The paper explores how international integration through global value chains shapes the working of exchange rates to induce external adjustment both in the short and medium run. The analysis indicates that greater integration into international value chains reduces the exchange rate elasticity of gross trade volumes. This result holds both in the short and medium term, pointing to the rigidity of value chains. At the same time, greater value chain integration is associated with larger gross trade flows, relative to GDP, which tends to amplify the effect of exchange rate movements. Overall, combining these two results suggests that, for most countries, integration into global value chains does not materially alter the working of exchange rates and the benefits of exchange rate flexibility in facilitating external adjustment remain.

This issue of Finance & Development presents success and works of IMF in the past 75 years since its formation. The IMF’s financial firepower must be increased substantially, particularly in a world of relatively free capital flows. If the world of cooperative globalization is to survive and the IMF is to maintain its role within it, a great deal must change. Some of these changes are within the IMF’s control. The most important challenges for the IMF of tomorrow are, however, those created by the changing world. Global cooperation is needed to reap the benefits and avoid the pitfalls of cross-border capital flows. Cross-border capital flows are neither an unmitigated blessing nor an undoubted curse. Used judiciously, they can be beneficial to recipient countries, making up deficiencies in the availability of long-term risk capital and reducing gaps in local corporate governance. Many emerging market economies have understood that they should build foreign exchange reserves. The IMF model suggests that fluctuations in the exchange rate are the main reason for fluctuations in corporate liquidity in receiving countries.

We examine the properties of house price fluctuations across 18 advanced economies over the past 40 years. We ask two specific questions: First, how synchronized are housing cycles across these countries? Second, what are the main shocks driving movements in global house prices? To address these questions, we first estimate the global components in house prices and various macroeconomic and financial variables. We then evaluate the roles played by a variety of global shocks, including shocks to interest rates, monetary policy, productivity, credit, and uncertainty, in explaining house price fluctuations using a wide range of FAVAR models. We find that house prices are synchronized across countries, and the degree of synchronization has increased over time. Global interest rate shocks tend to have a significant negative effect on global house prices whereas global monetary policy shocks per se do not appear to have a sizeable impact. Interestingly, uncertainty shocks seem to be important in explaining fluctuations in global house prices.

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.
