Customers are located uniformly {spread out evenly on the beach] and do not like walking. The cost of walking every metre is the same {i.e. linear cost}. a] 1iiilhere will the ice cream stands be located in the Nash equilibrium lithe locations are chosen simultaneously? [iiir points] b] is the answer in {b} the best from society' s point of view? If not, what locationis] would be optimal? [1? points} c] Essay question {about zoo words] Critically discuss the following statement: "Rationality is never seen in real life, so we should not be assuming it in game theory.\" {You can use this game as an example. Do you think rms and customers would be rational?] {14 marks] 2} it is well known that the problem of negative oonsum ption extemaiities can be solved it the initial allocation of property rights is well established in law. For example, if it is the case that non-smokers are entitled to smoke-free air, then smokers have to compensate non-smokers for smoking. Similarly, if smokers are entitled to smoke, then non-smokers have to compensate smokers if they want them to smoke less. Please answer the following questions, keeping your answers concise! a} Consider now the case of a positive oonsumption extemality. Discuss howthis differs from the case of a negative extemaiity. Interpret the above arguments for the use of a positive externality, and discuss whether the arguments are still valid.

Assume that no technological progress and no population growth exist. a. What is steady-state? Because of an increase in acid rain, the rate of capital depreciation rises permanently. Given the saving rate, what are the effects on steady state capital per worker and output per worker? b. What is convergence? What prediction does the Solow growth model make about convergence? What does the empirical evidence say? Suppose every economy is in its steady state, then how could you explain the observed differences in per capita output among countries with the Solow model
