Once again, my IB Economics students are working on yet another Internal Assessment Commentary, this time on syllabus section 3, Macroeconomics. Since they found my sample Microeconomics commentary so helpful, I thought I’d punch out a quick sample of a macro commentary for them and for anyone else who is working on their IB Economcis Internal Assessment.

The commentary below (not including the selection from the article) is 749 words in length. This does NOT include words in the graphs, so let’s not have that debate in the comment section. The new IB economics internal assessment model (first examinations 2013) will not count words on graphs, so this sample commentary is perfectly suited for the new assessment model. If you’re a 2012 student, you would be wise to count words in graphs as part of your word count.

If you like what you see, or have any quesitons, please leave your comments below the post.

An Impeccable Disaster – NYTimes.com

Paul Krugman clearly explains the problems faced by two or Europe’s largest economies today:

So why is Spain — along with Italy, which has higher debt but smaller deficits — in so much trouble? The answer is that these countries are facing something very much like a bank run, except that the run is on their governments rather than, or more accurately as well as, their financial institutions.

Here’s how such a run works: Investors, for whatever reason, fear that a country will default on its debt. This makes them unwilling to buy the country’s bonds, or at least not unless offered a very high interest rate. And the fact that the country must roll its debt over at high interest rates worsens its fiscal prospects, making default more likely, so that the crisis of confidence becomes a self-fulfilling prophecy. And as it does, it becomes a banking crisis as well, since a country’s banks are normally heavily invested in government debt.

Now, a country with its own currency, like Britain, can short-circuit this process: if necessary, the Bank of England can step in to buy government debt with newly created money. This might lead to inflation (although even that is doubtful when the economy is depressed), but inflation poses a much smaller threat to investors than outright default. Spain and Italy, however, have adopted the euro and no longer have their own currencies. As a result, the threat of a self-fulfilling crisis is very real — and interest rates on Spanish and Italian debt are more than twice the rate on British debt.

Commentary:

The European Central Bank (ECB) is engaging in a new form of monetary policy in which it buys government bonds directly from the Spanish and Italian governments. Essentially, the goal is to bring down the interest rates on Italian and Spanish government bonds, which should reassure private investors that Italy and Spain will be able to pay them back and thus reduce the upward pressure on interest rates in the Eurozone, a situation which threatens to reverse the already sluggish recovery from the recessions of 2008 and 2009.

Monetary policy refers to a central bank’s manipulation of the money supply and interest rates, aimed at either increasing interest rates (contractionary monetary policy) or reducing interest rates (expansionary monetary policy). The ECB is currently buying government bonds from European governments, effectively increasing the supply of money in Europe with the hope that more government and private sector spending will move the Eurozone economy closer to its full employment level of output, at which workers, land and capital resources are fully employed towards the production of goods and services.

If successful, the ECB’s “quantitative easing”, as the new type of monetary policy is known, should bring down interest rates on government bonds and thereby reallocate loanable funds towards Italy and Spain’s public and private sectors.  The increase in supply of loanable funds should bring down the private interest rates available to borrows (businesses and households), making private investment more attractive.

The ECB’s bond purchases make it cheaper for Italy and Spain to borrow, lowering the interest rates on their bonds, restoring confidence among international investors, who may be more willing to save their money in Italy in Spain. The inflow of loanable funds into these economies (seen as an increase in the supply of loanable funds from S1 to S2) should bring down private borrowing costs (the real interest rate), encouraging more firms to invest in capital and more households to finance the consumption of durable goods, increasing aggregate demand and moving the Eurozone economy back towards its full employment level of output, from AD1 to AD2 in the graph on the right.

In certain circumstances, monetary easing like this could be inflationary, but in reality inflation is unlikely to occur given the large output gap in Europe at present (represented above as the distance between Y1 and the dotted line, signifying the full employment level of output). Any increase in aggregate demand will lead to economic growth (an increase in output), but little or no inflation due to the excess capacity of unemployed labor, land and capital resources in the European economy today.

With private sector borrowing costs increasing due to growing uncertainty over their deficits and debts, the Italian and Spanish governments will find expansionary fiscal policies (tax cuts and increased government expenditures) are unrealistic options for achieving the goal of full employment. The ECB, however, as Krugman argues, should continue to play an increasing role in the expansion of credit to cash strapped European governments, with the aim of keeping interest rates low to prevent the crowding-out of private spending that often occurs in the face of large budget deficits. Inflation, always a concern for central bankers, should be a low priority in Europe’s current recessionary environment. Only when consumer and investor confidence is restored, a condition that requires low borrowing costs, will private sector spending resume and the Euro economies can begin creating jobs and increasing their output again.

In the short-term, Italy and Spain should take advantage of the ECB’s bond-buying initiative, and make meaningful, productivity-enhancing investments in infrastructure, education and job training. If their economies are to grow in the future, Eurozone countries must become more competitive with the rapidly expanding economies of Asia, Eastern Europe, and elsewhere in the developing world.

In the medium-term, the Eurozone countries must demonstrate a commitment to fiscal restraint and more balanced budgets. Eliminating loopholes that allow businesses and wealthy individuals to avoid paying taxes, for example, is of utmost importance. Also, increasing the retirement age, downsizing some of the more generous social welfare programs and increasing marginal tax rates on the highest income earners would all send the message to investors that these countries are commited to fiscal discipline. Then, in time, their dependence on ECB lending will decline and private lenders will once again be willing to buy Eurozone government bonds at lower interest rates, allowing for continued growth in the private sector.

Economic Growth Yet to Hit Job Market – washingtonpost.com

In AP and IB Economics, we understand the importance of macroeconomics to policymakers, whose primary macroeconomic goal is growth. Economic Growth, defined as an increase in a nation’s total output of goods and service (and therefore the national income), is desidred not only for the sake of growth itself (producing more stuff requires more resources, and may not necessarily make the average citizen better off), rather growth is needed in order to achieve full-employment of a nation’s labor force.

Growth is good. This tenet of economics is rooted in two basic observations: 1. Growth leads to an improvement in the average standard living of a nation’s people, and 2. Growth is needed to employ the growing workforce of a nation experiencing population growth and immigration.

America’s work force is a diverse group of people of all skill levels. 150 million strong, the nation’s workforce requires a healthy national economy with strong investment and consumption to maintain enough jobs to keep unemployment low.   In the last two years, however, the prospect of employment in America has diminished as the number of people out of work has grown to nearly 15 million.

Involuntary unemployment is perhaps the most serious cost of an economic slowdown. A willing and able worker (or 15 million of them!), skilled in mind and body, unable to find prouductive work, represents a monumental failure of a nation’s economy. Policies aimed at promoting growth are in fact aimed at creating employment.

The costs of unemployment affect not only the unlucky  individuals who have have lost their job. Social costs include increased crime and poverty, psychological costs include stress, anxiety, loss of self-image and depression. The economic costs are myriad. Unemployed workers become dependent on the rest of society for support, in one way or another. Benefits for the unemployed payed by the government require greater budget deficits or increased tax burden on the employed. The large pool of jobless citizens seeking work puts downward pressure on the wages of those still working, as employers find it difficult to keep paying high wages while demand for their products has fallen and millions of job seekers are willing to work for less.

The families and friends to whom unemployed workers turn for help find their already stretched incomes spread even thinner. Without steady incomes, the unemployed consume less, putting further strain on an already depressed economy. Deflation can result from unemployment, which can lead to futher layoffs by pessimistic firms, excacerbating the situation and plunging the economy into what’s known as a deflationary spiral.

For all the reasons above, policymakers strive to promote growth. When monetary policy fails to incite spending, the government must pick up the slack, hence the stimulus package so discussed in America today. China’s stimulus of over $500 billion (twice that of the US, as a percentage of its GDP) has had a positive effect on both GDP and the job market.

Employment levels in China began to recover over the past three months in the latest evidence of the rapid rebound in the economy from the international financial crisis as a result of heavy public investment.

Yin Weimin, China’s labour minister, said there had been a modest increase in the number of jobs in the economy during June, July and August, reversing the sharp slump in employment which began last October.

America’s stimlus has also begun to restore growth, but the rise in employment has so far not occured:

Despite an emerging economic expansion, businesses were sufficiently skittish about the future that the job market continued its long, steep decline in August, according to a new government report Friday. The unemployment rate rose to 9.7 percent, from 9.4 percent, as employers shed jobs for the 20th straight month, the Labor Department said.

“Our clients tell us they will not hire in anticipation

of a recovery, but will wait until they see it,” said Jonas Prising, an executive vice president at Manpower, the giant employment services firm. “In a normal recession, people would now start to feel more comfortable and start hiring, but nobody is doing that today. They’ll do it when they see real orders and real business.”

The “silver lining” of the latest unemployment figures is hardly encouraging. The rise in unemployment is not as sharp as over most of the last year. In other words, workers are definitely worse off, but not as badly as they could have been if things were as dismal as they were earlier this year.

While the unemployment rate, as seen on the graph to the right, has risen almost every month since August of 2008, the rate at which the rate has increased has begun to slow. In other words, the economy is probably close to “bottoming out”.

The tally of lost jobs now stands at 6.9 million since the beginning of the recession in December 2007. But the rate of job losses has been declining, if haltingly, since winter. The 216,000 jobs eliminated in August is down from 276,000 cut in July and a peak of 741,000 lost in January.

Here’s what I find most interesting from in the current data. The unemployment rate’s recent rise may actually be a sign that the economy is beginning to recover. Recovery means growth in output, which should mean less unemployment. However, if workers who have been unemployed for a long time, and have therefore stop seeking employment suddenly feel more optimistic about the prospects of getting a job and begin seeking work again, then the nation’s unemployment rate actually rises! How’s that for “silver lining”? The 216,000 additional people added to the list of unemployed may have already been out of work but since they were notactively seeking employment they were not included in last month’s data.

The tricky thing about macroeconomic policy is this:  Monetary and fiscal policies can put billions of dollars into the nation’s banks and households’ and firms’ pockets through tax breaks, government bailouts, subsidies, infrastructure spending and “troubled asset swaps”… but all the money and income in the world will not lead the nation towards full-employment unless the nation’s consumers and producers feel confident. I teach my students that national income is made up of the sum of wages, interest, rent and profit; its spending consists of consumption, investment, government spending and net exports… but without the “big C” of confidence, expansionary policies aimed at increasing employment will come to nought. Confidence, according to John Maynard Keynes, is an animal spirit, a trait of humans beyond the assumption of rational behavior. Until confidence is restored, America’s output and employment levels will remain low.

Liquidity preference, loanable funds, and Niall Ferguson (wonkish) – Paul Krugman Blog – NYTimes.com

Below is the loanable funds market at its current equilibrium, according to Krugman (I is investment demand for funds, S is the supply of loanable funds):

In Krugman’s words:

In effect, we have an incipient excess supply of savings even at a zero interest rate. And that’s our problem.

So what does government borrowing do? It gives some of those excess savings a place to go — and in the process expands overall demand, and hence GDP. It does NOT crowd out private spending, at least not until the excess supply of savings has been sopped up, which is the same thing as saying not until the economy has escaped from the liquidity trap.

In AP Macroeconomics, we teach that deficit-financed government expenditure decreases the supply of loanable funds as savers take their money out of commercial banks and invest in the bond market due to the attractive interest rates on government debt. Less funds available for the private sector drives up interest rates and crowds out private investment.

If the economy is producing close to the full-employment level and interest rates are positive, the decrease in supply of loanable funds can indeed drive up equilibrium interest rates and lead to the “crowding-out” of private investment. Krugman points out in this article that when the economy is at the “zero-bound” (i.e. when nominal interest rates are as low as they can go) and the quantity supplied of savings is still greater than the quantity demanded for investment, the government can effectively borrow from the public, decreasing the supply and correcting the surplus of savings without driving up interest rates in the private market. Put another way, the equilibrium interest rate is below zero, but the “zero-bound” acts as a price floor in the loanable funds market, resulting in a surplus of savings.

Government borrowing crowding out private investment is not something we can worry about during a recession, when low confidence and expectations have driven the supply of savings up and the demand for investment down. Public spending will divert funds from the private sector to the public sector, that’s true. But in today’s case, savings are sitting idle in the private sector, so government borrowing is putting those fund to use when the private sector has failed to do so.

Discussion Questions:

1. Why does the supply of loanable funds (S in the graph above) slope upwards? Why does the demand for loanable funds (I in the graph) slope downwards?
2. Deficit financed government spending decreases the supply of loanable funds. Why?
3. Crowding-out is not the only possible down-side of deficit spending by the government. What are some other long-term effects of governments running budget deficits year after year?

The Fed should focus on deflation | The greater of two evils | The Economist

Deflation: a decrease in the general price level of goods and services of an economy. Sounds great, right? Lower prices mean the purchasing power of our income increases, making the “average” person richer! On the surface, it could be concluded that deflation may actually be a good thing. And in some cases, it is!

If prices of goods are falling because of major technological advances (think of the price of cell phones and laptop computers over the last 20 years) or because of massive improvements in the productivity of labor and capital (think of the price of manufactured consumer goods during the Industrial Revolution), then deflation could be considered a sign of healthy economic growth. Put in terms an IB or AP Economics student should understand, a fall in prices caused by an increase in a nation’s aggregate supply is good, since it is accompanied by greater levels of employment and higher real incomes. But if the fall in prices is caused by a decline in spending in the economy (in other words, by a decrease in aggregate demand), the consequences can be catastrophic.

It just so happens that the United States, Great Britain, and my own home of Switzerland are all faced with demand-deficient deflation at this very moment. I’ll allow the Economist to elaborate:

…With unemployment nearing 9% (in the United States), economic output is further below the economy’s potential than at any time since 1982. This gap is likely to widen. House prices are not part of America’s inflation index but their decline is forcing households to reduce debt , which could subdue economic growth for years. As workers compete for scarce jobs and firms underbid each other for sales, wages and prices will come under pressure.

So far, expectations of inflation remain stable: that sentiment is itself a welcome bulwark against deflation. But pay freezes and wage cuts may soon change people’s minds. In one poll, more than a third of respondents said they or someone in their household had suffered a cut in pay or hours…

Does this matter? If prices are falling because of advancing productivity, as at the end of the 19th century, it is a sign of progress, not economic collapse. Today, though, deflation is more likely to resemble the malign 1930s sort than that earlier benign variety, because demand is weak and households and firms are burdened by debt. In deflation the nominal value of debts remains fixed even as nominal wages, prices and profits fall. Real debt burdens therefore rise, causing borrowers to cut spending to service their debts or to default. That undermines the financial system and deepens the recession.

From 1929 to 1933 prices fell by 27%. This time central banks are on the case. In America, Britain, Japan and Switzerland they have pushed short-term interest rates to, or close to, zero…

…inflation is easier to put right than deflation. A central bank can raise interest rates as high as it wants to suppress inflation, but it cannot cut nominal rates below zero… In the worst case, rising debts and defaults depress growth, poisoning the economy by deepening deflation and pressing real interest rates higher….Given the choice, erring on the side of inflation would be less catastrophic than erring on the side of deflation.

Discussion Questions:

1. Deflation poses several threats to an economy that is otherwise fundamentally healthy, such as the United States’. What are some the threats posed by deflation?
2. The expectation of future deflation can have as equally devastating effect. Why is this?
3. What evidence does the article put forth that an economy experiencing deflation may eventually “self-correct”, meaning return to the full employment level of output in the long-run?
4. Why don’t governments and central banks just sit back and let the economy self-correct? In other words, why are fiscal and monetary policies being used so aggressively by the US, Great Britain and Switzerland during this economic crisis?

Deflation or Inflation:Watch the video below, see if gives you any clues as to the causes and effects of deflation. What do you think John Maynard Keynes would say in response to the deflationary fears expressed in the Economist article?

Economic View – A Dose of Skepticism on Government Spending – NYTimes.com

We all understand that fiscal stimulus is one of the tools that governments can use to increase the level of economic activity during a recession. The fiscal medicine can be delivered in one of two ways. The government can tweak the tax systems to boost incentives to spend and work or it can increase government spending. One tool that we can use to evaluate the merits of these two policies is to compare the relative multipliers that relate to government spending and taxation.

The multiplier is the key component of Keynesian theory and shows the possibility of a given increase in injections, e.g. government spending, investment and exports, increasing aggregate demand by more than the initial value. This logic fits with our understanding of the circular flow where say increased government spending will lead to increased derived demand for other products, and increased demand for labour. Workers will spend additional wages on other products which leads to further increases in aggregate demand. This flow on effect can be diluted by withdrawals from the system such as taxation or savings.

Greg Mankiw wrote an excellent analysis of this issue in the New York Times in Janurary. “A dose of skepticism on government spending”

An essential skill for IB and AP Economics students is to be able to evaluate the effectiveness of Keynesian  demand-side policies as well as classical supply-side policies, both fiscal and monetary. An understanding of multipliers can improve a student’s ability to evaluate fiscal policy. Greg writes:

“Economics textbooks, including Mr. Samuelson’s and my own more recent contribution, teach that each dollar of government spending can increase the nation’s gross domestic product by more than a dollar. When higher government spending increases G.D.P., consumers respond to the extra income they earn by spending more themselves. Higher consumer spending expands aggregate demand further, raising the G.D.P. yet again. And so on. This positive feedback loop is called the multiplier effect.

In practice, however, the multiplier for government spending is not very large. The best evidence comes from a recent study by Valerie A. Ramey, an economist at the University of California, San Diego. Based on the United States’ historical record, Professor Ramey estimates that each dollar of government spending increases the G.D.P. by only 1.4 dollars. So, by doing the math, we find that when the G.D.P. expands, less than a third of the increase takes the form of private consumption and investment.”

This low multiplier effect implies that any government spending must be used in an effective manner where it will increase the long-term productivity of the country. During a “jobs think-tank” recently in New Zealand, a media release announced an idea of the government spending a vast sum of money to develop a walking track from one end of the country to the other. Would this lead to increased tourism? How much money would these hiking visitors spend? Would it create more jobs?

Should we therefore expect that tax cuts will lead to a greater increase in GDP through the feedback loop compared to government spending? Well, we have to remember that not all tax cuts will be spent immediately, according to the marginal propensity to consume. In a recession some workers will be pessimistic about the future and save the money. Will tax cuts compensate workers who are working shorter hours? Greg suggests that tax cuts might actually be more potent than government spending according to current research.

“Textbook Keynesian theory says that tax cuts are less potent than spending increases for stimulating an economy. When the government spends a dollar, the dollar is spent. When the government gives a household a dollar back in taxes, the dollar might be saved, which does not add to aggregate demand.

The evidence, however, is hard to square with the theory. A recent study by Christina D. Romer and David H. Romer, then economists at the University of California, Berkeley, finds that a dollar of tax cuts raises the G.D.P. by about $3. According to the Romers, the multiplier for tax cuts is more than twice what Professor Ramey finds for spending increases.

Why this is so remains a puzzle. One can easily conjecture about what the textbook theory leaves out, but it will take more research to sort things out. And whether these results based on historical data apply to our current extraordinary circumstances is open to debate.”

So the current research indicates that one-dollar of tax cuts can increase G.D.P by $3 compared to an additional dollar of government spending increasing GDP by $1.40. But why is there such a large difference? Is this related to the arguments about the efficiency of increased government spending? The verdict is still out and we may need to wait till the next global recession to find out.

Below is a picture of the aptly named Bridge to Nowhere located in the central North Island of New Zealand. It was built by the government in a spending splurge in the 1936 to open up land in the area. The land is now no longer fertile or accessible and all access to the area is cut off except for this concrete relic. The area is now popular with trampers.

Discussion Questions:

1. How do economists calculate the multiplier?
2. What are leakages from the circular flow that reduce the multiplier effect?
3. Explain the link between the accelerator model and the multiplier.
4. What would multipliers for other injections such as export receipts or investment look like? Would they be higher or lower than multipliers for taxation or government spending?
5. Evaluate the effectiveness of fiscal stimulus to increase the level of economic activity.

Economists see financial bailout as necessary – Yahoo! News

Economists in the US are calling this week’s bailout of numerous US companies a necessary step in ensuring that no permanent harm is caused to the financial system and that we do not head into a deep recession.

The Treasury Department under the leadership of Henry Paulson is currently asking congress to move quickly on a bill that would provide $700 billion to the Department to buy up much of the bad debt that many financial institutions have incurred over the past years. Where’s this money going to come from? Since it doesnt look like the Bush Administration will be pushing for increased taxes anythime soon, Congress will have to borrow the money. 

Though most economists are agreeing that this is a necessary step in ensuring the integrity of the economy, I believe that it is important to look at how this additional debt may effect our government and economy in the future. So lets start with some numbers. The following statisitics are taken from the above article.

The deficit for this budget year, which ends on Sept. 30, is expected to rise to $407 billion, a figure that is more than double the $161.5 billion imbalance for 2007, reflecting what the economic slowdown and this year’s $168 billion economic stimulus program are already doing to the government’s books.

The Bush administration is estimating that the deficit for the budget year that begins Oct. 1, which will cover the new president’s first year in office, will hit $482 billion, a record in dollar terms.

And that forecast doesn’t include the $200 billion the administration committed to spending two weeks ago when it took over the nation’s two biggest mortgage companies, Fannie Mae and Freddie Mac.

And it doesn’t have any of the $700 billion the administration is seeking to soak up the bad mortgage-backed securities that have been at the heart of the severe credit crisis the country has been struggling with since August 2007.

The legislation the administration is now seeking to authorize the financial system bailout, according to a draft obtained by The Associated Press, would boost that debt limit to $11.3 trillion, up another $700 billion.

It is the rapidly rising debt that is cause for concern. The government is already spending more than $400 billion a year just to pay interest on the national debt. The higher that debt goes, the higher the government’s borrowing costs and the less it has to spend on other programs.

Discussion Questions:

1. What impact does the knoweldge that the government will bailout struggling financial firms have on investors willingness to take risks?
2. Should the government intervene in these finacial markets or leave the “invisble hand” to its own devices?
3. What are the opportunity costs associated with this decision?
4. What are some short term and long term implications of this bailout?

Judging by today’s headlines, things aren’t looking too hot for the US economy:

• Job losses, unemployment both worse than forecast – Apr. 4, 2008
• Dollar slips against euro, yen on jobs – Apr. 4, 2008
• BBC NEWS | Business | Oil price edges up on Opec stance
• FT.com / Asia-Pacific / China – US economy is ‘down sharply’, Paulson says
• Bernanke Nods at Possibility of a Recession – New York Times

From the last article:

In his bleakest economic assessment to date, the Federal Reserve chairman, Ben S. Bernanke, said Wednesday that the American economy could contract in the first half of 2008, meeting the technical definition of a recession, and he encouraged Congress to help homeowners caught up in the mortgage crisis.

For the first time during his three years in the job, Bernanke has admitted we could be in a recession, defined as two consecutive quarters of negative GDP growth. By June, we could very well have experienced just such a decline in output; every central banker’s nightmare!

The source of America’s economic woes? Weak housing market. In fact, house prices have fallen around 10% nationwide over the last 12 months. To understand why, we need to recall the basic microeconomic principles of supply and demand. Quite simply, too many homes were built over the last decade, as low interest rates and optimism about the continued strenght of the housing market (rooted, of course, in the irrational exuberance about the economy as a whole) led builders to expand the suburban sprawl like never before, anticipating growing demand forever into the future. Problem was, demand couldn’t keep up with supply, and now the price is starting to reflect this basic economic principle.

To make things more complicated, many home buyers over the last seven years should never have been given loans based on their credit histories and household incomes. Many of these buyers were thus given “sup-prime” loans, many with adjustable interest rates, which means that today people who were too poor to get a normal loan four years ago are seeing their monthly payments increase just as the economy is slowing down. Rising unemployment puts downward pressure on wages, and inflation (caused by rising energy and commodity prices) forces poor homeowners to allocate more of their wages towards food and electricity, making it doubly hard to make their monthly mortgage payments.

The outcome is predictable: foreclosures. Banks that made loans to uncreditworthy buyers are now taking the houses back and putting them on the market for really low prices, putting even more downward pressure on all home prices. Since their homes make up the majority of Americans’ wealth, and since wealth and disposable income are the main determinants of consumption, inflation and falling home prices both lead to huge decreases in consumption.

The cycle continues: declines in household consupmtion signals to firms that it’s a bad time to invest, so investment spending declines. As consumption and investment fall, aggregate demand shifts in, causing output and employment to fall, hence our current recession.

“It now appears likely that real gross domestic product, or G.D.P., will not grow much, if at all, over the first half of 2008 and could even contract slightly,” he said. “We expect economic activity to strengthen in the second half of the year, in part as the result of stimulative monetary and fiscal policies.”

For now, however, judging by today’s headlines, conditions will continue to worsen for the American worker, homeowner, consumer and firm.

Promotional Fax Mistaken for Bomb Threat – washingtonpost.com

I don’t know, but I would say the American people are a little on edge these days. What does it say about our society when a paranoid bank employee receives a fax and calls in the bomb squad? The arrival of the threatening fax coincided with the arrival of a “suspicious” package, escalating the fears of the terrified bank staff. Turns out the fax was from the corporate office, and the package contained some paper files, but by the time police figured it out 15 local businesses and a nearby day care’s 30 children had been evacuated from the area!

Okay, so this story may not appear to have much to do with our Econ course… or does it?

Discussion questions*:

1. What impact might mass paranoia about terrorism have on the macro economy? Explain.
2. Would the free market provide the security and protection needed to ensure a healthy and safe environment for investment? Why or why not?
3. What is the term for a service or product that provides spillover benefits for society but which is under-provided by the free market (such as a police force)?
4. Do you think the bank employees were right to be frightened by the threatening fax? Is their fear rational or irrational given the political and social climate in America today?

*From now on, most of the posts on this blog will include discussion questions. These are meant to help students start their own discussion about the issues raised in the posts and how they connect to our economics course. Posts like this one are tagged with a category, and next year when we get to a particular topic in our Econ course, students will be asked to find a past post from that category on the blog, read it and post their comments. This will become a part of students’ grades. To see how the blog will graded, click here.
