Sometimes, lawmakers determine that the market price is “too high” for consumers to pay, so they use their power to impose a ceiling on price below the market equilibrium price.

Important specific elasticities include own-price elasticity of demand, income elasticity of demand, and cross-price elasticity of demand. <span>Based on algebraic sign and magnitude of the various elasticities, goods can be classified into groups.

Goods with positive income elasticity of demand are called normal goods, and those with negative income elasticity of demand are called inferior goods. Two goods with negative cross-price elasticity of demand—a drop in the price of one good causes an increase in demand for the other good—are called complements. Goods with positive cross-price elasticity of demand—a drop in the price of one good causes a decrease in demand for the other—are called substitutes.

Sellers’ behavior is captured in the supply function and its graphical equivalent, the supply curve. This curve shows simultaneously the lowest price sellers are willing to accept for each quantity and the highest quantity sellers are willing to offer at each price. If, at a given quantity, the highest price that buyers are willing to pay is equal to the lowest price that sellers are willing to accept, we say the market has reached it

SUMMARY
ven price, the quantity demanded exceeds the quantity supplied, there is excess demand and price will rise. If, at a given price, the quantity supplied exceeds the quantity demanded, there is excess supply and price will fall. <span>Sometimes auctions are used to seek equilibrium prices. Common value auctions sell items that have the same value to all bidders, but bidders can only estimate that value before the auction is completed. Overly optimistic bidders overestimate the true value and end up paying a price greater than that value. This result is known as the winner’s curse. Private value auctions sell items that (generally) have a unique subjective value for each bidder. Ascending price auctions use an auctioneer to call out ever increasing prices until the last, highest bidder ultimately pays his/her bid price and buys the item. Descending price, or Dutch, auctions begin at a very high price and then reduce that price until one bidder is willing to buy at that price. Second price sealed bid auctions are sometimes used to induce bidders to reveal their true reservation prices in private value auctions. Treasury notes and some other financial instruments are sold using a form of Dutch auction (called a single price auction) in which competitive and non-competitive bids are arrayed in descending price (increasing yield) order. The winning bidders all pay the same price, but marginal bidders might not be able to fill their entire order at the market clearing price. Markets that work freely can optimize society’s welfare, as measured by consumer surplus and producer surplus. Consumer surplus is the difference between the total value

#cfa #cfa-level-1 #economics #microeconomics #reading-14-demand-and-supply-analysis-consumer-demand #study-session-4-microeconomics-analysis

By now it should be clear that economists are model builders. In the previous reading, we examined one of their most fundamental models, the model of demand and supply. And as we have seen, models begin with simplifying assumptions and then find the implications that can then be compared to real-world observations as a test of the model’s usefulness. In the model of demand and supply, we assumed the existence of a demand curve and a supply curve, as well as their respective negative and positive slopes. That simple model yielded some very powerful implications about how markets work, but we can delve even more deeply to explore the underpinnings of demand and supply. In this reading, we examine the theory of the consumer as a way of understanding where consumer demand curves originate. In a subsequent reading, the origins of the supply curve are sought in presenting the theory of the firm. This reading is organized as follows: Section 2 describes consumer choice theory in more detail. Section 3 introd

#cfa #cfa-level-1 #economics #microeconomics #reading-14-demand-and-supply-analysis-consumer-demand #section-2-consumer-theory-from-preferences-to-demand-function #study-session-4-microeconomics-analysis

The introduction to demand and supply analysis in the previous reading basically assumed that the demand function exists, and focused on understanding its various characteristics and manifestations. In this reading, we address the foundations of demand and supply analysis and seek to understand the sources of consumer demand through the theory of the consumer, also known as consumer choice theory. Consumer choice theory can be defined as the branch of microeconomics that relates consumer demand curves to consumer preferences. Consumer choice theory begins with a fundamental model of how consumer preferences and tastes might be represented. It explores consumers’ willingness to trade off between two goods (or two baskets of goods), both of which the consumer finds beneficial. Consumer choice theory then recognizes that to consume a set of goods and services, consumers must purchase them at given market prices and with a limited income. In effect, consumer choice theory first models what the consumer would li

#cfa #cfa-level-1 #economics #microeconomics #reading-14-demand-and-supply-analysis-consumer-demand #section-3-utility-theory #study-session-4

At the foundation of consumer behavior theory is the assumption that the consumer knows his or her own tastes and preferences and tends to take rational actions that result in a more preferred consumption “bundle” over a less preferred bundle. To build a consistent model of consumer choice, we need to begin with a few assumptions about preferences. 3.1. Axioms of the Theory of Consumer Choice First, let us be clear about the consumption opportunities over which the consumer is assumed to have preferences. We define a consumption bundle or consumption basket as a specific combination of the goods and services that the consumer would like to consume. We could almost literally conceive of a basket containing a given amount of, say, shoes, pizza, medical care, theater tickets, piano lessons, and all the other things that a consumer might enjoy consuming. Each of those goods and services can be represented in a given basket by a non-negative quantity, respectively, of all the possible goods and

Armed with the assumptions of completeness, transitivity, and non-satiation, we ask whether there might be a way for a given consumer to represent his own preferences in a consistent manner. Let us consider presenting him with all possible bundles of all the possible goods and services he could consider. Now suppose we give him paper and pencil and ask him to assign a number to each of the bundles. (The assumption of completeness ensures that he, in fact, could do that.) All he must do is write a number on a paper and lay it on each of the bundles. The only restrictions are these: Comparing any two bundles, if he prefers one to the other, he must assign a higher number to the bundle he prefers. And if he is indifferent between them, he must assign the same number to both. Other than that, he is free to begin with any number he wants for the first bundle he considers. In this way, he is simply ordering the bundles according to his preferences over them.

Now suppose we give him paper and pencil and ask him to assign a number to each of the bundles. (The assumption of completeness ensures that he, in fact, could do that.) All he must do is write a number on a paper and lay it on each of the bundles. The only restrictions are these: Comparing any two bundles, if he prefers one to the other, he must assign a higher number to the bundle he prefers. And if he is indifferent between them, he must assign the same number to both. Other than that, he is free to begin with any number he wants for the first bundle he considers. In this way, he is simply ordering the bundles according to his preferences over them. Of course, each of these possible bundles has a specific quantity of each of the goods and services.

The utility of a bundle containing 4 ounces of wine along with 2 slices of bread would equal 8 utils, and it would rank lower than a bundle containing 3 ounces of wine along with 3 slices of bread, which would yield 9 utils.

Tom Warren currently has 50 blueberries and 20 peanuts. His marginal rate of substitution of peanuts for blueberries, MRSpb equals 4, and his indifference curves are strictly convex.

Determine whether Warren would be willing to trade at the rate of 3 of his blueberries in exchange for 1 more peanut.

Solution

MRSpb = 4 means that Warren would be willing to give up 4 blueberries for 1 peanut, at that point. He clearly would be willing to give up blueberries at a rate less than that, namely, 3-to-1.

Tom Warren currently has 50 blueberries and 20 peanuts. His marginal rate of substitution of peanuts for blueberries, MRSpb equals 4, and his indifference curves are strictly convex.

1. Suppose that Warren is indifferent between his current bundle and one containing 40 blueberries and 25 peanuts. Describe Warren’s MRSpb evaluated at the new bundle.

Solution

The new bundle has more peanuts and fewer blueberries than the original one, and Warren is indifferent between the two, meaning that both bundles lie on the same indifference curve, where blueberries are plotted on the vertical axis and peanuts on the horizontal axis. Because his indifference curves are strictly convex and the new bundle lies below and to the right of his old bundle, his MRSpb must be less than 4. That is to say, his indifference curve at the new point must be less steep than at the original bundle.

PE 80 i 100 – klasa materiału, określana przez współczynnik minimalnej wymaganej wytrzymałości (wsp. MRS). Zastosowanie materiału o wyższym MRS pozwala na zmniejszenie grubości ścianki rury przy zachowaniu określonej wytrzymałości na ciśnienie. Grubość ścianki rury decyduje o jej wytrzymałości na ciśnienie. Dla rur z tworzyw sztucznych używa się oznaczenia SDR (standard dimension ratio)

Podstawą wyboru wody gruntowej jako źródła ciepła, jest określenie, czy wydajność studni jest wystarczająca. Do stałej dyspozycji powinno być 205 l/h wody na kW mocy chłodniczej PC. Miejscowe zanieczyszczenia, poprzez swoje tamujące działanie, powodują częściowe zamarzanie wody. W ten sposób zmniejsza się prędkość strumienia, temperatura wody spada poniżej punktu zamarzania i tworzą się korki lodowe. Może to prowadzić do rozsadzenia wymiennika ciepła, co z kolei pociąga za sobą nieodwracalne uszkodzenia obiegu chłodzenia.

Consider Exhibit 5 , in which we observe an indifference curve for Smith and one for Warren. Suppose they are initially endowed with identical bundles, represented by a. They each have exactly identical quantities of bread and wine. Note, however, that because their indifference curves intersect at that point, their slopes are different. Warren’s indifference curve is steeper at point a than is Smith’s. This means that Warren’s MRSBW is greater than Smith’s MRSBW. That is to say, Warren is willing, at that point, to give up more wine for an additional slice of bread than Smith is. That also means that Smith is willing to give up more bread for an additional ounce of wine than Warren is.

We could say that Warren is better off by the value to him of one ounce of wine because he was willing to give up two ounces but only had to give up one ounce for his slice of bread. What about Smith? She is better off by the value to her of one slice of bread because she was willing to give up two slices of bread for her one additional ounce of wine but only had to give up one slice. Both Smith and Warren are better off after they trade. There is no more bread or wine than when they began, but there is greater wealth because both are better off than before they traded with each other. Both Smith and Warren ended on higher indifference curves than when they began.

Warren’s indifference curve is steeper at point a than is Smith’s. This means that Warren’s MRSBW is greater than Smith’s MRSBW. That is to say, Warren is willing, at that point, to give up more wine for an additional slice of bread than Smith is. That also means that Smith is willing to give up more bread for an additional ounce of wine than Warren is. Therefore, we observe that Warren has a relatively stronger preference for bread compared to Smith, and Smith has a relatively stronger preference for wine than Warren.

Active construction An active construction is a sentence in which the subject of the sentence is the person carrying out the action, or the event taking place (as opposed to a passive construction where the subject is the person affected by the action): mio marito fuma troppo ‘my husband smokes too much’; gli ospiti rimangono fino a sabato ‘the guests are staying until Saturday’. A verb can therefore have an active form (chiudiamo la porta a mezzanotte ‘we shut the door at midnight’) or a passive form (la porta viene chiusa a mezzanotte ‘the door is shut at midnight’).

Clause
#italian #italian-grammar
A clause is a section or part of a sentence that contains a subject and a verb. Complex sentences are made up of a series of clauses. The main clause (or clauses) is the part of a sentence that makes sense on its own and does not depend on any other element in the sentence. A subordinate clause always depends on another clause, and is often introduced by a conjunction such as che. There are different types of subordinate clause, for example: relative clauses, Ho visto il ragazzo che piace a mia sorella ‘I saw the boy that my sister likes’; or purpose clauses, Ha portato la macchina dal meccanico perché controllasse i freni ‘I took the car to the mechanic so that he could check the brakes’.
