The balance-of-trade hobbyhorse

Filed under: Economics, Government, Media — Tags: , , , , — Nicholas @ 03:00

Don Boudreaux doesn’t have much sympathy with people who agonize over or — worse — set their national economic policies based on the balance of trade:

No concept in economics is responsible for more confusion and policy mischief than is the so-called “balance of trade.” The many fallacious beliefs about a trade deficit include the notion that –

– aggregate demand drains from each economy that runs a trade (or current-account) deficit, thus causing overall employment to fall in each country that runs a trade deficit;

– the GDP of a country that runs a trade deficit is lowered by that trade deficit;

– the denizens of a country that runs a trade deficit spend too much on consumption and save too little;

– a trade deficit is evidence of poor policy in any country that runs such a deficit;

– a country’s trade deficit would be ‘cured’ if only the people of that country were to save more or to buy fewer imports;

– a trade deficit in the home economy is evidence of ‘unfair’ trade practices by that country’s trading partners;

– a trade deficit means that each country that runs one is “losing,” and that to “win” at trade means running a trade surplus (or, at least, to not run a trade deficit);

– a trade deficit run by the home economy means that that economy’s trading partners who have trade surpluses are being enriched at the expense of the people in the home economy;

– a trade deficit necessarily makes the citizens of any country that runs one more indebted to foreigners;

– a trade deficit involves a net transfer of capital or asset ownership from citizens of each country that runs a trade deficit to citizens of countries that run trade surpluses;

– each dollar (or each yen, or each euro, or each peso, or each pound, or each you-name-the-currency) of a country’s trade deficit today means that the people of that country must sacrifice that much consumption sometime in the future;

– bilateral trade deficits have economic meaning and relevance;

– a trade deficit is something that should be “fixed” – that is, reduced or eliminated – through government policy, including especially through trade restrictions.

None of the above-listed beliefs about trade deficits is supportable. None. Not one. Not in the least. Each and every one of these beliefs is easily refuted with either basic economics or, in many cases, with simply a clarification of the definitions of terms and concepts used in national-income accounting. And yet these – and no doubt other – false beliefs about trade deficits (and about the so-called “balance-of-payments” generally) are widespread and spill daily from the mouths and keyboards of politicians, pundits, professors, and propagandists.

The belief that trade deficits cause economic problems in countries that run them – and that trade deficits necessarily reflect poor policies or profligacy by the people of those countries – is the economic equivalent of, say, the belief that the world is ruled by sorcerers who ride fire-breathing dragons and who marry their daughters off to centaurs. Both sets of beliefs are pure madness, yet one of them serves as the basis for real-world policies.

The Solow Model and the Steady State

Remember our simplified Solow model? One end of it is input, and on the other end, we get output.

What do we do with that output?

Either we can consume it, or we can save it. This saved output can then be re-invested as physical capital, which grows the total capital stock of the economy.

There’s a problem with that, though: physical capital rusts.

Think about it. Yes, new roads can be nice and smooth, but then they get rough, as more cars travel over them. Before you know it, there are potholes that make your car jiggle each time you pass. Another example: remember the farmer from our last video? Well, unless he’s got some amazing maintenance powers, in the end, his tractors will break down.

Like we said: capital rusts. More formally, it depreciates.

And if it depreciates, then you have two choices. You either repair existing capital (i.e. road re-paving), or you just replace old capital with new. For example, you may buy a new tractor.

You pay for these repairs and replacements with an even greater investment of capital.

We call the point where investment = depreciation the steady state level of capital.

At the steady state level, there is zero economic growth. There’s just enough new capital to offset depreciation, meaning we get no additions to the overall capital stock.

A further examination of the steady state can help explain the growth tracks of Germany and Japan at the close of World War II.

In the beginning, their first few units of capital were extremely productive, creating massive output, and therefore, equally high amounts available to be saved and re-invested. As time passed, the growing capital stock created less and less output, as per the logic of diminishing returns.

Now, if economic growth really were just a function of capital, then the losers of World War II ought to have stopped growing once their capital levels returned to steady state.

But no, although their growth did slow, it didn’t stop. Why is this the case?

Remember, capital isn’t the only variable that affects growth. Recall that there are still other variables to tinker with. And in the next video, we’ll show two of those variables: education (e) and labor (L).

Together, they make up our next topic: human capital.

Structural Unemployment

Published on 8 Nov 2016

Unemployment comes in many forms. Sometimes, like we saw with short-term, frictional unemployment, it can actually indicate a healthy, growing economy. But what about persistent, long-term unemployment? That’s not so good.

When a large percentage of those who are considered unemployed have been without a job for a long period of time and this has been true for many years, it’s considered structural unemployment.

Structural unemployment can result from shocks to an economy that drastically alter the labor market. These shocks are not all bad – the rise of the Internet is one such example. Regardless, it can take a while for an economy to adjust to big changes.

These adjustments tend to happen faster in the United States than in Europe. This is most likely due to differences in labor regulations, and how those regulations affect a country’s ability to respond to shocks.

The United States’ employment law known as the “at-will doctrine” makes it so that an employee can quit, or an employer can fire, at any time for any reason. It’s legally much harder to terminate an employee in many European countries. This makes hiring riskier in Europe, resulting in a less dynamic labor market that isn’t able to quickly respond to shocks.

As you might guess, structural unemployment tends to count for a higher percentage of total unemployment in Europe than in the United States. This remains one of the most serious issues facing many European economies today.

Frictional Unemployment

Finding a job can be kind of like dating. When a new graduate enters the labor market, she may have the opportunity to enter into a long-term relationship with several companies that aren’t really a good fit. Maybe the pay is too low or the future opportunities aren’t great. Before settling down with the right job, this person is still considered unemployed. Specifically, she’s experiencing frictional unemployment.

In the United States’ dynamic economy, this is a common state of short-term unemployment. Companies are often under high levels of competition and frequently evolve. They go out of business or have to lay off workers. Or maybe the worker quits to find a better position. In fact, millions of separations and new hires occur every month accompanied by short periods of unemployment.

Frictional unemployment helps allocate human capital (i.e. workers) to its highest valued use. Hopefully, workers are similarly finding themselves with more fulfilling jobs. Even when it’s caused by an event such as a firm going out of business, frictional unemployment is a normal part of a healthy, growing economy.

Defining the Unemployment Rate

How is unemployment defined in the United States?

If someone has a job, they’re defined as “employed.” But does that mean that everyone without a job is unemployed? Not exactly.

A minor without a job isn’t unemployed. Someone who has been incarcerated also isn’t counted. A retiree, too, does not count toward the unemployment rate.

For the official statistics, you have to meet quite a few criteria to be considered unemployed in the U.S. For instance, if you’re without a job, but have actively looked for work in the past four weeks, you are considered unemployed.

In times of recession, when people are faced with long-term unemployment and lots of discouragement, the official rate might not count some of the people that you would otherwise consider unemployed.

This video will give you a clear picture of how the unemployment rate is defined and build a foundation for further understanding this important facet of labor markets.

Is Unemployment Undercounted?

You may recall from our previous video that to be counted in the official unemployment rate in the U.S., you have to be an adult without a job and have actively looked for work within the past four weeks. That means that if someone has given up looking for a job, even if they want one, they are no longer counted under the official definition.

Does this mean that unemployment is undercounted? In other words, is the unemployment rate in fact higher than is reported?

Some have claimed this to be the case. However, unemployment is a tricky statistic. It’s important to consider that adults without jobs can fall into different categories. Many retirees, for example, are willing to leave retirement and take a job for the right price. If we are counting people that aren’t actively looking for employment, shouldn’t the retirees also be considered unemployed?

The simplest solution to this conundrum is to only count unemployed adults actively seeking work.

But what about discouraged workers — those who are unemployed and have not sought work in the past four weeks, but have sought work in the past year. Should we consider them in our calculations?

There are actually six different unemployment rates measured by the U.S. Bureau of Labor Statistics. The various rates have less and more stringent criteria. The official rate, called U3, falls somewhere in the middle. Another rate, called U4, does include discouraged workers in its calculation. All six rates follow a similar track over time.

So while the official unemployment rate may not be perfect, it does provide us with a good indicator of the state of the labor market and where it’s headed.

Tyler Cowen: The Economics of Choosing the Right Career

Published on 11 Oct 2016

As many who entered the labor market following the Great Recession know all too well, graduating with a college degree does not mean you’ll easily fall into a good career. Four-year college graduates with entry-level jobs actually earned more in 2000 than they’re earning today and student loan debt burdens are higher than ever.

Does this mean you should skip college or drop-out? Not necessarily. Unemployment is still lower for those with undergraduate and higher degrees. However, understanding the economics behind the labor market will make finding a career a more manageable task.

The labor market in the United States has undergone many changes in the past few decades. Whereas we once had many manufacturing jobs that required little training or specialized skills, the labor market today demands more people who can work with computers and information technology.

Choosing a good career requires planning beyond getting a college education. You’ll want to carefully consider the career options available for your major, as well any specialized skills you’ll need to build outside of the classroom.

It’s also essential to understand how supply and demand affect your career options. How many people are also choosing that major vs. how many employers are looking for those skills? Is a particular career path susceptible to being replaced by a machine? What about outsourcing in the global labor market? What about laws and regulation – does it require an occupational license?

There’s a lot to think about! Choosing a career is a huge decision and understanding how supply and demand rule the labor market will help you better navigate your future.

Econ Duel: Rent or Buy?

Published on 13 Sep 2016

Owning a home is a huge part of the American Dream. But is the dream of home ownership really all it’s cracked up to be?

In this new Econ Duel from Marginal Revolution University, Professors Tyler Cowen and Alex Tabarrok weigh in on the issue. Each representing a side of the home ownership debate, the two professors ask what’s smarter — to rent, or to buy?

On the “buy” side, Tyler Cowen shares the tax advantages of buying a home as well as the effect home ownership has on one’s stability and savings regimen. Does buying a home force us into better savings habits?

Against those arguments, we have Alex Tabarrok, coming down on the “rent” side of the equation.

Among other points, he talks about the real beneficiary of tax breaks (hint: It may not be you!). Along with that, Alex tackles the trials and tribulations of home-buying, in places like San Francisco, New York, or Boston, where a combination of scarce building permits and increased demand drive up home prices. Plus, doesn’t owning a home — and committing a 20% down payment — break the diversification rule of good investing?

All that said, though, here’s the real question that matters — which side are YOU on? Watch and let us know in the comments!

Investing: Why You Should Diversify

Filed under: Economics — Tags: , — Nicholas @ 02:00

Marginal Revolution University
Published on 30 Aug 2016

So far, we’ve been telling you what not to do when investing. Here’s what you should do: diversify.

Don’t put all your eggs in one basket. Definitely, don’t put your investment money solely in your employer’s stock. That’s very loyal, but it’s a terrible strategy. Just think of Enron’s employees. They had huge chunks of their retirement funds in company stock. Upon Enron’s collapse, many employees who were once multimillionaires ended up with almost nothing.

As you can see, diversification is much safer. Diversification reduces risk by spreading your investment across different assets, doing so without reducing potential returns. Plus, modern financial markets make diversification easy. For example, our favorite investment instrument is the low-fee index fund. These funds mimic a large market basket of stocks, like the S&P 500. The sheer variety in the fund is what mitigates the risk. It’s diversification for the win.

A quick reminder, though. Choose an index fund with low fees. Fees may seem trivial, until you watch them eat away at your investment. Imagine this: take a hypothetical $10,000. Invest that in a fund with a 1% fee, and you’ll have roughly $57.5K after 25 years, assuming an average 8% return. Now, invest the same $10K, in a fund with a 0.2% fee.You’ll get roughly $70K over the same quarter-century.

Our point is — when it comes to investing, simple is best. So for example, if your employer offers a 401K, take the offer!

That being said, you might believe that the market is irrational. Anomalous, even.

No worries.

Next time, we’ll tackle behavioral finance to see if you can profit from anomalies, and irrationality.

Who Is More Rational? You or the Market?

We mentioned before that it’s hard to beat the market. And you shouldn’t try. But what about market anomalies?

One anomaly is the Momentum Effect — where past stock performance predicts future performance, at least a bit. As an example, portfolios with past winners tend to outperform the market in the medium term. Why is that? The market sometimes under-responds to changes in information. Thus, some stocks can lag, even if rationally, they shouldn’t. This is why picking past winners can generate some profit, though the profit’s usually small.

There are also other anomalies, like the Monday Effect, where stocks fall more on Mondays. Or, there’s the January Effect, which says that stocks surge higher in that month. There’s been some evidence for these effects, but these anomalies don’t last.

Despite its flaws, the market is still more rational than you. Don’t forget, you’re probably like most individual traders. You may become overconfident. You may not calculate probabilities that well. And if the market crashes, you’re likely to act more emotionally than you should — just like everyone else.

But don’t just take our word for it — even Warren Buffett agrees! Don’t try to beat the market.

Can You Beat the Market?

On average, even professional money managers don’t beat the market. To show you why, here’s a scenario to consider:

Say we advise you to invest in companies serving the aging US population. Since the percentage of elderly will rise over the coming decades, it makes sense to invest now in products and services that the elderly might need. Sounds logical, right? Wrong.

See, the aging of the US population isn’t a secret. It’s public information. Now, say you acted on the information and did buy stock as we advised. The current price of that stock already reflects information known to the market. Thus, it’s hard to systematically outperform the market, given that everyone else tends to have the same information you do. This is also the main idea behind the efficient market hypothesis.

According to the efficient market hypothesis, the prices of traded assets already reflect all publicly available information.

With information available to buyers and sellers alike, no one has any sustainable advantage over anyone else. This is why even the pros tend not to beat the market. And that aside, even if news did pop up to change the price of an asset, it would be at random and would likely be reflected in the asset price almost immediately. So there’s no reliable way to forecast performance.

As proof of that, take the Challenger space shuttle crash of January 28, 1986. Within minutes of the crash, the news hit the Dow Jones wire service. The stock prices of the major contractors who helped build the shuttle fell immediately. Keep in mind: that was in the 80s. At today’s pace, new information can change stock prices within seconds. This is why stock tips often end up obsolete.

So to sum up — it’s hard to beat the market. You have to accept that.

Still, how should you invest? That’s what we’ll discuss in the next video.

How Expert Are Expert Stock Pickers?

Published on 16 Aug 2016

In this first video in our Personal Finance section of Macroeconomics — and also our new course on Money Skills — we’ll begin to lay out some smart rules for investing.

Today, we’ll tackle Rule 1 — ignore the expert stock pickers.

What’s the basis of that rule? Well, in his 1973 book, A Random Walk Down Wall Street, economist Burton Malkiel made a controversial claim. He claimed that a blindfolded monkey, throwing darts at the financial pages, could select a basket of stocks that would do just as well as a set chosen by the pros.

One of Malkiel’s later students, the journalist John Stossel, set out to test that claim. Stossel did throw darts at the financial pages. The darts landed on 30 companies. Turns out, Malkiel did have it right — the randomly-selected stocks did better than professionally-picked ones.

The point here is, random picking roughly gives you as good results, as trusting the pros. Consider — in most years from 1963-2008, the S&P 500 Index outperformed most of the managed mutual funds. And in a different study, researchers took the top 25% best-performing funds. Two years later, less than 4% of the original set remained in the top quarter. Five years later? Only 1% stuck around.

Basically — past performance doesn’t guarantee future results. Chance often tends to win out.

To show you what we mean, take a hypothetical set of 1000 experts making market predictions. Let those predictions be based on a coin toss. Experts who land heads will say the market will surge this year. Those who land tails say the opposite. At the end of the experiment’s first year, 500 of the 1000 experts will have been right, solely by chance. Now, say the remaining 500 toss again. At the end of the second year, 250 experts will have been right, again by chance. Continue with this logic, and by the end of the fifth year, roughly 32 of the 1000 will have been right, five years running.

Perhaps these 32 will be hailed as geniuses, but remember, they only came about through a coin toss.

So, what’s to conclude from this? Two things.

First, luck and chance matter. In some cases, it can be hard to differentiate luck from skill, as proven by the “genius” 32. Second, no need to spend big bucks on a money manager. After all, the studies prove that random picking often works just as well as professional management.

That said, what if you did have market information? What if you knew something about certain stocks, that made you think they’d do well? Could you beat the market then? That’s what we’ll answer in our next video, when we tackle the efficient market hypothesis. Stay tuned!

The Great Recession

Marginal Revolution University
Published on 9 Aug 2016

There’s already been much discussion over what fueled the Great Recession of 2008. In this video, Tyler Cowen focuses on a central theme of the crisis: the failure of financial intermediaries.

By 2008, the economy was in a very fragile state, with both homeowners and banks taking on greater leverage, many ending up “underwater.” Why did managers at financial institutions take on greater and greater risk? We’ll discuss a couple of key reasons, including the role of excess confidence and incentives.

In addition to homeowners’ leverage and bank leverage, a third factor played a major role in tipping the scale toward crisis: securitization. Mortgage securities during this time were very hard to value, riskier than advertised, and filled to the brim with high risk loans. Cowen discusses several reasons this happened, including downright fraud, failure of credit rating agencies, and overconfidence in the American housing market.

Finally, a fourth factor joins homeowners’ leverage, bank leverage, and securitization to inch the economy closer to the edge: the shadow banking system. On the whole, the shadow banking system is made up of investment banks and various other complex financial intermediaries, highly dependent on short term loans.

When housing prices started to fall in 2007, it was the final nudge that pushed the economy over the cliff. There was a run on the shadow banking system. Financial intermediaries came crashing down. We faced a credit crunch, and many businesses stopped growing. Layoffs ensued, increasing unemployment.

What could have been done to prevent all of this? You’ll have to watch the video to find out.

Four Reasons Financial Intermediaries Fail

Filed under: Americas, Economics, Japan — Tags: , , , , , — Nicholas @ 02:00

Marginal Revolution University
Published on 26 Jul 2016

As we’ve discussed in previous videos, financial intermediaries bridge savers and borrowers. When these bridges crumble, the effects can be disastrous. For businesses, credit shortages can lead to bankruptcy, or layoffs. For individuals, they rely on credit to invest in education or a new home or car. These negative effects show you how crucial intermediaries are to our lives.

Still, what exactly causes failed intermediation? Four answers:

First, insecure property rights. Simply speaking, when you save money at a bank, you expect the ability to pull out your funds when needed. But what if your deposits are frozen? Or confiscated altogether? For instance, in 2013 amidst a financial crisis, the government in Cyprus confiscated bank deposits to help pay down the country’s budget shortfall. You can see how insecure property rights can scare away potential savers.

Second, controls on interest rates. Interest rates are the price of borrowing. Thus, controls on interest rates, often called usury laws, are effectively price ceilings—they set the interest rate lower than the market equilibrium interest rate. With this forced lowering of interest rates, borrowers will want to borrow more, but lenders won’t want to lend. The effect? A lending shortage.

Third, politicized lending. Banks profit by assessing risk, and then loaning, based on that assessment. Banks that excel at assessment succeed. Those poor at it die out. Problems arise when the government intervenes to prop up failing banks, resulting in what we call “zombie banks.” In such cases, intervention undercuts normal competition, and intervention tends to favor banks that are politically connected. In fact, it’s been shown that there’s an inverse correlation between government ownership in banks and a country’s GDP per capita and productivity growth.

Fourth, you have runs, panics, and scandals. Remember, trust is vital to the financial system. When trust erodes, depositors may rush to withdraw their money from banks, causing what is known as a “bank run.” This can cause banks to fail, as we saw during the Great Depression. Scandals can also depress market confidence. Enron, WorldCom and Bernie Madoff may come to mind.

So, which of these four factors contributed to the Great Recession of 2008?

We’ll discuss that in our next video.

In Intro to the Bond Market, you learned the basics about bonds and how they differ from stocks. But what if you’re investing and you’ve got a few possible companies to choose from? How would you evaluate which bond is likely to be the best investment for you?

Let’s look at an example from our bond market practice questions:

Suppose you’d like to invest in a company and you’ve narrowed your choice down to three firms: Company A is offering a zero-coupon bond with a face value of $1000 to be repaid in 1 year for $963. Company B has the same face value and maturity date but sells for $871. And company C also has the same face value and maturity but sells for $985. In which would you rather invest?

If some of the terms have you scratching your head, don’t worry! Go ahead and start this Office Hours video. Mary Clare Peate from the MRU team will cover the jargon and give you the tools you need to master the problem on your own.
