What is Gross Domestic Product (GDP)?
 
04:36
Picture the economy as a giant supermarket, with billions of goods and services inside. At the checkout line, you watch as the cashier rings up the price for each finished good or service sold. What have you just observed? The cashier is computing a very important number: gross domestic product, or GDP. GDP is the market value of all finished goods and services, produced within a country in a year. But, what does "market value" mean? And what defines a "finished good"? These, and more questions, percolate inside your head. Meanwhile, the cashier starts ringing up the total, and you’re left confused. An array of things pass by you — A bottle of wine. A carton of eggs. A cake from the local bakers. A tractor, of all things. A bunch of ballpens. A bag of flour. In this video, join us as we show you how to make sense of this important economic indicator. You’ll learn how GDP is computed, and you’ll get answers to some pretty interesting questions along the way. Questions like, “Why are the eggs in my homemade omelet part of the GDP, but the eggs my baker uses are not? Why does my bottle of French wine contribute to France’s GDP, even if I bought it in the United States?” Most importantly, you’ll also learn why polar bears aren’t part of the GDP computation, even if they’re incredibly cute. So, buckle in for a bit—in the following videos we’ll dive into specifics on GDP.

Zimbabwe and Hyperinflation: Who Wants to Be a Trillionaire?
 
04:20
How would you like to pay $417.00 per sheet of toilet paper? Sound crazy? It’s not as crazy as you may think. Here’s a story of how this happened in Zimbabwe. Around 2000, Robert Mugabe, the President of Zimbabwe, was in need of cash to bribe his enemies and reward his allies. He had to be clever in his approach, given that Zimbabwe’s economy was doing lousy and his people were starving. Sow what did he do? He tapped the country’s printing presses and printed more money. Clever, right? Not so fast. The increase in money supply didn’t equate to an increase in productivity in the Zimbabwean economy, and there was little new investment to create new goods. So, in effect, you had more money chasing the same goods. In other words, you needed more dollars to buy the same stuff as before. Prices began to rise -- drastically. As prices rose, the government printed more money to buy the same goods as before. And the cycle continued. In fact, it got so out of hand that by 2006, prices were rising by over 1,000% per year! Zimbabweans became millionaires, but a million dollars may have only been enough to buy you one chicken during the hyperinflation crisis. It all came crashing down in 2008 when -- given that the Zimbabwean dollar basically ceased to exist -- Mugabe was forced to legalize transactions in foreign currencies. Hyperinflation isn’t unique to Zimbabwe. It has occurred in other countries such as Yugoslavia, China, and Germany throughout history. In future videos, we’ll take a closer look at inflation and what causes it.

Indifference Curves
 
08:28
Think about what restricts your choices when it comes to buying goods and services. Your income is one variable. Prices are another. What about what you like and don’t like? That’s an important one! Your preferences play a huge role in how you decide to spend your money. We often face so many options when it comes to what we buy that it can be difficult to decide. Even with a simple example of pizzas and coffees, there can be many combinations that would give you the same level of satisfaction or happiness – what economists call utility. There are also many combinations to which you might find yourself totally indifferent. In this video, Arizona State University’s Professor Joana Girante will show you how to graph an indifference curve. She’ll also introduce you to marginal rates of substitution (don’t worry, it sounds more complicated than it is!). We’ll also take a look at how perfect substitutes and perfect complements change the shape of an indifference curve.

Quantity Theory of Money
 
03:28
The quantity theory of money is an important tool for thinking about issues in macroeconomics. The equation for the quantity theory of money is: M x V = P x Y What do the variables represent? M is fairly straightforward – it’s the money supply in an economy. A typical dollar bill can go on a long journey during the course of a single year. It can be spent in exchange for goods and services numerous times. In the quantity theory of money, how many times an average dollar is exchanged is its velocity, or V. The price level of goods and services in an economy is represented by P. Finally, Y is all of the finished goods and services sold in an economy – aka real GDP. When you multiply P x Y, the result is nominal GDP. Actually, when you multiply M x V (the money supply times the velocity of money), you also get nominal GDP. M x V is equal to P x Y by definition – it’s an identity equation. You can think about the two sides of the equation like this: the left (M x V) covers the actions of consumers while the right (P x Y) covers the actions of producers. Since everything that is sold is bought by someone, these two sides will remain equal. Up next, we’ll use the quantity theory of money to discuss the causes of inflation.

Asymmetric Information and Used Cars
 
02:40
George Akerlof, a Nobel Prize-winning economist, analyzed the theory of adverse selection – which occurs when an offer conveys negative information about what is being offered. In the market for used cars, Akerlof posited that sellers have more information about the car’s quality than buyers. He argued that this leads to the death spiral of the market, and market failure. However, the market has developed solutions such as warrantees, guarantees, branding, and inspections to offset information asymmetry.

Intro to the Solow Model of Economic Growth
 
05:17
Here's a quick growth conundrum, to get you thinking. Consider two countries at the close of World War II—Germany and Japan. At that point, they've both suffered heavy population losses. Both countries have had their infrastructure devastated. So logically, the losing countries should’ve been in a post-war economic quagmire. So why wasn't that the case at all? Following WWII, Germany and Japan were growing twice, sometimes three times, the rate of the winning countries, such as the United States. Similarly, think of this quandary: in past videos, we explained to you that one of the keys to economic growth is a country's institutions. With that in mind, think of China's growth rate. China’s been growing at a breakneck pace—reported at 7 to 10% per year. On the other hand, countries like the United States, Canada, and France have been growing at about 2% per year. Aside from their advantages in physical and human capital, there's no question that the institutions in these countries are better than those in China. So, just as we said about Germany and Japan—why the growth? To answer that, we turn to today's video on the Solow model of economic growth. The Solow model was named after Robert Solow, the 1987 winner of the Nobel Prize in Economics. Among other things, the Solow model helps us understand the nuances and dynamics of growth. The model also lets us distinguish between two types of growth: catching up growth and cutting edge growth. As you'll soon see, a country can grow much faster when it's catching up, as opposed to when it's already growing at the cutting edge. That said, this video will allow you to see a simplified version of the model. It'll describe growth as a function of a few specific variables: labor, education, physical capital, and ideas. So watch this new installment, get your feet wet with the Solow model, and next time, we'll drill down into one of its variables: physical capital.

Comparative Advantage
 
07:15
What is comparative advantage? And why is it important to trade? This video guides us through a specific example surrounding Tasmania — an island off the coast of Australia that experienced the miracle of growth in reverse. Through this example we show what can happen when a civilization is deprived of trade, and show why trade is essential to economic growth. In an economy with a greater number of participants trading goods and services, there are more ways to find a comparative advantage and earn more by creating the most value for others. Let’s dive right in with an example from our new friends, Bob and Ann.

The Equilibrium Price and Quantity
 
04:51
In this lesson, we investigate how prices reach equilibrium and how the market works like an invisible hand coordinating economic activity. At equilibrium, the price is stable and gains from trade are maximized. When the price is not at equilibrium, a shortage or a surplus occurs. The equilibrium price is the result of competition amongst buyers and sellers.

The Hockey Stick of Human Prosperity
 
04:55
In this series, Professor Don Boudreaux explores the question economists have been asking since the era of Adam Smith -- what creates wealth? On a timeline of human history, the recent rise in standards of living resembles a hockey stick -- flatlining for all of human history and then skyrocketing in just the last few centuries. Without specialization and trade, our ancient ancestors only consumed what they could make themselves. How can specialization and trade help explain the astonishing growth of productivity and output in such a short amount of time—after millennia of famine, low life expectancy, and incurable disease? What topic should we do next? http://bit.ly/1QWdvOn Ask a question about the video: http://bit.ly/21HwvW1 Next video: http://bit.ly/1Qum40J Help us caption & translate this video! http://amara.org/v/Elbp/
Trading Pollution: How Pollution Permits Paradoxically Reduce Emissions
 
04:09
In an effort to reduce pollution, the government tried two policy prescriptions under the Clean Air Act Amendments of 1990. The first—command and control—mandated that each power plant lower its pollution by a determined amount. However, different firms face different cost curves and, because information is dispersed, policymakers don’t always know those costs. The second policy prescription—tradable pollution permits—empowered firms to use knowledge of their cost curves to buy or sell pollution permits as needed. Under this policy, the invisible hand of the market helped discover the lowest cost way of reducing pollution.  Microeconomics Course: http://bit.ly/20VablY Ask a question about the video: http://bit.ly/1p5hfkn Next video: http://bit.ly/1R24Bch Help us caption & translate this video! http://amara.org/v/GSnT/
Nominal vs. Real GDP
 
07:41
"Are you better off today than you were 4 years ago? What about 40 years ago?" These sorts of questions invite a different kind of query: what exactly do we mean, when we say “better off?” And more importantly, how do we know if we’re better off or not? To those questions, there’s one figure that can shed at least a partial light: real GDP. In the previous video, you learned about how to compute GDP. But what you learned to compute was a very particular kind: the nominal GDP, which isn’t adjusted for inflation, and doesn’t account for increases in the population. A lack of these controls produces a kind of mirage. For example, compare the US nominal GDP in 1950. It was roughly $320 billion. Pretty good, right? Now compare that with 2015’s nominal GDP: over $17 trillion. That’s 55 times bigger than in 1950! But wait. Prices have also increased since 1950. A loaf of bread, which used to cost a dime, now costs a couple dollars. Think back to how GDP is computed. Do you see how price increases impact GDP? When prices go up, nominal GDP might go up, even if there hasn’t been any real growth in the production of goods and services. Not to mention, the US population has also increased since 1950. As we said before: without proper controls in place, even if you know how to compute for nominal GDP, all you get is a mirage. So, how do you calculate real GDP? That’s what you’ll learn today. In this video, we’ll walk you through the factors that go into the computation of real GDP. We’ll show you how to distinguish between nominal GDP, which can balloon via rising prices, and real GDP—a figure built on the production of either more goods and services, or more valuable kinds of them. This way, you’ll learn to distinguish between inflation-driven GDP, and improvement-driven GDP. Oh, and we’ll also show you a handy little tool named FRED — the Federal Reserve Economic Data website. FRED will help you study how real GDP has changed over the years. It’ll show you what it looks like during healthy times, and during recessions. FRED will help you answer the question, “If prices hadn’t changed, how much would GDP truly have increased?” FRED will also show you how to account for population, by helping you compute a key figure: real GDP per capita. Once you learn all this, not only will you see past the the nominal GDP-mirage, but you’ll also get an idea of how to answer our central question: "Are we better off than we were all those years ago?"

Intro to the Bond Market
 
06:24
Most borrowers borrow through banks. But established and reputable institutions can also borrow from a different intermediary: the bond market. That’s the topic of this video. We’ll discuss what a bond is, what it does, how it’s rated, and what those ratings ultimately mean. First, though: what’s a bond? It’s essentially an IOU. A bond details who owes what, and when debt repayment will be made. Unlike stocks, bond ownership doesn’t mean owning part of a firm. It simply means being owed a specific sum, which will be paid back at a promised time. Some bonds also entitle holders to “coupon payments,” which are regular installments paid out on a schedule. Now—what does a bond do? Like stocks, bonds help raise money. Companies and governments issue bonds to finance new ventures. The ROI from these ventures, can then be used to repay bond holders. Speaking of repayments, borrowing through the bond market may mean better terms than borrowing from banks. This is especially the case for highly-rated bonds. But what determines a bond’s rating? Bond ratings are issued by agencies like Standard and Poor’s. A rating reflects the default risk of the institution issuing a bond. “Default risk” is the risk that a bond issuer may be unable to make payments when they come due. The higher the issuer’s default risk, the lower the rating of a bond. A lower rating means lenders will demand higher interest before providing money. For lenders, higher ratings mean a safer investment. And for borrowers (the bond issuers), a higher rating means paying a lower interest on debt. That said, there are other nuances to the bond market—things like the “crowding out” effect, as well as the effect of collateral on a bond’s interest rate. These are things we’ll leave you to discover in the video. Happy learning!

The Solow Model and the Steady State
 
07:10
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.

Adam Smith, Theory of Moral Sentiments
 
08:22
Adam Smith's Theory of Moral Sentiments (1759) lays out his moral philosophy, and provides the philosophical and psychological underpinnings of the better-known Inquiry Into the Nature and Causes of the Wealth of Nations (1776). In this video, prepared for the History of Economic Thought course for economics majors at Northwestern University, I highlight the main ideas in Theory of Moral Sentiments and their relevance to Smith's subsequent works.

Basic Facts of Wealth
 
04:28
We know that there are rich countries, poor countries, and countries somewhere in between. Economically speaking, Japan isn’t Denmark. Denmark isn’t Madagascar, and Madagascar isn’t Argentina. These countries are all different. But how different are they? That question is answered through real GDP per capita—a country’s gross domestic product, divided by its population. In previous videos, we used real GDP per capita as a quick measure for a country’s standard of living. But real GDP per capita also measures an average citizen’s command over goods and services. It can be a handy benchmark for how much an average person can buy in a year -- that is, his or her purchasing power. And across different countries, purchasing power isn’t the same. Here comes that word again: it’s different. How different? That’s another question this video will answer. In this section of Marginal Revolution University’s course on Principles of Macroeconomics, you’ll find out just how staggering the economic differences are for three countries—the Central African Republic, Mexico, and the United States. You’ll see why variations in real GDP per capita can be 10 times, 50 times, or sometimes a hundred times as different between one country and another. You’ll also learn why the countries we traditionally lump together as rich, or poor, might sometimes be in leagues all their own. The whole point of this? We can learn a lot about a country’s wealth and standard of living by looking at real GDP per capita. But before we give too much away, check out this video -- the first in our section on The Wealth of Nations and Economic Growth.

Sticky Wages
 
04:40
Imagine you’re an employer during a recession, and you desperately need to cut labor costs to keep your firm afloat. Are you more likely to cut wages across the board for all employees, or institute layoffs for only some? While it may seem that wage cuts are the “better” choice, they aren’t as common as you might think. Why is that? To answer that question, this video explores a phenomenon known as “sticky wages.” In other words, wages have a tendency to get “stuck” and not adjust downwards. This occurs even during a recession, when falling wages would help end the recession more quickly. However, that’s not to say that wages cannot adjust downward for an individual during a recession. This can happen, but likely only after an employee has been fired from their initial job, and eventually rehired by a different firm at a lower wage rate. Back to our original question -- why are employers unlikely to cut wages? A big reason has to do with the effect on morale. Employees may become disgruntled and angry when they experience a nominal wage cut, and become less productive. An important note here -- notice that we said nominal wage cut, meaning, not adjusted for inflation. If an employee receives a 3% raise in nominal wages, they may remain happy in their current position. But what if inflation is 5%? What does this mean for their real wage? (Hint: For an in depth answer to this question check out our earlier Macroeconomics video on “money illusion.”) Next week we’ll return to our discussion on the AD/AS model for a look at how factors such as “sticky wages” affect the economy in the short run.

Elasticity and Slave Redemption

Why Governments Create Inflation
 
08:33
Inflation can carry with it quite a few costs. But some governments, like Zimbabwe under President Robert Mugabe in the early 2000s, will go out of their to way to create inflation. Why? Well, in the Zimbabwe example, the government printed the money and used it to buy goods and services. The ensuing hyperinflation acted as a tax that transferred wealth from the citizens to the government. However, this is a fairly uncommon reason. Inflation doesn’t make for a good tax and it’s a last resort for desperate governments that are otherwise unable to raise funds. There are other benefits to inflation that would make governments want to create it. In the short run, inflation can actually boost economic output. However, as we’ve previously covered, an increase in the money supply leads to an equal increase in prices in the long run. If there’s a recession, governments might create inflation to spur productivity and ease the economic downturn. However, this type of inflationary boosting can be abused. Long-term boosting causes people to simply expect and prepare for it. Reducing inflation is also costly. If the process is reversed and the growth in the money supply decreases, we get disinflation. Unemployment will likely increase in the short run and an economy can go through a recession. But in the long run, prices will adjust as well. Inflation can be a neat trick for governments to boost productivity in an economy. But it can easily get out of hand and has even been likened to a drug. Once you start, you need more and more. And stopping is awfully painful as the economy shrinks. This concludes our section on Inflation and the Quantity Theory of Money. Up next in Principles of Macroeconomics, we’ll be digging into Business Fluctuations.

Budget Constraints
 
06:46
Think through all of the variables that determine the price of a cup of coffee. It might help to imagine the coffee beans on the farm first. Consider the land costs and the price of the farmer’s labor. What about transportation of the beans to the roaster? There are packaging costs, oil costs, driver costs...and we’re still only talking about the beans! Once the roasted beans finally make it to your local coffee shop, they still have to be turned in that cup of coffee. The cost of rent for the building is a factor in the price of the final good, as is the labor of the barista and the price of electricity in your area. We’re barely scratching the surface here, but you get the idea that a ton of variables are behind the price of even a relatively simple good like a cup of coffee. What you, the consumer, are able and willing to pay is yet another one. Your salary helps set your budget constraints. And your budget constraints are a crucial variable in helping you decide whether to spend $5 on that cup of coffee, or $5 on something else. In this video, we’ll examine what budget constraints look like and how they function by graphing a simple example: $50 to spend on $5 coffees or $10 pizzas. You’ll see how the graph shifts as variables change. We’ll also use this example talk about a fundamental concept in economics that can help you make better decisions: opportunity costs.

Real GDP Per Capita and the Standard of Living
 
05:14
They say what matters most in life are the things money can’t buy. So far, we’ve been paying attention to a figure that’s intimately linked to the things money can buy. That figure is GDP, both nominal, and real. But before you write off GDP as strictly a measure of wealth, here’s something to think about. Increases in real GDP per capita also correlate to improvements in those things money can’t buy. Health. Happiness. Education. What this means is, as real GDP per capita rises, a country also tends to get related benefits. As the figure increases, people’s longevity tends to march upward along with it. Citizens tend to be better educated. Over time, growth in real GDP per capita also correlates to an increase in income for the country’s poorest citizens. But before you think of GDP per capita as a panacea for measuring human progress, here’s a caveat. GDP per capita, while useful, is not a perfect measure. For example: GDP per capita is roughly the same in Nigeria, Pakistan, and Honduras. As such, you might think the three countries have about the same standard of living. But, a much larger portion of Nigeria's population lives on less than $2/day than the other two countries. This isn’t a question of income, but of income distribution—a matter GDP per capita can’t fully address. In a way, real GDP per capita is like a thermometer reading—it gives a quick look at temperature, but it doesn’t tell us everything. It’s far from the end-all, be-all of measuring our state of well-being. Still, it’s worth understanding how GDP per capita correlates to many of the other things we care about: our health, our happiness, and our education. So join us in this video, as we work to understand how GDP per capita helps us measure a country’s standard of living. As we said: it's not a perfect measure, but it is a useful one.

The Money Multiplier
 
06:56
When you deposit money into a bank, do you know what happens to it? It doesn’t simply sit there. Banks are actually allowed to loan out up to 90% of their deposits. For every $10 that you deposit, only $1 is required to stay put. This practice is known as fractional reserve banking. Now, it’s fairly rare for a bank to only have 10% in reserves, and the number fluctuates. Since checkable deposits are part of the U.S. money supplies, fractional reserve banking, as you might have guessed, can have a big impact on these supplies. This is where the money multiplier comes into play. The money multiplier itself is straightforward: it equals 1 divided by the reserve ratio. If reserves are at 10%, the minimum amount required by the Fed, then the money multiplier is 10. So if a bank has $1 million in checkable deposits, it has $10 million to work with for stuff like loans and reserves. Now, typically, the money multiplier is more like 3, because banks can always hold more in reserves than the minimum 10%. When the money multiplier is higher, like during a boom, this gives the Fed more leverage to move M1 and M2 with a small change in reserves. But when the multiplier is lower, such as during a recession, the Fed has less leverage and must push harder to wield its indirect influence over M1 and M2. Next up, we’ll take a closer look at how the Fed controls the money supply and how that has changed since the Great Recession.

Introduction to Consumer Choice
 
04:42
Everyday, you make tons of decisions about consumption. Your choices about what and how much of a good to buy are influenced by the laws of supply and demand. These choices are nearly endless. For example, at Starbucks, each drink is highly customizable. In fact, they offer over 80,000 combinations! When you buy a good or make a decision about how to use your time, you’re getting some sort of value, like a sense of happiness or satisfaction, out of it – economists call this “utility.” The increase in that value from buying an additional unit of a good or service is its marginal utility. When you make these decisions, you’re thinking at the margin, even if you don’t realize it. Think about how wonderful a shot of espresso, or your beverage of choice, is first thing in the morning. You probably derive quite a bit of utility! But how about a second, third, or even fourth shot of espresso? With each extra shot, you probably get a little less utility. At some point, the cost will outweigh the marginal utility. When you add up the satisfaction you get out of all of the shots of espresso, that is your total utility. Since each additional shot of espresso has a little less utility, economists refer to this concept as diminishing marginal utility. This is true for all goods and activities, but the amount of utility and marginal utility depends on the individual. For example, let’s say that Starbucks drops the price of shot of espresso. This can change the quantity demanded on aggregate because for some people, the drop in price will make the marginal utility they derive from an extra shot now worth the cost. But perhaps that’s not true for you and your consumption will not change. Are you starting to see how you instinctively think and act at the margin in your daily life? Up next, we’ll explore other factors beyond price that affect your habits as a consumer, such as preferences and income.

What Is the Rule of 70?
 
03:29
What’s the “rule of 70?” The rule of 70 is an easy method of estimating how quickly a variable will double if you know its annual growth rate. If a variable is growing at a rate of x% per period, you simply take 70 and divide it by x. The rule of 70 is useful for all sorts of applications. For example, if you’ve saved some money in an investment account that’s growing at 5% per year, you can divide 70 by 5 to get an approximation for how quickly your savings will double. No complicated math required. But that’s not all! You can calculate how long it will take a country’s GDP to double, how quickly your startup’s users will double given its current growth rate, or when the number of bacteria in a petri dish will double. As you can see, there are many different applications of this rule! In the video, we’ll walk you through a few scenarios where using the rule 0f 70 lets you easily see the power of compounding without the trouble of actually doing the compounding math. (Bonus: You’ll also learn how to apply the rule of 70 in reverse.) MRU covers the rule of 70 in its video on "Growth Miracles and Growth Disasters" (http://bit.ly/2sWOMAj) in the Principles of Macroeconomics course. We also answer your questions on the rule of 70 in our Office Hours video on the topic (http://bit.ly/2shXHdZ).

Intro to Stock Markets
 
03:28
Today, we’ll examine a new kind of financial intermediary: stock markets. As an individual, you participate in the stock market when you buy a company’s shares. This turns you into a part-owner, entitled to some of the company's profits. Sometimes, profits are paid out directly via dividends. Other times, profits are reinvested for company growth. In this case, you benefit by seeing the value of your shares rise in tandem with this growth. Still, the buying and selling of stock doesn't actually create any new investment. Buying and selling only transfers ownership between stockholders. What actually creates investment is when a company offers stock to the public for the first time (known as an Initial Public Offering or IPO), which is when it issues new shares to raise money for key ventures. This process of turning savings into investment is what makes the stock market an intermediary. A key caveat, though—buying stock essentially means betting on a company. As with all gambles, sometimes it pays off, sometimes, it doesn't. For you as a saver, this means some of your stocks will win, and others, not so much. This volatility makes stock markets more risky than banks. Bank savers typically don't have to worry about fluctuations in the value of their deposits. As for the entrepreneurial side, the stock market is a key institution encouraging new businesses. For a founder, the payoff typically comes during the IPO. An IPO allows founders to sell some of their ownership (in a now more-valuable company) so they can diversify their own holdings. Next time, we'll look at the third kind of intermediary: bond markets.

Human Capital & Conditional Convergence
 
06:42
In our previous macroeconomics video, we said that the accumulation of physical capital only provides a temporary boost to economic growth. Does the same apply to human capital? To answer that, consider this: what happens to all new graduates, in the end? For a while, they’re productive members of the economy. Then age takes its toll, retirement rolls around, and eventually, the old workforce is replaced with a new infusion of people. But then, the cycle restarts. You get a new workforce, everyone’s productive for a while, and then they too retire. Does this ring a bell? It should, because this is similar to the depreciation faced by physical capital. Similarly, are there diminishing returns to education? It likely wouldn’t pay off for everyone to have a PhD, or for everyone to master Einstein’s great theories. That means the logic of diminishing returns, and the idea of a steady state, also applies to human capital. So, now we can revise our earlier statement. Now we can say that the accumulation of any kind of capital, only provides a temporary boost in economic growth. This is because all kinds of capital rust. So, one way or another, we’ll reach a point where new investments can only offset depreciation. It’s the steady state, all over again. However, what does the journey to steady state look like? The Solow model predicts that poor countries should eventually catch up to rich countries, especially since they’re growing from a lower base. And given their quicker accumulation of capital, poorer nations should also grow faster, than their more developed neighbors. And eventually, every country should reach similar steady states. In other words, we would see growth tracks that all eventually converge. So, why isn’t this always the case? Why, in some cases, are we seeing “Divergence, Big time,” as coined by economist Lant Pritchett? The answer to these questions, lies in the institutions of different countries and the incentives they create. Assuming that a certain set of countries do have similar institutions, that’s where we see the convergence predicted by the Solow model. We see that poorer countries do grow faster than their richer counterparts. And conditional on having similar institutions, eventually, even poorer countries will reach a similar steady state of output as more developed nations. We call this phenomenon conditional convergence. You can think of it as a national game of catch-up, with catch-up only happening if institutions don’t differ. What happens though, once all this catching up is done? Let’s not forget that there’s still another variable in the Solow model. This is variable A: ideas -- the subject of our next video. There, we’ll show you how ideas can keep a country moving along the cutting edge of growth.

Consumer Optimization
 
06:29
We live in a world of scarcity. In other words, what we want outweighs what we can attain. Why? Well, we have limited resources – money, options, time, etc. When you’re making choices about what to buy, your budget, the prices of goods and services, and your preferences all act as constraints. To better illustrate this idea, let’s return to our simple example of pizzas and coffees. Let’s also assume that you like both pizza and coffee and want more of both. If you were to look at a map of your indifference curves for these goods, you’d see that you get the most utility on the indifference curve farthest from the origin. But, since scarcity is our reality, that level of utility is probably not achievable. Combining your budget constraint with your indifference curves can help you see how to get maximum utility given your resources. Any point at which your budget constraint lies tangent to an indifference curve is an optimal combination of pizzas and coffees. Why is it optimal? Two simple reasons: 1) You can afford it, and 2) it will give you the most happiness (aka utility). In this video, Arizona State University’s Professor Joana Girante will further explain the concept consumer optimization and how it applies to your everyday life. She’ll also cover why your points of consumer optimization will never intersect, but always lie tangent to, your indifference curves. Finally. Prof. Girante will go over marginal rates of substitution in more detail.

Monetary Policy and the Federal Reserve
 
03:02
Spider-Man fans likely recall Uncle Ben advising his nephew, Peter Parker, that “With great power, comes great responsibility.” As it turns out, that sage wisdom is also pretty applicable to the U.S. Federal Reserve System (aka the Fed). The Fed Chairperson, currently Janet Yellen, may not shoot webs out of her wrists, but she and the organization she represents have some super powers over our money supply. The Fed also has quite a few limitations – monetary policy can only do so much. We’ve previously covered the quantity theory of money and long- and short-run economic growth. If you think back to those videos, you’ll remember that an increase in the money supply (which, in the U.S., is controlled by the Fed) only affects growth in the short-run. Even then, it’s often not smooth sailing. In this video, we’ll give you an introduction to the function of the Fed as well as some of the problems it faces, and raise the question, “What is money?” Subscribe for new videos every Tuesday! http://bit.ly/1Rib5V8 Macroeconomics Course: http://bit.ly/1R1PL5x Ask a question about the video: http://bit.ly/2tu13OM Next video: http://bit.ly/2t08M3A

Signaling
 
06:46
A signal is an action that reveals information. Let’s look at higher education, for example. A large fraction of the value you receive from your degree comes on the day you earn your diploma. Your expected wages don’t increase with each class you complete along the way; instead, they spike sharply at the end when you receive your diploma. This is often referred to as the “Sheepskin Effect” because diplomas used to be printed on sheepskin. Nobel Prize winner Michael Spence did research on this subject and found that education is valuable not necessarily because it creates valuable skills, but rather that it signals valuable skills. So how does the signal, represented by a degree, alleviate asymmetric information? Employers don’t necessarily know how smart or skilled you are. Your degree, however, provides a credible signal of these traits and gives them more information they can use in the hiring process. What other signals exist? We discuss examples like diamond engagement rings, why criminals tattoo their face, and why a peacock has a colorful tail. Let us know what examples you come up with in the comments.

Splitting GDP
 
06:00
In the last three videos, you learned the basics of GDP: how to compute it, and how to account for inflation and population increases. You also learned how real GDP per capita is useful as a quick measure for standard of living. This time round, we’ll get into specifics on how GDP is analyzed and used to study a country’s economy. You’ll learn two approaches for analysis: national spending and factor income. You’ll see GDP from both sides of the ledger: the spending and the receiving side. With the national spending approach, you’ll see how gross domestic product is split into three categories: consumption goods bought by the public, investment goods bought by the public, and government purchases. You’ll also learn how to avoid double counting in GDP calculation, by understanding how government purchases differ from government spending, in terms of GDP. After that, you’ll learn the other approach for GDP splitting: factor income. Here, you’ll view GDP as the total sum of employee compensation, rents, interest, and profit. You’ll understand how GDP looks from the other side—from the receiving end of the ledger, instead of the spending end. Finally, you’ll pay a visit to FRED (the Federal Reserve Economic Data website) again. FRED will help you understand how GDP and GDI (the name for GDP when you use the factor income approach) are used by economists in times of economic downturn. So, buckle in again. It’s time to hit the last stop on our GDP journey.

Growth Miracles and Growth Disasters
 
04:26
In previous videos, you learned two things. First, that there can be large disparities in economic wealth among different countries. And second, you learned that one key factor drives that disparity: growth rate. As we said, it changes everything. But just how transformative is a country's growth rate? Take Argentina, for example. In 1950, the Argentine standard of living was similar to that of many Western European countries. Up until 1965, Argentina's per capita income was ahead of many of its neighbors. On the other hand, Japan in 1950 was on the other end of the spectrum. Japan had been ravaged by war and was only just beginning to find its economic footing again. At that time, Japan's standard of living was roughly the same as that of Mexico. It was quite poor, compared to the Argentina of the same era. But look at what's happened in the past 65 years. Japan today is one of the world's most prosperous countries. Since 1950, it has managed to double its living standards about every eight years. Argentina, on the other hand, has stagnated. Once, Argentina had double the standard of living of Japan. But Japan now doubles them today, with a standard of living 10 times higher than the one it had in 1950. In economic terms, Japan is what we would call a growth miracle. It's in the same class as other growth success stories, like South Korea and China which have experienced the “hockey stick” of prosperity. (India seems like it may have started on this path as well.) These countries are proof of one thing: with the right factors, a poor country can not only grow, but it can do so quickly. It can catch up with developed countries at an astonishing rate. What took the United States two centuries of steady growth can now be achieved by other countries in about one-fifth the time. Catch-up can happen in 40 years—about the span of a generation or two. That's the good news. The bad news is, while growth can skyrocket in some countries, growth isn’t guaranteed at all. Argentina is an example of this. It grew well for a time, and then it stalled. Even worse than Argentina, are countries like Niger, and Chad, which are the very worst of growth disasters. Not only are these countries in extreme poverty, but they also have little to no growth. More than that, these countries have never experienced substantial growth in the past. But why does that all matter? It matters because growth isn't just about numbers. It's not just about more goods and services. When a country grows, its citizens often end up with longer, healthier, and happier lives. Conversely, the countries that are growth disasters have citizens in poverty, with shorter and less happier lives. As bleak as this seems, it’s the plain truth: while growth miracles are possible, growth disasters are, too. Which leaves us with another question: what causes either state? What leads to growth, prosperity, health, and happiness? And then, what leads to the opposite situation? We're excited to share the answer, but that's a topic for future videos. For now, check out this video to get up to speed on growth miracles and growth disasters.

Econ Duel: Will Machines Take Our Jobs?
 
09:56
Technological innovation has long triggered fears of mass unemployment. In fact, we’ve been worried about machines coming to take our jobs for over two centuries. Time and time again, these fears have proven unfounded. Automation frees up those resources that are uniquely human and new types of jobs end up being created. But new types of machines are also on the rise. They’re getting more capable of mimicking human intelligence, so we’re no longer only competing on physical labor. It’s a game changer. What does that mean for employment? Alex Tabarrok argues that the gains we’ve amassed from technological advances, including new varieties of jobs, will continue to outpace any negative effects on employment. On the other side of the ring, Tyler Cowen argues that machine intelligence makes today very different from previous periods in history and that there is cause for concern. He says we’re in for an adjustment and need to be prepared to adapt. There’s no doubt about it. Machines will continue to have a profound affect on how we work and the kinds of work we do. The details are up in the air, but economics can give us clearer insight into what we’re in for. So what do you think? Let us know whose side you’re on in the comments below!

Econ Duel: Fiat Money vs. the Gold Standard
 
09:59
Throughout the 19th century and up until the Great Depression, the gold standard was used in the United States. It was largely abandoned in the 20th century. But what is the gold standard? It’s a system for defining the value of a currency in terms of gold. In other words, you could exchange your $20 paper bill for actual gold at one point in history. Under a fiat money system, such as the one we have in the U.S. today, that $20 paper bill is inconvertible. You can’t exchange it for a backing store of value because there isn’t one. In this Econ Duel, economists Scott Sumner and Larry White, who both focus on monetary theory and policy, debate the positives and drawbacks to the gold standard vs. fiat money, and the role of central banks. On the side of the gold standard, White argues that, when properly implemented without a central bank intervening, it provides a more predictable price level and lower average inflation. Sumner, taking up the banner for fiat money, argues that the gold standard is simply a rule that worked well in the 19th century and that a good fiat money system is, for this day and age, a better alternative. Who won this Duel? Do you feel like you walked away with a better sense of the complexities of monetary policy? We’d love to hear from you!

The Aggregate Demand Curve
 
05:48
This wk: Put your quantity theory of money knowledge to use in understanding the aggregate demand curve. Next wk: Use your knowledge of the AD curve to dig into the long-run aggregate supply curve. The aggregate demand-aggregate supply model, or AD-AS model, can help us understand business fluctuations. In this video, we’ll focus on the aggregate demand curve. The aggregate demand curve shows us all of the possible combinations of inflation and real growth that are consistent with a specified rate of spending growth. The dynamic quantity theory of money (M + v = P + Y), which we covered in a previous video, can help us understand this concept. We’ll walk you through an example by plotting inflation on the y-axis and real growth on the x-axis -- helping us draw an aggregate demand curve!
