Thomas Malthus wrote that if wages exceeded subsistence levels the population would​ increase, which, in turn would drive real wages back down to subsistence. Suppose there were an increase in the demand for​ labor, which raised real wages. Under​ Malthus's theory, the supply curve for labor would shift. Use the line drawing tool to draw and label a new labor supply curve.

*parallel and under labor supply line*

The graph shows the initial aggregate demand ​(AD1​) and​ short-run aggregate supply ​(AS1​) curves for an economy. The initial equilibrium is point​ E, the point of intersection of the AD1 and AS1 curves. The economy is experiencing a negative supply shock such as an increase in the price of oil. ​1.) Using the line drawing tool​, draw a new aggregate demand or aggregate supply line. Label the curve appropriately. ​2.) Using the point drawing tool​, locate the new equilibrium point to indicate the effects of a negative supply shock on​ short-run output and the price level.

B

Many economists believe countries that open themselves to foreign investment of plant and equipment will benefit in terms of increased technological change because local companies will learn from the foreign companies. In the last several​ decades, China has been more open to foreign investment than India. This is consistent with the two​ countries' patterns of economic growth because

China's growth in GDP was much higher than​ India's growth in GDP.

Some critics of cultural theories of economic growth note that some societies can suddenly start to grow very rapidly with no obvious accompanying cultural changes. How well does Professor Gregory​ Clark's theory fit the rapid growth in some East Asian economies in recent​ years?

Clark's theory fits well with the rapid growth in East Asian economies since western values have become more acceptable.

Employees will become more productive and the firm will hire more employees until marginal benefit equals marginal cost.

From 1960 until​ 2006, Singapore's capital stock grew​ rapidly, averaging almost 10 percent per year. This growth of​ Singapore's capital stock will shift the production function _____.

upward; greater than

Which of the following will promote economic growth through capital​ deepening?

Suppose that a group of consumer activists claims that drug companies earn excessive profits because of the patents they have on drugs. The activists advocate cutting the length of time that a drug company can hold a patent to five years. They argue that this will lead to lower prices for drugs because competitors will enter the market after the​ five-year period. Do you see any drawbacks to this​ proposal?

It will reduce the incentive for drug companies to invent new drugs.

increase the marginal benefit from employing labor and therefore increase the demand for labor and real wages.

left

In​ 2014, China decided to cut back on its economic growth in order to prevent imbalances from occurring in their economy. With slower economic growth in​ China, there is

less opportunity for exports to​ China, so aggregate demand in the rest of the world will decline.

When the labor market is in​ equilibrium, the labor demand and supply curves determine the

level of employment in the economy and the level of real wages.

When wages rise and the​ short-run aggregate supply curve shifts​ up, the result is​ "cost-push" inflation.

rise

Suppose that technology​ improves: for any level of the capital​ stock, the​ short-run production function shifts up. Potential output will ____.

rise

Top athletes or entertainers would be more likely to change countries to reduce their taxes as compared to ordinary​ middle-class workers because

these individuals can realize more tax savings than ordinary​ middle-class workers who have lower incomes.

Soft drink companies spend a considerable amount of money on marketing. These expenditures could be considered a form of capital because

this intangible capital is an important source of economic growth.

In an economy with no government sector or foreign​ sector, saving must equal investment because

total income is equal to consumption and saving; total income is equal to total demand; total demand is equal to consumption and investment

In professional​ football, salaries are determined by the league for the first several​ years, but then the athletes have a chance to become free agents and seek employment with other teams. When they are under​ contract, the athletes have

sticky wages but they become flexible when they become free agents.

Convergence is the process by which poorer countries close the gap with richer countries in terms of real GDP per capita. Suppose the line in the figure at right pointed up and to the right. That would tell us

that there is less of a tendency for convergence.

The workers in​ _________ take the least vacation​ time, on average.

the United States

Per-capita output is higher in the United States than in Germany and yet output per worker is higher in Germany. According to recent​ studies, the main cause for this is the difference in

the amount of labor their workers supply to the market.

In the long​ run, if aggregate demand decreases​,

the price level will decrease and output or real GDP will remain unchanged.

Labor market equilibrium occurs at a real wage at which the quantity demanded for labor equals

the quantity supplied of labor.

Suppose a health worker visited one village and personally gave residents sweets in order to take vaccinations. In this​ village, vaccination rates increased. Is this strong evidence that giving sweets would increase vaccination​ rates?

​No, because the worker only visited one village and it was not a controlled experiment.

Suppose gasoline prices increased sharply and consumers became fearful of owning too many expensive cars. As a​ consequence, they cut back on their purchases of new cars and decided to increase their savings. Assuming a​ short-run aggregate supply​ curve, this behavior shifts the aggregate demand curve to the
