latex error! exitcode was 2 (signal 0), transscript follows:

latex error! exitcode was 2 (signal 0), transscript follows:

  1. [JR 2.23] Consider the utility function,

    latex error! exitcode was 2 (signal 0), transscript follows:
    
    
    1. What restrictions must be placed on parameters, a, b, and c for this function to display risk aversion?

    2. Over what domain of wealth can a quadratic VNM utility function be defined?
    3. Given the gamble

      latex error! exitcode was 2 (signal 0), transscript follows:
      
      

      show that

      latex error! exitcode was 2 (signal 0), transscript follows:
      
      
      and that
      latex error! exitcode was 2 (signal 0), transscript follows:
      
      
      .
    4. Show that this function, satisfying the restrictions in part (a), cannot represent preferences that display decreasing absolute risk aversion.

  2. Provide a proof that the CES utility function

    latex error! exitcode was 2 (signal 0), transscript follows:
    
    

    actually exhibits constant elasticity of substitution and thus deserves its name.

  3. [JR p.125] Consider the production function

    latex error! exitcode was 2 (signal 0), transscript follows:
    
    
    1. Show that this function exhibts variable returns to scale;

    2. Find the output level

      latex error! exitcode was 2 (signal 0), transscript follows:
      
      
      for which this function exhibits constant returns to scale.
