Case Study #1:

Cost Minimization and Production Decisions for a Corn

Farm

Scenario: The Weinandt Family Farm in Wynot, NE raises livestock and grows crops.

Commonly grown crops in Nebraska are corn and soybeans. You are a consultant hired to help a

farm similar to the Weinandt Farm make decisions about how much corn to grow this year.

Assignment Details

Objective:

To use Excel for data analysis and apply economic concepts to make informed production and

cost minimization decisions for a corn farm.

Instructions:

1. Market Data Analysis:

• Using the provided market data, create a market supply and demand graph in

Excel.

• Determine the market equilibrium price and quantity for corn.

2. Cost and Quantity Estimates:

• Using the provided firm cost and quantity estimates, calculate the following:

• Fixed Costs (FC)

• Variable Costs (VC)

• Average Total Cost (ATC)

• Average Fixed Cost (AFC)

• Average Variable Cost (AVC)

• Marginal Cost (MC)

• Graph ATC, AFC, AVC, and MC in Excel.

3. Cost Minimization Analysis:

• Based on your calculations, identify the range of quantities over which the

Average Total Cost (ATC) is minimized.

• Determine the optimal quantity of corn that the farm should aim to produce to

minimize costs.

4. Revenue and Profit Analysis:

• Using the optimal quantity identified, estimate the Total Revenue (TR), Total

Cost (TC), and Profit/Loss for the farm.

• Calculate these values using the market equilibrium price.

5. Production Decision:

• Based on your analysis, decide whether the farm should grow corn or leave the

fields bare.

• Provide a detailed explanation of your decision, supported by your calculations

and economic concepts.

6. Market Entry/Exit Analysis:

• Analyze whether farms will enter this market, leave the market, or remain

constant based on the profitability and cost structure.

• Explain your reasoning using economic theory related to perfectly competitive

markets.

Excel Data and Calculations

Step 1: Market Supply and Demand Graph

• Create a Market Supply and Demand Graph:

• Plot the supply and demand curves using the provided market data.

• Identify the equilibrium point where the supply and demand curves intersect.

Step 2: Firm Cost Calculations

• Calculate Costs:

• Use the provided data to calculate FC, VC, ATC, AFC, AVC, and MC.

• Use Excel formulas to automate these calculations for different levels of output.

Step 3: Cost Minimization

• Graph Costs:

• Create graphs for ATC, AFC, AVC, and MC.

• Identify the range of output where ATC is minimized.

Step 4: Revenue and Profit Calculations

• Estimate Revenue and Costs:

• Calculate TR using the formula: TR = Price * Quantity

• Calculate TC using the formula: TC = FC + VC

• Determine Profit/Loss using the formula: Profit/Loss = TR - TC

Step 5: Production Decision

• Decision Making:

• Analyze your calculations to determine if growing corn is profitable.

• Consider economic principles such as cost structures, market conditions, and

profitability.

Step 6: Market Analysis

• Market Dynamics:

• Discuss the potential for new farms to enter the market or existing farms to exit

based on profitability.

• Use economic theories related to market entry and exit in perfectly competitive

markets.

Submission Requirements

1. Excel File:

• Submit an Excel file with all your calculations, graphs, and analysis.

• Ensure all formulas and data are correctly inputted and clearly labeled.

2. Written Report:

• Submit a comprehensive report that includes the following sections:

• Introduction: Overview of the scenario and objectives.

• Market Analysis: Supply and demand graph, equilibrium price, and

quantity.

• Cost Analysis: Detailed calculations and graphs of ATC, AFC, AVC, and

MC.

• Revenue and Profit Analysis: Calculations of TR, TC, and Profit/Loss.

• Production Decision: Explanation of whether to grow corn or leave the

fields bare.

• Market Analysis: Discussion of market entry/exit dynamics.

• Conclusion: Summary of findings and recommendations.
