The changes in revenue with a change in the price of cigarettes Introduction: Price Elasticity of Demand – If for a one unit change in the price, the demand increases more than proportionately the demand is said to be elastic. If however, the responsive change in demand is less than proportionate the demand is said to be inelastic while it is said to be unit elasticity if the percentage change in demand is equal to the percentage change in price. If elasticity is ‘e’ then it is defined as: e = %Δ Q %Δ P If e > 1, the demand is elastic e < 1, the demand is inelastic e = 1, the demand is unit elastic e →∞, the demand is perfectly elastic e = 0, the demand is perfectly inelastic Total Revenue - It is the total earnings of the producer/seller by selling Q units of output each at a price of P. Functionally, it is written as: T R = Q X P

To determine

The changes in revenue with a change in the price of cigarettes

Introduction:

Price Elasticity of Demand – If for a one unit change in the price, the demand increases more than proportionately the demand is said to be elastic. If however, the responsive change in demand is less than proportionate the demand is said to be inelastic while it is said to be unit elasticity if the percentage change in demand is equal to the percentage change in price. If elasticity is ‘e’ then it is defined as:

e=%ΔQ%ΔP

If e > 1, the demand is elastic

e < 1, the demand is inelastic

e = 1, the demand is unit elastic

e →∞, the demand is perfectly elastic

e = 0, the demand is perfectly inelastic

Total Revenue- It is the total earnings of the producer/seller by selling Q units of output each at a price of P. Functionally, it is written as:

TR=QXP

Consider the simple discrete job search model that we studied in class. Only the unemployed can receive one offer per period from F(w) that is a uniform distribution on [0,2]. There is a constant probability of being laid off at the end of each period while employed. Assume that she can get a new offer right away when laid off. We want to understand the reservation wage, WR, in this model. Assume that u(c) = c. The parameters are a discount factor ẞ and an unemployment benefit b.R and show that T is contraction on [0, ∞). Explicitly state any additional assumptions that you may need.(Grading guide line: 5pt for the exact form of T, 10pt for showing contraction, and 5pt for stating correct assumptions.)< (b) Discuss why (a) is useful to understand the reservation wage wд in this economy.< (c) We write WR = WR (b,ẞ,λ) to reveal its dependence on (b,ẞ,λ).

3. Consider the market for paper. The process of producing paper creates pollution. Assume that the marginal damage function for pollution is given by: MDF = 3E where damages are measured in dollars and E is the level of emissions. Assume further that the function describing the marginal abatement cost of emissions is given by MAC 120-E where benefits are measured in dollars and E is the level of emissions. a. Graph the marginal damage function (MDF) and the marginal abatement cost function (MAC). b. What is the unregulated level of emissions Eu? What is the social welfare of this emissions level? c. Assume an existing emission quota limits emissions to E = 60. Show on the graph why this policy is inefficient. What is the deadweight loss caused by this policy?
