“Market power and externalities are examples of a general phenomenon called market failure—the inability of some unregulated markets to allocate resources efficiently. When markets fail, public policy can potentially remedy the problem and increase economic efficiency. Microeconomists devote much effort to studying when market failure is likely and what sorts of policies are best at correcting market failures. As you continue your study of economics, you will see that the tools of welfare economics developed here are readily adapted to that endeavor. Despite the possibility of market failure, the invisible hand of the marketplace is extraordinarily important.”

“Markets can be efficient or inefficient; so can governments. thus market failure is a counterpoint to government failure.”

“1. The standard neoclassical model the formal articulation of Adam Smith's invisible hand, the contention that market economies will ensure economic efficiency provides little guidance for the choice of economic systems, since once information imperfections (and the fact that markets are incomplete) are brought into the analysis, as surely they must be, there is no presumption that markets are efficient.
2. The Lange-Lerner-Taylor theorem, asserting the equivalence of market and market socialist economies, is based on a misguided view of the market, of the central problems of resource allocation, and (not surprisingly, given the first two failures) of how the market addresses those basic problems.
3. The neoclassical paradigm, through its incorrect characterization of the market economies and the central problems of resource allocation, provides a false sense of belief in the ability of market socialism to solve those resource allocation problems. To put it another way, if the neoclassical paradigm had provided a good description of the resource allocation problem and the market mechanism, then market socialism might well have been a success. The very criticisms of market socialism are themselves, to a large extent, criticisms of the neoclassical paradigm.
4. The central economic issues go beyond the traditional three questions posed at the beginning of every introductory text: What is to be produced? How is it to be produced? And for whom is it to be produced? Among the broader set of questions are: How should these resource allocation decisions be made? Who should make these decisions? How can those who are responsible for making these decisions be induced to make the right decisions? How are they to know what and how much information to acquire before making the decisions? How can the separate decisions of the millions of actors decision makers in the economy be coordinated?
5. At the core of the success of market economies are competition, markets, and decentralization. It is possible to have these, and for the government to still play a large role in the economy; indeed it may be necessary for the government to play a large role if competition is to be preserved. There has recently been extensive confusion over to what to attribute the East Asian miracle, the amazingly rapid growth in countries of this region during the past decade or two. Countries like Korea did make use of markets; they were very export oriented. And because markets played such an important role, some observers concluded that their success was convincing evidence of the power of markets alone. Yet in almost every case, government played a major role in these economies. While Wade may have put it too strongly when he entitled his book on the Taiwan success Governing the Market, there is little doubt that government intervened in the economy through the market.
6. At the core of the failure of the socialist experiment is not just the lack of property rights. Equally important were the problems arising from lack of incentives and competition, not only in the sphere of economics but also in politics. Even more important perhaps were problems of information. Hayek was right, of course, in emphasizing that the information problems facing a central planner were overwhelming. I am not sure that Hayek fully appreciated the range of information problems. If they were limited to the kinds of information problems that are at the center of the Arrow-Debreu model consumers conveying their preferences to firms, and scarcity values being communicated both to firms and consumers then market socialism would have worked. Lange would have been correct that by using prices, the socialist economy could "solve" the information problem just as well as the market could. But problems of information are broader.”

“We need to recognise that the entire information sector—from music to newspapers to telecoms to internet to semiconductors and anything in-between—has become subject to a gigantic market failure in slow motion. A market failure exists when market prices cannot reach a self-sustaining equilibrium. The market failure of the entire information sector is one of the fundamental trends of our time, with far-reaching long-term effects, and it is happening right in front of our eyes.”

Eli Noam (1946) professor of Finance and Economics at the Columbia Business School
