Title: The End of LaissezFaire: Macroeconomic Instability and Microeconomic Inefficiency


1
The End of Laissez-Faire Macroeconomic
Instability and Microeconomic Inefficiency
  • Peter J. Boettke
  • Econ 881/Spring 2005
  • 14 February

2
Historical Context
  • Turn of the Century America
  • Poverty Amidst Plenty
  • inequality
  • Progressive Era Legislation
  • Antitrust policy
  • cut-throat competition
  • Pure Food and Drug Act
  • consumer protection from impure products
  • Working Conditions
  • Exploitation
  • WWI
  • Interpretation of Imperialism and War Socialism
  • Capitalism as cause, socialism as solution
  • Great Depression
  • Aggregate demand failure (underconsumption)
  • New Deal Legislation
  • Putting people to work and giving them hope
  • WWII
  • Greatest Generation

3
Importance of the Soviet Union
  • Socialism as a Viable Alternative
  • No monopolistic exploitation and now crisis such
    as the Great Depression
  • Socialism tamed by Democracy Interventionism
  • Nothing in the idea of socialist planning is
    inconsistent with democratic freedom in fact, in
    the 1930s it was often argued that socialism was
    the fulfillment of democracy in economic life.
  • Socialist Reality
  • Orwell --- Animal Farm --- all animals are
    equal, just some animals are more equal than
    others

4
Why No Socialism in the US?
  • Check your premise
  • 60 of GDP during WWII was government it is hard
    to argue that your country is not socialist.
  • Nationalization vs. Regulation
  • Regulatory apparatus was established to control
    capitalist excess
  • Union power to eliminate exploitation

See Samuelson, Economics, p. 152-154 185ff,
esp., 186.

The Economics of Over Production and Under
Consumption
  • Overproduction --- Samuelson, Economics, p. 4.
  • Command and Control for Public Administration ---
    ibid, p. 5.
  • The Fallacy of Composition --- ibid., p. 9.
  • The System as a whole --- ibid, p. 9.
  • What is true of one of kind of world may be
    false of another. Similarly, for the modern world
    of unemployment, the conclusions of the classical
    or Euclidean economics may not be at all
    applicable. The important hard kernel of truth
    in the older economics of full employment can
    then be separated from the chaff of misleading
    applications. Moreover, as we shall see later, if
    modern economics does its task well so that
    widespread unemployment is substantially banished
    from democratic societies, then its (i.e.,
    national income accounting) importance will
    wither away and the traditional economics (whose
    concern is wise allocation of fully employed
    resources) will really come into its own almost
    for the first time. Samuelson, Economics, p. 10.

Income Expenditure Keynesianism
  • National Income Accounting
  • Circular Flow and Avoiding Double Counting
  • Final Goods Prices (e.g., bread, flour, wheat)
  • Aggregate Demand Failure and Depression Economics
  • Full employment level of income
  • Savings and Investment
  • Leakage in the system due to liquidity traps,
    etc.
  • Coordination failure between savers and investors

7
The Determination of Price By Supply and Demand
  • The Logic of Market Clearing
  • Non-economic considerations for blocking the
    price system
  • The Structure of Perfect Competition
  • Numerous buys and sellers and no control over
    price
  • Monopoly
  • Complete control over price except as set by
    government regulation
  • Imperfect and Monopolistic Competition
  • Some control over price

See Samuelson, Economics, p. 492.

Welfare Economics Market Efficiency and Market
Failure
  • Character of General Competitive Equilibrium
  • Exchange Efficiency
  • Production Efficiency
  • Product Mix Efficiency
  • First Fundamental Welfare Theorem
  • An Economy in competitive equilibrium is Pareto
    Efficient
  • Second Fundamental Welfare Theorem
  • Any Pareto-efficient resource allocation that
    society desires can be obtained through the
    market mechanism

11
When Does This Hold?
  • Under conditions of macroeconomic balance and
    perfect competition.
  • Absent those conditions due to macro-instability,
    imperfect market structure, or the existence of
    significant externalities, imperfect information,
    and/or missing markets (e.g., public goods) and
    the efficiency properties cannot be achieved.

Social Welfare Functions and the Critique of
Welfare Economics

SW
Government as corrective device to move from 1 to

Critique of this Idea
  • Inefficiencies are an Illusion
  • Marginal Costs are not appropriately calculated
  • Costs of transition from one state to another are
    not fully considered
  • No stable Social Welfare Function
  • Arrows theorem and the problems of democratic
    decision making
  • Hayek and the Limits of Agreement
  • Correctives are Worse than the Problem
  • Public Choice concerns with the manner in which
    government policy will be pursued
