In a market with Pd = 150 – 3 Qd and Ps = 50 + Qs , the government has regulated maximum of 20 units and is concerned if this move was maybe a little too harsh, especially if the deadweight loss to consumers (voters) is greater than the deadweight loss to producers

Consider a market served by 2 firms. Demand for their product is estimated to be P=100-Q, with Q=q1 + q2. Assume that production costs are symmetric and given by C=10q.


(i) Assume that firm 1 was given the opportunity to commit its output level before firm 2 chooses its quantity. Show that firm 1 has indeed incentive to become a market leader by setting its quantity first.


(ii) Is there an incentive for the two firms to merge? Explain your answer clearly.

What will be the elasticity of substitution of production function q=√L+K ?

Given α is non-income tax, β is income tax, δ is marginal propensity to consume, γ is autonomous consumption, T (tax), Y (national income), I0 (investment) and G0 (government expenditure).


a) Formulate the equations needed to find the reduced form of equilibrium income (Ye).

A firm’s output is K(100 − K). The price of the product is 1 per

unit. The capital provider charge a rent of r per unit of capital, K, where

r is between 0 and 100. The firm either accepts or rejects the offer. If the firm

accepts the offer, it chooses the amount K of capital (which you should take to

be a continuous variable, not an integer); if it rejects the offer, no production

takes place (K = 0). The firm’s preferences are represented by its profit; the

capital provider’s preferences are represented by the value of rK.

(i) Formulate situation as a sequential game. (what are the players? which

one is first mover? what are the strategies and payoff functions?)

(ii) Find subgame perfect equilibrium of the game.

(iii) Is there a (K, r) which will generate a higher total pay-off (sum of firm and

capital provider’s pay-offs) than the total pay-off at the SPE.

(iv) Find Nash equilibrium for which the outcome differs from any subgame perfect equilibrium outcome.

Ball thrown vertically from 12 m level in elevator
shaft with initial velocity of 18 m/s. At same
instant, open-platform elevator passes 5 m level
moving upward at 2 m/s.
Determine (a) when and where ball hits elevator and
(b) relative velocity of ball and elevator at contact.
