1 Intro Macro Module 1: Introduction to Economics This module covers: What is economics, why it matters. Supply and Demand What is economics? The study of how society manages its scarce resources. This requires choices, both at the individual level and the societal level. Why study economics? Economic analysis can help us analyze the choices we face as a society, and provide a framework for evaluating government policy decisions. How do we manage our scarce resources? For the most part, we use the market system, which is really just the combined actions of millions of individuals and firms. What actions? How much to work, what to buy, what to produce, how much labour to hire etc. Note that the market system does not require any kind of central planning, or anyone telling people what to do, or what to buy. People simply make choices, and resources are allocated according to these choices. In Canada, we have a mixed economy, in which we have decided to allocate some resources at the societal level, like infrastructure spending, education spending, and health spending. But these choices are not made separately from the market system, they still exist within it. How much we spend on education, for example, depends on wages and the cost of supplies determined in the market. Societal decisions mostly come in the form of government policy, such as what to tax, how much to tax it, and how to spend those tax revenues. Tax policy is often used to achieve societal objectives, like reducing pollution, reducing inequality, or encouraging innovation. This can involve the use of taxes and subsidies to affect the behaviour of buyers in a market. What do individual and societal choices depend on? Needs and wants, but also prices. (See Video 1 for more discussion of prices) ©Dennis Ng 2020 2 Supply and Demand Demand Demand curve: graph relating the price of a good and the quantity demanded In general, when prices rise, quantity demanded falls. There are some exceptions, explored in more detail in micro courses. Changes in various factors can cause the demand curve to shift: eg. income, prices of complements and substitutes, tastes and preferences, population etc. Supply Supply curve: graph relating the price of a good and the quantity supplied In general, when prices rise, quantity supplied also rises. Factors that cause the supply curve to shift: eg. input prices, technology, number of sellers What’s usually missing from a microeconomic discussion of supply and demand: Time. (See Video 1 for more discussion of Supply and Demand) Video 1 Questions You should be able to answer the following questions after watching Video 1. 1. Prices: What is a price? Does it represent the value of something? Why are prices important? What role do they perform in a market economy? 2. Why must we take time into account when analyzing supply and demand? What disruptions can a timing difference between a shift in demand and a shift in supply cause in the market for a good or service? 3. Explain the circular flow model of the economy. ©Dennis Ng 2020 1 Intro Macro Module 2: Standard of living, production, and growth This module covers: Measuring standard of living: Gross Domestic Product (GDP) Production and Growth How do we measure how the economy is doing? How do we measure economic progress? Economists use Gross Domestic Product (GDP) to keep track of everything produced in the economy in a given period of time, by adding up the total value of products and services bought and sold (please see your textbook for the formal definition). It is also used as a measure of society's well-being/standard of living. Canada’s GDP in 2019 was approximately $1.7 trillion, making it the 10th largest economy in the world. On a per capita basis, Canada’s 2019 GDP was $46,213 per person (17th in the world). For comparison, the GDP of the United States in 2019 was over $21 trillion, or $65,112 per person. Does this mean that people in the United States have a higher standard of living than people in Canada? How does the amount of production translate into standard of living? The idea is that societies that have more stuff will have a higher standard of living. So if we can produce more stuff, our standard of living will be higher. We can also think of it from the income perspective: the more we can produce, the higher our income (as a society), since we can sell all of the extra production that we don’t need, and use the income to purchase what we do need (or want). A higher income means we can obtain a higher standard of living. BUT: There are some problems with equating GDP with standard of living. (See section 6.5 of the textbook, which will be discussed in Video 2 in more detail). Comparing the components of GDP in Canada and the US: Canada Consumption 58% Investment 21% Government Spending 20% Exports 33% Imports -32% Sources: Statistics Canada, Bureau of Economic Analysis United States 70% 18% 17% 13% -18% [Note: as the textbook mentions, we care about Real GDP rather than nominal GDP, since Real GDP is adjusted for changes in prices. More on this when we discuss the CPI and inflation in Module 4.] Economists typically focus on the change in GDP from one year to the next. For most of the past 100 years, GDP has increased at a fairly steady rate, with some periods of faster growth, other periods of slower growth, and some periods of decline. A significant fall in GDP is a recession, and a recession that lasts for a long time is called a depression. Does a recession/depression mean standard of living has fallen? Generally speaking, if we are producing less as a country then our ©Dennis Ng 2020 2 incomes are lower, which means our standard of living will fall. But recessions tend to impact different sectors of the economy differently, so that some people will see a fall in their living standards (for example, if they lose their jobs), while others may see no change. We will discuss this more in Module 3. Something to note about the current recession is that it has impacted the entire economy at the same time, which means a very broad decline in standard of living, not just in Canada but all over the world. What if we borrow money and spend it? How does this affect GDP? Spending can be increased using both public debt (government borrowing) and private debt (borrowing by households and businesses). If we spend more, GDP increases, so it follows that standard of living will increase. But will this last? It depends on what we spend the money on. Productive debt: debt that finances new plant and equipment (or other capital accumulation) is productive debt. It adds to existing capital that, in turn, earns future debt service (i.e. will earn enough income to cover interest payments). Think of this as debt that is used to invest in the future, that is, we produce something now, like a new machine, that will produce even more in the future. So GDP increases in the present, and will also increase in the future. Unproductive debt: debt that is not self-financing. This occurs when we borrow and spend it on consumption. GDP increases today, but eventually the debt will have to be repaid, with interest, which means we will have less money available in the future. When using unproductive debt, the government is, in effect, borrowing from future taxpayers. GDP will be increased today, but decreased in the future. So current generations will have a higher standard of living, but this reduces the standard of living of future generations. When households and businesses use unproductive debt, the result is the same, you are simply trading a higher standard of living today for a lower standard of living in the future, which is the opposite of how human progress has been achieved since the dawn of civilization. There is evidence that debt has become much less productive over time. Some numbers: Year 1994 2019 Global GDP $28 trillion $87 trillion Global Debt $40 trillion $250 trillion Over the 25 years from 1994 to 2019, global GDP grew at approximately 4.6% per year. Over the same time period, global debt grew at 7.6%. This is unsustainable (to be discussed in more detail in our special topics series). ©Dennis Ng 2020 3 Economic Growth A country's standard of living depends on its ability to produce goods and services. Why? They can be sold, and the income can be used to acquire other goods and services. Almost all of the economic growth in human history has happened in the last 200 years (to be discussed in more detail in our first special topic). Property Rights and Economic Growth Property rights are a key component in a well-functioning economic system. Would you go to the trouble of producing something if you knew it would be stolen as soon as you finished it? Property rights that are not enforced discourage investment. Throughout the history of civilization, nations with well-defined and enforced property rights have developed faster than nations that had neither. Just look at which countries today are developed versus those that are developing to see where property rights have been enforced consistently over the last two hundred years. The only exceptions to this are several oil-rich countries, but while these countries are wealthy, they have massive inequality, far more than exists in any other developed countries. Property rights apply to far more than just physical property. Importantly, they also apply to intellectual property. The development of the patent system went hand-in-hand with the tremendous innovation of the industrial revolution. What is the main driver of increases in standard of living? Productivity: the quantity of goods and services produced from each hour of a worker's time. What determines productivity? Capital: machines, technology, education and training (human capital), basically anything that enhances a person's ability to produce. Policies to improve productivity will be discussed in Video 2. The interaction of productivity, technology, and economic convergence, will be discussed in more detail in our first special topic. Economic Growth, Population Growth, and Demographics Rapid population growth stretches the resources of many developing countries. Birth rates tend to fall, however, as countries become richer. This leads to a demographic transition, whereby population growth falls despite longer life expectancy, which can lead to a higher ratio of elderly to the working age population. This puts a strain on the welfare system, as pensions and healthcare become more costly, but the tax base becomes smaller as the working age population shrinks, putting a greater burden on workers. This is an ongoing issue that Canada will have to deal with over the next decade and beyond. More details in Video 2. ©Dennis Ng 2020 4 Video 2 Questions You should be able to answer the following questions after watching Video 2. 1. Why is GDP a flawed measure of standard of living? 2. Why is it important to look at both the level of GDP and the growth rate of GDP? 3. How does the age structure of a country’s population affect economic growth? ©Dennis Ng 2020 1 Intro Macro Module 3: Unemployment Unemployment is the biggest economic policy issue that a country faces. But we need to look beyond the unemployment rate in order to get a full picture of unemployment in the economy. This is due to the way the unemployment rate is defined, as it excludes people who are categorized as being ‘out of the labour force’, and also does not give any indication of people who are underemployed. This is why it is important to also look at estimates of the labour force participation rate, as well as any estimates of underemployment. Measuring Unemployment Every month, Statistics Canada conducts a survey of 50,000 households, called the Labour Force Survey. Every person 15 and older is put in one of 3 categories: - employed - unemployed - not in the labour force A person is unemployed if that person is on temporary layoff or is looking for a job. Video 3 will go into more detail on Canada’s unemployment rate and how it is measured. Public Policy and Unemployment Government policies can affect the amount of frictional unemployment in the economy. How? 1. Through employment agencies, which provide information about job vacancies 2. Training programs for unemployed workers 3. Employment Insurance Employment insurance (EI) is a government program that partially protects workers’ incomes when they become unemployed. To qualify, a worker must have worked for some minimum amount of time over the past year. Workers then receive a fraction of their previous wages for a specified number of weeks. The minimum work period and number of weeks during which a worker will receive benefits depends on local labour market conditions. Benefits of EI: Reduces income uncertainty and allows for a longer job search, which often results in a better job than would have been found otherwise. Problems with EI: EI can increase unemployment: Unemployed workers may expend less effort in searching for a new job, and are more likely to turn down unattractive job offers. Note that this only applies when the economy is doing well, since during a recession, workers will be less picky about accepting jobs. More details on public policy and unemployment in Video 3. Employment and the state of the economy One way to define a recession is not purely by whether GDP is contracting, but if there is a large increase in the number of unemployed workers. Businesses often have to make hiring decisions based on their plans for the future: if they think the economy is doing well, then they may choose to expand, and will hire more workers. If they think economic prospects are poor, then they will ©Dennis Ng 2020 2 choose either to stop hiring, or to let go of workers. Obviously economic conditions will have a big effect on unemployment. Long-term unemployment, which typically occurs as a result of bad recessions, can have a particularly devastating impact on workers. Not only is income lost during the recession, but so is the opportunity to gain valuable skills and job experience, which will impact income for many years to come. But unemployment can also have a big effect on the economy. The onset of a recession can lead to a self-reinforcing cycle: say consumers cut back on spending for some reason (like, I don’t know, a global pandemic…). This causes businesses to cut back production due to a decline in revenues, and if conditions persist, businesses will start laying off workers. Unemployed workers lose income and cut back on spending, which leads to a further decline in revenues for businesses, and further job cuts, and lower spending, and so on. The purpose of programs like EI is to maintain incomes while people are out of work, to keep standards of living from falling, but also to stop this self-reinforcing cycle before it begins. If consumer incomes can be maintained, then they can keep spending and other businesses and workers do not lose income. This works in a normal recession, when only part of the economy is not doing well. The current recession has hit the entire economy, so the cushioning impact of EI will be less effective. More discussion on this in Video 3, and in the Special Topics of this course. Video 3 Questions You should be able to answer the following questions after watching Video 3. 1. What does it mean when we say that unemployment is a lagging indicator? 2. Why is it necessary to look at other statistics, like the labour force participation rate, in addition to the unemployment rate? 3. What might the impact of the Canadian Emergency Response Benefit (CERB) be over the next few months? 4. Although there were a huge number of initial layoffs at the beginning of the economic shutdowns in March, we should actually be more concerned about layoffs that are happening now. Why is that the case? ©Dennis Ng 2020 1 Intro Macro Module 4: Inflation Why should we care about inflation? Inflation is an increase in the cost of living. If our cost of living goes up but our income does not, then our standard of living has fallen, as we cannot purchase the same amount of goods and services as before. To counter this, many contracts (salaries, pensions) include cost of living adjustments, which are automatic increases tied to the rate of inflation. Another problem caused by inflation is that inflation always erodes the return you receive from saving money, since the benefit of any interest you earn is reduced by the fall in purchasing power. On the other hand, if you are a borrower and not a saver, then inflation benefits you. Inflation makes debt easier to repay, since the debt is repaid in dollars that are lower in value. This can have an effect on the financial decisions that people make (which I will discuss in Video 4). Real and Nominal Interest Rates Say I deposit $1000 in a bank account earning 2% interest per year. After one year I get $20 interest. Am I $20 richer than last year? If prices have risen, my dollars buy less than they did one year ago. Say inflation was 3%. So what used to cost $1000 now costs $1030. Overall, my purchasing power has actually fallen by $10. Interest rate bank pays: nominal interest rate Interest rate corrected for inflation: real interest rate Real interest rate = Nominal interest rate – inflation rate [approximately] In our example, real interest rate = 2% - 3% = -1% Is inflation a problem in Canada? The biggest economic concern facing central banks of developed economies, Canada included, for the last 4 decades has been the threat of high inflation. This threat was largely neutralized starting in the early 1990s, when central banks (and the Bank of Canada) began a policy of 'inflation targeting' with the goal of keeping inflation between 1%-3%. This policy was largely helped along by the trend of globalization, in particular the emergence of China as a low-cost producer of consumer goods, which has kept prices low for the last 20 years. Inflation in Canada today fluctuates mainly as a result of changes in the price of oil. Why not aim for 0% inflation? Why do we deliberately set a policy of reducing our purchasing power by 2% per year? The main reason is that policymakers want to avoid deflation at all costs. Deflation is associated with the most severe recessions in modern times (like the Great Depression), and while deflation can increase purchasing power, this will not lead to an increase in the standard of living. If businesses and individuals expect deflation, they may change their behaviour as a result. Businesses may cut back on production or they may layoff workers in order to cut costs. Individuals may choose to delay major purchases (like houses and cars) since they expect prices to be lower in the future. This feeds back into lower business production and less income for workers. Falling prices as a result of technological change is a huge boost to standard of living, but remember that inflation is measuring prices across the whole economy. Falling prices across the whole economy are an indication of major problems, as businesses must be cutting prices to sell excess inventory, which is a clear sign of recession. This will be discussed in more detail in Video 4. ©Dennis Ng 2020 2 Video 4 Questions You should be able to answer the following questions after watching Video 4. 1. Why do we need to avoid deflation when debt levels are high? 2. Does low inflation, as measured by the CPI, mean that inflation is low across the whole economy? ©Dennis Ng 2020 1 Intro Macro Module 5: Money and the Financial System What is money? Why do you accept money as payment? Isn't it just a piece of paper? Your textbook’s description of money, its history, and how money is created in the modern economy is not accurate. But it is still important to read chapter 14 so you get an idea of how most economists (and thus most economic policymakers in both government and central banks) think money works. This leads to misguided policies, as we will see when we discuss the financial crisis. The Barter System Note that the barter system described in your textbook is not exactly how it worked, and it oversimplifies how early economies functioned, since payment systems could actually be quite complex, even in the absence of what we would define as money. Yes, people exchanged goods and services directly, but they did not necessarily exchange them simultaneously. Instead, many societies created early forms of debt, which was simply an obligation to repay at some point in the future. So if you gave me something today, I would be obligated to repay you with some good or service in the future. In societies that were small enough that the buyer and seller were known to each other, this obligation was often very strong, and could even extend beyond the life of the buyer, so that their family would be responsible for repayment in the event of the buyer’s death. Many early societies also developed their forms of payment to the extent that these debt obligations could be traded. So if I bought something from you with a promise to repay you in the future, I could divest this obligation not just by repaying you, but instead by repaying someone else (likely with a different good or service), who would then be responsible for paying you, creating a chain of obligations. What this means is that there was no need for what the textbook refers to as a double coincidence of wants, which would have severely restricted the amount of trade that could occur within an economy. Instead, all that was required was trust in other members of society. As economies developed, they started keeping track of these debt obligations with a ledger system, which is simply a record of transactions. This meant the chain of obligations could be as long as you wanted, and buyers and sellers did not have to know each other for there to be trust, since the ledger would provide a record of the transaction. Obligations could be also be settled by netting debt contracts, that is, if the person who was originally owed an obligation incurred an obligation with someone else, this could cancel out the initial obligation. Essentially, the ledger system is exactly how money and the modern financial system functions today. What is money? One way to define money is by the functions it performs. For money to be widely used in transactions, it must fulfill the following three functions: 1. It is a unit of account: goods, services and financial assets are measured in terms of money. 2. It is a means of payment (or medium of exchange): buyers give money to sellers when they want some good or service in return. Following Borio (2018), “the means of payment ©Dennis Ng 2020 2 is a generally accepted instrument that settles (extinguishes) obligations.” 3. It is a store of value: money is expected to retain its value over a long period of time. We can use money to transfer purchasing power from one period to another. Note: our currency is an imperfect store of value since its value is eroded by inflation. Also, any asset functions as a store of value. So this is not a distinguishing feature of money, but any means of payment must also be a store of value, otherwise nobody would accept it as payment. This has happened to money repeatedly throughout history, as we shall see. Commodity Money and Fiat Money Commodity money: money that takes the form of a commodity that has value due to some alternative use. Eg. Gold, cigarettes An economy is operating under a gold standard if paper money can be converted into gold on demand. It is very rigid, since the amount of money in any economy is restricted by the amount of gold a country has. This lack of flexibility is the main reason it would be difficult to return to a gold standard. Fiat money: Money with no alternative use that is used as money because of government decree. The entire world is currently using a fiat money system after abandoning the gold standard (which we will discuss in Module 6). As Borio (2018) puts it: “At an even deeper level, money is debt in the form of an implicit contract between the individual and society. The individual provides something of value in return for a token he/she trusts to be able to use in the future to obtain something else of value. He/she has a credit vis-à-vis everyone and no one in particular (society owes a debt to him/her).” Fiat money is just a special form of IOU (that is, a debt obligation), or, in the language of economics, a financial asset (there are many other financial assets, eg. Stocks, bonds, mortgages etc.). A financial asset is simply a claim on someone else in the economy: a person, company, or government. One person's financial asset is also another person's debt (a financial liability). Thus, all financial assets in an economy equal all financial liabilities. Commodity money is a non-financial asset, and does not have a corresponding amount of debt. Why do we use fiat money? It is mainly based on trust. Because everyone trusts that money will continue to be accepted in exchange for something tomorrow, it is accepted as a form of payment today. It is also based on the fact that the government requires you to pay taxes with its own currency. So everyone in the economy must acquire this currency in order to pay their taxes. How is money created? The textbook does not describe this correctly. The textbook (and every economics textbook I have ever seen) describes a process whereby you deposit money in the bank, it lends a fraction of that to someone else, who then deposits it at another bank, and the loan is newly created money. That loans create money is the only accurate part of this description. Instead, please refer ©Dennis Ng 2020 3 to the notes below, and the Bank of England reading listed in the course outline (and at the end of this module). Also note that since deposits do not lead to loans, the concept of the money multiplier is not useful. To understand how money is created, we need to look at the different categories of money. Categories of money Currency is made up of notes in circulation, mostly held by households and firms, also held by banks to meet withdrawals. It is the part of the money supply issued by the Bank of Canada (Canada’s central bank, discussed in Module 6), representing less than 5% of the Canadian money supply. Bank deposits make up the bulk of money in Canada. These deposits are what the bank owes you, while a loan is what you owe the bank. We often use deposits as a means of payment without ever converting them into currency. Unlike currency, which is created by the Bank of Canada, bank deposits are mostly created by the banks themselves. When a bank makes a loan to a household or firm, it simply credits that amount to the customer's account, and new money is created (this happens within the same bank, not through a new deposit at another bank, as described in the textbook). Why can banks create money? Because we use the deposits themselves as a means of payment. When you buy a coffee with your debit card, what the bank owes you decreases by the amount of the payment, and what the bank owes the coffee shop increases by the amount of the payment. But no currency has changed hands. When you take out a loan to buy a car, the bank increases the car dealership's deposits (what the bank owes the car dealership) and you now owe the bank the price of the car. Again, no currency has changed hands, but the dealership can now spend that money, which didn't exist before you took out the loan. Note: when you deposit currency into a bank, the total amount of deposits increases, and currency in circulation decreases. If you make a withdrawal, the total amount of deposits decreases, and currency in circulation increases. The amount of money in the economy is unchanged in either case. However, if you make a loan repayment, currency in circulation decreases, but there is no corresponding increase in deposits. Thus, the amount of money in the economy decreases. Repaying a loan is the equivalent of destroying money. See Video 5 for more discussion of the money creation process and its implications. Central bank reserves are the amounts owed by the central bank to each commercial bank. They play a similar role for commercial banks as that of bank deposits for households and firms. Banks ©Dennis Ng 2020 4 make payments to each other every day (say when you make an e-transfer to someone at another bank), and these payments are processed by adjusting reserve balances at the Bank of Canada. The amount of these reserves does not affect the amount of money creation in the economy. Banks will choose to hold more or less reserves depending on the interest rate and the amount of withdrawals from depositors (in some countries with a slightly different central bank setup, the amount of bank reserves is independent of the interest rate). Instead, you should think of bank reserves as a separate form of money, which is not at all connected to the money that you use. Bank reserves are used only within the banking system itself as a means of payment (no individual or business can be paid with bank reserves, only banks with an account with the Bank of Canada). A bank is really just a ledger system for keeping track of all the debt obligations of itself (deposits) and borrowers (loans) and all the transactions completed using these obligations (does this remind you of anything? Go back and read the barter system section at the beginning of this module. All that’s changed from early economies to the modern economy is the complexity of this record-keeping). A central bank performs the ledger function for keeping track of obligations between banks. The Bank of International Settlements (BIS) performs the ledger function for keeping track of obligations between central banks, to settle international transactions. See Video 5 for a discussion of where cryptocurrency fits in. Can banks create an unlimited amount of money? The short answer is no. There are regulations in place to limit lending, and banks also decide how much to lend based on available profitable opportunities. This depends on interest rates, the perceived risk of the borrower, and how many households and firms wish to borrow money. It does not depend on the existing amount of bank deposits, since every loan creates a new bank deposit (this is the most important thing your textbook gets wrong). Note that while banks cannot create unlimited money, there is also no way to force them to create more money. Video 5 Questions 1. Why are banks able to create money? 2.

Available here: https://www.bis.org/publ/work763.pdf ©Dennis Ng 2020 1 Intro Macro Module 6: Money and The Financial System The financial system is made up of the institutions in the economy that help to people save for the future and help others borrow to invest in new and growing businesses. Savers earn interest in exchange for giving up their money for a period of time, while borrowers pay interest in exchange for using money for a period of time. What brings the two together? The typical answer is that this is what banks are for, but that’s not exactly true. Banks do provide interest for savings, and they do provide loans to borrowers, but we know from Module 5 that they are not simply acting as financial intermediaries, by taking deposits and using them to fund loans. Instead, banks fulfill two very important functions: First, as we saw in Module 5, banks facilitate virtually all of the payments that we make in a modern economy, since we use bank deposits as money. Second, banks allow both savers and borrowers to move their own money through time (rather than to each other). If I have no need to borrow and have extra income to save, I can put the money in a savings account and earn interest. In the future, I will have more money, so in effect I am exchanging some amount of money today to receive a larger amount of money in the future. If instead I need to borrow money, say, to make a large purchase like a house, I can get a mortgage from the bank (a loan to buy property), and then I will be responsible for repaying the bank the amount of the loan plus interest. Mortgages are repaid in equal installments over the life of the loan (typically 25 or 30 years), so I am receiving money today, and in exchange I am paying regular payments in the future. Large loans like mortgages require collateral, which is an asset that you own that you will have to give to the bank if you fail to make your mortgage payments. For a mortgage, the house you buy with the mortgage is the collateral, so if you fail to pay your mortgage the bank will own your house (this will be important to remember when we discuss the financial crisis). The collateral essentially replaces your own creditworthiness. In both cases, saving and borrowing, I am simply moving money through time, exchanging some of my income today for more in the future, or exchanging some of my income tomorrow for more today. Financial Markets The main way savers directly provide money to borrowers is through financial markets. There are two main financial markets, the bond market and the stock market. The Bond Market A bond is a debt contract, in which a company or a government borrows money from investors. The contract specifies the date on which the loan will be repaid, called the date of maturity, and also identifies the rate of interest. The amount that is borrowed is called the principal. Bonds can have terms to maturity that can vary from a few months to 30 years or longer, while the interest © Dennis Ng 2020 2 rate depends both on the term to maturity and the risk of the borrower. The risk of the borrower depends on an estimate of its probability of paying all the interest and principal of the bond. Bonds also typically require collateral in the form of property or other fixed assets of a company, which lowers the risk of not being paid. If the borrower fails to make an interest payment, the bond is in default, and the borrower will have to renegotiate the loan or declare bankruptcy. If bankruptcy occurs, then, in the case of a company, the bondholders own the company, and can sell the assets posted as collateral to get some of their money back. If a government defaults, too bad. A bond only transfers money directly from savers to borrowers when the bond is first issued. After that, the bond can be traded in the bond market, which means that whoever initially bought the bond from the company can now sell the bond to someone else. The majority of trading that happens in the bond market is between savers buying bonds from each other, and this does not provide any money to the bond issuer. The Stock Market A share of stock (or stock) is a claim to partial ownership in a firm. Stocks entitle shareholders to some of the firm’s profits, while bondholders only get interest on their bonds. As in the bond market, the firm only receives money when the shares are first issued, and the majority of trading that happens in the stock market is people buying stock from each other, which does not provide money to the firm. Why buy stocks? Firms can distribute profits to shareholders through regular payments, called dividends, or by repurchasing shares from the public. These amounts can often be higher than the interest rate paid by savings accounts or bonds. You can also profit when the price of the stock goes up, and you sell it for more than you paid for it (the same can be said of bonds). If a company goes bankrupt, however, bondholders get paid first, before shareholders receive anything, and in most bankruptcies, shareholders receive nothing (and stocks have no collateral in the form of a firm’s assets). Stocks offer both higher risk, and potentially higher return. The Bank of Canada The Bank of Canada is the central bank of Canada. A central bank is an institution intended to regulate the amount of money in the economy. The Bank of Canada’s mandate is to achieve low and stable inflation, and to maintain financial stability. The central bank of the United States is called the Federal Reserve, often referred to as simply the Fed. Your textbook covers the Fed in detail. Functions of the Bank of Canada: 1. Issues currency 2. Acts as a banker for commercial banks, holding bank reserves, which are commercial bank deposits with the Bank of Canada. 3. Acts as a banker for the Government of Canada. 4. Influences the money supply, which is the amount of money available in the economy. © Dennis Ng 2020 3 This last function is called monetary policy, and changes to the money supply can profoundly affect the Canadian economy. Monetary policy will be covered in Module 7, in the context of the Great Financial Crisis. The Global Financial System One of the most important aspects of our financial system that you need to understand is that it is a truly global system, and that Canada’s financial system is highly integrated with the rest of the world. Video 6 will provide some background detail on the modern history of money in the global economy, and the nature of the global financial system. Video 6 Questions 1.
