During the $1990$s, General Electric put together a long string of consecutive quarters in which the firm managed to meet or beat the earnings forecasts of Wall Street stock analysts. Some skeptics wondered if GE “managed" earnings to meet Wall Street's expectations, meaning that GE used accounting gimmicks to conceal the true volatility in its business. How do you think GE's long run of meeting or beating earnings forecasts affected its cost of capital? If investors learn that GE's performance was achieved largely through accounting gimmicks, how do you think they would respond?

How did the creation of the Fed improve our banking system?

Understanding the evolution of our banking system is important because it helps us understand the features of modern banking. Today we have a managed money supply that is accepted by everyone simply because people have faith in it. Which of the following is true about our banking system today?

a) Most of our money circulates as coins and paper currency.

In many of the world’s poorest countries, nearly 50 percent of the population is under 15 years of age. If these people are to help improve the productivity of their economies, they must be trained in modern methods of production. In 2000, just over 4 million of the 8.8 million people of Chad were under 15. Explain why it would be difficult for many of these children to be educated and become productive members of a growing economy.

Are the marks one receives in a course related to the amount of time spent studying the subject? To investigate this mysterious possibility, a student took a random sample of 10 students who had enrolled in an accounting class last semester. He asked each to report his or her mark in the course and the total number of hours spent studying accounting. These data are listed here: Study

$$\begin{array}{rllllllllll}\text { time } & 40 & 42 & 37 & 47 & 25 & 44 & 41 & 48 & 35 & 28 \\ \text { Marks } & 77 & 63 & 79 & 86 & 51 & 78 & 83 & 90 & 65 & 47\end{array}$$

By the time she was awarded the Nobel Prize in $1991$, she har already been under house arrest for two years.

Palm oil is one of the world's most versatile raw materials. It is estimated that it is an ingredient in $50 \%$ of all products sold by a typical supermarket. It is used in a wide range of products from margarine, cereals, crisps, sweets and baked goods to soaps, washing powders and cosmetics but it is often listed as just 'vegetable oil'. So, its production benefits customers of these products. In addition, an estimated $1.5$ million small farmers grow the crop in Indonesia, along with about $500000$ people directly employed in the sector in Malaysia, plus those connected with related industries. The governments of these countries have encouraged production as it is a major export for these economies.

However, the industry has a poor image. Palm oil production has led to deforestation with a resulting negative impact on climate change. There has been substantial loss of wildlife habitat, even endangering the orangutan. Palm oil companies have been accused by community groups of driving native people off their land which is then used for palm oil production. Socially responsible businesses, such as KL Kepong in Malaysia, have agreed to an ethical code which aims to make palm oil production 'sustainable' with fair treatment for all local populations affected by it. However, many companies have been accused of breaking the code as there is no strong world body to stop them behaving irresponsibly. In any case, food manufacturers want to maximise profits and final consumers want the cheapest raw materials possible.

Analyse the impact on these two stakeholder groups of a decision by KL Kepong to close one of its palm oil plantations

Listed below are nine technical accounting terms:

$$\begin{array}{lll}\text { Variable costs } & \text { Relevant range } & \text { Contribution margin } \\ \text { Break-even point } & \text { Fixed costs } & \text { Semivariable costs } \\ \text { Economies of scale } & \text { Sales mix } & \text { Unit contribution margin }\end{array}$$

Each of the following statements may (or may not) describe one of these technical terms. For each statement, indicate the accounting term described, or answer "None" if the statement does not correctly describe any of the terms.

e. Unit sales price minus variable cost per unit.

Modern halogen lightbulbs allow their filaments to operate at a higher temperature than the filaments in standard incandescent bulbs. For comparison, the filament in a standard lightbulb operates at about $2900 \mathrm{~K}$, whereas the filament in a halogen bulb may operate at $3400 \mathrm{~K}$. The human eye is most sensitive to a frequency around $5.5 \times 10^{14} \mathrm{~Hz}$. Which bulb produces a peak frequency closer to this value?
