Question
Consider the market for coffee in the small, isolated country of Krakozhia. Within Krakozhia, the domestic demand for coffee is:

\[ Q^d = 500 - 2p \]

and the domestic supply of coffee is:

\[ Q^s = -150 + 3p \]

### Trade and Surplus Analysis

#### (d) Open Trade Scenario
Suppose Krakozhia is open to trade and the world price is 150. Determine the following:
- **Domestic Quantity Supplied**: The amount Krakozhia produces domestically at the world price.
- **Domestic Quantity Demanded**: The amount Krakozhia consumes at the world price.
- **Quantity Exported**: The excess of domestic quantity supplied over domestic quantity demanded, indicating the amount exported.

#### (e) Graphing Domestic Supply and Demand
Create a graph with the following features:
- **Axes**: Label the horizontal axis as "Quantity" and the vertical axis as "Price."
- **Curves**: Plot the domestic supply and demand curves.
- **World Price**: Draw a horizontal line at the price level of 150 to represent the world price.
- **Intersections**: Identify and mark intercepts and relevant points where the supply and demand curves intersect.
- **Surplus Areas**: Shade and label the areas representing consumer surplus (above the world price and below the demand curve) and producer surplus (below the world price and above the supply curve).

#### (f) Surplus Calculations
- **Consumer Surplus**: Calculate the area between the demand curve and the world price.
- **Producer Surplus**: Compute the area between the world price and the supply curve.
- **Total Surplus**: Add the consumer surplus to the producer surplus.

### Welfare Analysis
Identify who benefits:
- **Made Better Off**: Analyze which group (consumers or producers) experiences an increase in surplus due to trade.
- **Made Worse Off**: Determine which group experiences a decrease in surplus.

This analysis is essential for understanding the economic implications of opening Krakozhia to international trade and the distribution of gains and losses among domestic consumers and producers.
