Consider an exchange economy with two consumers: Charlotte and Dylan, and two goods: quinoa (Q) and raspberries (R). Charlotte has an initial endowment of 99.6
Consider an exchange economy with two consumers: Charlotte and Dylan, and two goods: quinoa (Q) and raspberries (R). Charlotte has an initial endowment of 99.6 units of quinoa and 76 raspberries. Dylan has 124.4 units of quinoa and 78.1 raspberries.
Charlotte's utility function is given byUC=QC1/2RC1/2, whereQCandRCare her consumption of Q and R, respectively. Dylan's utility function is given byUD=QD1/3RD2/3, whereQDandRDare his consumption of Q and R, respectively.
Suppose that the market price of quinoa ispQ=2and the market price of raspberries ispR=1.
- Keeping the price of raspberries normalized atpR=1, find themarket clearingprice of quinoa,pQ. (Hint: write the value of the initial endowment for each consumer as a function ofpQ. Then, using the utility maximizing condition along with the budget constraint, find the optimal choice ofQfor each consumer as a function ofpQ. Finally, use the market clearing condition, which states that the total consumption ofQmust be equal to the total endowment ofQin the economy, to solve forpQ. Keep your numbers as precise as possible at all stages of the calculation, and only round your final solution to the second decimal point.)
