What does economics deal with? • Economics is a social science and can also be used to describe the way the world actually works • Closely linked to political and social systems – economic policies can affect political choices and vice versa • Study of economics focusses on: What /How / For whom to produce?? “The first lesson of economics is scarcity: there is never enough of anything to satisfy all those who want it. The first lesson of politics is to disregard the first lesson of economics.” Thomas Sowell Economics is about: • Matching what one needs (demand) with what one has (supply) • Provision of goods & services using resources INPUTS Resources: Labour Capital Entrepeneurs Land OUTPUTS NEEDS defined “It is the study of the way in which human-beings employ scarce resources (with alternative uses) to satisfy their many needs”. Ultimately the “study of choices” It is an art and a science! Economics is made up of two main disciplines: micro & macro economics Micro vs MACRO ECONOMICS Micro ⁻ economics at the small level ⁻ Individual, household or company level MACRO ⁻ economics at the big/high level ⁻ or level of government ⁻ looks at economy as a whole Macro economics • The study of the economy as a whole • Macroeconomics answers questions such as the following: Why is average income high in some countries and low in others? Why do prices rise rapidly in some time periods while they are more stable in others? Why do production and employment expand in some years and contract in others? What is the annual health care spend in SA? Micro economics • The study of how individuals, households and firms make decisions and how they interact with one another in markets. • Micro-economics answers questions like: Why is Sandton richer per capita than Gugulethu? Why are transaction numbers in North West falling? What will ticket prices be for the Gautrain? MARKET FORCES CIRCULAR FLOW MODEL SUPPLY VS DEMAND ECONOMETRIX | Leaders in Economic Insight The economy – where do you fit in? • Ever wondered what makes the economy go round? • Who are the participants in an economy and what are their roles? Income Production Aggregate Supply = total supply of goods & services produced within an economy at a given price level in a given time period Supply (AS) Spending Demand (AD) Aggregate Demand = total demand of goods & services in an economy at a given time period. It describes the relationship between price levels & quantity of output that firms are willing to provide Introduction to the Circular Flow Model • Shows how households, government and businesses are connected to each other by the flow of physical things (goods or labour) and of money (what pays for physical things). • Households, owners of production factors such as land, labour and capital make their services available to business sector, in exchange businesses pay households income (money) Money income (salaries, wages) costs Resource Market Land, labor, capital & entrepreneurial activity Resources Expenditure Resources Goods and services Goods and services Government Business Net taxes Net taxes Expenditure Goods and services Goods and services Goods and services Product Market Revenue Households Consumption expenditures No man/business is an island….

They depend on the technology used in production, and/or technological advances. Firms' expectations about future prices Number of suppliers (competition) Supply and Demand together Market equilibrium Price of a cup of coffee $0 $1 $2 $3 $4 $5 $6 Quantity supplied 0 6 9 12 15 18 21 Price of a cup Quantity of coffee demanded $0 24 $1 20 $2 16 $3 12 $4 8 $5 4 $6 0 At $3 the quantity demanded is equal to the quantity supplied! Equilibrium = situation where there is no tendency for change; when there is no reason for the market price of the product to rise or to fall. This occurs at the price at which the quantity demanded equals quantity supplied. At this price, the amount that consumers wish to buy is exactly the same as the amount that producers wish to sell. There are no unsatisfied buyers: buyers are able to purchase all they want to at that price. There are no unhappy sellers: producers are able to sell all they want to at that price. Shortage demand & excess supply Equilibrium occurs at a price of $3. The equilibrium quantity is 12 cups of coffee. • When price is above equilibrium of $3, quantity supplied is greater than quantity demanded. Firms are unable to sell all they want to at that price. There is an excess supply (surplus/glut) and there is pressure for the price to fall. • If price is below equilibrium, there is excess demand (shortage) and this creates pressure for the price to rise. • Only at the equilibrium price is there no pressure for price to rise or fall. Quantity Supplied Price Quantity Demanded Result What happens to price? 18 $5 4 QS > Q D excess supply price falls 15 $4 8 QS > Q D excess supply price falls 12 $3 12 QS = QD no surplus/no shortage equilibrium 9 $2 16 QD > QS excess demand price rises 6 $1 20 QD > QS excess demand price rises ECONOMIC GROWTH & DRIVERS OF GDP EXPLAINING KEY ECONOMIC CONCEPTS GROSS DOMESTIC PRODUCT CONSUMPTION INVESTMENT GOVERNMENT SPENDING BALANCE OF PAYMENTS ECONOMETRIX | Leaders in Economic Insight Gross domestic product (GDP) Economic Growth • GDP = market value (in Rand etc) of all final goods and services produced domestically in a single year /quarter (SA is a R3.8 trillion economy) • Most important measure of economic performance. • Economic growth = increase in an economy’s capacity to produce goods and services, compared from one period of time to another (= % change in GDP) • Economic growth literally refers to an economy that is getting bigger, not necessarily one that is getting better. • Increasing growth depends on the power of the economy to increase either the quantity and/or quality of production factors (labour/capital) over time or to introduce improved production techniques How is GDP measured/calculated? • In SA, Statistics South Africa (StatsSA) and the SA Reserve Bank is tasked with calculating GDP Consumer • 2 methods: expenditure is the Expenditure approach GDP is calculated by adding all expenditure: main contributor to GDP in SA (64%) GDP = C + I + G + (X - IM) Consumers + Investment (business) + Government + (eXports-IMports) Income approach GDP = Income (wages+rent+profits+income) – Depreciation – Indirect tax The rationale behind income approach is that total expenditures on final goods & services are eventually received by households & firms in form of wage, profit, rent, and interest income. By adding together all income earned by households/firms, one should obtain the same value of GDP as obtained using expenditure approach. Measuring GDP Removing the Price Effect Economic growth can be measured in: • nominal terms, which include inflation (eg if this year inflation is 3% and we have 2% economic growth, nominal GDP will have risen by 5%). • real terms, which are adjusted for inflation (price rises) - price effect is stripped out as it doesn’t show increase in capacity. When we think of the price of a good, we often think of its nominal price. The nominal price of a good is the cost of the good at the current price level. Changes in nominal prices result directly from changes in the price level due to inflation. The real price of a good is the cost of the good at a base year price level. For example if the cost of a ball in 2005 was R10 and the current cost of the ball is R12, we would say the real price of the ball is R10 with base year 2005. What is nominal prices? What is real prices? Measuring GDP Removing the Price Effect - example Real GDP and nominal GDP for an economy producing only shoes and video games over 3 years. We will assume consumption is the only part of this economy’s GDP. We will use year 1 for our base year. Year Price of Shoes Quantity of Shoes Price of Video Games Quantity of Video Games 1 R30 5 R40 5 2 R35 6 R42 10 3 R40 5 R50 8 Year 1: Nominal: (5 shoes x R30/shoe) + (5 video games x R40/game) = R350 Real: Because year 1 is the base year, real GDP = nominal GDP = R350 Year 2: Nominal: (6 shoes x R35/shoe) + (10 video games x R42/game) = R630 Real: (6 shoes x R30/shoe) + (10 video games x R40/game) = R580 Year 3: Nominal: (5 shoes x R40/shoe) + (8 video games x R50/game) = R600 Real: (5 shoes x R30/shoe) + (8 video games x R40/game) = R470 Notice that from year 2 to year 3 there was a slight decrease in the nominal GDP of the economy but a major decrease in the real GDP of the economy. This is very common in economics. It is also very possible for an economy’s nominal GDP to increase while it’s real GDP decreases. Growth in GDP Year GDP at current prices GDP at real prices 1 R350 R350 2 R630 R580 3 R600 R470 Question: What has been the growth in output between Y2 and Y1? Apply the growth formula: % growth = (Y2/Y1) -1 x 100 Current prices 80%; Real prices 65.7% Question: What has been the growth in output between Y3 and Y2? Current prices -4.8%; Real prices -18.9% Consumption Final Consumption Expenditure by Households • Consumption is the value of goods and services bought by people • Consumption is normally the largest GDP component. • Economic performance of a country is usually judged mainly in terms of consumption level and dynamics. • Consumption is divided according to the durability of the purchased objects. o durable goods (cars, television sets) o non-durable goods (food, beverages, cigarettes) o semi-durable goods (clothes, shoes) o services (restaurants, holidays, hairdresser) • Determinants: o Income (current & future expectations) o Savings Investment Gross fixed capital formation • Measure of amount that total physical capital stock increased in a country • Capital formation does not include financial assets such as stocks and securities. • Most volatile component of GDP • 3 ways to calculate/add By economic activity • Agriculture • Mining • Manufacturing • Electricity & water • Construction • Trade & accommodation • Transport & communication • Finance , insurance & real estate • Services By type of organisation • General government • Public corporations (eg Transnet) • Private business By type of asset • Residential buildings • Non-residential buildings • Construction works • IT & telecom equipment • Transport equipment • Machinery • Research & development • Computer software • Mineral exploration & evaluation • Cultivated biological resources Government Spending • Government expenditure = money that a government spends Expenditure occurs on every level of R126.4bn government, from local municipalities to provincial and national government R203.5bn R155.3bn departments • R157.3bn Not all basic needs are always met by the private sector. R64.4bn Some goods/services may not be produced, while others may be not be produced in enough quantity or at R62.2bn affordable rate for all citizens Government expenditure creation and implementation of these goods and services • Examples : military, police, public schools, health care programmes, public transportation infrastructure R199.6bn R206.2bn Where does government obtain its revenue to spend?

The more a country exports, the more domestic economic activity is occurring. More exports means more production, jobs and revenue. If a country is a net exporter, its gross domestic product increases, which is the total value of the finished goods & services it produces in a given period of time. Net exports increase the wealth of a country. Imports = purchase of foreign manufactured goods in buyer's domestic market. Countries often need to import goods that are either not readily available domestically or are available cheaper overseas. Often imported products provide a better price or more choices to consumers, which helps increase their standard of living. Importing gives access to important resources and products not otherwise available or at a cheaper cost. However, if a country imports more than it exports, more money is leaving the country than is coming in through export sales. Balance of payments (BoP) BoP = record of a country's: trade in goods & services with rest of world + real & financial assets with rest of world BoP consists of 2 parts: Measured by Current Account (C/A) Measured by Capital & financial account Current account balance = Exports of goods + Service receipts + Income receipts - Imports of goods + Service payments + Income payments + net (unilateral) transfers Services: eg shipping, banking and tourism Income Compensation of employees + Investment income (interest payments & dividends people receive from assets owned outside of their own country) Transfer when one party gives something but receives nothing in return, e.g. foreign aid • • • Capital account measures net (unilateral) transfers of assets between countries ( eg debt forgiveness / migrant transfers of assets they take with them when they move out of a country) Financial account = financial inflows - financial outflows A financial inflow when citizen sells an asset to another country, e.g. a U.S. Treasury bill is sold to Chinese investors A financial outflow when a citizen buys an asset from abroad, e.g. an American obtains a Swiss bank account. Capital and financial account balance = capital account balance + financial inflows - financial outflows BoP must balance Current Account Balance + Capital and Financial Account Balance = 0 The balancing account is called Gold and Cash Reserves ECONOMIC CYCLES TOOLS: MONETARY POLICY FISCAL POLICY ECONOMETRIX | Leaders in Economic Insight Business cycles Economies go through regular pattern of ups & downs in value of GDP = business cycle Business cycle fluctuations in economic output in a country, characterised by 4 phases: • Slump • Recession • Recovery • Boom Recession / slump Slump = overall economic activity starts to decline Recession = business cycle contraction = two quarters of negative growth rate of real GDP Depression: sustained, long-term downturn in economic activity in one or more economies. More severe downturn than economic recession. Very weak consumer spending & business investment; many business failures; rapidly rising unemployment; prices may start falling (deflation) Falling levels of consumer spending & confidence, lower profits for businesses; start to cut back on investment. Spare capacity increases + rising unemployment as businesses cut back, reduce stocks. Liquidations rise. Boom/ recovery Boom = High levels of consumer spending, business confidence, profits & investment. Prices & costs rise faster. Unemployment low as growth in economy creates new jobs Recovery = Things start to get better Consumers begin to increase spending; Businesses feel bit more confident, start to invest again and build stocks; but takes time for unemployment to stop growing Business cycle phases of SA since 1945 Source: SARB How does government stabilise the economy from shocks caused by the business cycle? • Government tries to stabilise the economy • Using macroeconomic policies/tools Fiscal Policy • Taxes • Government Spending Monetary Policy • Control of money supply • Interest rates Monetary Policy • Rests with the central bank (SA Reserve Bank) • Main goal is price stability – • SA has adopted inflation targeting in Feb 2000 = where central bank announces an explicit inflation target and implements policy to achieve this target directly. Fiscal Policy • Government spending – to stimulate the economy government creates jobs by employing people in infrastructure development, public works programmes etc • Taxes – to stimulate spending in the economy government cuts taxes people have more money left over they spend this money, which in turn creates demand and jobs UNPACKING THE SOUTH AFRICAN ECONOMY ECONOMETRIX | Leaders in Economic Insight Impact of global economy on SA SA in context of rest of world • According to the Global Competitiveness Report 2014/15, SA ranks 56th out of 144 economies surveyed globally • Chart below indicates most problematic factors for doing business in SA Most problematic factors for doing business in SA 0.2 Government instability/coups 1 Tax rates 1.2 Poor public health Tax regulations 1.5 Inflation 1.5 Foreign currency regulations 2.1 Access to financing 2.2 Crime and theft 2.5 Insufficient capacity to innovate 3 5.2 Poor work ethic in national labor force 7.4 Policy instability 9.8 Inadequate supply of infrastructure 11 Corruption 14.8 Inefficient government bureaucracy 16.9 Inadequately educated workforce 19.8 Restrictive labor regulations 0 5 10 15 20 25 SA GDP • SA average GDP Growth for 2014 was 1.5% • GDP growth for 2015 projected to be 1.9% BUT….
