You are going to use statistical method in economic analysis is what I got.

Economics is a social science with huge complexity.

There is some analogy, Physics uses statistics plus physical laws in statistical

mechanics...what each little atom is doing in a gas is of secondary importance.

But the overall pressure, volume, temperature is of more interest. (thermodynamics)

Maybe your problem is similar. The preferences of a particular person is secondary. But there are some rules (SHY away from risky investment?).

So you use these rules to predict macroeconomic variables from what 5000000

do on a daily basis. But its very hard, psychology is in the middle. (as stampedes to the dolar for example, or when banks fail) It is not so good an analogy.

Statistical mechanics is a very similar term to statistical physics, maybe the second is more general a term.

Statistical mechanics is actually a study in which thermodynamics state of a system such as Pressure (P), Volume (V), Temperature (T) are determined by using Physical laws. P, V, T parameters are estimated by using various statistical methods. Actually in mechanics we determine the response or change in the physical system due to any external change.

Statistical Physics is a very general term which comprises mechanics actually both mean same.

So can I say the statistical mechanics use to reproduce the thermodynamics laws in a probabilistic way by using the euqations, terms, methods of statistical physics? Hisay Lama Juan Weisz

I need to clarify these two terms because i think an economy as a complex system doesn't come to exist as a result of interactions between individuals. An indivial borns in an economy which has its own rules, stuructures, constructions that also form behaviours of individuals. But also in a micro level, interactions of individuals creates some structures or structural transformations. So I'm planning to establish a mutual connections between these micro and macro spheres by using the method of statistical machanics. Could you make any suggestions for me as a references, books or something? Or should i give up this topic?

Mehmet

yes

The difference is that all atoms are identical in a uniform gas, and you know the micro laws well.

In contrast, individuals are all different and you cannot say exactly how they behave.

Sociologists know something about this, you can read in this area.

So Physics is much easier.

I think in economics you would have to play around more with some of the macro rules.

ie.

If you increase interest rates or taxes you affect the level of economic activity

negatively.

@Mehmet "So can I say the statistical mechanics use to reproduce the thermodynamics laws in a probabilistic way by using the euqations, terms, methods of statistical physics?" Yes exactly you pointed a right answer. Sorry I know reference books which highlights Physics problem not the economics, but I am sure there might be several references available in the context of econophysics.

Thank you so much Dear Juan Weisz and Hisay Lama

Statistical mechanics works for mechanical states of particles and its analogy with stock market risk/prices states. Dynamics in econophysics may be recognized with random walks economical models along Markov Chains, and also, if we go further towards thermodynamics, applying energy/entropy potentials, two physical branches may be related and we will obtain statistical physics applications.

Mantegna/Stanley: Introduction to Econophysics (Cambridge Univ Press, DOI: 10.1017/CBO9780511755767 ) is a reference, in which methods common in statistical physics are applied to economic questions. This is very insightful, as it takes the perspective of physicists.

Another refence of interest may be: Slania: Essentials of Econophysics Modelling (Oxford Univ Press)

Dear @Antonio Alatorre and @Thomas Neusius, thank you very much for your responses and advices.
