Demand
1. One of the most important building blocks of economic analysis is the concept of demand. When economists refer to demand, they usually have in mind not just a single quantity demanded, but what is called a demand curve. A demand curve traces the quantity of a good or service that is demanded at successively different prices.
2. The most famous law in economics, and the one that economists are most sure of, is the law of demand. On this law is built almost the whole edifice of economics. The law of demand states that when the price of a good rises, the amount demanded falls, and when the price falls, the amount demanded rises.
3. It is not just price that affects the quantity demanded. Income affects it too. As real income rises, people buy more of some goods (which economists call normal goods) and less of what are called inferior goods. Urban mass transit and railroad transportation are classic examples of inferior goods. That is why the usage of both of these modes of travel declined so dramatically as postwar incomes were rising and more people could afford automobiles.

The Business of Weddings
1. Though the odds may be barely in their favor, every couple who goes to the altar believes that they will make that trip only once in their lives. They want the day to be perfect, and they are asking for much more than good weather. They want the most beautiful clothes, the freshest flowers, the prettiest music, and the best food. No one, especially not the bride — nor her family who will foot the bill — is in any mood to economize.
2. A quick look at any bride magazine will reveal that plenty of attractive goods and services compete for a share of the wedding budget. Beside the obvious choices of rings, dresses, flowers, and photographs, there are the less apparent expenses: a lavish cake, a rehearsal dinner, a reception, music for both the ceremony and the reception, tips, and even napkins and matchbooks printed with the couple's names and the wedding date.
3. As the arrangements are generally complicated, there are plenty of services that can be hired to help with the planning and execution of the ceremony. There is also an amazing amount of free advice covering every aspect of the wedding: planning the photographs, selecting the wedding rings, choosing the flowers, picking the honeymoon spot, and so on. One magazine lists over 350 such pamphlets, published of course by businesses who have something to offer. Considering that weddings do more than 12 billion dollars worth of business annually in the U.S. alone, such activity isn't surprising.
4. What is surprising, is that no one company dominates the industry. It seems that when people plan for a day as special to them as a wedding, they resist standardization. They turn instead to the small local suppliers known to them or to their friends. Family members or friends often serve as photographers, caterers and musicians. This not only helps bring the wedding cost down, it makes it more personal. What about the couple that doesn't want to take part in this billion dollar industry? They can go to city hall and get married for less than the price of a hamburger.

Insurance
1. Insurance plays a central role in the functioning of modern economies. Life insurance offers protection against the economic impact of an untimely death; health insurance covers the sometimes extraordinary costs of medical care; and bank deposits are insured by the federal government. In each case a small premium is paid by the insured to receive benefits should an unlikely but high-cost event occur.
2. An understanding of insurance must begin with the concept of risk, or the variation in possible outcomes of a situation. A shipment of goods to Europe might arrive safely or might be lost in transit. A person may incur zero medical expenses in a good year, but if he is struck by a car, they could be upward of $100,000.
3. We cannot eliminate risk from life, even at extraordinary expense. Paying extra for double-hulled tankers still leaves oil spills possible. The only way to eliminate auto-related injuries is to eliminate automobiles. Thus, the effective response to risk combines two elements: efforts or expenditures to lessen the risk, and the purchase of insurance against the risk that remains.

World Bank
1. World Bank or International Bank for Reconstruction and Development is a multinational institution set up in 1947 to provide economic aid to member countries - mainly developing countries – to strengthen their economics. The Bank has supported a wide range of long-term investments including infrastructure projects such as roads, telecommunications and electricity supply; agriculture and industrial projects including the establishment of new industries, as well as social, training and educational programmes.
2. The Bank's funds come largely from the developed countries, but it also raises money on international capital markets. The Bank operates according to 'business principles' lending at commercial rates of interest only to those governments it feels are capable of servicing and repaying their debts.
3. In 1960, however, it established an affiliate agency, the International Development Association, to provide low-interest loans to its poorer members. Another affiliate of the World Bank is the International Finance Corporation which can invest directly in companies by acquiring shares.
