shift the curve up

Exchange Rates and Comparative Advantage

- The U.S. comparative advantage in innovation results in higher wages in the U.S. -As industries mature, they move to low-wage areas -In order to regain our comparative advantage, the U.S. wage premium will have to decline. The U.S. exchange rate will likely decline or there will be large increases in foreign wages-or both. -Exports will then be cheaper for foreigners and foreign products imported will be more expensive.

Summery

- The production possibility curve illustrates maximum outputs from a given number of inputs -To get increasing amounts of something, we must give up ever-increasing quantities of something else - Trade allows people to use their comparative advantage and shift out society's PPC -Efficient, inefficient, and unattainable points on the PPC - Through specialization and trade, countries can increase consumption - If the U.S. can maintain its strong comparative advantage using new technologies and innovation, lost jobs can be replaced with other high-paying jobs - Because many goods are cheaper to produce in foreign countries, production that formerly took place in the U.S. now takes place in foreign countries - Globalization is the increasing integration of economies, cultures, and institutions across the world - Production shifts to countries where it is cheapest to produce is guided by the law of one price

Distribution and Productive Efficiency

- The productive possibility curve focuses on efficiency and ignores distribution -If a method of production will change income distribution we cannot determine if that method is efficient or not (Efficiency has meaning when analyzing a particular goal) -In our society, most people prefer more to less, and many policies have relatively small distribution effects

A downward-sloping line that makes a 45 degree angle with the horizontal and vertical axes has a slope of

-1

given a production possibility curve good X (on the x-axis) and good Y (on the y-axis), the opportunity costs of increasing good X is greatest when the slope of the production possibility curve is

-6

Trade and Comparative Advantage

-The PPC is bowed outward because individuals specialize in the production of goods for which they have a comparative advantage -For a society to produce on its PPC, individuals must produce those goods for which they have a comparative advantage and trade for other goods -According to Adam Smith, humankind's proclivity to trade leads to individuals using their comparative advantage

Application: U.S. Textile Production and Trade

-Two hundred years ago, the U.S. had a comparative advantage in textile production -Now, countries with cheaper labor, such as Bangladesh, have the comparative advantage in textiles -The gains from trade are higher wages for Bangladesh workers and lower-priced cloth for U.S. consumers

The Benefits from Trade

-When people freely enter into trade, both parties can be expected to benefit from trade -Without trade, each country can only consume those combinations of goods along their PPCs -If each country specializes according to comparative advantage and trades, they can consume beyond their "no-trade" PPCs

What is 25 percent of 400?

production possibility curve (PPC)

A line which shows the different combinations of two goods an economy can produce if all resources are used up.A curve meaning the combination of outputs that can be obtained from a given number of inputs -It gives you a visual picture of the trade-off embodied in a decision -created from a production possibility table by mapping the table in a two-dimensional graph - Demonstrates that there is a limit to what you can achieve, given existing institutions, resources, and technology and that every choice you make has an opportunity cost

comparative advantage

A resource if it is better suited to the production of one good than to the production of another good. The ability to be better suited to the production of one good than to the other production of another good -The reason we must give up more and more butter as we produce more guns is that some resources are relatively better suited to producing guns, while others are relatively better suited to producing butter

John can clean the house in three hours and do the laundry in four. Jane can clean the house in two hours or do the laundry in two. Can they benefit by specialization and trade?

If the principle of increasing marginal opportunity cost holds, the opportunity cost of producing each additional unit of a good should fall as production of that good rises. True or false?

False

The law of one price means that the price eventually will be the same in all countries and eventually countries will not have a reason to trade. True or false?

False

False

Investment in capital goods is one way to increase the standard of living in the future. Investment in capital goods, however, means that we must forgo consumption today. One of the trade-offs facing an economy is consumption today and consumption in the future. The following table presents such a trade-off. With this information we know that the opportunity cost of which of the following is the greatest? Current consumption: 800 750 650 600 550 Future consumption: 100 260 340 380 400

Increasing current consumption from 750 to 800

In the graph, what change would increase production efficiency?

Moving from C to A

In election campaigns, presidents often promise more of everything (that is, more guns and butter). What would help those elected presidents fulfill that promise?

The economy becomes more efficient

Globalization

The increasing integration of economies, cultures, and institutions across the world -2 effects on firms: A positive effect: globalization provides larger markets than the domestic economy A negative effect: the global economy increases the number of competitors for the firm

Increasing Opportunity Costs of the Trade-off

The principle of increasing marginal opportunity cost tells us that opportunity costs increase the more you concentrate on the activity - Slope is flat at A: This means there is a low opportunity cost to produce more guns - Slope is steep at: This means there is a high opportunity cost to produce more guns

An inverse relationship occurs between two variables when as one goes

up the other goes down

The Law of One Price

wages of workers in one country will not differ significantly from the wages of (equal) workers in another institutionally similar country -If the U.S. loses its comparative advantage based on technology and institutional structure, U.S. wages will decrease relative to wages in many other countries -The reality is that the U.S. has been living better than it could have otherwise precisely because of trade.
