Actually many of these assumptions have been in classical economic theory since Adam Smith, if not before. Most of them can be found in Alfred Marshall. The best traditional treatment is Joan Robinson's theory of imperfect competition, and there is a recent trend for Nobel's to go to people writing about market asymmetry and information imperfections, including people like Lucas.
I wouldn't really call these assumptions. Adam Smith takes an approach on how to raise the estates of the less among us and how to elevate the suffering of those worse off. What he does is that he doesn't ask what do we have natural rights to. He just wants to know what will work to help these people. His investigation involves centuries of data, which he was able to assemble in one of his books, The Wealth of Nations. Empirically, it shows that the the best way to help those worse off among us is to allow for commerce, Free Trade, Free Migration and Limited Market Intervention.
He was never really worried about the wealth or kings. These individuals can take care of themselves.
I don't know of anyone who opposed free markets, not even Oscar Lange (University of Chicago and Polish Central Planning Board). The economic debate (as opposed to the ideological political debate which is all about money) has always been about how to make markets work more efficiently. The world is as we find it, with externalities and imperfect competition, regulatory capture and imperfect information. The greatest legacy of Milton Friedman (and the reason he is disappearing from the ideological Right, becoming an Unperson) is his exposition of the role of government using a pragmatic standard of what markets can do and what government can do to improve market behavior. It's really Friedman vs Hayek; with von Mises closer to Friedman.
There are those who want markets to be as free as possible, and then there are those who want markets to be as free as they would possibly allow. That is generally the difference between Free Market advocates and Central Planners. One school of thought believes people act in their own self interest. The other school of thought tries to influence economic and social behaviour. I find the best way to influence this behaviour is to incentivise bad people to do good things. Not because you tell them to do so, but because it's mutually beneficial for them to do so. The Free Market already has two ways of dealing with this:
- Making force or fraud unprofitable.
- The Rule Of Law.
The perfect competition model supposes a sufficient number of firms with sufficiently small market share that each views its demand curve as horizontal. The market fixes the price and the firm then determines its output. Supply curves are the aggregate of firm quantity decisions adjusted by firms entering and leaving the market. This model does not allow for branding, ignores location, and like Adam Smith's famous comment, takes a dim view of collusion. Imperfect competition spans a range from minor differentiation a la Joan Robinson (the drugstore on the corner) through progressively more market concentration to oligopoly and duopoly models and ending in outright monopoly. It's the DEGREE of monopoly power that matters, the close to the perfectly competitive model (a flea market) the more the results look like the results of the perfectly competitive model. And the reverse for markets with higher degrees of monopoly or monopsony power. To the degree that any firm can create differentiation and grow, it acquires some monopoly power (from the differentiation if not the size!) and departs from the results of the competitive model.
Now "free markets" do not mean the perfectly competitive model. But I propose that to the degree that "free markets" (I really think the term is way too elastic to have much meaning) depart from the perfectly competitive model, especially in the area of product differentiation, the less the advantages of classical economics perfect competition model will apply.
As long as there is open competition, then that is really all the competition you need. It sounds like you are advocating for a level playing field. This is really not what we want. A Free Market means that firms will work viciously for your business by producing goods and services. Some firms are better at this than others. This is mutually beneficial. but the degree of a monopoly in a free market is practically nonexistent. As long as open competitive occurs, the only way someone can obtain 100 % of the market share is if they are the absolute best at providing that good or service at the best price in which no competitor can possibly complete.
Why should this be seen as a bad thing?
What market intervention provoked the collusion Adam Smith observed in 1776? Intervention has been the response to collusion, not the other way around.
How about the East India Company? Originally charted as an organisation of merchants which have colluded and formed the East India Company and accomplished a complete trade monopoly. Adam Smith was a critic of the 18th century corporations that circumvented the operation of the market by obtaining monopoly power from the State. In the Wealth of Nations, Smith argued that the practices of monopoly corporations prevented the Age of Discovery from resulting in a generalised spread of commercial benefits. While it may be true that these were profit making enterprises, they were not true commercial capitalist businesses in the real sense of the term. The profits that they've gains were not due to free competition or voluntary corporation by willing buyers and sellers, but the use of political power. Historically, most (if not all) collusion has operated in his fashion. You have a politically privileged group of people, backed by the military power of the state, establishing trade relations with people that were not voluntary and highly exploitative.
Intervention is usually the cause of collusion, not the response. Collusion without the backing of the military power of the state is highly unstable, and the market can deal with this easily and such arrangement is almost assured to be temporary in a free market. The first and most obvious complication is determining unanimously among the participating members is determining where exactly the prices of their goods and services should be set and which member of each firm should be permitted to produce. The ones which would most naturally be uneasy about such an arrangement would be the more efficient firms. These firms are more likely to disapprove any change in their own production in favour of the less efficient ones. Also, there will always be such a temptation to cheat by lowering their agreed upon prices, or increasing their production in attempt to secure their larger share of the market. The incoordination of these actions are more likely to cause the collusion of member firms to disintegrate.
Really? Then we can throw out most of the work of the 80's and 90's. The field was dominated by work on information asymmetry and decision making in conditions of imperfect knowledge.
In a market economy, prices are the information. Prices are very important has they reveal on the value of alternative uses of each parcel of property and resource in the economy.
I'm not sure what that means. There is a difference between spot markets and futures markets. Are you referring to futures markets as a time arbitrage?
I'm talking about profits, in general.
At last we agree! "Free markets" don't handle externalities. But they could. Re-read my argument for market based solutions to pollution above.
Well, the market itself does not have a mechanism for preventing externalities. Ordinary individuals can already deal with these variables themselves in a Free Market through the role of Property Rights, which is generally the only legitimate government function.
The solutions the pollution can always be determined by asking a simple question: Who owned the property which was soiled by the pollution? Property Rights are not just to protect the wealthy, but essentially everyone. Especially the least off among us. If I dump on my own property, that hurts my bottom line. If I dump on your property, then I'll face a lawsuit.
Voucher plans for education are another example of public policy to achieve social and economic goals by encouraging market-like behavior by participants.
Yes, but this is a general solution created by the government to fix a problem the government created themselves. It's always seen as in fair that private education cost so much and these greedy educational institutions are nickle and diming these families. The voucher problem is a response to prevent the possibly of education being a luxury for the wealthy. The problem is, this has already happened. In most schools in America, you go where your zone school is. If you don't have $250,000 - $400,000 to pick up and move to another location, you're stuck in the same sub-standard learning environment.
It's not a bad solution, but you could have done better by allowing individuals to have these choices they should have without a voucher anyway...
My answer is that economic policy is a process of trial and error. Hopefully theory and history steer us away from programs that are doomed to fail by inherent flaws. After that, we go with what works and stop doing what doesn't work. Both markets and market intervention will fail some of the time. We should not give up on either. The solution to bad policy is not no policy, it is good policy.
It's much easier to have trial & error when you have different states as oppose to an entire state. The best thing these country have to learn from are other countries. Many of these countries never pull away from their economic slumps. Part of market intervention is determining where you want that role in the market to be. I'm for limited, reasonable restrictions on economic sections.
I started my economic career studying the Soviet economy. I doubt you will ever encounter a more severe critic of the central planning model than me. But the extreme "free market" model is equally unworkable. We need to work with some reasonable toolkit rather than be deluded that some form of orthodoxy (anarchistic capitalism or Marxist socialism) is a real solution. I will come down on the side of making the economic system work for the benefit of the participants in general. I believe in Adam Smith's "Invisible Hand", but I also believe as Adam Smith did, that it needs a little help from proper government policy.
Best always,

Some people want a pure free market. That's probably never going to be accomplished. Some people which government was better, not gone. No government is not required for a Free Market to work, just limited.
