The price of oil has risen by about 60% since mid-2004 and by more than 40% since the beginning of 2005. Though the U.S. economy has apparently absorbed this supply shock well so far, the path of future oil prices remains a concern for monetary policymakers. Higher oil prices can damp demand, as...

We argue that Islamic principles, in particular the avoidance of ribā and gharar should be applied with respect to real economic value rather than to monetary value in terms of conventional currency. In order to reconcile monetary value with economic value, we propose a reference currency...

This paper evaluates how different types of speculation affect the volatility of commodities' futures prices. We adopt four indexes of speculation: Working's T, the market share of non-commercial traders, the percentage of net long speculators over total open interest in future markets, which...

We assess the causes and implications of the greater financial participation in commodity markets post-2003. Focusing on crude oil, we build a calibrated macro-finance model of oil prices and quantities that also determines consumer welfare. We show that shifts in the preferences and constraints...

This paper analyses futures prices for four energy commodities (light sweet crude oil, heating oil, gasoline and natural gas) and five agricultural commodities (corn, oats, soybean oil, soybeans and wheat), over the period 1986-2010. Using CCC and DCC multivariate GARCH models, we find that...

We construct a uniquely detailed, comprehensive dataset of trader positions in U.S. energy futures markets. We find considerable changes in the make-up of the open interest between 2000 and 2010 and show that these changes impact asset pricing. Specifically, dynamic conditional correlations...

This paper addresses the question of whether the oil price spike of 2003-2008 was a bubble. We document and discuss what is known about the level of speculation in the paper oil market. We then analyze the dynamics of the term structure of futures prices, both during the earlier period of...

Investment by oil firms positively affects the futures basis and negatively predicts excess returns on crude oil futures. I build an equilibrium model of drilling, exploration, and storage to understand these facts. Firms' capital stock lowers extraction costs as firms drill in increasingly...

The boom in the production of shale oil in the United States has triggered a structural transformation of the oil market. We show, both theoretically and empirically, that this process has significant consequences for oil risk premium. We construct a model based on shale producers interacting...

According to the macro-econometric literature, the impact of exogenous oil price shocks on Inflation have greatly increased in the last two decades throughout OECD countries while the persistence of those shocks on long-term inflation, namely core inflation, has dramatically decreased. In the...
