Indifference Curve: The graph that shows the goods providing the same satisfaction level is known as the indifference curve. They are downward slopping curve and convex to the origin. The two indifference curve lines never intersects each other. Perfect Complement Goods: All those goods which are complement for each other that can be used only together. Example: car and petrol. Budget Line: It is defined as the combination of all the goods that a consumer can purchase, exhausting all his income. The formula for the budget line is: Here, is the quantity of good X. is the quantity of good Y. is the total income. is the price of good X. is the price of good Y. Substitution effects: It states that the demand of a good increases if the price of its substitute goods increase and vice versa. Take an example of tea and coffee, if prices of tea increase, then the demand for coffee increases. Income effects: It states that the demand for normal goods and the income are directly related which means that when income increases then the demand for normal goods also increases and vice versa.

Concept Introduction:

Indifference Curve: The graph that shows the goods providing the same satisfaction level is known as the indifference curve. They are downward slopping curve and convex to the origin. The two indifference curve lines never intersects each other.

Perfect Complement Goods: All those goods which are complement for each other that can be used only together. Example: car and petrol.

Budget Line: It is defined as the combination of all the goods that a consumer can purchase, exhausting all his income. The formula for the budget line is:

Here,

is the quantity of good X.

is the quantity of good Y.

is the total income.

is the price of good X.

is the price of good Y.

Substitution effects: It states that the demand of a good increases if the price of its substitute goods increase and vice versa. Take an example of tea and coffee, if prices of tea increase, then the demand for coffee increases.

Income effects: It states that the demand for normal goods and the income are directly related which means that when income increases then the demand for normal goods also increases and vice versa.

Problem 2. If the consumer preference can be represented by a CES function with δ = 0.5, i.e. u(x, y) = x0.5 + y0.5. Let the prices and income be (px, py, w). 1. Set up the Lagrangian expression.2. Take the first-order conditions.3. Substitute into budget constraint to derive the optimal consumption bundles.

1. A town relies on four different sources for its non-drinking water needs: dam water, reclaimed water, rain water, and desalinated water. The different sources carry different risks and costs. For instance, desalinated water is fully reliable due to abundant sea water, but it is more expensive than other options. Reclaimed water also has relatively lower risk than rain or dam water since a certain amount can be obtained, even during the dry. season, by the treatment of daily generated waste water. Using any of the four options requires an investment in that resource. The return on a particular water source is defined as the amount of water generated by the source per dollar of investment in it. The expected returns and standard deviations of those returns for the four water sources are described in the following table: Water resource Expected return St. Deviation Dam water 2.7481 0.2732 Reclaimed water 1.6005 0.0330 Rain water 0.5477 0.2865 Desalinated water 0.3277 0.0000 Higher…
