1)A) market demand Curve for private good is Horizontal Summation of individual demand functions
X = 10-P + 10-P
X = XA + XB
X = 20-2P
b) at eqm, P = MC = 2
X = 20-2*2 = 16
C) XA = 10-2 = 8
XB = 10-2 = 8
mandatorarily Answering only first question
1. Individual A and B have the following marginal benefits for private good X: MBA =...
Consider the market for a Hepatitis A vaccine. The market demand or private marginal benefit schedule is given by P = 80 – 0.25Qd, where Qd is the number of vaccines demanded per month and P is the price per vaccination. The market supply for the vaccine is (Private marginal cost schedule) is P = 15 + 0.4Qs, where Qs is the number of vaccines supplied per month. a. Draw a graph of the market and solve the number of...
Consider a hypothetical market for the hepatitis A vaccine. The market demand (or private marginal benefit schedule) is given as: P = 80 -0.25Qd where Qd denotes the number of vaccinations demanded per month and P is the price per vaccination. The market supply for the vaccine (the private marginal cost schedule) is: P = 15 + 0.4Qs where Qs denotes the number of vaccinations supplied per month. a. Sketch a graph of the market and solve for the number...
A market supply curve reflects the external benefits of producing a good or service. marginal private coats of producing a good or service. marginal social costs of producing a good or service. external costs of producing a good or service.
Suppose the demand (i.e. the private marginal benefit) for industrial grade stink bombs is given by P=300-2Q and supply (i.e. the private marginal cost) for is given by P=Q. Also, suppose that the marginal external damage of consuming this product is $60 per stink bomb. a. What is the equilibrium quantity of stink bombs sold and consumed? b. What is the socially optimal equilibrium quantity of stink bombs sold and consumed? c. Considering your answers to (a) and (b), are...
Description of the economy: For each of the following problems, consider a 2x2 Exchange Economy with two consumers A and B, and two goods X and Y . The preferences of consumer A can be represented by the utility function uA(xA, yA) = xAyA , where xA is the amount of good A consumed by consumer A, and yA is the amount of good Y consumed by consumer A. The preferences of consumer B can be represented by the utility...

A certain production process generates both external costs and external benefits. The marginal private cost (NPC/and marginal external cost (MEC) functions are Increasing. while the marginal private benefit (MPB and marginal external benefit (MEBlfunctions are decreasing. The socially optimal (SO) as well as the individually rational (IR) output level are given by positive and finite numbers. When will the IR output level be higher than the SO one? provided that MEC SO-MEB SO b) provided that MEC SO MEB so...

We are considering a market with marginal cost of P=100+2Q and a demand of P=500-2Q. Use that information to answer the following questions. a. Find the market equilibrium (price and quantity in the market). b. Find producer and consumer surplus. c. Now imagine production of this good created a negative externality of 1$ per unit of output. Find the socially optimal outcome (price and quantity) taking this externality into account. d. Find consumer and producer surplus at the socially efficient...
