Supply and Demand Model Overview

Supply and Demand Model

• Demand Curve: Slopes downward, showing inverse relationship between price and quantity demanded.
• Supply Curve: Slopes upward, showing direct relationship between price and quantity supplied.
• Equilibrium: Intersection of supply and demand curves, determining market price and quantity.
• Demand Determinants: Consumer preferences, income levels, substitute/complement prices, population, and future price expectations.
• Supply Determinants: Input costs, technological advancements, number of producers, taxes, subsidies, and future price expectations.
• Energy Market Applications: Price elasticity of demand (e.g., gasoline), supply shocks (e.g., OPEC decisions, natural disasters), and policy interventions (e.g., carbon taxes).

Static Efficiency

• Definition: Allocating resources to maximize total net benefits (consumer and producer surplus) at a specific point in time.
• Efficiency Criteria: Marginal benefit (MB) equals marginal cost (MC) in production and consumption; no externalities.
• Energy Market Applications: Evaluating whether current resource extraction aligns with future needs and optimal resource use.

Dynamic Efficiency

• Definition: Allocating resources over time to maximize total net benefits, considering future availability and costs.
• Key Concepts: Trade-offs between present and future consumption, incorporating scarcity and technological change.
• Hotelling's Rule: The price of exhaustible resources should rise at the rate of interest, assuming no changes in extraction costs or technology.
• Energy Market Applications: Optimizing extraction of non-renewable resources, balancing investments in renewable vs. fossil fuels.
• Examples: Evaluating current oil extraction rates and their alignment with future needs, planning renewable energy infrastructure investments.

Social Discount Rate

• Definition: Rate used to discount future benefits and costs to their present value in long-term project/policy evaluations.
• Key Components: Pure rate of time preference (society's preference for present vs. future benefits), and opportunity cost of capital (return on investment in alternative projects).
• Energy Economics Role: Determines the value assigned to future benefits from renewable energy projects, crucial for climate change policies.
• Debates: High discount rate favors short-term projects, undervaluing future benefits; low discount rate gives more weight to future benefits, supporting climate change mitigation.
• Energy Market Applications: Assessing nuclear power plants' viability (high upfront costs/long-term benefits), evaluating subsidies for solar energy.
