econlife - How a Sock Puppet Created a Bubble by Elaine Schwartz


Several years ago we asked why markets and bubbles always seem to find each other. Then we looked at tulip bulbs, Beanie Babies, and bowling. Today let’s add the Pets.com sock puppet and a 1920s Florida housing boom.

Where are we going? To what they all have in common.

The Pets.com Bubble

Let’s start with a sock puppet who was the Pets.com “spokesdog.”





In 1998, an online pet store was a new idea. But they got millions in venture capital funding (even from Amazon) and called themselves Pets.com. With their cute and clever sock puppet, Super Bowl ads, and a Macy’s Thanksgiving Day Parade float, they created buzz and spent a lot of money. Its former CEO explains that it was tough to do internet business then. Imagine no plug and play and no cloud computing. You needed to do it all yourself. Then, to attract customers and offset high shipping costs, they had to discount below cost.

The firm went public in February 2000. By November it was in “doggy heaven.” Through their initial public offering (selling stock to you and me) and venture capital they raised hundreds of millions of dollars. At the end the stock was selling for 22 cents, down from its IPO high of $11.

At the same time, other e-tailers were experiencing a similar demise. Few of us remember MotherNature.com, Garden.com, Drkoop.com. You can see the downdraft after the March 3, 2000 high. Dominated by sick tech, the Nasdaq composite more than halved:





A Florida Bubble

Like selling pet supplies online, a Florida vacation was once a new idea. Before 1920, Miami Beach, Coral Gables and Tampa—indeed, most of the Florida we know today—did not even exist. But then the auto created unheard of mobility and a swarm of developers transformed one huge expanse of swampland into a vacation wonderland … or what was supposed to become one.

In 1925, two thousand Miami real estate agents were reputedly selling acreage. Entire communities were planned and sold long before the first bulldozers appeared. Across the state people were moving tons of sand, paving streets, and building houses and hotels. Without even counting vacationers, Miami’s population jumped from 30,000 in 1920 to 75,000 five years later.

The rise and fall took close to five years.

The Florida boom collapsed in 1926. At first people began to default on payments for land on which they had left a binder. It was said that one gentleman who had sold some property for $12 an acre experienced regret because the land was resold repeatedly, at first for $17, then $30, and finally $60 an acre. The gentleman had cause for further regret. Because no one in the sequence of transactions had paid what was due, once Florida’s economic decline began, the property moved backward from hand to hand. The story ends with him repossessing his land.

Compounding the economic contraction in Florida were the other calamities that followed. Two hurricanes struck. A September 18, 1926, storm targeted Miami. It left hundreds dead and roofs, autos, yachts, and other assorted debris strewn haphazardly in its wake. The next step was for the banks to fail. With everyone needing more money and few having it, the number of Florida’s bank collapses steadily climbed. From 31 in 1928 to 57 in 1929, the number was destined to rise even further. The final blow was struck when the Mediterranean fruit fly destroyed the 1929 citrus crop. Because of the nationwide decline, there was no one to pick up the pieces in Florida.

Our Bottom Line: Speculative Manias

Like Pets.com and Florida real estate, all bubbles start with something new that captivates the market. As euphoria builds, so too do demand driven price increases. Then, with speculative purchases escalating, prices move even higher. But always, the euphoria switches to panic, sellers multiply, and the market crashes. On the way up, participants like to say “This time it’s different.” They have relatively easy access to money. They enjoy irrational exuberance and believe puffed up growth stories. Inject all of that with a dose of moral hazard that obscures your risk and you get your bubble.

My sources and more: This WSJ quiz and this week’s stock market plunge started me thinking about market manias. WSJ was also ideal for the Pets.com story. As for Florida, I’ve copied an excerpt from my Econ 101 1/2.

Several sentences from this post’s Bottom Line were in a previous econlife.

Genius Hour by Mike Siekkinen


My team did a Genius Hour program earlier this school year and it was both fun and educational for the students.

Genius Hour is an approach to learning built around student curiosity, self-directed learning, and passion-based work. In traditional learning, teachers map out academic standards, and plan units and lessons based around those standards. In Genius Hour, students are in control, choosing what they study, how they study it, and what they do, produce, or create as a result.

As a learning model, it promotes inquiry, research, creativity, and self-directed learning. Students spend time working on projects they’re interested in and passionate about. The study and work is motivated intrinsically, not extrinsically. Genius Hour provides students freedom to design their own learning during a set period of time during school. It allows students to explore their own curiosity. A distinction compared to more open, self-directed learning and user-generated learning experiences is that within a “Genius Hour” framework, this student-centered approach is only used a portion of the schedule, providing students a choice in what they learn and how they learn it during a set period of time within a school day.

We used an hour a day for a three week period as our time frame. Without teachers “packaging” content that frames and scaffold content, students are left to design their own learning experiences. Through surveying possibility, navigation of unfiltered content, gathering information, and narrowed research, students make sense of ideas that are important to them. This navigation and survey of possibility then leads to more narrow inquiry and research.

Whether students “make,” publish, design, act, or do, “creating” is core to Genius Hour. There is always a visible product or function of the learning as an end product. Students connect with teachers to plan, peers to produce, and experts and community members to establish a sense of purpose for their work. The only guidelines we gave students were the components of the project (a prototype, a written explanation and a presentation they needed to do presenting their ideas). The assignment was they had to make something that will help another person. The products students produced were excellent. The ideas they had and what they came up with were really outstanding. Along with this, students enjoyed the assignment making learning fun!

econlife - The Six Facts That We Need To Know About the Federal Reserve by Elaine Schwartz


Our story begins in lower Manhattan during October 1907.

Anxious depositors could be seen camping overnight as they waited for the banks to open. Stuck for hours, they got food from friends and numbers from the police to establish their place in line. Meanwhile bank tellers were told to count out the money very, very slowly.

A failed attempt to corner the shares of United Copper had started the problems. When the news spread, depositors rushed to withdraw their money from the Knickerbocker Trust because it had provided funding for the disastrous maneuver. Fearing the bank’s insolvency, they hastened it by trying to withdraw more than the bank could give them. Soon, the fear moved beyond Knickerbocker to more banks and to less industrial production.

A good solution did not exist. The Knickerbocker and other ailing financial institutions had no way to get a cash infusion from the banks that were healthy because there was no central authority that connected them. There was only J.P. Morgan. As a banking superpower, he gathered the resources that ended the panic.

The next part of our story takes place three years later.

At an elite and inaccessible club in Georgia, six leading financiers and bankers secretly met during November 1910. They were even told to arrive separately at a private train in NJ that took them to more than a week of non-stop work.

The club where they met:



Knowing panics could be controlled by a nationwide banking system, the Jekyll Island group sought to create one. Their goal was an elastic currency and a system of interest rates that could respond to financial crises. The result was a proposal that was passed by the Congress and signed by President Wilson during December 1913. It became the Federal Reserve System.

Six Facts About the Federal Reserve

1. The Federal Reserve is a central bank.

Its main job is to regulate the U.S. supply of money and credit. As an independent agency within the federal government, the Fed is protected from political influence. So yes, the President with the “advice and consent” of the Senate appoints the Chair of the Federal Reserve for a four-year term. Afterwards though, that Chair (with the other Fed officials) independently makes monetary policy decisions.

2. The Fed’s structure extends around the United States.

Although its home is in Washington D.C., the Fed is composed of 12 regional banks. Each one keeps an eye on its own location. In addition, the NY Fed plays a special role as the place that implements FOMC (Federal Open Market Committee) decisions. It’s the job of the FOMC to oversee the securities that the Fed buys and sells.

The Fed’s structure:




3. When it buys and sells securities, the Fed targets the interest rates that influence economic activity.

I tell my class “buy/boost” and “sell/sink.” By buying securities like Treasury bills from banks, businesses, and governments, the Fed tries to increase the money supply and lower interest rates. Oversimplifying, we can just say those purchases place money in the sellers’ bank accounts. Then the banks have more money and rates can drop. When the Fed sells securities to the private sector and governments, then the Fed gets the money and the banks have less.

4. Fed Policy has three basic goals.

The Federal Reserve is supposed to maintain low inflation, low unemployment, and healthy economic growth. If the Fed is concerned about unemployment and slow growth then it lowers interest rates. To end the Great Recession, the Fed resorted to Quantitative Easing through which it flooded the banks with money from purchased securities. However, when inflation is a threat and the price level could rise too much (2% or so has been a target), then the Fed needs its sell/sink policy tools. You can see that the two policy tools are contradictory. The former propels the economy while the latter constrains it.

5. Recent interest rate policy increases have been controversial.

A former head of the Fed said, “The Federal Reserve… is in the position of the chaperone who has ordered the punch bowl removed just when the party was really warming up.” Because this Fed role involves precautionary action that prevents excessive inflation, politicians, consumers, and businesses are rarely happy. They don’t like higher rates that could slow economic exuberance.

When rates started skyrocketing in 1980, they were supposed to attack 13.5% inflation. You can see below how the rhythm of rates parallels the onset and disappearance of recessions:




6. The Fed’s monetary policy matters.

The supply of money and credit and the nation’s production of goods and services relate to each other. It’s like Goldilocks. The country needs the right amount of money and credit for whatever it produces. When there is too much money and credit, we have inflation. Too little, and we wind up with a recession. Just right, and the economy functions smoothly.

Our Bottom Line: Government Economic Policy

Monetary policy is just one half of the picture. We also have the taxes, spending, and borrowing that the President and the Congress control.  Like monetary policy, taxes and spending can also affect inflation and employment.

My sources and more:  BusinessInsider had a good explanation that goes beyond the Fed basics I’ve presented. In addition, I recommend going to the Federal Reserve for some history and the St. Louis Fed for more about the punch bowl (our featured image).

econlife - How an Art Heist Is like the Government Shutdown by Elaine Schwartz


An art thief, the U.S. President, and Democratic party leaders could all share the same dilemma.

Let’s take a look.

The Art Heist

On May 20, 2010, a thief called Spiderman stole five paintings from a French museum. After removing a window and avoiding the alarms, he left with works done by Léger, Matisse, Modigliani, Braque, and Picasso. Their value? $70 million or so.

The stolen Léger was “Still Life With Candlestick”:





The thief’s voicemail even said, “If you want to buy paintings or works of art, or exceptional jewelry, do not hesitate to contact me. Among the many paintings, there are five that are extremely expensive.” So yes, months later the police arrested the man who did the heist and the two men who were trying to sell the paintings for him. While one confessed and the others did not, all were convicted. Now serving sentences from 6 to 8 years, they won’t say where to find the stolen loot.

And this is where economic theory enters the picture.

If they all know where the paintings are hidden, it’s to their advantage to act together when they leave prison. However, one cannot be sure what the others will do. If one of the three acts in his own interest first then the others will suffer. But if they wait, they could all benefit. Assuming they cannot coordinate a strategy in jail, each has to decide which course of action is optimal. Each needs to understand game theory.

The Shutdown

December 22, 2018 was the first day that the U.S. government partially shut down. For it to open, politicians need to negotiate an agreement on issues that relate to border security and immigration. Like the art felons, they are figuring out a balance between cooperation and competition.

The length of shutdown negotiations:




Also like the felons, their individual goals differ. Consequently, each has to decide how much to sacrifice for a mutually sought outcome.

Our Bottom Line: Game Theory

Sometimes you have to know what your opponent will do in order to decide how to act. The problem though is that it’s all a prediction. You have to figure out your response before you know what to respond to. What you do can be explained by game theory.

Prison

A classic example of game theory is called the prisoner’s dilemma. When two partners in crime are arrested, one knows that if he confesses and his partner does not, then he will go free. But if both keep quiet, they both go to jail for one year. Because they are questioned separately, no one knows what the other has said. But the results depend on how much the other person admitted.

The dilemma: Keep quiet or confess?


Called the economics of cooperation (or non-cooperation), game theory explains the prisoners’ alternatives. When big businesses compete, game theory provides insight about their pricing strategy. In a soccer game, we can use game theory to understand shootouts.

And, when President Trump, Speaker Pelosi, and Minority Leader Schumer negotiate the end of the shutdown, each one’s strategy relates to game theory.

My sources and more: In an excellent piece, The New Yorker told about the Paris art heist. Meanwhile, in 2014, Quartz focused on soccer shootout game theory and The Economist had a good discussion of how game theory works. But if you just read one article, do look at this John Nash obituary.

Please note that sections of today’s Bottom Line were in a previous econlife post.

econlife - Top Ten Ways to Sound Like an Economist by Elaine Schwartz


If one of your New Year’s resolutions is to sound like an economist, please remember the following…and do send in your own suggestions.

Top Ten New Year’s Additions:

  • When you are at an AMC theater deciding among the 100+ selections in the Coke machine, you might worry about choice fatigue
  • Explaining the financial hardship experienced by a furloughed government worker during the shutdown, you can refer to negative externalities.
  • When asked why we have done nothing about Medicare’s trust fund running out in 2026, you can reply that Congress’s opportunity cost is too high.
  • Knowing that the Dow dropped 6% during the second year (2018) of the Trump presidency–its worst decline in a decade– you can ask if it was correlation or causation.


The Original Top Ten List

  1. Whatever the question, always answer, “There’s no such thing as a free lunch.”
  2. Defend a decision by declaring, “It was worth the opportunity cost.”
  3. Whether you like or dislike government, point to, “The power of the market.”
  4. Explain a love of low prices with, “It’s the law of demand.
  5. Explain high prices with, “It’s the law of supply.
  6. Preface a position with, “on the one hand…but on the other…”
  7. Justify your Thai T-shirt, Japanese camera, and Sumatran coffee beans by repeating, comparative advantage, comparative advantage…”
  8. When asked, “How are we doing?” just cite the GDP, CPI, and S&P.
  9. Know that the size of the pie has nothing to do with food.
  10.  And finally, the most dependable way to “think economically” is to remember that, no matter what the topic, “It’s about the economy…”

Here is one I got from Kevin Denny (Thank you!):

  • To reject any inconvenient fact, “The econometric evidence is not clear on this.”

 Enjoy and Happy New Year!

econlife - Six Facts About How Supermarkets Influence What We Buy by Elaine Schwartz


Like me, have you ever raced into your local market to get some milk and passed through produce and other aisles, grabbing some items you never realized you needed? One supermarket executive called it “building the basket” when they lure us to the rear of the store. (It is also true that if they didn’t move the milk from the truck to a back cooler, they would diminish refrigeration time and increase labor expense.)

But still, the store did nudge me to spend more money.

Six Facts About How Supermarkets Influence Us

1. Supermarket bars and restaurants affect our spending.

Yes, supermarkets are adding bars. Called a “superbarket” in Vox, grocery stores are inviting us to drink while we shop. For them, it’s a win-win. Groceries are low margin purchases but not booze. And after a drink or two, maybe, as we careen through the grocery aisle, we buy more. Whole Foods started it all in 2009. Then others copied. Similarly, Eater said we now have the “grocerant” where we can eat dinner too.

2. Music can impact how much we spend.

In one classic 1982 study, researchers observed the response to no music, slow tempo music, and fast tempo music. Keeping track of pace also, they hypothesized that the slower movements that responded to calmer music were accompanied by more shopping.

Taking the next step at a wine store, psychologists looked at whether the type of music made a difference. Discovering it did, they found that French music was correlated with French wine sales, And yes, German music increased the German wine purchases.

3. The size of our supermarket cart affects our purchases

Carts have gotten bigger. The supermarket cart was first invented (1937) by a retailer who wanted us to buy more than we could carry. More recently, stores have larger aisles, women working away from home who can visit the market less frequently, and stores like Costco that encourage bulk purchases. Whatever the reasons, journalists say that carts have tripled in size from 1975 to 2000. Others claim that Whole Foods doubled cart size between 2009 and 2011. However, the one statistic that seems most reliable indicates that when a researcher doubled cart size, customers bought 19% more.

4. Shelf layout influences our decisions.

Supermarkets have to decide who can occupy their prime “property.” Like beachfront homes, the supermarket checkout area is a coveted location. For the same reason, a separate display at the end of an aisle is a desirable spot. And, in a typical cooler, we would mostly see products from large multinationals. For example, Dreyer’s, Skinny Cow, Edy’s and Häagen-Daz are actually all Nestlé. Similarly Magnum, Ben & Jerry’s, Breyer’s, Klondike and Talenti are from Unilever. If the aisle had 24 doors, only two might lead to the generics and niche brands.

5. Product descriptions affect what we think we should buy.

At Trader Joe’s, a smaller U.S. grocery chain (owned by Germany-based Aldi), they care about their adjectives. Catering to a niche market of shoppers who want bargains and healthy food, they mostly name and sell their own brands. The label on some nuts could say Sea-salt-and-turbinado sugar-chocolate almonds while a chicken dish is spatchcocked lemon-rosemary chicken. That turbinado just refers to a certain type of sugar cane. But it sounds good.

6. Finally, it’s the choice dilemma.

Some stores like Trader Joe’s believe less is more. Typically they have only 3,000 or so SKUs–stock-keeping units–the number of items in a store. A normal supermarket has more than 35,000 SKUs.

According to Columbia professor Sheena Iyengar, less of a choice generates higher sales. However, the bigger chains give us much more.

Our Bottom Line: Nudges

Nobel Laureate Richard Thaler and his co-author Cass Sunstein tell us that we go through life influenced by nudges that shape our behavior. A behavioral economist calls the phenomenon choice architecture. Indeed, through sound, transport, language, choice, and placement, the “architecture” of the supermarket affects how much money we spend.

My sources and more: If you just listen to one podcast about supermarket behavior, I recommend this Freakonomics episode on Trader Joe’s. However, to read onward, you can look at Consumerist for cart size, this classic study for music, and Businessinsider for the wine study. Then Vox and Eater told me about grocery store bars and restaurants while NPR explained why the milk is in the back of the store.

Teaching with Videos by Mike Siekkinen


As a history teacher, I regularly use video when teaching. I would love to be able to take my students to the places we study, to actually see and experience where history took place, but that is not really an option in most cases. Video can be the next best thing.

Some of my favorite sites are Discovery Channel and I also use GPB (Georgia Public Broadcasting) frequently. YouTube can also be a great source for content, not just in history but all subjects.  And of course, I can’t forget izzit.org!

As with any video used in the classroom, I always ensure I watch everything first. I learned this early on in my educational career when teaching biology. I found a great (I thought) frog dissection video on YouTube. On the surface, it was excellent, going over each step of the dissection process with the students doing the narration. That was, until several of the students started using cuss words. In hindsight, I am so glad I watched this video in its entirety as this could have been very embarrassing otherwise.

Hollywood has done a great job in a number of circumstances with historical period pieces. As with any video, I always have things for students to do as they are watching. Additionally, for videos of any length, I will often pause and we will discuss points I want to bring up, and/or have students respond to prompts I give them during parts of the video.

Please do look at your school systems policy regarding video use in the classroom. Some districts have very strict policies about video use, while others leave everything up to the discretion of the teacher.

izzit.org has great videos that can be streamed directly by students. This year, I started assigning students videos to watch and then having them take the online quizzes. Students can do these at their own pace from individual Chromebooks. These would be supplemental to instruction. Give them a try.
