15/1/2018 Why neoliberalism is harmful (2)

Neoclassical economics has firms and households but does not consider their efficiency. Its object of analysis is market efficiency only. What a narrow worldview it is! Relying on neoliberalism, therefore, implies regarding the world as made up of only markets.
Our society is made up not only of markets but also of households, firms (organizations), schools, hospitals, governments, communities, social & natural environments, and so forth. Neoclassical economics, however, has a systematic theory only about markets. It can teach in its own way how one should behave in markets but it cannot do so for households, firms (organizations), schools, hospitals, governments, communities, or environments since it has no theories about these.
Therefore, neoclassical economics considers only partial efficiency, i.e. the efficiency of the markets only. We need to consider, however, total efficiency, i.e. the efficiency of whole society including households, firms (organizations), schools, hospitals, governments, communities, social & natural environments, and so on, because our welfare depends on all of these.
One might think that the efficiency of different parts of society is analyzed in different academic fields, but we need to consider all parts simultaneously, since a factor that makes one part efficient might make another inefficient. When maximizing the sum of two functions, one should not maximize each function separately. Separate maximizations would generally lead to contradictory solutions.
Since neoclassical economics considers market efficiency only, policies based on neoliberalism tend to generate inefficient households, firms (organizations), communities, or environments. Such policies are often pathological. For example, high flexibility of labor markets is likely to destroy organization efficiency because of insufficiency of intra-firm training, cooperation among employees, or knowledge of stakeholders.
No less important is the fact that even the markets in the real economy are unlikely to be efficient. The market efficiency in neoclassical economics is proved under the assumption of contract completeness. In other words, neoclassical economics assumes that all transactions are carried out with sufficiently detailed contracts that ferment no disputes between sellers and buyers. In many transactions in the real economy, such contracts are impossible because of astronomically high transaction costs.

The Nature of Economics (3)

The Nature of Economics (3) A crucial defect of neoclassical economics related to the above discussion is that it analyzes seriously only markets, more specifically organized markets. It does not seriously analyze firms or households. It ignores government, the environment, and international relations. Although the real economy has a variety of market types, it treats all markets as the same type. Can the demand-supply analysis (with auctioneers) be applied to medical markets or education markets? This implies that neoclassical economics analyzes only a limited part of the economy. Although it deals with firms, it does not seriously analyze them in the sense that it fails to explain how a particular set of input levels achieves the level of output given by the production function. In other words, it does not describe the process of production or how production is carried out. Firms in the real economy try hard to improve their technologies. They also try to invent new products

The Nature of Economics (7) Neoclassical economics does not consider efficiency of the whole economy because the production function and utility function are exogenously given. Since I do not think that this point is made clear in books or papers, I would like to discuss it in some detail. Consider two economies E1 and E2. The workers in E1 are more cooperative and hard-working. Those in E2 are selfish and lazy. Hence, the labor productivity in the firm in E1 is higher for equally given levels of physical inputs. However both economies are efficient in neoclassical economics! Both E1 and E2 are efficient as far as all firms maximize their profits subject to exogenously given (different) production functions! It is obvious that E1 is more affluent than E2. I would like to emphasize that efficiency differs from affluence in neoclassical economics. Next consider two economies E3 and E4. The people in E3 are more harmonious and other-regarding within the household. Those in E4 ar

The Nature of Economics (5) We see here a good example for the fact that the values researchers possess affect their choice of the topic and method of research generating bias in ‘scientific works.’ 　 Researchers who want to support individualism do not analyze firms or households seriously. They simply introduce exogenously given production functions and utility functions. Economists tend to ignore or distort social aspects that are inconvenient to build models with conclusions they like. It is really hard to establish social sciences that are value-free. Researchers need to recognize this. On the other hand, a unified theoretical model may be formed to explain the cultural difference mentioned in the example given in the above third reason. It may be done by introducing a measure of the degree of cooperativeness as an exogenous variable. In such a model different types of equilibrium may arise for different values of the measure. If we can endogenize the variable for that m
