Q

Why have economists moved away from the methods of optimal control in macroeconomic policy?

A

Economists have shifted their perspective, realizing that the economy is fundamentally different from a machine, as it involves strategic interactions among people and firms that respond to both current and expected future policies.

Q

What is a “political business cycle”?

A

It is the pattern of economic fluctuations caused by politicians manipulating economic policy to stimulate growth before elections, often followed by a downturn after elections.

44
Q

What tends to happen to output and unemployment in the medium run after a politically motivated economic expansion?

A

Output returns to its natural level, and unemployment returns to its natural rate

45
Q

Does the evidence support the idea that short-sighted voters and cynical politicians are the only reasons for steady deficits?

A

No, the evidence shows other factors like wars, crises, and economic theories also significantly impact debt levels.

46
Q

According to the “political business cycle” argument, what economic trend would we expect around election times?

A

We would expect faster growth before elections as policymakers might stimulate growth to gain voter support

47
Q

a war of attrition

A

refers to a situation where opposing parties engage in a prolonged standoff, each hoping the other will concede first

48
Q

In which context war of attrition happens ?

A
  • fiscal policy, and deficit reduction
  • episodes of hyperinflation
49
Q

Hyperinflation: definition

A

an extreme form of inflation where the prices of goods and services rise uncontrollably at very high rate

50
Q

How does a war of attrition affect fiscal policy?

A

It can delay deficit reduction as policymakers struggle to agree on how to reduce spending or increase taxes.

51
Q

What typically causes hyperinflation?

A

use of money creation to finance large budget deficits
–> support for stabilization programs = elimate this deficit

52
Q

Why are stabilization programs for hyperinflation delayed?

A

Support for these programs usually comes only after inflation severely impacts economic activity.

53
Q

The alternation of parties in power: definition

A

the shift in control of government between political parties, typically with differing priorities for economic policy

54
Q

What would be the impact of a constitutional amendment to balance the budget each year?

A

It would eliminate deficits but also remove fiscal policy as a macroeconomic tool, which is considered too high a price to pay

55
Q

Why are deficit or debt ratio limits considered better than a balanced budget requirement?

A

They offer more flexibility, but may still lack adaptability to severe economic shocks

56
Q

What problem exists with deficit or debt ratio limits in fiscal rules like the Stability and Growth Pact?

A

Such rules may lack flexibility for exceptional economic conditions and are difficult to design and enforce

57
Q

How could automatic spending cuts help manage deficits?

A

They could trigger spending cuts without direct congressional action, making cuts easier to accept and reducing political blame

58
Q

What was the Budget Enforcement Act, and when was it enacted?

A

Passed in 1990 and extended in 1993 and 1997, it introduced spending constraints and the PAYGO rule to reduce deficits in the U.S

59
Q

How did the Budget Enforcement Act manage discretionary and mandatory spending?

A

Discretionary spending was capped, allowing gradual decreases over five years, while mandatory spending was governed by PAYGO rules.

60
Q

What is the PAYGO rule?

A

It requires that any new transfer program does not increase future deficits, either by new revenue or spending cuts elsewhere

61
Q

How did the Budget Enforcement Act respond to economic recessions?

A

By focusing on spending, it allowed deficits to increase in a recession without triggering spending cuts, supporting fiscal flexibility.

62
Q

What lesson can be drawn from the Budget Enforcement Act and Stability and Growth Pact experiences?

A

Fiscal rules can assist in deficit reduction, but cannot replace the need for strong policymaker commitment

63
Q

What is the consequences of high debt ?

A

High debt requires higher future taxes and can lead to vicious cycles that complicate fiscal policy

64
Q

What happens when investors worry about a government’s ability to repay its debt?

A

Investors may demand a higher interest rate, increasing the government’s cost of servicing its debt

65
Q

How does an increase in interest rates affect a government with high debt?

A

A higher interest rate makes it necessary for the government to run a larger primary surplus to stabilize the debt

66
Q

What political consequences might arise from increasing the primary surplus to stabilize debt?

A

The necessary spending cuts or tax increases can be politically costly, leading to political uncertainty and potentially a higher risk of default

67
Q

What is the potential outcome of a government losing control of its budget due to high interest payments?

A

It may lead to a debt level that the government cannot repay, validating initial investor fears

68
Q

How do increases in debt ratios and interest rates feed into each other?

A

Higher debt ratios can lead to increased interest rates, which can further increase debt ratios, creating a vicious cycle.

69
Q

How can initial fears about government debt repayment become self-fulfilling?

A

As investors demand higher interest rates, the government’s financial situation can deteriorate, leading to an inability to repay the debt

70
Q

What are the two main outcomes when a government cannot stabilize its debt?

A

The government may either default on its debt or rely on money finance

71
Q

What are the usual consequences of default?

A

It often involves creditors taking a haircut, where they receive only a portion of what they are owed, or it may involve restructuring or rescheduling debt

72
Q

Why are governments generally reluctant to default on their debt?

A

Default can have severe economic consequences, such as bankrupting domestic banks, harming pension funds, and damaging international creditworthiness.

73
Q

Default: definition

A

the failure of a borrower, typically a government or corporation, to meet its debt obligations

74
Q

What is money finance or debt monetization?

A

It refers to the government financing itself by issuing bonds that the central bank buys, effectively increasing the money supply without directly printing money.

75
Q

How is seignorage defined in the context of money finance?

A

real revenue of the government through money creation

76
Q

seignorage: calculation

A

∆H/P = ∆H/H x H/P

77
Q

What happens to inflation when a government relies heavily on money finance?

A

Increased money supply typically leads to higher inflation, which reduces the real demand for money and can create a vicious cycle requiring even more money creation

78
Q

What can result from excessive money growth and inflation?

A

It can lead to hyperinflation

79
Q

How do high inflation rates affect a government’s revenue needs?

A

Higher inflation diminishes the tax base, prompting the government to increase the rate of money growth to maintain revenue levels.

80
Q

What are the four main costs of inflation identified by economists?

A
  1. Shoe-leather costs
  2. Tax distortions
  3. Money illusion
  4. Inflation variabilit
81
Q

What are “shoe-leather costs”?

A

refer to the economic costs incurred by individuals and businesses due to the need to manage their money holdings in response to inflation
–> need more cash

81
Q

How do shoe-leather costs change during periods of hyperinflation?

A

They become quite large, but their importance in moderate inflation is limited

81
Q

How does inflation impact capital gains taxation?

A

Higher inflation rates lead to higher nominal capital gains taxes, even if real gains are zero

81
Q

Bracket creep

A

refers to a situation in which taxpayers are pushed into higher income tax brackets due to inflation or nominal wage increases, even when their real income (adjusted for inflation) has not increased

82
Q

How could the capital gains tax issue be resolved in relation to inflation?

A

By indexing the purchase price to the price level to adjust for inflation before calculating capital gains

82
Q

What is “money illusion”?

A

The tendency for people to misjudge nominal versus real changes in incomes and interest rates due to inflation

82
Q

How can inflation lead to incorrect economic decisions?

A

Inflation complicates simple comparisons and calculations regarding income and asset values, making decision-making more difficult

82
Q

Why do some argue that inflation’s costs are partly due to a poorly designed tax system?

A

Because the interactions between taxation and inflation lead to distortions that could be mitigated by better tax indexing

83
Q

What is inflation variability?

A

Inflation variability refers to the fluctuations in inflation rates over time, which can create uncertainty about future economic conditions

84
Q

Why does inflation variability make financial assets riskier?

A

Financial assets like bonds, which promise fixed nominal payments, become riskier when inflation is variable because the real value of those payments can fluctuate unpredictably

85
Q

How does constant inflation affect the valuation of a bond?

A

With constant inflation, both the nominal and real values of a bond’s future payments are known with certainty, making it easier to calculate their future worth

86
Q

What happens to the real value of a bond with variable inflation?

A

The real value of a bond’s future payments becomes uncertain with variable inflation, making it harder to predict its future purchasing power

87
Q

What are indexed bonds?

A

bonds that adjust their nominal payments based on inflation, protecting holders from the risks associated with inflation variability.

88
Q

What solution can help mitigate the risks of inflation variability?

A

Issuing indexed bonds can help protect investors from the uncertainty of inflation, ensuring the real value of their returns remains stable

89
Q

What are the three benefits of inflation?

A

1) Seignorage
2) Facilitating real wage adjustments through money illusion,
3) Allowing for negative real interest rates in macroeconomic policy.

90
Q

Why Seignorage positif ?

A

Seignorage is positive for inflation because it enables governments to finance spending through money creation, reducing the need for taxes or borrowing and potentially stimulating economic activity by encouraging spending and lowering the real burden of debt.

91
Q

What is the role of money illusion in inflation?

A

Money illusion can lead people to accept real wage cuts more readily when inflation is positive, facilitating necessary wage adjustments in the economy.

92
Q

How does higher inflation impact the zero lower bound?

A

Higher inflation reduces the likelihood of hitting the zero lower bound, allowing central banks more flexibility to lower nominal interest rates during economic downturns

93
Q

What is the impact of inflation on monetary policy during a recession?

A

In a high-inflation economy, central banks can lower nominal interest rates significantly to stimulate spending, whereas low-inflation economies have limited capacity to do so.

94
Q

What is the current inflation target for most advanced economies?

A

The typical inflation target for central banks in advanced economies is around 2%

95
Q

What are the arguments for and against a 0% inflation target?

A

dvocates of 0% inflation argue for price stability and simplicity in decision-making, while opponents believe it limits the central bank’s ability to respond to economic shocks.

96
Q

What are the arguments for a higher inflation target, such as 4%?

A

A higher target can prevent falling into a liquidity trap and provide more room for monetary policy during economic downturns

97
Q

What does the Lucas critique state about empirical associations between economic variables?

A

Empirical associations cannot be assumed to be constant over time; they depend on expectations and the behavior of decision-makers

98
Q

Why is modeling economic decisions important in the context of the Lucas critique?

A

Modeling economic decisions is essential to capture how empirical relationships depend on expectations and the decisions of private households, firms, and central banks.

99
Q

What application of the Lucas critique explains the disappearance of the Phillips curve trade-off?

A

The critique shows that the stable empirical relationship between inflation and unemployment can vanish when expectations change, necessitating consideration of these changes in expectations

100
Q

What issue arises from the interaction of expectations with monetary policy according to the Lucas critique?

A

The critique highlights the inflation bias and time inconsistency problem in monetary policy, where policymakers may not adhere to their announced policies due to changing expectations.

101
Q

How does the Lucas critique affect the understanding of monetary policy’s effectiveness?

A

It suggests that traditional models may mislead policymakers, as they fail to account for how expectations can alter the outcomes of monetary policy interventions.
