Economics Goes Viral



Nothing gets me more excited than getting people with no formal background in economics to see how econ fits in their everyday life. In light of that, imagine my surprise when my good friend Eva Funderburgh, a professional sculptor, wanted to share some economics with me! Apparently she’s not the only one spreading the video above, because, as of this writing, the viral video above created by TV producer/director John Papola and economist Russ Roberts has already received over half a million views on YouTube! Papola and Roberts’ video does a wonderful job creating a new way to take a traditional economic discussion and make it more approachable and entertaining to a much wider audience. In my mind, every economics student should watch the video, and hopefully share it with others as well. For those with a little more time, NPR has put together a very entertaining look at how the project came to be.

The economic thoughts and ideas represented in the video are spot-on, and the lyrics are a fair presentation of the differing schools of thought. While the deeper issues behind the video are much larger than anyone could take on in a single blog post, I do see a place that might deserve a small footnote. I do not mean to take anything away from all the great work that went into this video, but I feel that Keynes’ introduction might deserve a bit of further discussion:

“John Maynard Keynes, wrote the book on modern macro”

Depending on how you define “modern,” an economist who died more than sixty years ago may no longer fit the bill. I think it is totally appropriate to say that Keynes wrote the book on 20th century macroeconomics, but the research frontier of the field is moving beyond his ideals. Starting in the 1970s, some members of the field have explored more complicated models based on critiques of Keynes’ work by Nobel Prize winners Robert Lucas and Milton Friedman, among others. These researchers worry that some of Keynesian economics’ critical assumptions oversimplify the world and make the model invalid. While Keynesian theory is still widely taught today and used by many people advising current policy decisions, some macroeconomists now advocate for models that are built on individual decision making, rather than only analysis based on total expenditure.

These “micro-founded” macro models seek to explain trends in data that defy Keynesian theory. One difference between these schools of thought centers on if household consumption decisions can change in response to fiscal and monetary policies. For example, Keynesian theory assumes that policy does not affect the fraction of net income spent and saved and that the amount of economy-wide consumption will simply change by the product of the tax’s size and the proportion of a household’s after-tax income spent on consumption (often referred to as the marginal propensity to consume, or MPC).

On the other hand, extensions of the micro-founded model proposed independently by Frank Ramsey, Dave Cass, and Tjalling Koopmans suggest that if the government were to lower taxes and give households more money, consumers may choose to change their entire consumption-spending decision based on having larger net income, thus resulting in a new MPC. Whether or not the assumptions made by Keynes are valid (or small enough to be overlooked) is a matter of personal opinion, but as the research horizon of economics extends more than half a century after his writing, it appears that there is still work to be done before macroeconomics can perfectly explain an entire real-world economy.

Discussion Questions:

1. Why should we “fear” booms and busts? Why might booms and busts be good? Is there an “optimal” level of economic fluctuation?

2. Who do the bartenders “Ben” and “Tim” represent in the video? Why are they pouring liquor? What does the liquor represent?

3. The chorus of the rap has Keynes saying “I want to control markets” and Hayek saying “I want to set [markets] free.” Is either of those positions right or wrong in all circumstances? Under what circumstances is more government intervention in markets warranted, and under what circumstances should the government stay out as much as possible?

4. What are the critiques that Keynes offers of Hayek? What are the criticisms that Hayek proposes about Keynes? Does one side seem to have a much stronger argument than the other, or do they both suggest that the theory’s view of the world is still incomplete?

5. Do you think the financial crisis of the past few years was caused by people who thought more like Keynes or more like Hayek? Why?

Fed Chairman Bernanke Chosen as Time Magazine's Person of the Year



In a December 16, 2009 article, Michael Grunwald details the reasoning behind Time Magazine’s choice of Federal Reserve Chairman Ben Bernanke for Person of the Year. The article delves into Bernanke’s background such as his working class roots and the consensus that he is “a leading scholar of the Great Depression.” It also details the unique nature of the crises of 2007-2008 to which the Fed responded in creative and beneficial ways.

Chairman Bernanke is currently awaiting a Senate vote to be confirmed for another term as Fed chairman. The vote is being held up by a Senator from the far left and another from the far right. The Time article is largely critical of those who oppose Bernanke, portraying them as nitpicky demanders of perfection who fail to realize that the Federal Reserve’s actions over the past two years most likely “prevented an economic catastrophe.” It is apparent that the Fed, like most people caught up in benefiting from the bubbles of those years, took too long to recognize the danger signs. Yet, the desire to criticize and rein in the Fed’s power now that the crises are largely history is short-sighted and will be harmful to long-run inflation rates. Most economics textbooks cover the extensive research that shows that greater central bank independence goes along with more stable and lower inflation rates.

As Bernanke is quoted in the article, "We came very, very close to a depression ..." That is because in the fall of 2008, the collapse of the financial sector and asset prices looked remarkably similar to the events that marked the start of the Great Depression. However, thanks largely to the bold actions of Bernanke’s Fed, the US experienced a severe recession rather than a depression. That distinction is significant and reason enough for the awarding of Time Magazine’s honor. Grunwald’s article gives evidence that Bernanke’s knowledge and research into the Depression made him the perfect man to hold one of the most powerful positions for influencing the world economy. As written by Grunwald, “He didn't just reshape U.S. monetary policy; he led an effort to save the world economy.”

Admittedly, the severe recession has caused significant hardship to billions of people. However, based on economists’ consensus definition of recession, the US economy has been in recovery and thus out of recession for several months now. Indeed, the figure to the right shows a picture of an economy that will most likely experience positive net job creation in coming months. Such positive net job creation has not occurred since the recession began in December 2007. This scenario looks much rosier than could have been hoped for back in the fall of 2008. This is an important reason why Bernanke is expected to be confirmed for another term:

Finally, Bernanke’s critics need to understand that macroeconomics is not a true science. Despite the mathematical rigor required to publish articles in the field, macroeconomists cannot perform true experiments with a nation’s economy. Therefore, there is no comparison “control group” of a US economy run by someone who chose not to bailout AIG or who refused to dramatically expand the Federal Reserve’s balance sheet with risky assets. We will never know with any respectable precision what might have happened if it had not been for Bernanke’s bold leadership.

Perhaps someday a scientific genius will invent a time machine so that Bernanke’s critics can go back to the early 1930s to experience a collapsed economy. Most economists agree that the experience of those years is the best counterexample to show what we would have experienced without bold action by the Fed and our elected officials. Let the critics be reminded that the demand for perfection is all too often the enemy of good governance.

Discussion Questions

1. What is your reaction to Time Magazine’s choice of Federal Reserve Chairman Ben Bernanke for Person of the Year? Why?

2. Suppose that you were able to cast a vote in the Senate on Bernanke’s reappointment. How would you vote? Why?

3. Imagine you were currently chairperson of the Fed. What, if anything, would you be doing differently?

4. Do you approve or disapprove of the movement to rein in the power of the Federal Reserve? Explain.

Recession-proof



Doomsayers are coming out of the woodwork en masse as 2008 ended during a dismal economic downturn. With consumer confidence at an all-time low, the financial industry shell-shocked as grand, monolithic companies crumbled all around, and nearly 2 million jobs lost in the past year, the end looks nigh indeed.

But before you don your sandwich boards and raise high your signs, things may not be as bad everywhere as they seem.

The economy rises and falls in what's called a business cycle. Some years are relatively prosperous with rapid economic growth and expansion while other years see the economy contract or stagnate. These fluctuations last over periods of years and their timing is largely unpredictable.

Some firms stick with the general trend of the market, their business conditions weakening when the market weakens, strengthening when the market recovers. These are procyclical firms. Others, countercyclical firms, do the reverse; their business conditions weaken when the times are good, and strengthen when times are bad. There are still other industries that don't depend on how the economy is doing at all.

So, while the bankruptcies and bailouts get the boldest headlines these days, here's a brief list of industries that are doing just fine.
  • The funeral services industry depends more on long-term trends such as aging populations and baby booms rather than on the twitching of the stock ticker. And of course, it also helps that their services are always in demand.
  • The entertainment industry is another good example. Revenue from concerts and movies have stayed strong during this economic downturn. Faced with gloom and doom, many find the few hours of escapism well worth the price of admission.
  • Discount stores, most notably Wal-Mart, are attracting cash-strapped customers looking to get the most out of their money.
  • As jobs get scarcer, going back to school makes a lot of sense for those looking to weather the fierce competition in the job market and to improve their skills and credentials. According to the Labor Department, the education industry has added 9,800 jobs in November.
Discussion Questions

1) What are other examples of procyclical industries? Countercyclical industries?

2) During the economic boom of the '90s, how did countercyclical industries do? Did more people drop out of school and enter the labor force? Did Wal-Mart suffer a decrease in sales?

3) Do you think prices, in general, drop during a recession? Why or why not?

4) How much do you think countercyclical firms contribute to an economy's eventual recovery?

Should the Government Bail Out the Auto Industry?



America's Big Three—General Motors, Chrysler, and Ford—are in big trouble. Sales from the not-so-fuel-efficient fleet of American-made vehicles had already suffered considerably because of high gas prices even before the financial crisis began to get serious in September of 2008. Faced with undesirable terms in private credit markets, the Big Three are now turning to the government for financial assistance. The House passed a bill to rescue the Big Three car companies with $15 billion in emergency loans on Wednesday, December 10, but the Senate abandoned the plan the day after. Should the government bail out the auto industry?

Those in favor of the bill argued that the rescue plan can prevent the loss of 500,000 jobs in the auto industry. Job losses in the auto sector would most likely have spillover effects in other sectors. As auto workers lose their jobs, they would consume fewer goods and services, negatively affecting industries in retail, health care, and financial services. With unemployment already rising, supporters of the bailout argued that keeping auto workers in their jobs is much easier than creating new jobs for them.

Opponents of the bill compared the bailout to the inefficiencies generated by government subsidies and tariffs. Many companies face financial problems—why should the government save the Big Three and not the others? Poor performance is typically a good signal that a company should change how and what it produces. A partial government takeover of American auto companies will not ensure that the firms will start producing vehicles that people want to buy. A bailout, according to critics, will simply prolong the inevitable: the consolidation of the American auto industry, the large number of layoffs that come with it, and the migration of workers from autos to more profitable industries.

Discussion Questions

1. What is the role of labor unions in contributing to the financial problems facing the Big Three? In particular, how well do the wages reflect the productivity of the workers in the Big Three? Click here to read more.

2. Do you think the problems faced by the Big Three stem primarily from the recent financial crisis or from longer-term decisions about what types of vehicles to produce and how to produce them?

3. Some suggest that another reason leading to the failure of the Big Three is that American consumers prefer cars made by foreign companies, such as Toyota and Honda, to cars made by American-owned companies. How does the market of foreign-made cars affect the demand for American cars?

4. Foreign-owned automakers, like Toyota and Honda, operate production facilities in the United States and employ American workers. How would these firms be affected by a bailout of the American-owned Big Three? How will foreign auto firms with operations in and outside of the United States be affected if one or more members of the Big Three were allowed to fail?

5. How do the loans compare with tariffs in foreign trade? What advantages and disadvantages do they share in common?

6. What would happen to the broader economy if the plants closed and workers became laid off? What might these workers do to find new employment? Which sectors would employ them?

Loss Aversion and the Housing Market



For many people, the pain of losing $500 outweighs the pleasure of gaining $500. As Austan Goolsbee points out in a recent New York Times column, this aversion to loss is especially acute when it comes to selling real estate. People are stubborn about selling a house for less than they paid for it. If selling at prevailing market prices means accepting a significant loss, some people refuse to sell at all, or else base pricing decisions not on what they would willingly pay to buy a similar house today, but rather on what they paid for the house when they bought it. As a result, sellers who bought houses during the peak of the housing boom will list their properties for a higher price than nearly identical homes purchased earlier on at lower prices. At worst, the strong reluctance to sell at a loss leads to a prolonged freeze in the housing market, with many homes listed for sale at prices that buyers will not pay. Since people who sell a house often go on to purchase another, loss aversion can contribute to weaker housing demand and prolong the housing slump.

The housing correction in the U.S. continues to reduce house prices in many regional markets. The correction raises the risk of a downturn in the U.S. economy. As house prices decline (other things being equal), household wealth declines, and consumption expenditures decrease. The shock to consumption spending may contribute to slower growth or even a recession. As Goolsbee points out, loss aversion in the housing market adds to the gloomy outlook for the broader economy. The reduction in housing-market transactions affects the consumption of durable goods and increases the costs associated with switching jobs. Read Goolsbee's column to find out more.

Discussion Questions

1. According to the article, what fraction of home buyers are moving within a metropolitan area? How will seller reluctance to lower prices during a housing slump affect the number of future buyers in a local housing market?

2. Suppose a beet farmer arrives at the farmers' market only to discover that other beet farmers are selling identical beets for less than he had intended to sell his own beets. He is likely to succumb to competitive forces and sell his beets at the prevailing price. Why are house sellers, unlike beet farmers, unwilling to lower their prices? Does it have to do with characteristics of the sellers or characteristics of the markets?

3. What are durable goods? Why would this type of housing-market freeze impact sales of durable goods? Why do you think the ups and downs of durable-goods sales are closely aligned with the ups and downs of the business cycle?

4. Frictional unemployment refers to the relatively short spells of unemployment associated with finding and transitioning to a new job. For example, a recent college graduate searching for her first job or a banker transitioning between jobs in different areas will be frictionally unemployed until they start at their new positions. How might a prolonged housing freeze increase frictional unemployment? To what extent might a housing freeze cause people to stay in jobs they would otherwise leave?
