The Role of Time-Varying Price Elasticities in Accounting for Volatility Changes in the Crude Oil Market
There has been a systematic increase in the volatility of the real price of crude oil since 1986, followed by a decline in the volatility of oil production since the early 1990s. We explore reasons for this evolution. We show that a likely explanation of this empirical fact is that both the short-run price elasticities of oil demand and of oil supply have declined considerably since the second half of the 1980s. -
17 November 2011 The International Monetary System: An Assessment and Avenue for Reform
The current international monetary system is in need of reform. This article first provides an assessment of the existing system, highlighting both its strengths and weaknesses. It notes that the system has not facilitated the symmetric and timely adjustment in the real exchange rate necessary to accommodate the integration of China and other emerging-market economies into the global economy. This lack of adjustment contributed to the global financial crisis and recession and, because it is forestalling the required rotation of global demand, is hindering the global recovery. The article then discusses reform of the system that would see all systemically important countries and currency areas adopt market-based and convertible floating exchange rates supported by appropriate monetary, fiscal and financial sector policy frameworks. It also examines the roles of the G-20 countries and major international financial institutions in promoting and facilitating the system’s transition. -
Determinants of Financial Stress and Recovery during the Great Recession
In this paper, we explore the link between stress in the domestic financial sector and the capital flight faced by countries in the 2008-9 global crisis. Both the timing of emergence of internal financial stress in developing economies, and the size of the peak-trough declines in the stock price indices was comparable to that in high income countries, indicating that there was no decoupling, even before Lehman Brothers’ demise.
