Home's demand curve for wheat is upper p equals 10 minus startfraction 1 over 20 endfraction upper q subscript upper d . its supply curve is upper p equals 4 plus startfraction 1 over 20 endfraction upper q subscript upper s . home's quantity demanded of wheat is upper q subscript upper d baseline equals 200 200 - 20 20p. home's quantity supplied of wheat is upper q subscript upper d baseline equals 80 80 + 20 20p. home's import demand schedule is upper m equals upper q subscript upper d baseline minus upper q subscript upper s baseline equals 120 120 - 40 40p or p = 3 3 - 1/40 startfraction 1 over 40 endfraction upper q subscript upper m. the home price of wheat in the abscence of trade would be upper p superscript upper a baseline equals 60 60.

a)P=2

(b) P*=1

c)Volume of trade(Q) = 20

d) IM(1.75) = XS∗(1.25) = 10

e) 2.5

Step-by-step explanation:

a) Home’s demand curve for wheat is

D = 100 − 20P.

supply curve is

S = 20 + 20P.

Import demand IM(P) = D(P) −S(P) = 80 − 40P.

Absence of trade is equivalent to import demand being zero.

80 − 40P=0

P=2

(b) Foreign demand curve:

D* = 80 − 20P,

Supply curve

S* = 40 + 20P.

Foreign’s export supply curve is given by: Xf:

Xf(P) = S*(P)-D*(P)

Xf(P) =−40 + 40P.

The absence of trade means export supply being zero:

=−40 + 40P=0

P*=1

c) At equilibrium, import demand equal to export supply giving:

80 − 40P = -40+40P

At equilibrium in free trade:

World price(w)=P

Solving for w:

w = 1.5

Volume of trade(Q) = 20

d) The tariff creates a wedge between prices between the two countries, so we now have

P = P*+0.5

Setting export supply equal to import demand, we get:

80 − 40(P* + 0.5) = −40 + 40P*

P *= 1.25

P = 1.75.

At these prices production in each country is given by the following:

The volume of trade is given by:

IM(1.75) = XS∗(1.25) = 10

(e) The home import competing producers are better off after the imposition of tariff because they have less foreign competition due to increased price and quantity of the imports. Home consumers are worse off because of the increase in price. The home government benefits because of the additional tariff revenue generated from tariff. he efficiency loss from tariff is equal to area in Red

= 1/2 * (20 − 10) *0.25 = 1.25

Government revenue area in orange + green:

10 * 0.25+10*0.25 = 5

Gains from Terms of Trade(green)

=10*0.25

=2.5

dont trust me im no expert these losers made me fail a test bro this sucks
