  • ECONOMIC POLICIES TRY TO HELP COUNTRIES ENJOY STRONG AND STABLE GROWTH IN INCOMES

    Macroeconomics is the study of income

    3

  • What is macro about?

    • Macroeconomics is the study of income.– Why do incomes vary over time?– Why do they differ across countries?– Why do they differ among people?

    • If we try to answer all these questions at the same time, we may not be any to answer any. So we take it one step at a time.

    • First, we ignore variation among people within a country. We pretend that everyone within a country makes the average income of that country.

    • Second, we make a distinction between short-run changes in income and long-run changes in income.

    4

  • Income: Long Run vs. Short Run

    • The long-run component of income is called the trend or potential income.

    • Fluctuations around the trend or potential are the short-run component of income.

    • When income is above trend, the economy is said to be in the boom phase of the cycle or in an expansion; when income trend, the economy is experiencing a slowdown or a slump.

    • Output gap: the difference between income and its trend (or potential)– Negative output gap: income is below trend – Positive output gap: income is above trend

    5

  • Main indicator of interest

    Eye of the bird: Real income per person (a.k.a. real GDP per capita, real output per capita)

    Other indicators:Unemployment rateInflation rateInterest rateExchange rate

    6

  • U.S. real income per person (a.k.a. US real GDP per capita)

    7

  • Trend vs. cycles in real GDP

    There are two main components of real GDP (or of real GDP per capita)

    • The first is the trend. The trend is generally upward and reflects technological progress and ‘factor accumulation’

    • The second component is the business cycle (or cyclical fluctuations). This refers to the movements around the trend.

    – When real GDP is above its long-run trend, the economy is said to be in the boom phase of the cycle or in an expansion; when real GDP is below its long-run trend, the economy is experiencing a slowdown or a slump.

    – Output gap (or GDP Gap): the difference between real GDP and its long-run trend

    • When output is about its long-run trend, the GDP gap is positive• When output is below its long-run trend, the GDP gap in negative

  • Two short-cuts to understanding macro

    • Comparing micro and macro– Fish demand and supply– Aggregate demand and aggregate supply

    • Parable of Robinson Crusoe– Circular flow of income– Aggregate demand and aggregate supply

    12

  • National income identityThe expenditure approach to measuring GDP• Measures total spending on final goods and

    services produced within a nation during a specified period of time

    • Four main categories of spending: consumption (C), investment (I), government purchases of goods and services (G), and net exports (NX)

    • Y = C + I + G + NX

  • A General View of Growth• Y = F (Policies, Institutions, Geography, Shocks or Something Else)

    • Policies – Macroeconomic Policies – Openness to trade

    • Institutions– Extent of Rule of Law; Protection of Property Rights; Quality of Bureaucracy

    • Geography; – Sachs: the “bad latitude” problem; Jared Diamond’s “guns, germs and steel”

    • Shocks– Terms of trade shocks – Political conflict– Financial crises

    • Something Else– Foreign Aid?– Resource Curse?– Expectations/Motivation?

  • Basic Facts About Income Inequality

    23

  • ‘Global Inequality’ (“Imagine there’s no countries”:Evolution of the World Distribution of Income

    24

  • Inclusive Growth

    25

    “A unifying framework for all this [new] work can be summarized in two words: Inclusive growth. We want growth, but we also want to make sure:

    • that people have jobs—this is the basis for people to feel included in society and to have a sense of dignity;

    • that women and men have equal opportunities to participate in the economy—hence our focus on gender;

    • that the poor and the middle class share in the prosperity of a country—hence the work on inequality and shared prosperity;

    • that, as happens, for instance when countries discover natural resources, wealth is not captured by a few—this is why we worry about corruption and governance;

    • that there is financial inclusion—which makes a difference in investment, food security and health outcomes; and

    • that growth is shared just not among this generation but with future generations—hence our work on building resilience to climate change and natural disasters.”

  • Unemployment

    • Two components of unemployment rate– Cyclical unemployment – related to the business cycle

    – Natural rate of unemployment – the unemployment that would prevail even in the absence of business cycles (even at “full-employment’)

    • In a slump, the actual unemployment rate rises above the natural rate; cyclical unemployment is high

    • In a boom, the actual unemployment rate falls below the natural rate; cyclical unemployment is low.

  • UNDERSTANDING CYCLICALRELATIONSHIPS

    28

  • List of Figures (see Data_National Sheet in ‘Okun’ Database)

    • Real Income– Plot of raw data– Plot of logged data and trend (HP)– Plot of cycle component (HP)– Plot of logged data, trend and cycle (HP)

    • Unemployment Rate– Plot of raw data– of data and trend (HP)– Plot of cycle component (HP)– Plot of data, trend and cycle (HP)– Cycle components between U and Y

    • Unemployment Rate– Plot of data and trend (average)– Plot of cycle component (average)– Plot of data, trend and cycle (average)– Cycle components between U (average) and Y (HP)

  • Real Per Capita Income

  • Real Income – HP Trend

  • Real Income – Cycle (after removing HP trend)

  • Real Income – Trend and Cycle

  • Unemployment Rate

  • Unemployment Rate – HP Trend

  • Unemployment Rate – Cycle (after removing HP trend)

  • Unemployment Rate – Trend and Cycle

  • Cyclical Components of Output (Income) and Unemployment

  • Unemployment RateTrend = Sample Average

  • Unemployment Rate – Cycle (Deviations around Sample Average)

  • Unemployment Rate – Trend and Cycle

  • Cyclical Components –Real Income (HP), UR (Average)

  • Okun’s Law (“Levels” or “Gap” version)

    43

    ut – ut* = β (ln yt – ln yt *) + εt β < 0

    u = unemployment rateu* = natural rate of unemployment

    ln y = natural log of output (or output per capita)ln y* = natural log of potential output (or output per

    capita)

    We measure ut* and yt * with HP filter (“lambda” = 100).

  • Okun’s Law(“Changes version”)

    44

    Δut = α + β yt + ωt

    Δu = change in unemployment rate(i.e. Δut = ut – ut-1 )

    y = growth rate of real GDP

    • The “changes” version follows from the “levels” or “gap” version under certain assumptions (for example, if u * and Δy* are constant)

  • Estimates of Okun’s Law

    45

  • The flattening of the “Phillips Curve”

  • Many different interest rates

    • For this lecture:– Policy interest rate (can be “set” by central bank)– Short-term interest rate– Long-term interest rate

    • Each of these interest rates can be decomposed into a part that is “real” and a part due to “expected inflation”

    • An assumption we make is that by changing the policy interest rate the central bank can influence other interest rates

    • The relationship among short-term and long-term interest rates is called the ‘yield curve’ or the ‘term structure of interest rates’

    50

  • 51

  • How Should Central Banks Set the Policy Rate?The Taylor Rule

    • The first ‘2’ in the equation is the neutral (long-run) real interest rate (assumed to be 2 percent)

    • The second ‘2’ in the equation is the inflation target (assumed to be 2 percent)• The two ‘0.5’ numbers are values that held for the U.S. in the 1980s and 1990s. They can

    be different over other periods, and can differ by country.

  • Taylor Rule (continued)

    • If p = 2 and output is at potential, then monetary policy targets the real policy rate at 2% (and therefore the nominal policy rate is 4%).

    • For each percentage point increase in p, monetary policy should be ‘tightened’ by raising the real policy rate by 0.5 percentage points.

    • For each percentage point that GDP falls below potential, monetary policy should be ‘eased’ by reducing the real policy rate by 0.5 percentage points.

    When the Fed Wants to “Loosen”

    Fed buys T-billsfrom banks

    Fed pays for the T-bills by writing a cheque: injecting liquidity

    Banks now have more cash than they want to hold

    Banks that want to borrow from other banks can do so at a lower fed funds rate money is cheap

    Fed injects liquidity until fed funds ratehas fallen to the Fed’s set “target”

  • Transition from Short Run to Long Run (1)

    • Interest rates and money supply

    – Raising policy interest rates is similar to curbing growth of money supply.

    – Lowering policy interest rates is similar to raising the growth rate of the money supply.

    • In the short run, the central bank lowers policy interest rates (i.e. raises the growth rate of the money supply) to stimulate the economy (bring output back to trend; close the output gap)

    • But it lowering policy interest rates stimulates the economy, shouldn’t the central bank always keep interest rates low?

    56

  • Transition from Short Run to Long Run (2)

    • ‘Good’ scenario:– Central bank has lowered rates because the economy is in

    a slump (output gap is large). In this case, inflation may not go up much; plus, some stimulus can be justified even if inflation does go up a bit

    – The central bank has credibility, that is, people expect it to keep its (medium- to long-run) inflation target. This means that people expect that interest rates will be raised back to neutral once the output gap has closed. Hence, inflation expectations remain anchored.

    57

  • Transition from Short Run to Long Run (3)• ‘Bad’ scenario(s):

    – Wrong reasons: Central bank has lowered rates even though the economy is not in a slump (output gap is zero). Or, the central bank may have made a mistake about the size of the output gap. In these cases, inflation may go up (and the stimulus cannot be justified on the grounds that it is helping the economy recover from a slump)

    – Right reasons, poor credibility: Central bank may have lowered reasons for the right reasons (economy is indeed in a slump) but it has poor credibility. That is, people expect it will not keep to (or have difficulty keeping to) its medium- to long-run inflation target. This means that people expect that interest rates will not be raised back to neutral once the output gap has closed. Hence, inflation expectations can get unanchored.

    – Wrong reasons, poor credibility: Worse case scenario – inflation may kick up because central bank has intervened at the wrong time; and problem is compounded as inflation expectations get unanchored.

  • The Quantity Theory of Money

    Key

    π inflation rate

    ∆M/M growth rate of money supply

    ∆Y/Y growth rate of output (real GDP)

    60

    Normal economic growth requires a certain amount of money supply growth to facilitate growth in transactions. Money growth in excess of this amount leads to inflation. Inflation is “too much money chasing too few goods”

    [Note: we’re simplifying by assuming that the ‘velocity of money’ is constant.]

    As we have learnt, in the long-run, ∆Y/Y (growth rate of real GDP) depends on growth in inputs and on technological progress.

    Hence, the Quantity Theory of Money predicts a long-run one-for-one relation between changes in the money growth rate and changes in the inflation rate.

    Note: During hyperinflations, the quantity theory of money can hold even in the short run

  • Aggregate Demand and Aggregate Supply:Effects of a Permanent Monetary Expansion

    A monetary expansion leads to an increase in output in the short run but has no effect on output in the medium run.

    The difference between Y and Ynsets in motion the adjustment of price expectations.

    In the medium run, the AS curve shifts to AS’’ and the economy returns to equilibrium at Yn.

    The increase in prices is proportional to the increase in the nominal money stock.

    65

    What is it?•π ≥ 50%

    per month

    What causes it?• Excessive money

    supply growth.

    Does that work?• Only for a short time.

    • Because money ceases to function as a store of value, and may not serve its other functions (unit of account, medium of exchange), people start conducting transactions with barter or a stable foreign currency.

    • Because people are no longer willing to subject themselves to the “inflation tax,” it ceases to be a source of revenue for the government.

    How is it stopped?• Proximate step: stop printing

    money.

    • At a more fundamental level: it requires a credible announcement of government fiscal reform (i.e. cuts in government spending, increases in tax revenue, new sources of borrowing or some combination of all three) and follow-through.

  • MONETARY POLICY IN OPEN ECONOMIES: THE IMPOSSIBLE TRINITY

  • Interest Rate Parity

    • If domestic and foreign assets are considered perfect substitutes, then we expect interest parity to hold on average:rt –rwt = (Xet+1 – Xt)/Xt

    • That is, the interest rate differential between the domestic (Rt ) and foreign interest rate (rwt ) should be zero, unless the market expects changes in the exchange rate. – In practice, interest rate differentials fail to predict large swings in actual

    exchange rates and even fail to predict which direction actual exchange rates change. Why?

    • It could be because domestic and foreign assets are imperfect substitutes. Changes in risk premiums (ρt ) may drive deviations from interest rate parityrt –rwt = (Xet+1 – Xt)/Xt + ρt

  • Example of Interest Rate Parity

    We should expect that interest rates on offshore currency deposits and those on domestic currency deposits within a country should be the same if

    – the two types of deposits are treated as perfect substitutes,

    – assets can flow freely across borders and – international capital markets are able to quickly and easily

    transmit information about any differences in rates.

  • Interest Rate Parity (IRP) and Monetary Policy Choices

    IRP imposes limits on central bank’s monetary independence.

    Why?

    • Assume capital can flow in unlimited amounts between domestic and foreign country.

    • Suppose now the domestic central bank were to try to keep exchange rates steady.

    • At the same time, suppose also that it tries to adjust interest rates (say upwards) in order to attain a separate inflation target.

    • Under fully-integrated capital markets, higher domestic interest rates ⇒ large capitalinflow into the domestic economy.

    • Capital flows in ⇒ the value of the domestic currency will have to go up versus the foreign currency—i.e., appreciation of the domestic currency.

    • So the exchange rate cannot be held steady if the interest rate objective takes primacy.

  • • Suppose now the central bank wants to keep its currency from appreciating.

    • To prevent appreciation it must either inject more domestic currency into the market directly, or buy up foreign currency with domestic currency.

    • Either way, the domestic currency it issues or pays out is new money ⇒ expansion in domestic liquidity

    • Expansion in domestic liquidity ⇒ interest rate falls

    • So the interest rate target cannot be achieved if the fixed exchange rate takes primacy.

    IRP and Monetary Policy Choices (continued)

  • Conclusion: One of the three must go. Either

    • A central bank must give up trying to maintain stability in exchange rates and allow the currency to be determined by the market forces that work through arbitrage, or

    • A central bank must give up its independence in setting domestic interest rates; that is, it must align its domestic objectives with the objective of keeping exchange rates stable, or

    • Something has to be done to limit capital flows and break the arbitrage that ties together exchange rates and interest rates.

  • Breaking the Arbitrage that Ties Interest Rates and Exchange Rates:

    • The ability to conduct full arbitrage between local and global capital markets depends on the degree to which capital is allowed to flow between the two sets of markets—the degree of capital market integration or linkage between domestic and global markets.

    • The degree of capital market integration often depends on the level of development and sophistication of local financial markets and institutions. But it can also be a policy choice

  • Degree of Capital Market Integration:

    “Full” or complete capital market integration: Few or no legal restrictions or natural market barriers on capital flows between domestic and global capital markets, particularly on currency-related transactions.

    ⇒No limit on volume of capital flows between markets. Convertibility of currency on capital account (not just current account).

    ⇒Feasible to conduct unlimited arbitrage whenever it makes sense to.

  • Degree of Capital Market Integration:Less than complete capital market integration:

    Significant capital or exchange controls limit the volume of capital that can flow between domestic and global markets.

    ⇒Capital markets are segmented and arbitrage between from one market to another is expensive or impossible.

  • “Impossible Trinity”

    “Impossible Trinity” or Policy Trilemma–The following three things are incompatible:

    Fully integrated capital markets (which would require interest rate parity)

    Independent or autonomous monetary policy (i.e., CB can target policy interest rates, as in the Taylor’s Rule we discussed )

    Fixed (“stable”) exchange rates (x)
