Does credit availability exacerbate asset price inflation? Are there long run consequences? During the farm land price boom and bust before the Great Depression, we find that credit availability directly inflated land prices. Credit also amplified the relationship between positive fundamentals...

Agricultural and energy commodity prices have traditionally exhibited relatively low correlation. However, recent increases in biofuel production have altered the agriculture-energy relationship in a fundamental way. This increase has drawn on corn previously sold to other uses, as well as...

Grain shippers and political figures in North Dakota and nearby states have voiced concern that the dramatic increases in shipments of crude oil by rail have caused service delays and higher costs. We investigate the potential impact of crude shipments on grain markets accounting for harvest...
