Introduction To Economics What is economics?
Week 1: Key terms and words Production Consumption Goods Services Scarcity Choice Natural resources Land Labour Capital Enterprise Needs Wants Choice Opportunity cost Modelling Economic systems Positive & Normative Macroeconomics Microeconomics
What is Economics? Concerned with production …and with consumption …and with scarcity …and anything to do with the process of satisfying human wants The study of how we apply limited resources to unlimited wants
The major economics issues What, how and for whom? What goods and services to produce? How to produce? For whom to produce?
What is the difference between “goods” …………..and “services”?
Scarcity The fundamental problem of economics Unlimited wants Limited resources So we cannot have everything we want Generates a need to make choices
Factors of production (Resources) Labour – human resources Land and raw materials – natural resources Capital – Manufactured resources
Labour Limited number Limited skills Location Entrepreneurs Organise productive resources Specialised form of labour or fourth factor of production? Can make or break business
Land and raw materials Land area is finite Raw materials are finite diminish over time are not evenly distributed between nations
Capital Manufactured resources Factories Machines Transport Other equipment Infrastructure – roads, communications etc Limited in quantity and by technology
Economics is also concerned with Demand and Supply Demand Related to wants Virtually unlimited Supply Related to resources Limited
Introduction to Economics Economic Systems
Demand and supply Markets Demand for goods and services Supply of goods and services Price movements Economic systems – level of control Goal – To use scarce resources to meet the needs and wants of people so as to improve their welfare (or well-being)
Question?????? Is their any difference between needs and wants?
Economic Systems Command Economies Free Market Economies Mixed Economies
Command Economies Land and capital collectively owned State planning - allocation of resources: Current consumption or future investment Output of each industry/company Distribution of output between consumers
Free Market Economies Price mechanism Shortage and surpluses Shortage -> price rises Surplus -> price falls Equilibrium: demand = supply Land and capital privately owned Firms seek to maximise profits Consumers seek best value for money Workers seek to maximise wages
Mixed Economies Mixture of public (state) and private sector ownership and activity State influence on key areas depending on government priorities Price and profit provide major incentives In practice ALL economies are a mixed Key distinction – how much is government involved?

Introduction to Economics Two branches: Macro- and Microeconomics
Macroeconomics MACRO – large, great (Greek) The economy as a whole Aggregate demand (spending) Aggregate supply Broad issues Growth Inflation Unemployment International trade/Balance of payments
Microeconomics MICRO – small (Greek – tiny) Individual companies Individuals Supply of, demand for, particular goods and services
Fundamental choices What should be produced? How should production be organised? For whom should production take place? Who chooses? Individuals/households Firms Governments
Opportunity Cost The cost of production or consumption in terms of the next best alternative, based on: Rational choices: Costs and benefits Consequences (positive or negative) Marginal costs Marginal benefits
Discussion You have all decided to study in the UK – but you could have gone to a University in your home country What are the costs and benefits of your decision? What is the opportunity cost of your studying in the UK?
Economic modelling How we describe economic concepts Diagrammatical – graphs and flow charts Mathematical Verbal Ceteris paribus – other things being equal
Economic modelling Examples: Production possibility curve Increasing opportunity costs Circular flow of goods and income
Production possibility curve Highly simplified Choice Increasing opportunity costs
Production possibility curve 2 Growth Investment – production of items not for immediate consumption
Economic analysis - modelling The circular flow of income Two key players - firms and households Two markets Goods markets real flows: goods and services money flows: consumer expenditure Factor markets real flows: services of labour and other factors money flows: wages and other incomes
Goods and services £ Consumer expenditure Wages, rent dividends, etc. £ Services of factors of production (labour, etc) The circular flow of goods and incomes
Introduction to Economics Positive and Normative Statements
Is economics a science? Positive versus Normative Economics Positive statements – facts Normative statements - values
Positive Statements Statements of fact Accuracy can be tested Objective Examples?
Normative Statements Statements of value Opinion Subjective Cannot be proved or disproved Examples?
