Frances Cairncross & Hamish McRae 
Second Great Crash [PDF ebook] 

Using highly-readable, non-technical language, the authors, both professional economists, describe all the major global economic forces at work in the 1970s and forecast the kind of future which such forces are creating (and which has indeed been the case). Inflation and recession, an energy crisis, international monetary disorder and a food crisis in the developing world are all discussed.
