Question:

Consider J=J1+J2 polluting firms, where there are J1 firms of type 1 and J2 firms of type 2. The abatement cost functions are given by Cj(ej)=(aj−bjej)2/2bfor types j=1,2. The damage function is D(E)=dE2/2, where E is total emissions.

(a) Determine the socially optimal allocation of emissions.

(b) Assume now that there are transaction costs Tj(tj)=φttj, where tj=|ej−ēj|. Assume that the regulator has issued a total number of permits that is socially optimal. Type 1 firms (type 2 firms) have an initial endowment smaller (larger) than socially optimal. Determine the trade equilibrium and calculate the welfare loss generated through transaction costs.

(c) Repeat part (a) for: image text in transcribed
