What is an economic system?• “The system of production and consumption”

• Dictionary.com

• “The analysis of the causes and consequences of the significant institutional variety prevailing among all developed, developing, emerging, and transition economies, as well as attempts at and proposals for their reform.”• Economics Systems (journal)

Stylized “facts” of capitalism• Pro-growth

• Efficient

• Unstable

• Unequal final outcome

The promise of socialism• What is socialism?

• State ownership of the means of production• Is that all?

• Fabian socialism• Creeping towards state control

• Anarcho-communism• Abolition of both state and private productive property rights

The promise of socialism• What is socialism?

• A Marxian definition• Capitalism

• Exploitation of workers• Alienation of workers• Coercion of workers

The promise of socialism• What is socialism?

• A Marxian definition• Capitalism• Socialism

• The state as the new agent of exploitation• Workers remain alienated• The state as the coercive agent

The promise of socialism• What is socialism?

• A Marxian definition• Capitalism• Socialism• Communism

• The erosion of the state• The end of alienation• No coercive agent required

The promise of socialism• What is socialism?

• A Marxian definition

• What would socialism offer?• A more stable outcome• A more equal outcome

Putting socialism into practice• Two options

• No private property and a planning structure• No private property and a market

The planned version of socialism• Enrico Barone

• The possibility of mathematically solving a general equilibrium

The planned version of socialism• Enrico Barone

• Required information• Resource availability• Production functions• Demand characteristics

The planned version of socialism• Enrico Barone

• Required information

• Advantages• No market adjustment time needed• Eliminates sub-optimal market outcomes

The planned version of socialism• Enrico Barone

• Required information

• Advantages

• Core challenges• The problem of computation• Obtaining the required information• Motivating producers

Computation• Difficulty rises exponentially with size

• Non-linear functions may not have a solution

• This is a resource using process• Market is free• Outcome cannot mimic market outcome

Information and motivation• Demand characteristics

• How do markets obtain this information?• Revealed preference

Information and motivation• Demand characteristics

• Production functions• Is engineering information enough?• The role of a profit motive

Information and motivation• Demand characteristics

• Production functions

• Satisfaction behavior• Manager motivation under a plan

• Risk minimization or profit maximization

Information and motivation• Demand characteristics

• Production functions

• Satisfaction behavior• Manager motivation under a plan• The logic of stock options in a market economy

Planned socialism: the work around• Dichotomous replacement to the market

• Material balance approach• Price mechanism (and queuing) to determine final consumer sector

allocation

Planned socialism: the work around• Dichotomous replacement to the market

• Material balances example• Resources

• L = 25

• Production coefficients• aM = 0.1

• aC = 0.5

• Material balance• 0.1QM + 0.5QC = 25

Planned socialism: the work around• Dichotomous replacement to the market

• Material balances example• Resources• Production coefficients• Material balance• Targeted sector output

• Q1 = 100

• Final production solution (slack sector)• 0.1 x 100 + 0.5 x QC = 25

• QC = 2 x (25 – 10) = 30

Planned socialism: the work around• Dichotomous replacement to the market

• Material balances example• Resources• Production coefficients• Material balance• Targeted sector output• Final production solution (slack sector)• Labor allocation

• LM = 0.1 x 100 = 10

• LC = 0.5 x 30 = 15

Planned socialism: the work around• Dichotomous replacement to the market

• Material balances example

• Prices?• Targeted sector not needed• Inputs not needed

• Non-market allocation

• Residual sector?

Planned socialism: the work around• Advantages

• Reduced information set required• Easier linear system of equations to solve

Planned socialism: the work around• Advantages

• Remaining concerns• How are production coefficients determined?

• Is engineering data sufficient?

Planned socialism: the work around• Advantages

• Remaining concerns• How are production coefficients determined?• How do ensure compliance with production coefficients?

Incentives and planning• Are moral incentives enough?

• Is this socialism or communism?

Incentives and planning• Are moral incentives enough?

• Implementing material incentives• Judgment criteria

• Quantity goals• Quality goals

Incentives and planning• Are moral incentives enough?

• Implementing material incentives• Judgment criteria• Monitoring bureaucracy • Reward structure

• Monetary rewards and the problem of inflation• Will this work?

Incentives and planning• Are moral incentives enough?

• Implementing material incentives• Judgment criteria• Monitoring bureaucracy • Reward structure

• Monetary rewards and the problem of inflation• Non-monetary rewards and shortages

A missing signal and planning• János Kornai

• Capitalism• The cost minimization/profit maximization dual• Impact of a declining resource on production decisions?

A missing signal and planning• János Kornai

• Capitalism• Planning mechanism

• Input mix• Historical accident• Difficulty of altering the input coefficient

A missing signal and planning• János Kornai

• Capitalism• Planning mechanism

• Input mix• No input price signal• Production rigidity and “inevitable” shortages

Assessing socialism• Data limits

• The environmental problem• Time period: 1965-1988

• Countries for comparison• Capitalist

• US• W. Germany• Japan• UK• Canada

The market version of socialism• Ward-Vanek version

• Worker self management

The market version of socialism• Ward-Vanek version

• A change to property rights• Each employee has equal ownership share• No right of disposal

The market version of socialism• Ward-Vanek version

• A change to property rights

• Stylized characteristics• Worker management board replaces board of directors• Prices/wages set by market

• Inequality remains (but mitigated)

• Firms maximize and keep profits• Each worker earns equal profit share

• No employment coercion• No stock market

The market version of socialism• Ward-Vanek version

• A change to property rights

• Stylized characteristics

• Does it work?• Employment-equality trade-off• Will it spur greater worker effort?

• Logic of stock options
