The Volatility Trap


Book Description

We study the effects of permanent and temporary income shocks on precautionary saving and investment in a "store-or-sow" model of growth. High volatility of permanent shocks results in high precautionary saving in the safe asset and low investment, or a "volatility trap." Namely, big savers invest relatively little. In contrast, low volatility of permanent shocks leads to low precautionary saving and high or low investment, depending on the volatility of temporary shocks. Empirical evidence shows a nonlinear relationship between investment and saving and that investment is a hump-shaped function of the volatility of permanent shocks, as predicted by the model.




Global Uncertainty and the Volatility of Agricultural Commodities Prices


Book Description

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.




The Volatility Machine


Book Description

This book presents a radically different argument for what has caused, and likely will continue to cause, the collapse of emerging market economies. Pettis combines the insights of economic history, economic theory, and finance theory into a comprehensive model for understanding sovereign liability management and the causes of financial crises. He examines recent financial crises in emerging market countries along with the history of international lending since the 1820s to argue that the process of international lending is driven primarily by external events and not by local politics and/or economic policies. He draws out the corporate finance implications of this approach to argue that most of the current analyses of the recent financial crises suffered by Latin America, Asia, and Russia have largely missed the point. He then develops a sovereign finance model, analogous to corporate finance, to understand the capital structure needs of emerging market countries. Using this model, he finally puts into perspective the recent crises, a new sovereign liability management theory, the implications of the model for sovereign debt restructurings, and the new financial architecture. Bridging the gap between finance specialists and traders, on the one hand, and economists and policy-makers on the other, The Volatility Machine is critical reading for anyone interested in where the international economy is going over the next several years.




The Dollar Trap


Book Description

Why the dollar is—and will remain—the dominant global currency The U.S. dollar's dominance seems under threat. The near collapse of the U.S. financial system in 2008–2009, political paralysis that has blocked effective policymaking, and emerging competitors such as the Chinese renminbi have heightened speculation about the dollar’s looming displacement as the main reserve currency. Yet, as The Dollar Trap powerfully argues, the financial crisis, a dysfunctional international monetary system, and U.S. policies have paradoxically strengthened the dollar’s importance. Eswar Prasad examines how the dollar came to have a central role in the world economy and demonstrates that it will remain the cornerstone of global finance for the foreseeable future. Marshaling a range of arguments and data, and drawing on the latest research, Prasad shows why it will be difficult to dislodge the dollar-centric system. With vast amounts of foreign financial capital locked up in dollar assets, including U.S. government securities, other countries now have a strong incentive to prevent a dollar crash. Prasad takes the reader through key contemporary issues in international finance—including the growing economic influence of emerging markets, the currency wars, the complexities of the China-U.S. relationship, and the role of institutions like the International Monetary Fund—and offers new ideas for fixing the flawed monetary system. Readers are also given a rare look into some of the intrigue and backdoor scheming in the corridors of international finance. The Dollar Trap offers a panoramic analysis of the fragile state of global finance and makes a compelling case that, despite all its flaws, the dollar will remain the ultimate safe-haven currency.

The Natural Resources Trap


Book Description

"This book is important and timely, bringing together some of the world's leading economists. The theory chapters provide new insights and apply new developments in contract theory to the problems of natural resources and credible host country policies. The case studies provide up-to-date illustrations of the difficulties and development of host country policy in Latin America and the UK." Roderick Duncan, Charles Sturt University, Australia "This book is likely to become a standard reference in the area of natural resources and credible host country policies-coming, as it does, with a solid grounding in modern economic theory." Tim Worrall, University of Manchester Volatility in commodity prices has been accompanied by perpetual renegotiation of contracts between private investors in natural resource production and the governments of states with mineral and energy wealth. When prices skyrocket, governments want a larger share of revenues, sometimes to the point of nationalization or expropriation; when prices fall, larger state participation becomes a burden and the private sectoris called back in. Recent and newsworthy changes in the price of oil (which fell from an all-time high of $147 in mid-2008 to $40 by year's end) are notable for their speed and the steepness of their rise and fall, but the up-and-down pattern itself is not unusual. If the unpredictability of commodity prices is so predictable, why do contracts not allow for this with mechanisms that would provide a more stable commercial framework? In The Natural Resources Trap, top scholars address this guestion in terms of both theory and practice. Theoretical contributions range across a number of fields, from contract theory to public finance, and treat topics that include taxation, royalties, and expropriation cycles. Case studies examine experiences in the U.K., Bolivia, Argentina, Venezuela, and other parts of the world. --Book Jacket.
