Theory of the Firm Multiple Choice Questions (MCQs)

📚 Quick Study Guide

• 🏭 Definition: The Theory of the Firm analyzes how firms make decisions to maximize profit.
• 💰 Profit Maximization: Firms aim to maximize profit, which is the difference between total revenue (TR) and total cost (TC): $Profit = TR - TC$.
• 📈 Production Function: Relates inputs (labor, capital) to output: $Q = f(L, K)$. Where Q is the quantity of output, L is labor, and K is capital.
• ⚖️ Cost Concepts:
  • 💸 Fixed Costs (FC): Costs that do not vary with output.
  • Variable Costs (VC): Costs that vary with output.
  • Total Cost (TC): $TC = FC + VC$
  • Average Total Cost (ATC): $ATC = \frac{TC}{Q}$
  • Marginal Cost (MC): The change in total cost from producing one more unit: $MC = \frac{\Delta TC}{\Delta Q}$
• 📊 Revenue Concepts:
  • Total Revenue (TR): $TR = P \times Q$, where P is the price and Q is the quantity.
  • Average Revenue (AR): $AR = \frac{TR}{Q} = P$
  • Marginal Revenue (MR): The change in total revenue from selling one more unit: $MR = \frac{\Delta TR}{\Delta Q}$
• 🎯 Optimal Output Rule: Firms maximize profit where Marginal Revenue (MR) equals Marginal Cost (MC): $MR = MC$.
• 🏢 Market Structures: Perfect competition, monopoly, oligopoly, and monopolistic competition each affect firm behavior differently.
