Quantitative easing
Quantitative easing (QE) is a monetary policy whereby a central bank purchases predetermined amounts of government bonds or other financial assets (e.g., municipal bonds, corporate bonds, stocks, etc.) in order to inject money into the economy to expand economic activity. Quantitative easing is an unconventional form of monetary policy, which is usually used when inflation is very low or negative, and when standard monetary policy instruments have become ineffective. Quantitative tightening (QT) does the opposite, where for monetary policy reasons, a central bank sells off some portion of its own held or previously purchased government bonds or other  financial assets, to a mix of commercial banks and other financial institutions, usually after periods of their own, earlier, Quantitative Easing purchases. Similar to conventional open-market operations used to implement monetary policy, a central bank implements quantitative easing by buying financial assets from commercial banks and other financial institutions, thus raising the prices of those financial assets and lowering their yield, while simultaneously increasing the money supply. However, in contrast to normal policy, quantitative easing involves the purchase of riskier assets (rather than short-term government bonds) of predetermined amounts at a large scale, over a pre-committed period  of time. Central banks usually resort to quantitative easing when their nominal interest rate target approaches or reaches zero. Very low interest rates induce a liquidity trap, a situation where people prefer to hold cash or very liquid assets, given the low returns on other financial assets. This makes it difficult for interest rates to go below zero; monetary authorities may then use quantitative easing to further stimulate the economy rather than trying to lower the interest rate further. Quantitative easing can help bring the economy out of recession and help ensure that inflation does not fall below the central  bank's inflation target. However QE programmes are also criticized for their side-effects and risks, which include the policy being more effective than intended in acting against deflation (leading to higher inflation in the longer term), or not being effective enough if banks remain reluctant to lend and potential borrowers are unwilling to borrow. Quantitative easing was undertaken by some major central banks worldwide following the global financial crisis of 2007–08, and again in response to the COVID-19 pandemic. In Canada, the central bank undertook quantitative easing during the Covid-19 pandemic, but not after the 2008 financial crisis. Process  and benefits. Standard central bank monetary policies are usually enacted by buying or selling government bonds on the open market to reach a desired target for the interbank interest rate. However, if a recession or depression continues even when a central bank has lowered interest rates to nearly zero, the central bank can no longer lower interest rates — a situation known as the liquidity trap. The central bank may then implement quantitative easing by buying financial assets without reference to interest rates. This policy is sometimes described as a last resort to stimulate the economy. A central bank enacts quantitative  easing by purchasing, regardless of interest rates, a predetermined "quantity" of bonds or other financial assets on financial markets from private financial institutions. This action increases the excess reserves that banks hold. The goal of this policy is to ease financial conditions, increase market liquidity, and encourage private bank lending. Quantitative easing affects the economy through several channels: History. The term "quantitative easing" was coined by German economist Richard Werner who was a visiting fellow at the Bank of Japan in 1995. Werner advocated quantitative easing as a way to overcome the limitations of the Bank's interest rate policy . The Bank of Japan however only introduced QE from March 19, 2001 until March 2006, after having introduced negative interest rates in 1999. Most western central banks adopted similar policies in the aftermath of the great financial crisis of 2008. In modern times, it is widely referred to as printing money. Precedents. The US Federal Reserve belatedly implemented policies similar to the recent quantitative easing during the Great Depression of the 1930s. Specifically, banks' excess reserves exceeded 6 percent in 1940, whereas they vanished during the entire postwar period until 2008. Despite this fact, many commentators called the scope of  the Federal Reserve quantitative easing program after the 2008 crisis "unprecedented". Japan (2001-2006). A policy termed "quantitative easing" (量的金融緩和, "ryōteki kin'yū kanwa") was first used by the Bank of Japan (BoJ) to fight domestic deflation in the early 2000s. The BOJ had maintained short-term interest rates at close to zero since 1999. The Bank of Japan had for many years, and as late as February 2001, stated that "quantitative easing ... is not effective" and rejected its use for monetary policy. The Bank of Japan adopted quantitative easing on 19 March 2001. Under quantitative easing, the BOJ flooded commercial  banks with excess liquidity to promote private lending, leaving them with large stocks of excess reserves and therefore little risk of a liquidity shortage. The BOJ accomplished this by buying more government bonds than would be required to set the interest rate to zero. It later also bought asset-backed securities and equities and extended the terms of its commercial paper-purchasing operation. The BOJ increased commercial bank current account balances from ¥5 trillion to ¥35 trillion (approximately US$300 billion) over a four-year period starting in March 2001. The BOJ also tripled the quantity of long -term Japan government bonds it could purchase on a monthly basis. However, the seven-fold increase notwithstanding, current account balances (essentially central bank reserves) being just one (usually relatively small) component of the liability side of a central bank's balance sheet (the main one being banknotes), the resulting peak increase in the BOJ's balance sheet was modest, compared to later actions by other central banks. The Bank of Japan phased out the QE policy in March 2006. After 2007. After the global financial crisis of 2007-08, policies similar to those undertaken by Japan were used by the  United States, the United Kingdom, and the Eurozone. Quantitative easing was used by these countries because their risk-free short-term nominal interest rates (termed the federal funds rate in the US, or the official bank rate in the UK) were either at or close to zero. According to Thomas Oatley, "QE has been the central pillar of post-crisis economic policy." During the peak of the financial crisis in 2008, the US Federal Reserve expanded its balance sheet dramatically by adding new assets and new liabilities without "sterilizing" these by corresponding subtractions. In the same period, the United Kingdom  also used quantitative easing as an additional arm of its monetary policy to alleviate its financial crisis. United States (QE1, QE2, and QE3). The U.S. Federal Reserve System held between $700 billion and $800 billion of Treasury notes on its balance sheet before the recession. November 2008: QE1. In late November 2008, the Federal Reserve started buying $600 billion in mortgage-backed securities. By March 2009, it held $1.75 trillion of bank debt, mortgage-backed securities, and Treasury notes; this amount reached a peak of $2.1 trillion in June 2010. Further purchases were halted as  the economy started to improve, but resumed in August 2010 when the Fed decided the economy was not growing robustly. After the halt in June, holdings started falling naturally as debt matured and were projected to fall to $1.7 trillion by 2012. The Fed's revised goal became to keep holdings at $2.054 trillion. To maintain that level, the Fed bought $30 billion in two- to ten-year Treasury notes every month. November 2010: QE2. In November 2010, the Fed announced a second round of quantitative easing, buying $600 billion of Treasury securities by the end  of the second quarter of 2011. The expression "QE2" became a ubiquitous nickname in 2010, used to refer to this second round of quantitative easing by US central banks. Retrospectively, the round of quantitative easing preceding QE2 was called "QE1". September 2012: QE3.A third round of quantitative easing, "QE3", was announced on 13 September 2012. In an 11–1 vote, the Federal Reserve decided to launch a new $40 billion per month, open-ended bond purchasing program of agency mortgage-backed securities. Additionally, the Federal Open Market Committee (FOMC) announced that it would likely maintain the federal funds rate near  zero "at least through 2015". According to NASDAQ.com, this is effectively a stimulus program that allows the Federal Reserve to relieve $40 billion per month of commercial housing market debt risk. Because of its open-ended nature, QE3 has earned the popular nickname of "QE-Infinity". On 12 December 2012, the FOMC announced an increase in the amount of open-ended purchases from $40 billion to $85 billion per month. On 19 June 2013, Ben Bernanke announced a "tapering" of some of the Fed's QE policies contingent upon continued positive economic data. Specifically, he said that  the Fed could scale back its bond purchases from $85 billion to $65 billion a month during the upcoming September 2013 policy meeting. He also suggested that the bond-buying program could wrap up by mid-2014. While Bernanke did not announce an interest rate hike, he suggested that if inflation followed a 2% target rate and unemployment decreased to 6.5%, the Fed would likely start raising rates. The stock markets dropped by approximately 4.3% over the three trading days following Bernanke's announcement, with the Dow Jones dropping 659 points between 19 and 24 June, closing at 14,660  at the end of the day on 24 June. On 18 September 2013, the Fed decided to hold off on scaling back its bond-buying program, and announced in December 2013 that it would begin to taper its purchases in January 2014. Purchases were halted on 29 October 2014 after accumulating $4.5 trillion in assets. US QE4. In March 2020, the Federal Reserve began conducting its fourth quantitative easing operation since the 2008 financial crisis; on 15 March 2020, it announced approximately $700 billion in new quantitative easing via asset purchases to support US liquidity in response to  the COVID-19 pandemic. As of mid-summer 2020 this resulted in an additional $2 trillion in assets on the books of the Federal Reserve. United Kingdom. During its QE programme, the Bank of England bought gilts from financial institutions, along with a smaller amount of relatively high-quality debt issued by private companies. The banks, insurance companies, and pension funds could then use the money they received for lending or even to buy back more bonds from the bank. Further, the central bank could lend the new money to private banks or buy assets from banks in exchange for  currency. These measures have the effect of depressing interest yields on government bonds and similar investments, making it cheaper for business to raise capital. Another side effect is that investors will switch to other investments, such as shares, boosting their price and thus encouraging consumption. QE can reduce interbank overnight interest rates and thereby encourage banks to loan money to higher interest-paying and financially weaker bodies. Beginning in March 2009, the Bank of England had purchased around £165 billion in assets as of September 2009 and around £175 billion in assets by the end of October 2009 . At its meeting in November 2009, the Monetary Policy Committee (MPC) voted to increase total asset purchases to £200 billion. Most of the assets purchased have been UK government securities (gilts); the Bank has also purchased smaller quantities of high-quality private-sector assets. In December 2010, MPC member Adam Posen called for a £50 billion expansion of the Bank's quantitative easing programme, while his colleague Andrew Sentance has called for an increase in interest rates due to inflation being above the target rate of 2%. In October 2011, the Bank of England announced that it would  undertake another round of QE, creating an additional £75 billion. In February 2012 it announced an additional £50 billion. In July 2012 it announced another £50 billion, bringing the total amount to £375 billion. The Bank has said that it will not buy more than 70% of any issue of government debt. This means that at least 30% of any issue of government debt will have to be purchased and held by institutions other than the Bank of England. In 2012 the Bank estimated that quantitative easing had benefited households differentially according to the assets they  hold; richer households have more assets. In August 2016, the Bank of England said it would buy an additional £60bn of UK government bonds and £10bn of corporate bonds, to address uncertainty over Brexit and worries about productivity and economic growth. In an emergency meeting due to the COVID-19 pandemic in March 2020, the Bank announced £200bn purchases of government bonds, a further £100bn was announced in June 2020 and another £150bn in November 2020, bringing the total to £895bn. Eurozone. The European Central Bank engaged in large-scale purchase of covered bonds in  May 2009, and purchased around 250 billion euros of sovereign bonds from targeted member states in 2010 and 2011 (the SMP Programme). However until 2015 the ECB refused to openly admit they were doing quantitative easing. In a dramatic change of policy, following the new Jackson Hole Consensus, on 22 January 2015 Mario Draghi, President of the European Central Bank, announced an "expanded asset purchase programme", where €60 billion per month of euro-area bonds from central governments, agencies and European institutions would be bought. Beginning in March 2015, the stimulus was planned to last until September 2016 at  the earliest with a total QE of at least €1.1 trillion. Mario Draghi announced the programme would continue: "until we see a continued adjustment in the path of inflation", referring to the ECB's need to combat the growing threat of deflation across the eurozone in early 2015. On 10 March 2016, the ECB increased its monthly bond purchases to €80 billion from €60 billion and started to include corporate bonds under the asset purchasing programme and announced new ultra-cheap four-year loans to banks. After a short pause of about a year, the ECB resumed  buying up eurozone government bonds at a rate of €20 billion as from November 2019 in an effort to encourage governments to borrow more and spend in domestic investment projects. On 18 March 2020, to help the economy absorb the shock of the COVID-19 crisis, the ECB announced a €750 billion Pandemic Emergency Purchase Programme (PEPP). The aim of the stimulus package (PEPP) was to lower borrowing costs and increase lending in the euro area. Switzerland. At the beginning of 2013, the Swiss National Bank had the largest balance sheet relative to the size of the economy it  was responsible for, at close to 100% of Switzerland's national output. A total of 12% of its reserves were in foreign equities. By contrast, the US Federal Reserve's holdings equalled about 20% of US GDP, while the European Central Bank's assets were worth 30% of GDP. The SNB's balance sheet has increased massively because of QE, to the point that in December 2020, when U.S. treasury accused Switzerland to be a "currency manipulator". The US administration recommended Switzerland to increase the retirement age for Swiss workers to reduce saving assets by the Swiss Social Security administration , in order to boost domestic demand and reduce the necessity to maintain QE to stabilize the parity between the dollar and the Swiss franc. Sweden. Sveriges Riksbank launched quantitative easing in February 2015, announcing government bond purchases of nearly US$1.2 billion. The annualised inflation rate in January 2015 was minus 0.3 percent, and the bank implied that Sweden's economy could slide into deflation. Japan after 2007 and Abenomics. In early October 2010, the Bank of Japan announced that it would examine the purchase of ¥5 trillion (US$60 billion) in assets. This was an attempt to push  down the value of the yen against the US dollar to stimulate the domestic economy by making Japanese exports cheaper; however, it was ineffective. On 4 August 2011 the BOJ announced a unilateral move to increase the commercial bank current account balance from ¥40 trillion (US$504 billion) to a total of ¥50 trillion (US$630 billion). In October 2011, the Bank expanded its asset purchase program by ¥5 trillion ($66bn) to a total of ¥55 trillion. On 4 April 2013, the Bank of Japan announced that it would expand its asset purchase program by  60 to 70 trillion Yen a year. The Bank hoped to bring Japan from deflation to inflation, aiming for 2% inflation. The amount of purchases was so large that it was expected to double the money supply. This policy has been named Abenomics, as a portmanteau of economic policies and Shinzō Abe, the former Prime Minister of Japan. On 31 October 2014, the BOJ announced the expansion of its bond buying program, to now buy ¥80 trillion of bonds a year. Effectiveness of QE. The effectiveness of quantitative easing is the subject of an intense dispute among researchers as  it is difficult to separate the effect of quantitative easing from other contemporaneous economic and policy measures, such as negative rates. Former Federal Reserve Chairman Alan Greenspan calculated that as of July 2012, there was "very little impact on the economy". Bank deposits in the Fed increased by nearly $4 trillion during QE1-3, closely tracking Fed bond purchases. A different assessment has been offered by Federal Reserve Governor Jeremy Stein, who has said that measures of quantitative easing such as large-scale asset purchases "have played a significant role in supporting economic activity". While the literature on the  topic has grown over time, it has also been shown that central banks' own research on the effectiveness of quantitative easing tends to be optimistic in comparison to research by independent researchers, which could indicate a conflict of interest or cognitive bias in central bank research. Several studies published in the aftermath of the crisis found that quantitative easing in the US has effectively contributed to lower long term interest rates on a variety of securities as well as lower credit risk. This boosted GDP growth and modestly increased inflation. A predictable but unintended consequence of the lower interest rates  was to drive investment capital into equities, thereby inflating the value of equities relative to the value of goods and services, and increasing the wealth gap between the wealthy and working class. In the Eurozone, studies have shown that QE successfully averted deflationary spirals in 2013-2014, and prevented the widening of bond yield spreads between member states. QE also helped reduce bank lending cost. However, the real effect of QE on GDP and inflation remained modest and very heterogeneous depending on methodologies used in research studies, which find on GDP comprised between 0.2% and 1.5% and between 0.1 and  1.4% on inflation. Model-based studies tend to find a higher impact than empirical ones. Risks and side-effects. Quantitative easing may cause higher inflation than desired if the amount of easing required is overestimated and too much money is created by the purchase of liquid assets. On the other hand, QE can fail to spur demand if banks remain reluctant to lend money to businesses and households. Even then, QE can still ease the process of deleveraging as it lowers yields. However, there is a time lag between monetary growth and inflation; inflationary pressures associated with money growth from  QE could build before the central bank acts to counter them. Inflationary risks are mitigated if the system's economy outgrows the pace of the increase of the money supply from the easing. If production in an economy increases because of the increased money supply, the value of a unit of currency may also increase, even though there is more currency available. For example, if a nation's economy were to spur a significant increase in output at a rate at least as high as the amount of debt monetized the inflationary pressures would be equalized. This can only happen  if member banks actually lend the excess money out instead of hoarding the extra cash. During times of high economic output, the central bank always has the option of restoring reserves to higher levels through raising interest rates or other means, effectively reversing the easing steps taken. Economists such as John Taylor believe that quantitative easing creates unpredictability. Since the increase in bank reserves may not immediately increase the money supply if held as excess reserves, the increased reserves create the danger that inflation may eventually result when the reserves are loaned out. QE benefits debtors, since the interest rate  has fallen, meaning there is less money to be repaid. However, it directly harms creditors as they earn less money from lower interest rates. Devaluation of a currency also directly harms importers and consumers, as the cost of imported goods is inflated by the devaluation of the currency. Impact on savings and pensions. In the European Union, World Pensions Council (WPC) financial economists have also argued that artificially low government bond interest rates induced by QE will have an adverse impact on the underfunding condition of pension funds, since "without returns that outstrip inflation, pension investors face the real value  of their savings declining rather than ratcheting up over the next few years". In addition to this, low or negative interest rates create disincentives for saving. In a way this is an intended effect, since QE is intended to spur consumer spending. Effects on climate change. In Europe, central banks operating corporate quantitative easing (i.e., QE programmes that include corporate bonds) such as the European Central Bank or the Swiss National Bank, have been increasingly criticized by NGOs for not taking into account the climate impact of the companies issuing the bonds. In effect, Corporate QE programmes are perceived as  indirect subsidy to polluting companies. The European Parliament has also joined the criticism by adopting several resolutions on the matter, and has repeatedly called on the ECB to reflect climate change considerations in its policies. Central banks have usually responded by arguing they had to follow the principle of "market neutrality" and should therefore refrain from making discretionary choices when selecting bonds on the market. The notion that central banks can be market neutral is contested, as central banks always make choices that are not neutral for financial markets when implementing monetary policy. Furthermore research has demonstrated that, in the  case of the ECB's corporate bond purchase programme, the principle of market neutrality is not a practical reality, as the ECB's purchases are concentrated on economic sectors that are not representative of the wider economy, and tend to be skewed towards carbon-intensive firms. Following this criticism, in 2020, several top level ECB policymaker such as Christine Lagarde, Isabel Schnabel, Frank Elderson and others have pointed out the contradiction in the market neutrality logic. In particular, Schnabel argued that "In the presence of market failures, market neutrality may not be the appropriate benchmark for a central bank when  the market by itself is not achieving efficient outcomes" Since 2020, several central banks (including the ECB, Bank of England and the Swedish central banks) have announced their intention to incorporate climate criteria in their QE programmes. The Network for Greening the Financial System has identified different possible measures to align central banks' collateral frameworks and QE with climate objectives. Increased income and wealth inequality. Critics frequently point to the redistributive effects of quantitative easing. For instance, British Prime Minister Theresa May openly criticized QE in July 2016 for its regressive effects: "Monetary policy – in the form of super-low  interest rates and quantitative easing – has helped those on the property ladder at the expense of those who can't afford to own their own home." Dhaval Joshi of BCA Research wrote that "QE cash ends up overwhelmingly in profits, thereby exacerbating already extreme income inequality and the consequent social tensions that arise from it". Anthony Randazzo of the Reason Foundation wrote that QE "is fundamentally a regressive redistribution program that has been boosting wealth for those already engaged in the financial sector or those who already own homes, but passing little along to the rest of the economy. It  is a primary driver of income inequality". Those criticisms are partly based on some evidence provided by central banks themselves. In 2012, a Bank of England report showed that its quantitative easing policies had benefited mainly the wealthy, and that 40% of those gains went to the richest 5% of British households. In May 2013, Federal Reserve Bank of Dallas President Richard Fisher said that cheap money has made rich people richer, but has not done quite as much for working Americans. Answering similar criticisms expressed by MEP Molly Scott Cato, the President of the ECB Mario Draghi once declared : Some of these policies may, on the one hand, increase inequality but, on the other hand, if we ask ourselves what the major source of inequality is, the answer would be unemployment. So, to the extent that these policies help – and they are helping on that front – then certainly an accommodative monetary policy is better in the present situation than a restrictive monetary policy.In July 2018, the ECB published a study showing that its QE programme increased the net wealth of the poorest fifth of the population by 2.5 percent, compared with just 1.0 percent for the richest fifth . The study's credibility was however contested. International spillovers for BRICs and emerging economies. Quantitative easing (QE) policies can have a profound effect on Forex rates, since it changes the supply of one currency compared to another. For instance, if both the US and Europe are using quantitative easing to the same degree then the currency pair of US/EUR may not fluctuate. However, if the US treasury uses QE to a higher degree, as evidenced in the increased purchase of securities during an economic crisis, but India does not, then the value of the USD will decrease relative to  the Indian rupee. As a result, quantitative easing has the same effect as purchasing foreign currencies, effectively manipulating the value of one currency compared to another. BRIC countries have criticized the QE carried out by the central banks of developed nations. They share the argument that such actions amount to protectionism and competitive devaluation. As net exporters whose currencies are partially pegged to the dollar, they protest that QE causes inflation to rise in their countries and penalizes their industries. In a joint statement leaders of Russia, Brazil, India, China and South Africa, collectively BRICS, have condemned the policies of  western economies saying "It is critical for advanced economies to adopt responsible macro-economic and financial policies, avoid creating excessive liquidity and undertake structural reforms to lift growth" as written in the Telegraph. According to Bloomberg reporter David Lynch, the new money from quantitative easing could be used by the banks to invest in emerging markets, commodity-based economies, commodities themselves, and non-local opportunities rather than to lend to local businesses that are having difficulty getting loans. Moral hazard. Another criticism prevalent in Europe, is that QE creates moral hazard for governments. Central banks’ purchases of government securities artificially  depress the cost of borrowing. Normally, governments issuing additional debt see their borrowing costs rise, which discourages them from overdoing it. In particular, market discipline in the form of higher interest rates will cause a government like Italy's, tempted to increase deficit spending, to think twice. Not so, however, when the central bank acts as bond buyer of last resort and is prepared to purchase government securities without limit. In such circumstances, market discipline will be incapacitated. Reputational risks. Richard W. Fisher, president of the Federal Reserve Bank of Dallas, warned in 2010 that QE carries "the risk of  being perceived as embarking on the slippery slope of debt monetization. We know that once a central bank is perceived as targeting government debt yields at a time of persistent budget deficits, concern about debt monetization quickly arises." Later in the same speech, he stated that the Fed is monetizing the government debt: "The math of this new exercise is readily transparent: The Federal Reserve will buy $110 billion a month in Treasuries, an amount that, annualized, represents the projected deficit of the federal government for next year. For the next eight months, the nation's central bank will  be monetizing the federal debt." Ben Bernanke remarked in 2002 that the US government had a technology called the printing press (or, today, its electronic equivalent), so that if rates reached zero and deflation threatened, the government could always act to ensure deflation was prevented. He said, however, that the government would not print money and distribute it "willy nilly" but would rather focus its efforts in certain areas (e.g., buying federal agency debt securities and mortgage-backed securities). According to economist Robert McTeer, former president of the Federal Reserve Bank of Dallas, there is nothing wrong with printing money  during a recession, and quantitative easing is different from traditional monetary policy "only in its magnitude and pre-announcement of amount and timing". Alternative policies. QE for the people. In response to concerns that QE is failing to create sufficient demand, particularly in the Eurozone, some have called for "QE for the people" or "helicopter money". Instead of buying government bonds or other securities by creating bank reserves, as the Federal Reserve and Bank of England have done, some suggest that central banks could make payments directly to households (in a similar fashion as Milton Friedman's helicopter money). Economists  Mark Blyth and Eric Lonergan argue in "Foreign Affairs" that this is the most effective solution for the Eurozone, particularly given the restrictions on fiscal policy. They argue that based on the evidence from tax rebates in the United States, less than 5% of GDP transferred by the ECB to the household sector in the Eurozone would suffice to generate a recovery, a fraction of what it intends to be done under standard QE. Oxford economist John Muellbauer has suggested that this could be legally implemented using the electoral register. On 27 March 2015, 19 economists including Steve Keen, Ann  Pettifor, Robert Skidelsky, and Guy Standing have signed a letter to the "Financial Times" calling on the European Central Bank to adopt a more direct approach to its quantitative easing plan announced earlier in February. In August 2019, prominent central bankers Stanley Fischer and Philip Hildebrand co-authored a paper published by BlackRock in which they propose a form of helicopter money. Carbon quantitative easing. Carbon quantitative easing (CQE) is an untested form of QE that is featured in a newly proposed international climate policy, called a global carbon reward. A major goal of CQE is to finance the global  carbon reward by managing the exchange rate of a new representative currency, called a carbon currency. The carbon currency will act as an international unit of account and a store of value, because it will represent the mass of carbon that is mitigated and rewarded under the global carbon reward policy. Fiscal policy. Keynesian economics became popular after the Great Depression. The idea is that in an economy with low inflation and high unemployment (especially technological unemployment), demand side economics will stimulate consumer spending, which increases business profits, which increases investment. Keynesians promote methods like public works, infrastructure redevelopment, and  increases in the social safety net to increase demand and inflation. Monetary financing. Quantitative easing has been nicknamed "money printing" by some members of the media, central bankers, and financial analysts. However, QE is a very different form of money creation than it is commonly understood when talking about "money printing" (otherwise called monetary financing or debt monetization). Indeed, with QE the newly created money is usually used to buy financial assets beyond just government bonds (corporate bonds etc.) and QE is usually implemented in the secondary market. In most developed nations (e.g., the United Kingdom, the United States, Japan , and the Eurozone), central banks are prohibited from buying government debt directly from the government and must instead buy it from the secondary market. This two-step process, where the government sells bonds to private entities that in turn sell them to the central bank, has been called "monetizing the debt" by many analysts. The distinguishing characteristic between QE and debt monetization is that with the former, the central bank creates money to stimulate the economy, not to finance government spending (although an indirect effect of QE is to lower rates on sovereign bonds). Also, the central bank has the  stated intention of reversing the QE when the economy has recovered (by selling the government bonds and other financial assets back into the market). The only effective way to determine whether a central bank has monetized debt is to compare its performance relative to its stated objectives. Many central banks have adopted an inflation target. It is likely that a central bank is monetizing the debt if it continues to buy government debt when inflation is above target and if the government has problems with debt financing. Some economists such as Adair Turner have argued that outright monetary financing would  be more effective than QE. Neo-Fisherism. Neo-Fisherism, based on theories made by Irving Fisher reasons that the solution to low inflation is not quantitative easing, but paradoxically to increase interest rates. This is due to the fact that if interest rates continue to decline, banks will lose customers and less money will be invested back into the economy. In a situation of low inflation and high debt, customers will feel more secure holding on to cash or converting cash into commodities, which fails to stimulate economic growth. If the money supply increases from quantitative easing, customers will subsequently  default in the face of higher prices, thus resetting the low inflation and worsening the low inflation issue.
