Economic foundations

• Needs, Wants, and Economic Purpose: Explore the fundamental concepts of needs and wants, and understand the central purpose of economic activity.
• Key Economic Decisions: Investigate the core economic decisions that shape production and distribution.
• Economic Groups and Interactions: Identify the main economic groups and analyse the interactions between them.
• Economic Resources & Factors of Production: Explore the nature of economic resources and the four factors of production: land, labour, capital, and enterprise.
• The Basic Economic Problem & Weighing Up Choices: Explore the fundamental economic problem of scarcity and learn how to make informed decisions by weighing up costs and benefits.
• Costs, Benefits and Opportunity Cost: Understand costs, benefits and opportunity cost and how it is used when making choices

Resource allocation

• Understanding Markets and Resource Allocation: Explore the fundamentals of markets, resource allocation, and the interaction between buyers and sellers.
• Factor vs. Product Markets: Differentiate between factor and product markets and understand their roles in the economy.
• Understanding Specialisation and Division of Labour: Explore the core concepts of specialisation and division of labour, including their meaning, benefits, and drivers.
• Costs and Benefits of Division of Labour: Investigate the costs and benefits associated with the division of labour for both workers and firms, alongside the broader costs of specialisation and exchange.
• Economic Sectors: Primary, Secondary, and Tertiary: An introduction to the primary, secondary, and tertiary sectors, goods and services, and their importance in the UK economy.

How prices are determined

• Understanding Demand: Explore the fundamental concept of demand, its influencing factors, and how it's represented graphically.
• Factors Influencing Demand: Define demand and explain the concept of effective demand; Identify and explain the key factors that influence demand for goods and services; Analyse how changes in income, tastes, population, and related goods affect demand
• Drawing and Interpreting Demand Curves: Construct an individual demand curve from a set of consumer data; Explain why demand curves slope downwards from left to right; Distinguish between a movement along a demand curve and a shift of the demand curve
• Understanding Supply
• Drawing and Interpreting Supply Curves
• Equilibrium Price and Market Clearing
• Using Supply and Demand Diagrams
• Complements and Substitutes: Understanding Market Connections: Explore the relationship between different markets, focusing on complementary and substitute goods and how changes in one market impact related markets.
• Introduction to Price Elasticity of Demand: Learn about price elasticity of demand (PED), the difference between elastic and inelastic demand, and that price changes don't always cause equivalent changes in demand.
• Factors Affecting and Measuring PED: Explore the factors influencing PED, understand how to measure PED using the formula, and perform calculations from given data.
• Implications of PED for Producers and Consumers: Discuss the implications of PED for producers (e.g., pricing strategies) and consumers (e.g., purchasing decisions).
• Understanding Price Elasticity of Supply: Explore the concept of price elasticity of supply, differentiating between elastic and inelastic supply, and understanding how it measures the responsiveness of quantity supplied to changes in price.
• Factors Affecting Price Elasticity of Supply: Investigate the various factors that influence price elasticity of supply, including time, production capacity, and availability of resources. Also, consider scenarios where price changes don't lead to proportional supply changes.
• Implications of Price Elasticity of Supply: Analyse the implications of price elasticity of supply for producers and consumers, focusing on how it impacts revenue, pricing strategies, and market stability.

Production, costs, revenue and profit

• Understanding Economies of Scale: Explore the meaning of economies of scale and how they affect a business's average costs as production increases.
• Types of Economies of Scale: Examine the different types of economies of scale, including managerial, purchasing, financial, technical, and risk-bearing economies.
• Diseconomies of Scale and Business Growth: Learn about diseconomies of scale, their implications, and the costs and benefits of growth for a business.
• Business Objectives and Costs: Explore business objectives like profit, sales growth, and market share. Learn to identify and calculate total, average, fixed, and variable costs.
• Revenue and Profit Calculations: Learn how to identify and calculate total and average revenues. Understand the profit formula (total revenue - total costs) and strategies to increase profits.
• The Importance of Cost, Revenue, and Profit: Ethical Considerations: Examine the importance of cost, revenue, and profit for producers. Discuss how higher prices can incentivize production expansion, and address potential conflicts between producer motivations and ethical/moral interests.
• Introduction to Production and Productivity: Explore the core concepts of production and productivity, understanding their meanings and distinctions.
• Factors Influencing and Benefits of Productivity: Discover the factors that impact productivity and the advantages of boosting productivity in various contexts.

Competitive and concentrated markets

• Understanding Competitive Markets: Explore the key characteristics and definition of competitive markets.
• Impact of Competition on Price and Choice: Investigate how competitive markets affect price levels and the range of choices available to consumers.
• Intro to Non-Competitive Markets: Explore the main characteristics, definitions, and producer operations within non-competitive markets.
• Monopoly and Oligopoly: Impacts: Understand the impact of non-competitive markets on price and choice, and the causes/consequences of monopolistic/oligopolistic power.
• Understanding Market Structures: Explore the concept of market structures, the factors that define them, and learn how to identify them.
• Understanding the Labour Market: Explore the role and operation of the labour market, and how supply and demand determine wages.
• Gross Pay, Net Pay and Wage Differentials: Learn about wage differentials, the difference between gross and net pay, and how to calculate income.

Market failure

• What is Misallocation of Resources?: Explore the meaning of market failure as misallocation of resources and its implications.
• Government Intervention in Markets: Understand government intervention as a solution to market failure. Explore how the government tries to counter misallocation of resources.
• Understanding Externalities: This lesson introduces the concept of externalities, differentiating between positive and negative externalities and linking them to social and private costs/benefits.
• Positive & Negative Externalities in Action: This lesson explores the difference between positive and negative externalities, focusing on how production and consumption can lead to negative externalities, and identifying real-world examples.
