  So that is a very simple thing.
  这个其实不难
• 
  
  Suppose after finding the equilibrium I added a third
  假设平衡成立
• 
  
  asset that paid 1 dollar in period 2 next year.
  我加入第三份资产
• 
  
  Now, it would have a price of--added a third asset gamma,
  在第二阶段它回报了一美元
• 
  
  so pi_gamma--we'd have to solve for the
  πγ 表示它的价钱
• 
  
  equilibrium pi_gamma, and is there some word that I
  我们要在方程中解出 πγ
• 
  
  could use?
  有一些词语我可以用
• 
  
  So gamma is an asset that pays a dollar in period 2.
  在第二阶段它回报了一美元
• 
  
  It's like a bond promising a dollar in period two.
  就像债券一样在第二阶段利息是$1
• 
  
  The price of the bond would then have to be what?
  债券的价格之后会怎样呢
• 
  
  1 over (1 i) where i is called the nominal interest rate,
  1/(1+i) 表示名义利率
• 
  
  so we've got inflation is occurring in the model.
  通胀因素已经包括其中了
