Microeconomics, Macroeconomics and Consciousness.

Economic theorizing (except for some heterodox schools), follows the empirical method of investigation, primarily subjected to the principles of logical consistency and empirical falsification. In such a methodological set up, it’s imperative to understand the definitional categories of Economics so as to understand the subject and the ongoing research properly.

The definitions of Macroeconomics and Microeconomics are one such area. Historical developments and the contribution of numerous Economists have helped develop a particular definition of these terms. It is possible to understand them in one more way- as the results of conscious and unconscious individual decision making.

In Microeconomic analysis, an economy is essentially disaggregated into individual units, at the most being grouped into a non-aggregate group- such as industry, market, etc. The individuals are assumed to follow certain behavioural assumptions such as rationality, transitivity, etc. and are expected to do so under certain environmental settings such as under a particular market structure, under particular macroeconomic environment.

Methodological individualism thus considers an individual consumer or a producer as the fundamental unit of analysis. The results of this rationalized individual’s decision making through her interaction with other similar individuals produces Microeconomic outcomes. These outcomes are mainly in terms of Price, Demand and Supply generated in a market (whether labour, product or factor). What is to be noted here is that these economic outcomes are the result of conscious decision making by these individuals. The individuals consciously act and react in a particular manner which gives rise to their anticipated results. For e.g. when buyers and sellers negotiate over price, the outcome is something that is a result of their conscious efforts to reach that result- otherwise they wouldn’t get into it in the first place.

Contrast this with aggregated outcomes- as analyzed by Macroeconomics. Numerous individuals are aggregated into broad units of analyses- such as Households, Firms, Government and Foreign sector or in terms of markets- such as labour, goods, money and assets markets. The interaction of ‘aggregated’ individuals in these markets cuts across a hugely heterogeneous set of objective functions of individuals- all undertaking conscious rationalized decision making to achieve their desired economic outcomes.

Yet, what is surprising is that the macroeconomic outcomes produced by individual decision making units through their interactions in these aggregated markets are not at all produced by any conscious efforts to achieve these outcomes. Macroeconomic outcomes are primarily in terms of Output, inflation, unemployment, interest rate, exchange rate, price level, etc. None of these macroeconomic outcomes (produced by the macroeconomy) is a part of a microeconomic unit’s objective function, yet the diverse and theoretically infinite objective functions (due to subjective, non-comparable preference rankings of individuals) somehow fulfil the macroeconomic objective function- viz. of price and output stability and other such macro-policy objectives.

Macroeconomic outcomes are thus an unconscious result of conscious individual decision making and economic activity. This difference of the type of human consciousness that is associated with macroeconomics and microeconomics may open up new doors of understanding the role that Analytical Philosophy (and especially ontology) can play in appreciating better the beauty and breadth of the discipline of economics.
