Part c Macroeconomics Aggregate demand and the national economy 200 Aggregate supply and growth 231 10 Banking, money and interest rates 260 11 Inflation and unemployment 292 12 Macroeconomic policy 327 chapter aggregate demand and the national economy We turn now to macroeconomics This will be the subject for this third part of the book and most of the final part In particular, we will be examining five key topics The first is national output What determines the size of national output? What causes it to grow? Why growth rates fluctuate? Why economies sometimes surge ahead and at other times languish in recession? The second is employment and unemployment What causes unemployment? If people who are unemployed want jobs, and if consumers want more goods and services, then why does our economy fail to provide a job for everyone who wants one? The third is the issue of inflation Why is it that the general level of prices always seems to rise, and only rarely fall? Why is inflation a problem? But why, if prices fall, might that be a bad thing too? Why countries’ central banks, such as the Bank of England, set targets for the rate of inflation? And why is that target positive (e.g per cent) rather than zero? The fourth issue is the financial system We look at the role that financial institutions play in modern economies In doing so, we analyse the financial crisis of the late 2000s, the initial responses of policy makers to limit the adverse impact on economies and the subsequent responses to try to prevent a similar crisis reoccurring The final topic, which is the subject of the final part of the book, concerns a country’s economic relationships with other countries We look at international trade and investment and at the flows of foreign currencies around the world In this chapter, after a preliminary look at the range of macroeconomic issues, we then focus on the first of these issues: national output In doing this we identify the key purchasers of goods and services in the economy and the ways in which these purchasers are connected We analyse the potential determinants of their spending and so the factors that can influence the aggregate level of expenditure in the economy after studying this chapter, you should be able to answer the following questions: • • • • • • • What are the key macroeconomic issues faced by all countries? Who are the key groups of purchasers whose demands determine the total level of spending on a country’s goods and services? What are the various flows of incomes around the economy? What causes these flows to expand or contract? How we measure national output? What factors influence the level of spending by firms, households and government? What determines the level of national output at any one time? What is the effect on national income of an increase in spending? 8.1 Introduction to Macroeconomics 201 8.1 Introduction to Macroeconomics What issues does macroeconomics tackle? The first half of the book was concerned with microeconomics We saw how it focuses on individual parts of the economy and with the demand and supply of particular goods and services and resources The issues addressed by macroeconomists, by contrast, relate in one way or another to the total level of spending in the economy (aggregate demand) or the total level of output (aggregate supply) Many of these issues are ones on which elections are won or lost Is the economy growing and, if so, how rapidly? How can we avoid, or get out of, recessions? What causes unemployment and how can the rate be got down? Why is inflation a problem and what can be done to keep it a modest levels? What will happen to interest rates and if they were to change what would be their economic impact? How big a problem is government debt? Are banks lending too much or too little? If there were agreement about the answers to these questions, macroeconomics would be simpler – but less interesting! As it is, macroeconomics is often characterised by lively debate Economists can take different views on the importance of macroeconomic issues, their causes and the appropriate policy responses They can also disagree about how to analyse macroeconomic phenomena and, therefore, the actual approach to take in modelling macroeconomic relationships We shall be looking at these different views throughout this third part of the book This is not to suggest that economists always disagree and we will also identify some general points of agreement, at least among the majority of economists Problems of prediction. Another factor in addressing these questions is the difficulty of forecasting what will happen It is relatively easy to explain things once they have happened Predicting what is going to happen is another matter Few economists – or anyone else – foresaw the global banking crisis, credit crunch and subsequent economic downturn of the late 2000s Even those who thought banks had too little capacity to absorb losses and were making too many risky loans, could not predict exactly when a crisis would occur The role of expectations. A crucial element in macroeconomic activity is people’s expectations If people are optimistic about the future, consumers may be more inclined to spend and firms more inclined to invest If they are pessimistic, spending may fall But what drives these expectations? Again, this is a topic of lively debate Politics. Then there is the political context Governments may be unwilling to take unpopular measures, especially when an election looms So, should they give responsibility for decisions to other bodies? In many countries, interest rates are not set by the government but by the central bank In the UK, for example, it is the Bank of England that sets interest rates at the monthly meetings of the Monetary Policy Committee So just what are the macroeconomic issues that we will be studying in the following chapters? We can group them under the following headings: economic growth, unemployment, inflation and the economic relationships with the rest of the world, the financial well-being of individuals, businesses and other organisations, governments and nations, and the relationship between the financial system and the economy We will be studying other issues too, such as consumer behaviour, finance and taxation, but these still link to these major macroeconomic issues and, more generally, to how economies function Key macroeconomic issues Economic growth To measure how quickly an economy is growing we need a KI means of measuring the value of a nation’s output The mea- p sure we use is gross domestic product (GDP) However, to compare changes in output from one year to the next we must eliminate those changes in GDP which simply result from changes in prices When we have done so, we can then analyse rates of economic growth Governments hope to achieve a high rate of economic growth over the long term: in other words, growth that is sustained over the years and is not just a temporary phenomenon They also try to achieve stable growth, avoiding both recessions and excessive shortterm growth that cannot be sustained In practice, however, this can often prove difficult to achieve, as recent history has shown Figure 8.1 shows how growth rates have fluctuated over the years for four economies.1 As you can see, in all four cases there has been considerable volatility in their growth rates Therefore, while we observe most economies around the world growing over the long term, growth is highly variable in the short term with periods, like the late 2000s, Definitions Gross domestic product (GDP) The value of output produced within a country, typically over a 12-month period Rate of economic growth The percentage increase in output between two moments of time, typically over a 12-month period Note that EU-15 stands for the 15 member countries of the EU prior to May 2004: Austria, Belgium, Denmark, Germany, Greece, Finland, France, Ireland, Italy, Luxembourg, Netherlands, Portugal, Spain, Sweden and the UK 202 Chapter 8 Aggregate demand and the national economy Figure 8.1 Growth rates in selected industrial economies, 1965–2016 12 10 Annual % change in real GDP -2 -4 -6 1965 1970 1975 1980 1985 1990 1995 2000 2005 2010 2015 Notes: 2015 and 2016 based on forecasts;

in 1975, UK inflation reached over 23 per cent Figure 8.3 illustrates annual rates of consumer price inflation (annual percentage change in consumer prices) in the same four economies Definitions Underemployment When people work fewer hours than they would like at their current wage rate Inflation rate (annual) The percentage increase in prices over a 12-month period 8.1 Introduction to Macroeconomics 203 Figure 8.2 Standardised unemployment rates in selected industrial economies, 1965–2016 14 Unemployment (percentage of workforce) 12 10 1965 1970 1975 1980 1985 1990 1995 2000 2005 2010 2015 Notes: Figures from 2014 based on forecasts;

In other words, there will be a shortfall of foreign currencies The government will therefore have to borrow money from abroad, or draw on its foreign currency reserves to make up the shortfall This is a problem because, if it goes on too long, overseas debts will mount, along with the interest that must be paid; and/or reserves will begin to run low The exchange rate will fall. The exchange rate is the rate at which one currency exchanges for another For example, the exchange rate of the pound into the dollar might be £1 $1.50 If the government does nothing to correct the balance of payments deficit, then the exchange rate must fall, for example to $1.45 or $1.40, or lower (We will show just why this is so in Chapter 14.) A falling exchange rate is a problem because it pushes up the price of imports and may fuel inflation Also, if the exchange rate fluctuates, this can cause great uncertainty for traders and can damage international trade and economic growth and expenditure These are measured as so much per period of time Thus a person’s weekly wages would be an income flow; and spending, whether by cash, debit or credit card, would be an expenditure flow Tax receipts would be an income flow for governments; and money spent on imports would be an expenditure flow for a country There are three key accounts which are compiled for the main sectors of the economy: the household, corporate and government sectors and the economy as whole ■■ First, there is the income account which records the var- ious flows of income alongside the amounts either spent or saved Economic growth refers to the annual real growth in a country’s income flows (i.e after taking inflation into account) ■■ Secondly, there is the financial account The financial balance sheet gives a complete record of the stocks of financial assets (arising from saving) and financial liabilities (arising from borrowing) of a sector, and include things such as currency, bank deposits, loans, bonds and shares Changes in such balances over time (flows of new saving and borrowing) have been key in explaining the credit crunch and subsequent deep recession of the late 2000s/early 2010s ■■ Thirdly, there is the capital account which records the stock of non-financial (physical) wealth, arising from acquiring or disposing of physical assets, such as property and machinery Changes over time (inflows and outflows) in the capital balance sheets of the different sectors give important insights into relationships between the sectors of the economy and to possible growing tensions The national balance sheet is a measure of the wealth of a country It can be presented so as to show the contribution of each sector and/or the composition of wealth The balance of a sector’s or country’s stock of both financial and non-financial wealth is referred to as its net worth Figure 8.4 presents the national balance sheet for the UK since 1997 It shows the actual value (£) of the stock of net worth and its value relative to the value of output from domestic production over a 12-month period: i.e annual gross domestic product (see the appendix to this chapter for an analysis of the measurement of GDP) In 2014, the net worth of the UK was £8.1 trillion, equivalent to 4.4 times the Sector accounts KI 21 There are two main types of accounts used to show the p 148 financial position of individuals, businesses and other organisations, governments and nations The first type, known as a balance sheet, shows the stock of assets and liabilities An asset is something owned by or owed to you Thus money in your bank account is an asset A liability is a debt: i.e something you owe to someone else, such as outstanding balances on your credit card(s) At any given moment in time, we will be holding a certain amount of assets and liabilities The same applies to organisations, governments and countries The second type, known as an income and expenditure account or profit and loss account, shows flows of incomes Definitions Balance of payments account A record of the country’s transactions with the rest of the world It shows the country’s payments to or deposits in other countries (debits) and its receipts or deposits from other countries (credits) It also shows the balance between these debits and credits under various headings Exchange rate The rate at which one national currency exchanges for another The rate is expressed as the amount of one currency that is necessary to purchase one unit of another currency (e.g €1.25 £1) 8.1 Introduction to Macroeconomics 205 Figure 8.4 UK net worth 9000 500 8000 480 460 7000 440 6000 £ billions 400 4000 380 3000 360 2000 340 1000 Percentage of GDP 420 5000 320 1997 1999

person The stock of net worth fell for two consecutive years – 2008 and 2009 – at the height of the financial crisis and the economic slowdown These various accounts are part of an interconnected story detailing the financial well-being of a country’s households, corporations and government To illustrate how, consider what would happen if, over a period of time, you were to spend more than the income you receive – a deficit on your income account To finance your excess spending you could perhaps draw on any financial wealth that you have accumulated through saving Alternatively, you might fund some of your spending through a loan from a financial institution, such as a bank Either way, your financial balance sheet will deteriorate Or you may dispose of some physical assets, such as property, causing the capital balance sheet to deteriorate But however your excess spending is financed, your net worth declines Key Idea 30 alance sheets affect peoples’ behaviour The size B and structure of governments’, institutions’ and individuals’ liabilities (and assets too) affect economic well-being and can have significant effects on behaviour and economic activity The importance of balance sheet effects in influencing behaviour and, hence, economic activity has been recognised increasingly by both economists and policy makers, especially since the financial crisis of 2007–9 Yet there remains considerable work to be done in understanding KI 31 their effects and so in devising the most appropriate policies p 205 Pause for thought Is the balance of payments account an income and expenditure account or a balance sheet? Financial stability A core aim of the government and the central bank is to ensure the stability of the financial system After all, financial markets and institutions are an integral part of economies Their well-being is crucial to the well-being of an economy Furthermore, because of the global interconnectedness of financial institutions and markets, problems can spread globally like a contagion The financial crisis of the late 2000s showed how financially distressed financial institutions can Definition Central bank A country’s central bank is banker to the government and the banks as a whole (see Section 10.2) In most countries the central bank operates monetary policy by setting interest rates and influencing the supply of money The central bank in the UK is the Bank of England; in the eurozone it is the European Central Bank (ECB) and in the USA it is the Federal Reserve Bank (the ‘Fed’) 206 Chapter 8 Aggregate demand and the national economy cause serious economic upheaval on a global scale Therefore models of the macroeconomy need to incorporate financial markets and institutions and to capture the interaction between the financial system and the macroeconomy As we shall see in Chapter 10, a major part of the global response to the financial crisis has been to try to ensure that financial institutions are more financially resilient In particular, financial institutions should have more lossabsorbing capacity and therefore be better able to withstand ‘shocks’ and deteriorating macroeconomic conditions Government macroeconomic policy From the above issues we can identify a series of macroeconomic policy objectives that governments might typically pursue: ■■ High and stable economic growth ■■ Low unemployment ■■ Low inflation ■■ The avoidance of balance of payments deficits and excessive exchange rate fluctuations ■■ The avoidance of excessively financially-distressed sectors of the economy, including government ■■ A stable financial system Unfortunately, these policy objectives may conflict For ex- KI 29 ample, a policy designed to accelerate the rate of economic p 177 growth may result in a higher rate of inflation, a balance of payments deficit and excessive lending Governments are thus often faced with awkward policy choices, further demonstrating how societies face trade-offs between economic objectives (see Section 7.4) Recap Macroeconomics, like microeconomics, looks at issues such as output, employment and prices; but it looks at them in the context of the whole economy Among the macroeconomic goals that are generally of most concern to governments are economic growth, reducing unemployment, keeping inflation low and stable, avoiding balance of payments and exchange rate problems, avoiding excessively financially-distressed economic agents (i.e households, businesses and governments) and ensuring a stable financial system 8.2 The Circular Flow of Income Model How is spending related to income and who are the key groups of purchasers in the economy? One way in which the objectives are linked is through their relationship with aggregate demand (AD) This is the total spending on goods and services made within the country by four groups of people: consumers on goods and services (C), firms on investment (I), the government on goods, services and investment (such as education, health and new roads) (G) and people abroad on this country’s exports (X) From these four we have to subtract any imports (M) since aggregate demand refers only to spending on domestic firms Thus:2 AD = C + I + G + X - M To show how the objectives are related to aggregate de- TC p 12 mand, we can use a simple model of the economy This is the circular flow of income model and is shown in Figure 8.5 It is an extension of the model we looked at back in Chapter 1 (see Figure 1.5 on page 15) If we look at the left-hand side of the diagram we can identify two major groups: firms and households Each group has two roles Firms are producers of goods and services; they are also the employers of labour and other factors of production Households (which include all individuals) are the consumers of goods and services; they are also the An alternative way of specifying this is to focus on just the component of each that goes to domestic firms We use a subscript ‘d’ to refer to this component (i.e with the imported component subtracted) Thus AD = Cd + Id + Gd + X suppliers of labour and various other factors of production In the diagram there is an inner flow and various outer flows of incomes between these two groups Before we look at the various parts of the diagram, a word of warning Do not confuse money and income Money is a stock concept At any given time, there is a certain quantity of money in the economy (e.g £12 trillion) But that does not tell us the level of national income Income is a flow concept, measured as so much per period of time The relationship between money and income depends on how rapidly the money circulates: its ‘velocity of circulation’ (We will examine this concept in detail later on.) If there is £1 trillion of money in the economy and each £1 on average is paid out as income twice each year, then annual national income will be £2 trillion Definition Aggregate demand (AD) Total spending on goods and services made in the economy It consists of four elements, consumer spending (C), investment (I), government spending (G) and the expenditure on exports (X), less any expenditure on foreign goods and services (M): AD = C + I + G + X - M 8.2 The Circular Flow of Income Model 207 Figure 8.5 The circular flow of income The inner flow, withdrawals and injections The inner flow Firms pay money to households in the form of wages and salaries, dividends on shares, interest and rent These payments are in return for the services of the factors of production – labour, capital and land – that are supplied by households Thus on the left-hand side of the diagram, money flows directly from firms to households as ‘factor payments’ Households, in turn, pay money to domestic firms when they consume domestically produced goods and services (Cd) This is shown on the right-hand side of the inner flow There is thus a circular flow of payments from firms to households to firms, and so on If households spend all their incomes on buying domestic goods and services, and if firms pay out all this income they receive as factor payments to domestic households, and if the velocity of circulation does not change, the flow will continue at the same level indefinitely The money just goes round and round at the same speed and incomes remain unchanged Pause for thought Would this argument still hold if prices rose? In the real world, of course, it is not as simple as this Not all income gets passed on round the inner flow; some is withdrawn At the same time, incomes are injected into the flow from outside To help understand this we need to recognise that there other groups of purchasers (i.e demanders) So far we have identified households and firms as two key groups in the economy If we introduce government into our model we have a third group While this increases the complexity of our model, it makes it more realistic and increases the ways in which the total spending on goods and services in the economy can be affected A fourth group in our economic model is overseas purchasers This group comprises the foreign equivalents of our three domestic groupings For instance, it includes French households and Japanese car manufacturers The final group in the model is financial institutions, such as banks and building societies, and they play a key role These institutions provide the link between those who wish to borrow and those who wish to save In other words, they are ‘intermediaries’, which allow some in the economy to save while others borrow For instance, they can provide firms with the access to the credit they need to fund investment projects, such as the purchase of new machinery Definition The consumption of domestically produced goods and services (Cd) The direct flow of payments from households to firms for goods and services produced within the country 208 Chapter 8 Aggregate demand and the national economy Let’s now incorporate our additional purchasers and the financial system into our model We begin by focusing on the withdrawals from and injections into the inner flow Withdrawals (W) Only part of the incomes received by households will be spent on the goods and services of domestic firms The remainder will be withdrawn from the inner flow Likewise only part of the incomes generated by firms will be paid to UK households The remainder of this will also be withdrawn There are three forms of withdrawals (or ‘leakages’ as they are sometimes called) Net saving (S). Saving is income that households choose not to spend but to put aside for the future Savings are normally deposited in financial institutions such as banks and building societies This is shown in the bottom centre of the diagram Money flows from households to ‘banks, etc’ What we are seeking to measure here, however, is the net flow from households to the banking sector We therefore have to subtract from saving any borrowing or drawing on past savings by households to arrive at the net saving flow Of course, if household borrowing exceeded saving, the net flow would be in the other direction: it would be negative Net taxes (T). When people pay taxes (to either central or local government), this represents a withdrawal of money from the inner flow in much the same way as saving: only in this case, people have no choice! Some taxes, such as income tax and employees’ national insurance contributions, are paid out of household incomes Others, such as VAT and excise duties, are paid out of consumer expenditure Others, such as corporation tax, are paid out of firms’ incomes before being received by households as dividends on shares (For simplicity, however, taxes are shown in Figure 8.5 as leaving the circular flow at just one point It does not affect the argument.) When, however, people receive benefits from the government, such as unemployment benefits, child benefit and pensions, the money flows the other way Benefits are thus equivalent to a ‘negative tax’ These benefits are known as transfer payments They transfer money from one group of people (taxpayers) to others (the recipients) In the model, ‘net taxes’ (T) represent the net flow to the government from households and firms It consists of total taxes minus benefits Import expenditure (M). Not all household consumption (C) is of totally home-produced goods (C d) Households spend some of their incomes on imported goods and services, or on goods and services using imported components Although the money that consumers spend on such goods initially flows to domestic retailers, it will eventually find its way abroad, either when the retailers or wholesalers themselves import them, or when domestic manufacturers purchase imported inputs to make their products This expenditure on imports constitutes the third withdrawal from the inner flow This money flows abroad As we shall see, households are not the only group to purchase imported goods and services or goods and services using imported components: firms and government too These expenditures also contribute towards the sum of import expenditures (M) and affect the level of aggregate demand Total withdrawals are simply the sum of net saving, net taxes and the expenditure on imports: W=S+T+M Injections (J) Only part of the demand for firms’ output arises from consumers’ expenditure The remainder comes from other sources outside the inner flow These additional components of aggregate demand are known as injections (J) There are three types of injection Investment on domestically produced goods (Id ). This is firms’ spending on domestically produced goods and services after obtaining the money from various financial institutions – either past savings or loans, or through a new issue of shares They may invest in plant and equipment or may simply spend the money on building up stocks of inputs, semi-finished or finished goods Not all of the investment expenditure (I) undertaken by domestic firms is on totally home-produced goods Investment expenditure on goods and services produced overseas contributes towards import expenditure (M) Government expenditure on domestically produced goods and services (Gd ). When the government (both central and local) spends money on goods and services produced by domestic firms, this counts as an injection (Note that government expenditure in this model does not include state benefits These transfer payments, as we saw above, are the equivalent of negative taxes and have the effect of reducing the T component of withdrawals.) As well as providing goods and services by purchasing from firms, governments can actually own and run operations themselves In these cases, the wages of publicsector staff will also be a component of the government’s expenditure and are a flow of factor payments to households Definitions Withdrawals (W) (or leakages) Incomes of households or firms that are not passed on round the inner flow Withdrawals equal net saving (S) plus net taxes (T) plus import expenditure (M): W = S + T + M Transfer payments Moneys transferred from one person or group to another (e.g from the government to individuals) without production taking place Injections (J) Expenditure on the production of domestic firms coming from outside the inner flow of the circular flow of income Injections equal investment (Id) plus government expenditure (Gd) plus expenditure on exports (X) Index I:7 change in demand 37 change in supply 37 monopoly 110 output and 37–9, 110 equity 167, 176, 183 established
