07 Government Flashcards
Government and institutions affect:
- Accumulation
- Public spending (e.g., roads)
- Incentives
- Accumulation of human capita, through
- Public spending, e.g. education & health services
- Incentives
- Political uncertainty
- Population growth (e.g. China’s one-child policy)
- Technological change (public spending on R&D, incentives, patent system)
- Efficiency (tax system, regulation, security, administration of laws)
Why do we need a government for encouraging growth?
- Correct market failure
- Redistribution of income
Market failure
Market failure occurs when the market does not produce an efficient outcome. Due to:
- Public goods:
- E.g. defence, infrastructure, rule of law, currency.
- Externalities:
- E.g. R&D, pollution.
- Monopoly:
- E.g. electricity transmission.
- Coordination failures:
- When a group of firms could achieve a more desirable equilibrium but fail to because they do not coordinate their decision making.
- E.g. car producers unwilling to invest bc of uncertainty about supply of car parts; supplier industry unwilling to invest bc of uncertainty about demand.
Redistribution
High- to low-income
Between generations
But does it help growth?
Does redistribution help growth?
- Lower inequality is correlated with faster growth.
- Redistribution is correlated with higher growth (IMF, 2014).
- Inequality affects physical and human capital accumulation.
- More: Weil Chapter 13.
The case against government intervention
- In theory government regulation can eliminate market failure.
- In practice, potential for government failure:
- When government intervention causes a more inefficient allocation of resources than would occur without that intervention.
- E.g. inefficiency in state-run firms (lack of incentives such as profits).
- What’s the lowest cost: Inefficiency of monopoly or inefficiency of goverment regulation?
- Difficult to set the right tax/subsidy to internalize externalities.
- Redistribution: Trade-off between redistribution and efficiency?
- Efficiency loss by raising taxes.
- Benefits from greater degree of equality.
- Arthur Okun (1975) “Equality and Efficiency: The Big Tradeoff”

Empirics: How the government affects growth
- Rule of law
- The tax system
- Economic planning and policy
- Absence of government (conflict)
How the government affects growth:
Rule of law
- Essential public good.
- Existence of courts that enforce contracts.
- Patent laws.
- Existence of courts and police to enforce ownership.
- Lack of rule of law a major reason for low growth and underdevelopment for many countries.
- “The inability of societies to develop effective, low-cost enforcement contracts is the most important source of both historical stagnation and contemporary underdevelopment in the Third World” (Nobel price laureate Douglass North, 1993).
- Impedes factor accumulation and inefficiency.
How the government affects growth:
The tax system
- High growth in spending the last century.
- Richer countries require more complex regulation.
- Wagner’s law: The income elasticity for public goods > 1, e.g., health.
Wagner’s law: The income elasticity for public goods ____
Wagner’s law: The income elasticity for public goods > 1
Government spending as a percentage of GDP (1880 to 2010)
2009: Average spending among OECD countries 47% of GDP
Efficiency loss: Recent estimate of deadweight loss is __ in lost output for $1 in government spending (Feldstein, 1997)
Efficiency loss: Recent estimate of deadweight loss is $1 in lost output for $1 in government spending (Feldstein, 1997)
Deadweight loss
- Some transactions will not take place (transactions that would benefit buyers and sellers) => lower consumer and producer surplus
- Very high tax rate yields zero tax revenue and zero transactions
Correlation between taxes and income
No negative correlation between taxes and income - in fact it’s positive. Governments tend to use tax revenue wisely - infrastructure, education, etc.
