Question 1 :

Suppose country A and country B are deciding whether to install new incinerator to reduce regional air pollution or not. The new incinerators can reduce the domestic pollution and the cross-border pollution that affects both countries.

To quantify the analysis, suppose that if country A installs the new incinerator, it generates benefit of $1 million from reducing domestic pollution and of $1 million from reducing cross-border pollution. But, the benefit from reducing cross-border pollution will be equally shared by two countries. So, country A and country B will get a benefit of $0.5 million from reducing cross border pollution if country A installs the new incinerator.

The same calculation applies to country B. In other words, the new incinerator generates $1 million benefits domestically in B, and $1 million shared benefits to both A and B (each country gets $0.5 million)

a) Suppose that there is no cost in installing the new incinerator. Draw the game matrix and determine the equilibrium.

b) Suppose that the cost of installing the new incinerator is $2 million, draw the game matrix again. What is the implication from the equilibrium?

Suppose that the pharmaceutical rm Merck is deciding whether to develop a new diagnostic procedure that can detect early-stage Alzheimer's disease more accurately than existing tests. Developing this technology would require an up-front fixed cost FC > 0. If Merck develops the technology, it can screen Q patients for Alzheimer's at the variable cost VC(Q) = 20Q. Merck estimates that market demand for the procedure would be p(Q) = 80 - (1/10)Q a. Suppose that other companies can quickly copy...

Question 9 [10 marks / 10 minutes] Suppose there are two different mutant alleles of the same gene. Sequence analysis shows that both alleles are single nucleotide substitutions, and that different nucleotide positions within the gene are affected in each allele. Phenotypic analysis shows that one allele is a null allele, and the other is dominant negative (antimorphic). Explain what this information reveals about the two mutations. Give a hypothesis for how these two mutant alleles could show such markedly...
