About My Slideshows

This annex is intended as a convenient interface for access to the slide shows that are a key feature of my blog. If you have landed in the annex by accident, click here to return to the main blog.

I originally intended the slide shows mainly for classroom use. If you teach economics at any level, I invite you to cut and paste them into your live lectures, incorporate them into your on-line courses, assign them to your students as readings, or use them in any way that works for you. If you like the slides, I invite you also to consider adopting my own textbook from BVT Publishing.

For general readers of my blog, the slide shows offer a way to explore a topic in greater depth than is possible in the basic post, through added data, graphs, pictures, and background theory and concepts. I hope all readers enjoy them.

The slide shows are published under Creative Commons license Attribution--Share Alike 3.0. That means you can share, transmit, distribute, or adapt the slides for any purpose, provided you cite Ed Dolan's Econ Blog as the source, and your resulting publication is not more restrictively licensed than the original.

Slideshow: US Ethanol Subsidies: A Bad Policy that Refuses to Die

This slideshow discusses the recent renewal of U.S ethanol policy, based on subsidies and tariffs. It argues that ethanol policy fails to have its intended effects of improving the environment and enhancing national security.

Keywords: Ethanol, subsidies, tax credits, trade, environment, comparative advantage, pollution, social cost, externalities.

  1. Dear Sir,
    I am very interested in your slideshow on December 19, 2010 about the ethanol subsidy. I see one big difference between ethanol and oil. By burning oil fuel, we add the intensity of CO2 in the atmosphere permanently, while by burning the ethanol, the emitted CO2 will be reabsorbed later in the next corn planting period. It will follow the same cycle: burning, emitting CO2, reabsorbed by corn plantation, harvesting, distilling, burnt again in the cars, and so on. While the oil fuel follow an open cycle with an almost permanent addition of CO2 to the atmosphere, the corn-based ethanol will be reabsorbed again and again in a closed cycle system.
