1. Please express the model of natural rate of unemployment according to blanchards book and then give your comments 2. How can you explain the aggregate demand and aggregate supply curves. How they are different from the usual definition on demand and supply curves

Multiple Choice 1. Equilibrium a. is a concept unique to economics. b. always occurs where supply equals demand. C. results when opposing forces fail to cancel each other out. d. indicates balance. e. all of the above

1. The equilibrium price of a good is determined by the intersection of its supply and demand curves. We can know everything about a goods cost of production( that, is we can know its supply exactly) yet still not know where the demand curve will intersect the supply curve

Multiple Choice If one person can perform a task in fewer hours than another, you know the person has in performing the task. a. an absolute advantage. b. a comparative advantage. C. both a comparative advantage and an absolute advantage. rd. neither an absolute nor a comparativ advantage

This chapter introduces comparative advantage and shows that having people specialize in the production in which they are relatively more efficient allows the production of more of everything. It introduces the production possibilities curve and develops the production possibilities model to show precisely how specialization enhances the productive capacity of an economy
