Since the mid 1990s, ethanol production has increased at an exponential rate. While politicians and the industry have praised the positive effects of ethanol facilities, it is important to explore the potential negative impacts. This study examines one negative effect that is not yet fully...

With a mandate, U.S. policy of ethanol tax credits designed to reduce oil consumption does the exact opposite. A tax credit is a direct gasoline consumption subsidy with no effect on the ethanol price and therefore does not help either corn or ethanol producers. To understand this, consider...

We examine the effects of the 1990 Clean Air Act Amendments (CAAA) on ambient concentrations of PM10 in the United States between 1990 and 2005. Consistent with prior literature, we find that non-attainment designation has no effect on the average monitor in non-attainment counties, after...

We show how leakage differs, depending on the biofuel policy and market conditions. Carbon leakage is shown to have two components: a market leakage effect and an emissions savings effect. We also distinguish domestic and international leakage. International leakage is always positive, but...

In this workshop the participants identified five priority areas of concern relative to sustainable management of groundwater irrigation by farmers:1) aquifer drawdown; 2) FMIS groundwaterwater support services, 3) management problems under water-surplus conditions; 4) management problems under...

Using a bio-economic model, H2OBeef, that includes traditionally considered parameters associated with running a beef feedlot but also incorporates aspects associated with water, changes that can alter water consumption and or price are examined. The results indicate that when water does not...
