Perfect competition uutopia
When I started studying economics and learned about perfect competition and its assumptions I thought it was totally unrealistic. I really enjoyed the joke about the economist who wanted to assume he had a can opener.
However, through the years I have come to see perfect competition as an utopia which provides guidelines for policy. I like the perfect competition model because it provides high efficiency, equality in that there are no profits, it works without economic growth and decision making is by individual consumers rather than governments.
One of the features of perfect competition is that there are no profits because if profits are being made in an industry others will enter that industry increasing competition and driving prices down until there are no more profits.
To get around this no profit feature business people lobby governments to pass legislation which restricts competition. For example, subsidies, some taxes, licensing, copyright and patent legislation all interfere with perfect competition.
To make our economy more competitive we should:
– Give subsidies to consumers rather than producers. This way prices will reflect true costs and buyers can make decisions according to their own values.
– Require producers to provide consumers will all relevant information about their products.
– Abolish patent and copyright legislation.
– Unilaterally abolish import and export tariffs.
Following is a summary of the assumptions for perfect competition.

Assumptions behind a Perfectly Competitive Market
1. Many suppliers each with an insignificant share of the market â€“ this means that each firm is too small relative to the overall market to affect price via a change in its own supply â€“ each individual firm is assumed to be a price taker
2. An identical output produced by each firm â€“ in other words, the market supplies homogeneous or standardized products that are perfect substitutes for each other. Consumers perceive the products to be identical
3. Consumers have perfect information about the prices all sellers in the market charge â€“ so if some firms decide to charge a price higher than the ruling market price, there will be a large substitution effect away from this firm
4. All firms (industry participants and new entrants) are assumed to have equal access to resources (technology, other factor inputs) and improvements in production technologies achieved by one firm can spill-over to all the other suppliers in the market
5. There are assumed to be no barriers to entry & exit of firms in long run â€“ which means that the market is open to competition from new suppliers â€“ this affects the long run profits made by each firm in the industry. The long run equilibrium for a perfectly competitive market occurs when the marginal firm makes normal profit only in the long term
6. No externalities in production and consumption so that there is no divergence between private and social costs and benefits.
