Economic Merry-Go-Round (RLE: Business Cycles) [PDF ebook] 
A New Theory of Trade Cycles with the Document of History as Proof

Originally published in the Great Depression this accessible volume was aimed not only at the academic economist, but also the general reader.

The commodities of wheat and gold are discussed in detail, and comparisons made between UK and US budget surpluses and deficits.
