The recent global financial crisis exposed the serious limitations of existing economic and financial models. Not only did macro models fail to predict the crisis, they seemed incapable of explaining what was happening to the economy. Policymakers felt abandoned by the conventional tools of the now obsolete Washington consensus and the World Trade Organization’s oversimplified faith in free markets.The traditional models for agricultural commodities have so far failed to take into account the uncertain character of the global agricultural economy and its ferocious consequences in food price volatility, the worst in 300 years, yielding hunger riots throughout the world. This book explores the elements which could help to close this fundamental modeling gap. To what extent should traditional models be questioned regarding agricultural commodities? Are prices on these markets foreseeable? Can their evolution be either predicted or convincingly simulated, and if so, by which methods and models? Presenting contributions from acknowledged experts from several countries and backgrounds – professors at major international universities or researchers within specialized international organizations – the book concentrates on four issues: the role of expectations and capacity of prediction; policy issues related to development strategies and food security; the role of hoarding and speculation and finally, global modeling methods. The book offers a renewed wisdom on some of the core issues in the world economy today and puts forward important innovations in analyzing these core issues, among which the modular modeling design, the Momagri model being a seminal example of it. Reading this book should inspire fruitful revisions in policy-making to improve the welfare of populations worldwide.

In The Futures, Emily Lambert, senior writer at Forbes magazine, tells us the rich and dramatic history of the Chicago Mercantile Exchange and Chicago Board of Trade, which together comprised the original, most bustling futures market in the world. She details the emergence of the futures business as a kind of meeting place for gamblers and farmers and its subsequent transformation into a sophisticated electronic market where contracts are traded at lightning-fast speeds. Lambert also details the disastrous effects of Wall Street's adoption of the futures contract without the rules and close-knit social bonds that had made trading it in Chicago work so well. Ultimately Lambert argues that the futures markets are the real "free" markets and that speculators, far from being mere parasites, can serve a vital economic and social function given the right architecture. The traditional futures market, she explains, because of its written and cultural limits, can serve as a useful example for how markets ought to work and become a tonic for our current financial ills.
