   Warm-Up Prompt

   "Think of one thing you use every week that did not exist when your grandparents were your age. Who do you think made it, and why did they take the trouble?"

   List answers on the board (phones, apps, streaming, electric scooters, a new cereal). Students usually say someone "invented" it to "make money" or "help people." Push one step further: an idea is not enough. Somebody had to build it, pay for it before anyone bought it, and convince people to buy it. Tell students that today's two key words are innovation and entrepreneurship, and that D2.Eco.7.6-8 asks them to analyze the role of both in a market economy.

   Invention	A new device or idea	A drawing and a working model of a new kind of lock
   Innovation	An invention or new method that is actually put to use and spreads	Many homes start using the new lock
   Product innovation	A new or better good or service	A backpack with a built-in phone charger
   Process innovation	A new or better way to make, sell or deliver something	A sandwich shop starts taking orders by text so lines move faster
   Entrepreneur	A person who starts a business, gathers the money, tools and workers it needs, and takes the risk	A cook who opens a food stand with her savings
   Profit	Money from sales minus all the costs of the business	$500 in sales minus $350 in costs is $150 of profit
   Risk	The chance of losing money, time or effort	The food stand may close if too few people buy
   Patent	A right granted by the government that lets only the inventor make and sell an invention for a limited time	Most U.S. patents today last 20 years from the date the inventor applies

   Part 1: Why innovation matters in a market economy. In a market economy no government office decides which new products to make. Inventors and businesses try ideas, and buyers decide which ones succeed by spending their money. An innovation can help in two ways: it can give buyers something new or better (a product innovation), or it can lower the cost of making something (a process innovation), which lets sellers charge less or earn more. The U.S. Constitution gives Congress the power "To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries." That is the basis of patents: a reward for inventing, for a limited time, after which anyone may copy the idea.

   Part 2: What entrepreneurs do. Entrepreneurs spot a want that is not being met, gather resources (money, tools, workers, space) and organize them into a business. They usually spend money before they earn any, so they take a risk. The reward they hope for is profit. The break-even point is the number of items a business must sell before its sales cover all its costs. Work these examples with the class.

   • Invention or innovation? (invented)

     Ana patents a folding wagon that fits in a school locker, but no store agrees to sell it and she sells only a handful online. Ben designs a rack that stacks cafeteria trays so they dry faster, and within two years 300 school cafeterias have bought it. Which is an invention only, and which has become an innovation?

     Result: Ana's wagon is an invention only: it works, but buyers have not put it to use. Ben's rack has become an innovation because buyers adopted it and it spread. It is a process innovation for the cafeterias, because it changes how they do their work. In a market economy, buyers decide which inventions become innovations.

   • An entrepreneur's break-even point and profit (invented; Diagram 2)

     Leo, 15, spends $1,200 on a used 3D printer to make phone stands. Plastic and electricity cost $2 for each stand, and he sells each for $8. How many stands must he sell to break even? What is his profit if he sells 260?

     Result: Each stand adds $8 - $2 = $6 toward his starting cost. Break-even: $1,200 / $6 = 200 stands. Profit at 260 stands: 260 x $6 - $1,200 = $1,560 - $1,200 = $360. If he sells only 150, he loses 150 x $6 - $1,200 = -$300, which shows his risk.

   • A process innovation lowers cost (invented)

     A bakery pays a worker $30 an hour. With its old oven, the worker makes 80 loaves an hour. A new oven lets the same worker make 120 loaves an hour. What happens to the labor cost of each loaf?

     Result: Old: $30 / 80 = $0.375, about 38 cents a loaf. New: $30 / 120 = $0.25, or 25 cents a loaf. The bread is the same product, so this is a process innovation. If rival bakeries compete for customers, some of the savings is likely to show up as lower prices.

   • Who gains and who loses when an innovation spreads? (qualitative)

     Streaming services let people watch movies at home without visiting a rental store. Over time, most video rental stores in the United States closed. Analyze the effects on different groups.

     Result: Buyers gained more choices and convenience. Entrepreneurs who started streaming companies earned profits and hired new workers. Rental store owners and workers lost income and had to find other work. In a market economy, innovation often replaces older products, and resources such as workers and buildings move to new uses.

   Teacher tip. Students often use "invention" and "innovation" as the same word. Keep asking, "Did people actually start using it?" Also watch for the idea that entrepreneurs are only famous inventors: most entrepreneurs open ordinary businesses, such as a restaurant, a lawn-care service or a repair shop, and many innovate in small ways.

   Young Edison as inventor and entrepreneur. Context note: Thomas Edison (1847-1931) later became famous for the phonograph and the electric light, but in 1868 he was a young telegraph operator in Boston. Sources 1 and 2 come from a 1910 biography written by Edison's lawyer, Frank Lewis Dyer, and the engineer Thomas Commerford Martin, with long quotations from Edison himself. Read Source 1 aloud. Glossary: "operative model" (a working machine), "financial backer" (a person who pays for a project and hopes to share in its success), "filibustering" (using long speeches or delays to stop a vote), "press operator" (a telegraph operator who sent news stories), "subserved the actual necessities of humanity" (met people's real needs).

   1[...] Edison worked out into an operative model his first invention, a vote-recorder, the first Edison patent, for which papers were executed on October 11, 1868, and which was taken out June 1, 1869, No. 90,646. The purpose of this particular device was to permit a vote in the National House of Representatives to be taken in a minute or so [...] Mr. Edison, in recalling the circumstances, says: "Roberts was the telegraph operator who was the financial backer to the extent of $100. The invention when completed was taken to Washington. I think it was exhibited before a committee that had something to do with the Capitol. The chairman of the committee, after seeing how quickly and perfectly it worked, said: 'Young man, if there is any invention on earth that we don't want down here, it is this. One of the greatest weapons in the hands of a minority to prevent bad legislation is filibustering on votes, and this instrument would prevent it.' I saw the truth of this, because as press operator I had taken miles of Congressional proceedings, and to this day an enormous amount of time is wasted during each session of the House in foolishly calling the members' names and recording and then adding their votes, when the whole operation could be done in almost a moment by merely pressing a particular button at each desk. For filibustering purposes, however, the present methods are most admirable." Edison determined from that time forth to devote his inventive faculties only to things for which there was a real, genuine demand, something that subserved the actual necessities of humanity.

   Then read Source 2. Glossary: "juncture" (moment), "stock ticker" (a telegraph machine that printed stock prices), "psychological moment" (the moment that matters most), "night force" (a night shift of workers), "foreman" (the boss of a group of workers), "vagaries" (strange mistakes).

   1At this juncture General Lefferts, as President of the Gold & Stock Telegraph Company, requested Edison to go to work on improving the stock ticker, furnishing the money; and the well-known "Universal" ticker, in wide-spread use in its day, was one result. Mr. Edison gives a graphic picture of the startling effect on his fortunes: "I made a great many inventions; one was the special ticker used for many years outside of New York in the large cities. This was made exceedingly simple, as they did not have the experts we had in New York to handle anything complicated. The same ticker was used on the London Stock Exchange. [...] He called me into his office, and said: 'Now, young man, I want to close up the matter of your inventions. How much do you think you should receive?' I had made up my mind that, taking into consideration the time and killing pace I was working at, I should be entitled to $5000, but could get along with $3000. When the psychological moment arrived, I hadn't the nerve to name such a large sum, so I said: 'Well, General, suppose you make me an offer.' Then he said: 'How would $40,000 strike you?' This caused me to come as near fainting as I ever got. [...]

   [...]

   2With quiet self-possession he seized his opportunity, began to buy machinery, rented a shop and got work for it. Moving quickly into a larger shop, Nos. 10 and 12 Ward Street, Newark, New Jersey, he secured large orders from General Lefferts to build stock tickers, and employed fifty men. As business increased he put on a night force, and was his own foreman on both shifts. [...] After a while Edison got a bookkeeper, whose vagaries made him look back with regret on the earlier, primitive method. "The first three months I had him go over the books to find out how much we had made. He reported $3000. I gave a supper to some of my men to celebrate this, only to be told two days afterward that he had made a mistake, and that we had lost $500; and then a few days after that he came to me again and said he was all mixed up, and now found that we had made over $7000." Edison changed bookkeepers, but never thereafter counted anything real profit until he had paid all his debts and had the profits in the bank.

   1. A working machine can still fail. Prompt: Source 1 says the vote-recorder worked "quickly and perfectly." Using the example of Ana's wagon, explain why a machine that works can still fail to sell. Teacher note: a market rewards what buyers want, not what is clever. Do not yet discuss the chairman's reason; students find it themselves in the quiz.
   2. Value to the buyer. Prompt: in Source 2, paragraph 1, Edison hoped for a few thousand dollars, and the company offered far more. Why might an invention be worth more to a buyer than the inventor's own time and trouble? Teacher note: the company could use the improved tickers in many offices for years, so their value to it depended on what they would earn, not on Edison's hours of work.
   3. Spending before earning. Prompt: in Source 2, paragraph 2, what did Edison spend money on before his customers paid him, and what could he lose? Teacher note: machinery, rent for a shop and then a larger one, and the pay of his workers; if orders stopped, he could lose that money. Spending first in the hope of profit is the entrepreneur's risk.
   4. Pair check. Pairs write one sentence that uses the words "risk" and "profit" to describe Edison's first months as a manufacturer. Collect the sentences; quiz questions 1-7 and 19 use Sources 1 and 2.

   How risky is starting a business? Source 3 is real data from the U.S. Bureau of Labor Statistics (BLS), a federal agency. An establishment is one business location, such as one store, office or workshop. The table follows every private-sector establishment that opened in the United States in the 12 months ending in March 2015 and counts how many were still open each March after that.

   Source 3: Establishments opened in the year ended March 2015, and how many survived (U.S. Bureau of Labor Statistics, Business Employment Dynamics, Table 7, real data)

   March of year	Establishments still open	Percent still open since opening	Average employees per surviving establishment
   March 2015	677,876	100.0%	4.4
   March 2016	539,701	79.6%	5.7
   March 2017	468,293	69.1%	6.6
   March 2018	416,438	61.4%	7.4
   March 2019	375,833	55.4%	8.1
   March 2020	340,281	50.2%	8.8
   March 2021	314,801	46.4%	8.9
   March 2022	295,667	43.6%	10.2
   March 2023	273,295	40.3%	10.7
   March 2024	253,300	37.4%	11.3
   March 2025	235,071	34.7%	11.7

   Real data: U.S. Bureau of Labor Statistics, Business Employment Dynamics, Table 7, Survival of private sector establishments by opening year (data through March 2025), bls.gov. The first row counts every establishment that opened during the 12 months ending in March 2015.

   Students answer on their own: (1) In one sentence, describe the overall pattern in the "percent still open" column. (2) Look at the last column. What happened to the size of the businesses that stayed open? (3) Write two sentences explaining what these data tell a person who is thinking about starting a business. Then compare the table with Diagram 1.

5. Closure10-15 minutes

   A young entrepreneur faces a rival. Introduce Source 4, an invented scenario, for the quiz and homework. Students read it and underline every cost Dana pays and every risk she takes.

   1Invented scenario, written for this page. Riverton is a fictional town of about 40,000 people, where many students ride bikes to school. Dana Ruiz, a 26-year-old bike mechanic, noticed that her customers' battery lights kept dying on dark winter evenings.

   2Dana designed a handlebar light that charges itself while the rider pedals. She called it the SpinLite. To start her business she needed $6,000 for a plastic mold and tools. She used $2,000 of her savings and borrowed $4,000 from a credit union (a bank owned by its members), which she must repay even if the business fails. Each SpinLite costs her $9 for parts and assembly, and she sells it for $24.

   3In her first year Dana sold 650 lights to riders and to two local bike shops. She also applied for a patent on her charging design.

   4In her second year a large company began selling a different self-charging light for $18. Dana's sales slowed. She found a supplier that sells parts in bulk and built a simple wooden jig (a frame that holds the parts in place) so she could put each light together faster. Her cost fell to $7 a light, and she lowered her price to $18 to match the rival. She also started work on a new model with a built-in brake light.

   Exit ticket: Finish the sentence: "In a market economy, innovation matters because ___, and entrepreneurs matter because ___."

   Teacher note on the sources: Sources 1 and 2 are quoted exactly from the 1910 biography. One author was Edison's own lawyer, and Edison told these stories about forty years after the events, so they show how Edison remembered his early career, not a neutral record; the dollar amounts are as he recalled them. Source 3 is real BLS data, quoted exactly. Source 4, Leo, the bakery and every number in the worked examples and activities are invented. The lesson does not take a position on any current law about patents, taxes or small business.
