Original Research ArticleJournal of Economics and Business, Volume 56, Issue 4, July–August 2004, Pages 273-285Ruth A Judson, Richard D PorterAbstract:We evaluate US regional currencydemands using a panel dataset covering the 37 Federal Reserve Cash Offices over 25 years from 1974 to 1998. We find strong support for the transaction specification, in which currency depends on a transaction measure and nominal interestrate for all denominations, large denominations, and US $20. This result is generally robust to the inclusion of wide variety of additional economic and demographic variables. Beyond the traditional transaction terms, seven other variables stand out in the specifications we entertain: the age distribution of the population, bankruptcies, crime, employment, housing permits and starts, and transfer payments. Finally, we show that international currencydemand was generally an important influence during the period; when its influence is disregarded, the findings are muddied considerably.The following tests were made:– Combined wet–dry cycles using fresh water, seawater and water containing 5% sulphates– Accelerated ageing in an autoclave– Accelerated carbonationThe performance of the concrete containing sludge was acceptable and comparable to the results obtained for the reference concrete not containing sludge.Keywords: Currency; Domestic; International; Money demand; Panel2. Black market exchange rate, currency substitution and the demand for money in LDCs Original Research ArticleEconomic Systems, Volume 30, Issue 3, October 2006, Pages 249-263 Mohsen Bahmani-Oskooee, Altin TankuAbstract:Mundell's conjecture in 1963 that the demand for money could depend on the exchange rate in addition to income and interestrate has received some attention in the literature by including the official exchange rate and estimating the money demand in a few developed countries. In less developed countries, since there is a black market for foreign exchange, it has been suggested that the black market exchange rate rather than the official rate should be the determinant of the demand for money in LDCs. This proposition is tested by estimating the demand for money for 25 LDCs using the bounds testing approach to cointegration. The main conclusion is that while in some LDCs, the black market rate enters into the formulation of the demand for money, in some others the official rate is the determinant. The black market premium also played a role in some countries.JEL classification• E41;• F31Keywords: Money demand; Black market exchange rate; Bounds testing3. An oil demand and supply model incorporating monetary policy Original Research ArticleEnergy, Volume 35, Issue 5, May 2010, Pages 2013-2021Hossein Askari, Noureddine KricheneAbstract:Oil price inflation may have had a significant role in pushing the world economy into its worst post-war recession during 2008–2009. Reserve currency central banks pursued an overly expansionary monetary policy during 2001–2009, in the form of low or negative real interestrates and accompanied by a rapidly falling US dollar, while paying inadequate attention to the destabilizing effects on oil markets. In this paper, we show that monetary policy variables, namely key interestrates and the US dollar exchange rate, had a powerful effect on oil markets. World oil demand was significantly influenced by interest and dollar exchangerates, while oil supply was rigid. Oil demand and supply have very low price elasticity and this characteristic makes oil prices highly volatile and subject to wider fluctuations than the prices of other commodities. Aggressive monetary policy would stimulate oil demand, however, it would be met with rigid oil supply and would turn inflationary and disruptive to economic growth if there was little excess capacity in oil output. We argue that a measure of stability in oil markets cannot be achieved unless monetary policy is restrained and real interestrates become significantly positive. Monetary tightening during 1979–1982 might implythat monetary policy has to be restrained for a long period and with high interestrates in order to bring stability back to oil markets.

Introduction(首段)The world economy experienced its worst post-WWII recession during 2008–2009 as oil prices raced from $20/barrel in 2001 to over $147/barrel in July 2008.1 Left unchecked and largely ignored by reserve currency central bankers, high fuel prices diverted large quantities of grains to the production of ethanol, putting pressure on corn and soybean markets; disrupted agriculture, airlines, auto industry; set off food riots in vulnerable countries; led to oil protests in major industrial countries; and aggravated poverty and unemployment around the world.(末段)During 2001–2008, major reserve currency central banks followed a highly expansionary monetary policy that ignited rapid commodity price inflation. Food and oil prices rose at unprecedented pace and reached levels that triggered riots and protests. Such a policy disrupted vital food and energy markets, and was a factoring the ensuing economic recession and high unemployment. In response to the recession during 2008–2009, reserve central banks decided to keep key money market rates near zero bounds and to expand the supply of money. This policy could encourage more speculation in commodity markets, especially in markets that face rigid demand and supply, such as oil. The data for 1976–1986 shows that monetary policy may have to be tightened significantly in order to reduce commodity price inflation and that money market interest rates, such as the LIBOR or the federal funds rate, may have to be maintained on average at levels similar to those during 1986–2001 in order to restore long-term stability in oil markets. Based on monetary tightening during 1979–1982, the period of monetary restraint may have to be extended over many years and interest rates may have to rise significantly before long-term oil market stability can be restored.七、参考文献 References1.[1]J.D.
