposition of the law is that no matter how much people save, production is still a possibility, as it is the prerequisite for the attainment of any additional consumption goods. Say's law states that in a market economy, goods and services are produced for exchange with other goods and services—"employment multipliers" therefore arise from production and not exchange alone—and that in the process a sufficient level of real income is created to purchase the economy's entire output, due to the truism that the means of consumption are limited ex vi termini by the level of production. That is, with regard to the exchange of products within a division of labour, the total supply of goods and services in a market economy will equal the total demand derived from consumption during any given time period. In modern terms, "general gluts cannot exist",[30] although there may be local imbalances, with gluts in some markets balanced out by shortages in heless, for some neoclassical economists,[31] say's law implies that economy is always at its full employment level. This is not necessarily what say the keynesian interpretation,[31] the assumptions of say's law are:A barter model of money ("products are paid for with products");. Prices—that is, all prices can rapidly adjust upwards or downwards; government these assumptions, say's law implies that there cannot be a general glut, so that a persistent state cannot exist in which demand is generally less than productive capacity and high unemployment results. Keynes, in his general theory, argued that a country could go into a recession because of "lack of aggregate demand". Taking the assumptions in turn:Circuitists and some post-keynesians dispute the barter model of money, arguing that money is fundamentally different from commodities and that credit bubbles can and do cause depressions. Notably, the debt owed does not change because the economy has argued that prices are not flexible; for example, workers may not take pay cuts if the result is starvation.
Argue that government intervention is the cause of economic crises, and that left to its devices, the market will adjust for the implication that dislocations cannot cause persistent unemployment, some theories of economic cycles accept say's law and seek to explain high unemployment in other ways, considering depressed demand for labour as a form of local dislocation. For example, advocates of real business cycle theory[citation needed] argue that real shocks cause recessions and that the market responds efficiently to these real economic krugman dismisses say's law as, "at best, a useless tautology when individuals have the option of accumulating money rather than purchasing real goods and services. Is not easy to say what exactly say's law says about the role of money apart from the claim that recession is not caused by lack of money. The phrase "products are paid for with products" is taken to mean that say has a barter model of money; contrast with circuitist and post-keynesian monetary can read say as stating simply that money is completely neutral, although he did not state this explicitly, and in fact did not concern himself with this subject. Say's central notion concerning money was that if one has money, it is irrational to hoard it. Robertson, in his 1892 book, the fallacy of saving,[33][34] where he called say's law:A tenacious fallacy, consequent on the inveterate evasion of the plain fact that men want for their goods, not merely some other goods to consume, but further, some credit or abstract claim to future wealth, goods, or services. Robertson identifies his critique as based on say's theory of money: people wish to accumulate a "claim to future wealth", not simply present goods, and thus the hoarding of wealth may be say, as for other classical economists, it is possible for there to be a glut (excess supply, market surplus) for one product alongside a shortage (excess demand) of others. Keynesian terms, followers of say's law would argue that on the aggregate level, there is only a transactions demand for money. Money is held for spending, and increases in money supplies lead to increased classical economists did see that a loss of confidence in business or a collapse of credit will increase the demand for money, which will decrease the demand for goods. Citation needed] this would lead demand and supply to move out of phase and lead to an economic downturn in the same way that miscalculation in productions would, as described by william h. In this view, persistent depressions, such as that of the 1930s, are impossible in a free market organized according to laissez-faire principles. The flexibility of markets under laissez faire allows prices, wages, and interest rates to adjust so as to abolish all excess supplies and demands; however, since all economies are a mixture of regulation and free-market elements, laissez-faire principles (which require a free market environment) cannot adjust effectively to excess supply and a theoretical point of departure[edit]. Whole of neoclassical equilibrium analysis implies that say's law in the first place functioned to bring a market into this state: that is, say's law is the mechanism through which markets equilibrate uniquely. Ultimately, from say's law they deduced vastly different conclusions regarding the functioning of capitalist former, not to be confused with "new keynesian" and the many offsprings and syntheses of the "general theory", take the fact that a commodity–commodity economy is substantially altered once it becomes a commodity–money–commodity economy, or once money becomes not only a facilitator of exchange (its only function in marginalist theory) but also a store of value and a means of payment. What this means is that money can be (and must be) hoarded: it may not re-enter the circulatory process for some time, and thus a general glut is not only possible but, to the extent that money is not rapidly turned over, probable. Response to this in defense of say's law (echoing the debates between ricardo and malthus, in which the former denied the possibility of a general glut on its grounds) is that consumption that is abstained from through hoarding is simply transferred to a different consumer—overwhelmingly to factor (investment) markets, which, through financial institutions, function through the rate of ' innovation in this regard was twofold: first, he was to turn the mechanism that regulates savings and investment, the rate of interest, into a shell of its former self (relegating it to the price of money) by showing that supply and investment were not independent of one another and thus could not be related uniquely in terms of the balancing of disutility and utility. Through this identification, keynes deduced the consequences for the macroeconomy of long-run equilibrium being attained not at only one unique position that represented a "pareto optima" (a special case), but through a possible range of many equilibria that could significantly under-employ human and natural resources (the general case). In marx's theory, there is a gap between the creation of surplus value in production and the realization of that surplus value via a sale. To realize a sale, a commodity must have a use value for someone, so that they purchase the commodity and complete the cycle m–c–m'. The capitalist has no control over whether or not the value contained in the product is realized through the market mechanism. As the realization of capital is only possible through a market, marx criticized other economists, such as david ricardo, who argued that capital is realized via production. Moreover, the theoretical core of the marxian framework contrasts with that of the neoclassical and austrian tually, the distinction between keynes and marx is that for keynes the theory is but a special case of his general theory, whereas for marx it never existed at interpretations[edit]. Modern way of expressing say's law is that there can never be a general glut. Instead of there being an excess supply (glut or surplus) of goods in general, there may be an excess supply of one or more goods, but only when balanced by an excess demand (shortage) of yet other goods. Thus, there may be a glut of labor ("cyclical" unemployment), but this is balanced by an excess demand for produced goods. The exception is when governments or other non-market forces prevent price ing to keynes, the implication of say's law is that a free-market economy is always at what keynesian economists call full employment (see also walras' law). Thus, say's law is part of the general world view of laissez-faire economics—that is, that free markets can solve the economy's problems automatically. Increased government purchases of goods (or lowered taxes) merely "crowd out" the production and purchase of goods by the private sector. Contradicting this view, arthur cecil pigou, a self-proclaimed follower of say's law, wrote a letter in 1932 signed by five other economists (among them keynes) calling for more public spending to alleviate high levels of versus say[edit]. Summarized say's law as "supply creates its own demand", or the assumption "that the whole of the costs of production must necessarily be spent in the aggregate, directly or indirectly, on purchasing the product" (from chapter 2 of his general theory). An early example was jacob viner, who in his 1936 review of the general theory said of hoarding that keynes ‘attaches great importance to it as a barrier to “full” employment’ (p152) while denying (pp158f) that it was capable of having that effect[37]. However, keynes and others argued that hoarding decisions are made by different people and for different reasons than are decisions to dis-hoard, so that hoarding and dis-hoarding are unlikely to be equal at all times, as indeed they are not. Have argued that financial markets, and especially interest rates, could adjust to keep hoarding and dis-hoarding equal, so that say's law could be maintained, or that prices could simply fall, to prevent a decrease in production. But keynes argued that to play this role, interest rates would have to fall rapidly, and that there are limits on how quickly and how low they can fall (as in the liquidity trap, where interest rates approach zero and cannot fall further). To keynes, in the short run, interest rates are determined more by the supply and demand for money than by saving and investment. Before interest rates can adjust sufficiently, excessive hoarding causes the vicious circle of falling aggregate production (recession). The recession itself lowers incomes so that hoarding (and saving) and dis-hoarding (and real investment) can reach a state of balance below full , a recession would hurt private real investment—by hurting profitability and business confidence—through what is called the accelerator effect.
