Suppose that Tom considers 12.3 units of good x to be a perfect complement for 17.86 units of good y. Write down a utility function that represents Tom’s preferences. What is the slope of the Tom’s income expansion path?

Solutions

Expert Solution

U(x, y) = min{17.86x, 12.3y}

For such functions, 17.86x = 12.3y (As they are always consumed together.)
So, y = (17.86/12.3)x

Slope of income expansion path = dy/dx = 17.86/12.3 = 1.45

An agent considers good 1 and good 2 "perfect substitutes" and thus her preferences can be represented by the utility function u (x,y) = 4x + 2 y. The agent starts with $10. Use this information to answer the following questions. (a) What is the slope of this agents indifference curves (i.e. the mrs)? Hint: You do not need to use calculus if you solve for the equation of an indifference in slope-intercept form. (b) What is the maximum price at which...

Suppose that Jim uses his budget to purchase 100 units of Good X and 100 units of Good Y. When the price of Good X rises, he purchases 55 units of Good X and 95 units of Good Y. An economist calculates his compensated budget and finds that in that scenario, Jim would buy 60 units of Good X and 105 units of Good Y. Calculate the substitution effect. (Remember to include a negative sign (-) if the effect reduces...
