Слайд 3Questions
How do you understand efficiency?
Do you agree that technical progress is always
positive?
Should we spend money in Research and development or should be in current Production?
What is the difference between efficiency and technical progress?
Слайд 4Efficiency and Technical Progress
Economic regulations should promote efficiency and technical progress.
Efficiency
is concerned with optimizing the use of existing resources and technology.
Technical progress is conditional on the allocation of resources to develop new technologies.
Слайд 5Efficiency and Technical Progress
Efficiency is static, technical progress is dynamic.
Different types
of market structures may impact efficiency and technical progress differently
Слайд 6Assumptions of Perfect Competition
Consumers are perfectly informed about all goods.
There are
many buyers and sellers in the market
Consumers maximize preferences given budget constraints, producers maximize profits given their production functions.
All agents are price-takers
A competitive equilibrium is determined by opposing forces of demand and supply.
Слайд 7Pareto equilibrium
Pareto efficiency – equilibrium cannot be replaced by another one
that would increase the welfare of consumers without harming others.
Price = Marginal Cost
All firms price takers.There are no super-normal profits.
However in practice economic regulation is often concentrated on industries where the assumptions of perfect competition do not hold.
Слайд 8Partial equilibrium welfare tools
The compensation principle – choose policy that yield the
highest economic surplus.
The change is “good” if the “winners” from any policy change can compensate the “losers”.
Слайд 11Social weights and why they matter
Society does not usually make decisions based
on the maximisation of the sum of producer and consumer surplus.
It usually attaches different weights to different groups of consumers and producers (and the government).
Example of regulating casinos. Deregulation of casinos may effect those who cannot afford to gamble and the very rich impacting on consumer surplus. However it may also raise the producer surplus by increasing the profitability of casinos
Слайд 12How to improve social welfare in Natural Monopoly Industries
Government ownership e.g. USPS
Regulation of prices e.g. Electric Utilities
Introduction of competition e.g. Telephony
Слайд 13Other types of market structure with deadweight losses
Monopsony – where a single
buyer drives down the price it pays and the quantity it buys.
Oligopoly – the intermediate case between perfect competition and monopoly where a small number of firms operate in a market with some ability to raise prices and reduce industry output.
Oligopsony – where small groups of buyers drive down price paid and quantity bought.
Слайд 14X-Inefficiency
X-inefficiency (Leibenstein, 1956) occurs when firms do not minimise the costs of
producing their output.
It is the difference between efficient behavior of firms assumed or implied by economic theory and their observed behavior in practice.
X-inefficiency occurs due to lack of competition or incentive to minimise costs within firms.
Monopolies may be particularly prone to such inefficiency.
Слайд 15Monopoly-Induced Waste
Inefficiency is created by competition among agents to become a monopolist.
Rent-seeking
behavior
Lobbying legislators (entry regulations or import quotas)
Bribing legislators of regulators
Excessive non-price competition (advertising campaigns)
Слайд 16Technical Progress
Schumpeter famously argued that monopoly was good for innovation because
the competition for monopoly encouraged investment in innovation.
Research and Development expenditure can take a number of different forms and involves different stages:
Basic research (knowledge for own sake)
Applied research (director toward particular product)
Invention (discovery of new knowledge)
Development
Diffusion
