Q4 how do we find d competitive eqm ?http://economicsentrance.weebly.com/uploads/1/1/0/5/1105777/26_jun_2004_option_a.pdf
won't it be px = py so dd becomes x= m/2px y = m / 2px so m1= m2 = 1000 so they consume 500 , 500 . whats wrong here ?? |

Hi Maahi.. :)
You've found just one of the competitive equilibirum allocation. There are others competitive eqm allocation. Demand for Agent 1: x1=y1= 1000px/px+py Demand for Agent2: x2=y2= 1000py/px+py For market clearing: It should be the case that x1+x2=1000 and y1+y2=1000. And you can check the market clears for all postive price ratio. Hence, the corresponding competive equilibirum allocations would be where x1=y1 and x1∈ [0,1000]. (45 degree line constitutes the Set of Competitive equilibirum allocation)

Hi Duck,
Could you plz tell the right approach to get competitive equilibrium prices in q-6????..Is it can be done by hit and try only??? My approach Agent-1 Demand for x1=999px/px+py Agent-2 demand for x2=1000py/px+py Now,For competitive equilibrium, Total demand for commodity x must equal to total supply. ==>[999px/px+py]+[1000py/px+py]=999. Now, In this case as I put px=1 & Py=0...above equality satisfy. At this price competitive equilibrium: x1=999 and y1 belong [999,1000].

Q10) You must have done some calculation error.
Profits = (1-(3-4c/6)-(c/3))(3-4c/6) - c(3-4c/6) - (9c^2-13c/18) Maximise it wrt c. Q30) P(X<-1) = P(X>1) = p Now, P(X^2 > 1) = P( 1<X<-1) = 2p P(Y^3 > 1) = P(Y>1) = p [As X and Y are independent random variables with standard Normal Distribution] Therefore, P(X^2>1 & Y^3>1) = P(X^2>1) * P(Y^3>1) [ As independent] = 2p*p = 2(p^2)

Hi Sumit.. :)
No Hit and trial. Your approach is correct. You must also check whether the market for Good y clears or not. Another way: Plot the edgeworth and check for competitive equilibrium allocations.

For Competitive equilibirum, we need to check two conditions:
(i) Given prices, Agents maximize their utility i.e find demand. (ii) Market clears for all goods. Now, whether goods are perfect substitutes, perfect complements or whatever, use the above way.

ok suppose there is a min fn and price of one good is zero as its in excess . so how do we check here

So just find the demand at zero price and then check whether the market is clearing or not.. :)
