## 经济代写|微观经济学代写Microeconomics代考|Smart for One, Dumb for All

The socially optimal quantity of any good is the quantity that maximizes the total economic surplus that results from producing and consuming the good. From the CostBenefit Principle, we know that we should keep expanding production of the good as long as its marginal benefit is at least as great as its marginal cost. This means that the socially optimal quantity is that level for which the marginal cost and marginal benefit of the good are the same.

When the quantity of a good is less than the socially optimal quantity, boosting its production will increase total economic surplus. By the same token, when the quantity of a good exceeds the socially optimal quantity, reducing its production will increase total economic surplus. Efficiency, or economic efficiency, occurs when all goods and services in the economy are produced and consumed at their respective socially optimal levels.

Efficiency is an important social goal. Failure to achieve efficiency means that total economic surplus is smaller than it could have been. Movements toward efficiency make the total economic pie larger, making it possible for everyone to have a larger slice.

Is the market equilibrium quantity of a good efficient? That is, does it maximize the total economic surplus received by participants in the market for that good? When the private market for a given good is in equilibrium, we can say that the cost to the seller of producing an additional unit of the good is the same as the benefit to the buyer of having an additional unit. If all costs of producing the good are borne directly by sellers, and if all benefits from the good accrue directly to buyers, it follows that the market equilibrium quantity of the good will equate the marginal cost and marginal benefit of the good. And this means that the equilibrium quantity also maximizes total economic surplus.

But sometimes the production of a good entails costs that fall on people other than those who sell the good. This will be true, for instance, for goods whose production generates significant levels of environmental pollution. As extra units of these goods are produced, the extra pollution harms other people besides sellers. In the market equilibrium for such goods, the benefit to buyers of the last good produced is, as before, equal to the cost incurred by sellers to produce that good. But since producing that good also imposes pollution costs on others, we know that the full marginal cost of the last unit produced-the seller’s private marginal cost plus the marginal pollution cost borne by others-must be higher than the benefit of the last unit produced. So, in this case, the market equilibrium quantity of the good will be larger than the socially optimal quantity. Total economic surplus would be higher if output of the good were lower. Yet neither sellers nor buyers have any incentive to alter their behavior.

## 经济代写|微观经济学代写Microeconomics代考|The Origins of Demand

How much are you willing to pay for the latest Beyoncé album? The answer will clearly depend on how you feel about her music. To her diehard fans, buying the new release might seem absolutely essential; they’d pay a steep price indeed. But those who don’t like her music may be unwilling to buy it at any price.

Wants (also called “preferences” or “tastes”) are clearly an important determinant of a consumer’s reservation price for a good. But that raises the question of where wants come from. Many tastes-such as the taste for water on a hot day or for a comfortable place to sleep at night=are largely biological in origin. But many others are heavily shaped by culture, and even basic cravings may be socially molded. For example, people raised in southern India develop a taste for hot curry dishes, while those raised in France generally prefer milder foods.

Tastes for some items may remain stable for many years, but tastes for others may be highly volatile. Although books about the Titanic disaster have been continuously available since the vessel sank in spring 1912, not until the appearance of James Cameron’s blockbuster film did these books begin to sell in large quantities. In spring 1998, 5 of the 15 books on The New York Times paperback bestseller list were about the Titanic itself or one of the actors in the film. Yet none of these books, or any other book about the Titanic, has made the bestseller list in the years since then. Still, echoes of the film continue to reverberate in the marketplace. In the years since its release, for example, demand for ocean cruises has grown sharply, and several television networks have introduced shows set on cruise ships.

Peer influence provides another example of how social forces often influence demand. Indeed, it is often the most important single determinant of demand. For instance, if our goal is to predict whether a young man will purchase an illegal recreational drug, knowing how much income he has is not very helpful. Knowing the prices of whiskey and other legal substitutes for illicit drugs also tells us little. Although these factors do influence purchase decisions, by themselves they are weak predictors. But if we know that most of the young man’s best friends are heavy drug users, there’s a reasonably good chance that he’ll use drugs as well.

Another important way in which social forces shape demand is in the relatively common desire to consume goods and services that are recognized as the best of their kind. For instance, many people want to see LeBron James play basketball not just because of his skills on the court, but because he is widely regarded as one of the best basketball players of all time.

Consider, too, the decision of how much to spend on an interview suit. Employment counselors never tire of reminding us that making a good first impression is extremely important when you go for a job interview. At the very least, that means showing up in a suit that looks good. But looking good is a relative concept. If everyone else shows up in a $\$ 200$suit, you’ll look good if you show up in a$\$300$ suit. But you won’t look as good in that same $\$ 300$suit if everyone else shows up in suits costing$\$1,000$. The amount you’ll choose to spend on an interview suit, then, clearly depends on how much others in your circle are spending.
