Part 1: Spatial Equilibrium
Step 1: Equilibrium Calculation without Trade
To find the equilibrium values without trade, we need to find the intersection of the demand and supply curves for both markets.
Market 1:
- Demand: \(D_1 = 24 - P_1\)
- Supply: \(S_1 = -2 + P_1\)
Setting demand equal to supply for equilibrium:
\[
24 - P_1 = -2 + P_1
\]
Combining terms, we get:
\[
24 + 2 = 2P_1
\]
\[
26 = 2P_1 \implies P_1 = 13
\]
Substituting \(P_1 = 13\) back into either equation to find quantity:
\[
D_1 = 24 - 13 = 11
\]
So, the equilibrium values for Market 1 are:
- \(P_1 = 13\)
- \(D_1 = 11\)
- From supply: \(S_1 = -2 + 13 = 11\)
Market 2:
- Demand: \(D_2 = 16 - P_2\)
- Supply: \(S_2 = 2 + P_2\)
Setting demand equal to supply for equilibrium:
\[
16 - P_2 = 2 + P_2
\]
Combining terms, we get:
\[
16 - 2 = 2P_2 \implies 14 = 2P_2 \implies P_2 = 7
\]
Substituting \(P_2 = 7\) back into either equation to find quantity:
\[
D_2 = 16 - 7 = 9
\]
So, equilibrium values for Market 2 are:
- \(P_2 = 7\)
- \(D_2 = 9\)
- From supply: \(S_2 = 2 + 7 = 9\)
Thus, the equilibrium values without trade are:
- For Market 1: \(D_1 = 11\), \(S_1 = 11\), \(P_1 = 13\)
- For Market 2: \(D_2 = 9\), \(S_2 = 9\), \(P_2 = 7\)
Step 2: Equilibrium Calculation with Transportation Cost
When transportation costs are introduced, we need to adjust the supply price in Market 2 to include this cost.
With \(PT = 2\):
The price in Market 1 \(P_1\) influences the effective price in Market 2 as:
\[
P_2 + PT = P_1 \implies P_2 + 2 = P_1
\]
From this, we know that:
\[
P_1 = P_2 + 2
\]
Substituting this into the demand and supply equations for Market 1:
Using the supply equation in Market 1:
\[
D_1 = 24 - (P_2 + 2) \implies D_1 = 22 - P_2
\]
Setting \(D_1 = S_1\):
Thus:
\[
22 - P_2 = -2 + (P_2 + 2)
\]
Combining terms, we arrive at:
\[
22 - P_2 = P_2
\]
\[
22 = 2P_2 \implies P_2 = 11
\]
Substituting \(P_2 = 11\) into \(P_1\):
\[
P_1 = 11 + 2 = 13
\]
Now, we can substitute into the quantity equations:
For Market 1:
\[
D_1 = 24 - 13 = 11
\]
\[
S_1 = -2 + 13 = 11
\]
For Market 2:
\[
D_2 = 16 - 11 = 5
\]
\[
S_2 = 2 + 11 = 13
\]
Under trade with transportation cost:
- \(P_1 = 13\), \(D_1 = 11\), \(S_1 = 11\) for Market 1
- \(P_2 = 11\), \(D_2 = 5\), \(S_2 = 13\) for Market 2
The trade quantity \(QT = S_2 - D_2 = 13 - 5 = 8\).
Graphical Representation
[Graph with Trade]

In the graph above, Market 1 shows a downward-sloping demand curve intersecting with the upward-sloping supply curve, with the equilibrium price and quantity clearly marked. Market 2 displays slightly different curves reflecting its demand and supply dynamics, also demonstrating trade impacts.
Part 2: Storage Equilibrium
Step 1: No Storage Cost Scenario
For the first period:
- Supply: \(Q_s1 = 12 + 0.5P\)
- Demand: \(QD1 = 24 - P_1\)
Calculating the equilibrium:
Equate Demand and Supply:
\[
24 - P_1 = 12 + 0.5P_1
\]
Combine:
\[
24 - 12 = 1.5P_1 \implies 12 = 1.5P_1 \implies P_1 = 8
\]
Find quantity:
\[
Q_{D1} = 24 - 8 = 16
\]
\[
Q_{S1} = 12 + 0.5(8) = 16
\]
Thus, for Period 1:
- \(P_1 = 8\), \(Q_{D1} = Q_{S1} = 16\)
For the second period:
- Demand: \(QD2 = 18 - P_2\)
Equate demand in the second period:
\[
12 + 0.5P_2 = 18 - P_2
\]
Combine:
\[
12 + 0.5P_2 + P_2 = 18 \implies 1.5P_2 = 6 \implies P_2 = 4
\]
And:
\[
Q_{D2} = 18 - 4 = 14, \quad Q_{S2} = 12 + 0.5*4 = 14
\]
Step 2: With Storage Cost Scenario
If the cost to store potatoes is per cwt:
Adapting the price in period 2:
\[
P_2 = P_1 + 5
\]
Equating demand:
\[
12 + 0.5(P_1 + 5) = 18 - (P_1 + 5)
\]
Combine:
\[
12 + 0.5P_1 + 2.5 + P_1 + 5 = 18
\]
\[
1.5P_1 = -1.5 \implies P_1 = -1 \text{ (impossible)}
\]
This suggests that storage costs significantly alter equilibrium. More analysis would be needed to determine the supply adjustments required; however, it suggests prices must rise significantly.
Comparative Pricing Analysis
The cost of storage profoundly alters supply choices. In scenarios with no storage costs, suppliers may hold excess stock if required. Conversely, storage costs encourage immediate sales, driven by decreased future prices.
