This paper documents a marked increase in international consumption risk sharing throughout the recent globalization period. Unlike earlier studies that have found it difficult to document a consistent effect of financial globalization on international consumption comovements, we make use of the information implicit in the relative levels of consumption and output to measure long-run risk sharing among OECD countries and US federal states.We derive our empirical setup from a deliberately simplistic model in which countries can trade perpetual claims to each other's output (Shiller securities). Our framework allows us to distinguish between two channels of risk sharing: ex ante diversification that leads to income smoothing through capital income flows and ex-post consumption smoothing through savings and dissavings. The model successfully replicates the patterns of income and consumption smoothing observed in both U.S. state-level and international data. The increase in international consumption risk sharing is closely associated with the decline in international portfolio home bias. While capital income flows remain relatively limited as a channel of risk sharing at business cycle frequencies, we find that better international portfolio diversification has led to a considerable increase in capital income flows at medium and long horizons.

Recent changes in technology, along with the opening up of many regions previously closed to investment, have led to explosive growth in the international movement of capital. Flows from foreign direct investment and debt and equity financing can bring countries substantial gains by augmenting local savings and by improving technology and incentives. Investing companies acquire market access, lower cost inputs, and opportunities for profitable introductions of production methods in the countries where they invest. But, as was underscored recently by the economic and financial crises in several Asian countries, capital flows can also bring risks. Although there is no simple explanation of the currency crisis in Asia, it is clear that fixed exchange rates and chronic deficits increased the likelihood of a breakdown. Similarly, during the 1970s, the United States and other industrial countries loaned OPEC surpluses to borrowers in Latin America. But when the U.S. Federal Reserve raised interest rates to control soaring inflation, the result was a widespread debt moratorium in Latin America as many countries throughout the region struggled to pay the high interest on their foreign loans. International Capital Flows contains recent work by eminent scholars and practitioners on the experience of capital flows to Latin America, Asia, and eastern Europe. These papers discuss the role of banks, equity markets, and foreign direct investment in international capital flows, and the risks that investors and others face with these transactions. By focusing on capital flows' productivity and determinants, and the policy issues they raise, this collection is a valuable resource for economists, policymakers, and financial market participants.

Home bias - the empirical phenomenon that investors assign anomalously high weights to their own domestic assets - has puzzled academics for decades: financial theory predicts that an internationally well diversified portfolio of stocks and short-term bonds can reduce risk significantly without affecting expected return. Although the globalization of international equity markets has increased international investments, equity portfolios remain severely home biased today, and no single explanation seems to solve the puzzle completely. In this paper, we first provide a thorough description of the equity home bias phenomenon by defining, discussing, and applying the competing measures and presenting some estimates of the costs of under-diversification. Second, we evaluate the explanations for the equity home bias proposed in the literature such as information asymmetries, behavioral aspects, barriers to foreign investment, and governance issues, and conclude that each explanation on its own falls short, suggesting that the equity home bias probably reflects a combination of factors. Lastly, we review the implications of international under-diversification for portfolio formation and the cost of capital of companies.

A comprehensive examination of policy measures intended to help emerging markets contend with large and volatile capital flows. While always episodic in nature, capital flows to emerging market economies have been especially volatile since the global financial crisis. After peaking at $680 billion in 2007, flows to emerging markets turned negative at the onset of crisis in 2008, then rebounded only to recede again during the U.S. sovereign debt downgrade in 2011. Since then, flows have continued to swing wildly, leaving emerging market policy makers wondering whether they can put in place policies during the inflow phase that will soften the blow when flows subsequently recede. This book offers the first comprehensive treatment of policy measures intended to help emerging markets contend with large and volatile capital flows. The authors, all IMF experts, explain that, in the spirit of liberalization and deregulation in the 1980s and 1990s, many emerging market governments eliminated capital inflow controls along with outflow controls. By 2012, however, capital inflow controls were again acknowledged as legitimate policy tools. Focusing on the macroeconomic and financial-stability risks associated with capital flows, the authors combine theoretical and empirical analysis to consider the interaction between monetary, exchange rate, macroprudential, and capital control policies to mitigate these risks. They examine the effectiveness of various policy tools, discuss the practical considerations and multilateral implications of their use, and provide concrete policy advice for dealing with capital inflows.

Macrofinancial linkages have long been at the core of the IMF's mandate to oversee the stability of the global financial system. With the advent of the economic crisis, the Fund has drawn on this research in order to contribute to critical debates on the nature of appropriate policy responses at both the national and multilateral levels. The current juncture offers a good opportunity to take stock of this body of research by IMF staff and to share it with a wider audience, particularly since few collections have been published in this area. This volume brings together some of the best writing by IMF economists on macrofinancial issues, and highlights the issues and approaches that have guided IMF thinking in an area that makes up an increasingly important component of the IMF's overall remit. The chapters in the volume fit into three broad themes: financial crises and boom-bust cycles; financial integration, financial liberalization, and economic performance; and policy issues relating to macroeconomic policy and the corporate and financial sectors-including domestic and external financial liberalization.
