Consider two economies, labelled A and B. In each one, let every two- period-lived person be endowed with 20 units of the consumption when young and nothing when old. In Economy A, each young person chooses to consume 10 units of the consumption good. In Economy B, each young person chooses to consume 8 units of the consumption good. In each economy, the young person's choice is the one that maximizes lifetime welfare.
a. What, if anything, can you infer about the welfare level of the is one on an indifference curve representing greater welfare than
b. What, if anything can you infer about the welfare of the initial old current and future generations from this information? Specifically the other? from the description given for Economies A and B?
Ans. a) We can infer that the welfare level of current and future generations in economy A is high because each young person chooses to consume 10 units and it is the choice with maximises lifetime welfare. Economy A represents greater welfare.
b) The welfare of the initial old in economy A is high and Low in Economy B. This assumption is made on the basis of the question as it is mentioned that every two period lived person is endowed with 20 units when young and the choices they make when young are also given.
Do comment if you need further clarification .
Best of Luck !! !!
I need help with 1.2 and 1.4 Thank you 26 Chapter I. Trade without Money: The Role of Record Keeping 1.2. Suppose a person faces theollowing two bundles: Bundle A, which consists of 6 units consumption good when a person is young and 12 units of the consumption good of the of the consumption good when a person is young and 10 units of the consumption good when a person is old (Cl 4 and c2-: 10), which bundle would...
2.1. Consider an economy with a constant population of N 100. Each person is endowed with y-20 units of the consumption good when young and nothing when old. a. What is the equation for the feasible set of this economy? Portray the feasible set on a graph. With arbitrarily drawn indifference curves, illustrate the stationary combination of c1 and C2 that maximizes the utility of future generations b. Now look at a monetary equilibrium. Write down equations that represent the...

QUESTION-3: Suppose that L two period-lived individuals (1.2) (young, old) are born in period t and that 1: = (1+n)Le-1- Let utility be logarithmic: u(C1,0, C2,4+1) = In(1.c) + In(C2.6+1). Each individual born at timetis endowed with A units of the economy's single good. The good can be either consumed or stored. Each unit stored yields x>0 units of the good in the following period. Also that in the initial period, period t=0, in addition to the LO young individuals...
Problem 2. Consider an overlapping generations model with money, where t = 1,2,3,.... So, every period t, a generation of two-period lived agents are born. Their preferences are . They are endowed with ey units of the consumption good, when young, and e° units of the consumption good, when old. Assume that ey > eo > 0. The consumption good is perishable The initial old also have a quantity M of intrinsically valueless fiat money. Trading takes place as described...

10.1. Consider an economy in which there are 100 workers. One-half of the workers are endowed with 200 units of the consumption good when young and nothing when old. The remaining workers are endowed with 20 units of the consumption good when young and nothing when old. Each worker saves 30 percent of their endowment when young. Let the gross real return on capital be 1.25. Money supply grows according to following rule: Mt 1.1M._1. Assume that each worker uses...

C1 [19 marks] Suppose Malcolm and Barnaby are the only two people in a pure exchange economy. Food and clothing are the only two commodities. Malcolm is endowed with 30 units of food and 10 units of clothing, while Barnaby is endowed with 10 units of food and 30 units of clothing. Let F = units of food and C = units of clothing. Malcolm’s utility function is UM = 2 min(F, C) and Barnaby’s utility function is UB =...
