5 Disadvantages of using GDP to measure econ. welfare?

A

✅ Income Distribution: Doesn’t take into account inequality, e.g. China has massive GDP but extremely high inequality.
✅ Externalities: Ignores the -ve externalities of g/s that contribute to GDP. Not a reliable indicator of social welfare. e.g. plastic bag production
✅ Informal economy transactions not counted: e.g. Roadside stalls, unpaid care, criminal activity.
✅ Service-driven econ value not fully realised: e.g. Google, doesn’t take into account the value added to the economy.
Communication / searching for information has immense value, but doesn’t directly contribute to the econ.
✅ Composition of Output - Doesn’t tell us what is being produced and who it benefits.

Q

Why do Neoclassical economists argue the LRAS curve is straight? (free market LRAS)

✅ Long-run decline ⬇️D in a whole industry => ⬇️ unemployment because of int. comp.
✅ Evolving structure of an economy => occupational immobility of labour => unemployment . eg. automation of factory jobs but creation of new jobs in robot engineers, but laid off factory worker cannot easily be trained to be a robot engineer.

- Age Disparities
- Ethnic Differences
- Gender Disparities
✅ This means that government policy could be more efficient and less broad

87
Q

118
Q

Explain how ⬇️AD => cyclical unemp.

A

✅ ⬇️ in a component of AD => ⬇️ in AD, ceteris paribus => AD will shift to the left (draw a diagram) => movement along the AS curve + new equilibrium => ⬇️ in output => When firms produces ⬇️ output, they require ⬇️ inputs (i.e. workers) => ⬆️ in cyclical unemp.

119
Q

Why ⬆️ $ levels => ⬆️ AS?

A

✅⬆️ profitable to supply, encouraging firms to produce more ( and incentivising more firms to enter the market) ✅⬆️$ levels => being cost efficient less relevant bc can have ⬆️ costs of production + still make profits => ⬆️ ‘inefficient producers’ can enter a market.

120
Q

What does the Keynesians’s belief of long-run wage rigidity mean for unemp.?

A

✅ Unemployment can persist bc imperfections in labour market => prevent wage rates falling to eliminate excess supply in labour market.

121
Q

Why do Keynesian economists believe about emp in the long run?

128
Q

A

✅ Firms invest to meet future demand.
✅ They need to know the future health of the econ. to plan for expansion.
✅ Optimistic about future => confidence to buy more => AD shift right.

130
Q

✅ $ of making staff redundant

134
Q

Why do Keynesian economists argue LRAS curve is curvy? (L-shape)

A

✅ Even in the long run, the economy can be operating below full capacity because:
✅ Sticky prices - firms don’t instantly change their prices to changes in the economy, e.g. because wages are set in pretty long-term contracts + also menu costs
✅ -ve multiplier effect - someone loses their job, doesn’t spend as much, someone else doesn’t get $, on and on.
✅ Paradox of thrift - The effect of a recession is that people will lose confidence + save ⬆️ in long run.

  • Int/r
  • Level of consumer indebtedness
  • Wealth
146

  • Overall macroeconomic environment
  • Income and its growth (Firms forced to increase capacity to meet increased D for g/s.
147
Q

What is crowding-out effect

A
  • Criticism of Keynesian expansionary fiscal policy (government)
  • Keynesians say expansionary fiscal policy good because multiplier effect.
  • But negative multiplier effect must be applied too - taxing people and taking money away from them, which they could’ve spent on other goods.
148
Q

Evaluation of fiscal policy

A
  • time lags (time between economy entering a recession and the time the policy has an impact)
  • has expansionary bias: politicians want to spend more to increase popularity => may widen trade deficit: increased incomes increases imports + decreases exports as exports become less competitive
  • expansionary crowds out private investment, making it less effective. Increased government borrowing => increased int/r on gov bonds => increased int/r in other parts of the economy => decreased consumption
149
Q

Evaluation of monetary policy

A
  • Spending doesn’t only depend on int/r. Consumer/business confidence important determiner of responsiveness to int/r change
  • natural limitations: cannot have -ve int/r
  • time lags lead to uncertainty
150
Q

What are supply-side policies

A
  • aim to shift AS rightwards.

- eg. improving education, health services, infrastructure

151
Q

Examples of pro-market supply-side policies

A
  • making labour market more flexible
  • increase competition so economy benefits from increased efficiency
  • decreasing tax rates to incentivise working
152
Q

Criticisms of pro-market supply policies, eg.

  • making labour market more flexible
  • increase competition so economy benefits from increased efficiency
  • decreasing tax rates to incentivise working
A
  • tax cuts may increase inequality
  • privatisation leads to unemployment in the short run
  • deregulation is usually unsuccessful in raising competition and lowering prices, eg. 1990s energy crisis. Deregulation of utility companies created a private monopoly with no incentive to lower prices.
153
Q

A
  • subsidised low interest loans
  • lower tax rates
  • protection from foreign competition
154
Q

155
Q

Policies to deal with cost-push inflation

A
  • increase int/r (monetary)
156

157
Q

What does the long run Philips Curve look like

A
  • straight line
158
Q

What does the long run Philips Curve (LRPC) look like

A
  • straight line at the natural/equilibrium rate of unemployment
159
Q

Policies to lower structural unemployment?

A
  • training and retraining programs
  • eliminating min. wage laws
  • reforming education to produce people who are creative and willing to learn, and give people skills such as use of technology that can be widely applied
160
Q

Problems with policies trying to reduce structural unemployment

A
  • decreasing worker protection (eg. min wage) => social unrest => hinders growth and increases inequality => slows economic development
  • expansionary demand-side policies ineffective at lowering structural unemployment as in the long term demand-side policies only increase inflation, any decrease in unemployment will be short-term
161
Q

Why should governments not try to lower unemployment below natural rate?

A
  • LRPC is vertical => any expansionary policies to move SRPC rightwards would only succeed temporarily and just cause higher inflation
162
Q

Benefits of equitable income distribution

A
  • poorer people have a higher propensity to consume than the rich => redistribution increases AD especially for inferior goods
  • Poor can access crucial resources, eg. education and healthcare => productivity of human capital increases + quality of life increases => AS shifts rightwards => development and economic growth
  • Fewer social tensions => people more willing and able to save more + decrease uncertainty for investors => higher rates of investment by banks and investors=> economic growth.
163
Q

What does Laffer Curve look like and why slopes downward after a while?

A
  • after a while higher tax rates create disincentives for people to work and invest.
  • at 100% tax rate, zero tax revenues as no reward to individuals for any productive effort.
164
Q
