Nutrient consumption patterns oflow income households were analyzed using data from the special low income component of the 1977-78 Nationwide Food Consumption Survey. A system of simultaneous equations for estimating food cost and diet component availability levels in home food supply was applied. The derived reduced form showed that Food Stamp Program participation had a positive impact on diet component availability levels. Impacts of other socioeconomic variables examined for diet component availability were generally larger than those for program participation and income. Diet component availability levels were relatively constant across households with different income and Food Stamp Program bonus levels.

Recent expansions in biofuel production have led to concerns about an emerging “new relationship” between energy prices and the prices of agricultural feedstock for biofuel. We provide new econometric evidence on this relationship using common trend‐common cycle decompositions to estimate long‐run and short‐run co‐movement across various energy and agricultural prices. We also test for the presence of regime changes that may alter the relationship between energy and agricultural feedstock prices under certain conditions. We find that co‐movements between energy and agricultural feedstock prices tend to dissipate in the long‐run, which has important implications for biofuel and food policy.
