Why does government exist?

Three main rationales for public sector action:

    • Market failure (consumer ignorance of mortgages, pollution)
    • Externalities (public goods and bads)
    • Distributional unfairness (poverty)
  • Market failure typically evokes a regulatory response (e.g., consumer education, fair lending laws, securities regulation).
  • Public goods encourage government to supplement private sector provision of a good or services (e.g., subsidization of crop insurance, subsidization of vaccines, public education).
  • Distributional fairness can result in regulatory, direct provision of a service, or direct cash transfer
    • Laws regarding usury, anti-discrimination legislation
    • Public housing
    • National child benefit, progressive tax, GST rebate for lower income households
definition of government initiatives
Definition of government initiatives
  • Social marketing to promote a goal (articulation of goal or intent; guidance on preferred behaviour)
  • Expenditures on goods and services
    • Direct resource commitments on goods (public housing, vaccination)
    • Direct resource commitments on services (consumer information, training)
    • Tax expenditures (tax deductions and credits awarded to citizens and businesses to behave, spend, invest, etc.)
    • Grants/contributions/contracts to third parties to perform services
  • Legislation is a general framework for how citizens conduct themselves (smoking bans, criminal code) and requires political assent.
  • Regulation modifies elements of legislation (changes to the speed limit) and can be completed by administrative fiat.
information failure
Information Failure
  • Moral hazard
    • Market participants alter their behaviour in response to the divergence of public and private costs
    • Taxes/subsidies cause market participants to purchase/sell less/more than would have occurred with prices equal to the marginal cost
  • Asymmetry of information
    • Sellers are typically more informed than buyers
    • Prisoners paradox - information lack produces sub-optimal outcomes
  • Uncertainty about other players reactions causes poor decisions
    • Nash equilibrium exists when I account for your probable reaction to my choices. Equilibrium exists when we have all adjusted and readjusted to each others choices/decisions.

  • Equity/fairness
  • Pareto efficient outcomes are not often (never?) “fair” Recent research shows that ideas of equality and fair distribution become settled for most people by the age of 10*. Strong evidence exists that humans develop altruistic instincts early.

  • Efficiency is not the only goal
  • One can judge a society by how it takes care of its weakest.
  • Daniel Moynihan (US Senate)
value for money can be defined as
Value for money can be defined as:
  • Relevance – Are we doing the right thing?
    • Program addresses a demonstrable need, is appropriate to the federal government, and is responsive to Canadians
  • Performance – Are we achieving value?
    • Economy: Are taxpayer resources well-utilized?
    • Efficiency: Are program outputs (services and products) achieved in an affordable manner?
    • Effectiveness: To what extent have program objectives been achieved? That is, what results were produced? Are the costs of achieving program outcomes minimized?

relevance
Relevance

Relevance (need) emerges in two ways:

    • Consumers validate the demand for goods and services in the market place (private goods).
    • Government determines needs that the public sector may legitimately provide (government provision of private and public goods).
  • Private and public goods
    • Private goods allow all the benefits/costs to be consumed (internalized) by the consumer.
    • Public goods have external benefits and costs that cannot be internalized (i.e., externalities exist); there is no incentive for private provision.
  • Merit goods/services are offered by government or charities based on ethical concepts (e.g., National Child Benefit).
measuring the value for money
Measuring the value for money

Two requirements:

  • Measure the “bang”
  • Measure the “bucks”

Benefit cost = “bang per buck”

Cost - benefit = “buck per bang”

Cost-effectiveness analysis – What is the cost of specific outcomes arising from different interventions that produce that outcome?

Cost-utility analysis – What is the perceived value of the outcomes relative to their costs?

Cost-benefit analysis – What is the value of all outcomes in relation to all costs?
