Explanation of Solution

When the marginal external cost (MEC) is zero, the marginal social cost (MSC) is equal to the marginal private cost (MPC). On the other hand, when the marginal external benefit (MEB) is zero, the marginal social benefit (MSB) is equal to the marginal private benefit (MPB)

Economics Concept Introduction

Marginal social benefit (MSB): Marginal social benefit (MSB) is a high utility or satisfaction felt by an individual when they purchase an additional unit of a good or service.

Marginal social cost (MSC): Marginal social cost is the added cost spent for producing an extra output of a unit.

Marginal external benefit (MEB): The marginal external benefit refers to the amount of additional benefits obtained in the process of increasing one more unit of output to third party.

Marginal external cost (MEC): The marginal external cost refers to the amount of additional cost obtained in the process of increasing one more unit of output to third party.

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…
