The Phillips curve shifted higher over the period. At a higher level of aggregate demand (a boom), there is a positive bargaining gap and inflation is positive. Firms in the economy use both the products of other firms in the economy and imported products as inputs. The empirical evidence suggests that the effects of QE in boosting aggregate demand are positive but small. With rising prices, a fall in real income among the losers may be masked by the fact that nominal incomes are rising, or at least not falling. Expected inflation over the year ahead is based on the previous year’s inflation. Figure 15.2 summarizes three causes of inflation. As we have seen in Unit 14, a rise in the debt burden depresses consumption because some affected households save to restore their target wealth and others find themselves credit-constrained. In fact, many central banks around the world have policies to target an inflation rate of 2%. After the initial increase in the workers’ bargaining power, the firms adjust the wages and prices by shifting the wage-setting curve, creating inflation. The process of rising wages and prices will continue as long as: In the example given, inflation rose while unemployment did not change, following a change in the competitive conditions facing firms that allowed them to raise their markup, increasing the owners’ profits. Helmut Schmidt was called the ‘super minister’ in the West German government of Chancellor Willy Brandt because he was both minister of economics and minister of finance. Use the same axes as in Figure 15.10 to plot inflation, expected inflation, and the bargaining gap in a single diagram. The last time you visited, you stopped reading here. The real interest rates for the four periods are: 3.4%, 2.3%, 1.8%, and –0.4% respectively. In Unit 10 we explained that, although the central bank sets the policy interest rate, commercial banks set the market interest rate (also referred to as the bank lending rate) that households and firms pay when they take out loans. Three causes of inflation: changes in bargaining power. Labour unions: Bargained wages and the union voice effect, 9.11 Labour market policies to address unemployment and inequality, 9.12. Policymakers globally believed there would be an inflation-stabilizing unemployment rate. Japan’s real interest rate turned from being positive to negative during the period. Measured primarily by changes in the gross domestic product (GDP), NBER measures the length of economic cycles from trough to trough or peak to peak. This prevents a wage-price spiral. Now consider: See Figure 15.4d for diagrams of the labour market model, the Phillips curve, and the multiplier model of aggregate demand. Inflation occurs due to the fact that the economy is no longer at the intersection of the two curves, and does not involve further moves in the curves. The bottom two rows in Figure 15.17 show that the slowdown led to rising unemployment and falling inflation, exactly as we would expect from a negative demand shock. In a 1958 paper, Phillips made another major contribution to the study of economics. The central bank will try to achieve zero unemployment while keeping the inflation at 2%. 1 GBP bought fewer USD on 24 Nov 2015 than one year earlier, so the USD appreciated against the GBP. Back then, anything with a whiff of exposure to real estate was at the centre of speculation. Figure 15.17 showed that this is what happened in the US after the tech bubble ended. Instead of fitting Phillips curves to the observations, as in Figure 15.6, the points are joined and dated. (2017). As long as employment remains above the labour market equilibrium, employees will be disappointed at the end of the year. Inflation and central bank independence: OECD countries. The reason was the phrase the campaign workers used: ‘The economy, stupid!’. The National Bureau of Economic Research (NBER) is the definitive source of setting official dates for U.S. economic cycles. Now, the hottest sectors in America are nearly all disruptive technologies. One advantage of using m is that it makes it easy to see that if the markup is fixed, then a rise in unit costs must imply a proportionate price rise (for example, an increase in unit costs of 5% must imply a price rise of 5%). Consumption then falls, which shifts the aggregate demand line down and the economy enters a recession, moving from point A to point B. Figure 15.20 illustrates the relationship between the degree of central bank independence in the mid-1980s, and average inflation between 1962 and 1990, across OECD countries. Instead, to keep aggregate demand close to the level it desires, the central bank can adjust the interest rate up and down by small amounts month-by-month. From the multiplier diagram in the lower panel, we know that a fall in investment spending shifts the aggregate demand line down, and leads to a new goods market equilibrium in the economy with lower output and higher unemployment. Shocks that move the Phillips curve by changing the labour market equilibrium are described as supply shocks, because the labour market represents production or supply in the economy. The lessons of Figure 15.6 about the instability of Phillips curves, and the high costs of unemployment incurred by countries in the 1980s as they brought inflation down, created the impetus. The Phillips curve has shifted up because expected inflation increased. New Zealand, which had high inflation in 1989, pioneered inflation targeting. Cheap essay writing sercice. Independence of central bank: Vittorio Grilli, Donato Masciandaro, Guido Tabellini, Edmond Malinvaud, and Marco Pagano. Now consider a boom, which takes the economy to lower unemployment at point B. Many central banks hit the zero lower bound for nominal interest rates, leading to a renewed interest in fiscal policy as a stabilization tool. MONIAC had tanks for each of the components of domestic GDP, such as investment, consumption, and government expenditures. Using simple diagrams like Figure 15.15 may give the impression that the central bank is able to stabilize the economy by accurate diagnosis of a shock and precise intervention with a change in the interest rate. At a lower level of aggregate demand (a recession), there is a negative bargaining gap and deflation. In the most recent period, the US economy has been able to lower its inflation rate with little effect on the unemployment rate. GBP depreciated against euro over the year. Quantitative easing involves the central bank lowering its official interest rate. Stagflation is my best guess for the future, where the economy grows only 1-1.5% over the next decade, yet real prices go up 3-6% on things we need, not manipulated hedonic CPI smoke and mirror equations that fool a majority of people into thinking everyone else is doing just fine, and they just need to work harder to catch up. Labour supply, labour demand, and bargaining power, 9.10. But in many other economies, especially smaller ones, an important channel for monetary policy is through the effect of interest rate changes on the exchange rate and the economy’s competitiveness in international markets, and hence on net exports. Clearing cached data will remove them. We begin by asking how inflation got a bad name. That is, the rise in prices satisfies firms, but the corresponding fall in real wages does not satisfy workers. How the rate of unemployment and the level of output in the economy affect inflation, the challenges this poses to policymakers, and how this knowledge can support effective policies to stabilize employment and incomes, Before his successful 1992 US presidential campaign, Bill Clinton’s electoral strategists had decided that two of their campaign issues should be health policy and ‘change’. ‘The Relation Between Unemployment and the Rate of Change of Money Wage Rates in the United Kingdom, 1861–1957’. ↩, Milton Friedman. The model in Figure 15.5 suggests that a policymaker who is able to adjust the level of aggregate demand can pick any combination of inflation and unemployment along the Phillips curve. The first column of Figure 15.8 reflects forward-looking behaviour. At B, inflation is equal to expected inflation plus the bargaining gap. They do not give a complete recipe for effective stabilization. Helmut Schmidt (1918–2015) was West German Chancellor from 1974 until 1982. At the level of the economy as a whole, the national pie to be divided between owners and employees shrinks when more has to be paid for imports. Beginning in the 1990s, governments increasingly took the view that central banks should be given responsibility for keeping the economy close to a target rate of inflation. Less spending means less demand, which induces businesses to lay off workers and cut back even further. For example, during the 2000s, it was estimated at 5.9% in the UK, and 7.7% in Germany. Inflation fell and remained low. This is because of the way that wage- and price-setters form their views about what will happen to inflation, which is called expected inflation. As a result, the high-inflation countries granted much more independence to their central bank, with a low inflation target embedded in official statutes. Figure 15.21 depicts the Phillips curve and the indifference curves of an economy. 2001. The Phillips curve continues to shift upwards as long as there is a positive bargaining gap, caused by the low unemployment rate. In the UK the inflation rate remained stable. A positive shock to aggregate demand that reduces the unemployment rate by 2 percentage points. While a negative demand shock will increase unemployment and reduce inflation, a negative supply shock can lead to increased unemployment and inflation at the same time. 15.6 Expected inflation and the Phillips curve, 15.9 The exchange rate channel of monetary policy, 15.10 Demand shocks and demand-side policies, 15.11 Macroeconomic policy before the global financial crisis: Inflation-targeting policy, 15.12 Another reason for rising inflation at low unemployment, 16—Technological progress, employment, and living standards in the long run, 16.1 Technological progress and living standards, 16.2 The job creation and destruction process, 16.3 Job flows, worker flows, and the Beveridge curve, 16.4 Investment, firm entry, and the price-setting curve in the long run, 16.5 New technology, wages, and unemployment in the long run, 16.6 Technological change and income inequality. An aggregate demand shock that increases unemployment will reduce inflation along the Phillips curve. Workers expected a 2% real wage increase at B from their nominal pay rise of 5% (to give the real wage on the wage-setting curve), but they did not get this because firms raised their prices by 5%. Note that now, the best outcome for the policymaker is not full employment. What would you expect the central bank to do? Monetary policy in the US works mainly through the effect of changes in the interest rate on investment, particularly on new housing and consumer durables. They were due to the oil shocks of 1973–74 and 1979–80, which were associated with a rise in both unemployment and inflation to their highest levels since the Second World War (you can see the effect on inflation in Figure 13.19a and Figure 13.19b). ‘1789–2012 Presidential Elections’. The fourth column is the inflation outcome, which reflects expectations and the bargaining gap. We compare the situation over a three-year period with unemployment at two levels: 6% and 3%. However, building new plants and installing new equipment takes time. Despite a major oil shock in the 2000s, the British economy and many other economies continued to experience steady growth, low inflation and low unemployment. In Figure 15.11, the price-setting curve shifts down following the oil shock. This highlights that: Figure 15.4d It will estimate a target for the total aggregate demand. Explain why a negative bargaining gap arises. Working versions of the machine can still be found in the London Science Museum and universities around the world.2. Fiscal policy uses government spending and tax policies to influence macroeconomic conditions, including aggregate demand, employment, and inflation. In the short run there is a trade-off between inflation and unemployment, which means that policy makers could choose to reduce unemployment at a cost of higher inflation. Figure 15.16 The third cause—higher employment may result in inflation—came to light when William (Bill) Phillips, the economist, published a scatter plot of annual wage inflation and unemployment in the British economy. We need to go back to two familiar points: With these two building blocks, we can see why Friedman was right. Both higher export demand for home-built products (X) and lower demand from Australians for goods and services produced abroad (M) raise aggregate demand in the home economy. International Monetary Fund Finance & Development. Any increase in unit materials costs such as a rise in the price of oil will shift the price-setting curve down. The figure shows the inflation and unemployment combinations for the US for each year between 1960 and 2014. And up again in the early 1980s, further worsening the trade-off between unemployment and inflation. The central bank will try to achieve the inflation-stabilizing unemployment rate of 6%, as this is the labour market equilibrium. When the bargaining gap is positive, the real wage on the wage-setting curve is above the price-setting curve, and the claims of employers and owners to output per worker are inconsistent. Note that the real wage does not change, but remains on the price-setting curve. Imports and exports were shown by water being added or drained from the model. There are two important limitations, however, to the usefulness of monetary policy in stabilization: If the policy interest rate were negative, people would simply hold cash rather than put it in the bank, because they would have to pay the bank for holding their money (that’s what a negative interest rate means). UK inflation and unemployment rate (1950–2015). But how should the central bank react to a consumption boom? The monetarist school of economic thought ties the economic cycle to the credit cycle. That is to say, they do not take inflation into account. ↩, David Walton. In the event of a financial crisis, would it be preferable for the government to stabilize the economy using fiscal or monetary policy? Since many voters will prefer lower unemployment even if it comes with higher inflation, as we saw in Section 15.1, how can central banks credibly commit not to deviate from their announced inflation target? Factors such as … Inflation is due to the fact that the economy is no longer at the intersection of the two curves. Exports of British goods were cheaper in the US in November 2015 than a year before. FRED. Bank of England OBRA dataset. They typically cannot have both and face a trade-off instead. The policy mix: Fiscal and monetary policy in the US following the collapse of the tech bubble. A Phillips curve sketched through the observations in the 1960s gives a reasonably good picture of the inflation-unemployment trade-off in that decade. ↩. The equation for the real interest rate is known as the Fisher equation, named after Irving Fisher, whose physical model of the economy we saw in Unit 2. A cut in the interest rate and fiscal stimulus via tax cuts and increased government spending shifts the aggregate demand line back to its starting position. When the ballots were counted in November 1992, Clinton received almost 6 million more votes than George H. W. Bush, the incumbent president. In each case: In the Einstein in Unit 9, we explained how the price-setting curve for the economy as a whole results from the decisions of individual firms. As we saw, we can explain why people might dislike rising or volatile inflation, but most people have no reason to object to a (slowly) rising price level. A typical firm uses imported oil in the production process. Draw a labour market diagram where the economy is at labour market equilibrium with stable prices. One tool at the government’s disposal is fiscal policy. For example, if your business general follows the same economic cycle as the rest of the economy, then warning signs of an impending recession suggest that it is not a good time for you to expand your business ad you might instead be better served by building up a cash reserve against tough times ahead. ‘The Role of Monetary Policy’. If an aggregate demand shock reduces unemployment below 6%, inflation rises along the Phillips curve. A cut in Australia’s interest rate. Take the case of a slowdown in the Australian economy caused by a decline in investment demand. The markup price-setting equation says that if unit costs are $3.00 and the markup m is 10%, the price will be $3.30. 4.11 Fair farmers, self-interested students? When interest rates go down, asset prices go up. Inflation is zero in the diagram only when the unemployment rate is 6%. Another way to say this: more inflation is the opportunity cost of lower unemployment, and more unemployment is the opportunity cost of less inflation. And the inflationary process would begin. Firms raise their prices to protect their profit margins when the cost of imported oil rises. 1958. A. Economic cycle refers to the overall state of the economy going through four stages in a cyclical pattern. The resulting Phillips curve shows a positive correlation between the unemployment rate and inflation rate. Similarly, if it increases the confidence of households that they will not lose their jobs, then they may also increase their spending. Figure 15.4a In this example, unit costs rise to $4.4 + $1 = $5.4 and the price rises to P = 1.6 × $5.4 = $8.64 (a rise of 8%). 16.9 Technological change, labour markets, and trade unions, 16.10 Changes in institutions and policies, 16.11 Slower productivity growth in services, and the changing nature of work, 16.12 Wages and unemployment in the long run, 17—Capstone: The Great Depression, golden age, and global financial crisis, 17.2 The Great Depression, positive feedbacks, and aggregate demand, 17.3 Policymakers in the Great Depression, 17.4 The golden age of high growth and low unemployment, 17.5 Workers and employers in the golden age, 17.7 After stagflation: The fruits of a new policy regime, 17.8 Before the financial crisis: Households, banks, and the credit boom, 17.10 The financial crisis and the great recession, 18—Capstone: The nation and the world economy, 18.1 Globalization and deglobalization in the long run, 18.4 Specialization and the gains from trade among nations, 18.5 Specialization, factor endowments, and trade between countries, 18.6 Winners and losers from trade and specialization, 18.7 Winners and losers in the very long run and along the way, 18.9 Globalization and anti-globalization, 19.1 Inequality across the world and over time, 19.2. In this example, a bargaining gap of 2% opens up between the wage-setting curve and the post-shock price-setting curve. We use the Phillips curve and the policymaker’s indifference curves to look at shocks and policy responses. But why would it want to curtail a boom? In the late 1990s to the present, the Phillips curve is low and flat. Give a brief explanation of why the bargaining gap might have disappeared and state any other assumptions you are making. We will observe lower unemployment and higher inflation as in Phillips’ original empirical scatter plot. If the bargaining gap is 1%, prices and wages will rise by 1%. But achieving this outcome is not easy. Euros became cheaper relative to the GBP over the year, so goods imported from Europe also became cheaper. The Best Investing Strategy for Recessions, Characteristics of Recession-Proof Companies, Investors Profiting from the Global Financial Crisis. Bargaining gaps, expected inflation, and the Phillips curve. In Unit 9, we assumed that other than the firm’s own capital goods, there were no inputs other than labour and hence no costs other than wages. But while the owner of an individual firm is happy with the higher price that the marketing department can now charge, the workers are unhappy with the fall in the real wage. Figure 15.13 We would like to show you a description here but the site won’t allow us. Assume that the level of employment and the labour supply remain constant. This is the Phillips curve diagram, with inflation on the vertical axis and employment on the horizontal axis. Figure 15.17 Workers expect prices to rise by 3% and will require a nominal wage increase of 3% just to keep their real wage un­changed. What happens to the bargaining gap in each case? There are two ways that the increase in the bargaining power of workers could take place: We studied reasons for the shift in the wage-setting curve, such as improved generosity of unemployment benefits or stronger trade unions, in Unit 9. Inflation expectations and Phillips curves. While the policymaker wants to deliver both low unemployment and low inflation, the economy operates in such a way that when unemployment goes down, inflation tends to go up. What happens next? During times of expansion, investors seek to purchase companies in technology, capital goods, and basic energy. The economy emits all kinds of noisy signals and it is difficult to decide, for example, whether a downturn is a temporary blip or signifies a long-term weakness. Through this channel, a lower policy rate will raise investment by businesses and households, and a higher policy rate will lower it (see Figure 14.9). This interest rate may be more appropriate for some members than for others. A peak refers to the pinnacle point of economic growth in a business cycle before the market enters into a period of contraction. The expectations and asset price effects will shift the investment function as we saw in Figure 14.5, and the consumption function, by changing c₀ (Figure 14.11a). Another interpretation is that HR includes inflation over the past year in the wage settlement, to make up for the shortfall in the real wage that workers experienced because inflation turned out to be higher than expected. Their real wage will not have risen by 1% as they had anticipated, so they will bargain for another 1% rise. The economy then entered a quick period of growth, and in the first three months of 1981 grew at an 8.4 percent annual rate. The opportunity cost of the loan is the goods you have to give up, not the money you have to give up. High and rising inflation imposes costs on the economy. The stable inflation case is at point A with unemployment of 6% and inflation of 3%, year after year. 2015. The Phillips curve is stable over the years. Assuming m remains constant, the percentage change in the price is equal to the percentage change in total unit costs: We now divide both the numerator and the denominator of the first term on the right hand side by umc, and the second term by ulc: In words, the percentage change in P is equal to the percentage change in umc times umc’s share of unit costs, plus the percentage change in ulc times ulc’s share of unit costs. The following table shows the nominal interest rate and the annual inflation rate (the GDP deflator) of Japan in the period 1996–2015 (Source: World Bank). (Here we are setting aside the opportunity cost of the capital goods used in production that are the property of the firm owners and the basis of their profits.). Starting from a price index of 100, sketch the path of the price level for the 5 years that follow, assuming the bargaining gap remains at –1%. The price-setting curve: Wages and profits in the whole economy, 9.6 Wages, profits, and unemployment in the whole economy, 9.7 How changes in demand for goods and services affect unemployment, 9.8. The second column shows the unemployment rate. Therefore the real interest rate has been falling consistently over the period. Deflation leads the economy out of recession . Monetary policy may not be available to a country. Phillips had engineering know-how, and while studying sociology in London in 1949, he built a hydraulic machine to model the British economy. Inflation before 1950: Michael Bordo, Barry Eichengreen, Daniela Klingebiel, and Maria Soledad Martinez-Peria. Austrian economists argue that the manipulation of credit and interest rates by the central bank creates unsustainable distortions in the structure of relationships between industries and businesses which are corrected during a recession. 15.5 What happened to the Phillips curve? At the next annual round of wage-setting, the HR department is in the same position as the previous year: with continuing low unemployment, workers are disappointed with their real wage. What would the policymaker’s indifference curves look like if the policymaker cared only about low inflation? With the unemployment rate stable at 3%, the bargaining gap remains at 2%. Inflation and conflict over the pie: Stable price level at labour market equilibrium. Moreover, in an inflationary environment, firms have to update their prices more frequently than they would prefer. Draw a diagram with years on the horizontal axis and the price level on the vertical axis. Firms might find it harder to know which sector to invest in, or which crop would be better to plant (quinoa or barley, for example); individuals would find it harder to decide whether quinoa has become more expensive relative to other sources of protein. ‘A Millennium of UK Data’. In Unit 14 we explained the usual response of firms to rising capacity utilization: that they increase investment to expand their ability to meet orders. Consider an aggregate demand shock that increases unemployment. A depreciation of the home country’s exchange rate makes their exports cheaper, and imports from abroad more expensive. Economica 25 (100): p. 283. The labour market model and the Phillips curve can explain why a one-off increase in the world oil price can lead to a combination of: To do this, we show that a rise in the oil price: An increase in the oil price pushes down the price-setting curve. The economy starts in goods market equilibrium at point A. As we saw at the end of Section 15.1, the policymaker is likely to prefer low (stable) inflation to zero. UK Office for National Statistics; Ryland Thomas and Nicholas Dimsdale. The first is that politicians are elected to office, and so respond to the views of voters. Summarize your findings. Here we take a shortcut and go straight to the economy as a whole. Disinflation describes a falling inflation rate. This economy has an independent central bank with an inflation target of 2%. We can summarize the causal chain from the last period’s inflation rate to this period’s inflation rate like this: We can show the data in the table in Figure 15.8 and in the Phillips curve and labour market diagrams in Figure 15.9. Unemployment increased from 4% in 2000 to 6% in 2003, and inflation fell from 3.4% in 2000 to 1.6% in 2002. Businesses that can track the relationship between their performance and business cycles over time can plan strategically to protect themselves from approaching downturns, and position themselves to take maximum advantage of economic expansions. To see how inflation comes about in a business cycle upswing, we begin with the economy at the labour market equilibrium and with constant prices, and consider a rise in aggregate demand, which reduces unemployment below the equilibrium. The Japanese economy was one of the great success stories of the period after the Second World War. Figure 15.15 shows how the central bank could attempt to counteract a recession. ↩, A. W. Phillips. They either set this objective for themselves, or the government sets the objective for them. If the two observations in which deflation (falling prices) occurred are included in the regression in absolute values—reflecting the fact that it is changes in prices that are unpopular—then the relationship shown in the figure is stronger. Phillips’ original curve, and the model in Figure 15.4d, suggest that there is a lasting trade-off between inflation and unemployment. The real wage that employees care about is their nominal wage relative to the economy-wide level of prices, and is defined as: It is the real wage on the vertical axis in the labour market diagram in Question 15.4. The figure shows the policymaker’s indifference curves. What is the difference between inflation, deflation, and disinflation? Changes in the global economy can also cause supply shocks that trigger inflation. And experience from the late 1960s showed that inflation would carry on rising if unemployment were too low. Large price changes create uncertainty, and make it more difficult for individuals and firms to make decisions based on prices. Rather, it is the level of employment (and unemployment) that maintains labour market equilibrium, to avoid consistently rising or falling inflation. However, there is wide variation in the length of cycles, ranging from just 18 months during the peak-to-peak cycle in 1981-1982, up to the current record-long expansion that began in 2009. Inflation, expected inflation, and the bargaining gap. 1–17.
