Cardinal Utility versus Ordinal Utility
Cardinal numbers versus ordinal numbers Cardinal numbers are quantities, e.g., one, two , three, etc. Ordinal numbers are rankings, e.g., rst, second, third, etc. Are the following cardinal or ordinal? page number t
Utility Maximization
Budget Constraint
Let px = price of good x; py = price of good y; and I = income. The budget constraint is given by px x + py y = I: What is the shape of the budget constraint? What is the slope of the budget constraint? What will be
Applications of Indierence Curve Analysis
1. Labor Supply
A consumer has the utility function U (x; `), where x = quantity of good x; and ` = amount of leisure (measured in hours). Suppose T = h + `; where T is the total number of hours available and h is
Demand Curves
x = d(px ; py ; I ) y = d(px ; py ; I ) From commodity space (x and y ) to price-quantity space (px and x). The determinants of the demand of x are px ; py ; and I: Demand curves have the following properties.
1. Homogeneity
