Any demand equation satisfying Lau’s (1982) Fundamental Theorem of Exact Aggregation and is 0° homogeneous in prices and income will have a Gorman (1981) functional form for each income term. This property does not depend on symmetry or adding up. The implications of this result are...

Agricultural production is subject to supply risk. Expected and realized farm outputs and output prices are unknown and unobservable when inputs are chosen. Crop and livestock production decisions are linked over time. Producers’ expectations are particularly difficult to model. This paper...

From 1998 to 2009 I find that the average time between U.S. households' grocery shopping trips has steadily increased from 4.7 to 6.2 days, and from 1998 to 2006 per capita monthly consumption of fresh fruits and vegetables has decreased from 130 to 112 oz. To understand these changes, a dynamic...

As households shop less frequently, food decay makes perishable food consumption more costly. Therefore, I hypothesize that shopping frequency is an important factor of household food choice. I test this hypothesis using an instrumental variables approach on a system of equations using household...
