I found that, though most of the time the math technical parts of economics is not a problem for me, I am somehow troubled with extracting the descriptive meaning of formally stated economic statements. I seem to not have the intuition developed enough to read the economic meaning out of formal conditions. This is manifested in macroeconomics. For example, in the class of OLG models, the budget constraints may take many different forms according as scenario (with money, social security,...). Many times, after I saw how simple the economic meaning a sentence conveys either by lecturer in a class or author in a book, I asked myself how I did not see this. On the other hand, microeconomics is much more clearer to me.
So my question is how to develop a proper intuition to extract the descriptive meaning of any given economic formal relation.
