Lesson Report:
**Title:
Markets, Efficiency, and When Public Policy Steps In**
In this session, students were introduced to basic economic concepts—markets, efficiency, and market failure—as a foundation for understanding why and when governments intervene through public policy. Using a simple water-bottle example, the class worked through how idealized “free market� exchanges are supposed to function, and then systematically explored the ways those exchanges can break down. The lesson concluded by mapping specific public policies (e.g., labeling, free water, safety standards) onto different types of market failures, drawing on key ideas from Deborah Stone’s critique of market-centric thinking.

## Topics Covered (Chronological, with Detailed Activity/Content Notes)
### 1. Framing the Week: Why Talk About Markets in a Public Policy Class?
– **Check of prior knowledge**
– The instructor informally surveyed the class: Who has taken economics/political economy before?
– Noted institutional context: AUCA apparently does not have a formal econ department or intro-to-econ course, so the instructor signaled this would *not* be a full econ course, but a targeted introduction to selected economic ideas relevant to public policy.
– **Motivation for the topic**
– Core rationale presented:
– To understand how **government** solves problems, students need to understand the **parallel system**: how **markets** (and the broader economy) are *supposed* to solve problems.
– Public policy is often justified as a response to **market failures**—situations where markets do not deliver acceptable solutions.
– Key guiding questions for the session:
– What is a *market*?
– Under what conditions does a market transaction “work wellâ€� (i.e., is efficient)?
– Under what conditions does it fail, and why might government need to step in?
—
### 2. Defining “Market�: Individual Writing and Class Brainstorm
– **Individual notebook prompt**
– Students were asked to answer, in their notebooks:
– *“When you hear the word market, what is a market to you? Not necessarily a physical bazaar, but in a general sense.â€�*
– Students had 1–2 minutes to jot down short definitions or descriptive phrases.
– **Whole-class brainstorm & concept mapping**
– The instructor collected and wrote key terms/phrases on the board as students offered ideas. Concepts included:
– **Place/system for exchange** of goods and services.
– **Buying and selling**; **transactions**.
– **Prices** and their “control.â€�
– **Capitalism** / **free market** (idea that markets are fundamental to capitalism).
– **Households** as participants (buyers/sellers).
– **Profit** as a main motivator of market participation.
– **Government control/regulation** of markets.
– **Economy** and **industry** as systems built out of markets.
– **Networking**/**networks of buyers and sellers** (markets need more than two isolated individuals; they need a structured network).
– **Supply and demand** (basic econ 101 concept, flagged but not deeply developed).
– **Trade/exchange**, including mention of **stocks**, **bonds**, **dividends** (explicitly noted as *out of scope* for this course, but still examples of market exchange).
– **Working definition synthesized by instructor**
– In general, a market was framed as:
– A **place or system** where people exchange **things of value** (goods/services) with each other.
– Individuals trade what is **less valuable to them** personally for something that is **more valuable (or at least equally valuable)**, from their own perspective.
– This mutual benefit of exchange becomes the basis for later discussion of **efficiency** and **market “success.â€�**
—
### 3. Core Example: Aydana’s Water Bottle Transaction
– **Setup of the example**
– Scenario: Aydana goes to Coffee Mania (near campus) and buys a **500 ml bottle of water**.
– She pays **30 soms** and receives the water.
– Class asked: *“In this world where that exchange occurs, is everybody happy?â€�*
– Mixed responses: some yes, some no.
– **Analysis of the “yes, everyone is happyâ€� view**
– Instructor’s unpacking:
– Aydana values **water + bottle** more than 30 soms, otherwise she wouldn’t pay.
– The **seller** values **30 soms** more than one more bottle on the shelf.
– Under standard market logic, this is a **mutually beneficial exchange**.
– This becomes the **“perfect worldâ€� reference case** for a successful market transaction under capitalism.
– **Transition to skepticism**
– A dissenting view (e.g., Adelia) suggested that sometimes not everyone is happy—e.g., if the buyer cannot really afford to forgo water.
– This foreshadowed:
– Situations where *necessity* limits choice.
– Situations where buyers lack **information** or **alternatives**.
– The idea that what appears efficient at first glance can mask underlying problems.
—
### 4. Introducing Market Efficiency (General Concept → Market Application)
– **General-language definition of efficiency**
– Students asked: *“If something is efficient, what does that mean?â€�*
– Student answers:
– “It works well.â€�
– “It works as expected / reliably.â€�
– “It’s productive.â€�
– Instructor elaboration:
– In everyday usage, efficiency often means:
– Performing a task **smoothly and reliably**.
– Using the **minimum possible resources** (time, energy, money, etc.) to achieve the desired result.
– Examples:
– An “efficient runnerâ€� uses minimal calories for a given speed.
– A “time-efficientâ€� person accomplishes tasks in minimal time.
– **Market-specific definition of efficiency**
– Applied to markets/transactions:
– A transaction or firm is **efficient** if it:
– **Gets the job done (delivers the good/service)**
– For the **lowest possible cost / minimal use of resources**.
– In terms of buyer/seller:
– A transaction is efficient when **all sides get the maximum value for the minimum cost** *relative to alternatives*.
– Noted that:
– **Efficiency is relative** (depends on context and available options).
– There are tensions: pushing efficiency “ruthlesslyâ€� may sacrifice other values we care about (fairness, safety, equity, sustainability).
—
### 5. Partner Exercise: “Breaking� the Efficiency of the Water Transaction
– **Task**
– With a partner, students were asked to think of **2–3 ways** to make the Aydana–water transaction **inefficient** or unsatisfactory for one or both sides.
– Guiding question:
– *“What circumstances would need to happen so that both parties (or at least one party) are no longer happy with the deal?â€�*
– Examples students likely discussed (some referenced later):
– Water is spoiled, tastes bad, or is not as advertised.
– Bottle volume is less than labeled; quality is lower.
– Price is unfairly high, no alternatives available, etc.
– **Purpose**
– This exercise was to:
– Prime students to think concretely about **market failures** at the level of **individual transactions**.
– Prepare them for Stone’s three categories of market problems (information, voluntarism, rationality).

### 6. Linking Markets to Public Policy: Why Government Exists in a Market Society
– **Role of markets in “capitalismâ€�**
– Instructor noted that, colloquially, “we live in capitalism.â€�
– In more formal terms:
– Our society expects **markets** to solve many everyday problems:
– Thirst → buy water.
– Hunger → buy food/burgers.
– Desire for variety → emergence of many restaurants/shops through entrepreneurs responding to demand.
– **How markets are supposed to solve problems**
– Example revisited:
– People with abundant water (e.g., owners of springs/lakes) exchange **excess water** for money with people who **need water**.
– The exchange is framed as **mutually beneficial** and **voluntary**.
– Over time, this pattern generates a system where supply meets demand *without central coordination*, according to standard market theory.
– **Where public policy comes in**
– Key claim:
– **Public policy exists to fill gaps where the market cannot or does not solve particular problems.**
– Two important distinctions:
– **Conditions** vs. **problems**:
– A condition becomes a public **problem** when society decides it should not simply be “enduredâ€� and that **collective/government action** is appropriate.
– Many public policy issues are **responses to market failures**:
– Cases where relying on markets alone produces outcomes that are widely judged as unacceptable (unmet basic needs, unsafe products, exploitation, etc.).
– The day’s **main goal**:
– Identify **where and how markets fail**, especially at the micro-level of transactions, to set up deeper analysis of government interventions later.

### 7. Introducing Stone’s Critique: Three Sources of Market Inefficiency
– **Reading context**
– Instructor referenced *Deborah Stone* (likely from *Policy Paradox*).
– Admitted the reading had not yet been posted; promised to post it that evening (~7 pages) and encouraged students to read it before Thursday.
– Framed Stone as:
– Critiquing the view of markets as **perfect, self-correcting problem-solvers**.
– Asking: under what conditions **must** government intervene?
– **Stone’s three main problems/assumptions in markets**
– 1. **Asymmetry of Information**
– Clarification of terms:
– **Symmetry**: same on both sides.
– **Asymmetry**: unequal/different on each side.
– In market context:
– One side has **more or better information** than the other (or information is unequally distributed).
– This can be **intentional** (deception, withholding info) or **unintentional** (accidental ignorance).
– Application to the water example:
– Suppose the water bottle was left in the August sun for hours; plastic leached into the water; it tastes terrible.
– If the **seller knows** or *could* know this but the buyer doesn’t, the buyer overpays relative to the actual value they would assign if fully informed.
– Even if the seller *didn’t* realize the water was spoiled, the transaction is still **inefficient** because the buyer paid for something different from what they intended.
– Student-supplied variants:
– **Bad/low-quality water** (e.g., unsafe or “grossâ€� water) where the buyer isn’t told.
– Bottles not matching their stated **volume** or condition (e.g., dusty/contaminated bottles).
– 2. **Voluntarism (or Lack of Real Choice)**
– Scenario:
– Aydana is in the **desert**, desperately thirsty.
– There is **only one vendor**, selling 500 ml water for **5,000 soms**.
– Formally, she can “chooseâ€� not to buy and die of thirst, but this is not a **meaningful / fair** choice.
– Core ideas:
– Standard market theory assumes:
– People **freely choose** whether and from whom to buy.
– There is **competition** among sellers, which disciplines prices and quality.
– In reality:
– Some situations provide **no real alternative**:
– Essential goods (e.g., water) where opting out is not realistic.
– **Monopolies** or near-monopolies where only one seller (or cartel) controls supply.
– In these conditions, the seller can:
– Charge a highly inflated price.
– Offer lower-quality goods.
– Exploit buyers’ lack of alternatives.
– This undermines **voluntariness** and is considered another source of **inefficiency**/market failure.
– Student-related examples:
– Places where people must buy water from limited sources at inflated prices; consumers and intermediaries all forced into a bad deal.
– Situations where a few suppliers control all the water going to stores; stores and consumers face higher prices and no real alternatives.
– Taxes were mentioned briefly, but the instructor noted that taxation is a **government variable**, not purely a market variable; still relevant to constraints people face.
– 3. **Rationality (Limits of Rational Decision-Making)**
– Instructor’s hypothetical:
– Assume Aydana is a passionate **BTS** fan.
– Legenda releases a **special BTS-branded water bottle** for **150 soms**.
– The water itself is **identical** to a standard 30-som bottle, but the label has BTS images.
– If Aydana buys the 150-som bottle purely for the label:
– Her thirst is satisfied no better than with the cheaper bottle.
– Yet she pays a **premium** for non-material/emotional reasons.
– Broader point:
– Economic models often assume people are **perfectly rational**, always seeking to **maximize material utility**.
– In reality:
– People have **emotional, symbolic, or status-based reasons** for purchasing.
– They often do **not** search exhaustively for the best deal.
– Couponing example:
– A purely rational consumer (in narrow econ terms) would:
– Scan apps, flyers, websites, magazines.
– Hunt all discounts and coupons.
– Plan shopping to minimize cost.
– In practice, most people:
– Don’t invest hours in this, even when it could save money.
– May simply not want to, or value their time/mental energy more than marginal savings.
– This gap between theoretical rationality and actual behavior is another way transactions deviate from the ideal of efficiency.
– Student contributions:
– Discussion of:
– Buying “fashionableâ€� or branded items at premiums when cheaper, functionally equivalent goods exist.
– Seasonal shopping strategies (buying winter clothes off-season to save money) as rational strategies—but noted that many people *don’t* do this even when it might be efficient.
– Overconfidence in labels/ads that make consumers believe they’re acting rationally when they may be driven by marketing or cognitive biases.
—
### 8. Sorting Exercise: Categorizing Inefficiencies into Stone’s Three Types
– **Task**
– Students revisited their initial “how to break efficiencyâ€� examples (from the water bottle transaction) and:
– Sorted each example into one of the three categories:
– **Information asymmetry**
– **Voluntarism** (lack of real choice/competition)
– **Rationality limits**
– Justified why their example fits that category.
– **Clarifications & discussions**
– **Information asymmetry examples**:
– Seller hiding or failing to disclose:
– Poor water quality, contamination, or stale water.
– Misleading content (e.g., volume less than label).
– Emphasis: Even if not intentional, the unequal information means the buyer cannot accurately value the product.
– **Voluntarism examples**:
– Monopolistic settings where:
– Only one supplier exists; buyers and/or retailers must accept inflated wholesale prices that then pass to consumers.
– Essential goods (like water) leave consumers with no realistic “opt-out.â€�
– **Rationality examples**:
– Less concrete from students, but guided toward:
– Paying extra for flavored/“premiumâ€� water even though it solves thirst no better.
– Not using available discount apps/coupons out of disinterest or inconvenience.
– Instructor underlined that this is about **behavioral deviations** from the hyper-rational “economic manâ€� model.

### 9. From Market Failures to Policy Solutions: Policy-Mapping Activity
– **Transition**
– Instructor emphasized that:
– **All** public policy issues discussed so far can be viewed as attempts to **correct** or **mitigate** market failures in one (or more) of Stone’s three domains.
– Students were asked to connect:
– **Specific policies** to the **type of market failure** they address.
– **Clear written example from instructor (information asymmetry)**
– Policy: **Production dates on milk** (and similar foods).
– Government requires producers to label **date of production** (and implicitly expiration).
– Problem addressed:
– Without these dates, consumers cannot know whether milk is fresh or spoiled → **information asymmetry**.
– Buyers might unknowingly pay full price for spoiled or soon-to-spoil milk.
– The labeling requirement **harmonizes information** between buyer and seller, improving transaction efficiency and safety.
– **Group task**
– With partners (and with laptops closed—explicitly asked not to use ChatGPT), students were to:
– Identify **one real-world policy** (law, regulation, or public program) addressing:
1. An **information** problem,
2. A **voluntarism** problem,
3. A **rationality** problem.
– Clarify:
– What **problem** it addresses.
– How it fits into the chosen category.
—
### 10. Whole-Class Policy Examples and Instructor Commentary
The class shared several policy examples and discussed how they fit into Stone’s framework.
– **Voluntarism-related policies**
– **Free drinking water in public spaces**
– Example: Public fountains or free potable water sources.
– Problem addressed:
– People **must** drink water; they cannot reasonably “chooseâ€� not to.
– Some may lack the ability to pay for bottled water; in some locations, water vendors may have de facto monopolies.
– How it addresses voluntarism:
– By providing **free public water**, the government:
– Ensures people are **not forced** to buy water under coercive conditions.
– Introduces a **non-market option**, increasing real choice.
– Result: People are less vulnerable to exploitation by high-priced vendors.
– **Seatbelt requirements in cars** (discussion around category)
– Students suggested that lack of seatbelts is a policy problem.
– Instructor reframed:
– Car manufacturers may choose not to install seatbelts to save costs → rational from a profit standpoint, but socially harmful.
– Consumers cannot easily “build their own carâ€� with safer features if no manufacturer offers them.
– Government response:
– Laws requiring **all cars sold** to have seatbelts (and other safety standards).
– Category fit:
– Primarily a **voluntarism** problem, because:
– Buyers lack meaningful alternatives if no manufacturer offers safer options.
– Government intervention creates a **baseline safety standard** so consumers are not forced into unsafe choices.
– **Information-related policies**
– **Ingredient and content labeling on beverages and foods**
– Students cited:
– Labels listing **ingredients**, **additives**, and other details.
– **Quality assurance stamps** or certifications.
– Problem addressed:
– Without ingredient lists and quality marks, consumers cannot:
– Identify what they are consuming (e.g., potential allergens, undesired animal products).
– Distinguish between higher and lower quality products.
– This creates **information asymmetry**: producers know the composition; consumers do not.
– Policy function:
– Government requires accurate labeling of:
– Ingredients.
– Nutritional information.
– Sometimes origin or specific quality standards.
– This allows consumers to adjust their willingness to pay and choose between competitors more accurately.
– **“Good qualityâ€� government marks or certification labels**
– Example: Government or standards agencies placing a logo or mark showing that a product meets certain safety or quality criteria.
– Problem addressed:
– Consumers cannot directly test each bottle of water or food item for safety.
– Certification reduces uncertainty, again improving **information symmetry**.
– **Rationality-related policies (less fully developed in class)**
– Students proposed several ideas; instructor evaluated where they best fit.
– General conceptual direction:
– Policies that:
– **Nudge** people away from self-harming choices that stem from limited rationality (e.g., excessive risky consumption, ignoring safety).
– Could include (though not fully elaborated in transcript):
– Warning labels (e.g., tobacco, alcohol).
– Restrictions on especially dangerous products.
– Instructor emphasized that:
– Many seemingly “irrationalâ€� consumer choices are fully rational from individuals’ broader value frameworks (e.g., paying for BTS-branded items as expression of identity), so classification is not always straightforward.
– **Summative link**
– Instructor reiterated:
– Each of these policies can be viewed as designed to **correct** some defect in the idealized market model.
– When markets fail to solve problems fairly or effectively, these failures are translated into **policy problems** that governments attempt to address.

## Actionable Items (for the Instructor)
### High Urgency (Before Next Class)
– **Post and reference the Stone reading**
– Ensure the promised **Stone reading (approx. 7 pages)** is uploaded to the LMS or distributed as stated.
– Consider including:
– Clear citation and page numbers.
– A brief note tying it directly to:
– Information asymmetry,
– Voluntarism,
– Rationality/“rational actorâ€� critique.
– At the start of the next class, explicitly check who has read it and quickly review key arguments to solidify the conceptual foundations introduced orally.
– **Clarify expectations for the Stone-based discussion**
– Prepare 2–3 **guiding questions** for the next session that directly connect Stone’s text to:
– The water-bottle example.
– Students’ own policy examples (labeling, free water, seatbelts, etc.).
– This will help students see the reading as a tool for understanding policy design rather than as abstract theory.
### Medium Urgency (Next 1–2 Classes)
– **Revisit and formalize the concept of “market failureâ€�**
– Explicitly define **market failure** (in contrast to individual transaction inefficiency) and list:
– Information asymmetry.
– Lack of voluntarism/competitive choice.
– Limits of rationality.
– Optionally, transition towards broader econ-style categories (externalities, public goods, etc.) if these will be used later, and connect them conceptually to Stone’s three.
– **Follow up on rationality-based policy examples**
– Since students struggled more with **rationality** than with information/voluntarism:
– Bring a few **concrete, clear examples**:
– Sin taxes and warning labels (tobacco, alcohol).
– Restrictions on advertising to children.
– Default rules in retirement savings or organ donation.
– Have students discuss:
– To what extent these address **irrational behavior** vs. information problems or voluntarism issues.
### Lower Urgency / Ongoing
– **Attendance follow-up**
– Note the absence of **Aziriyat**:
– If absences are tracked formally, update your records.
– If needed, check in briefly by email or LMS message regarding missed content, particularly the introduction of Stone’s framework.
– **Consolidate student-generated examples for future reference**
– Consider briefly re-listing student examples next class (production dates, ingredient labels, free water, seatbelts, etc.) as a **reference map**:
– This will give you a reusable in-class example bank when later discussing:
– Regulation,
– Consumer protection,
– Social welfare programs,
– And the condition→problem→policy chain.
– **Align upcoming topics with this foundation**
– In planning subsequent lessons (e.g., on health policy, social welfare, environmental regulation), explicitly:
– Identify which parts of Stone’s three-problem framework and which type of market failure each case illustrates.
– Refer back to the **Aydana water-bottle** archetype to help students bridge abstract theory and real policies.
Homework Instructions:
ASSIGNMENT #1: Stone reading on market failures and public policy
You will read a short excerpt by Stone that deepens today’s introduction to markets, efficiency, and market failures. This reading helps you understand, in a more systematic way, *when* markets fail to solve social problems on their own and *why* governments might need to step in.
Instructions:
1. **Locate and download the reading**
1.1. Find the assigned Stone reading that will be posted by the instructor (“I know I didn’t post the Stone reading over the weekend. I will post the Stone reading tonight. It’s going to be, I think, seven pages.â€�).
1.2. Download or open the file so you can annotate it (digitally or on paper).
2. **Set aside focused reading time before the next class**
2.1. Plan for about 30–40 minutes of uninterrupted time to read roughly seven pages carefully.
2.2. Aim to complete the reading *before Thursday’s class*, since the instructor said, “If you have time to blitz through it before Thursday, that would be great,� and class discussion will build on it.
3. **Read with today’s key concepts in mind**
As you read, continually connect Stone’s arguments back to the examples and terminology from class, especially:
– The **water bottle example** (Aydana buying water from Coffee Mania, or in the desert).
– The idea of **market efficiency**: “all sides get the maximum value for the minimum cost.â€�
– The three reasons transactions/markets can become **inefficient** that were introduced in class:
– **Asymmetry of information** (one side knows more or has better information than the other).
– **Lack of voluntarism** (when you effectively *don’t* have a real choice, e.g., the desert scenario).
– **Limits of rationality** (people don’t always behave like perfectly rational calculators trying to get “the most for the leastâ€�).
4. **Identify Stone’s main claims about markets and government**
4.1. As you read, underline or highlight places where Stone:
– Criticizes the idea of the market as a *perfect* or *self-correcting* problem-solver.
– Explains why markets sometimes **fail to solve certain social problems**.
– Suggests or implies **why and when governments might need to intervene**.
4.2. In your notes (separate from the text), write **2–3 bullet points** that summarize, in your own words, Stone’s overall answer to this question:
– *“At what point does a government need to step in to solve a problem that the market can’t?â€�* (This was the framing given in class.)
5. **Connect Stone’s three problem types to our class terminology**
Stone identifies three main reasons why markets/transactions are problematic or inefficient. For each of the three categories discussed in class, do the following in your notes:
5.1. **Asymmetry of information**
– Find where Stone talks about situations where **buyers and sellers don’t have the same information**.
– In your notebook, write:
1. Stone’s idea in one or two sentences **in your own words**.
2. One example **from the reading** that illustrates information asymmetry.
3. One example **from class** or your own life, such as:
– The water that “tastes like plasticâ€� because it sat in the August sun, but the buyer didn’t know.
– Milk or beverage labels where the **production date** and **ingredients** are needed so buyers know if the product is good or bad.
5.2. **Voluntarism (having a real choice)**
– Find where Stone discusses situations in which people **cannot realistically choose** whether or from whom to buy.
– In your notes, for this category, write:
1. Her definition/description in your own words.
2. One example from the reading.
3. One example from class discussions, such as:
– Aydana in the **desert**, where there is only one seller charging 5,000 soms for water, and she **must** buy or face serious harm.
– Public policies that increase choice, like **free public drinking fountains**, which reduce people’s dependence on bottled water when they can’t afford it.
5.3. **Rationality (or the limits of rationality)**
– Find Stone’s discussion of how people are **not perfectly rational calculators** and often make choices for emotional, social, or convenience reasons.
– In your notes, write:
1. Her main point about rationality in your own words.
2. One example from the reading where people’s behavior doesn’t match “purely rational� economic assumptions.
3. One example connected to class, such as:
– Paying more for a **limited-edition BTS-branded water bottle** even though the water is identical.
– Not spending hours searching for all possible discounts and coupons, even though a “perfectly rationalâ€� consumer would, because in reality people don’t optimize like computers.
6. **Identify policy solutions linked to each problem type**
Remember, the instructor emphasized that **public policy exists to fill the gaps where the market cannot solve a particular problem**. As you read:
6.1. Note any laws, regulations, or government programs Stone mentions that are designed to fix:
– Information problems (e.g., mandatory labeling, disclosure rules).
– Voluntarism problems (e.g., ensuring access to basic goods like water or safety standards when there’s no real alternative).
– Rationality problems (e.g., policies that protect people from predictable decision-making biases or from being exploited).
6.2. For each of the three categories, try to list **at least one policy example** either from Stone or from our class discussion:
– Information: production dates on milk, ingredient lists, government quality labels on beverages or food.
– Voluntarism: free drinking water in public spaces; mandatory seatbelts in cars when no car company would voluntarily include them.
– Rationality: any policy that recognizes people will not act like perfect optimizers and tries to protect or guide them.
7. **Prepare to use your notes in the next class**
7.1. Bring your notes (digital or paper) to the next session.
7.2. Be ready to:
– Explain, in your own words, the **three reasons Stone says markets/transactions fail**.
– Connect Stone’s framework back to the **water bottle example** and to **real policies** (like labeling rules, public water access, seatbelt laws).
– Discuss how these examples show the boundary between **“what the market can solveâ€�** and **“what the government needs to solveâ€�**.
By completing this reading in this structured way, you will be better prepared to recognize real-world market failures and understand why they become **public policy problems** rather than just individual misfortunes.
