Often we need to teach an economic idea that we do not have a thourough, practical understanding of ourselves. The old “Keep it Simple” model is usually the best method with which to confront this dilemma.

The idea of good investment strategies crops up from many angles during any economics class. Households need to make wise choices in spending their disposable income. Business firms need to be efficient in deciding their growth options. The government and the banking sectors have tremendous control on the “values of economics progress.”

One device that has aided me is the use of the accounting Ballance Sheet. Balance sheets are used in essentially all economics textbooks to convey the notion of “How the Banking System Creates Money.” Here’s a good example:

When my son Brian was nine years old, we started playing the Parker Brother’s popular game Monopoly. Both of us began with $1500 in CASH (Diagram 1).

• Items on the LEFT SIDE are things “Owned” – Assets. Notice initially all $1500 is in the form of CASH.
• The RIGHT SIDE contains things “Owed” – Liabilities. (Initially $0)
• Also on the RIGHT SIDE: by finding ASSETS minus LIABILITIES we find NET WORTH.
• The purpose of the game is to increase this NET WORTH.

As the game progressed, Brian’s strategy was to build up his CASH. For the first thirty minutes of the game, Brian had a huge smile on his face. He started to hoard the goldenrod colored $500 bills. Enamored by his cash stash, he even turned in smaller units of monopoly currency for more golenrod bills.

Brian, looking over at my side of the board, even as a nine year old, mockingly tuanted me. He noticed that I “owned” only a measly few white $1 bills, some pink $5 bills, and only one dull yellow $10 bill. Obviously, he thaught that he was winning the game over his dad. Zeroing in only on the CASH, he didn’t observe that I also “owned” three green, red and yellow property deeds. Also, he couldn’t understand the reason whyI had “spent” cash on those nine green plastic houses that were sprinkled around the board.

Our Balance Sheets now looked like Diagram #2. Brians’s strategy was to build his cash holdings. By landing on “PASS GO, COLLECT $200″, “You’ve Won a Beauty Contest, Collect $10″, and similar monopoly situations, Brian’s CASH grew and so did his NET WORTH (modestly).

However, the next thirty minutes were mine (I started to smile and Brian began to cry). As he landed on my “ASSETS” his goldenrod currency flowed my way as RENTAL REVENUE. It didn’t take long for Dad to win by bankrupting his son.

The final Balance Sheets showed the ory details (Diagram #3). Brian’s CASH was now in my possession; however, notice how my strategy of investing in REVENUE-producing assets enabled my net worth to expand. Brian was bankrupt, his net worth was zero.

This simple story has served me very well in both high school and universtiy level Economics and Accounting courses. By the way, Brian is now a 27 year old Emergency Medicine medical resident at Christiana Medical Center, Christiana, Delaware, and has bankrupted me in Monopoly ever since this first learning experience!

In the last three months, the Japanese Yen has appreciated 15% against the US dollar. At the same, the dollar itself has appreciated 25% against the euro.

The appreciation of these two major currencies seems strange in a time when both country’s economies are experiencing major slowdowns. In most cases, currencies appreciate when one of two things happens:

• If foreigners demand more of a country’s exports, demand for its currency drives up its value, causing appreciation.
• If a country’s interest rates rise relative to other country’s, then demand for its currency rises as investors want to buy assets in that country to earn the higher interest rates.

Lately, however, the Yen and the Dollar have seen staggering rises in the absence of rising exports or rising interest rates in Japan or the US. So what IS causing the rapid and drastic appreciation of these two currencies? The Economist newspaper explains:

Many investors have been following a version of the “carry trade”, borrowing money in a low-yielding currency. All they had to do was earn a higher return from assets than the cost of their financing. Since the two big currencies with the lowest yields over the past year have been the dollar and the yen, those were the natural ones to borrow.

When asset prices fall, however, this strategy is disastrous. Investors dash to sell assets and repay their debts. Since those debts were incurred in dollars and yen, that means they have to buy back those two currencies—hence their sharp recent rises.

In the midst of today’s global financial meltdown, it seems that every day, phenomena new to mainstream economic theory are being witnessed. It would seem that from now on, when we learn about the determinants of exchange rates, we may have to take a look at the “carry trade” example.

In this case, it would seem, LOW interest rates combined with falling stock prices can lead to a currency’s appreciation. An investor looking to make a deal would borrow Yen from a Japanese bank charging low interest rates, convert it to, let’s say Brazilian real, to buy stocks in a Brazilian company. As long as the stocks gain value at a rate higher than the interest rate in Japan, the investor is making an easy profit. He can pay back the money he borrowed from Japan at the low interest rate, earn a high return on his investment in Brazil, and pocket the difference.

The problem arises when the value of the assets the investor has bought in Brazil begins to fall. With stock markets plummeting between 20-50% this year in most countries, asset values have fallen through the floor, meaning those investors who borrowed yen to buy foreign assets have rushed to sell the falling assets as quickly as possible to pay back their Japanese lenders before it’s too late. This causes a huge increase in demand for Yen on foreign exchange markets in a very short period, hence the yen’s appreciation.

Recently, the Yen and USD have managed to appreciate for a reason not conventionally understood. The rapid and drastic appreciation of these currencies is further exacerbating the weak aggregate demand in Japan and the US. A strong currency, while good for consumers for whom imports appear cheaper, can have debilitating effect on a country’s export sector. Not surprisingly, both the US Fed and the Japanese central bank have both cut interest rates in the last week in the hope of slowing their currency’s appreciation and protect export demand.

Newsweek international edition editor Fareed Zakaria explains in clear terms the root causes of the United State’s economic hardships. Simply put, Americans have lived beyond their means for far too long.

When a household, a firm, or a national government spend more than it earns (in income or tax revenues), it must borrow to do so. The only problem with this type of deficit financed spending is that at some point “the only way people will keep lending you money is that you have to pay higher and higher interest rates…” This, according to Zakaria, is why the US economy has begun to slow down. Higher interest rates make borrowing and spending less and less attractive, while making savings more attractive.

Savings rates have started to rise in America as our debts have come due. Higher savings means less spending, less spending means weak Aggregate Demand, which means slower growth and rising unemployment. There you have it, the root cause of our economic meltdown. Americans have spent beyond their means for far too long; the question is, have we learned our lesson? Will our current hardships teach us to spend more responsibly in the future?

So Wall Street has recently experienced its worst shocks since the great depression. Every day the Dow Jones is like a roller coaster, DOWN 800 points, then  UP 500 points, then DOWN 200 followed by another rally of 600! In just three weeks the Dow has gone from 11,500 to below 900 points. Surely, the wise thing to do is get OUT of the stock market, right? WRONG! At least, so says the richest man in the world, Warren Buffet, someone who should know a thing or two about smart investing.

Why?

A simple rule dictates my buying: Be fearful when others are greedy, and be greedy when others are fearful. And most certainly, fear is now widespread, gripping even seasoned investors. To be sure, investors are right to be wary of highly leveraged entities or businesses in weak competitive positions. But fears regarding the long-term prosperity of the nation’s many sound companies make no sense. These businesses will indeed suffer earnings hiccups, as they always have. But most major companies will be setting new profit records 5, 10 and 20 years from now.

Let me be clear on one point: I can’t predict the short-term movements of the stock market. I haven’t the faintest idea as to whether stocks will be higher or lower a month — or a year — from now. What is likely, however, is that the market will move higher, perhaps substantially so, well before either sentiment or the economy turns up. So if you wait for the robins, spring will be over.

A little history here: During the Depression, the Dow hit its low, 41, on July 8, 1932. Economic conditions, though, kept deteriorating until Franklin D. Roosevelt took office in March 1933. By that time, the market had already advanced 30 percent. Or think back to the early days of World War II, when things were going badly for the United States in Europe and the Pacific. The market hit bottom in April 1942, well before Allied fortunes turned. Again, in the early 1980s, the time to buy stocks was when inflation raged and the economy was in the tank. In short, bad news is an investor’s best friend. It lets you buy a slice of America’s future at a marked-down price.

Over the long term, the stock market news will be good. In the 20th century, the United States endured two world wars and other traumatic and expensive military conflicts; the Depression; a dozen or so recessions and financial panics; oil shocks; a flu epidemic; and the resignation of a disgraced president. Yet the Dow rose from 66 to 11,497.

You might think it would have been impossible for an investor to lose money during a century marked by such an extraordinary gain. But some investors did. The hapless ones bought stocks only when they felt comfort in doing so and then proceeded to sell when the headlines made them queasy.

Today people who hold cash equivalents feel comfortable. They shouldn’t. They have opted for a terrible long-term asset, one that pays virtually nothing and is certain to depreciate in value. Indeed, the policies that government will follow in its efforts to alleviate the current crisis will probably prove inflationary and therefore accelerate declines in the real value of cash accounts.

Equities will almost certainly outperform cash over the next decade, probably by a substantial degree. Those investors who cling now to cash are betting they can efficiently time their move away from it later. In waiting for the comfort of good news, they are ignoring Wayne Gretzky’s advice: “I skate to where the puck is going to be, not to where it has been.”

I don’t like to opine on the stock market, and again I emphasize that I have no idea what the market will do in the short term. Nevertheless, I’ll follow the lead of a restaurant that opened in an empty bank building and then advertised: “Put your mouth where your money was.” Today my money and my mouth both say equities.

Discussion Questions:

1. Why does holding cash seem like the smart thing to do during periods of volatile stock prices like the last month or so? Why does Mr. Buffet think that holding cash is NOT so smart?
2. Mr. Buffet’s advice is counter-intuitive to some. Buying more of something that is falling in value (American stocks) may appear unwise… but what is Buffet’s rationale for why buying now may in fact be the smartest thing for an investor to do?
3. Does the behavior of investors on the stock market reflect the behavior of consumers in a typical product market? In other words, do the laws of supply and demand apply to the stock market? Discuss…

European governments bail out more lenders – International Herald Tribune

As the US financial system holds its breath to see if the US government’s injection of $700 billion of liquidity actually results in new lending and restored business and consumer confidence, Europe is beginning to see its own government takeovers of European banks.

Regulators in Britain, Belgium and Iceland swooped in Monday to engineer emergency rescues of three banks with heavy exposure to soured mortgages, echoing moves underway in the United States.

In the latest sign of trouble to hit Europe from the global credit crisis, the Belgian, Dutch and Luxembourg governments announced a partial nationalization of the troubled Belgian-Dutch financial conglomerate Fortis, involving a combined injection of €11.2 billion from the three governments, which take a 49 percent stake…

Meanwhile, the British Treasury on Monday confirmed that it had seized the lender Bradford & Bingley – the third British bank to tumble this year – after no private buyers emerged.

Much as in the United States, several European banks have gotten into trouble as their assets tied to real estate have lost value due to the weak European and American real estate markets. As more and more borrowers are unable to pay their mortgages, banks’ assets decline in value and the banks’ willingness and ability to make new loans decreases. This limits the amount of credit available to households and firms, and with it their ability to make investments in consumer goods and capital. Tighter credit markets mean weaker aggregate demand (less consumption and investment), leading to slower or negative economic growth and rising unemployment.

In the past, when one bank got into trouble with bad assets like those tied to the real estate market, other private banks would come along and bail the troubled bank out, swapping cash for the assets, allowing the troubled bank to continue making loans. But when all banks find themselves in the midst of the same financial crisis, the likelihood of finding a private buyer for a struggling bank is low. This is where the government steps in:

The bailout of Fortis (Belgium’s largest commercial bank) orchestrated by the three neighboring countries (Belgium, Luxembourg and the Netherlands) and the ECB (European Central Bank)… was meant to restore confidence in the bank before the reopening of markets on Monday after a tumultuous week of imploding share values at Fortis. The shares gained 4.8 percent to €5.45 Monday.

In Britain, regulators were unable to find buyers to keep Bradford & Bingley afloat. The lender’s shares are down 90 percent from the peak, touching new depths Friday as an already skittish market punished the company, prompting the talks.

When the private sector is unable or unwilling to purchase the assets of a bank that has experienced a write down of its asset value, the government must intervene to make sure such banks have the liquidity (meaning the hard cash) they need to make loans to borrowers, whose spending is needed to keep the economy going.

In the US, the government has agreed to trade $700 billion in hard, loanable and spendable cash, in exchange for financial assets tied to bad mortgages worth something less than $700 billion. If the swap has the effect the government hopes it will, then lending institutions will feel more confidence and be willing to loan cash to each other and to borrowers (households and firms), spending in the economy will increase (consumption and investment) and aggregate demand will rise, meaning more total output, more employment and higher incomes. In addition, more lending will also lead to an increase in the capital stock, effectively pushing the American and European aggregate supply curves outwards, leading to a more stable rate of inflation (a major worry for both economies as oil prices hit record levels this year).

In spite of the recent round of bailouts in both the US and Europe, confidence among European firms and households is low:

Euro-zone economic confidence plunged to its lowest level in seven years in September, the EU said Monday.

A regular survey of European companies and consumers showed the index of confidence in the economy falling to 87.7, close to a 2001 trough, the European Commission said.

The EU executive warned that the survey carried out in the first two weeks of September may not fully reflect growing gloom in the last few weeks as worries over a U.S. and European recession widened on a financial market crisis.

Industry, services and construction were all more pessimistic than a month ago, it said, while consumer confidence was unchanged from a low level. Retailers were slightly more upbeat about their prospects.

It said industry managers’ employment expectations fell – meaning they believe they may have to cut jobs – although services companies were more hopeful.

Consumers thought that unemployment would increase in future months and expect prices to rise.

The 15 nations that share the euro are battling high inflation as oil prices remain high – although below recent record levels – and increasing fears that a financial crisis will freeze or sharply hike the cost of borrowing.

That would slow growth as companies found it harder to get credit and people faced high costs to buy homes. The U.S. government is trying to stave off tighter credit conditions by buying up hundreds of billions of dollars of bad debt from major lenders

As can be seen, falling confidence and tighter credit markets are evil twins. If the Euro zone economy is to avoid recession, the European Central Bank and the governments of the 15 Euro nations should follow closely events in the US over the next few weeks. The $700 billion injection of liquidity, if successful, will act as lubrication in the engine of the US economy.

Think of it this way: lately, the US economic engine has slowed down. Friction in the financial markets has slowed the flow of cash from households to banks to firms and back to households. In IB and AP Economics terms, the circular flow of money and income has slowed to a halt. To get the engine moving again, cash is needed. Banks with liquid cash are more willing to lend to one another and to households and firms. A healthy economy depends on a well lubricated economic engine, which in today’s world means a functioning financial market.

The government bailouts in the US and Europe are intended to do one thing: lubricate that engine and get the economy moving forward once more.

Discussion question:

1. Why does the government need to intervene in financial markets? Shouldn’t those who took risks by making bad loans pay for their mistakes and be allowed to go under?
2. What will it take to turn consumer and investor confidence around in Europe?
3. How might the crisis in the financial markets affect you and me in the real world?

How Does the Stock Market Effect The Economy? | Economics Blog

Well, a few things… Generally, the fluctuations of the stock market do not necessarily bode ill for the whole economy. Likewise, global fluctuations of stock markets does not mean there is a recession on the horizon. In fact, an old adage says that “stock markets have predicted ten out of the last three recessions.” In other words, a slump in global markets does not always precipitate a slump in the world’s economy. Here’s some impacts the market crashes of the last few days may have, however, explained nicely by Richard Pettinger, an economics teacher in the UK:

Economic Effects of Stock Market

1. Wealth Effect: The first impact is that people with shares will see a fall in their wealth. If the fall is significant it will affect their financial outlook. If they are losing money on shares they will be more hesitant to spend money; this can contribute to a fall in consumer spending. However, the effect should not be given too much importance. Often people who buy shares are prepared to lose money; their spending patterns are usually independent of share prices, especially for short term losses.

2. Effect on Pensions: Anybody with a private pension or investment trust will be affected by the stock market, at least indirectly. Pension funds invest a significant part of their funds on the stock market. Therefore, if there is a serious fall in share prices, it reduces the value of pension funds. This means that future pension payouts will be lower. If share prices fall too much, pension funds can struggle to meet their promises. The important thing is the long term movements in the share prices. If share prices fall for a long time then it will definitely affect pension funds and future payouts.

3. Confidence: Often share price movements are reflections of what is happening in the economy. E.g. recent falls are based on fears of a US recession and global slowdown. However, the stock market itself can affect consumer confidence. Bad headlines of falling share prices are another factor which discourage people from spending. On its own it may not have much effect, but combined with falling house prices, share prices can be a discouraging factor.

4. Investment: Falling share prices can hamper firms ability to raise finance on the stock market. Firms who are expanding and wish to borrow often do so by issuing more shares – it provides a low cost way of borrowing more money. However, with falling share prices it becomes much more difficult.

One of the many reasons that I find the study of economics so fascinating is that what so often appears to be a negative situation to the average citizen is actually a positive one. In other words: “down is often up” and “black is often white”. One of my favorite examples of this “180 degree moment”, and why I love to teach AP Macroeconomics, relates to the study of unemployment.

Jason,

An AP Macro Question: Comes from the recently published AP Practice Exam

An increase in which of the following is most likely to promote economic growth?

A. Consumption Spending
B. Investment Tax Credits
C The natural rate of unemployment
D The trade deficit
E Real Interest Rates.

The answer is B, and I understand the economic principles of why that would promote economic growth, but what I can’t answer for my students is why A, Consumption Spending wouldn’t work. I know that consumption spending makes up part of the demand in aggregate demand, but I can’t help but think that an increase in it, would promote economic growth.

Thanks, “Econ Teacher”

For what it’s worth, here is my reply:

Hello “Econ Teacher”,

That’s a good question. I would explain to my students that in the (In macroeconomics): The period of time over which wages and prices are relatively inflexible. A fall in aggregate demand will lead to unemployment and recession in the short-run. Due to the inability of the nation's producers to reduce wages paid to worker, they must lay workers off to reduce costs as demand falls.');" onmouseout="tooltip.hide();">short-run, an increase in AD alone will lead to some growth, but would be accompanied by inflation, since AS does not shift out when consumption increases. However, an investment tax credit will result in REAL long-run economic growth (by real I mean nominal GDP will increase while the price level remains stable), since it encourages investment. Investment is a determinant of AD, just like consumption, so AD will shift out, but it is also a determinant of AS, since firms are investing in capital. Increase the quantity or the quality of capital, and labor becomes more productive. Greater productivity shifts out AS, leading to growth AND stable prices.

Economic growth is defined, in terms of the AD/AS model, as an outward shift of both AD and AS. Increases in consumption will increase AD, but this will lead to inflation, and in the long run, workers will demand higher wages, increasing the costs of production and shifting AS leftward, returning the economy to the full employment level of output at an even higher price level, i.e. no economic growth occurs (see graph to the right). Investment, however, encouraged through a tax credit, will have positive demand and supply side effects, resulting in real economic growth and stable prices (see graph below)

Hope that helps!

Much hoopla is made over the US Federal Reserve’s power to affect markets through its injections of liquidity into the economy. These days, the Fed appears to have some new tricks up its sleeve, but still uses its traditionally dominant tool of Open Market Operations to affect the Federal Funds rate, and thus the interest rates that commercial banks charge borrowers financing consumption and investment.

The power of monetary policy lies in the fact that spending stimulus can be achieved without running the risk of crowding-out, wherein expansionary fiscal policy drives up interest rates, potentially off-setting any increases in aggregate demand by triggering declines in consumption and investment due to increased borrowing costs.The whole aim of expansionary monetary policy, on the other hand, is to drive interest down by increasing the reserves held by commercial banks.

The cartoon above illustrates the process that leads to lower interest rates and greater spending when the Fed undertakes expansionary open market operations. Government bonds (the blue bills above) are held as assets by both commercial banks and the public. These are illiquid, meaning they cannot be spent. In order to stimulate new spending, the Fed can take some of its reserves of money (the green bills), and buy bonds from the public and banks.

Banks receive cash from the Fed, which increases their excess reserves. Further, the public will deposit the checks they receive from the Fed into their banks, increasing checkable deposits, which add to both the banks’ required reserves and excess reserves. The result is banks now have new liquidity that they want desperately to lend out in order to earn interest (remember, banks rarely want to hold onto their excess reserves, because inflation will erode the value of any money that’s not earning interest!).

When banks’ reserves increase, due to their growing checkable deposits and the inflow of cash from the Fed’s purchase of bonds, the supply of “federal funds” shifts down, lowering the interest rates that banks charge one another for overnight loans. These are loans that banks often give and receive in order to meet their reserve requirements at the end of a business day.

For example: If Bank A has finds at the end of the day that it has received more deposits than withdrawals, and it now has $1m more in its reserves than it is required to have, it wants to lend that money out as soon as possible to earn interest on it. Bank B, it just so happens, received more withdrawals than it did deposits during the day, and is $1m short of its required reserves at day’s end. Bank B can borrow Bank A’s excess reserves in order to meet its reserve requirement. Bank A will not lend it for free, however, and the rate it charges is called the “federal funds” rate, since banks’ reserves are held predominantly by their district’s Federal Reserve Bank.

When the Fed buys bonds, all banks experience an increase in their reserves, meaning the supply of federal funds shifts out (or down in the graph above), lowering the “price” of federal funds, i.e. the federal funds rate. Lower interest rates on overnight loans will encourage banks to be more generous in their lending activity, allowing them to lower the prime interest rate (the rate they charge their most credit-worthy borrowers), which in turn should have a downward effect on all other interest rates.

Expansionary monetary policy involves the buying of government bonds on from the public and commercial banks by the Federal Reserve Bank. The result of this buying of bonds is an increase in the money supply, a decrease in real interest rates, and hopefully the stimulus of aggregate demand through new consumption and investment. Unlike expansionary fiscal policy (such as the stimulus package announced by Congress last month), crowding-out should not occur. Ideally, lowering the federal funds rate will lead to lower interest rates across the economy as a whole.

This, however, does not always transpire. In a future post, we’ll discuss why, and look at what the Fed is experimenting with today to stimulate investment and consumption, in response to the apparent failure of open market operations at providing the needed stimulus.

Job losses worst in five years – Mar. 7, 2008

The news late last week out of Washington was not what the White House was hoping for only a couple of weeks after the passing of a fiscal stimulus package meant to achieve exactly the opposite of what has happened. The US Labor Department released its latest numbers on employment on Friday:

There was a net loss of 63,000 jobs, which is the biggest decline since March 2003 and weaker than the revised 22,000 jobs lost in January. Economists had forecast a gain of 25,000 jobs…

“Based on today’s Employment Report, if we are not in a recession, it is a darned good imitation of one,” said Kevin Giddis, managing director of fixed income at Morgan Keegan.

So with a net loss of jobs, it may seem weird to hear that unemployment has actually fallen from 4.9% to 4.8%. How is this possible? In this case lower unemployment may indicate an even worse reality for the American economy:

The unemployment rate fell because of an increase of 450,000 people whom the government no longer counts as being part of the labor force for a variety of factors, such as that they are not currently looking for work. That drop in the size of the labor force allowed for the modest decline in unemployment, even as the household survey showed 255,000 fewer Americans with jobs than in January.

Discouraged workers point to a deep pessimism underlying households and workers in America, indicating that if we’re not already in a recession, it is only a matter of time. With the apparent failure of fiscal policy at achieving any immediate turnaround in consumer confidence, all eye’s are now on the Fed, America’s central bank, to see how Ben Bernanke will respond to the latest round of bad news.

“Even the silver lining of a falling unemployment rate has a little rust,” said Rich Yamarone, director of economic research at Argus Research. He predicted that the central bank will cut rates by a half percentage point at both its March meeting and again on April 30.

But Yamarone and some other experts questioned whether additional Fed cuts would do much to improve the employment outlook.

“We’re not in a crisis because the cost of borrowing is too high, it’s because people are afraid of lending,” said Dan Alpert, managing director of Westwood Capital, referring to the ongoing credit crunch. “At the end of the day, the Fed cuts don’t really solve the problems. They’ve already cut allot; if jobs continue to decline in face of further interest rate cuts, it’s prima facie evidence cuts aren’t effective.”

But few experts were ready to suggest the Fed would stop cutting rates at this point, given the problems in the economy and financial markets.

“The Fed has to do what it can to provide remedy and not scare the market as well,” said Mike Materasso, a senior portfolio manager at Franklin Templeton.

Central bankers face difficult decisions in times like these. While unemployment and falling growth rates pose significant problems to the American economy, the third macroeconomic evil is certainly in the minds of policymakers when deciding how to deal with the first two: inflation.

In order to lower interest rates, the Fed first has to implement expansionary monetary policy. In other words, the central bank must increase America’s money supply. How does it do this, exactly? Most commonly, the Fed uses open market operations, which is a fancy way of saying the Fed buys and sells government securities (treasury notes, bonds, etc…) on the bond market. When the Fed wishes to lower interest rates, it must inject new money into the economy, which it does by buying government bonds from the holders of those securities; namely, the public.

American banks, households, and firms, as well as foreigners all hold government debt. When the Fed wants to expand the money supply, it simply starts buying these debt securities back from the public. The increase in demand for securities drives up their prices, encouraging holders of the debt to sell their securities to the Fed, for which they receive money in exchange. In effect, the public exchanges illiquid (unspendable) debt certificates for liquid money. Now consumers have more money in their pockets to spend, firms have more to invest, and banks have more to loan out to borrowers who want to spend and invest. How do banks get rid of their new liquidity? Yep, they lower their interest rates.

In a nutshell, that’s how monetary policy works. To combat a recession and rising unemployment, the Fed simply buys bonds on the open market, injecting liquidity into the economy, which should result in more borrowing and more spending, shifting aggregate demand out, leading to growth and rising employment.

But what about that third evil, inflation? Won’t more spending lead to demand pull inflation? Usually this is not a major concern in times of a slowdown, since rising unemployment indicates the economy is producing below its full employment level of output. Expanding aggregate demand should result in increased output and stable prices. Today, however, Americans are facing other inflationary pressures, including a historically weak dollar (meaning imported goods and raw materials are more expensive than ever), and skyrocketing food and energy prices due to rising global demand for such commodities.

This all makes the job of monetary policy exceptionally challenging for Mr. Bernanke and his colleagues at the Fed. Expand the money supply too much (i.e. lower interest rates too much) and you risk accellerating inflation. Keep rates too high, and we can expect even worse employment and output numbers in the next few months.
