My latest report - Abolish Money (From Economics)! - has been released in ebook format. (The paperback edition will be published within a few weeks.) The ebook is available at the same online booksellers as my previous books.
A big problem with conventional economics lies in integrating economics, which is concerned with the real or actual, that is, production, distribution and consumption of real goods, with finance, which is concerned with the nominal — money, cost, price, accounting, and financial assets.
The problem arises in economics as result of aggregation based on nominal value (costs, prices, etc.) without adequate consideration of the relationship of the nominal and the actual. The assumption is that this can be disaggregated by going back to journal entries to determine the prices of specific units and the number of units of various goods involved.
This is to treat money simply as a veil over barter, as conventional economists do, and to miss the role that money itself plays in the integrated economic-financial system owing to the specific dynamics of finance and the creation and use of financial assets along with real assets.
This approach is simplistic, as Keynes observed, and it leads to modeling that is not realistic enough to be very useless. In fact, the modeling can mislead, especially at junctures that are financially and economically crucial to a society.
It should be obvious that Brian is not calling for abolishing money but rather rethinking how conventional economists use the term as a key concept in economic modeling, in particular with respect to monetarisms in which interest rates are assumed to be determinative and monetary policy by the central bank rules. This is a failed approach.
