Complementarity and Macroeconomic Uncertainty
Macroeconomic uncertainty—the conditional volatility of the unforecastable component of a future value of a time series—shows considerable variation in the data. A typical assumption in business cycle models is that production is Cobb-Douglas. Under that assumption, this paper shows there is usually little, if any, endogenous variation in output uncertainty, and first moment shocks have similar effects in all states of the economy. When the model departs from Cobb-Douglas production and assumes capital and labor are gross complements, first-moment shocks have state-dependent effects and ...

Macroeconomic Responses to Uncertainty Shocks: The Perils of Recursive Orderings
A common practice in empirical macroeconomics is to examine alternative recursive orderings of the variables in structural vector autoregressive (VAR) models. When the implied impulse responses look similar, the estimates are considered trustworthy. When they do not, the estimates are used to bound the true response without directly addressing the identification challenge. A leading example of this practice is the literature on the effects of uncertainty shocks on economic activity. We prove by counterexample that this practice is invalid in general, whether the data generating process is a ...
Modern Refineries, Shale Boom Upend Traditional Oil Price Relationships
Different crude oils can sell for dramatically different prices with sometimes far-reaching effects on the energy industry—from impacts on oil producers’ production decisions to oil refineries’ profit margins.

Did speculation drive oil prices? market fundamentals suggest otherwise
Oil market speculation became an especially popular topic when the price of crude tripled over 18 months to a record high $145 per barrel in July 2008. Of particular interest to many is whether speculators drove oil prices beyond what fundamentals would have otherwise justified. We explore this issue over two Economic Letters. In this article, we look at evidence from the physical market for oil and conclude that fundamentals, and not speculation, were behind the dramatic rise and fall in oil prices. In our companion Economic Letter, we examine the futures market.

The long–run macroeconomic impacts of fuel subsidies
Many developing and emerging market countries have subsidies on fuel products. Using a small open economy model with a non-traded sector I show how these subsidies impact the steady state levels of macroeconomic aggregates such as consumption, labor supply, and aggregate welfare. These subsidies can lead to crowding out of non-oil consumption, inefficient inter-sectoral allocations of labor, and other distortions in macroeconomic variables. Across steady states aggregate welfare is reduced by these subsidies. This result holds for a country with no oil production and for a net exporter of ...

Renewable fuel standards hit the 'blend wall'
The Energy Policy Act of 2005 mandated that a minimum amount of biofuel be blended into transportation fuels. But nine years after the law was passed, the energy landscape has changed.
Geopolitical oil price risk not a major driver of global macroeconomic fluctuations
Notwithstanding the attention geopolitical events in oil markets have attracted, we find that geopolitical oil price risk is unlikely to generate sizable recessionary effects.

Fuel subsidies, the oil market and the world economy
This paper studies the e ffects of oil producing countries' fuel subsidies on the oil market and the world economy. We identify 24 oil producing countries with fuel subsidies where retail fuel prices are about 34 percent of the world price. We construct a two-country model where one country represents the oil-exporting subsidizers and the second the oil-importing bloc, and calibrate the model to match recent data. We find that the removal of subsidies would reduce the world price of oil by six percent. The removal of subsidies is unambiguously welfare enhancing for the oil-importing ...

Reforma Energética: Mexico takes first steps to overhaul oil industry
The fiscal health of the Mexican government and the living standards of Mexico?s citizens are inextricably tied to that of Pemex, making declining crude oil production over the past decade a particularly troubling sign for many in Mexico.

OPEC in the News
This paper introduces a newspaper article count index related to OPEC that rises in response to important OPEC meetings and events connected with OPEC production levels. I use this index to measure how interest in OPEC varies over time and investigate how oil price volatility behaves when the index unexpectedly changes. I find that unexpected increases in the newspaper index are strongly associated with higher levels of oil price volatility, both realized and implied. In some cases, interest levels and price volatility appear to be driven by the OPEC event itself, such as the Iraq invasion of ...
