Demand and Supply in Financial Markets

Introduction to Demand and Supply

  • Definition and relevance of demand and supply in economics.
  • Focus on financial products and services rather than general goods.
  • Initial lectures will cover basic microeconomic concepts.

Price and Quantity

  • Price on the y-axis; quantity on the x-axis of the demand-supply curve.
  • Importance of understanding buyers and sellers in the market.
    • Buyers: Individuals or entities looking to purchase goods/services.
    • Sellers: Individuals or entities looking to sell goods/services.
  • Market regulates price based on demand and supply.

Concept of Optimum Price and Quantity

  • Determining optimum price and quantity for buying and selling products.
  • Consideration of different financial instruments (e.g., stocks, options).
  • Importance of optimizing investment returns.
    • Different investors have different goals (maximize profits vs. minimize losses).

Risk and Return

  • Relationship between risk and return in financial markets.
  • Different methods to quantify risk: standard deviation, beta, etc.
  • Importance of analyzing risk-return profile when investing.

Marginal Revenue

  • Definition: change in revenue associated with a unit change in output.
  • Marginal revenue is crucial for solving optimization problems.
  • Primal and dual problems in optimization.
    • Primal: Original optimization problem.
    • Dual: Mirror image of the primal problem, revealing deeper insights into optimization.

Utility Theory

  • Utility theory helps in understanding decision-making in finance.
  • Different investors have different demands based on risk appetite.
  • Decision-making involves choosing the optimal choice from a set of alternatives.

Expected Value in Decision-Making

    • Risk-averse: Prefers to avoid risk.
    • Risk-neutral: Indifferent between risk and certain outcomes.
    • Risk-seeking: Willing to take risks for potential higher returns.

Conclusion

  • Importance of understanding demand and supply in financial contexts.
  • Relationship between price, quantity, risk, return, and utility in investment decision-making.
  • Future discussions will delve deeper into specific financial instruments and their analysis.
