In: Economics
A) An individual's Marginal Rate of substitution is different at every point along his or her price consumption path.
B) Quasi-Linear utility, Cobb-Douglas utility, and perfect substitutes are each able to characterize an individual having interior and corner solutions for a positive level of consumption.
A) True
Reason: MRS = Slope of indifference curve and also
MRS = Px/Py
Along the price consumption path, as price of a good, say px changes, so will MRS
Thus, MRS is different at every point along the price consumption path
B) False
Reason: While substitutes have corner solutions, cobb douglas have interior solutions and not corner solution
