Wealthy, powerful, and potentially dangerous, hedge-find managers have emerged as the stars of twenty-first century capitalism. Based on unprecedented access to the industry, More Money Than God provides the first authoritative history of hedge funds. This is the inside story of their origins in the 1960s and 1970s, their explosive battles with central banks in the 1980s and 1990s, and finally their role in the financial crisis of 2007-9. Hedge funds reward risk takers, so they tend to attract larger-than-life personalities. Jim Simons began life as a code-breaker and mathematician, co-authoring a paper on theoretical geometry that led to breakthroughs in string theory. Ken Griffin started out trading convertible bonds from his Harvard dorm room. Paul Tudor Jones happily declared that a 1929-style crash would be 'total rock-and-roll' for him. Michael Steinhardt was capable of reducing underlings to sobs. 'All I want to do is kill myself,' one said. 'Can I watch?' Steinhardt responded. A saga of riches and rich egos, this is also a history of discovery. Drawing on insights from mathematics, economics and psychology to crack the mysteries of the market, hedge funds have transformed the world, spawning new markets in exotic financial instruments and rewriting the rules of capitalism. And while major banks, brokers, home lenders, insurers and money market funds failed or were bailed out during the crisis of 2007-9, the hedge-fund industry survived the test, proving that money can be successfully managed without taxpayer safety nets. Anybody pondering fixes to the financial system could usefully start here: the future of finance lies in the history of hedge funds.

This economic and political science work is a rigorous analysis that demonstrates that although it is a privilege and a benefit for the US to have its currency, the dollar, as the leading world reserve currency, the privilege also proves to be a very significant economic and security burden imposed on the nation.

A powerful new understanding of global currency trends, including the rise of the Chinese yuan At first glance, the history of the modern global economy seems to support the long-held view that the currency of the world’s leading power invariably dominates international trade and finance. But in How Global Currencies Work, three noted economists overturn this conventional wisdom. Offering a new history of global finance over the past two centuries and marshaling extensive new data to test current theories of how global currencies work, the authors show that several national monies can share international currency status—and that their importance can change rapidly. They demonstrate how changes in technology and international trade and finance have reshaped the landscape of international currencies so that several international financial standards can coexist. In fact, they show that multiple international and reserve currencies have coexisted in the past—upending the traditional view of the British pound’s dominance before 1945 and the U.S. dollar’s postwar dominance. Looking forward, the book tackles the implications of this new framework for major questions facing the future of the international monetary system, including how increased currency competition might affect global financial stability.

For more than half a century, the U.S. dollar has been not just America's currency but the world's. It is used globally by importers, exporters, investors, governments and central banks alike. Nearly three-quarters of all $100 bills circulate outside the United States. The dollar holdings of the Chinese government alone come to more than $1,000 per Chinese resident. This dependence on dollars, by banks, corporations and governments around the world, is a source of strength for the United States. It is, as a critic of U.S. policies once put it, America's "exorbitant privilege." However, recent events have raised concerns that this soon may be a privilege lost. Among these have been the effects of the financial crisis and the Great Recession: high unemployment, record federal deficits, and financial distress. In addition there is the rise of challengers like the euro and China's renminbi. Some say that the dollar may soon cease to be the world's standard currency--which would depress American living standards and weaken the country's international influence. In Exorbitant Privilege, one of our foremost economists, Barry Eichengreen, traces the rise of the dollar to international prominence over the course of the 20th century. He shows how the greenback dominated internationally in the second half of the century for the same reasons--and in the same way--that the United States dominated the global economy. But now, with the rise of China, India, Brazil and other emerging economies, America no longer towers over the global economy. It follows, Eichengreen argues, that the dollar will not be as dominant. But this does not mean that the coming changes will necessarily be sudden and dire--or that the dollar is doomed to lose its international status. Challenging the presumption that there is room for only one true global currency--either the dollar or something else--Eichengreen shows that several currencies have shared this international role over long periods. What was true in the distant past will be true, once again, in the not-too-distant future. The dollar will lose its international currency status, Eichengreen warns, only if the United States repeats the mistakes that led to the financial crisis and only if it fails to put its fiscal and financial house in order. The greenback's fate hinges, in other words, not on the actions of the Chinese government but on economic policy decisions here in the United States. Incisive, challenging and iconoclastic, Exorbitant Privilege, which was shortlisted for the FT Goldman Sachs 2011 Best Business Book of the Year, is a fascinating analysis of the changes that lie ahead. It is a challenge, equally, to those who warn that the dollar is doomed and to those who regard its continuing dominance as inevitable.

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.

"Gross stocks of foreign assets have increased rapidly relative to national outputs since 1990, and the short-run capital gains and losses on those assets can amount to significant fractions of GDP. These fluctuations in asset values render the national income and product account measure of the current account balance increasingly inadequate as a summary of the change in a country's net foreign assets. Nonetheless, unusually large current account imbalances, especially deficits, should remain high on policymakers' list of concerns, even for the richer and less credit-constrained countries. Extreme imbalances signal the need for large and perhaps abrupt real exchange rate changes in the future, changes that might have undesired political and financial consequences given the incompleteness of domestic and international asset markets. Furthermore, of the two sources of the change in net foreign assets -- the current account and the capital gain on the net foreign asset position -- the former is better understood and more amenable to policy influence. Systematic government attempts to manipulate international asset values in order to change the net foreign asset position could have a destabilizing effect on market expectations"--NBER website
